MBON POLE TO POLE: ROCKY SHORE BIODIVERSITY OF GORGONA ISLAND

Study Extent

This study was done in three sites (La Máncora, Playa Verde, and La Ventana) of one location (Gorgona Island) during one time (October 2018).

Sampling

The sampling was performed using the: South American Research Group on Coastal Ecosystems (2012) Protocol (DOI: http://dx.doi.org/10.25607/OBP-5).

Quality Control

The taxonomic identification and QC of current scientific names was checked with WoRMS (http://www.marinespecies.org/).

Method steps

1. Samples were processed following the rocky shore intertidal protocol developed during the Marine Biodiversity Workshop: from the Sea to the Cloud, at Praia do Segredo, São Sebastião, Brasil. August 6-10, 2018.

Species of algae, lichens, and invertebrates (slow-mobile and sessile) present at rocky shores in Gorgona National Natural Park (Colombia) were registered.

The sampling was performed in three sites (La Camaronera, Playa Verde, and La Ventana) of Gorgona National Natural Park (Pacific coast of Colombia). These sites are located on the south-western side (windward) of the Island. The rocky shore types at the sites are platforms and boulders and blocks beaches. The origin of rocks is mainly volcanic, but some sedimentary rocks are also present. Tidal amplitud is ~4.5 m.
