Paleolimnologická rekonštrukcia vývoja vodnej nádrže Veľká Vindšachta s využitím subfosílnych zvyškov pakomárov

Marcela Přidalová


The thesis deals with reconstruction of ecological changes of the Velká Vindšachta reservoir. The dated sequence of sediment cores span the last  200 years.  A total of 35 taxa were recorded with the most common taxa being Tanytarsus spp., Procladius spp. and P. nubeculosum-type.  The chironomid assemblages was divided into three zones:               VIND-Z1 contained extremely low number of chironomid head capsules and taxa. In VIND-Z2 the number of taxa and head capsules gradually increased. Procladius spp. and Tanytarsus spp. predominated, and taxa such as Cricotopus cylindraceus-type, Cricotopus sp., R. effusus-type, Psectrocladius barbatipes-type and Eukiefferiella sp. occurred just in this zone and disappeared in the surface sediment samples. The typical features of VIND-Z3 were high diversity and the lasting dominance of Procladius spp., Tanytarsus spp. and P. nubeculosum-type. This zone was characterized by a significant increase of new taxa such as Ablabesmyia spp., Microchironomus sp., Prodiamesa olivacea, Psectrotanypus varius and T. bavarica-type.
