The continued destruction of the coastal and tropical forest in South and Central America threatens the survival of natural animal populations, including the callitrichid primates (tamarins and marmosets). While the golden lion tamarins are considered an endangered species, through a highly successful breeding program at the University of Nebraska under the auspices of the National Zoological Park, these primates are being bred in captivity and a small group of six have recently been reintroduced into forests of Brazil. Their survival as a species, however, depends extensively on understanding how their reproduction is synchronized to lead to a greater likelihood of fertilization. Dr. French will investigate the complex interplay between internal physiological factors and external social and environmental factors in gold lion tamarins. Unlike Old World primates and apes, the callitrichid primates are monogamous and thus, develop a close and long-lasting association, or pair- bond, between a breeding male and female. Dr. French will use noninvasive data collection techniques for both hormone samples and behavioral measurements to compare the degree to which social factors influence hormonal regulation of reproduction. His findings will be compared with the results obtained in similarly conducted studies in which Old World non-monogamous primate species have been used. This work will contribute to our understanding of the role of hormonal and social influences on reproductive behavior in golden lion tamarins as well as other New World primates of which many are considered threatened or endangered species. Furthermore, the results will significantly enhance the captive breeding programs of endangered species and thus, contribute to the preservation of these small South American primates.

南美洲和中美洲的沿海和热带森林的持续破坏威胁着天然动物种群的生存，包括卡利替奇·普灵伊斯（Tamarins and Marmosets）。 虽然金狮洲田植物被认为是一种濒临灭绝的物种，但通过内布拉斯加州大学的一项非常成功的育种计划，在国家动物园的主持下，这些灵长类动物被囚禁，最近又重新引入了巴西森林。 然而，它们作为一种物种的生存在很大程度上取决于了解其繁殖如何同步，从而导致更大的受精可能性。 法国博士将调查金狮菜他蛋白的内部生理因素与外部社会和环境因素之间的复杂相互作用。 与旧世界的灵长类动物和猿类不同，Callitrichid灵长类动物是一夫一妻制的，因此在繁殖的雄性和女性之间建立了紧密而持久的关联或成对的联系。 French博士将对激素样本和行为测量进行无创数据收集技术，以比较社会因素影响繁殖激素调节的程度。 他的发现将与在使用旧世界非熟练的灵长类动物的类似研究中获得的结果进行比较。 这项工作将有助于我们理解荷尔蒙和社会影响对黄金狮溪蛋白以及其他新世界灵长类动物的生殖行为的作用，其中许多人被认为受到威胁或濒危物种。 此外，结果将显着增强濒危物种的圈养育种计划，因此有助于保存这些小型南美灵长类动物。
