Comparing the ecological consequences of genetic variation versus the environment for communities and ecosystems

我研究的长期目标是了解支配生物多样性格局的因素，并探索生物多样性对生态系统如何发挥作用的重要性。几十年来，研究人员一直专注于生态系统物种的丧失，但最近，生态学家们意识到，生物多样性的丧失既是一个物种间的问题，也是一个物种内的问题。也就是说，虽然物种的丧失可能对生态系统有害，但种群的丧失和这些物种内的遗传变异也可能是有害的。

The long-term goals of my research are to understand the factors that govern patterns of biodiversity and to explore the importance of biodiversity for how ecosystems function. For decades, researchers have focused on the loss of species from ecosystems, but, more recently, ecologists are realizing that loss of biodiversity is as much an intraspecific problem as an interspecific problem. That is, although the loss of species can be detrimental to ecosystems, so can the loss of populations and genetic variation within those species.
