Abstract

The objective of this work was to study the different bentónic landscapes that they conform the marine environment of the coastal zone of Chabihau, Yucatan, Mexico. We studied the geo-morfofunctional composition of the benthos by taking and analyze of video-transects. This technique is a method that allows to analyze bentonic communities without disturbing its environment. In order to observe group tendencies we applied to the data a hierarchic method of group and the index of similarity of Gower. Three main subaquatics landscapes were observed: bed of grass, seaweed and sandy covers. With these data, we made the supervised classification of a satellite image of LANDSAT TM of the zone of study, the different landscapes were located geographically and we made an estimation of the represented area by each one of these. The zone of study has anample productive potential by the presence of numerous species of socioeconomic importance, like the shrimp, that reproduce and raise in the zone of adjacent wetlands, finally to inhabit the different marine land scapes from the region. The information generated in this study provides a wide panorama on the landscapes that conform the zone and constitutes the basic knowledge for the accomplishment of future studies focused in the planning and sustainable handling of the resources in this region.
