Postdoctoral Research Fellowship in Biosciences Related to the Environment for FY 1997

DBI 9750160弗拉基米尔·V·普拉沃多夫这一行动资助了美国国家科学基金会1997年与环境有关的生物科学博士后研究奖学金。这一奖学金为研究员提供了一个在博士学位之外获得额外科学培训的机会，并在任何生物领域的分子、细胞、组织、种群、社区和/或生态系统层面上以创新和富有想象力的方式探索生物体与其环境之间相互作用的基本机制，这一领域得到了国家科学基金会生物科学局的支持。每个研究金资助一项研究和培训计划，该计划将在一个赞助实验室进行。该奖学金的研究和培训计划名为“鸟类的社会环境和能源战略”。在温带地区，许多小鸟必须在严寒的冬天生存下来，严冬的特点是环境温度低，食物供应减少。据推测，食物储藏室鸟类使用食物储藏室作为身体脂肪储存的替代方案，使它们能够保持较低的体重。大多数储藏食物的鸟类生活在社会结构的群体中，在这些群体中，支配者优先获得食物。本研究探讨社会环境对越冬珍禽最优育肥与保育策略的影响。同时使用了经验和随机动态博弈建模方法。

Abstract DBI 9750160 Vladimir V. Pravoudov This action funds an NSF Postdoctoral Research Fellowship in Biosciences Related to the Environment for 1997. This fellowship provides an opportunity for the Fellow to gain additional scientific training beyond the doctoral degree and to pursue innovative and imaginative into the fundamental mechanisms underlying the interactions between organisms and their environment at the molecular, cellular, organismal, population, community and/or ecosystem level in any area of biology supported by the Directorate for Biological Sciences of the National Science Foundation. Each fellowship supports a research and training plan to be carried out in a sponsoring laboratory. The research and training plan for this fellowship is entitled "Social environment and energy strategies in birds." In the temperate zone, many small birds must survive harsh winters characterized by low ambient temperatures and reduced food supplies. It has been hypothesized that food-caching birds use food-caches as an alternative to body fat storage, allowing them to maintain lower body mass. Most food-caching birds live in socially structured groups where dominants have priority access to food. This research investigates the impact of the social environment on optimal fattening and caching strategies in wintering caching birds. Both empirical and stochastic dynamic game modeling approaches are being used.
