How complex species interactions mediate plant community diversity

点击翻译按钮获取中文摘要

This project aims to manage and protect biodiversity under global change by adding biological realism to mechanistic diversity models. Species interactions are central to understanding biodiversity at local to regional scales. Most diversity models assume that direct competition captures all salient details of species interactions, while more complex species interactions are unimportant. This unsupported, pervasive assumption has major consequences for how diversity is predicted and explained. This study will combine field experiments on plant species’ responses to climate and land use changes with a modelling framework. Expected outcomes include improving the ability to manage invasive species and to protect biodiversity under conditions of global environmental change.
