Density and Diversity Differences of Contemporary and Subfossil Cladocera Assemblages: A Case Study in an Oxbow Lake

Cladocerans are biological indicators of environmental changes. Their remains provide information on past changes in lake environments. We studied the correspondence between contemporary Cladocera assemblages and their subfossil from an oxbow lake. sought to demonstrate that there were differences among various sites with different utilization based physical–chemical variables. The lake’s two sides used as fishing sites, where angling is main activity. middle site under nature protection high macrovegetation coverage. Contemporary sampled 21 sampling along Our research showed had higher species richness densities (36 taxa) than (29 taxa). found one Polyphemidae family only assemblage. Among differed composition density. highest second due appearance small-sized Bosmids. relationship variables some variables, such chlorophyll-a, oxygen demand, dissolved oxygen, copper, phosphide, organic matter content, significantly affected composition. assemblage was more diverse abundant one, indicating integrated may be sufficient better results total water body.
