Although the potential genetic risks associated with rare or endangered plants and small
populations have been discussed previously, the practical role of population genetics in …

Estimates of inbreeding depression obtained from the literature were used to evaluate the
association between inbreeding depression and the degree of self‐fertilization in natural …

Nearly 25% of the estimated 250 000 spec cular plants in the world may become exti the
next 50 yr (Raven 1987), and 22% ofvas. species in the United States are currently vation …

Many functional-ecological, morphological, and physiological-factors affect the occurrence
of selffertilization. Six modes of self-pollination are distinguished. These differ in whether …

▪ Abstract Inbreeding depression critically influences both mating system evolution and the
persistence of small populations prone to accumulate mutations. Under some …

Conservation genetics utilizes the tools and concepts of genetics and applies them to
problems in conservation biology. For example, molecular genetic techniques, such as …

Habitat fragmentation is one of the most ubiquitous and serious environmental threats
confronting the long-term survival of plant and animal species worldwide. As species …

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 …

One of the major problems faced by conservation biologists is the allocation of scarce
resources to an overwhelmingly large number of species in need of preservation efforts …

Laboratoty germination percentages were relatively low in small populations of royal catchfly
(Silene regia), a perennial prairie plant whose distribution has been severely reduced by …
