Title

Moluscos bentónicos recolectados en la Antártida occidental durante las expediciones “Caldas”, “Almirante Padilla” y “Almirante Campos” en los veranos australes de 2014-2015, 2016-2017 y 2018-2019 = Benthic molluscs collected in Western Antarctica during the “Caldas”, “Admiral Padilla” and “Admiral Campos” expeditions, southern summers 2014-2015, 2016-2017 and 2018-2019

Abstract

This research is part of the results of the three first expeditions of Colombia to West Antarctica and it focused on the systematics and taxonomic diversity of the benthic community of molluscs collected between 5 and 400 m deep. The Sampling sites where mollusks were collected were located along the Gerlache and Bransfield straits, around the Palmer Archipelago and the South Shetland Islands, adjacent to the Antarctic Peninsula. The list of identified species that are deposited in the Museum of Marine Natural History of Colombia - Makuriwa, of the Institute of Marine and Coastal Research “José Benito Vives de Andréis” -Invemar, is presented. This inventory consisted of 15 specimens distributed in 10 taxa, of which 7 were shelled gastropods (including 5 microgastropods) and 3 were bivalves. Four microgastropods were placed in greater taxonomic categories due to the low knowledge of these taxa in the region (Anatoma sp., Cingulopsoidea sp., Truncatelloidea sp. and Eatoniella sp.). The other gastropod species (3) were Margarella antarctica, Prosipho turritusand Nacella concinna. The bivalves found were Philobrya sublaevis, Adacnarca nitens and Thracia meridionalis. The identified species have previously been recorded in West Antarctica. Some of them, like the bivalves, show a circumantarctic distribution. Nacella concinna was the most abundant taxon. In coherence with the general objective of the “BioGerlache-Antarctica” project, the results generate contributions to the biological inventories of Antarctica, contributing to expand the information to define possible conservation areas in the future.
