As populations become increasingly fragmented, managers are often faced with the
dilemma that intentional hybridization might save a population from inbreeding depression …

The best opportunity for endangered species recovery exists when there are still populations
throughout the original range, even if the populations are small and widely separated. As …

About 50 y ago, Crow and Kimura [An Introduction to Population Genetics Theory (1970)]
and Ohta and Kimura [Genet. Res. 22, 201–204 (1973)] laid the foundations of conservation …

Summary 1 Small and isolated populations of species are susceptible to loss of genetic
diversity, owing to random genetic drift and inbreeding. This loss of diversity may reduce the …

Genomic data are becoming increasingly affordable and easy to collect, and new tools for
their analysis are appearing rapidly. Conservation biologists are interested in using this …

Predictions about the consequences of a small population size on genetic and deleterious
variation are fundamental to population genetics. As small populations are more affected by …

Hybridization may drive rare taxa to extinction through genetic swamping, where the rare
form is replaced by hybrids, or by demographic swamping, where population growth rates …

After decades of discussion, there is little consensus on the extent to which hybrids between
endangered and nonendangered species should be protected by US law. As increasingly …

Small isolated populations may face an increasing risk of extinction due to the loss of
genetic diversity. This increasing risk, though, may be offset by gene flow, provided the …

Understanding the evolutionary role of gene flow is pivotal to the conservation of
endangered populations. Gene flow can be enhanced through population translocations …
