The effect of microbial diversity vs function on marine holobionts

点击翻译按钮获取中文摘要

This project aims to integrate a central theme of modern ecology - the relationship between biodiversity and functioning of communities - with the new biological paradigm of holobionts, where organisms are the entirety of the host plus its associated microbiome. This project blends marine and microbial ecology, aiming to experimentally decouple effects of microbial diversity versus function on the performance of dominant marine holobionts, habitat-forming seaweeds. Expected outcomes are to characterise key microbial taxa and functions and their effects on seaweed performance, and how this is affected by environmental stress. This will provide significant benefits, such as providing critical information and new tools for understanding and managing a major Australian ecosystem.
