Biogeographic Zoning of Russia’s Far Eastern Seas and Adjacent Waters Based on Nekton Trawling Samples

详细

The article presents the results of biogeographic zoning of the epi- and mesopelagic region based on nekton areas using a new modification of the Shorygin method. It is shown that the position and boundaries of biogeographic areas are related to real relatively stable elements of the biotope (water masses, currents, frontal zones, eddies, and rings). A pronounced latitudinal pattern of the areas of natural zones is not always seen. Zoning becomes less detailed from the top layer of the epipelagic to mesopelagic region, and the zonalities of mesopelagic and epipelagic areas are not similar. We propose a new zoning approach to solve dynamic biogeography problems.
