西非锥虫病主要由河流种类的采采蝇传播。在这项研究中，我们估计分布和人口规模的采采蝇种群位于沿着Mouhoun河在布基纳法索的采采蝇栖息地正在经历越来越多的碎片化所造成的人类入侵。扩散估计通过直接（标记和重捕）和间接（遗传隔离距离）的方法出现彼此一致。在这些破碎的景观，采采蝇显示本地化，小的亚群相对较短的有效传播。我们将讨论如何这些信息是至关重要的，为消除这种威胁设计最佳策略。为了估计野生动物种群的生态参数，遗传措施是一个既经济又省时的替代标记-释放-再捕获。它们可以应用于具有医学和/或经济重要性的其他病媒传播疾病。
The West African trypanosomoses are mostly transmitted by riverine species of tsetse fly. In this study, we estimate the dispersal and population size of tsetse populations located along the Mouhoun river in Burkina Faso where tsetse habitats are experiencing increasing fragmentation caused by human encroachment. Dispersal estimated through direct (mark and recapture) and indirect (genetic isolation by distance) methods appeared consistent with one another. In these fragmented landscapes, tsetse flies displayed localized, small subpopulations with relatively short effective dispersal. We discuss how such information is crucial for designing optimal strategies for eliminating this threat. To estimate ecological parameters of wild animal populations, the genetic measures are both a cost- and time-effective alternative to mark-release-recapture. They can be applied to other vector-borne diseases of medical and/or economic importance.
