Resumen:
M.E. BARRANTES Y M.E. Lattuca CONTRIBUYERON EN IGUAL MEDIDA A LA REALIZACIÓN DEL TRABAJO, POR LO TANTO AMBAS SON CONSIDERADAS PRIMERAS AUTORAS (VER PDF DE LA PUBLICACIÓN).The native freshwater fish Galaxias platei shows a wide latitudinal distribution in Patagonia, being found on both sides of the Andes. Currently, climate change poses one of the main threats to native fish, and its effects are appearing faster in high southern latitudes. The aim of this work was to analyse the possible effects of climate change in G. platei through its thermal responses. We hypothesized that juveniles of this species would be affected by indirect rather than by direct consequences of climate change. We determined the thermal tolerance polygon using Critical Thermal Methodology and preferred temperatures using a thermal gradient. Additionally, we evaluated routine metabolic rate using stop-flow respirometry.
