Overview of possible changes in the species composition of Dnieper-Buh estuary crustacean listed in the Red Book of Ukraine

Abstract

The Dnieper-Buh estuary is the largest water body in the Southof Ukraine, plays an important role in preserving biodiversity, richness of endemicflora and fauna and maintaining the ecological sustainability of the region. Due to itsecotone properties, it is a habitat for a large number of terrestrial, aquatic animals, hasa rich aquatic fauna (mammals, birds, amphibians, etc.). In the conditions of modernclimatic changes and active anthropogenic influence the aquatic environment of theestuaryhasundergoneanumberoftransformationswhichcanleadtoessentialhydroecologicalchanges.Insuchconditions,themostvulnerableareplanktonicorganisms that live in the water column, do not have the ability to actively moveindependently and are sensitive to even small changes in the abiotic environment.Conservation of a small number and rare species of wildlife is a particularly acuteissue when changing environmental parameters. In view of this, the current issue is toassessthestatusofrarespeciesofcrustaceansintheDnieper-Buhestuary,thesubtype of which includes mainly groups of zooplankton and benthos, and possiblechangesintheir composition.
