| ABSTRACT The phylum Mollusca is widely distributed in all types of environments. The species it contains are important for their multiple uses as food (as part of several trophic chains), as vectors of other groups of organisms, for the extraction of substances, and as sentinels of natural and induced environmental changes. In this work, a comparative evaluation of the malacological biodiversity associated with different habitats in the Los Petenes Biosphere Reserve in Campeche and in eight coastal water bodies in southeastern Mexico was performed. To obtain data comparable to those that were used in a previous study, data from the Los Petenes mollusks were obtained by collection of sediment cores 10 cm in diameter at a depth of 15 cm at 20 sites in... |
