John L. HooglandThe evolution of polyandry in the white-tailed prairie dog, cynomys leucurus.IOS-0717097Polyandry, or multiple mating by females, is common in animals but the function of this behavior is poorly understood. Because mating involves costs such as increased exposure to diseases and parasites, the evolution and maintenance of polyandry are puzzling. Polyandry within six colonies of white-tailed prairie dogs at the Arapaho National Wildlife Refuge in Colorado will be studied. The specific goal over the next year will be to develop and optimize biochemical techniques for the assignment of paternity for those females that mate with more than one male. Accurate assignment of paternity is pivotal for investigating several hypotheses about how polyandry might evolve. Many undergraduate students are involved in this research. The project provides information about prairie dogs to new media and to the public. The research results will be useful to the State and Federal agencies that set policies concerning the preservation of this species.

John L. Hoogland白尾草原犬鼠 (cynomys leucurus) 一妻多夫的进化。IOS-0717097一妻多夫或雌性多次交配在动物中很常见，但人们对这种行为的功能知之甚少。 由于交配涉及增加接触疾病和寄生虫等成本，一妻多夫的进化和维持令人费解。 科罗拉多州阿拉帕霍国家野生动物保护区六个白尾土拨鼠群体的一妻多夫现象将被研究。 明年的具体目标将是开发和优化生化技术，为那些与多个雄性交配的雌性确定亲子关系。 准确的亲子鉴定对于调查有关一妻多夫制如何演变的几种假设至关重要。 许多本科生参与了这项研究。 该项目向新媒体和公众提供有关草原土拨鼠的信息。 研究结果将对制定有关该物种保护政策的州和联邦机构有用。
