The relative importance of local and regional factors to community build-up is a core issue in contemporary ecology. Studies based on research of newly created aquatic habitats may improve understanding of these processes. We monitored zooplankton colonization rates and community assemblage in 20 newly dug and isolated temporary pools in Kokořínsko Protected Landscape Area. The region is characterised by deep stream valleys, extensive land use, low human influence, low waterfowl migration activity and practically absence of large water bodies. After the first hyproperiod all temporary pools were rebuilt to a permanent form. In contrast to expectations, in both cases we observed immediate colonization of newly created habitats by two main groups of zooplankton (crustaceans and rotifers), but only rotifers (Rotifera) were capable of fast successful establishment of viable populations. Cladocerans (Crustacea: Cladocera) and copepods (Crustacea: Copepoda) were observed rarely and usually in low abundances (< 1 ind-l ). 10 months after the filling of permanent pools one ostracod species (Crustacea: Ostracoda), Notodromas monacha, was recorded as well. During the 8 months of temporary pools existence the presence of 1 cladoceran and 1 cyclopoid copepod species and 12 rotifer taxa was recorded, icluding...
