Whether inbreeding affects the demography and persistence of natural populations has
been questioned. However, new pedigree data from field populations and molecular and …

A series of important new theoretical, experimental and observational studies demonstrate
that just a few immigrants can have positive immediate impacts on the evolutionary trajectory …

Ten years ago, we reported that SM, a patient with rare bilateral amygdala damage, showed
an intriguing impairment in her ability to recognize fear from facial expressions. Since then …

The identification of population bottlenecks is critical in conservation because populations
that have experienced significant reductions in abundance are subject to a variety of genetic …

Genetic stochasticity due to small population size contributes to population extinction,
especially when population fragmentation disrupts gene flow. Estimates of effective …

Linking genetic diversity to extinction is a common goal in genomic studies. Recently, a
debate has arisen regarding the importance of genetic variation in conservation as some …

Although differences in sampling intensity can bias comparisons of allelic richness (A)
among populations, investigators often fail to correct estimates of A for differences in sample …

Evolutionary principles are now routinely incorporated into medicine and agriculture.
Examples include the design of treatments that slow the evolution of resistance by weeds …

Spotted hyenas (Crocuta crocuta) are large mammalian carnivores, but their societies,
called 'clans', resemble those of such cercopithecine primates as baboons and macaques …

Species diversity and genetic diversity may be correlated as a result of processes acting in
parallel at the two levels. However, no theories predict the conditions under which different …
