The sea urchin Toxopneustes roseus is widely distributed along the east coast of the tropical Pacific, from Mexico to northern Peru. In our study we evaluated population features of this species, such as population density, spatial distribution pattern and natural mortality, as well as the relationship between population density and several environmental variables. From October 2009 to September 2011 monthly sampling was carried out using belt transects in three localities of the coast of Oaxaca, Mexico: Estacahuite, Dos Hermanas and Isla Cacaluta. Additionally we recorded in situ temperature, salinity and pH in each locality. Records of irradiation and pluvial precipitation were obtained from databases. Distribution pattern of the urchins ...
