Bryological and Lichenological Section/ABLS Glew, Katherine [1], Berry-Bibee, Erin [2]. Temperate - Boreal lichens and their distribution on Sakhalin Island, Russian Far East. LICHENS were collected during the summers of 2001 and 2003, as part of the International Sakhalin Island Project (ISIP). The focus of this NSF funded study was to survey the biodiversity of the island. Vegetation ranged from mixed deciduous and pine-fir forests in a warm, moist climate, to boreal larch forests with a cool oceanic influence. Two rare lichens for the island were Glossodium japonicum and Peltigera venosa. Of the more interesting locations on the island was a lagoon called Zaliv Piltun in the Okhinsky Region, at a latitude of 52°N. Conditions resembled a transition between tundra and taiga zones, occurring on the sandy coast. Over 100 collections were made at this site. Common lichens were Bryocaulon divergens, Cladonia boryi, C. phyllophora, C. rangiferina, C. uncialis, Hypogymnia sachalenensis, Ochrolechia frigida, and Vulpicida juniperinus, V. pinastri. Several brown Cetrarioides of interest: C. islandica, C. laevigata, Cetrariella delisei, C. fastigiata, and Tuckermannopsis sepincola. Comparisons were made in distributions between Sakhalin Island and similar latitudes in North America on the Pacific Coast. Several of the "tundra" lichen species occurred at lower latitudes on the island than in western coastal North America. Many species found in Europe and the Russian Far East, do not occur on the western shores of North America. Part of the explanation for the Russian distribution could be the sandy environment, common on the northern part of Sakhalin Island, and the influence of the Sea of Okhotsk, which frequently freezes in the winter.
