OVERVIEW


Research in the lab centres on species interactions in an evolutionary and ecological context. We address fundamental questions about how genetics, physiology, behaviour and life history influence the distribution, interaction among and abundance of organisms.

  • We work on predator-prey interactions and predator induced phenotypic plasticity using Daphnia pulex morphological defences as a model organism.
  • We work on algae biotechnology and ecosystem services, focusing on grazer induced defences in algae
  • We work on multiple stressor biology, examining how anthropogenic stress like metals combine with natural stress like predation to shape species traits and population growth.
  • We work on food web biology and the theory of complexity and connectance, tying species interactions to foraging biology.
  • We work on parrots, linking their demography to socioeconomic constraints and trade-offs that influence their management as endangered species.

Funding sources include NERC, BBSRC, Microsoft Research, The British Ecological Society, The Royal Society, The EU Marie Curie Programme, The Nuffield Foundation, and The University of Sheffield.

:: The genetics and physiology of predator induced phenotypic plasticity ::

We examine the genetic, genomic and endocrine basis of predator induced phenotypic plasticity.
  • Predator induced changes in morphology, life history and behaviour
  • The quantitative genetics and evolutionary ecology of phenotypic plasticity
  • The genetics and genomics of phenotypic plasticity

:: Algae Biotechnology and Ecosystem Function ::

With Jags Pandhal in Chemical and Biological Engineering, we work to explore the ecological opportunities for solving engineering problems, including mitigation of eutrophication and production of low and high value algae based products.

:: Optimal foraging theory and food web structure ::

In collaboration with Phil Warren at Sheffield and Owen Petchey in Zurich, we explore the role that optimal foraging theory can play in predicting pattern and process in food webs.
  • What determines connectance (the number of interactions) and structure of a food web?
  • How does optimal foraging predict the dynamic consequences of species invasions and extinctions in a food web.

:: Conservation Biology of Amazon Parrots ::

In cooperation with the World Parrot Trust (CASE partner; Dr. Jamie Gilardi), PhD student Tamora James is building models of the Yellow Shouldered Amazon Parrot Amazona barbadensis demography to assess not only extinction risk and habitat issues, but develop it into a bio-economic model for conservation decision making. We are also working in Malaysia on firefly biodiversity and conservation.
