The results of five-year studies (2015–2019) of the laboratory of zoobenthos MMBI RAS on the impact of environmental factors, climate change and pollution on the species diversity, structure and abundance of bottom fauna in the Barents Sea were considered. The abundance and diversity of bottom communities and taxocenoses were higher in the most warm Atlantic water masses. The warming of the Arctic contributes to increased diversity of the Barents Sea benthos, increased biological invasion in the northern seas, and maintenance of diversity in the polluted ecosystem of the Kola Bay. The technology of biomonitoring of climate change using littoral populations of invertebrates is proposed.
