Do artificial vs natural substrates cause a difference in assemblages of peracarids? A case study in the Western Mediterranean basin

The aim of this investigation was to assess the differences in terms of α-diversity, species composition and trophic structure between peracarid assemblages inhabiting artificial hard substrates and those present on natural ones at two sites in the Western Mediterranean Sea. In each one, samples wer...

In each one, samples were collected from natural and artificial substrates, and the extracted peracarids were identified to the species level. Each sample was characterised by its Total Abundance, Species Richness, and 1-D Simpson, Shannon, Margalef and Equitability indices. A cluster plot based on the Bray-Curtis coefficient was conducted to detect the presence of distinct assemblages. In addition, the proportion of individuals belonging to each feeding guild was studied. The ecological indices revealed that assemblages from the artificial substrates at the Villaricos site showed lower values of diversity, while they were more diverse at the Calpe site. These results indicated that artificial hard substrates were not always inadequate ground for these animals. The species composition differed between artificial and natural hard substrates in the two studied sites and the trophic structure was also modified, although, in this case, the changes were similar in both sites. However, the difference in both respects seems to be higher between sites than between substrates, evidencing the importance of local scale processesThe author would like to express his gratitude to Macarena Blanco for her valuable help during sampling, providing peracarid material from Calpe. Special thanks are due to Juan Moreira, professor from the Biology Department of the Universidad Autónoma de Madrid, for his valuable help in the statistical treatment of the data and its interpretation. The useful comments and suggestions of an anonymous reviewer greatly improved the quality of this work and are gratefully acknowledged, as well as professional language editing by Bridgit Mathers, from PRS LtdHellenic Centre for Marine ResearchDepartamento de BiologíaFacultad de Ciencias20232023-07-05research articlehttp://purl.org/coar/resource_type/c_2df8fbb1VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10486/710596https://dx.doi.org/10.12681/mms.31267reponame:Biblos-e Archivo.
