Understanding how environmental change drives population dynamics of species is a long-standing goal of ecology. It is also critical for our ability to effectively conserve and manage threatened and invasive species, because environmental change can play a huge role in whether populations invade, persist or go extinct. More recently, scientists have begun to recognize that evolution on contemporary time scales can also play a role in influencing population dynamics. A current challenge in ecology is to integrate the role of evolution in population dynamics with the major environmental changes the world currently faces, including climate change and habitat fragmentation.

了解环境变化如何驱动物种的种群动态是生态学的长期目标。这对于我们有效保护和管理受威胁和入侵物种的能力也至关重要，因为环境变化在物种入侵、持续存在或灭绝方面发挥着巨大作用。最近，科学家们开始认识到，当代时间尺度上的进化也可以在影响种群动态方面发挥作用。当前生态学面临的挑战是将进化在人口动态中的作用与世界当前面临的主要环境变化（包括气候变化和栖息地破碎化）结合起来。
