Fernando Chaguaceda
My postdoctoral project aims to assess and predict changes in Arctic freshwater biodiversity and food webs under rapid environmental change. I will use controlled lab experiments mixed with large-scale field studies and I will collaborate with an international group of experts from North American and Scandinavian universities.


I am a Postdoc interested in the effects of environmental change on freshwaters from individuals to ecosystems. During my PhD, I investigated how environmental change affect the resource-driven (bottom-up) and predator driven (top-down) control in lake food webs. Here at SLU, I will study the effects of rapid environmental change in Arctic freshwater ecosystems on their food webs and biodiversity. In addition, I am interested in how environmental change affects the food and nutrient linkages across habitat and ecosystem boundaries, which can lead to food-web reconfigurations (AKA "rewiring") across the landscape.
