Life on Earth has evolved spectacular diversity, with millions of living species. Some lineages, though, have diversified much more than others - among birds, for instance, the perching birds are far more diverse than the penguins, despite being of similar age. I seek to understand connections between contemporary ecology and the historical origins of biodiversity. I take a two-pronged approach to understanding these connections. First, I ask how ecology has controlled the origin of new species, working with the community of insect herbivores attacking two species of goldenrod. Second, I ask how biodiversity is packaged into regional faunas and local communities, using data from the reconstructed evolutionary histories of living organisms.

地球上的生命进化出了惊人的多样性，有数百万种生物。然而，有些谱系的多样性要比其他谱系多得多--例如，在鸟类中，栖息鸟的多样性要比企鹅多得多，尽管它们的年龄相似。 我试图了解当代生态学和生物多样性的历史起源之间的联系。 我采取双管齐下的方法来理解这些联系。 首先，我问生态学是如何控制新物种的起源的，与食草昆虫群落一起攻击两种一枝黄花。 第二，我问生物多样性是如何包装成区域动物群和当地社区，使用的数据，从重建的生物进化史。
