As the Earth's climate rapidly changes, species are shifting their geographic ranges towards the poles and to higher elevations. However, few species are doing so at a rate that matches rapid climate change, and many species are not shifting at all. Scientists are currently unable to predict with high confidence which species will prove capable of migration, keeping pace with climate change, nor do we know whether species that are unable to move quickly enough will be able to persist by evolving new adaptations. Accurate prediction of geographic range shifts and contemporary climatic adaptation is critical for assessing vulnerabilities of individual species, such as those that are rare, threatened, or of economic importance. It is also important for forecasting the potential spread of pests and pathogens, identifying the optimal placement of protected areas, and changes in the composition of communities and the ecosystem services they provide.Dr. Amy L. Angert is working to understand the interplay of ecology and evolution in shaping geographic ranges and responses to climate change and to extend this scientific understanding to decision-making processes about biodiversity conservation. She and her research team are investigating how interactions between species -- such as competition, predation, and herbivory -- modify responses to climatic stress at different range edges, leading to range shifts that are not well predicted by rates of climate change alone. They are also investigating how the capacity for genetic adaptation to climatic stress varies among populations across species ranges, and whether species interactions hinder or amplify capacities for rapid climatic adaptation.Dr. Angert's work will lead to refined tools for modelling and forecasting species distributions in a changing climate, providing key information for understanding the future of many animal and plant species, including many of Canada's at-risk species, which reach their northern range limits in southern Canada. Ultimately, her research will help guide management and policy decisions concerning climate change adaptation and biodiversity preservation, such as whether human-assisted migration is necessary to conserve some species.

随着地球气候的迅速变化，物种正在将其地理范围转移到极点和更高的海拔高度上。但是，很少有物种以与快速气候变化相匹配的速度这样做，而且许多物种根本没有变化。目前，科学家无法高度信心预测哪种物种将证明能够迁移，与气候变化保持同步，我们也不知道无法快速移动的物种是否能够通过发展新的适应来持续存在。对地理范围转变和当代气候适应的准确预测对于评估单个物种的脆弱性，例如罕见，威胁或经济重要性至关重要。这对于预测害虫和病原体的潜在传播，确定保护区的最佳位置以及社区组成以及他们提供的生态系统服务的变化也很重要。 Amy L. Angert正在努力了解生态学和演变的相互作用，以塑造地理范围和对气候变化的反应，并将这种科学理解扩展到有关生物多样性保护的决策过程中。她和她的研究团队正在调查物种之间的相互作用（例如竞争，捕食和草食性）如何修改对不同范围边缘气候压力的反应，从而导致范围变化，而仅由气候变化的速率很好地预测。他们还在研究跨物种范围内人群之间遗传适应性的能力如何变化，以及物种相互作用是否阻碍了快速气候适应性的能力或放大能力。 Angert的工作将在不断变化的气候下为建模和预测物种分布的精致工具，提供关键信息，以了解许多动物和植物物种的未来，包括加拿大许多高危物种，这些物种达到了加拿大南部的北部范围。最终，她的研究将有助于指导有关气候变化适应和生物多样性保护的管理和政策决策，例如为保护某些物种是否需要人为辅助移民。
