Ecological Change and Environmental Stressors

由于气候变化，地球的生态系统正在发生变化，北极的变化比其他地方更大。因此，北极的环境变化可以告诉科学家将发生在更南方的变化。然而，气候变化对北极动物健康的影响仍然知之甚少，难以预测。一个关键的未知因素是生态变化如何改变野生动物暴露于其他关键的人为环境压力源，以及这些变化如何共同影响个人和种群的健康。该项目将利用先进的化学示踪剂研究北极海洋物种作为全球环境变化的指标来解决这些问题。

Earth's ecosystems are changing due to climate change and more so in the Arctic than elsewhere. Therefore, Arctic environmental change can tell scientists about changes that will happen further south. Yet, climate change impacts on Arctic animal health remains poorly understood and difficult to predict. One critical unknown is how ecological changes may alter wildlife exposures to other key human-induced environmental stressors and how these changes may together impact the health of individuals and populations. This project will address these questions using advanced chemical tracers to study Arctic marine species as indicators of global environmental change.
