Biodiversity of benthic macroinvertebrates on hard substrates in the Currais Marine Protected Area, in southern Brazil
Abstract This study describes the biodiversity of benthic invertebrates on hard substrates in the Currais Marine Protected Area (Currais MPA), in the state of Paraná. The benthic community was sampled during 2012 to 2015, in winter and summer, at two islands and four groups of artificial reefs (ARs)...

Zusammenfassung: | Abstract This study describes the biodiversity of benthic invertebrates on hard substrates in the Currais Marine Protected Area (Currais MPA), in the state of Paraná. The benthic community was sampled during 2012 to 2015, in winter and summer, at two islands and four groups of artificial reefs (ARs). Samples were collected along shallow (2-4 m) and deep (6-8 m) transects at the islands and ~18 m transects at the ARs. We also searched the literature to review all published records of benthic invertebrates on hard substrates in the Currais MPA. We recorded 176 taxa in the phyla Annelida (class Polychaeta), Arthropoda (class Maxillopoda, order Sessilia), Bryozoa, Cnidaria, Chordata (class Ascidiacea), Echinodermata, Mollusca and Porifera, in 13 classes, 40 orders and 75 families. With these 102 new records, our list comprises 58% of all recorded species. Of these, 58 taxa were first records for the state of Paraná. This remarkable number of new records highlights that biodiversity studies are lacking in Paraná. Fifteen non-indigenous species and one endangered species, the sea star Coscinasterias tenuispina (Lamarck, 1816), are included. This is an important transitional area to monitor expansion or constriction of the latitudinal distributions of species, in the context of climate change, that may influence the geographical distribution of species (both native and invasive). This study is the first inventory of marine hard substrate habitats of the Currais MPA with a surprisingly diverse community.
Resumo Este estudo descreve a biodiversidade da comunidade de invertebrados bênticos de ambientes rochosos da Área Marinha Protegida de Currais (AMP Currais), localizada no estado do Paraná. A comunidade bêntica foi amostrada entre 2012 e 2015, durante períodos de inverno e verão, em duas ilhas e quatro grupos de recifes artificiais (RAs). As amostras foram obtidas em transecções rasas (2-4 m) e mais profundas (6-8 m) nas ilhas e a ~18 m nos RAs. Também foi realizada uma pesquisa bibliográfica para examinar todos os registros de invertebrados bênticos publicados para a área da AMP Currais. Foram encontrados 176 táxons pertencentes aos filos Annelida (classe Polychaeta), Arthropoda (classe Maxillopoda, ordem Sessilia), Bryozoa, Cnidaria, Chordata (classe Ascidiacea), Echinodermata, Mollusca e Porifera, distribuídos em 13 classes, 40 ordens e 75 famílias. Há 102 novos registros para a área, representando 58% de todas as espécies registradas. Destes, 58 táxons não ha |
