My Northern Alpine Ecology research program determines how bird populations deal with climate variability, the intensity and frequency of which is increasing with climate change. There is growing concern that components of climate change will alter animal distribution, reproduction, and ultimately wildlife persistence. Little avian ecology work has been done in mountain areas in Northern Canada where the impacts of climate warming are expected to be most severe. The Northern Alpine is an ideal habitat to initiate studies on wildlife responses to variable environments, given their strong bio-physical gradients. With my previous Northern Research Supplement, I successfully initiated new research that trained 3 PhD and 13 Undergrad HQP on the impacts of climate change on ptarmigan and songbird populations at 2 field locations. Ptarmigan are hunted for subsistence and recreation, and are also key prey species for mid-sized avian and mammalian predators in Northern food webs. My long-term objective is to better understand the key drivers influencing wildlife populations for Arctic and Alpine ecosystems, in current and future environmental conditions. We will study how two key ecological processes (landscape structure, climate variation) influence population structure and persistence for 3 ptarmigan species in the Yukon. We will use radio telemetry on juvenile grouse, the most vulnerable cohort, to determine the periods and environmental conditions of highest mortality in their first winter. We will also study alpine songbirds in two northern locations using temperature data loggers and behavioural studies on marked birds to determine how the energetic and reproductive challenges result in population change. The expected significance of my Northern Alpine Avian Research is to improve predictions for impacts of climate change on vertebrates. In 2005, we began discussions with the Kluane First Nation (Burwash Landing) to adapt our study designs to assist them and other Northerners in biodiversity planning and sustainable wildlife use in Northern Ecosystems. In my Northern field research program, I will train 11 graduate HQP (8 PhD, 2 MSc, 1 PDF) and >15 undergraduate HQP. We give priority to hiring Northerners.

我的北方阿尔卑斯山生态学研究计划确定鸟类种群如何应对气候变化，其强度和频率随着气候变化而增加。人们越来越担心气候变化的组成部分将改变动物的分布，繁殖，并最终改变野生动物的生存。在加拿大北方山区，人们对鸟类生态学的研究很少，因为那里的气候变暖的影响预计最为严重。北方阿尔卑斯山是一个理想的栖息地，开始研究野生动物对可变环境的反应，因为它们具有很强的生物物理梯度。与我以前的北方研究补充，我成功地启动了新的研究，培训3博士和13个本科生HQP气候变化对松鸡和鸣禽种群的影响在2个领域的位置。雷鸟被猎杀的生存和娱乐，也是关键猎物的中型鸟类和哺乳动物的捕食者在北方食物网。我的长期目标是更好地了解在当前和未来的环境条件下影响北极和阿尔卑斯生态系统野生动物种群的关键驱动因素。我们将研究两个关键的生态过程（景观结构，气候变化）如何影响人口结构和持久性的3种松鸡在育空地区。我们将使用无线电遥测的幼年松鸡，最脆弱的群体，以确定期间和环境条件的最高死亡率在他们的第一个冬天。 我们还将研究高山鸣禽在两个北方的位置使用温度数据记录仪和标记鸟类的行为研究，以确定如何在人口变化的精力和生殖的挑战。我的北方阿尔卑斯山鸟类研究的预期意义是改善对气候变化对脊椎动物影响的预测。在2005年，我们开始与克卢恩第一民族（伯沃什登陆）讨论，以适应我们的研究设计，以帮助他们和其他北方人在生物多样性规划和可持续利用野生动物在北方生态系统。在我的北方实地研究计划中，我将培养11名研究生HQP（8名博士，2名硕士，1名PDF）和>15名本科生HQP。我们优先雇用北方人。
