Abstract
Large branchiopods (Crustacea: Anostraca, Notostraca, Spinicaudata, Laevicaudata) of the middle Dyje river area, Czech Republic. Acta Musei Moraviae, Scientiae biologicae (Brno) 98(1): 1–40. – Distribution data on large branchiopods (Anostraca, Notostraca, Spinicaudata, Laevicaudata) from the middle Dyje river area are summarised.
Recently, in the period 1997–2013, the following seven species have been recorded in this area: Branchipus schaefferi Fischer, 1834, Chirocephalus carnuntanus (Brauer, 1877), Eubranchipus grubii (Dybowski, 1860), Streptocephalus torvicornis (Waga, 1842), Triops cancriformis (Lamarck, 1801), Leptestheria dahalacensis (Rüppell, 1837), Imnadia yeyetta Hertzog, 1935 and Lynceus brachyurus O. F.
Müller, 1776. Finding of the clam shrimp Imnadia yeyetta represents the first reliable country record for the Czech Republic and so far the northernmost known occurrence spot of the species.
Findings of the fairy shrimp Chirocephalus carnuntanus represent a new records from the Czech Republic after more than 30 years and findings of the fairy shrimp Streptocephalus torvicornis represent the only known findings of adults in the wild in the Czech Republic since 1957, the species was thus rediscovered in southern Moravia after 40 years. Ecology, phenology, habitat preferences, syntopic occurrence, keeping and breeding in semicaptivity and conservation status of large branchiopods recorded in the study area are discussed.
