S, when by Bezzia nobilis in freshwater ones. Densities of marine organisms have been high only in brackish lakes in summer. In lakes permanently connected using the sea, one of the most abundant marine species was Hydrobia ulvae, whereas in periodically connected ones, Gammarus oceanicus. Benthic fauna PF-06454589 In stock abundance of benthic organisms was the highest in brackish costal lakes (x = 760 indiv. m-2 ), where the marine component of fauna had been identified. Because of the greatest instability of environmental situations, the lowest abundance (x = 300 indiv. m-2 ) was located in lakes periodically linked together with the sea (transitional). Important variations in density had been located involving brackish and transitional lakes (R = 0.060, p = 0.027) and freshwater and transitional lakes (R = 0.053, p = 0.029). Opposing salinity regimes (freshwater vs. brackish water) resulted in similar Animals 2021, 11, x FOR PEER Overview ten of 15 benthic fauna density values.Figure 4.
