Community structure of conspicuous echinoderms of three islands from the Gulf of California, México

María Dinorah Herrero Perezrul, Saúl Rojero León y Héctor Reyes Bonilla

The objective of this study was to analyze the community structure of conspicuous echinoderms in three islands in the southern Gulf of California: San José, Espíritu Santo and Cerralvo. A total of 140 belt transects (25 x 2m) were used to assess the echinoderm communities. We estimated species richness, abundance, diversity and evenness. 23 echinoderms species were identified (12 Asteroids, 7 Echinoids and 4 Holothurians). San José showed the highest values of richness and the most diverse was Cerralvo. Asteroids were well distributed along the islands, but Espíritu Santo had more species. Phataria unifascialis was the most abundant asteroid in the three islands. At San José, the most abundant echinoid was Toxopneustes roseus, at Espíritu Santo was Eucidaris thouarsii and at Cerralvo was Tripneustes depressus. The most abundant holothurian was Holothuria fuscoscinerea, found in San José and Espíritu Santo, but in Cerralvo was Isostichopus fuscus, an important protected species.
