Ecotype evolution in Glossina palpalis subspecies, major vectors of sleeping sickness.
BACKGROUND:The role of environmental factors in driving adaptive trajectories of living organisms is still being debated. This is even more important to understand when dealing with important neglected diseases and their vectors. METHODOLOGY/PRINCIPAL FINDINGS:In this paper, we analysed genetic dive...
