Checklist of marine benthic algae from the Russian continental coast of the Sea of Japan

The Summary list of algae of the Russian part of continental shelf of the Sea of Japan, compiled with data from the author and other researchers, includes 321 species. Among them, there are 62 Chlorophyta species, 86 Ochrophyta and 173 Rhodophyta. In the northern part of study area, 264 species were registered while in the southern area, including the Peter the Great Bay, 273 species were found. The species shared between both areas include 67 % of the checklist (216 species). Red algae Ahnfeltia fastigiata (Endlicher) Makienko and green algae Ulvella geniculata (N.L.Gardner) Nielsen, O'Kelly et Wysor are new records to the Russian mainland coast of the Sea of Japan. The checklist will be valuable for future studies on macroalgal biogeography and evaluation the influence of different natural and anthropogenic factors on biodiversity.
