 en Distribution and habitat preferences of the genus Biomphalaria check for this species in other resources (Gastropoda: Planorbidae) in Cuba

Abstract

A study was carried out to determine the distribution and habitat preferences of several species of the genus Biomphalaria check for this species in other resources . Samples were taken at 350 freshwater locations in Cuba. Three species of Biomphalaria ( Biomphalaria havanensis check for this species in other resources , Biomphalaria helophila check for this species in other resources and Biomphalaria pallida check for this species in other resources ) were recorded based on their distribution. Of the three species, B. havanensis has the weakest distribution because it was identified in only one locality. The other species, B. helophila and B. pallida, are abundant in rivers and dams and have large populations in Cuba. However, the only species that appears to occur in ecosystems shared with thiarids is B. pallida, possibly due to recent introduction of thiarids, but always in fewer numbers. Here we discuss the possibility of these species to act as intermediary hosts of Schistosoma mansoni check for this species in other resources in Cuba over the basis of occurrence in natural and anthropic habitats.
