9728884 Stephen H. Forbes This research focuses on cooperation among nonrelatives using theory that can be applied to both kin and nonkin based social systems. Based on detailed studies of a single species, Lasioglossum hemichalceum, several key characteristics that define cooperation in groups of nonrelatives have been identified. These include a short life span for foragers, a long period of dependency for offspring, and the need for the continued presence of adults in nests to protect orphaned offspring. These key features result in cooperation to attain "extended parental care". Individuals cooperate in order to obtain future babysitters for their offspring should they die while foraging. The investigators will examine these key characteristics in a carefully chosen set of additional species in order to determine how general the results with a single species may be. This work will be carried out using careful field observations of the factors outlined above and molecular genetic techniques to assess parentage and genetic relationships among group members. Social cooperation is an important feature of animal biology. Most terrestrial ecosystems are dominated by social species. Since the 1970s the study of social insects has provided the basis for a change in the way we view social interactions. In the past, two bodies of theory have focused on how cooperation may have evolved. The first deals with how interactions among relatives may have evolved and the second deals with cooperation among nonrelatives. This research provides the opportunity to find a more general theory of sociality with some potential for broadening our perspective on how social cooperation evolved. \\CLM-06\DEBPOP\POPBIO\ABSTRACT\FORBES.txt

9728884斯蒂芬H.福布斯 本研究的重点是非亲属之间的合作使用的理论，可以适用于亲属和非亲属为基础的社会系统。 基于一个单一的物种，Lasioglossum hemichalceum的详细研究，几个关键特征，定义合作的非亲属群体已经确定。 这些因素包括觅食者的寿命较短，后代的依赖期较长，以及需要成年人继续留在巢穴中以保护孤儿后代。 这些主要特点导致合作，以实现“扩大父母照顾”。 个体合作是为了在它们的后代在觅食时死亡时为它们寻找未来的保姆。 研究人员将在一组精心挑选的其他物种中检查这些关键特征，以确定单一物种的结果可能有多普遍。 这项工作将通过对上述因素的仔细实地观察和分子遗传技术来评估群体成员之间的亲子关系和遗传关系。 社会合作是动物生物学的一个重要特征。 大多数陆地生态系统都是由社会性物种控制的。 自20世纪70年代以来，对社会性昆虫的研究为我们看待社会互动的方式的变化提供了基础。 在过去，有两个理论体系关注合作是如何演变的。 第一个涉及亲属之间的互动如何演变，第二个涉及非亲属之间的合作。 这项研究提供了一个机会，找到一个更普遍的社会性理论与一些潜在的扩大我们的视角如何社会合作的演变。 \\CLM-06\DEBPOP\POPBIO\ABSTRACT\FORBES.txt
