Ecology and Evolution of Social Behavior

小行星9307502 该研究项目旨在研究高度社会化物种中竞争与合作之间的相互作用，其中群体由密切相关的个体组成。 橡子啄木鸟（Melanerpes formicivorus）生活在永久领土的家庭群体中，最多可达12只。 每一组在同一时间只有一个巢，所有的组成员帮助孵化和喂养雏鸟。 该项目的主要目标是利用现代分子技术（DNA指纹）确定不同组成群体的亲子关系。 这项工作继续研究自1971年以来完全由彩色标记鸟类组成的种群，并将联合收割机和对种群的行为观察与实验室分析相结合。 这些结果将有助于阐明为什么一些动物生活在一起，亲属关系如何促进群体生活，以及竞争在社会物种中解决的方式。 因此，所有研究社会性和行为的人，包括人类学家和社会学家以及行为生物学家，都会对这些结果感兴趣。

9307502 Koenig This research project aims to study the interplay between competition and cooperation in a highly social species in which groups consist of closely related individuals. Acorn woodpeckers (Melanerpes formicivorus) live in permanently territorial family groups of up to 12 individuals. Each group has only a single nest at a time, and all group members aid in incubation and the feeding of nestlings. The primary goal of this project is to use modern molecular techniques (DNA fingerprinting) to determine parentage within groups of different composition. The work continues study of a population consisting entirely of color-marked birds followed since 1971 and will combine banding and behavioral observation of the population with laboratory analyses. The results will help to clarify why some animals live together, how kinship facilitates group living, and the ways that competition is resolved in social species. The results will consequently be of interest to all those studying sociality and behavior, including anthropologists and sociologists as well as behavioral biologists.
