Project Description

Understanding the potentially negative impacts of chemicals on ecosystems is essential to managing them sustainably. In particular, we need to understand the effects of chemicals on the direct and indirect contributions that ecosystems make to human well-being (i.e. ecosystem services). To gain this understanding we need to move from simplistic approaches currently used in environmental risk assessment to more mechanistic and ecologically relevant understanding and approaches. A recent horizon-scanning project identified priority research questions for moving towards sustainable environmental quality, which included: How do sublethal effects alter individual fitness and propagate to the population and community levels? Biodiversity and ecosystem services: What are we trying to protect, where, when, why and how? (van den Brink et al 2018, Environ. Toxicol. Chem. 37, 2281-2295).

The ESR9 position is based in the Department of Animal and Plant Sciences at the University of Sheffield (UK) and are part of PRORISK (, a European Training Network funded by the European Union’s Horizon 2020 programme. The PRORISK consortium comprises of 18 universities, research institutions, enterprises and partner organisations in 9 European countries and Canada creating a novel platform for training a network of ESRs in the field of advanced Environmental Risk Assessment (ERA). The ESRs within PRORISK will gain synthetic skills allowing them to develop and implement innovative ERA concepts and tools to link the effects of chemicals at different levels of biological organization to ecosystem services and to determine the socio-economic values of related environmental impacts.

This PhD project will use energy-budget, population and food-web models to extrapolate chemical-induced changes in feeding rate to population and community-level responses that underpin key ecosystem function and services. The project will apply existing and novel methods to assess the effects of chemicals on ecosystem service providers and their interactions in complex assemblages. The results from this project will contribute to the development of ecological production functions to translate effects measured on ecosystem service providers to ecosystem service delivery. The project will involve international collaboration with RIVM (Netherlands) on trait-based approaches, Aarhus University (Denmark) on dynamic energy budgets and Environmental Institute (Slovakia) on field methods and exposure assessment. The project will be supervised by Professor Lorraine Maltby and Professor Philip Warren.
