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

DBI 9750218安妮·M·布罗尼科夫斯基这一行动资助了美国国家科学基金会1997年与环境相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“爬行动物宿主中自然细菌种群对温度适应的进化”。肠道细菌沙门氏菌的重复热生态位进化正在爬行动物宿主滑行龟身上进行测试，这种宿主表现出不同季节和空间尺度的体温变化。沙门氏菌是热病多面手还是专家还有待确定。这些研究将集中在热专化的机制以及环境温度如何影响宿主内的细菌适合性。

Abstract DBI 9750218 Anne M. Bronikowski 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 "Evolution of temperature adaptation by natural bacterial populations in a reptile host." Repeated thermal niche evolution in the gut bacteria Salmonella is being tested within a reptile host, the slider turtle, that exhibits variable body temperatures across seasons and spatial scales. It is to be determined if Salmonella are thermal generalists or specialists. The studies will focus on the mechanisms of thermal specialization and how ambient temperatures affect bacterial fitness within the host.
