Recurrent camouflaged invasions and dispersal of an Asian freshwater gastropod in tropical Africa.

ABSTRACT:

Background

Non-indigenous taxa currently represent a large fraction of the species and biomass of freshwater ecosystems. The accumulation of invasive taxa in combination with other stressors in these ecosystems may alter the habitats to which native taxa are adapted, which could elicit evolutionary changes in native populations and their ecological interactions. Assessing ecological and evolutionary consequences of invasions simultaneously may therefore be the most effective approach to study taxa with complex invasion histories. Here we apply such an integrated approach to the cerithioid gastropod Melanoides tuberculata, a model system in invasion biology.

Results

Molecular phylogenetics and ancestral range reconstructions allowed us to identify several independent Asian in
