| dc.description.abstract | The vertical and local distribution of coastal benthonic·fish populations was studied at South Bay, Doumer Island, Palmer Archipelago, in relation to the habitats found in the marine bottom substrate.• The populations were separated according to their habitat preference utilizing three different methods: a) analysis of vertical distribution, b) analysis of relative density and e) analysis of geographic microdistribution, a measure of similarity in appearance of 43 sampling stations utilized in the summer's of 1972, 1973, 1976 and 1977. The three methods gave similar results, which permitted the grouping of similar species; one group that congregates the fishes of the algal belt and the other congregates the fishes of the sponge community. When we compared our results with the literature, we concluded that the same species occupy similar habitats in very different places around Antarctica. The probable ecological isolation of 4 congeneric species is discussed according to microhabitat within the algal belt from the observations taken while scuba diving. | es_ES |
