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

In most social mammals, some females disperse from their natal group while others remain
and breed there throughout their lives but, in a few, females typically disperse after …

Metrics derived from pedigrees are key to investigating several major issues in evolutionary
biology, including the quantitative genetic architecture of traits, inbreeding depression, and …

Animal ecologists commonly assume that the reduced fitness that often afflicts inbred
offspring will inevitably cause selection for inbreeding avoidance. Although early empirical …

Publisher Summary This chapter presents a review of mate choice and genetic quality,
defines mate choice, and discusses some of the key issues about how individuals can …

Population bottlenecks are often invoked to explain low levels of genetic variation in natural
populations, yet few studies have documented the direct genetic consequences of known …

Inbreeding avoidance is predicted to induce sex biases in dispersal. But which sex should
disperse? In polygynous species, females pay higher costs to inbreeding and thus might be …

The long-term study of animal populations facilitates detailed analysis of processes
otherwise difficult to measure, and whose significance may appear only when a large …

Despite the extensive literature describing the impacts of habitat fragmentation on the
distribution and abundance of species, fragmentation effects on life-history strategies have …

The causes and magnitude of inbreeding depression are of considerable importance for a
wide range of issues in evolutionary and conservation biology, but we have only a limited …
