The rate at which an invasive species spreads, and the ability of a native species to adapt to environmental change, are both contingent on the dispersal ability of the species. Dispersal ability, however, evolves rapidly on the edge of a species' range. The rapid evolution of dispersal, therefore, determines the eventual range-limits of invasive species, as well as of native species responding to changing conditions. This research will provide tools with which to predict the direction and rate of dispersal evolution on range-edges. The results of this work will, thus, massively facilitate management of invasive species and climate change.

入侵物种扩散的速度和本地物种适应环境变化的能力都取决于物种的扩散能力。 然而，扩散能力在物种分布范围的边缘迅速进化。 因此，扩散的快速演变决定了入侵物种以及本地物种对变化条件的反应的最终范围限制。 这项研究将提供工具，预测的方向和速度的扩散演变的范围边缘。 因此，这项工作的结果将大大促进对入侵物种和气候变化的管理。
