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.

我的北阿尔卑斯生态研究项目决定了鸟类种群如何应对气候变化，气候变化的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持久性。在加拿大北部山区，鸟类生态学的工作很少，因为气候变暖的影响预计会最严重。北阿尔卑斯地区具有很强的生物物理梯度，是开展野生动物对多变环境反应研究的理想栖息地。在我之前的《北方研究补充》中，我成功地发起了一项新的研究，在2个野外地点培养了3名博士和13名本科生，研究气候变化对雷鸟和鸣禽种群的影响。猎捕雷鸟是为了维持生计和娱乐，也是北方食物网中中型鸟类和哺乳动物捕食者的主要猎物。我的长期目标是在当前和未来的环境条件下，更好地了解影响北极和高山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（景观结构和气候变化）如何影响育空地区3种雷鸟的种群结构和持久性。我们将利用无线电遥测技术对最脆弱的一群幼松鸡进行监测，以确定它们第一个冬天死亡率最高的时期和环境条件。我们还将使用温度数据记录仪和对有标记的鸟类的行为研究来研究两个北部地区的高山鸣禽，以确定能量和繁殖挑战如何导致种群变化。我的北阿尔卑斯鸟类研究的预期意义是提高对气候变化对脊椎动物影响的预测。2005年，我们开始与克卢恩第一民族（Burwash Landing）进行讨论，以调整我们的研究设计，帮助他们和其他北方人进行生物多样性规划，并在北方生态系统中可持续利用野生动物。在我的北方田野研究项目中，我将培养11名研究生HQP（8名博士，2名硕士，1名PDF）和150名本科生HQP。我们优先雇用北方人。
