Offspring sex ratios in wild bird populations, and the extent to which they vary from the
equality expected by random genotypic sex determination, have received much recent …

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

Inbreeding–environment interactions occur when inbreeding leads to differential fitness loss
in different environments. Inbred individuals are often more sensitive to environmental stress …

Conservation genetics studies of populations bottlenecks are commonly framed under the
detrimental paradigm of inbreeding depression. This conceptual paradigm presupposes a …

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 …

Inbreeding may increase the extinction risk of small populations. Yet, studies using modern
genomic tools to investigate inbreeding depression in nature have been limited to single …

The effect of environmental stress on the magnitude of inbreeding depression has a long
history of intensive study. Inbreeding–stress interactions are of great importance to the …

Reduced fitness through genetic drift and inbreeding is a major threat to small and isolated
populations. Although previous studies have generally used genetically verified pedigrees …

Background Understanding the fitness consequences of inbreeding is of major importance
for evolutionary and conservation biology. However, there are few studies using pedigree …

We review evidence for and against the use of erythrocyte indicators of health status and
condition, parasite infection level and physiological stress in free‐living vertebrates. The use …
