Familiarity, Kin Groups, and Persistence in Sub-Divided Populations

小行星9508319 我们建议研究移民的影响无关的个人的繁殖成功的既定居民的栖息地补丁。 进入陌生群体的雄性或雌性通常会通过对年轻个体进行捕杀或扰乱正常的繁殖模式来破坏繁殖。 本研究将记录繁殖成功，生存和种群增长的灰尾田鼠在栖息地补丁不同程度的隔离。 动物运动、存活和数量将通过在实验围栏内活捕、标记和释放动物来确定。 这项研究将使我们能够测试亲属关系与不熟悉的作用，在繁殖成功的动物在破碎的景观。 有人建议建造走廊，使动物能够在碎片之间移动，作为维持因人类活动而日益碎片化的可生存种群的一种机制。 这项研究将有助于我们管理栖息地斑块的能力，增加我们对繁殖成功的行为的影响的理解。

9508319 Wolff We propose to study the effects of immigration of unrelated individuals on the breeding success of established residents in a habitat patch. Males or females that enter unfamiliar groups often disrupt reproduction by committing infanticide on young individuals or by disturbing normal breeding patterns. This study will document breeding success, survival, and population growth of the gray-tailed vole in habitat patches differing in degree of isolation. Animal movement, survival, and numbers will be determined by live-trapping, marking, and releasing animals within experimental enclosures. This study will allow us to test the role of kinship versus unfamiliarity in the breeding success of animals in fragmented landscapes. Construction of corridors to permit movement of animals between fragments has been suggested as a mechanism for maintaining viable populations increasingly fragmented by human activity. This study will contribute to our ability to manage habitat patches by increasing our understanding of the effect of behavior on breeding success.
