This paper presents the results of a faunistic study of the
macrozoobenthos of the Velika Morava River. The investigation was
conducted during the summer and autumn months in 2010. A total of 84
macroinvertebrate taxa have been identified, with Insecta
(Ephemeroptera) as the most diverse and Oligochaeta as the most abundant
groups. A tubificid worm, Limnodrilus hoffmeisteri, was the most
important species with regard to relative abundance and frequency of
occurrence. Two rare and endangered species, Theodoxus transversalis and
Unio crassus, were recorded, as well as 5 alien species. Locality VM4
(Markovac Bridge) is of particular interest as the northernmost
locality, as well as having the most abundant population of T.
transversalis found. Despite being in the lower stretch of the river,
this site is particularly taxa-rich, presumably due to conspicuous
microhabitat diversity. Water temperature and pH value were determined
to be the most important factors of the 32 environmental variables
tested. Multivariate analyses revealed separation of summer samples
compared to autumn. The Mann-Whitney test showed significant differences
in fauna only in the case of ecoregions, confirming their current
delineation and the transitional character of this river.
