Análisis de la diversidad y nuevos registros de equinodermos (Echinodermata) para el Parque Nacional Revillagigedo, México

A comprehensive analysis of echinoderm diversity in the UNESCO-listed Revillagigedo Archipelago, Mexico, reveals 94 species, including five new records: two starfish (Heliaster kubiniji and Astrometis sertulifera) and three brittle stars (Ophiolepis variegata, Ophiopsila californica, and Ophiothela mirabilis). The study, conducted across four volcanic islands, found Ophiuroidea to be the most species-rich class with 31 species, followed by Asteroidea, Echinoidea, and Holothuroidea, each with 21 species. Clarión and Socorro Islands exhibited the highest species richness (60 and 58 species, respectively), while San Benedicto and Roca Partida may have underreported diversity due to limited sampling efforts. The research employed ecological analyses, including species richness, similarity, and taxonomic distinctiveness, to assess biodiversity patterns in this pristine tropical ecosystem.
