Algas marinas bentónicas de la Isla Gorgona, costa pacífica colombiana

Abstract

Benthic marine algae of Gorgona island, Colombian Pacific coast. The knowledge of the biodiversity of Gorgona, a continental island in Colombia, is very limited in the case of algae. We present an updated list of the benthic marine algae of Gorgona island, associated with different marine environments and type of substrates, such as coral reefs, rocks, and soft bottoms. Field samplings were taken between October 2010 and June 2011. We estimated algal cover, species composition and algal diversity for each reef environment using 0.25 m 2 quadrats. Ecological and environmental aspects are also included. A total of 43 species of algae for the three types of habitats are documented: 24 Rhodophyta, 12 Clorophyta, six Ochrophyta and one species of Cyanobacteria, and 55% of the algal composition corresponded to red algae.
