Elosegi, Arturo
ARTURO ELOSEGI is professor of Ecology at the University of the Basque Country, Spain. His research fi eld focuses on river ecosystem functioning, including nutrient retention, storage and breakdown of organic matter, and whole stream metabolism. He is especially interested in the effects of human activities such as forestry and agriculture on river health, and in the interplay between hydromorphology and ecosystem functioning. He has participated in several restoration projects and collaborates actively with planners, policy makers and managers. SERGI SABATER is professor of Ecology at the University of Girona and senior researcher at the Catalan Institute for Water Research, both based in Girona, Spain. His research interests lie in river structure and functioning, particularly the role that microbial biofi lms play in river ecosystems. He has performed most of his research on Mediterranean river systems, and is especially keen to understand how much they are affected by rising water scarcity, pollution, and other human pressures, all of them impacting on water resources and biodiversity.
