This work was in fact to establish ties cenotic populations of marine birds and mammals of the Western Antarctic islands and find out their significance for the biogeocenoses Antarctic tundra. Subject of study: communications cenotic avifauna populations, mammal fauna, and soil invertebrate fauna of the Western Antarctic islands. The paper used in ecological and population research methods, methods of scatological analysis and extraction. As a result of research for the first time for Argentine Islands archipelago conducted found that the nematode fauna is represented by no fewer than 25 species 16 genera. From these, eight are new to the fauna of Antarctica as a whole. Determined that soil nematodes predominate among bacteriophages - 17 species, 4 species - mycophages and phytophagous wormes, 3 types - there are euryphagous organisms and one new species is insufficiently explored. Established for Argentine Islands four new species of Antarctic fish such as Dissostichus mawsoni, Bathydraco antarcticus, Harpagifer georgianus and Dissostichus eleginoides. For the first time for the fauna of cephalopods shellfish waters at Argentine Islands identified two new species of squid such as Histioteuthis macrohista and one species is currently in the process of determining and two Antarctic species of octopus, one of which Graneledone antarctica and Pareledone sp., which first identified in diet Ueddel seal in the archipelago. Territory for the first time defined the main archipelago migration background species of avifauna, and cleared in the past 14 years, all these migration rare for the region are species of birds such as A. patagonicus, A. forsteri, and T. antarctica. At the Argentine Islands archipelago conducted during the period of 2006-2010 years counted and examined seasonal dynamics and spatial allocation of 5 species of Antarctic seals and 2 species of cetaceans. Marking of individual animals fur seals, to install the set terms of their seasonal migration. In particular, the beginning of the winter migration in the Argentine Islands archipelago conducted dependent on weather conditions and mostly starts from late March and lasts until mid April. It was found that the Ueddel seal visibly detectable phenomenon topical conservatism. Marked topical direct relationship between seals and endoparasitic worms. Shown, as a P. papua and P. adeliae, between C. maccormicki and O. oceanicus formed direct trophic relationships of A. Investigated cenotic links between such species as L. dominicanus, Ph. atriceps and plant D. antarctica. The last two species play an important role in the resettlement D. antarctica between the islands of the archipelago and its penetration in the land, gradually release from the snow-ice cover under global warming. It was found that L. dominicanus, Ph. atriceps, and C. maccormicki actively promote the formation of new habitats, including Antarctic tundra. In particular, Ph. atriceps creates favorable conditions for coexistence fauna of more than 10 species of soil invertebrates and the separation of the two species; L. dominicanus - 10 species of soil invertebrates and the separation of the three species; C. maccormicki - 5 species of soil invertebrates. Through analysis of cenotic connection biocenosis Archipelago Sea and biocenosis land, created their integrated model that allows to develop mechanisms to maintain the correct Antarctic biota, in terms of sustainable development in the region of Argentina Islands.
