First genetic evidence that animals use...( the researchers found that gene flow ...)

, the researchers found that gene flow did not vary with habitat type in deer mice: populations in all three types of site pairs were equally related to each other. Likewise, this makes sense because deer mice are habitat generalists that thrive in all three types of habitat studied.

Because forest corridors increased gene flow between vole populations, Mech and Hallet conclude that corridors can help connect populations of habitat specialists. This suggests that managers should preserve corridors of forest when planning timber harvests.
