VAZQUEZ PERERA, Antonio Alejandro  y  GUTIERREZ AMADOR, Alfredo. Ecology of river mollusks of medical and veterinary importance in 3 sites in La Habana province. Rev Cubana Med Trop [online]. 2007, vol.59, n.2, pp. 0-0. ISSN 1561-3054.

An ecological research study was carried out in freshwater mollusk populations of medical and veterinary importance, in order to determine the biotic and abiotic factors that affect their dynamics. It was observed that the principal abiotic factors influencing abundance of mollusks were total hardness, salinity, acidity, alkalinity and CO₂ concentration. Both aquatic plants and specific relations among mollusk groups were the principal biotic factors that affected the molluskan fauna. Species like Fossaria cubensis and Tarebia granifera appeared affected when the site diversity increased whereas the tiarid Melanoides tuberculata prevailed in almost all the ecosystems.
