Sotalia dolphins in their potential sympatry zone: Searching for hybrids in the Amazonian estuary
The two Sotalia species (the marine S. guianensis and the freshwater S. fluviatilis) have only recently been recognized, and both face several conservation challenges. We investigated the existence of hybridization between the two species in their possible area of sympatry in the Amazon Estuary, in...
