Biogenic calcite structures in Green Lake, James Ross Island, Antarctica
Elster, Josef; Nedbalová, Linda; Komárek, Jiří; Vodrážka, R.
2009 - English
Mikrobiální kalcifikované krusty byly zjištěna v antarktických jezerech na ostrově James Ross s neobvyklým složením mikrobiálních společenstev (především sinic a řas). Je to první záznam cyanobakteriálních thrombolitů v Antarktidě. Microbial carbonates (calcification) have been reported in Antarctic lakes in James Ross Island with unusual periphyton communities (cyanobacteria and green algae). This is the first record of cyanobacterial thrombolite community in Antarctica.

Evaluation of nutrient limitation and heavy metal inhibition in Antarctic streams by a miniaturized algal bioassay
Kvíderová, Jana; Elster, Josef
2009 - English
The algal growth potential and algal primary production rate of Antarctic streams (King George Island, South Shetlands) were measured in miniaturized algal bioassay to evaluate possible nutrient limitation and heavy metal inhibition. The bioassay proved nitrogen limitation in oligotrophic stream samples observed in the field. The heavy metal inhibition was not found.

Microclimate and water table fluctuation in the central part of the Weitfäller peatbogs
Kučerová, Andrea; Kučera, Tomáš; Hájek, Tomáš
2009 - Czech
Water table (WT) is high in the undisturbed parts of the Weitfäller bogs, however short-term decline of the WT was repeatedly measured in summer. Daily air temperature amplitude is quite high reaching 28.7 °C. Hladina podzemní vody v nenarušených, vegetačně velmi cenných partiích Rokyteckých slatí je celoročně vysoká, přesto dochází v letním období ke krátkodobým, výrazným poklesům v závislosti na povětrnostních podmínkách. Tyto poklesy jsou součástí přirozené dynamiky vodního režimu tohoto vegetačního komplexu. Během celého vegetačního období byly měřeny značné denní amplitudy teploty (max. 28.7 °C).

Sustainable approaches to small-area grassland and barren management with respect to flora and insect diversity
Vymyslický, T.; Fabšičová, Martina; Musil, Z.
2009 - English
This study is devoted to the determination of sustainable ways of increasing flora and insect diversity in meadows through the establishment of barren sites and fallows, which help many ephemeral plant species to reproduce from the soil seed bank. We tested the optimal time for the duration of a fallow and it seems to be 3-5 years. Significant differences were observed in the number of species and their cover between nutrient-poor and nutrient-rich areas.No massive occurence of invasive and expansive species was found. In the warm eastern part of the Podyjí NP we found plant species that had been missing there for many years.

Biodiversity and Forests in National Parks
Hédl, Radim; Svátek, M.
2009 - Czech
This paper analyses definitions of national park according to international (IUCN) and national (Czech) legislative. It concludes that there is considerable variability and that no universaly valid views are possible. Concerning the Czech National parks, the current tendency towards large unmanaged areas called wilderness is discussed. The conclusion is that despite of it usefulness, wilderness should be only one of the management strategies in order to maintain biodiversity, which is the principal purpose of existience a national park. Tento článek analyzuje definice národního parku podle mezinárodní (IUCN) a národní (české) legislativy. Konstatuje, že existuje značná různorodost a přijmout jednotný koncept není možné. Vzhledem k českým národním parkům, kde současná tendence je směrem k velkým bezzásahovým územím nazývaným divočina, článek uzavírá, že toto by mělo být jen jedno hledisko. Důvodem je ochrana biodiverzity, která je primárním účelem existence národního parku.
