Examined area can be found at Balaton Uplands National Park (Hungary).5 sample areas were examined in Badacsonytördemic: 1: 32 hectare under-grazed pasture, 2: 38 overgrazed 3: 34 hayfield, 4: trampled area, 5: beaten track.Livestock population was 118 the monitored pastures.Sampling executed along five 52m long circular transects, within 5cm × interlocking quadrates.Based on data we state that curve of drinking highest speciesarea examinations however weed appeared because degradation which...
Abstract This study investigates how yellow bluestem affects biodiversity in a typical Pannonian grassland. Beta diversity (i.e. the finescale spatial variability of species compositions), was estimated by realized number combinations sampled at various scales. Sampling performed standard protocol. Presences plant were recorded along 52.2 m long belt transect 1044 units 0.05x0.05 contiguous microquadrats. According to results massive presence tested C4 grass significantly reduced richness...
Abstract Aim To characterize the genetic structure and diversity of Pinus cembra L. populations native to two disjunct geographical areas, Alps Carpathians, evaluate rate differentiation among populations. Location The Swiss Carpathians. Methods We screened 28 at three paternally inherited chloroplast simple sequence repeats (cpSSRs) for length variation in their mononucleotide repeats. Statistical analysis assessed haplotypic fixation indices. Hierarchical molecular variance (AMOVA), Mantel...
After giving an overview of climate change induced vegetation shifts in the Palearctic region our previous paper, this article we review literature available Web Science on North and South America.We study different geographical regions such as Canada, Alaska, California, Southwestern, Eastern Southeastern USA, Great Lakes region, Plains, intermontane basins plateaus, Rocky Mountains Cascades well Central summarize main results relevant field studies, experiments model simulations.Predicted...
Knowledge on the expected effects of climate change aquatic ecosystems is defined by three ways.On one hand, long-term observation in field serves as a basis for possible changes; other experimental approach may bring valuable pieces information to research field.The cannot be studied empirical approach; rather mathematical models are useful tools this purpose.Within study, main findings observations and their implications future were summarized; moreover, modelling approaches discussed more...
The aim of the study is to provide a survey on history ragweed worldwide.Its climate dependence, impacts in agriculture, health effects and social costs are also presented.In Europe common (Ambrosia artemisiifolia) predominant all Ambrosia species that supported by population genetic data.The most important habitat areas highest pollen concentrations occur, decreasing order levels (1) south-western part European Russia, (2) southern eastern parts Ukraine, (3) Pannonian Plain Central Europe,...
In this paper we present the composition, seasonal dynamics and fluctuations in diversity of phytoplankton Danube River over 24 years.Weekly samplings were conducted at one section river Göd, 1669 kilometer segment.The change community structure was analyzed relation water temperature discharge means.Our findings support opinion that is very rich species, although many species are rare could be described only as coloring species.Results indicate trends abundance, which detectable long-term...
A solid body of empirical, experimental and theoretical evidence accumulated over recent years indicated that freshwater plankton experienced advance in phenology response to climate change. Despite rapidly growing for phenological changes, we still lack a comprehensive understanding how change alters freshwater. To overcome current limitations, need shed some light on trends constraints research. The goal this study is identify gaps based analysis selected papers, by the help which can...
We investigated the associations between heart rate variability (HRV) parameters and some housing- individual-related variables using canonical correspondence analysis (CCOA) method in lactating Holstein-Friesian dairy cows. collected a total of 5200 5-min interbeat interval (IBI) samples from 260 animals on five commercial farms [smaller-scale with 70 (Farm 1, n = 50) 80 cows per farm 2, 40), larger-scale 850 3, 66), 1900 4, 60) 1200 5, 45) Dependent included HRV parameters, which reflect...
The authors screened 34 large cattle herds for the presence of Mycoplasma bovis infection by examining slaughtered macroscopic lung lesions, culturing M. from lesions and at same time testing sera antibodies against bovis. Among 595 examined, 33.9% had pneumonic mycoplasmas were isolated 59.9% samples, 10.9% those animals contained to In 25.2% cases was lungs with no lesions. proportion seropositive 64.7%. average seropositivity rate individuals 11.3% but in certain it exceeded 50%.
