项目摘要

My research group uses a combination of laboratory, field, and modeling approaches to identify the ecological and evolutionary consequences of animal energetics (the process by which animals acquire and assimilate energy from the environment, and allocate assimilated energy between maintenance, growth, and reproduction). As it turns out, squirrels and chipmunks, familiar to most as visitors to backyard bird feeders and residents of urban parks, are some of the best animal models to study animal energetics, precisely because they are abundant and easy to observe, manipulate and capture. But rather than studying these species in backyards and parks, we study them where they occur in wild populations subject to natural resource-limitation and predation. We complement this small mammal research with studies on larger wildlife like moose, beaver and whales, which we conduct in collaboration with northern governments and communities. This research proposal focuses on using recent advances in biologging, which refers to the use of miniaturized animal-attached tags for logging and/or relaying of data about an animal's movements, behaviour, physiology and/or environment. We propose to deploy these biologgers on four prominent wildlife assemblages in different parts of the Canadian North to better understand how climate affects the energetic status (activity, heart rate, and body temperature) of species that interact as predators and prey or as competitors over shared respurces. This proposed research will contribute to new bioenergetic data and models that will help us document how northern environmental change will alter wildlife abundance, distribution and coexistence.

我的研究小组结合了实验室，现场和建模方法来识别动物能量学的生态和进化后果（动物从环境中获取和吸收能量的过程，并在维持，生长和生殖中分配能量）。事实证明，大多数人熟悉的松鼠和花栗鼠是后院鸟类饲养者和城市公园的居民，是研究动物能量学的一些最佳动物模型，这正是因为它们丰富且易于观察，操纵和捕捉。但是，我们没有在后院和公园中研究这些物种，而是研究它们在野生种群中发生在自然资源限制和捕食中的地方。我们通过对驼鹿，海狸和鲸鱼等较大野生动植物等大型野生动植物的研究进行补充，我们与北部政府和社区合作进行。该研究建议着重于使用生物学上的最新进展，该建议指的是使用微型动物跟踪标签来记录和/或传递有关动物运动，行为，生理和/或环境的数据。我们建议在加拿大北部的不同地区将这些生物生物部署在四个著名的野生动植物组合上呼吸。这项拟议的研究将有助于新的生物能数据和模型，以帮助我们记录北部环境变化将如何改变野生动植物的丰富性，分布和共存。
