We address fundamental questions about how genetics, physiology, behaviour and life history structure the interactions among organisms, the structure of their communities, the evolution of traits, and conservation.
Current work is funded by NERC (Links to UKRI Websites)
->The coherence of ecological stability among ecosystems and across ecological scales
->Towards a general theory of ecological impacts of multiple, simultaneous stressors
->The macroevolutionary consequences of trait correlations
->Experimental adaptation and speciation in rotifers
->Ecological drivers of the evolution of symbiosis
Other funding sources include BBSRC, Microsoft Research, The British Ecological Society, The Royal Society, The EU Marie Curie Programme, The Nuffield Foundation, and The University of Sheffield.
We partner with the World Parrot Trust, Chester Zoo and the Macaw Recovery Network.

Food Webs -- We work on food web biology. We connect foraging biology and species interactions to explore the dynamics of species and the stability, structure and function of ecological communities.
-- We provided the first mechanistic explanation of what determines the connectance (the number of interactions) and structure of a food web.
-- We explore how optimal foraging and other traits underpin predictions about the dynamics and stability of communities facing multiple simulataneous threats.
-- We develop models to explore the dynamics of populations, communities/biodiversity and ecosystem function.

Ecology, Evolution & Phenotypic Plasticity -- We work on predator-prey interactions and predator induced phenotypic plasticity. We use Daphnia pulex, several rotifer species and several algae species and their morphological defences as a model organism.
-- We examine the genetic, genomic and endocrine basis of predator induced phenotypic plasticity.
-- we have advanced our understanding of how to evaluate genetic and phenotypic trade-offs and detect local adaptation of traits and of plasticity in these traits.
-- we developed statistical tools to analyse the ecology and evolution of multivariate phenotypic plasticity.
-- We use our ideas to develop sustainable, ecology inspired solutions to engineering problems, including mitigation of eutrophication and production of low and high value algae based products.

Parrots and Conservation Biology-- We work on parrots, linking their demography to socioeconomic constraints and trade-offs that influence their management as endangered species.
We have long term collaborations with the World Parrot Trust centred on biological and social science research into what makes parrot conservation work. We work in Bonaire on Yellow Shouldered Amazons, in Costa Rica on McCaws and theoretically on the demography and economics of parrots.
