Gareth Phoenix

Professor Gareth Phoenix is based at the School of Biosciences, University of Sheffield. His research focuses on plant-environment interactions in Arctic, boreal, and upland ecosystems, with particular emphasis on climate change impacts (warming, extreme events, snow regime change, precipitation), UV-B radiation, and pollution. He investigates effects on biodiversity, carbon-nitrogen-phosphorus cycling, and climate feedbacks, while extending his work to sustainable agriculture and green roof technologies.

• Academic Affiliation: Professor of Plant and Global Change Ecology
• Research Themes: Arctic browning/greening, nutrient cycling, plant stress physiology, permafrost dynamics

Research Interests span from fundamental Arctic ecosystem responses to climate change to applied urban horticulture sustainability. His team examines plant-microbe nutrient competition, extreme winter warming effects, and greenhouse gas fluxes in tundra systems. Recent work includes carbon-nitrogen-phosphorus stoichiometry and remote sensing of Arctic vegetation.

Professional roles include NERC Training Advisory Board membership, Global Change Biology editorial board, and leadership in CAPER (Committee on Air Pollution Effects Research). Teaching spans ecosystem dynamics, Arctic plant adaptations, and field-based ecological research in Abisko. Current research groups involve Murk Memon (Arctic browning), Kassandra Reuss-Schmidt (Arctic greenhouse gas emissions), and Chris Taylor (grassland carbon-nutrient interactions).
