Summary
The nutritional regulation of food chain length in terrestrial arthropod communities. Little is known about how the behaviour of individual animals affects the structure and function of ecological communities. By quantifying the diet requirements of predators and comparing them to the nutrients in prey at different trophic levels, this project will test if nutrient-based foraging by predators regulates food chain length in arthropod communities.
Regime change: when and how do ecological subordinates turn dominant? This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. ....Regime change: when and how do ecological subordinates turn dominant? This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. Whilst these changes often involve degradation from productive states, we have a poor understanding of the mechanisms which drive change. Key stressors in marine systems, OA and warming are predicted to drive loss of kelp forests but we still don't understand the reality of these predictions.Read moreRead less
