Species- and sex-specific connectivity effects of habitat fragmentation in a suite of woodland birds.

abstract：:Among the few universal themes in ecology is that resources, energy, and organisms themselves, are patchily distributed. This patchy distribution imposes a need for some level of dispersal or connectivity among spatially separate patches in order to allow organisms to acquire sufficient resources for survival. To date...
