Abstract:

With rapid economic and social development in Tianjin coastal area, environmental impact factors are increasingly complex. In order to study the relationships between macrobenthos and environmental variables, macrobenthos and seven environmental variables (including dissolved oxygen, active phosphate, inorganic nitrogen, ammonia, nitrate, nitrite, and oil) are investigated in the summer of 2004 and 2007. Canonical Correspondence Analysis (CCA) and Redundancy Analysis (RDA) in CANOCO software are all employed in the analysis for mutual authentication of the result. The results indicate that: (1) reactive phosphate and nitrite are the most important impact factor for the macrobenthic community; (2) nitrate is the supplementary factor that explains the macrobenthos data; (3) whether inorganic nitrogen is a key impact factor, it needs further research.

Abstract:

Biotic and abiotic heterogeneity in spatial and temporal scales were characterized for two areas of the xerophytic shrubland of the “Pedregal de San Ángel” (REPSA) ecological reserve. Nine floristic groups were identified and they showed a differential distribution of the plant species that inhabit this community. Each one of the groups was named according to the key species, therefore they were considered as determinants in the communities physiognomy. Through the use of multivariate analysis (TWINSPAN and CANOCO) we observed that species composition in the groups is modified in spatial and temporal scales. This study suggests that variation of some abiotic factors such as soil depth and slope influences differentially the systems heterogeneity. Temporal heterogeneity was evident since there was a different floristic composition in this area during the dry and the rainy season.

Abstract:

The ionic content was examined in nine aqueous tea extracts in which time of boiling, acidification of the medium using lemon juice and way of preparation were observed as factors. Ion chromatography was used for determination of inorganic anion content, and data were processed using CANOCO program for multivariate analysis. The variations in ionic content were observed among different tea samples. The highest concentrations of chloride, nitrate, phosphate, and sulphate ions were found in nettle, while the highest concentrations of fluorides were detected in elderflower tea infusion. The effect of boiling time (5, 10, and 20 min), acidification of the medium and different preparation procedure (boiling and cooling at room temperature) were statistically presented using principal component analysis. The examined factors did not have a significant effect on the ionic concentration in tea infusions.

Abstract:

Multivariate analysis using two-way indicator species analysis (TWINSPAN) and Canonical correspondence analysis (CCA) were used to classify the phytosociology of the District Vehari, Pakistan. A total of 35 plant species belonging to 23 families were recorded. The first level TWINSPAN divided the vegetation of entire study area into two major communities which were subsequently separated into subcommunities. Each major and sub-community was named following the most important dominant species. CCA identified the relationship of vegetation structure to specific environmental factors. This relationship was studied by CANOCO analysis. In the CCA of all the species for Vehari, soil pH and water pH and EC were the most important variables influencing the species distribution. This survey offers key information regarding vegetation and would be helpful for the conservation of biodiversity of the area under study.

Abstract:

AbstractThis study was carried out to determine the plant communities and understand the main topographical driving factors of floristic differentiation in the Sivrihisar Mountains (Eskişehir Province). Vegetation samplings were carried out according to the Braun-Blanquet approach. The relevés were stored in the TURBOVEG database management program. Hierarchical classification was carried out in PC-ORD program with Ward’s method and Euclidean distance as a resemblance measure. The diagnostic species were identified by a fidelity measure in the JUICE program. The results of the classification were visualized by ordination techniques in the CANOCO package by using principal component analysis. In conclusion, except for the degraded forest community, all the 7 steppe and 1 scrub plant communities studied were identified and described as new associations. Also, a syntaxonomical scheme for the vegetation of Sivrihisar Mountains was suggested.

Abstract:

Macroinvertebrate communities and environmental variables were assessed in an Ankara Stream receiving high organic and industrial wastes. Environmental data were used to explain biological variation using multivariate techniques provided by the program CANOCO. The ordination method CCA (Canonical Correspondence Analysis) was applied to evaluate the relationships between environmental variables and distribution of macroinvertebrate genera. Data sets were classified by TWINSPAN (Two Way Indicator Species Analysis). In this investigation, macroinvertebrate communities have been shown by CCA ordination to be related to TOM (total organic matter), ammonia, cadmium, pH, lead, dissolved oxygen, conductivity (EC), phosphate, boron, nitrite and hardness, with TOM, ammonia, cadmium and pH emerging as the most significant environmental variables. Epeorus was a TWINSPAN indicator for the slightly polluted upstream site 1. Physa was a TWINSPAN indicator for the polluted downstream sites.

Abstract:

The protected areas are worth great in vegetation conservation; this supported their interest in scientific research on the tools being able to be used for their sustainable management. The present study enters within the framework of a better knowledge of Comoé-Léraba reserve plants communities’ and the soils conditions which explained their distribution, in the aim to make better decisions for it conservation. The objective of the survey is to discriminate the plants communities in relation to soils’ physicals and chemicals parameters which control their distribution. Thus, 368 physociological plots have been done in the field by applying Braun-Blanquet (1932) method and then the plants communities’ package has been carried out in CANOCO software. In related to each ecosystem, 11 plants communities’ have been clearly defined, according the phytosociological statements (DCA). Among these communities four news syntaxons were determined based on previous studies in the same phytogeographical zones. Then their direct ordination (CCA) with soil’s (physical and chemical) parameters, shows that plants communities’ distribution is governed mainly by the water regulation on the ground and also its texture. The obtained results will certainly contribute to lay down a constant policy maker in biodiversity conservation. Lieux de refuge et de conservation de la végétation, les aires protégées sont des zones potentiellement diversifiées. Elles suscitent un grand intérêt pour la recherche en vue de découvrir des outils pouvant servir à leur gestion durable. La présente étude entre dans le cadre d’une meilleure connaissance des communautés végétales de la réserve de la Comoé-Léraba et des conditions édaphiques qui sous-tendent leur installation en vue de faciliter les prises de décisions entrant dans le cadre de sa conservation. Ainsi, l’objectif était de discriminer les groupements végétaux en relation avec les paramètres édaphiques qui gouvernent leur distribution. Sur le terrain, 368 relevés physociologiques ont été réalisés en appliquant la méthode de Braun Blanquet (1932) et l’individualisation des groupements végétaux a été réalisée grâce au logiciel CANOCO. L’analyse a permis de discriminer 11 groupements végétaux dont la classification syntaxonomique révèle quatre nouveaux taxons comparativement aux études réalisées dans les zones phytogéographiques similaires. L’ordination directe (CCA) intégrant les paramètres physiques et chimiques des sols, permet de considérer la texture et les paramètres hydriques des sols comme étant les plus efficients dans la distribution des groupements végétaux. Les résultats obtenus contribueront certainement à définir une politique soutenue de la conservation de la biodiversité.

Abstract:

AbstractThe ecological drivers of macrophyte development in a lowland agricultural area were tested based on a 2008 survey on the Wkra River catchment. Our survey was carried out in the rivers of an agricultural area with relatively high concentrations of both nitrates and phosphates in the water. By using the Polish macrophyte method, we were able to calculate several botanical metrics. Canonical ordination analyses used to relate biological data to environmental variables such as physical and chemical parameters of water, surface water velocity or river width, were carried out using CANOCO for Windows. Redundancy analysis (RDA) showed that pH and alkalinity were the parameters best correlated with the distribution of macrophytes and values of macrophyte indices. The recorded values of the Macrophyte Index for River in the Wkra River and its tributaries reflected their good and moderate ecological status (the Water Framework Directive scale). Despite the fact that nutrient concentrations in the water were relatively high and that most of the sites represented eutrophic conditions, the results of this survey showed that non-nutrient parameters may play an important role in explaining aquatic plant occurrence in rivers that have been subjected to eutrophication.

Abstract:

Myriophyllum spicatum distribution in Al-Burgga marsh, Hor Al-Hammar was described in relation to some of the physical-chemical properties for its habitat (water depth, light penetration, water temperature, water salinity, pH, dissolved oxygen, Ca+2, Mg+2, reactive NO2=, reactive NO3-1, and reactive PO4-3) during 2011, seasonally. CANOCO ordination program (CCA) was used to analyse the data. Its vegetation cover percentage was with its peak at summer, its value was 90 %, while the lowest value was 20 % in winter. Statistically, Positive relationships for WT, sal., Ca+2, Mg+2, reactive NO2=, reactive NO3-1, and reactive PO4-3 with the vegetation cover percentage were observed. While, negative relationships for WD, pH, and DO with the vegetation cover percentage were observed. Also, the negative relationship between light penetration and the vegetation cover percentage can be attributed to the water depth, which was shallow and the light penetration followed water depth and reached to the bottom during all of the period study. In addition, two species were registered with Myriophyllum spicatum community as associated species, which are Hydrilla verticillata and Ceratophyllum demersum.

Abstract:

A vegetation survey was undertaken of the 49 000 ha Songimvelo Game Reserve in the Barberton Mountainland of Mpumalanga. South Africa with the aim to identify constituent plant communities and to assess their relative value to wild herbivores. The vegetation is highly diverse with representation of three biomes: Savanna. Grassland and Forest A total of 428 plots were sampled by means of a semi-quantitative technique. Data were subjected to ordination (CANOCO) and classification (PATN). The composition of the 19 distinct communities is determined through an intricate combination of environmental factors as evident from the ordination results. Firstly drainage line' position is critical, followed by land use history and further by the interplay between elevation and geology. These findings are in line with results obtained from other studies along the eastern Escarpment. Alluvium, mafic and ultramafic lavas support mixed veld, whereas felsic lavas, sandstones and quartzites support sour veld which has a very low forage value in the dry’ season. Each community, through its specific species assemblage, structure and location, forms a distinctly different habitat in terms of its value to the various species of herbivores in the SGR

Abstract:

AbstractA total of 437 species (453 with infraspecific taxa) of algae and Cyanobacteria were identified in 2034 samples collected during the first research on nine thermokarst lakes in Yakutia carried out in 1986–1994 and 2001–2015. The richest algal flora was determined in Lake Aalah, represented by 241 taxa. Bacillariophyta species dominated in four lakes, whereas Chlorophyta and Cyanobacteria dominated in the others. The algal bioindication demonstrated preferences for benthic and plankticbenthic life, temperate temperature, low alkalinity, waters with moderate oxygenation, low to medium enrichment with chloride, low organic pollution, and mesotrophic state. Comparative floristic, CANOCO and JASP statistical methods divided the species and environmental variables into groups of lakes related to landscape terraces. Local landscape positions and high summer water temperatures may play a major role in the formation of algal flora. The index of algae taxa per area stabilized at about 70 species per km2. The highest polymorphism of algae floras, defined by the Subspecies/Species Index, was determined for the lakes of the Tungulunskaya terrace: Lake Ynakh, Lake Nal Tungulu and Lake Tungulu (1.041–1.058), and the average total flora was 1.036. Our results can help in monitoring and protecting the ecosystems of thermokarst lakes in Yakutia in the harsh climate environment of Northeastern Eurasia.

Abstract:

This paper focuses on the type of cover and preserving agent influence on composition of entrapped fauna of Carabidae beetles. The research took place in the northern part of the protected landscape area of Žďárské vrchy, south from Kameničky municipality in rural district of Chrudim. Epigeic fauna was monitored one month from April 30th to June 5th 2008 – in the period of the highest activity of most Carabidae species. Traps were located in Latin square with five meter distance, using three preserving agents (formaldehyde, ethylene glycol, sodium chloride solution) and three types of covers above pitfall traps (acrylic glass cover, no cover, or wooden board put above the trap). Within the research 1123 Carabidae specimens belonging to 21 species were entrapped. The most numerous was Poecilus cupreus (915 specimens) in which also the strongest relationship to formaldehyde was detected. The redundancy analysis (RDA) from CANOCO package was used for statistical evaluation. With monitored variables, a significant influence (T = 0.137, F = 3.020, P = 0.0240) of formaldehyde on presence of some Carabidae species was confirmed (Poecilus cupreus, Amara lunicollis, Pterostichus diligens, and Bembidion guttula). Influence of the cover above the pitfall trap on species range in the trap was not confirmed (T = 0.062, F = 2.574, P = 0.0710).

Abstract:

The set of 7 flowering plant species (Anethum graveolens, Calendula officinalis, Centaurea cyanus, Fagopyrum esculentum, Foeniculum vulgare, Tagetes patula and Vicia faba) was compared for their attractiveness to natural enemies such as ladybeetles (Coccinellidae), hoverflies (Syrphidae), ichneumon wasps (Ichneumonidae) and predatory bugs (Orius spp.) during the years 2008–2010. The trial was held in an organic open field located at the Faculty of Horticulture of Mendel University in Brno, Lednice, Czech Republic. The software Canoco (RDA analysis) was used in order to see the relations between plant and insect communities. Flowering plants A. graveolens, C. cyanus, C. officinalis, F. vulgare and F. esculentum were found to be the most attractive for the evaluated beneficial insects. The most abundant beneficial insects were hoverflies (562008, 1542009, 13242010) and ladybeetles (652008, 1162009, 5112010) followed by predatory bugs (142008, 472009, 1382010) and ichneumon wasps (202008, 142009, 822010).

Abstract:

Burrow wall sediment (BWS) and chamber debris (CD) of Pestarella tyrrhena burrows were isolated and compared to surrounding sediments differentiated into surface sediment (SS), deep ambient sediment (DAS) and embedded ambient organic debris (EAD). The focus was on the meiofauna community along with granulometric characteristics including organic content (OC) and bacterial abundances.Clear trends were found for all parameters: the shrimp significantly increased OC within its burrow and affected grain size distributions. The oxidized burrow walls were highly consolidated, consisted of poorly sorted sediment enriched with silt and clay, and contained small particles of macrophyte debris, while coarse inorganic and organic particles >500 μm were concentrated in the CD. Bacterial abundances (epifluorescence microscopy direct counts, SYBR Gold staining) were positively correlated with OC and were significantly higher in BWS than in SS or DAS. Nematode numbers were elevated three-fold and foraminiferal densities by two orders of magnitude in BWS versus non-burrow sediments. Among the anoxic sediments (DAS, EAD, CD) meiofauna densities in CD were highest. Nematode community analysis (PCA, CANOCO) revealed considerable differences between BWS and SS. The BWS harboured more taxa and was dominated by deposit feeders, while in SS epistrate feeders prevailed.These effects on different levels demonstrate the ability of P. tyrrhena to create a specific microenvironment within the burrow. The burrow walls were most influenced by the shrimp's activity, which corresponds to their nutritional role.

Abstract:

Sites at 244 locations along the west and north Norwegian coasts were investigated to evaluate whether kelp (Laminaria hyperborea) beds had been overgrazed by the sea urchins Strongylocentrotus droebachiensis and Echinus esculentus in the years 1981-1992. Barren ground communities were found in sheltered and moderately wave-exposed areas mainly in the inner and middle archipelago from Nordmøre (63°N) northwards. Densities of large-sized (adult and intermediate) L. hyperborea were 20.7 individuals ·m-2 in kelp beds and 9.7 individuals ·m-2 in transition areas. Juvenile Laminaria spp. were present at densities of 23.9 individuals ·m-2 in kelp beds, 3.6 individuals ·m-2 in transition areas, 0.0 individuals ·m-2 in barren grounds, and 59.1 individuals ·m-2 in kelp-harvested locations. Both the densities and the mean size of S. droebachiensis in barren grounds decreased northwards. The mean densities were 52.2 and 26.1 individuals ·m-2 for the areas south and north of the Arctic Circle, respectively. Multivariate analysis (CANOCO) showed that seven ``environmental'' factors (i.e., kelp depth gradient, distance (latitude), time of sampling, nematode infection in S. droebachiensis, wave exposure, coastal gradient, and substratum) contributed significantly to variability in the distribution of kelp beds and barren grounds. Species in hard-bottom communities in shallow waters could be divided into three distinct BIOTA.

Abstract:

The Andean grassland ecosystems undergo natural and anthropogenic degradation processes. The change of land use for agricultural use is the greatest threat, with a great loss of biodiversity followed by a very slow process of revegetalization. The objective was to assess the richness, abundance and diversity, alpha and beta, in areas of two-, three-, five-, six- and eight years of post-harvest abandonment of Lepidium meyenni Walpers. Ten affected areas were selected for agrostological evaluation, through four linear transects of interception points with 100 records each, applied on the edge and inside the affected area, inside and outside the affected areas, as well as samples composed of soils for each area. Composite soil samples were collected from each transect and study area to analyze their physical and chemical properties. The data were analyzed using the generalized linear mixed model with Rstudio v 5.3.2, and the multivariate analysis of canonical correspondence between biological and environmental variables, using CANOCO v.1.4 software. A significant difference was found between floral composition and alpha diversity according to abandonment time and seasonal periods. The greatest richness and abundance was observed between five- and eight years of abandonment, due to the greater presence of perennial species. Linear correspondence of alpha richness and diversity with organic matter, nitrogen, soil phosphorus and abandonment time was observed.

Abstract:

Se presenta un estudio sobre la composición florística, clasificación fitosociológica, ecología y bioclimatología de las comunidades vegetales de los ambientes desérticos en las cuencas de los ríos Tambo y Moquegua en el Departamento de Moquegua, ubicado al sur de Perú a una altitud que varía entre los 1350 y 3200 m s.n.m. Se realizaron 94 levantamientos fitosociológicos en campo siguiendo la metodología de Braun-Blanquet adaptada por Montesinos, se aplicaron los softwares TWINSPAN 2.3 para clasificar la vegetación y CANOCO 4.5 para el análisis de DCA con variables ambientales. En la clasificación bioclimática se siguió la metodología de Rivas-Martínez. Como resultados se registran 181 especies de flora, de las cuales 32 son endémicas y 121 son nativas. El análisis y clasificación de la vegetación dan como resultado la descripción de tres asociaciones, 5 subasociaciones nuevas y dos comunidades dentro de la nueva alianza Ambrosio artemisioidis-Weberbauerocerion torataensis perteneciente al orden Oreocereo leucotrichi-Neoraimondietalia arequipensis y clase Opuntietea sphaericae. Se halló dos pisos bioclimáticos tropicales: Termotropical y Mesotropical en combinación con cuatro niveles de humedad u ombroclimas: Ultrahiperárido, Hiperárido, Árido y Seco. La vegetación de los ambientes áridos al sur de Perú puede llegar a ser muy variada y restringida a sus cuencas hidrográficas, siendo dependientes de condiciones húmedas extraordinarias que permiten deducir la importancia de conservar estos ecosistemas desérticos.

Abstract:

Hoya is a tropical flowering plant that has great potential as an export commodity. It needs to be cultivated to ensure its sustainability in nature. Information about the suitable habitat of Hoya was not widely known yet. This study aimed to compare the habitat characteristics of several species of Hoya. The research was conducted by exploring the sample plots determined by purposive sampling based on the differences of habitat characteristics. The biotic components observed were phorophyte species type and the number of individual of each Hoya species. The abiotic components measured in each plot were altitude and geographical position, air temperature, humidity, light intensity, wind speed, and canopy cover. Hoya ‘s diversity was analyzed using the Shannon Winner Index. Environmental factor data and biotic factors were analyzed with Canoco for Windows 4.5 software. There were 6 species of Hoya namely Hoya multiflora, Hoya imperialis, Hoya vitellinoides, Hoya hasseltii, Hoya campanulata and Hoya lacunosa found in this study. The highest biodiversity index was obtained in an altitude of 700-800 m.a.s.l (H’=1.41) and in hillsides area (H’=1.3). Hoya ‘s most frequent phorophyte was Schima wallichii. Factors affecting the presence of Hoya in the phorophytes were the position of attachment to the main stem and the rough surface characteristics of the tree. Hoya ‘s preference place was on the bark fracture. Abiotic factors that most influencing the existence of Hoya were air humidity and canopy cover. The data of this research can be used as basic information for carried out the conservation efforts and cultivation strategy in the future.

Abstract:

This paper considers the results of the ordination analysis of weed communities in two regions - the Leningrad Region (LR) and the Republic of Bashkortostan (RB). The dataset includes 1726 relevs of the weed communities executed by the authors during 2000-2018 in cereal and root crops. The calculation of the ecological statuses of communities on 9 scales of D.N. Tsyganov is carried out for ecological characteristics of habitats. The values of the scales corresponding to climatic factors (thermoclimatic scale, cryoclimatic scale, aridity-gumidity scale), edafic factors (salt regime, soil acidity, nitrogen richness, variability of moistening) as well as scales of soil moisture and lightning are attracted to the analysis. The communities ranges on each scale are determined. The detrended correspondent analysis (DCA-ordination) with CANOCO 4.5 software package is used for the identification of ecological patterns of species and communities distribution and definition of the main drivers. It is demonstrated that the sets of the scales reflecting main ecological drivers significantly differ for the compared regions. Only the thermoclimatic scale and the scale of variability of moistening are common for both regions. The scales of nitrogen richness, variability of moistening and cryoclimatic influence generally on floristic composition differentiation in the LR. The scales of aridity-gumidity, the salt regime, lightning, moistening and soil acidity determine the floristic differentiation in the RB. A large number of scales in RB are defined by a variety of zonal vegetation types in the region which are connected with landscapes of forest, forest-steppe and steppe zones as well as a mountain-forest belt of the Southern Ural. The zonal vegetation of LR belongs only to subzones of the southern and average Taiga. The exception is the lightning scale which high values of correlation are connected with a considerable share of sunflower and corn in cultivated crops in RB.

Abstract:

This paper takes Shanghai Chongming Dongping Forest Park as the studying area; and takes the water environment in park which has the most intensive tourism activities as the research objects; selects the grey relational recognition model to analyze the temporal variation of the water environment before and after the Dongping Forest Festival, and uses PCA ordination with the ecological software CANOCO to analyze the spatial variation of water quality, so as to evaluate the impact of human tourism activities on water environment in temporal and spatial scale. The results show that: (1) the impact of agglomeration effect during the tourism festival on water environment is very obvious; the large number of tourists greatly affects the water environment near the Farmhouse Restaurant during the festival, causing substantial change of all kinds of indexes of water quality, and short-term rapid deterioration of water quality; (2) It seems from the analysis on monitoring results that after a large number of tourism activities, the self-purification capacity of water has improved, the ecological recreation activities (such as artificial ship) can effectively reduce the impact of tourism activities on the environment; it should be advocated energetically in the development and management of tourism resources; (3) From the spatial variation analysis of water quality, main pollutants of each water area can be determined through PCA ordination, the waters show three groups of feature type distribution: Group 1 (Farmhouse Restaurant, Background2, Fishing area) shows that the content of COD and the pollutants of organic increased; Group 2 (Background1) shows that the content of TN and the pollutants of organic increased; Group 3 (Barbecue area, Cruise area, Around waterway, Viewing area ) shows that the content of TN increased but the TP decreased.

Abstract:

Abstract The aim of this study is to differentiate old-field plant communities along the abandonment time and/or environmental gradient in the landscape surrounded villages with established Czech settlers in Romanian Banat area conserving traditional agriculture, and to identify site factors which cause plant diversity of particular vegetation types. Study area: Wider territory centered by the village Sfânta Elena, southern Romania ((44°40’ N; 21°43’ E). Methods: We collected 97 phytosociological relevés covered the same number of old-fields in the area and the following habitat parameters were measured: soil pH, available phosphorus, total carbon and nitrogen, Heat Load Index. Software TURBOVEG / JUICE was used to collect and elaborate the data set of relevés. Old-field vegetation was classified into five basic plant communities using TWINSPAN (all the botanical material includes 291 plant species). For each community, we detected diagnostic species according to their fidelity index. The presence of mowing, grazing or burning was registered for recorded stands. Ecological preferences of each community were examined using one-way analysis of variance (ANOVA). Vegetation-environment relationships were analysed using ordination method – Cannonical correspondence analysis (CCA) in CANOCO for Windows (version 4.5) to find the main variability gradients within the dataset. Scatter plot relationships between variables were constructed. Main results and conclusions: Dependence of number of species (alpha diversity) on the abandoned field’s age exhibits an unimodal shape of this relationship with the maximum peak of species diversity in plant stands aged approximately 13 years. The most importnat ecological factors and/or type of management in the relationship to the old-field plant composition show the following significance order: available phosphorus content in the soil (P), total nitrogen content in the soil (N), presence of burning, length of abandonment (old-field age), carbon/nitrogen ratio in the soil (C/N). Other parameters (grazing, mowing, zero management) do not demonstrate effective impact according to our dataset and seem to be equal to the absence of burning.

Abstract. The aim of this study was to describe the relationships among lambs' birth weight, survivability traits, growth performance, and selected factors in Suffolk lambs kept under a specified extensive management system. Data were collected regarding 1012 Suffolk lambs born during a 3-year period (2012–2014) in one flock. Statistical analyses were conducted using the SAS and CANOCO program software. Birth weight was found to be an important factor influencing survivability and growth performance traits. Lambs with too low a birth weight (< 2.9 kg) had the worst results of practically all the survivability and growth performance traits. A significantly lower percentage of live-born lambs (5.2 to 6.1 %; P < 0.05) was also observed amongst overweight lambs at birth (> 6.0 kg) compared to lambs with a birth weight of 4–5.9 kg. Generally, the highest results of growth performance traits were detected in groups of lambs with a birth weight of 5.0–5.9 and 6.0–9.0 kg. Therefore, the optimal birth weight of Suffolk lambs was in the range of 5.0 to 5.9 kg in the evaluated flock management system. Litter size was found to be the dominant factor influencing birth weight, survivability, and growth performance traits, such that singles tended to have the highest birth weight and growth performance traits, while higher survivability traits were found in twins. The results of multivariate relations also clearly indicated that the selection of lambs should be focused on twins with regard to the monitoring of mature ewes' live weight at mating, which helped to improve the lambs' survivability traits, in particular. The monitoring of ewes' mature live weight at mating should also serve as a tool for flock management to shorten the lambing period in the flock and to improve the birth weight and growth performance traits of lambs. The mature ewe body condition score at mating should be monitored to ensure that lambs are adequately meaty and fatty. This study confirmed the importance of keeping records of birth weight and suggested practical implications of some important factors when improving flock profitability.

Abstract:

During 2011–2012, the research of diurnal butterfly communities in ten study sites under different management measures in the vicinity of the village of Vlkolínec was performed. The village of Vlkolínec is located in the northern part of Central Slovakia in the buffer zone of the Veľká Fatra National Park. Abandoned meadows and fallows are prevailing in the study area, thus, traditional management is gradually disappearing, which results in ecosystems changing and decline of biodiversity. Adults were recorded by the modified transect method (Erhardt, 1985) in the following types of habitats: extensive and intensive pasture, old fallow lands of various successional stages and fallow lands exploited by mulching. Shannon-Weaver index of diversity (H) and equitability (e) were used for estimation of the quantitative and qualitative structure of the butterfly assemblages. To study the impact of anthropogenic factor (mulching, pasture and abandonment) on the butterfly diversity multivariable statistical methods (CANOCO 4.5 software) were used. Summarily, 2314 individuals of 63 species were sampled. The most of species were classified into the Nymphalidae family. During two-year research the highest values for number of species and diversity indices were recorded in the grasslands of late successional stages and extensive pastures. The highest number of grassland indicators and protected species, such as Limenitis populi, Melitaea aurelia, M. diamina, Polyommatus bellargus, P. daphnis, P. thersites, Thymelicus acteon and two European important species Phengaris arion and P. rebeli, were recorded in those habitats. Intensification of landscape leads to sterile grasslands, which are the unsuitable habitats for butterflies, and the main reason of negative effect of intensive grazing is a change of vegetation structure, which is the factor most of stenotopic butterflies are negatively correlated with. Extensive management has a positive impact on the assemblages of daily butterflies and landscape biodiversity, as the RDA analysis has shown for some of the localities studied where we found positive correlation of many specialized and indicator species (such as Pyrgus malvae, Polyommatus dorylas, P. thersites, P. bellargus, Melitaea aurelia). The RDA analysis has also indicated positive impact of succession on the butterfly diversity. Our results prove that intensive management, such as long-term mulching and intensive pasture, has negative impact on the abundance and structure of butterfly assemblages. Extensive pastures and old fallow lands represent important habitats of the country, however, their importance is often overlooked.

Full text

Abstract:

Establishment of an excess number of nodules markedly affects plant growth and development due to overconsumption of photosynthates for nitrogen fixation. Hence, the total root nodule number must be tightly controlled via a negative feedback mechanism (AON) to maintain an optimal nitrogen and carbon balance in chickpea plants. Chickpea genes whichplay important regulatory roles in root nodulation in chickpea (Cicer arietinum) were identified by aligning these genes with known genes of legumes available at phytozome through BLAST search. Chickpea nodulation genes identified and characterized in this study include CaNFR1/5, CaENOD40, CaNARK, CaRIC1, CaRIC2, CaNIC1, CaRDN1, CaRDN2, CaRDN3, CamiRNA172 and CaNNC1. These genes were orthologous to Medicago truncatula nodulation genes and were significantly expressed by inoculating chickpea plants with Mesorhizobium ciceri analysed by qRT-PCR using RNA isolated from the root and leaf tissues of inoculated chickpea plants at 0, 2, and 6 days after inoculation. Non-inoculated plants served as control. CaNARK genes were expressed in roots and leaves while the rest of the nodulation genes were expressed only in the roots. The nodulation ability of chickpea may be controlled by an internal AON mechanism which involves several genes that are orthologues with other legumes.

Abstract:

Abstract Intro Malnutrition represents a frequent problem in cancer patients. However, data on the prevalence and the clinical impact of malnutrition in older patients with hematological malignancies are so far rare. Objectives Objective of this study was to investigate prospectively the nutritional status at baseline in older patients with blood cancer and to analyze the impact of malnutrition on clinical performance and outcome. Goal was to form a rational basis for interventions and practice guidelines in this continuously growing group of patients. Methods In 149 newly diagnosed patients with a hematological malignancy aged ≥ 70 years from the Department of Internal Medicine V (Haematology and Oncology), Innsbruck Medical University, different nutritional parameters including loss of appetite, recent weight loss, Mini Nutritional Assessment (MNA), body mass index, serum albumin and the inflammation marker C-reactive protein (CRP) were assessed and compared with status in multidimensional geriatric assessment and with overall survival (OS). SPSS (IBM Corporation, Armonk, NY, USA) was used for all statistical analyses. Two-year overall survival was analyzed with Kaplan-Meier methods and the log rank test. Hazard ratios were first analyzed in a univariate Cox proportional hazard regression. Parameters statistically significant in the univariate analyses were then included in the multivariate Cox regressions, additionally assessing the significance of the parameters with a bootstrapped model. Canoco 5.10 was used for principal component analyses (PCA). Results A moderate or severe decrease of appetite was reported by 23 % and 40% of patients. Moreover, a recent weight loss of 1-3 or >3kg was present in 19 and 31% and a BMI <23kg/m2 was found in 29% of patients. Based on MNA-evaluation, 44% revealed a risk of malnutrition and 14% of manifest malnutrition. Prevalence of lowered serum albumin <3.5 g/dL was detected in 14% of patients. Geriatric impairments >3 were detected in about one third of the patients (36%). PCA demonstrated clustering of impairments in performance status and in IADL as well as of low appetite, low serum albumin, fatigue and depression in the first principal component accounting for a variability of 24%. Loss of appetite, recent weight loss, impaired MNA, low serum albumin and elevated CRP were significantly associated with shortened OS. Recent weight loss >3kg and low BMI remained significant predictive parameters for OS in a Cox regression analysis (HR: 2.01 (1.19-3.38), p=0.009 and HR: 2.46 (1.53-3.96), p<0.001, respectively). Conclusion These analyses reveal malnutrition at initial diagnosis in a relevant proportion of older patients with a hematological malignancy. Importantly, impaired nutritional status is associated with shortened overall survival. The correlation between malnutrition, fatigue, impaired performance and functional capacities, and inflammation might suggest an underlying common pathway. Thus, assessment of nutritional status is essential in studies and in daily practice and forms the basis for interventions to improve nutritional status. More robust data on the clinical impact of malnutrition in hematological malignancies and the effect of geriatric interventions on essential oncologic and non-oncologic outcomes such as survival and quality of life are needed.
