Abstract
The objetive was to enlight the rare species contribution to biodiversity of macrobenthic community at Colorado River Estuary. The abundace data was collected by cores into intertidal zone at six points distributed on the east side of the estuary.The observed richnes and abundance data was used for estimated Chao Richness index a bias corrected, diversity by non-parametric Shannon Index, and Morisita Disimilarity Index. The biological variability was explain by CCA analysis and correlated with environmental factors (grain size, organic matter and shelter beach). The results support that the rares species beacome important for the biodiversity. The Morisita Index confirm the disimilarity of the sites. And let to indentify three biocenosis at the estuary zone.
