- Macroalgas en arrecifes rocosos de Bahía Fildes y Collins, Isla Rey Jorge, Antártica Mauricio Palacios César A. Cárdenas Emma M. Newcombe Ciencias de la Tierra Seaweeds Antarctica species richness Fildes and Collins Bays The aim of this work was to carry out a qualitative assessment of the subtidal algal assemblages occurring at Fildes and Collins Bays. We conducted subtidal sampling of seaweeds between 1 and 10 m in Collins and Fildes Bay during late summer 2009. Our results showed that Rhodophyta was the most diverse group (63% of species) followed by Phaeophyceae (33.3%) and Chlorophyta (3.7%). Differences in species richness and structure of algal assemblages were recorded between sites. Depth significantly influenced algal assemblages; however there was a significant interaction between site and depth, suggesting that the effect of depth varied among sites. Observed differences between sites may be explained by differences in ice-scour disturbance, habitat heterogeneity (availability of refugia) and identity of canopy-forming species. 2015 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47941332014 es http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.2 Vol.50
