Dr. Javier Lobon-Cervia: - Full-time researcher of the Spanish National Research Council since 1986. - Founder and Editor in chief of the international journal ""Ecology of Freshwater Fish"", 1992-2016. - Major Research: Population and community ecology of stream-dwelling fishes, mostly salmonids and (Neo)tropical fish. - Publications: Over 200 articles in international and national journals; served as editor and author for 4 books and 2 books as single author. Phaedra Budy is the Unit Leader of the U.S. Geological Society, Utah Cooperative Fish and Wildlife Unit as well as a Professor of fisheries management and aquatic ecology in the Department of Watershed Sciences at Utah State University (USU). She holds aB.S. in Limnology from the University of California, Davis and a PhD in Aquatic Ecology from Utah State University. In conjunction with her research lab, she does research that fits into an overall framework of evaluating the factors that structure and limit fish populations in both lentic and lotic systems, and they also work broadly in conservation biology, invasion ecology, and aquatic food web dynamics. Her current research covers a wide geographical range including most of Utah, as well as parts of New Mexico, Nevada, and Alaska and includes salmonids, many imperiled native desert fishes, and warm water lentic fishes. She is also involved in experimental stream restoration (with beavers) and large river management. Robert Gresswell is an instructor in the Department of Ecology at Montana State University and Emeritus Research Scientist, U.S. Geological Survey. For over 49 years, he has been studying the factors that influence fish abundance, distribution, and life history within, and among watersheds, and how these relationships change through time. Interest in the role of disturbance in shaping aquatic systems has led to research on the interactions among landscape-scale environmental variables, instream habitat characteristics, and cutthroat trout abundance and distribution. Current investigations are focused on the effects of fire, timber harvest, invasive species, and climate change on persistence of native trout in the western USA.
