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.

该奖项旨在通过在奥地利维也纳为多元化的美国本科生群体提供国际研究经验，培养全球参与的美国科学工作者。每年有五名学生将在维也纳兽医大学跨学科生命科学系的国际生态生理学研究人员的指导下，开展关于脊椎动物（包括冬眠的睡鼠和候鸟）能量平衡的个人研究项目。了解各种脊椎动物在不同环境条件下如何选择分配能源对于预测这些动物如何应对气候变化非常重要。在他们返回得克萨斯州北部，学生们将提出他们对这些主题的研究和他们的旅行经验，以当地社区的结果和更广泛的影响。比较生态生理学提供了一个独特的机会，调查的策略，其中各种脊椎动物在不同的生命阶段科普极端的能源需求下，一个潜在的气候变化。冬眠者获得了大量的身体脂肪，以维持数月的饥饿，并且寿命比他们的身体尺寸预测的要长。候鸟在大陆范围内的迁徙需要消耗大量的能量，但也必须有足够的能量来进行昂贵的繁殖行为和求偶表演。了解鸟类和哺乳动物在不同季节管理能量分配的共同策略，可以深入了解这些生物体应对气候变化可能造成的食物供应扰动的能力。IRES参与项目分为3个主要类别：1）早期生活热量限制的影响（对睡鼠的冬眠和衰老，以及对鸟类的迁徙行为）; 2）候鸟到达时间和繁殖行为的成本/收益决定; 3）鸟类求偶行为的代谢成本调节。IRES学生将参加为期一个学期的半学分出发前课程，与他们的国际研究导师合作，提供文化能力，必要的技术技能和项目设计方面的培训。在维也纳的7周时间里，学生们将开展他们的个人项目，介绍他们的研究结果，并撰写一份项目报告，在适当的情况下可以提交出版。返回美国后，学生们将在当地、地区和国家的各种场所向同行、科学界和普通观众展示他们的研究成果。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
