Extra-pair Paternity in the Common Murre1
Multi-locus DNA fingerprinting was used to estimate the frequency of extra-pair paternity in the Common Murre (Uria aalge), a colonial, sexually monomorphic seabird that breeds at very high densities and in which extra-pair copulation is frequent. Common Murres produce a single chick. We detected 6 cases of extra-pair paternity in 77 families (7.8%). This value was higher than the proportion of...
متن کاملLifespan, lifetime reproductive performance and paternity loss of within-pair and extra-pair offspring in the coal tit Periparus ater.
The hypothesis that females of socially monogamous species obtain indirect benefits (good or compatible genes) from extra-pair mating behaviour has received enormous attention but much less generally accepted support. Here we ask whether selection for adult survival and fecundity or sexual selection contribute to indirect selection of the extra-pair mating behaviour in socially monogamous coal ...
متن کاملExtra-pair paternity in Seaside Sparrows
Seaside Sparrows (Ammodramus maritimus) nest at varying population densities, and breeding pairs may occupy either large, all-purpose activity spaces or small nesting territories, foraging in undefended areas separate from the nest site. We determined the prevalence of extra-pair paternity in a large, socially monogamous population of Seaside Sparrows nesting in small, overlapping territories. ...
متن کاملExtra-pair paternity in the long-tailed finch Poephila acuticauda
Although the majority of passerine birds are socially monogamous, true genetic monogamy is rare, with extra-pair paternity (EPP) occurring in almost 90% of surveyed socially monogamous species. We present the first molecular data on the genetic breeding system of the long-tailed finch, Poephila acuticauda, a grass finch endemic to the tropical northern savannah of Australia. Although the specie...
متن کاملExtra-Pair Paternity in Birds: Review of the Genetic Benefits
Question: How well are genetic benefits hypotheses for extra-pair paternity supported by empirical evidence? Data incorporated: Almost all published studies testing for genetic benefits from 1980 onwards (121 papers, 55 species). Analysis methods: Collected key features and findings of each study in a database. Determined overall level of support for both good genes and compatible genes hypothe...
