The rate of recent climate warming is unprecedented and has already impacted biological systems at many levels. Recently, the need for information on current biodiversity status and how it will change with climate change has emerged.******My research program is to seek a stronger understanding of the conditions underlying responses to environmental change through the study of temporal and spatial variation in mammalian diversity. My research integrates a number of tools for studying the impacts of environmental changes on multi-species assemblages, considering simultaneously the effects of the physical environment, biotic interactions, as well as the evolutionary context, on these assemblages under global change. ******My research has some important practical implications for understanding the patterns of loss and gain of mammalian (inter and intraspecific) diversity under climate change. More generally, my work will help to improve our knowledge of the adaptive limits of species in rapidly changing environments. At present, such data are not available for most non-model mammal species. A better understanding of the evolutionary potential of species is a question under intense study given the current extent of biodiversity loss. In this context, my research is significant because it enlarges the scales at which the evolution of biodiversity is studied, as I generate data from the recent and historical records. I apply a range of methods to enhance the strength of inference, which lays out a conceptual and methodological framework for interpreting and predicting changes in mammalian diversity under climate change.**

最近的气候变暖速度是前所未有的，已经在许多层面上影响了生物系统。最近，出现了对有关目前生物多样性状况及其将如何随着气候变化而变化的信息的需求。我的研究项目是通过研究哺乳动物多样性的时空变化，寻求对环境变化反应的基础条件的更强理解。我的研究整合了一些工具，用于研究环境变化对多物种组合的影响，同时考虑物理环境，生物相互作用，以及进化背景下，这些组合在全球变化的影响。** 我的研究对理解气候变化下哺乳动物（种间和种内）多样性的丧失和获得模式具有重要的实际意义。更一般地说，我的工作将有助于提高我们对物种在快速变化的环境中的适应极限的认识。目前，大多数非模式哺乳动物物种的此类数据不可用。鉴于目前生物多样性丧失的程度，更好地了解物种的进化潜力是一个正在深入研究的问题。在这种情况下，我的研究是重要的，因为它扩大了生物多样性的进化研究的规模，因为我从最近和历史记录中生成数据。我应用了一系列方法来增强推理的强度，这为解释和预测气候变化下哺乳动物多样性的变化奠定了概念和方法框架。
