GELIDIACEAE (RHODOPHYTA) IN BAHIA-DE-BANDERAS, WESTERN PACIFIC, MEXICO

Abstract

We present the results of a floristic study of intertidal species of Gelidiaceae collected in ten localities in the Bahia de Banderas region. The study area is within an extensive overlapping transitional zone between the tropical and subtropical regions of the Mexican Pacific coast. Species of the genera Gelidium and Pterocladia were found, G. microdentatum and G. pusillum being the most abundant and widely distributed in the Bay. The local and Mexican Pacific distribution for each species is given. The number of species found in this study is compared with the numbers reported in the literature for the Mexican Pacific.
