The present paper presents significant changes occurred in the multi-annual dynamics of zooplankton diversity and abundance (1980-2007), under the pressure of human-induced eutrophication in two shallow lakes specific for the Danube Delta. Zooplankton community from lakes Matita and Merhei was characterized by high species richness but low abundance values until 1981, in ecological conditions unaffected by eutrophication. For the next ten years,

The dynamics of forest arthropod communities can be completely understood only when based on their trophic connections. Given their importance in detritic food chains with their influence on the rate of decomposing organic matter and the dynamics of nutrients, terrestrial arthropods from litter and soil are useful in monitoring changes in environmental conditions in forest ecosystems. Due to their flexible diet they cannot be appropriately assigned
