A long-standing debate in microbial ecology is the extent to which free-living microorganisms exhibit cosmopolitan distributions. We use a comparison of testate amoebae communities in cold "polar" locations (Arctic, Antarctic, and Tibet) to investigate how ...
In the European Union, the Directive 92/43/EEC defines a number of species and habitats of community interest that are worthy to be preserved because in danger to disappear or because they are representative of the different European bio-geographical regio ...
Numerous industries and facilities have been using chlorinated ethenes (CEs) as non-flammable solvents since the beginning of the 20th century. These compounds are known to persist in the environment, exerting adverse effects. They have been considered for ...
Testate amoebae are an abundant and diverse polyphyletic group of shelled protozoa living in aquatic to moist habitats ranging from estuaries to lakes, rivers, wetlands, soils, litter, and moss habitats. Owing to the preservation of shells in sediments, te ...
We investigated species composition and relative abundance of Sphagnum fallax dominated peatlands in relation to measured environmental variables on the basis of 26 sites in the Wielkopolska region. Most of studied plots were characterised with soft waters ...

Depuis quelques années - une dizaine peut-être - nombre d’éléments tendent à montrer, pour qui sait les lire, que le modèle de la villa individuelle a vécu alors même si ce type d’habitat n’a pas forcément encore atteint son apogée. Aujourd’hui donc, à l’h ...
Species movement and occupancy of habitat patches are dependent on landscape permeability. Some land-use types (e.g., roads) may be barriers to animal movement. Analyses of the effect of landscape structure on patch occupancy usually use circular buffers a ...
In habitat modelling, an initial step is to define geoenvironmental variables to be included in a predictive model. According to Guisan and Zimmermann (2000), the selection of predictors can be made either arbitrarily, automatically by stepwise procedures, ...
In Chlebowo mire (Wielkopolska region), we investigated testate amoebae in relation to ten environmental parameters in the semi-natural floating vegetation of flooded peat workings. The measured parameters included: depth to water table (DWT), ground-water ...
