摘要：The composition and community parameters of the microcrustacean assemblages were studied at twenty one sampling sites located in different water bodies/habitats (open water, inner ponds, canal, reed belt) of the shallow turbid alkaline Lake Fertő/Neusiedler See. 53 taxa (24 Cladocera, 9 Ostracoda, 20 Copepoda) were recorded from the lake, Alona affinis (Leydig, 1860) and Eurytemora velox (Lilljeborg, 1853) were detected for the first time. Including these two species, the microcrustacean fauna of the lake increased to 112 (49 Cladocera, 27 Ostracoda, 36 Copepoda) species on the basis of 15 published faunistic studies. Variations in composition, species richness, density, and diversity of communities of the different water bodies of the lake became obvious. In the reed belt, significant differences were detected between the species composition of the healthy and degraded reed stands. The long-term changes in the microcrustacean fauna are in accordance with the high instability and spatial variability of lake habitats and with several factors which are consequences of the extreme shallowness (water level fluctuations, extensive reed belt, high turbidity, wind effects, periodic anoxic conditions).
