Patrones de distribución de la riqueza de macroalgas del litoral de Jalisco y su relación con variables ambientales

The Jalisco coast presents a great heterogeneity of environments that provide the necessary conditions for the establishment anddevelopment of macroalgae; These environments are described in the present study, relating them to the diversity of macroalgaerecorded and collected in 19 locations on the Jalisco coast from 2000 to 2018. The results show that the very particular andheterogeneous characteristics and conditions in each of the locations were determinants for the richness and distribution of speciesto be different along the coast of Jalisco. The locality with the highest species richness was Chamela, with 105 registered species,being the rocky substrate where most of the species were found, regardless of the time of year (rainy and dry season). Through aclassification analysis, based on the presence/absence of species, and a non-metric multidimensional scaling (NMDS), threegeographical zones were recognized on the Jalisco coast: north, center and south, this being the one that registered the highestnumber of species. (193).
