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 …

Bottlenecks, founder events, and genetic drift often result in decreased genetic diversity and
increased population differentiation. These events may follow abundance declines due to …

Habitat fragmentation is a fundamental cause of population decline and increased risk of
extinction for many wildlife species; animals with large home ranges and small population …

The contemporary genetic structure of animal populations is sculpted by past events,
including demographic bottlenecks and expansions and movement of animals by humans …

Although the Louisiana black bear (Ursus americanus luteolus) is currently listed as
threatened under the Endangered Species Act, there have been no attempts to estimate …

ABSTRACT The Louisiana black bear (Ursus americanus luteolus) was reduced to a few
small, fragmented, and isolated subpopulations in the Lower Mississippi Alluvial Valley by …

There is a crucial need to understand the genetic consequences of landscape modifications
on continuous populations that could become fragmented, and to evaluate the degree of …

Abstract The American black bear (Ursus americanus) experienced a significant range
contraction during the 19th and 20th centuries due to a variety of anthropogenic factors …

Abstract Historically abundant throughout Mississippi, American black bears (Ursus
