Última Abundance of the invasive lionfish Pterois volitans in the coastal coral reefs from Colombian Caribbean Boletín de Investigaciones Chasqui,Luis; Rincón-Díaz,Natalia; Vanegas,María Juliana. ABSTRACT The abundance of the invasive lionfish Pterois volitans was assessed through visual censuses conducted in 2015 and 2016 at 54 sites in six localities with coral reefs across the Colombian Caribbean coast. The invader was observed across locations and in most of the dives, with sighting frequency of 88 %, abundance values from 0 to 9.7 ± 2.1 ind/250 m2 (388 ind/ha), and 0.8 ± 1.3 ind/250 m2 (32 ind/ha) as total mean. The average density was similar to values reported in other works that counted lionfish in a broad spatial scale on the invaded area and the highest value approximated the maximum density estimated in Colombia and other locations around the Caribbean.

ABSTRACT This research is a contribution to the knowledge of some marine macroalgae species collected during the “Admiral Padilla” (2016-2017) and “Admiral Campos” (2018-2019) scientific expeditions, in which the Marine and Coastal Research Institute-Invemar participated with the project “Biodiversity and Oceanographic Conditions of the Gerlache Strait-Biogerlache-Antartica”. Samples were taken using a Shipek dredge; and underwater video recordings were made with a ROV (Remote Operated Vehicle). Six (6) species were identified: four (4) Rhodophyta and two (2) Ochrophyta-Phaeophyceae. Depth and zonation information where the macroalgae were found is included, and their relationship with previous records for the study area.

ABSTRACT Compared to other groups of invertebrates, sponge (Porifera) taxonomy has been poorly developed in the Eastern Tropical Pacific (ETP) in general and in the Colombian Pacific in particular. This work aims to increase knowledge of the group's biodiversity in the rocky reefs of northern Chocó. Sponge samples were collected by autonomous diving, which were then processed and identified in the laboratory by standard methods. It was confirmed the low species richness and the predominance of encrusting morphologies and cryptic habits, which have been found in other studies in the region. Twenty-four (24) morphotypes belonging to 13 orders, 17 families and 21 genera were identified. Twelve (12) morphotypes were recognized at the genus level or with a...
