Jeremy’s research focuses on understanding the factors that determine change in species’ abundance, distributions and specializations.

Much of his work involves studying the population, community, functional or evolutionary ecology of insects, and much was inspired by the need to manipulate insect populations in order to solve conservation problems. Successful applications include the re-establishment of the globally endangered Large blue butterfly in the UK.

Of particular relevance to the food system is his research on:

  1. Devising methods to acquire, interpret and analyze extensive datasets describing continental-scale patterns of change in the abundance and distributions of insect species in response to climate and other environmental changes, using data collected by thousands of skilled amateurs in the field
  2. Minimalist studies of the population dynamic interactions of various insect species with their resources and natural enemies in various anthropogenic ecosystems, including responses to geographical and temporal changes in climate
  3. Collaborations to model study systems to explore evolutionary and population dynamic changes resulting from a changing environment.      

Professor Thomas is Professor of Ecology in the Department of Zoology, a Fellow of New College and of NERC’s Centre for Ecology & Hydrology, a  visiting Professor at the University of Reading, and President of The Royal Entomological Society.
