In most other studies of water
bodies with both natural and secondary salinity (ponds,
lakes, and rivers), the recorded number of rotifer species
was markedly lower than in our study [7, 17-19]. The
decrease in species richness with increasing salinity is a
commonly observed trend in various types of saline waters
all over the world [6, 7-9, 20, 21]. However, results on
rotifer species richness and diversity in inland saline waters
vary widely. Some authors reported a remarkable decrease
