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控制生物多样性模式的因素，并探索生物多样性对生态系统功能的重要性。几十年来，研究人员一直关注生态系统中物种的丧失，但最近，生态学家们意识到，生物多样性的丧失既是种内问题，也是种间问题。也就是说，虽然物种的消失可能对生态系统有害，但这些物种的种群数量和遗传变异的减少也会对生态系统有害。

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.
