Multistress effects on fish pathogen interactions – MULTIPAT

Submission summary

Global changes expose wild populations to increasing pollution and emerging pathogens, which could have complex interactive effects on organism health. However, the ways in which multiple stressors and intraspecific variability scale up to shape health and disease risk remain poorly understood. Based on an “Ecohealth” perspective at the crossroad between ecotoxicology, health ecology and evolutionary ecology, this project will explore the impacts of contamination on host-pathogen interactions across generations, from molecules to populations, using heterogeneous populations of brown trout exposed to an emerging pathogen in metal contaminated areas due to historic and contemporary mining activities. This project will offer a novel conceptual framework to elucidate the environmental, physiological and genetic determinisms of variations in resistance/tolerance to stressors, and improve our ability to predict the effects of pollution on wildlife health and emerging diseases.
