Differential permeability of rivers to raccoon gene flow corresponds to rabies incidence in Ontario, Canada.

摘要: The correlation of landscape features with genetic discontinuities reveals barriers to dispersal that can contribute understanding present and future spread wildlife diseases. This knowledge then be used for targeting control efforts. impact natural on raccoon was assessed through analysis samples from two regions, Niagara (N = 666) St. Lawrence 802). These areas are transected by major rivers at the northern front a rabies epizootic. Genetic clusters were identified in each region using Bayesian clustering algorithms. In region, corresponding either side River. For spatially congruent not identified, despite presence intervening data consistent incidence where has been detected across River Ontario while no cases have is expectations before based progression New York. results regions suggest different permeabilities raccoons between York may attributed rivers. However, other factors also explored could this difference these study sites including shape resource distribution.
