The tropics possess exceptional numbers of species when compared to high latitudes. My research investigates the factors that drive the excess of high biodiversity in tropical regions. A key theory links high tropical biodiversity to a fast rate at which new species form, either because the tropics possess more geographic barriers that promote species diversification, or because diverging populations evolve more rapidly to become distinct species.

与高纬度地区相比，热带地区拥有数量惊人的物种。我的研究调查了导致热带地区高生物多样性过度的因素。一个关键的理论将高热带生物多样性与新物种形成的快速速度联系起来，这要么是因为热带地区拥有更多的地理障碍，促进了物种的多样化，要么是因为不同的种群更快地进化成不同的物种。
