Blown sands are natural pecularities of Slovakia. Present data about eolic sands document the features of the primary geological substratum as well as soil types, plant and animal communities in these special natural sites. Similarly as in Slovakia these habitats are endangered in the whole Pannonian region, so they require European protection.

Roztoče (Acarina) tvoria druhovo najbohatšiu skupinou pavúkovcov (Arachnida). Na rozdiel od ostatných pavúkovcov sa veľa skupín roztočov vzdialilo od dravého spôsobu života. Niektoré skupiny sú výlučne fytofágne, zatiaľ čo iné žijú v parazitických vzťahoch so stavovcami alebo bezstavovcami. Mnohé roztoče sú považované za užitočné pre človeka, preto...

The primary factor of the origin and occurrence of xerothermic biotopes in Slovakia is the position of the landscape on the border of two biogeographical regions (mountaineous Carpathian region and floodplain Pannonian region (Eupannonicum – edges of the Eupannonian xerothermic flora). Substratum-geomorphological conditions are the second factor. T...
