Habitat selection may be the most studied feature of animal ecology; it also represents information crucial to the recovery of species declining due to habitat loss. Conclusions about habitat selection, however, are often sensitive to the scale -- the extent or resolution of our observations in space and time. Scale represents an impediment to drawing general conclusions across different study areas, populations, or species. This research will combine modelling and field studies of the habitat selection of northern mammals with two broad goals: (1) to develop and test a new "geostatistical model", a tool for revealing the scales at which animals respond to their environment and (2) to determine the habitat factors that affect imperiled caribou populations. Deleterious changes to caribou habitat are hypothesized to be caused by logging in the boreal forest (for threatened woodland caribou) and severe snow conditions in the High Arctic (for endangered Peary caribou).

栖息地的选择可能是动物生态学研究最多的特征。它还代表了由于栖息地丧失而下降的物种恢复至关重要的信息。 但是，关于栖息地选择的结论通常对规模敏感 - 我们在时空中观察到的程度或分辨率。 量表代表了在不同的研究领域，人群或物种中得出一般结论的障碍。 这项研究将结合北部哺乳动物栖息地选择的建模和现场研究，并结合两个广泛的目标：（1）开发和测试一种新的“地统计模型”，这是一种揭示动物对环境反应的量表的工具，以及（2）确定影响危害驯鹿种群的栖息地因素。 假设对驯鹿栖息地的有害变化是由在北极北极地区（危险的伍德兰北美地区）登录（用于危险的北极地区（对于濒临灭绝的珍珠驯鹿））引起的。
