中文简介: | 生态过程通常涉及不同层次的组织,从单个物种个体开始,通过一个特定物种的许多个体的种群,直至一个由许多不同物种的大量种群组成的多样群落,这些种群相互之间以及与它们的物理环境相互作用。将诸如物种特征和生物量资源反馈等低级别属性向上扩展到诸如植被模式和物种多样性等社区级别属性,是理论家的一个极具挑战性的目标。在这篇演讲中,我将描述我们小组在旱地植物群落中为实现这一目标所取得的最新进展。 |
课程简介: | Ecological processes generally involve different levels of organization, starting with a single species individual, through a population of many individuals of a given species, and up to a diverse community consisting of large populations of many different species interacting among themselves and with their physical environment. Upscaling low-level attributes, such as species traits and biomass-resource feedbacks, to community level properties, such as vegetation patterns and species diversity, is a highly challenging goal for theorists. In this talk I will describe recent progress our group has made towards achieving this goal in the context of dryland plant communities. |
