The effect of nutrient level on plant structure and production in a wet grassland: a field study
(Jihočeská univerzita, 2011)Since the 1950s, agricultural intensification has affected the structure and functioning of ecological systems including wet grasslands. Our study site, a wet grassland near Třeboň, Czech Republic, was historically a sedge ... -
Spermatological characters of bothriocephalideans (Cestoda) inferred from an ultrastructural study on Oncodiscus sauridae and Senga sp.
(Jihočeská univerzita, 2011)Spermiogenesis and ultrastructure of the spermatozoon of two bothriocephalidean cestodes, Oncodiscus sauridae and Senga sp., have been studied using transmission electron microscopy. The presence of a classical pattern for ... -

Biological dinitrogen fixation by selected soil Cyanobacteria as affected by strain origin, morphotype, and light conditions.
(Jihočeská univerzita, 2011)Schopnost heterocytózních půdních sinic izolovaných z různých geografických oblastí fixovat vzdušný dusík (respektive jejich nitrogenázová aktivita ? NA) byla určována s využitím metody ARA (redukcí acetylénu). Byla ... -
Experimental examination of EFL and MATX eukaryotic horizontal gene transfers: co-existence of mutually exclusive transcripts predates functional rescue
(Jihočeská univerzita, 2011)Many eukaryotic genes do not follow simple vertical inheritance. Elongation factor 1? (EF-1?) and methionine adenosyl transferase (MAT) are enzymes with complicated evolutionary histories and, interestingly, the two cases ... -

Effect of pH on the denitrifying enzyme activity in pasture soils in relation to the intrinsic differences in denitrifier communities
(Jihočeská univerzita, 2011)The effects of pH on denitrifying enzyme activity (DEA) and on the ratio of the denitrification products, N2O and N2, were determined in three pasture soils differing in cattle impact. The linkage between intrinsic differences ... -
New view on the age-specificity of pig Cryptosporidium by species-specific primers for distinguishing Cryptosporidium suis and Cryptosporidium pig genotype II
(Jihočeská univerzita, 2011)U prasat se běžně vykytují dva druhy kryptosporidií: Cryptosporidium suis and Cryptosporidium pig genotype II. K identifikaci jednotlivých druhů a genotypů se v současné době využívají metody molekulární biologie jako je ... -
Šestý nosorožec: taxonomické zhodnocení kriticky ohroženého severního tuponosého nosorožce
(Jihočeská univerzita, 2011)Předkládaná rigorózní práce se zabývá revizí nosorožce tuponosého. Na základě detailní morfologické a genetické revize se domníváme, že oba stávající poddruhy Ceratotherium simum simum a C. s. cottoni jsou výrazně odlišní ... -
Demography of a large and common butterfly: Argynnis aglaja (Lepidoptera, Nymphalidae) studied by mark-recapture
(Jihočeská univerzita, 2011)Populační struktura, demografické parametry, mobilita a chování perlrťovce velkého (Argynnis aglaja) byly studovány na tradičně obhospodařovaných, polopřirozených podhorských loukách, za účelem objasnění relativní úspěšnosti ... -

Relation of Pleurocapsa cuprea Hansgirg to the genus Hildenbrandia (Rhodophyta)
(Jihočeská univerzita, 2011)Pleurocapsa cuprea has been originally described as a relatively common freshwater cyanobacteial species with specific habitat preferences. Due to the striking resemblance of some diagnostic features to the red algal genus ... -
Food selection in Microtus arvalis: the role of plant functional traits
(Jihočeská univerzita, 2011)Foraging by captive common voles (Microtus arvalis) was evaluated by measuring the biomass of plant species consumed in a vivaria experiment and by re-analysing of already published data on plant selection. The experiment ... -

Hemelipoglycoprotein from the ornate sheep tick, Dermacentor marginatus: structural and functional characterization
(Jihočeská univerzita, 2011)The main aim of this study is the biochemical characterization of a carrier protein from the ornate sheep tick Dermacentor marginatus, hemelipoglycoprotein, with emphasis on its size in native conditions, its glycosylation ... -
Elevational gradients in phylogenetic structure of ant communities reveal the interplay of biotic and abiotic constraints on diversity
(Jihočeská univerzita, 2011)Incorporating information on species? phylogeny into the framework of conventional community ecology, we illustrate that ant communities situated in lowlands are primarily structured by interspecific competition. In contrast, ... -
Alcathoe bat (Myotis alcathoe) in the Czech Republic: distributional status, roosting and feeding ecology
(Jihočeská univerzita, 2010)Between 2001 and 2008, we recorded Myotis alcathoe at nine sites within three distant areas in the Czech Republic. The species identification was confirmed with cyt b sequences and four distinct haplotypes were identified. ... -
