Consequences of severe habitat fragmentation on density, genetics, and spatial capture-recapture analysis of a small bear population.

Sean M Murphy, Ben C Augustine, Wade A Ulrey, Joseph M Guthrie, Brian K Scheick, J Walter McCown, John J Cox,

Loss and fragmentation of natural habitats caused by human land uses have subdivided several formerly contiguous large carnivore populations into multiple small and often isolated subpopulations, which can reduce genetic variation and lead to precipitous population declines. Substantial habitat loss and fragmentation from urban development and agriculture expansion relegated the ... Read more >>

Demographic consequences of anthropogenic influences: Florida black bears in north-central Florida

Hostetler, Walter McCown, Garrison, Neils, Barrett, Sunquist, Simek, Oli,

Anthropogenic habitat fragmentation poses a serious threat to conservation of large carnivores, due to their extensive movements and potential conflicts with humans. We studied the population ecology of Florida black bears (Ursus americanus floridanus) for 6years in two study areas in north-central Florida: Ocala National Forest (ONF), a contiguous forested ...

Genetic consequences of habitat fragmentation and loss: the case of the Florida black bear (Ursus americanus floridanus)

Jeremy D Dixon, Madan K Oli, Michael C Wooten, Thomas H Eason, J Walter McCown, Mark W Cunningham,

Habitat loss and fragmentation can influence the genetic structure of biological populations. We studied the genetic consequences of habitat fragmentation in Florida black bear (Ursus americanus floridanus) populations. Genetic samples were collected from 339 bears, representing nine populations. Bears were genotyped for 12 microsatellite loci to estimate genetic variation and ... Read more >>

Effectiveness of a regional corridor in connecting two Florida black bear populations.

Jeremy D Dixon, Madan K Oli, Michael C Wooten, Thomas H Eason, J Walter McCown, David Paetkau,

Corridors may mitigate the adverse effects of habitat fragmentation by restoring or maintaining connectivity between disjunct populations. The efficacy of corridors for large carnivores, however has rarely been evaluated objectively. We used noninvasive sampling, microsatellite analysis, and population assignment tests to evaluate the effectiveness of a regional corridor in connecting ... Read more >>
