Abstract:

A set of 15 accessions of maca, Lepidium meyenii Walp., and 25 accessions of yacon, Smallanthus sonchifolius (Poepp. &amp; Endl.) H. Robins., cultivated under Czech field conditions was studied to determine relationships between morphological variability and isozyme polymorphisms. Morphological characterisation of maca included evaluation of length, weight, shape, skin and flesh colour of hypocotyls. In yacon, we evaluated shape, colour, skin texture and flesh colour of tubers, as well as the number of roots. Preliminary results showed that maca forms low-weight hypocotyls (up to only 17.4 g) under Czech field conditions. For yacon, tuber production ranged between 1.4 kg and 3.8 kg. Of the 17 analysed enzymatic systems, only esterase (EST) showed some degree of polymorphism in both crops. It was possible to divide accessions of L. meyenii into two groups and S. sonchifolius into six groups on the basis of isozyme polymorphisms. However, EST polymorphisms do not correspond very well to the morphological characteristics of the underground organs of the crops studied. &nbsp;

ABSTRACT. Variation of specific morphological traits and ploidy level of five Aegilops L. species in Morocco.The genus Aegilops L. represents an important natural source of useful genes for wheat breeding, with particular emphasis on biotic and abiotic stress resistance. For successful crosses, the primarily step is to select appropriate Aegilops accessions. In this paper, we studied five Moroccan species of an Aegilops collection on the basis of spike structure and chromosome number. Twenty-eight specific morphological characters were used to differentiate the species. Statistical analyses, in particular the DFA, allowed the characterization of the genetic variability of the species; the two first standardized axes explained 96,2% of the total variability and 100% of the entities were classified within their own group. In addition, the dendrogram constructed using morphological data reveals a significant variability within and between species. Cytogenetic study revealed four species, A. geniculata Roth, A. triuncialis L., A. ventricosa Tausch and A.peregrina Maire & Weiller, to be tetraploid. However, A. neglecta Req. ex. Bertol., where only two accessions are represented in the collection, revealed to be hexaploid, and can then be classified as A. neglecta subsp. recta Chennav.Key words. Aegilops, Variation, Morphology, Ploidy, Morocco.RÉSUMÉ. Variation des caracteres morphologiques specificities et niveau de plordie de an(' espéces Aegilops L. au Maroc. Le genre Aegilops L. représente une importante source de genes, potentiellement utilisables dans Pamelioration des blés cultivés (Triticum spp.) notamment pour la resistance aux stress biotiques et abiotiques. Le choix des accessions Aegilops á employer, dans un programme d' hybridation interspécifique, necessite une caractérisation taxonomique et une evaluation préalables. L'objectif de ce travail a ete d'étudier des accessions, appartenant á 5 especes marocaines constituant une collection d'Aegilops, sur la base de caracteres morphologiques specifiques de l'épi et du niveau de ploYdie. La caractérisation phénotypique a été basée sur l'étude de 28 caracteres morphologiques qui discriminent entre les especes. Les resultats des analyses statistiques, en particulier de l'AFD, ont permis de caractériser la variabilite génetique de ces especes et ant donne un pourcentage d'appartenance á l'espece de 100%. Aussi, les deux premiers axes standardises expliquent 96,2% de la variabilité totale. Un demlrogramme a éte aussi construit, revelant une variabilite interspecifique. L'étude cytogenétique a révélé une tetraploYdie pour A. geniculata Roth, A. triuncialis L., A. ventricosa Tausch et A. peregrina Maire & Weiller. Quant á A. neglecta Req. ex. Bertol., une hexaploYdie a été mise en evidence pour les deux uniques accessions disponibles dans la collection, permettant de leur attribuer le nom A. neglecta subsp. recta Chennav.Mots clés.

Abstract:

This study evaluates the morphological concept of Crepidotus variabilis and similar taxa based on basidiospore and cheilocystidia characters. A phylogenetic analysis of the ITS region clearly distinguished C. variabilis var. variabilis from the two other distinct taxa of the same lineage, C. variabilis var. trichocystis and C. neotrichocystis. We also recognised one additional morphologically similar and undescribed species that belongs to the C. variabilis lineage. All four taxa can also be recognised morphologically using basidiospore and cheilocystidia characters. Our detailed statistical comparison of these characters improves the knowledge of their variability and specifies more precisely the morphological circumscription of the taxa within this group.

Abstract:

The widespread occurrence and local abundance of corbulid bivalves in Neogene deposits of the northern Dominican Republic provide an opportunity to evaluate physical controls on species distributions and intraspecific variability in this group. First and last appearances of species probably do not record speciation and extinction, but instead represent migrations into and out of the study area, and reflect corbulids' preference for marginal-marine and shallow-marine conditions. Corbula cercadica and C. viminea show patterns of intraspecific morphologic variability over time and space. Corbula cercadica shows continuous morphologic variability along a paleoenvironmental gradient of salinity, depth, and bioclastic fabric, whereas variation in C. viminea is morphologically clinal from west to east in roughly contemporaneous sediments, with variability related to sediment type and bioclastic fabric. Ecophenotypic variation or genetic differences, rather than taphonomic processes, seem to control geographic variability within C. cercadica and C. viminea. Although it is not possible to determine whether intraspecific morphologic variability was under genetic control, its stronger relationship with paleoenvironmental conditions relative to stratigraphic position suggests lack of anagenetic morphological evolution.

Abstract:

Opium poppy (Papaver somniferum L.) is currently an important agricultural commodity, with the product being used in the food industry (seed) as well as in the pharmaceutical industry (morphine and other alkaloids). Intensive production of poppy leads to a specific direction of breeding with the aim to obtain highly productive cultivars of the so-called food industry or industrial type. The paper evaluates 57 genetic resources (mostly cultivars), comparing the groups of values representing the indicators of production-significant morphologic and agricultural characters (capsule size; morphine content in poppy straw; weight of dry, empty capsule) and content of morphine in the poppy straw, in relation to the ideotype of poppy, which in these indicators represents 100% of the value. On average lower values in the above indicators were achieved by cultivars with white-coloured seed, including morphine content; concrete data are specified in three cultivars with morphine content in the poppy straw above 0.40%. In blue-seed to grey-seed cultivars, except for the high-morphine cultivar Buddha (1.85% of morphine), we found only six materials with a minimum morphine content of 0.8% in the poppy straw (maximum of 0.92%). These genetic resources also achieved very good values in the morphological indicator and average value in the economic indicator. The results will be used in the selection and classification of suitable genetic resources of poppy in breeding of industrial forms.

Full text

Abstract:

Abstract Key accounts of morphological variability in L2 acquisition posit either deficits in the representation of abstract morphosyntactic features or the mapping between morpho-phonological forms and syntactic features due to computational limitations. This study extends previous research to L2 Italian, a richly inflected language. The production and grammatical intuitions of suppletive and affixal verb inflection were elicited from a cross-section of instructed adult L2 learners with L1 Spanish and L1 English. Although a clear production-intuition gap was found, supporting computational views, a strong regularity in the degree of variability across test conditions, L1s, and proficiency levels was also attested, supporting representational accounts. The findings suggest morphological development in L2 Italian is consistent with structure-building models that assume no L1 transfer of functional features. Imperative verb forms in L2 Italian are proposed as defaults equivalent to the bare verb forms of L2 English and non-finite defaults of L2 French and German.

Abstract:

Fifty one accessions of nineteen Lactuca species, the hybrid L. serriola &times; L. sativa and the related species Mycelis muralis were evaluated for morphological variability, esterase (EST) polymorphism, Amplified Fragment Length Polymorphism (AFLP) and relative DNA content. Sixteen Lactuca accessions were classified taxonomically on the basis of morphology, isozyme analysis and AFLP. Twenty-eight bands (isoforms) of EST were recorded allowing 82% of accessions to be distinguished. The relative DNA content, measured using flow-cytometry (DAPI staining), ranged from 2.02 pg in L. capensis to 17.96 pg in L. canadensis. The results from AFLP analysis and the relative DNA content measurement corresponded well with recent taxonomic classification of the genus Lactuca. &nbsp;

Abstract:

The aim of this work was to suggest a reliable method for distinguishing between diploid and tetraploid taxa of the genus Betula Linnaeus, based on leaf measurements. In total, 97 individuals from 6 locations within the Bohemian Forest region (Czech Republic) were selected. Four leaves from each individual were evaluated. On each leaf, twenty parameters were measured. Each sample was analysed by flow cytometry to determine its actual ploidy. Measured parameters were analysed by principal component analysis and tested for differences between diploid and tetraploid taxa. For actual ploidy prediction, a classification function was designed. The reliability of the classification function was verified on samples from three different regions of the Czech Republic and compared with functions as suggested by other authors. The classification function designed in this work (based on 3 parameters – blade width in the upper 1/4 of blade length, first vein angle and number of leaf teeth between 3<sup>rd</sup> and 4<sup>th</sup> vein) correctly determined actual ploidy in 89% of all tested samples.

Abstract:

Whorled clary was chosen as one of the medicinal plants with prospects for the reconstruction of flowering meadows in some areas of the Czech Republic. Nevertheless, production of uniform seed mixtures for these purposes brings a risk of decreasing the natural biodiversity of such meadow phytocenoses; and therefore the variability of its morphological characteristics and the content of essential oil in individual populations of this genus in the Czech Republic were studied. Among the studied populations, statistically significant differences in morphological characters were found, but not in the contents of the essential oil.

Abstract:

Recent literature in second language acquisition shows that syntax-driven structures give way to successful modal interpretation and morphological production, while discourse-dependent environments do not (Sorace, 2005; Tsimpli & Sorace, 2006, Borganovo, Bruhn de Garavito, & Prévost, 2008; Iverson, Kempchinsky, & Rothman, 2008). It has also been suggested that discourse-dependent environments involve both structural and pragmatic knowledge of L2, which intersect at the syntax-discourse interface (Sorace, 2005; Iverson, Kempchinsky, & Rothman, 2008), thereby requiring a multi-layered understanding of the target language. The present study contributes to this line of research by further examining morphological variability (Prévost & White, 2000; Sorace, 2000; Sorace, 2005; Iverson, Kempchinsky, & Rothman, 2008; Slabakova, 2009) in L2 acquisition at the morphosyntactic-semantic interface, following the work of Borganovo, Bruhn de Garavito, & Prévost (2008). The results of our study reveal that learners, even at advanced stages of acquisition, perform poorly in epistemic environments where syntax and discourse intersect. In such environments, there appears to be an interaction with pragmatics (cf. Iverson, Kempchinsky, & Rothman, 2008) that causes learners to opt for the indicative mood, even when the subjunctive is prescriptively required. Unlike deontic modality, which is essentially syntax-driven, epistemic modality requires structural knowledge, as well as knowledge from other domains (Sorace, 2005). Our study reveals that learners at all levels of instruction performed better in “purely syntactic” environments of deontic modality than in pragmatically challenging epistemic environments.

Abstract:

Unique morphologies can enable bacteria to survive in their native environment. Furthermore, many bacteria change their cell shape to adapt to different environmental conditions. For instance, some bacteria increase their surface area under carbon or nitrogen starvation. Bacteriodes thetaiotaomicron is an abundant human gut species; it efficiently degrades a number of carbohydrates and also supports the growth of other bacteria by breaking down complex polysaccharides. The gut provides a variable environment as nutrient availability is subject to the diet and health of the host, yet how gut bacteria adapt and change their morphologies under different nutrient conditions has not been studied. Here, for the first time, we report an elongated B. thetaiotaomicron morphology under sugar-limited conditions using live-cell imaging; this elongated morphology is enhanced in the presence of sodium bicarbonate. Similarly, we also observed that sodium bicarbonate produces an elongated-length phenotype in another Gram-negative gut bacterium, Escherichia coli . The increase in cell length might provide an adaptive advantage for cells to survive under nutrient-limited conditions.

Abstract:

Abstract The subject of our research was Trifolium repens L. The aim was to assess the level of morphological and anatomical variability among populations from different habitats (meadows, roadsides, subalpine slopes) and different altitudes (891–1881 m) in Brezovica (Sharri Mountain, Kosovo). The investigation covered 26 morphological and anatomical traits in populations from 12 locations. From the results obtained during this research, it can be concluded that there is a significant difference among populations for most micro- and macro-morphological traits. There is also a tendency towards a reduction of most of the average values of the investigated parameters (total plant height, total leaf length, leaf petiole length, peduncle length, fruit weight, number of flowers in an inflorescence, stomata length on the upper leaf surface, and diameter of collateral bundle) in relation to altitude increase. However, trichome length showed consistency and was not affected by habitat and altitude changes. The results also lead to a proposal for taxonomic revision of this taxon.

Abstract:

Abstract. River restoration can enhance river dynamics, environmental heterogeneity and biodiversity, but the underlying processes governing the dynamic changes need to be understood to ensure that restoration projects meet their goals, and adverse effects are prevented. In particular, we need to comprehend how hydromorphological variability quantitatively relates to ecosystem functioning and services, biodiversity as well as ground- and surface water quality in restored river corridors. This involves (i) physical processes and structural properties, determining erosion and sedimentation, as well as solute and heat transport behavior in surface water and within the subsurface; (ii) biogeochemical processes and characteristics, including the turnover of nutrients and natural water constituents; and (iii) ecological processes and indicators related to biodiversity and ecological functioning. All these aspects are interlinked, requiring an interdisciplinary investigation approach. Here, we present an overview of the recently completed RECORD (REstored CORridor Dynamics) project in which we combined physical, chemical, and biological observations with modeling at a restored river corridor of the perialpine Thur River in Switzerland. Our results show that river restoration, beyond inducing morphologic changes that reshape the river bed and banks, triggered complex spatial patterns of bank infiltration, and affected habitat type, biotic communities and biogeochemical processes. We adopted an interdisciplinary approach of monitoring the continuing changes due to restoration measures to address the following questions: How stable is the morphological variability established by restoration? Does morphological variability guarantee an improvement in biodiversity? How does morphological variability affect biogeochemical transformations in the river corridor? What are some potential adverse effects of river restoration? How is river restoration influenced by catchment-scale hydraulics and which feedbacks exist on the large scale? Beyond summarizing the major results of individual studies within the project, we show that these overarching questions could only be addressed in an interdisciplinary framework.

Abstract:

This paper presents the results of a study dealing with leaf morphological variability of Quercus robur L. 148 trees were sampled from 5 population across Serbia and 17 morphological traits were assessed. Interpopulation variability was confirmed by the results of the analysis of variance (ANOVA). A statistically significant (p <0.05) effect of population was obtained for most of the studied morphological characters. Intrapopulation variability was confirmed by statistically significant tree effects for all of the studied leaf characters (all p < 0.05). The results of the multivariate analysis of variance (MANOVA) confirmed a significant population and tree share in the total phenotypic variability (all p <0.05). By applying the canonical discriminant analysis (CDA), the first discriminant function accounted for 63% of the variability between populations and the second accounted for 20% of the population variability. The leaf area (AREA), specific leaf area (SLA) and surface area to perimeter ratio (ARPE) had the greatest effect on population differentiation (CDA). It is assumed that different environmental conditions affect population differentiation and that high intrapopulation variability is due to intraspecific variability.

Abstract:

The research describes the field comparison of 81 decorative sunflower genotypes. In order to assess genetic diversity of sunflower genotypes the studies were conducted in the field conditions during 2010-2015 at the Institute of Field and Crops, Novi Sad, Serbia. The genetic diversity of species Helianthus annuus L. has enabled the breeding work in the direction of the decorating and plant landscaping. Depending on the qualitative and quantitative characteristics, production of decorative sunflowers can be divided into three directions. The first line is for the production of cut flowers, the second one is for garden production and the third line is for the production of pot plants. The direction of production dictates the main breeding objectives, which may include: plant architecture, the color of ray and disc flowers and duration of flowering. Investigation of the genetic variability of ornamental sunflowers relies on quantitative traits of which the greatest variability was observed in branching and plant height, which are also the most important qualities for production. The quantitative characteristics of decorative sunflowers have been examined on the basis of 81samples.
