Although many birds are socially monogamous, most (> 75%) studied species are not strictly
genetically monogamous, especially under high breeding density. We used molecular tools …

Background Certainty of paternity is considered an important factor in the evolution of
paternal care. Several meta-analyses across birds support this idea, particularly for species …

Extra‐pair copulations (EPCs) leading to extra‐pair fertilization (EPF) are common in avian
mating systems, despite the prevalence of observed social monogamy in many species …

Vegetation structural complexity surrounding nests can either provide concealment for
intruders and mates or make it more difficult for hosts to recognize parasitic eggs. We …

The present study inferred the genetic mating system in a natural breeding population of the
Jabiru Stork (Jabiru mycteria), a Neotropical wading bird considered endangered in part of …

The term 'mating system'is used to describe how males and females obtain mates in a
population (Emlen & Oring, 1977; Thornhill & Alcock, 1982; Davies, 1991; Brown et al …

Mating with multiple males within a single reproductive event is a common female mating
strategy in mice and voles, but its adaptive function is often unclear. In this study, we used 7 …

Variation in life-history traits has long captivated ecologists and evolutionary biologists.
Classical studies of life-history theory identify latitudinal clines in life-history traits and, as a …

Abstract The Eurasian Jackdaw is thought to be archetypically monogamous, but recent
tagging research uncovered extra-pair copulations in the species. Here we examined extra …

Although nesting at high densities promotes frequent interactions with individuals other than
social mates, the rate of extra-pair paternity (EPP) in colonial waterbirds is generally low. So …
