A member of the Conservation Ecology research group of cE3c, Bruno Carreira conducted a Ph.D. in Ecology under the supervision of Doctor Rui Rebelo (University of Lisbon) and Doctor Anssi Laurila (Uppsala University).
Working within the field of Metabolic Theory of Ecology (MTE), this researcher investigates temperature effects on the feeding preferences of ectotherms, bridging Climate Change and Diet Change by studying the effects of extreme climatic events (heat waves) on the assimilation of animal and plant diets.
In the forefront of climate change biology, this research revealed temperature-dependent changes in the relative quality of animal and plant diets and adaptive shifts towards a greater assimilation of plant diets during heat waves, most likely due to increased herbivory at higher temperatures. The discovery of such a relationship between temperature provides additional support to the MTE and contributes to a better understanding of the potential ecological impacts of climate change.
Mostly experimental, the research uses native and alien invasive freshwater ectotherms commonly found in Mediterranean Temporary Ponds in the SW of Portugal, which serve as model systems to study the effects of climate change in wetlands.
