Macroalgas en arrecifes rocosos de Bahía Fildes y Collins, Isla Rey Jorge, Antártica

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 dive...
