Abstract

In order to detect changes in the native communities of marine macroinvertebrates in the Bay of Cartagena, biological surveys were carried out on seven artificial substrates (buoys) of the Bay of Cartagena in different seasons during 2018 and 2019. Encrusting organisms were scraped from 30x30 cm areas, fixed and subsequently analyzed in the laboratory. A total of 9563 individuals distributed in 57 taxa were identified, among which we confirmed the presence of the bivalve Perna viridis, a species native to the Indo Pacific and reported to the region as a bioinvasive organism. 79% of the abundance of organisms consisted of 2 morphotypes of mytilidae (Mytella charruana and M1) and three species of barnacles (Amphibalanus amphitrite, Amphibalanus reticulatus and Amphibalanus eburneus). The correlation of environmental variables with the diversity and abundance of organisms through Principal Component Analysis and Standardized Empirical Orthogonal Functions allowed us to show changes in the macroinvertebrate community between the surveys carried out in addition to differences depending on depth, including a greater variation in the stations that are most influenced by the discharge of freshwater as well as those influenced by ocean waters in the areas of greatest interchange in the Bay, an aspect that probably changes with seasonal variations in the study area and the stability of the community in the water column
