Community structure and coexistence of the rotifers of an artificial crater lake

摘要: The community structure and dynamics of the rotifers an abandoned inundated limestone quarry are described. Zooplankton standing crop is low, but rich in species. Ploesoma hudsoni Filinia hofmanni rare or unknown a perimeter several hundreds kilometers around lake. This illustrates that (passive?) dispersal across large stretches land even occurs Temporal spatial distribution, together with specific diurnal vertical movements different seasons facilitate coexistence numerous species complex ecology contrasts small size initial propagules helped colonise
