I'm Richard O'Rorke, an invertebrate and a food-web ecologist with an interest in understanding “multitrophic” systems. This involves looking at diverse feeding interactions: from microbes (bacteria, phage, fungi, unicellular and colonial Eukaryotes) to multicellular plants and animals. I work across a diverse range of marine, freshwater and terrestrial ecosystems and my motivation is to inform conservation, habitat management and also the simple pleasure of understanding this fundamental part of how our world works. Understanding the structure of food webs throws light on community succession (species replacing other species) and potentially informs how macro-evolutionary processes occur (the evolution of species). I use a diverse array of tools such as genomics, genetics, microscopy, behavioural studies and measuring the movement of nutrients through the food web (ecological stoichiometry).
