Marine benthic algae of the South Kamchatka state wildlife sanctuary (Kamchatka, Russia)

Abstract

Abstract We present new data on marine algae of the South Kamchatka state wildlife sanctuary (Yuzhno-Kamchatskii Zakaznik, Russia), a protected natural area of federal significance. The species list of macrophytic marine algae is accompanied by information on their reproduction and distribution. This list updates the taxonomy and expands a previous list, with many new species, including 2 species previously unknown from the Pacific coasts of Russia (Colaconema endophyticum, Acrochaetium plumosum), 2 species new to the coasts of Kamchatka (Colaconema daviesii and Acrochaete geniculata), and 11 species recorded for the first time from the area studied (Erythrocladia irregularis, Palmaria hecatensis, Palmaria mollis, Meiodiscus concrescens, Crossocarpus lamuticus, Cirrulicarpus ruprechtianum, Rhodomela sibirica, Urospora elongata, Zygomitus reticulatus, Acrochaete ramosa, Acrochaete pterosiphoniae) (Nagai) Zhigadlova, comb. nov. (=Entocladia pterosiphoniae). The importance of the wildlife sanctuary for the conservation of biodiversity in Kamchatka is noted.
