Between mid-August and last September, Dr. Marco Cabrerizo, from the University of Granada, Spain, visited the EFPU. Marco is part of the collaborating group of the PICT 2017-0411 project “Effects of global change on the metabolism and trophic interactions of planktonic communities from Patagonian coastal areas” (PI: Dra. Macarena Valiñas). During his stay, we carried out experiments aimed at evaluating the impact of different global change stressors on planktonic communities in Bahía Engaño.
