The idea that plant-animal interactions are more intense in the tropics underpins much thinking about tropical ecology, global patterns in plant traits, and latitudinal gradients in biodiversity. In this project, we will provide the first direct and global test of this idea by quantifying the intensity of herbivory, seed predation and density-dependent seedling mortality at approximately 100 study sites around the world. We will also investigate the causes of these latitudinal gradients by determining which environmental variables are most closely associated with the strength of biotic interactions.

植物与动物的相互作用在热带地区更为强烈，这一观点支撑了对热带生态学、植物性状的全球模式和生物多样性的纬度梯度的许多思考。在这个项目中，我们将提供第一个直接和全球性的测试，通过量化的草食动物，种子捕食和密度依赖的幼苗死亡率在世界各地约100个研究地点的强度。我们还将通过确定哪些环境变量与生物相互作用的强度最密切相关来调查这些纬度梯度的原因。
