Biocenotic characteristics of some Yucatan lentic water bodies based on invertebrate remains in sediments

The Yucatan Peninsula is a karstic environment with almost no permanent surface water flows. All freshwater lentic systems here are supported by underground water. We examined sediments, obtained with an Eckman dredge, from 25 different types of water bodies (sinkholes or cenotes, lagoons, and wetlands), to investigate their biocenotic characteristics. All systems showed differences in their zoocenoses, ostracods being the dominant group in most. Cladocera were scarce in the sediments, represented by only eight genera. It can be partially related to the near absence of a littoral zone in cenotes, due to vertical walls, and the lack of submersed vegetation. In spite of their importance, relatively little work has been done on ostracods from this region of the world.
