Abstract
The paper presents results of nine years of research (1994-2002) dedicated to the role of aquatic invertebrates in wader distribution. The stocks of forage resources and their dynamics are assessed for the first time. Forage resources of Sivash exceeded the waders intake as follows: in Eastern Sivash during the spring migration - by 21.5-28.7 times, during the autumn migration – 6.2-10.9 times; in Central Sivash – 2.4 times in spring, and 5.7 times in autumn, correspondingly. A total of 62 species of aquatic invertebrates were recorded in the diet (Kirikova, Antonovskiy, 2010). They included 2 species of Polychaeta, 7 species of Crustacea (Anostraca - 1, Isopoda - 3, Amphipoda - 3 species), 11 species of Gastropoda and 2 species of insect larvae (Insecta) - 2 species. Among the taxonomic groups, the greatest number of species was represented by mollusks and crustaceans. Our research shows that Sivash can be referred as the most valuable wetland in Eastern Europe for migrating waders due to the consistently high indices of forage macrozoobenthos and extensive shallows suitable for bird feeding during migratory stopovers.
