One of the greatest unmet challenges in conservation biology is the
genetic management of fragmented populations of threatened animal
and plant species. More than a million small, isolated, population
fragments of threatened species are likely suffering inbreeding
depression and loss of evolutionary potential, resulting in
elevated extinction risks. Although these effects can often be
reversed by re-establishing gene flow between population fragments,
managers very rarely do this. On the contrary, genetic methods are
used mainly to document genetic differentiation among populations,
with most studies concluding that genetically differentiated
populations should be managed separately, thereby isolating them
yet further and dooming many to eventual extinction! Many small
population fragments are going extinct principally for genetic
reasons. Although the rapidly advancing field of molecular genetics
is continually providing new tools to measure the extent of
population fragmentation and its genetic consequences, adequate
guidance on how to use these data for effective conservation is
still lacking. This accessible, authoritative text is aimed at
senior undergraduate and graduate students interested in
conservation biology, conservation genetics, and wildlife
management. It will also be of particular relevance to conservation
practitioners and natural resource managers, as well as a broader
academic audience of conservation biologists and evolutionary
ecologists.
