Summary: | Abstract Stomachs of 171 vertebrates (two species offish, eight of birds and twoof seals) from Hornsund, Svalbard, were collected between 7 September and 5 October 1984. Arctic cod Boreogadus saida and the amphipod Pamthemisto libellula were the main prey species of black guillemots Cepphus grylle , little auks Alle alle , puffins Fratercula arctica , Brunnich's guillemots Uria lomvia , kittiwakes Rissa tridactyla and ringed seals Phoca hispida . Fulmars Fulmarus glacialis preyed mainly on the squid Gonatusfabricii and the polychaete Nereis irrorata . Eiders Somateria mollissima preyed mainly on bivalves and on the amphipod Gammarellus homari. G. homari and Gammarus oceanicus were the most important prey species of striped snailfish Liparis liparis , while shorthorn sculpin Myoxocephalus scorpius mainly preyed upon G. homari and Anonyx sarsi . Glaucous gulls LOTUS hyperboreus took many different prey including birds and tundra plants. Only one bearded seal Erignathus barbatus stomach with content was available for this study. |
