Long-term datasets quantifying survival and movements of known individuals can lead to exceptional insight into the ecology of natural animal populations while providing information critical for conservation and management. When combined with knowledge of genetic relatedness of individuals, and phenotypic measurements of behavioural or physiological traits, this can enable study of mechanisms of natural selection and evolutionary change within populations. These datasets exist for a few species of rodents and ungulates but are lacking for the vast majority of mammals. I propose to use passive integrated transponders (PIT tags) to individually mark large numbers of little brown bats (Myotis lucifugus) and big brown bats (Eptesicus fuscus) from hibernacula in Manitoba and Northwestern Ontario, while also collecting phenotypic measurements and tissue samples for molecular analysis. Pilot work from our study sites has confirmed that PIT tags and a custom-designed antenna system can provide excellent long-term data in this study system because we have access to large numbers of animals that reliably pass through small openings amenable to monitoring using PIT antennas. This proposal is highly time-sensitive because of predicted impacts of White-Nose Syndrome, especially on little brown bats, within the next several years. I propose to outfit large numbers of bats with PIT tags prior to the arrival of WNS, while also obtaining genetic samples from all of these individuals, and phenotypic measurements from as large a sample as possible. This work will allow my students and I to quantify selection on molecular, behavioural and physiological traits in response to environmental variation and disease.

对已知个体的生存和活动进行量化的长期数据集可以对自然动物种群的生态产生特殊的洞察，同时提供对保护和管理至关重要的信息。当结合个体遗传关系的知识和行为或生理特征的表型测量时，这可以使研究种群内的自然选择和进化变化的机制成为可能。这些数据集存在于少数几种啮齿动物和有蹄类动物身上，但对绝大多数哺乳动物来说是缺乏的。我建议使用无源集成应答器(PIT标签)来分别标记来自马尼托巴省和安大略省西北部冬眠的大量小棕蝠(Myotis Lucifugus)和大棕蝠(Eptesicus Fuscus)，同时还收集表型测量和组织样本进行分子分析。我们研究地点的试点工作证实，坑标签和定制设计的天线系统可以在本研究系统中提供出色的长期数据，因为我们可以接触到大量动物，这些动物可靠地通过可以使用坑天线进行监测的小开口。这项建议对时间高度敏感，因为预计在未来几年内会出现白鼻症，特别是对小棕色蝙蝠的影响。我建议在WN到来之前为大量的蝙蝠配备PIT标签，同时也从所有这些个体获得基因样本，并从尽可能大的样本中进行表型测量。这项工作将使我和我的学生能够量化分子、行为和生理特征上的选择，以应对环境变化和疾病。
