With National Science Foundation support, Drs. Patricia Whitten and Trudy Turner will investigate the role of life history in divergence of populations of vervet monkeys in Kenya. This collaborative research combines data and expertise from genetics, endocrinology, morphology, demography and behavior. Life history analyses link the events and processes of an individual's life to demographic and evolutionary events at the population and species level. The timing of growth, maturation and aging have important consequences for behavior, demography and the genetic structure of populations. This research will investigate these effects using a unique data set combining genetic, morphometric and socioecological information in four ecologically distinct populations of vervet monkeys. Genetic relatedness will be assessed with 8-10 polymorphic microsatellite loci. Allele frequencies will be used to determine migration rates and differentiation among groups and populations. Paternity and maternity will be ascertained by examining allele sharing between individuals. Serum concentrations of adrenal and gonadal steroids will be assessed by radioimmunoassay. Endocrine data will be combined with morphological data to assess population differences in maturation and aging. These analyses will be used to address several questions: 1. Do males migrate to troops where they have brothers? 2. Are stress hormones higher when living in groups with more competitors and lower genetic relatedness? 3. Do stress levels in males and females and paternity in males affect behavior toward offspring? 4. Do increases in adult body size in a population result from delayed maturation and prolonged growth in males and females living in that population? 5. Do individuals in populations with richer resources mature and age more rapidly? This research is important for several reasons. The data set provides an opportunity to gain an in-depth portrait of a group of organisms that is rarely obtained in animal studies, because of both the number of animals sampled and the range of biological systems examined. These data provide a link between population level phenomena and individual physiology that will provide new insights into social behavior and life history. Within species variation in life history is poorly documented. A better understanding of the balance between facultative and evolutionary adaptations to local conditions within species can enhance our understanding of the evolution of life history differences across species.

在国家科学基金会的支持下，Patricia Whitten和Trudy Turner博士将研究生活史在肯尼亚长尾猴种群分化中的作用。这项合作研究结合了遗传学、内分泌学、形态学、人口统计学和行为学的数据和专业知识。生活史分析将个人生活的事件和过程与种群和物种水平的人口统计和进化事件联系起来。生长、成熟和衰老的时间对行为、人口统计学和种群的遗传结构有重要影响。本研究将使用一个独特的数据集，结合遗传，形态和社会生态信息，在四个不同的生态种群的长尾猴这些影响进行调查。将用8-10个多态性微卫星位点评估遗传相关性。等位基因频率将用于确定迁移率和组与人群之间的分化。通过检查个体之间的等位基因共享来确定父亲和母亲。将通过放射免疫测定法评估肾上腺和性腺类固醇的血清浓度。内分泌数据将与形态学数据相结合，以评估成熟和衰老的群体差异。这些分析将被用来解决几个问题：1。雄性会迁移到有兄弟的地方吗？2.当生活在有更多竞争对手和较低遗传相关性的群体中时，压力激素会更高吗？3.男性和女性的压力水平以及男性的亲子关系会影响对后代的行为吗？4.一个种群中成年体型的增加是否是由于生活在该种群中的雄性和雌性的成熟延迟和生长延长所致？5.资源丰富的种群中的个体是否更快地成熟和衰老？这项研究之所以重要，有几个原因。该数据集提供了一个机会，以获得一组生物体的深入画像，这是很少在动物研究中获得，因为这两个采样的动物数量和生物系统的范围检查。这些数据提供了群体水平现象和个体生理学之间的联系，这将为社会行为和生活史提供新的见解。在物种内部，生活史的变化记录得很少。更好地了解物种对当地条件的兼性和进化适应之间的平衡，可以增强我们对物种之间生活史差异的进化的理解。
