Full textHoverflies are a very important and useful insect group. They provide irreplaceable environmental and economic services, as well as environmental services. These services are enabled by their ability to pollinate plants in natural and agroecosystems, as well as thanks to larvaepredators of aphids and other insects, reducing economic losses in the yield of cultivated plants. Hoverflies are extremely important for the environment, as they can serve as bioindicators of climate change and habitat conditions. Some species also have conservation importance, since they have become endangered due to anthropogenic effects, which requires taking measures to ensure their survival. The extraordinary richness of flora and fauna on the Balkan Peninsula represents a unique ecological and biogeographical phenomenon in Europe. Greece, as one of the most important center of biodiversity in the Balkans and in the Mediterranean, is characterized by a wide spectrum of important ecosystem types, the most important of which are forests, since the largest number of hoverflies prefer this type of habitat.The importance of faunal research is reflected in the discovery of the composition and number of species in specific habitats or areas. The faunal composition provides an insight into the biodiversity of the investigated area, which is constantly changing, especially lately under the influence of negative anthropogenic impact. Data about species can be of great importance for possible programs for the protection and recovery of endangered species, as well as in the planning of the formation of new protected areas or in the introduction of new measures of protection in already existing natural resources. Identifying endangered species or endangered habitats they inhabit plays an important role in planning conservation strategies for their conservation.The results of these thesis complement the knowledge of the fauna composition, taxonomy, distribution and diversity of hoverflies in Greece. Using the collected data, an identification key was formed to distinguish both the genera and species registered in this area, which greatly assisted in further faunistic research. As a result of these thesis a final list of 418 species rom 83 genus was obtained. Of the total number of recorded species, 64 species were first time registered in the territory of Greece, while a total of 18 species are new to science. The main goal of this paper is to revise the fauna of Greek howerflies based on the collected material from published and unpublished collections and additional field research, compile a list of all known species from Greece, and create an identification key to distinguish the recorded genera and species (accompanied by photographs and drawings of diagnostic morphological characters of adult individuals). The second part of the thesis deals with the identification of rare and endangered species of Greece with an emphasis on their protection and conservation. Within the framework of the dissertation, a spatial analysis of the distribution of species in Greece was carried out, already threatened at the European and Balkan levels, in order to determine areas of specialsignificance for their preservation.

Full textThe main objective of this work is to examine distribution of Lithuanian loaches, abundance and difference of their populations in Lithuanian inland waters, as well as factors conditioning selection of habitats, determine the taxonomic status and distinguish forms, subspecies or species. Novelty of the study: Loach has not yet been investigated in Lithuania, and earlier investigations into ichthyocenoses do not reflect the status, distribution, abundance and status of loaches. In dissertation are examined loach population status, distribution and abundance in Lithuania. The northern golden loach which is a new species for Lithuania was detected during this investigation and described and examined. The complex structure of spined loach populations is examined, which reveals the existence of now polyploidy hybrids in Lithuania. The knowledge of distribution of the golden loach is extended on a European scale. New information on biotypes of Cobitis taenia complex is presented and their biogeography is supplemented. The dissertation consists: The dissertation consists of the following chapters: Introduction, Literature Review, Material and Methods, Research Results and Discussion (consisting of 6 subchapters), Conclusions, Recommendations, References, List of Author’s Publications and Conference Abstracts. All the material is presented in 168 pages; Material and Methods, and Research Results and Discussion are presented in 103 pages. The list of references includes 137 sources... [to full text]

Full textThe PhD research project is a study of fauna of spiders (Arachnida, Araneae) of Macedonia based on a critical analysis of published data covering the period from 1907 to 2018, taxonomic review of relevant arachnological collections from eight European Natural history museums and the results of author’s thirty years of research. Field work is based on the collection of materials using standard methods such as manual collection and trapping and a newer method using a motor vacuum cleaner. The material was processed with standard procedures using a dissecting binocular and a microscope.A total of 742 species of spiders from 40 families have been registered. Five taxa are new species for science. Two species present new findings for the fauna of the spiders of the Balkan Peninsula. Sixty two taxa were recorded for the first time for the fauna of Macedonia.An ancient family Anapidae with one species has been registered for the first time in the fauna of Macedonia. By reviewing the published data, it was established that 179 species were incorrectly identified and listed for the fauna of Macedonia. Species are categorized according to the current knowledge of their distribution, on the basis of which a zoogeographic analysis of the fauna was performed.32 chorotypes were established in the fauna of the spiders of Macedonia, classified into four chorological complexes: widespread, European, Mediterranean and endemic species. The largest number of species is registered in the complex of widespread species (44.3%), which give the main character of the fauna. The high degree of representation of European (19.1%) and Eurosiberian (11.3%) chorological elements, as the two individually most represented in the fauna of the spiders of Macedonia, is a reflection of the dominant mountain character of the relief of Macedonia. The chorological complex of Mediterranean species is represented by 99 species (13.3%). The high proportion of species (11.3%) belonging to the chorological elements that are present on the territory of Southern Europe, the Mediterranean, West and Central Asia speaks of the rich fauna of spiders of xerophilic, thermophilic and arid terrain. The local character of the fauna can be seen in a relatively large number of species from the complex of endemic species (87). From this complex are the most dominant species from the chorotype "narrower endemic" with 45 species.Western Macedonia is the richest with fauna of spiders, with 23 species from the group of endemites of the narrower area, which speaks of the great importance of this region as a refugium and space in which the processes of speciation were intensively carried out.

Full textThe objects of this study are species from Merodon aureus, M. nanus and M. ruficornis groups, and M. avidus complex in Palaearctic. These species are characterised by great morphological similarity, and three different approaches were used to detect cryptic species and establish species boundaries. Species from M. aureus and M. nanus groups, and M. avidus complex were analysed using geometric morphometry. Interspecific variability of M. aureus group and M. avidus complex were studied using two approaches: landmark based wing shape analysis and semilandmark analysis of male genitalia. Ecological niche analysis were conducted for all analyzed species. Correlation between Squared Mahalanobis distances of both wing and surstylus, and geographic and environmental distances were addressed using the two tailed Mantel test. Geometric morphometric results indicate that wing and especially surstylus shape, have meaningful interspecific discriminatory power. Based on these characters 45 evolutionary independent units are recognized (M. aureus group - 36; M. nanus group - 5, M. avidus complex - 4). All cryptic species from 12 analysed species complexes were successfully distinguished with high overall classification success. Results showed that geometric morphometry of surstylus had a higher classification rate than wing geometric morphometry. The main wing shape differences are connected with apical part of the wing which influences his length and width. The main differences in surstylus shape are connected to the posterior margin of the posterior part of the surstylus lobe, involved in gripping the female during copulation. Mantel tests revealed that geographic and environmental distances exhibited no association with wing and surstylus shape distance among investigated species, except in M. luteomaculatus complex. In this complex, Mantel test results suggested that isolation by distance had a major role in the diversification of male genitalia.Ecological niche analysis contributed to the species delimitation. These results demonstrated that among all related species, with the exception of species pairs M. rojoi - M. puniceus and M. loewi - M. ovaloides, overall or partial divergence in environmental space is present. Distribution patterns of all analyzed species are mainly affected by the limiting effects such as low temperature and precipitation values, as well as the temperature fluctuation during the year.Endemics and species with a narrow range had smaller altitudinal ranges and were mainly connected with mountainous areas. Additionally, low standard deviation values for endemic species reflect their narrow geographic distribution and very strict climatic adaptations, whereas large values for widely distributed species reflect their broad adaptability.According to the results of distribution and species diversity analysis, the Balkan Peninsula is characterized with highest diversity. It is a centre of biodiversity for M. aureus group, together with the northern part of the Apennine peninsula for M. ruficorn is group, while the largest species diversity of M. nanus group is recorded in the southwest and northeast Anadolia.Distribution and species diversity analyses, together with the results of geometric morphometry indicate that geological history, i.e. range contraction during glaciations and interglaciations had a significant impact on the diversification of the studied groups in refuges in the Western Palaearctic.

Full textOrnithogalum sect. Heliocharmos is a taxon of exceptional characteristics that make it concurrently variable and simple. With the distribution in North Africa, Europe and Southeast Asia, it is a large-scale taxon in the Hyacinthaceae family. Although known from the pre-Linean period, a systematic approach to research was rare and related to certain geographical areas. In order to contribute to the modern knowledge of the taxon, the goals of the research primarly have the revision of the nomenclature, taxonomy and distribution in the area of the Balkan Peninsula and the Pannonian Plain. The study included 15 taxa: ser. Platyphylla and species O. comosum, O. montanum, O. oligophyllum and O. fimbriatum, and ser. Tenuifolia and O. exscapum, O.dalmaticum, O. kochii, O. orbelicum, O. umbellatum, O. divergens, O. refractum, O. sibthorpii and unnamed hybrid. A review of the nomenclature includes a separate chapter a critical overview of the etymology of the genus Ornithogalum. Taxonomic status is determined based on morphometric and cytotaxonomic studies. Morphometric analyzes included morphological characteristics of ‘herbarum data', flowers and ovary, as well as comparative anatomical structure of leaf and scape. In addition, qualitative morphological characteristics and micromorphology of seeds and testa were analyzed in particular. Data were analyzed by standard statistical methods for defining taxonomic information characteristics and determining separate groups within the analyzed taxon: Multivariate correspondent analysis for qualitative characters and analysis of variance and Discriminant analysis for quantitative characters. For the analysis of qualitative and quantitative characteristics, the Factoraial analysis of mixed data was used. The results of statistical data were used to create a dichotomous key of the Heliocharmos section type. Cytotaxonomic studies, the number of chromosomes and the genome size in selected taxons are included in the study, and cytotoxonomic status for the date of the species is presented. In order to examine the influence of the environmental factors on the section Heliocharmos, the correlation between selected ecological indicators and phytohemical compounds in the species Ornithogalum umbellatum was examined. Taxonomic conclusions were preceded by the revision of regional and European herbarium collections: BEO, BEOU, BP, BUNS, K, LJS, LJU, MKNH, PO, SARA, SO, SO, SOA, V, VU, ZA, ZAGR, ZAHG, ZAHO; digital collections were also revised: B, BM, BRNU, E, F, FI, G, GE, GZU,HAL, JE, MJG, NAP, OKSF, PI, U, MV. Based on the results and conclusions of the taxonomic part of study, and with the results deposited in the created herbarium database, the distribution of the species Ornithogalum sect. Heliocharmos is shown. In addition to reviewing the distribution of data, there is an overview of the general range of species and habitats preferences.Revision of nomenclature, taxonomy and distribution of the species Ornithogalum sect. Heliocharmos in the Balkan Peninsula and the Pannonian Plain gave an overview of the current knowledge of the investigated taxon. The undoubted importance of the investigated area for the diversity of the genus Ornithogalum was confirmed. All the characteristics, have shown a degree of variability but they also confirmed their taxonomic significance. Using different combinations of taxonomic characters, each species can be clearly described. Such a proposal also points to disadvantages in the systematic approach of Ornithogalum sect. Heliocharmos, that need to be further investigated.

Full textTiivistelmä Laji on luonnon monimuotoisuuden perusyksikkö, mutta lajien tunnistaminen ja rajaaminen on usein vaikeaa. Vaikeudet korostuvat erityisesti hyvin monimuotoisissa eliöryhmissä kuten hyönteisissä. DNA-viivakoodit ovat lyhyitä standardoituja DNA-sekvenssejä, joiden käyttö lajien tunnistamisessa sekä yhtenä tiedon lähteenä lajien rajaamisessa on viime aikoina yleistynyt nopeasti. Tutkin väitöskirjatyössäni DNA-viivakoodien soveltuvuutta lajinmääritykseen ja lajien rajaamiseen kovakuoriaisilla. Kovakuoriaiset ovat yksi maailman lajirikkaimmista eliöryhmistä: lajeja on kuvattu lähes 400000. Pohjois-Euroopan lajisto tunnetaan koko maailman mittakaavassa poikkeuksellisen hyvin, mikä tarjoaa erinomaiset edellytykset tutkia DNA-viivakoodeihin liittyviä kysymyksiä kuoriaisilla. Tutkin DNA-viivakoodeja myös kokonaan uudesta näkökulmasta, selvittäen aminohappotason muuntelua koko eläinkunnan kattavassa otoksessa, sekä laajalla perhos- ja kuoriaisaineistolla. DNA-viivakoodit osoittautuivat erinomaiseksi työkaluksi lajinmääritykseen: riippuen onnistuneen määrityksen kriteereistä 95–98 % kuoriaislajeista voitiin tunnistaa luotettavasti viivakoodien perusteella. Käytetystä menetelmästä riippumatta noin 90 % nykykäsityksen mukaisista lajeista voitiin rajata viivakoodien perusteella oikein, ja soveltamalla yksinkertaisia konsensus-sääntöjä yhteensopivuus lajien ja viivakoodiklustereiden välillä kasvoi entisestään. Useat kuoriaislajit, jotka jakautuivat kahteen tai useampaan viivakoodiklusteriin, sisältävät alustavien morfologisten tutkimusten perusteella aiemmin huomaamatta jääneitä uusia lajeja. Aminohappo- ja proteiinitason tutkimus osoitti, että viivakoodijakson koodaaman proteiinin rakenne on yleisesti ottaen konservoitunut kautta eläinkunnan. Havaitsin kuitenkin myös useita kiinnostavia aminohappo-muutoksia, jotka saattavat vaikuttaa entsyymitoimintaan. Aminohapposekvenssi muuntelee kuoriaisilla paljon enemmän kuin perhosilla, mahdollisesti johtuen taksonien välisistä eroista molekyylievoluutiossa ja viivakoodisekvenssiin kohdistuvassa valintapaineessa

Full textA comparative analysis of morpho-anatomical and micromorphological characteristics of leaf, stem, rhizome, root, fruit and receptacle, as well as biochemical analysis of essential oils of underground organs, was conducted over 16 species of 4 genera, Inula (I. aschersoniana, I. bifrons, I. britannica, I.conyza, I. ensifolia, I. germanica, I. helenium, I. oculus-christi, I. saslicina ssp. salicina, I. salicina ssp. aspera, I. spiraeifolia), Dittrichia (D. graveolens, D. viscosa), Limbarda (L. crithmoides) and Pulicaria (P. dysenterica, P. vulgaris) tribe Inuleae, Compositae. In addition to the fact that the species from different genera analysed in this paper were previously placed in different sections within Inula, I. helenium L., as the type species of the genus Inula, has also been placed in a separate section Corvisartia. According to the latest molecular phylogenetic analyses, based on plastid and nuclear DNA sequence data, as well as morphological and karyological data, it is suggested that section Corvisartia should be segregated from the remaining Inula species as a separate genus, thus achieving a greater morphological homogeneity of the genus Inula. The objectives of dissertation are defined in accordance with the fact that the data on the morpho-anatomical, micromorphological and biochemical structure of the vegetative and reproductive organs of species of examined tribe are sparse and incomplete, while the analyses were carried out on few species of Inula, Pulicaria, Dittrichia and Limbarda, but less emphasis was placed on comparative purpose. The research involved a large number of qualitative and quantitative characters that were analysed and measured using a stereomicroscope, light, fluorescent and scanning electron microscope. The obtained data were statistically processed by various numerical analysis methods usually used in taxonomic research. These types of analyses for the species of the generaInula, Dittrichia, Limbard and Pulicaria have not been recorded in the literature so far. The conducted analysis showed that vegetative organs do not provide enough information on the basis of which certain groups of species could be singled out with statistically significant suport, neither the genera according to the actual classification. The yielded results indicated that the species from different genera were clearly delimited on the basis of their carpological and receptacular micromorphological and anatomical characteristics. Receptacle features and organisation of sclerenchyma tissue in a fruit are traits that tend to be diagnostic for genera. The features that separate analysed taxa are: two rows of pappus hairs in Pulicaria species; the ring constriction of the fruit over which it passes into pappus, the sclerenchymatous tissue in fruit in form of continuous ring, the type of trichomes on the receptacular surface in Dittrichia species; the fruit with secretory ducts, and the receptacular surface with weakly pronounced ridges without glands in L. crithmoides. I. helenium fruits differ from those of all the other species by their size, greater number of inconspicuous sclerenchymatic bundles, and poorly expressed ridges among carpopodial prints with glandular and non-glandular trichomes distributed along them. Results revealed that I. helenium stands out as a separate taxon, based on the anatomical and micromorphological characteristics of its fruit and receptacle, with equally small percentage of statistical support, which also supports the recognition of Pulicaria, Dittrichia and Limabarda as separate genera. Obtained results support the claim that I. helenium should be separated from the Inula genus, whereby its authenticity is evident at the level of anatomy and micromorphology of vegetative and reproductive organs. The chemical analysis of the essential oil has provided new data on the qualitative and quantitative composition of the essential oil of the underground organs of the analysed taxa and pointed out the possibility of their application in taxonomy. Also, the obtained results indicated potentially new medicinal plants that represent a potential resource for the pharmaceutical industry. Principal component analysis as well as the results of the Correspondent analysis indicated the absence of the grouping tendency of taxa belonging to the same genus, according to the actual classification. Due to the high variability conditioned by the environmental factors the composition of essential oils cannot be used independently as a reliable chemotaxonomic marker. However, the results of the composition of essential oils are significant in terms of their application for medical and cosmetic purposes, in the industry where oils are used as raw materials, and the results obtained are also significant in the context of evaluation of the quality of investigated essential oils.The conducted research makes a significant contribution to more precise classification within the tribe, which is now basedmainly on morphological characteristics. The detailed description of morpho-anatomical and micromorphological characters of the analysed vegetative and reproductive organs contributes to better knowledge of the characteristics of the analysed species and complements the existing data on them. Also, on the basis of morpho-anatomical characteristics of the fruit and the receptacle a dichotomous key for the determination of the analysed genera and species was developed. According to the Discriminant and Correspodent analysis the characteristics on which is possible to discriminate certain groups within the analysed genera are also distinguished.

Full textCurrent systematic Synocheta section at almost all levels fails to reflect the real phyletic relations. Unusual distribution and vague differential characters of Styloniscidae family and its relationships with the Trichoniscidae family are problematic. The division criteria for forming Trichoniscidae subfamilies are unclear, inconsistent and often unenforceable. Hence, the extremely simplified division that does not reflect the real phyletic relations within the group, which are much more complex, is not surprising.Of 593 Synocheta species, one third (mostly endemic) inhabit the Balkans, which imposes this area as one of the centers of diversification and diversity of the group, and makes it ideal for the analysis of real phyletic relations. This defined the main goals of our study: as complete assessment of the fauna of the Balkan Synocheta as achievable through taxonomic treatment; determining phyletic relations through comparative analyses based on the complex of relevant characters, with the emphasis on the more conservative ones, which has not been accomplished thus far.In the Balkan fauna of the Styloniscidae family, 4 genera with 15 species were identified, of which 3 genera and 4 species are new to science; similarly, the 33 genera with 176 species from the family Trichoniscidae found in Balkan fauna included one new genus and 18 new species. Of that number, 27 genera and 161 Synocheta species are endemic to the Balkans.In Styloniscidae, we found much greater diversity and heterogeneity than was previously established, which indicates that these groups possibly originate from the northern Gondwana (partly incorporated into the Balkans area), in common with Trichoniscidae family.We reconstructed the most important moments in the Trichoniscidae philogeny: early development of conglobation, with massive integument and developed rnamentation as adaptations; transition into protection via stereotaxation; evolution toward more active protection and loss of "armor", which leads to extensive adaptive radiation. In addition, we have shown that the characters that were previously considered derived properties are actually plesiomorphic.We have presented the basic evolutionary trends in Trichoniscidae family, as well as phyletic relations arising from this study: Haplophthalminae are the ancient group ossessing a wide range of plesiomorphic characters; Buddelndiellinae are the ancient group with a much VI closer phyletic relations to Haplophthalminae; Thaumatoniscellinae share a common, and very distant, origin with Haplophthalminae; Trichoniscinae are a younger paraphyletic group and many lines have evolved independently of the Haplophthalminae subfamily.In this study, in some segments, we have demonstrated substantially more complex phyletic relations within Synocheta, diametrically opposed to the previously presented findings.

Full textUnlike the highly diversified and species-rich genera of European orchids, such as Ophrys or Epipactis, the genus Anacamptis has remained quite neglected in orchidological research. Representatives of this genus, together with many others genera, were investigated mainly by molecular methods. Also, extensive studies have been done, but only on specific species. Morphological studies were very rare, and with a few exceptions, limited to geographically small areas and one or more morphologically similar species. Analysis of the morphological variability of so many taxa of the genus Anacamptis, in a is, in a geographically relatively large area such as the Balkan Peninsula, as geographically relatively large area such as the Balkan Peninsula, as well as the southern part of the Pannonian Plain, has not been conducted so far. Morphological analyses wereperformed on almost all representatives of this genus,in the species and subspecies rank , occurring in the Balkan Peninsula mainland, as well as in the southern perimeter of the Pannonian Plain. Comparativemorphological analyses were conducted using the methods of basic, univariate and multivariate statistics.So far, the largest study of the genus nacamptis, by the number of processed individuals and the area in which it was conducted, included 2001 individuals from 185 populations. Natural populations and material from the BUNS Herbarium were analyzed. A total of 69 morphological characters, quantitative and qualitative, were defined, and those that have a potentially differential character among analyzed species and infraspecific taxa were selected. The analyzes also included interpopulation morphological variability within each taxon, to identify the existence of specific geographic patterns of its changes. The morphological characters that proved to be taxonomically informative, were used to form the dichotomous key for the determination of the genus Anacamptis members, presented in the study area. The analyzes identified a large number of characters that were statistically significantly different between the analyzed populations, subspecies, and species. Most of the characters showed moderate or low variability, and in rare cases increased variability. Flower’s characters were statistically significantly correlated with each other, most of them weakly to moderately, while those of the sepals and petals, as well as between the labellum and other parts of the flower, were very strongly correlated. The only taxon that has not shown any infraspecific differentiation (except A. boryi), and which is characterized by high intra- and interpopulation variability, is A. pyramidalis. For the same reason, it has been shown as unjustified to separate individuals from different parts of species range into infraspecific forms. The low morphological variability of the narrowly distributed A. boryi was confirmed. In all other taxa studied, the existence of certain patterns of geographical interpopulation variability and infraspecific structuring was detected. A. laxiflora subsp. laxiflora populations can be divided into two groups – Adriatic and Continental, with the lowest characters values measured among the westernmost populations. A. coriophora subsp. fragrans proved to be less variable than the type subspecies, but within it, a new variety (var. hermae) as phenological, ecological and morphologically distinct from other studied populations was described. The typesubspecies has a transition of morphological variability in a west-east direction. The characters that are the most important for differentiation of A. palustris subspecies are the bract length and width, the degree of labellum differentiation into lobes, and the depth of the sinuses that separate them. Populations of A. palustris subsp. elegans can be divided into three geographically and morphologically defined groups – Eastern Balkan, Western Balkan and peripheral populations from the North Serbia and Slovenia. Differential characters among the Laxiflorae section taxa are ration between the ovary length and bract length, as well as the labellum middle lobe length. For the first time, species A. morio is morphologically and geographically divided into two subspecies, in the study area. Analyzed subspecies have great overlapping values for many morphological characters, but both are characterized by specific flower’s characteristics, above all labellum shape. On this basis, it is possible to distinguish them. Areals of A. morio subspecies were defined – the type subspecies is predominantly northern and western,while subsp. caucasica is southern and eastern. The first is characterized by larger flowers, renal shape labellum with a median lobe that does not exceed significantly the length of the lateral ones, while the second subspecies has smaller flowers and strongly projecting the median lobe. Both subspecies can be divided into groups of populations that have clearly defined geographical distribution. For the first time, A. papilionacea was morphologically investigated on a larger number of specimens, unlike previous researches in which individual specimens from different parts of the range were simply compared. Morphological differentiation into two subspecies was shown – type and subsp. aegaea. They are morphologically distinct and occupy different parts of the species range. Within the subsp. papilionacea a clinal distribution of morphological variability in the north-south direction was recorded. Three taxa of hybrid origin, new for the area of North Macedonia (A. × gennarii), Montenegro (A. × parvifolia) and Serbia (A. × timbali) were registered. Hybrids exhibit a general morphological intermediacy between parents but are also distinguished by new character states that were not observed inparental taxa. Similar patterns of morphological variability, both at the interpopulation level ofindividual species and between the subspecies of each species studied, show a clear relationship between the studied taxa and once again justify their grouping into the genus Anacamptis.

Full textIn this master thesis we analyse a problem of reengineering of a distance study system, in general, and the learning material of a separate course, in particular. Reengineering concept with its different interpretations is used in software engineering and management sciences. It deals with making systems better maintainable, examination and reconstitution of the system for further reimplementation. We combine the meaning of reengineering concept in both mentioned areas and employ it as methodological background in distance study area. We analyse the structure of the distance study course. Then we introduce the courses, prepared and delivered in foreign universities and related to ‘Programming in GUI’ course, triple consistency principle, Bloom taxonomy and its applicability to computer science studies, Computing Curricula 2001. Further, we propose a conceptual distance study course reengineering framework from the lecturer’s perspective and present a case study, in which two topics were reengineered, considering triple consistency principle and requirements for computer science students.

Full textDoktorska disertacija predstavlja taksonomsku studiju testatnih ameba Istočne Hercegovine baziranu isključivo na rezultatima sopstvenih istraživanja s obzirom da na ovom području testatne amebe do sada nisu proučavane, te ne postoje istorijske muzejske kolekcije. Na području Istočne Hercegovine registrovano je 40 vrsta testatnih ameba koje su svrstane u 10 familija i jedan rod bez jasnog mesta u klasifikacionom sistemu. Svi registrovani taksoni testatnih ameba su novi za faunu Bosne i Hercegovine. Ukupno je analizirano 24.549 jedinki, od čega su 23.242 jedinke pripadale grupi testatnih ameba sa lobopodijama (supergrupa Amoebozoa), a 1307 jedinki je pripadalo grupi testatnih ameba sa filopodijama (supergrupa Cercozoa). Najznačajniji rezultat ove disertacije je opis pet novih vrsta za nauku koje pripadaju rodovimaCentropyxis, Heleopera i Nebela. Morfotip označen kao C. cf. aerophila se od vrste C. aerophila razlikuje po tome što se na kraju ljušturice ne nalazi par krupnih čestica kvarca,a i ljušturica je nešto duža (46‒81 μm kod vrste C. aerophila prema 67‒ 88 μm kod vrste C. cf. aerophila). Morfotip označen kao C. cf. platystoma značajno se pre svega morfološki razlikuje od vrste C. platystoma, te je zaključeno da se radi o neopisanoj vrsti.U okviru roda Heleopera opisan je novi morfotip sličan vrsti H. rosea koji predstavlja novu vrstu za nauku. Morfometrijske razlike su relativne, tj. nisu strogo diskriminatorne, te se moraju kombinovati sa morfološkim razlikama koje su takođe teško yočljive. Naime, pored razlike u boji ljušturice, najbolji diskriminatorni morfološki karakter je opšti oblik ljušturice. LJušturice vrste H. rosea su robusnog oblika, dok su ljušturice vrste Heleopera cf. rosea znatno elegantnije ‒ uže su i imaju oblije ivice. Najveće morfometrijske razlike u indeksnim karakterima su zabeležene za odnos širine i dužine ljušturice i odnos širine aperture i širine ljušturice.Morfotip Nebela cf. collaris se od vrste N. collaris jasno razlikuje pre svega morfološki i ekološki, a morfometrijski veoma malo. Naime, najvažnija morfološka odlika koja morfotip N. cf. collaris razdvaja od vrste N. collaris su talasaste ivice ljušturice, a ekološka razlika se javlja u smislu da vrsta N. collaris naseljava zelene mahovine dok morfotip N. cf. collaris naseljava sfagnumske mahovine. Morfotip N. cf. tincta var. major se od morfotipa N. cf. collaris razlikuje pre svega po jasno izraženom suženju u delu blizu aperture, tj. izraženom vratu. Takođe, morfotip N. cf. tincta var. major nikada nema talasaste ivice ljušturice,dok se kod jedinki morfotipa N. cf. collaris ova karakteristika često jasno uočava.
The PhD thesis is a taxonomic study of testate amoebae from East Herzegovina based exclusively on the results of our own research, given that testate amoebae have not been studied in this region so far, and there are no historical museum collections. In the region of East Herzegovina,40 testate amoeba species have been registered, which are classified into 10 families and one genus without a clear place in the classification system. All registered testate amoeba taxa are new to the fauna of Bosnia and Herzegovina. A total of 24,549 individuals belonged to the group of testate amoebae with lobopodia (supergroup Amoebozoa), and 1307 individuals belonged to the group of testate amoebae with filopodia (supergroup Cercozoa). The most significant results of this PhD thesis are the descriptions of five new species for science belonging to the genera Centropyxis, Heleopera, and Nebela. The morphotype Centropyxis cf. aerophila differs from C. aerophila in that there is no large quartz particles at the shell end, and the shell is slightly longer (46‒81 μm in C. aerophila versus 67‒88 μm in C. cf. aerophila). The morphotype C. cf. platystoma differs significantly morphologically from C. platystoma, so it was concluded that it is an undescribed species. Within the genus Heleopera a new morphotype similar to H. rosea has been described, representing a new species for science. Morphometric differences are relative, i.e. they are not strictly discriminatory, and must be combined with morphological differences that are difficult to detect. Namely, in addition to the difference in the color of the shell, the best discriminatory morphological character is the general shell shape. Shells of H. rosea are red and robust in shape, while shells of H. cf. rosea are volet and much more elegant ‒ they are narrower and have rounded edges. The largest morphometric differences in the index characters were observed for shell width/shell length ratio and aperture width/shell width ratio. The morphotype Nebela cf. collaris clearly differs from N. collaris primarily morphologically and ecologically, but morphometrically very little. Namely, the most important morphological character that N. cf. collaris separates from N. collaris are the wavy edges of the shell, and the ecological difference occurs in the sense that N. collaris inhabits green mosses while N. cf. collaris inhabits Sphagnum mosses. The morphotype N. cf. tincta var. major from the morphotype N. cf. collaris differs primarily by a clearly pronounced narrowing in the part near the aperture, i.e. pronounced neck. Also, the morphotype N. cf. tincta var. major never has a wavy edge of the shell, while in N. cf. collaris this feature is often clearly observed.

Full textHoverflies represents a large family of Diptera that have in the ecosystem an important role of pollinators and decomposer of organic matter. They are also a good indicator of ecosystem disruption. Therefore, knowledge of their taxonomy and ecology is of great importance. One of the three most numerous genus of hoverflies is the genus Eumerus, whose revision in the Balkan Peninsula is the subject of this dissertation. The Balkan Peninsula is an exceptional center of biodiversity, for hoverflies among other families. For the genus Eumerus, Balkan Peninsula is next to Central Asia and South Africa, one of the centers of speciation. Representatives of the genus Eumerus are mostly small black flies, sometimes with red abdomen. They are characterized by white stripes on the tergites, two rows of spines on the metafemur apico-ventrally and recessed upper outer transverse wing vein. The aim of this dissertation was to determine the number of species on the Balkan Peninsula and to resolve their taxonomy. As a result, 44 species were identified in the investigated area, which are divided into ten groups based on the morphological similarity. The three species identified do not belong to any group. In the course of this study, 12 new species were discovered for the science: E. aurofinis, E. banaticus, in litt., E. bicornis, in litt., E. crassus, E. karyates, in litt., E. montanum, E. montenegrinus, E. nigrorufus, in litt., E. phaeacus, in litt., E. rubrum, E. tenuitarsis, in litt. and E. torsicus. The geometric morphometry of the wings gave excellent results for the separation of cryptic taxons within the genus Eumerus, applied to the species of the minotaurus group. The most important morphological characters for differentiating species were determined. One of the very important results of this dissertation is the identification key for species of the genus Eumerus on the Balkan Peninsula. Based on morphological analysis, conclusion is that the tricolor group represents a morphologically separate taxonomic entity with clear indications that its rank is above a group of species. The centers of diversity of the genus Eumerus in the research area represent, according to the species richness of the Greek island of Lesbos and Corfu and the southeastern part of Montenegro including the Skadar Lake. Based on the Shannon’s Diversity Index, the areas with the highest index are as follows: the islands of Hios, Lesbos and Corfu, then Peloponnese and most of Montenegro.

Full textThe experience of working with university students has shown that the learning outcomes of linguistic courses are infrequently satisfactory, which is also described in literature worldwide. Teaching philosophy in which students are forced into passives roles is one of the causes since such teaching results in low motivation with memorizing and reproduction of learned materials as the most frequent outcomes of learning. Biggs (1999) develops the concepts of deep and superficial learning approaches which have been declared in the relevant literature as key factors for the quality of learning outcomes. Deep approach to learning correlates with high quality learning outcomes, and is characterized by high motivation, satisfaction with learning and student activity of appropriately high cognitive levels. Higher cognitive functions (Bloom et. al. 1956, Anderson at al. 2001) and related cognitive activities (problem solving, analytical, critical and creative thinking) are the most important goals of higher education since these thinking skills are transferable and therefore represent applicable and functional knowledge. The training and development of the higher cognitive skills enables students to use deep approaches to learning, which is an additional reason to consider them as fundamental teaching goals in all courses in tertiary education. Based on this theoretical framework the main hypothesis and sub-hypothesis were formulated as follows: the use of specially designed practices which activate higher cognitive functions (HCF) will result in acquiring functional knowledge at both theoretical and practical levels; the knowledge gained through such teaching will reflect the use of higher cognitive functions: apply, analyze, evaluate, create, as well as show problem solving skills and critical and creative thinking. To test the hypotheses an experiment was conducted with the first year English language students (N=34) at the Faculty of Legal and Business Studies dr Lazar Vrkatić in Novi Sad. In the parallel groups design, the experimental group (EG) was involved with activities which develop HCFs in the course of Introduction to General Linguistics during the winter semester of the 2012/2013. Quantitative data were collected at the end of the semester (the final test) and compared between the two groups to determine whether the EG scored better results than the control group (CG). This was followed by interviews with five respondents from each group to qualitatively compare the cognitive processes. No statistically significant difference between test results in the two groups was found and so the main hypothesis was rejected. The coded data from the interviews showed an equal number of identified CFs with both groups with similar distribution patterns, thus the sub-hypothesis was also rejected. The absence of better scores of the EG can be explained by some methodological limitations of the experiment, such as the length of the experimental activities, the problem of proof of transfer and the coding of the interview data. Other factors include the existing learning habits of students, the inability to grasp the purpose of studying linguistics, etc. The results of better students were compared to those of the weaker ones, which showed that better students are more autonomous, use a greater number of HCFs and string more CFs into a complex response. Qualitative data also showed that better students of the experimental group expressed a change in how they see the world around them and express satisfaction because of studying linguistics. They also string the longest chains of cognitive activities. These findings lead to a conclusion that better students of the EG used deep approaches to learning which resulted in higher quality learning outcomes. In order to achieve conclusive results, a comprehensive long-term multidisciplinary research project should be carried out, since its results would have a significant impact on the quality of learning outcomes in tertiary education.

Full textA new species of the family Diplozoidae is described from 'the Vaaldam, Transvaal, South Africa. This species Paradiplozoon kimberleyensis n. sp., was initially found on the gills of the large mouth yellow fish Barbus kimberleyensis Gilchrist and Thompson, 1913 and later also on the.gills of the small mouth yellow fish Barbus aeneus (Burchell, 1822). Parasites collected from these fishes were studied with the aid of whole mounts, serial paraffin and methyl acrylate sections and the electron microscope. P. kimberleyensis n. sp. differs from the other African diplozoons with respect to the position of the productive system relative to the region of fusion, the lobular 'structure of the testis and the absence of the egg filament. Reconstructions of the reproductive system and prohaptoral region were used in describing the relevant structures. From these, it was clear that the vas deferens of one individual is fused to the common vitelline duct of the partner in copulation. Furthermore, the relations of the different parts of the reproductive system with respect to each other, could clearly be demonstrated. The physiological reproductive processes (i.e. oogenesis, spermatogenesis and vitellogenesis) of P. kimberleyensis n. sp. follow the basic pattern of other monogenean parasites. The various components of the reproductive system were discussed and compared with those of other diplozoons. Finally, the biological significance of the fusion of two separate individuals into a functional unit and the possible ways in which this phenomenon was accomplished were discussed.

Marais se verskuns word onder meer as “groen”, “omgewingsgerig”, “ekopoëties”, “bioregionaal” en “biogeografies” beskryf en kritici is dit eens dat sy oeuvre ‘n sterk bewaringsingesteldheid vertoon. Marais se eiesoortige bydrae tot die bewaringsdiskoers (deur sowel sy verse as kritiese uitsprake) word hier geëvalueer aan die hand van sekere sleutelkonsepte uit die museum- en bewaringswetenskap wat telkens as metafore in sy poësie figureer: taksonomie, taksidermie en diorama. Saamgelees met Halloran se idee van die teks as argivale ruimte of museum, word hierdie konsepte (naamlik taksonomie, taksidermie en diorama) voorgehou as ‘n leesstrategie waarmee die bewaringsgesinde poësie van Marais gedekodeer kan word.
This research report focuses on the environmental poetry of Johann Lodewyk Marais. His poetry has been described as “green”, “environmental”, “ecopoetical”, “bioregional” and “biogeographical” and critics agree that the oeuvre displays a strong element of conservation and even preservation. Marais’s unique contribution towards this discourse of conservation is assessed by utilising certain key concepts from museology, which frequently manifests in his poetry as metaphors: taxonomy, taxidermy and diorama. Halloran’s notion of the text as archival space or museum, read in tandem with these concepts of taxonomy, taxidermy and diorama, is then presented as a reading strategy for decoding Marais’s poetry.

Full textRepresentatives of the genus Argulus (Crustacea: Branchiura) are ectoparasites of marine, brackish and freshwater fish. A survey of the literature revealed that more than 20 species of the genus are endemic to the African continent. Information on some of the species is extremely meager. Because of a need for a single reference that would present the basic data on the African argulids in a concise and systematic manner, a compendium was compiled of the taxonomic characteristics of all the endemic as well as one alien Argulus species which occur in Africa. The occurrence and distribution of these species are also given. Some discrepancy in terminology was found e.g. in the designation of cephalic appendages, the armature of the carapace, the thoracopods and, in the accessory appendages that are used in copulation. Subsequently, a glossary of technical terms were compiled for the genus Argulus in order that uniform descriptions of morphological structures can be given. Argulid ectoparasites were collected in various impoundments in the Transvaal. All the specimens collected were identified as Argulus japonicus Thiele, 1900. Argulus japonicus affected a broad spectrum of fish hosts. A survey was carried out in Lake Barberspan and Bloemhof Dam in which site selection on hosts was studied and infestation statistics were compiled. The fishlouse A. japonicus is an opportunistic ectoparasite which was probably introduced by introductions of exotic fish. This alien fish parasite was associated with mortalities of rainbow trout, Salmo gairdneri, in an aquaculture system in the Transvaal. A morphological study was carried out on adult, male and female, specimens collected from the Transvaal. This study, the first scanning electron microscopy investigation on any argulid specie as yet, elucidated morphological structures as well as ultrastructures not previously reported.

These characters are discussed and illustrated. Characters of' the genus Glia Sond. were also studied and the genus is shown to be an obvious outgroup in a phylogenetic analysis. Despite the paucity of characters and the variability of character states in the genus Anginon, it is possible to give here a summary of character evolution as interpreted within the genus and also an explicit hypothesis (cladogram) of phylogenetic relationships amongst the species. Especially, the study of the fruit anatomy has resulted in a better understanding of taxonomic relationships at the generic and infrageneric levels. A formal taxonomic treatment is presented, including a key to the species, correct nomenclature, typification, descriptions and distribution maps.

Full textThis archaeozoological study was undertaken to distinguish between the two hare species of South Africa, Lepus capensis (Cape hare) and Lepus saxatilis (scrub hare), from fragmentary archaeological faunal remains. It was previously not possible to taxonomically differentiate between these species. The research focused on Lagomorpha remains previously identified in Later Stone Age assemblages from two rock shelters, Blydefontein and Meerkat, in the Karoo. Analyses of modern skeletal material housed in museum collections demonstrated that there are indeed morphological and morphometric differences between Lepus capensis and Lepus saxatilis. The Lagomorpha material from the two archaeological assemblages were then re-examined utilising the newly established protocols. The reanalyses proved that it is now possible to distinguish between the two hare species even when in fragmentary form. It is also possible to identify Pronolagus. The dietary and likely cultural roles of the Lagomorpha and other small mammals in archaeological contexts are also explored.
Hierdie argeosoölogiese studie is onderneem om te onderskei tussen die twee haasspesies in Suid-Afrika, Lepus capensis (vlakhaas) en Lepus saxatilis (kolhaas), aan die hand van gefragmenteerde argeologiese fauna-oorblyfsels. Dit was nie voorheen moontlik om hierdie spesies taksonomies van mekaar te onderskei nie. Die navorsing fokus op Lagomorpha-oorblyfsels wat voorheen geïdentifiseer is in rotsskuiling-versamelings wat uit die Laat Steentydperk dateer. Die genoemde rotsskuilings is gevind by Blydefontein en Meerkat in die Karoo. Ontledings van moderne skeletmateriaal in museumversamelings het getoon dat daar wel morfologiese en morfometriese verskille tussen Lepus capensis en Lepus saxatilis is. Lagomorpha-materiaal afkomstig van die twee argeologiese versamelings is toe herondersoek aan die hand van nuut gevestigde protokolle. Die herontledings het bewys dat dit nou moontlik is om te onderskei tussen die twee haasspesies, selfs indien hulle gefragmenteerd is. Dit is ook moontlik om Pronolagus te identifiseer. Die rolle wat die Lagomorpha en ander klein soogdiere in argeologiese kontekste in dieet en kultuur vervul het, is ook ondersoek.

Full textThis study explored teachers’ effective use of questioning as a teaching strategy in Social Studies in grade seven within a primary school in the Kingdom of Eswatini (formerly known as Swaziland). The advent of free primary education has brought about large class sizes, but the desire to produce quality education persists. The literature distilled in the study showed that, although a considerable body of studies has established that questioning in the classroom helps direct learning, many teachers fail to utilise it as such. Those who endeavour to use it succeed in engaging their learners, and this results in teaching effectiveness and good outcomes for their learners. The study employed the interpretive paradigm because of the in-depth nature of the investigation. It therefore was a qualitative study that used observation and in-depth semi-structured interviews to gather data and attain the objectives of the study. It was a case study in which four Social Studies teachers took part. Observations were made for at least for 60 minutes in each classroom. Field notes were taken and later analysed. Individual interviews were conducted with the teachers. The results of the study showed that teachers did not use questions to direct teaching and learning, and had no knowledge of the concept of wait time. They also said that they had not been taught questioning strategies in their pre- service teacher training. This was consistent with the literature. Though research shows that questioning promotes effective teaching, the studies reviewed indicated that few teachers use it as an instructional tool. The implications derived from the present study are therefore that pre-service teacher training has to be improved to cater for such important topics as classroom questioning. Also to be improved is further professional development. There is a significant need for action at the macro- and micro-levels of the educational system towards improvement. The actions at the micro-level will be determined by diligent policies designed and executed at that level, that is, the level of the school.
Hierdie studie verken onderwysers se benutting van vraagstelling as onderrigstrategie in Sosiale Studies in Graad 7 by ʼn primêre skool in die koninkryk Eswatini (voorheen Swaziland). In weerwil daarvan dat gratis primêre onderrig groot klasse tot gevolg het, moet gehalteonderwys steeds nagestreef word. Volgens die literatuur wat geraadpleeg is, toon talle studies dat vraagstelling in die klas regstreekse leer bevorder. Onderwysers wat vrae aan leerders stel, gee doeltreffend onderwys omdat hulle leerders betrek, en sodoende ʼn goeie uitkoms behaal. Desondanks pas min onderwysers hierdie strategie toe. Op grond van die aard van hierdie ondersoek, is ʼn vertolkende paradigma gevolg. In hierdie kwalitatiewe studie is data deur waarneming en halfgestruktureerde onderhoude ingesamel. Elke klas is vir minstens 60 minute waargeneem en veldaantekeninge is gemaak wat later ontleed is. Vier onderwysers wat Sosiale Studies onderrig, was deel van die gevallestudie. ʼn Onderhoud is met elkeen gevoer. In hierdie studie is bevind dat die onderwysers geen vrae in die klas gestel het nie. Hulle het ook nie die begrip van wagtyd geken nie, aangesien hulle nooit in vraagstellingstrategieë opgelei is nie. Dit verklaar bevindings in die literatuur dat min onderwysers vraagstelling in die klas gebruik. Vraagstelling moet dus deel van onderwysers se opleiding uitmaak. Hierbenewens moet die professionele ontwikkeling van onderwysers aandag geniet. Voorts is dit noodsaaklik dat die onderwysstelsel op sowel mikro- as makrovlak verbeter word. Ingryping op mikrovlak sal deur die uitvoering van beleid op skoolvlak bepaal word.

Full textVir die een-en-twintigste-eeuse kennisekonomie is intellektuele vaardighede (soos kritiese denke) geïdentifiseer as noodsaaklik vir sukses. Opvoedkundige instellings het 'n verantwoordelikheid om studente met die kennis en vaardighede toe te rus wat nodig is vir toekomstige indiensneming. Die Suid-Afrikaanse Instituut vir Geoktrooieerde Rekenmeesters het kritiese denke geïdentifiseer as 'n vaardigheid wat studente in Finansiële Rekeningkunde, wat geoktrooieerde rekenmeesters wil word, moet ontwikkel. Vir hierdie verhandeling van beperkte omvang, is 'n kwalitatiewe studie gedoen deur 'n konstruktivistiese paradigma toe te pas op 'n gevallestudie-ontwerp om die ontwikkeling van kritiese denke in eerstejaarstudente in Finansiële Rekeningkunde in 'n oop e-afstandsleerkonteks in Suid-Afrika te ondersoek. Om hierdie doel te bereik, is data versamel deur semi-gestruktureerde onderhoude te voer met twaalf akademici en dokumentontleding te gebruik. Omdat die studie beperk was tot twee eerstejaar finansiële rekeningkunde modules, wat deel vorm van die Suid-Afrikaanse Instituut vir Geoktrooieerde Rekenmeesters se geakkrediteerde program wat by 'n oop e-afstandsleerinstelling aangebied word, kan die bevindinge nie veralgemeen word nie. Alhoewel die studente se persepsies nie in die studie in ag geneem is nie, bied die bevindings waardevolle insig oor die ontwikkeling van kritiese denke in rekeningkundemodules. Die bevindings dui daarop dat, alhoewel akademici glo dat vaardighede in kritiese denke en goeie denkgewoontes in die eerste jaar van Finansiële Rekeningkunde onderrig moet word, word dit tans slegs deur 'n inhoudgebaseerde benadering gedoen, of glad nie. Verder word slegs tegnologieë geïnkorporeer waarmee akademici gemaklik is, hoofsaaklik vir die oordrag van die inhoud. Die aanbevelings vir kurrikulumevaluering en professionele ontwikkeling hou spesifiek verband met hierdie bevindings.
