Abstract
    Twenty-two stations in the intertidal and shallow sublittoral of Bjornoya (74 °N, 19 °E) were studied in August 1994 revealing a large and diverse standing crop of macro-algae (16 species) and littoral macrofauna (at least 17 species). In most places the biomass of littoral macroorganisms exceeded 100 g ww/m². In the shallow sublittoral, between 2 and 20 m, 45 animal taxa and 23 algae species were collected. Littoral coarse sand meiofauna was dominated by Turbellaria, while, on algae, Halacaridae and Harpacticoida predominated. Meiofauna densities ranged from 0 to 169 ind./10 cm² and biomass from 0 to 0.4 g dw/m². The abundance of littoral species and their zoogeographic origin resemble that of Spitsbergen more than that of the northern Scandinavian coast, although both are of equal distance from Bjornoya. The first record of the boreal bivalve Mytilus edulis from the island is presented. Another striking feature was the presence of the arctic amphipod Gammarus setosus and the absence of its boreal sibling species G. oceanicus.
