The legacy of rainfall patterns in dryland ecosystems

点击翻译按钮获取中文摘要

This project aims to use an experimental approach to determine how rainfall regime structures dryland communities and ecosystem properties and potential responses to altered rainfall regime. Ecosystem functioning in drylands is governed by complex interactions between microbes, invertebrates and plants. Biological activity however is constrained by the availability of water and altered rainfall regimes that could moderate how organisms interact, potentially causing trophic cascades and even ecosystem state changes. By linking observed responses with soil microbial functional attributes using newly developed molecular techniques the project seeks to provide a mechanistic insight into ecosystem responses to climate variability and extreme climatic events.
