This project aims to develop a shared experimental platform, using the well-studied ecological model, Daphnia, to test emergent predictions about evolution on invasion fronts. Evolution happens rapidly on invasion fronts, accelerating the speed and potentially the damage caused by an invasion. By manipulating invasions through an experimental landscape, the project aims to answer currently infeasible questions, including whether pathogens become more virulent as they spread, and whether evolutionary trade-offs place limits on spread rate. This work would dramatically improve our understanding of biological invasions and may have implications for the management of phenomena ranging from emergent diseases to invasive pests and malignant growths.

该项目旨在开发一个共享的实验平台，使用经过充分研究的生态模型Daphnia来测试入侵前沿进化的紧急预测。进化在入侵前沿迅速发生，加速了入侵的速度和潜在的破坏。该项目旨在通过实验环境来操纵入侵，以回答目前不可行的问题，包括病原体在传播过程中是否会变得更具毒性，以及进化权衡是否会限制传播速度。这项工作将大大提高我们对生物入侵的理解，并可能对从突发疾病到入侵性害虫和恶性生长的现象的管理产生影响。
