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.

这项研究的目的是了解模型生物体中各种生理，行为和生活历史特征的自然选择如何在快速变化的环境中随时间而变化。 通过遵循单独标记的摩托车的命运，这项研究将为对环境变化的进化响应局限性提供新的见解。这项研究将改变我们对环境驱动的潜在“好”和“坏”变化的看法。这些方法和结果应适用于最初可能做得更好但最终从春季状况的到来最终会“更糟”的其他各种物种。该项目的更广泛的影响包括：（1）来自代表性不足的群体的研究生和本科生的招聘和培训； （2）通过科学和流行的文章和谈判以及与科学记者的参与，将研究结果广泛传播给科学受众和公众； （3）维护Marmot分钟（博客），Marmot Burrow（网站）和RMBL（网站）的Marmots； （4）延续了世界上最长的研究之一，这是遵循单独标记的哺乳动物的命运。该数据集已成为气候变化对冬眠脊椎动物的影响的重要窗口，以及可用于探索种群和进化动态的有价值的数据集。
