Low heritability of social phenotypes in a nonpasserine waterbird
Abstract Most behavioral traits are known to be weakly heritable, possibly due to their extreme complexity and flexibility. Despite this general pattern, within-species variation in avian colony size choice has been reported to have a strong additive genetic component, but we are aware of no attempts to assess the heritability of avian sociality at the finer spatial scale. Here, we used an animal model and parent–offspring regression to quantify additive genetic variance in social phenotype (local nesting density) in a nonpasserine waterbird, the common tern Sterna hirundo. For this purpose, we used a novel experimental framework, where variation in the social environment was generated by providing birds with artificial patches of attractive nesting substrate that markedly varied in size. During 2011–2019, we collected data on social preferences for either low or high nesting density in over 250 individuals, either kin (mostly parent–offspring relationships) or non-kin recorded breeding multiple times across years. All heritability estimates of local nesting density were low (<0.10), irrespectively of fixed effects (sex and year) included in the models, data used in the modeling (all individuals vs. early recruits), or methodological approach (animal model vs. parent–offspring regression). We conclude that avian sociality, as measured at the local scale, may be much less heritable than colony size choice, as measured at the landscape level. Our study adds to the understanding of additive genetic variance in avian behavior, and it underlines a scale dependency in the heritability of behavioral traits.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
