Juan M. Molina is Assistant Professor of Vertebrate Zoology, Fisheries Resources and Aquaculture at Universidad Nacional del Sur, and also researcher at CONICET (National Research Council) in Argentina. His Ph.D. thesis focused on ecology and biology of fish assemblages. He was awarded an Emerging Leaders of the Americas to conduct a research collaboration in field physiology at Carleton University (Canada) as part of his doctoral studies. As postdoc, he was granted a POGO-SCOR visiting fellow to train in ecological modeling at Hokkaido University (Japan), an Endeavor’s Research Fellowship to conduct research on shark metabolism in Monash University (Australia) and an Alexander von Humboldt research fellowship to study climate change implications on fish metabolism at ZMT (Germany) and CCMAR (Portugal). His research revolves around studying fish responses to challenges from their environments and from human activity in order to understand how they deal with these different stressors. Gabriela E. Blasina is Professor of Fisheries Resources at Universidad Nacional del Sur and Researcher at CONICET. She obtained her Ph.D. in Biological Sciences from Universidad Nacional de Mar del Plata (Argentina) in 2013. Her Ph.D. thesis was based on biology and trophic ecology of estuarine fishes. Blasina’s postdoctoral training was completed at Universidad Nacional del Sur. She specialized in Fisheries at Universidad de Cadiz (España). Her professional development focuses on fisheries resources conservation, specifically on topics that cover aspects related to community composition and structure, trophic ecology, ecomorphology, growth and effects of anthropic impact on coastal and estuarine fish species.
