Variation in extra‐pair paternity (EPP) among individuals of the same population could result
from stochastic demography or from individual differences in mating strategies. Although the …

Across the animal kingdom, from honeybees to cranes to beavers, exploratory movements to
exploit resources, scout prospective territories, or otherwise gain valuable experiences and …

In species with resource-defense mating systems (such as most temperate-breeding
songbirds), male dispersal is often considered to be limited in both frequency and spatial …

Most studies on extra‐pair paternity (EPP) focus either on a specific male's extra‐pair gains
or his extra‐pair losses. For an individual bird however, mate choice or mate availability may …

Whether females should prefer to mate with old males is controversial. Old males may sire
offspring of low quality because of an aging germline, but their proven ability to reach an old …

In socially monogamous species, extra‐pair paternity may increase the strength of
intersexual selection by allowing males with preferred phenotypes to monopolize matings …

In migratory birds, mistimed arrival might have negative consequences for individual fitness,
causing population declines. This may happen if arrival time is not synchronized with …

Parent–offspring conflict over food allocation can be modeled using two theoretical
frameworks: passive (scramble competition) and active choice (signaling) resolution models …

Environmental factors can shape reproductive investment strategies and influence the
variance in male mating success. Environmental effects on extrapair paternity have …

The frequency of extrapair paternity within populations has been hypothesized to be related
to ecological and social factors, which in turn can determine the impact of extrapair paternity …
