This award aims to grow a globally engaged U.S. scientific workforce by providing an international research experience in Vienna, Austria to a diverse group of U.S. undergraduate students. Five students per year will conduct individual research projects on energy balance in vertebrates (including hibernating dormice and migratory birds), mentored by a dynamic group of international ecophysiology researchers at the Department of Interdisciplinary Life Sciences of the University of Veterinary Medicine in Vienna. Understanding how various vertebrate animals choose to allocate energy resources under different environmental conditions is important for predicting how those animals might respond to a changing climate. On their return to north Texas, students will present the results and broader implications of their research on these topics and their travel experience to the local community.Comparative ecophysiology provides a unique opportunity to investigate the strategies by which various vertebrates at different life stages cope with extreme energy demands under a potentially changing climate. Hibernators gain extensive body fat to fuel survival over months of aphagia, and have lifespans longer than predicted for their body size. Migratory birds expend immense amounts of energy to fuel continent-scale migrations, but also must have sufficient energy for costly breeding behaviors and courtship displays. Understanding the common strategies by which birds and mammals manage energy allocation in different seasons may provide insights into the ability of these organisms to deal with the likely perturbations of food availability due to climate change. IRES participant projects fall into 3 main categories: 1) effects of early-life caloric restriction (on hibernation and ageing in dormice, and on migratory behavior in birds); 2) cost/benefit decisions of arrival time and breeding behavior in migratory birds; 3) regulation of metabolic costs of courting behavior in birds. IRES students will participate in a semester-long half credit pre-departure course providing training in cultural competency, necessary technical skills, and project design in collaboration with their international research mentors. During their 7 weeks in Vienna, students will carry out their individual projects, present on their findings, and write up a project report that where appropriate may be submitted for publication. On their return to the US, students will present their research to peer, scientific, and general audiences in a variety of local, regional, and national venues.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项旨在通过向奥地利维也纳的国际研究经验为多元化的美国本科生提供国际研究经验，以增加全球参与的美国科学劳动力。每年有五名学生将在维也纳兽医学院跨学科生命科学系的一组动态的国际生态生物学研究人员指导下，对脊椎动物的能量平衡（包括冬眠的宿舍和候鸟）进行单个研究项目。了解各种脊椎动物如何选择在不同的环境条件下分配能源资源对于预测这些动物如何应对气候变化很重要。回到北德克萨斯州后，学生将介绍他们对这些主题的研究的结果和更广泛的含义，以及他们向当地社区的旅行经验，提供了一个独特的机会，可以调查各种生活阶段的各种脊椎动物在不同的生命阶段应对潜在变化的气候下的极端能源需求的策略。冬眠者会获得大量的体内脂肪，以助长数月的aphagia生存，并且其寿命比其体型的预期更长。迁徙鸟类花费了大量的能源来燃料大陆规模的迁移，但也必须具有足够的能量来实现昂贵的繁殖行为和求爱。了解鸟类和哺乳动物在不同季节中管理能量分配的常见策略可能会提供有关这些生物体处理可能因气候变化引起的粮食供应扰动的能力的见解。 IRES参与者项目分为3个主要类别：1）早期热量限制的影响（对宿舍的冬眠和老化以及鸟类的迁徙行为）； 2）成本/收益决定到达时间和迁徙鸟类的繁殖行为； 3）调节鸟类的代谢成本。 IRES的学生将与国际研究导师合作，参加一半学期的一半学分前学会课程，提供文化能力，必要的技术技能和项目设计培训。在维也纳的7周内，学生将在他们的发现中进行个人项目，并写出一份项目报告，即在适当的情况下可以提交出版。在返回美国后，学生将在各种地方，地区和国家场所向同伴，科学和一般受众展示他们的研究。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子评估来支持的，并具有更广泛的影响。
