The tradeoff between offspring size and number is ubiquitous and manifestly similar in
plants and animals despite fundamental differences between the evolutionary histories of …

Inbreeding depression, the deterioration in mean trait value in progeny of related parents, is
a fundamental quantity in genetics, evolutionary biology, animal and plant breeding, and …

The negative consequences of inbreeding have led animal biologists to assume that mate
choice is generally biased against relatives. However, inbreeding avoidance is highly …

Inbreeding depression, the loss of offspring fitness due to consanguineous mating, is
generally detrimental for individual performance and population viability. We investigated …

Inbreeding depression plays a major role in sha** mating systems: in particular,
inbreeding avoidance is often proposed as a mechanism explaining extra-pair reproduction …

In some animal species, individuals regularly breed with relatives, including siblings and
parents. Given the high fitness costs of inbreeding, evolutionary biologists have found it …

Inbreeding can result in inbreeding depression. Therefore, many species seek to avoid
inbreeding. However, theory predicts that inbreeding can be beneficial. Accordingly, some …

Background In socially monogamous species, reproduction is not always confined to paired
males and females. Extra-pair males commonly also reproduce with paired females, which …

Inbreeding depression refers to the reduction of fitness that results from matings between
relatives. Evidence for reduced fitness in inbred individuals is widespread, but the strength …

We investigate the effect of offspring and maternal inbreeding on maternal and offspring
traits associated with early offspring fitness in the burying beetle Nicrophorus vespilloides …
