The purpose of this study is to understand how natural selection on various physiological, behavioral, and life history traits in a model organism, yellow-bellied marmots, varies over time in a rapidly changing environment. By following the fate of individually-marked marmots, this research will provide new insights on the limits of evolutionary responses to environmental change. This research will transform our views of potentially "good" and "bad" changes that are driven by the environment. These methods and results should be applicable to a variety of other species that are likely to initially do "better" but may ultimately do "worse" from earlier arrival of spring conditions.The broader impacts of this project will include: (1) recruitment and training of graduate and undergraduate students from under-represented groups; (2) wide dissemination of research results to scientific audiences and the general public via scientific and popular articles and talks, and engagement with science journalists; (3) maintenance of Marmot Minutes (a blog), The Marmot Burrow (a website), and The Marmots of RMBL (a website); and (4) continuation of one of the world's longest-running studies that follows the fate of individually-marked mammals. This dataset has become an important window on the effects of climate change on a hibernating vertebrate, and a valuable data set that can be used to explore both population and evolutionary dynamics.

本研究的目的是了解在快速变化的环境中，模式生物黄腹土拨鼠的各种生理、行为和生活史特征的自然选择是如何随时间变化的。通过跟踪单独标记的土拨鼠的命运，本研究将为进化对环境变化的反应的局限性提供新的见解。这项研究将改变我们对由环境驱动的潜在“好”和“坏”变化的看法。这些方法和结果应该适用于其他各种各样的物种，这些物种最初可能做得“更好”，但最终可能因为春天的提前到来而“更糟”。该项目的更广泛影响将包括：(1)招募和培训来自代表性不足群体的研究生和本科生；(2)通过科普文章和讲座，以及与科学记者的合作，向科学受众和公众广泛传播研究成果；(3)维护《土拨鼠纪要》（博客）、《土拨鼠穴居》（网站）、《元园土拨鼠》（网站）；(4)继续进行世界上持续时间最长的研究之一，该研究追踪了个体标记的哺乳动物的命运。该数据集已成为研究气候变化对冬眠脊椎动物影响的重要窗口，并可用于探索种群和进化动态的有价值的数据集。
