International Postdoctoral Fellows: Foraging Decisions of Mammalian Herbivores: Optimal Bite Size and Patch Dynamics

小行星9405166 该奖项是根据国际初级研究员和博士后研究员计划，该计划使美国科学家和工程师能够在国外的卓越研究中心进行三到十二个月的研究。 该计划的奖项提供了联合研究的机会，以及使用国外独特或互补的设施，专业知识和实验条件。 该奖项将支持丽莎博士十个月的博士后研究访问。Shipley与瑞典农业科学大学的Per Lundberg博士合作。 他们的研究旨在研究基于摄入率和营养质量之间的权衡来预测不同大小动物的最佳咬合大小的问题。 他们将通过基于动物大小的最佳咬合大小建模，纤维和植物次生化学与咬合大小或细枝直径之间的关系，动物的消化生理学以及咬合大小与干物质摄入率之间的关系来实现这一点。 预测将进行比较，四个自由放养的浏览草食动物物种的北方生态系统的北方瑞典饲养在冬季休眠浏览的实地和实验室观察。 ***

9405166 Shipley This award is under the International Junior Investigator and Postdoctoral Fellows Program, which enables U.S. scientists and engineers to conduct three to twelve months of research abroad at research centers of proven excellence. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award will support a ten month postdoctoral research visit by Dr. Lisa A. Shipley to work with Dr. Per Lundberg at the Swedish University of Agricultural Sciences in Umea, Sweden. Their research is designed to examine the question of predicting optimal bite size for animals of different sizes based on tradeoffs between intake rate and nutrient quality. They will do this by modelling the optimal bite size based on animal size, the relationship between fiber and plant secondary chemistry and bite size or twig diameter, the digestive physiology of the animal, and the relationship between bite size and dry matter intake rate. The predictions will be compared with field and lab observations of four free-ranging browsing herbivore species of the boreal ecosystem of northern Sweden feeding in winter on dormant browses. ***
