项目摘要

FROM INDIVIDUALS TO POPULATIONS:FEMALE DECISIONS AND GROUP SIZE VARIATION IN BARN SWALLOWSPROJECT SUMMARYUsing information gathered experimentally on the individual habitat- and mate-selectiondecisions of barn swallows to model population-level patterns of group size variation, this studyoffers a new perspective for examining the causes and consequences of group breeding. Thesamples necessary to evaluate the relationship between a known signal of individual quality,feather coloration, and the social and genetic mate choice of females across different groupsizes were collected during a field experiment in 2002. Funds are requested to conduct geneticparentage analyses using variation in five polymorphic microsatellite loci. These data will (1)provide information about the differences between social and genetic mates selection andwhether these vary with group size; (2) are necessary to parameterize the mate selection rulesfor an agent-based model; and (3) will also add to our knowledge of the effects of density onfemale mate choice decisions, a relationship that has only once been examined experimentallyand has potentially large impacts on sexual selection. Additionally, the genotype data will beused for the independent honor's thesis of a Cornell undergraduate and the DNA samples willbe deposited in the Cornell Lab of Ornithology's Genetics Facility and made widely available toother researchers.

从个人到人口：女性决策和群体规模变化的谷仓吞噬物的总结信息在实验中收集了谷仓燕子的单个栖息地和伴侣选择性决定，以模拟群体大小差异的人口级别模式，该研究人员可以检查一个新的观点，以检查小组繁殖的原因和后果。在2002年的实地实验期间，收集了评估已知的个人质量，羽毛色素和遗传伴侣选择的已知信号与女性选择的社会和遗传伴侣选择之间所必需的示例。要求资金用于在五个多多型微磷灰石基因座中使用遗传性呈parentage分析。这些数据将（1）提供有关社会和遗传伴侣选择之间差异的信息，并且这些信息随群体规模而变化；（2）对于基于代理的模型的序列选择规则进行参数化是必要的；（3）还将增加我们对密度竞争选择决策的影响的了解，这种关系只有一次经过实验性研究，并且对性选择产生了很大的影响。此外，基因型数据将成为独立的荣誉论文的康奈尔大学本科生，而DNA样本将沉积在孔纳斯学遗传学设施的康奈尔实验室中，并向其他研究人员广泛使用。
