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.

该项目旨在通过在机械多样性模型中加入生物现实主义来管理和保护全球变化下的生物多样性。物种间的相互作用是理解地方到区域尺度生物多样性的核心。大多数多样性模型假设直接竞争捕获了物种相互作用的所有显著细节，而更复杂的物种相互作用则不重要。这种不受支持的普遍假设对如何预测和解释多样性产生了重大影响。这项研究将联合收割机将植物物种对气候和土地利用变化反应的田间实验与建模框架结合起来。预期成果包括提高管理入侵物种和在全球环境变化条件下保护生物多样性的能力。
