*</sup>Vanessa L. Lougheed () is an Assistant Professor in the Department of Biological Sciences at the University of Texas at El Paso. Her research interests include understanding of the causes and ecological consequences of aquatic ecosystem degradation, particularly the impact of climate change on Arctic tundra ponds. Address: The University of Texas at El Paso, 500 West University Ave., El Paso, TX 79968, USA. e-mail: vlougheed@utep.edu
^**Malcolm G. Butler is a Professor of Biological Sciences at North Dakota State University. He studies aquatic ecology at population, community, and ecosystem levels, with emphasis on the functional roles of invertebrates. Dr. Butler worked on arctic tundra ponds in 1975–1980 and from 2006 to present. Address: Department of Biological Sciences, North Dakota State University, Fargo, ND 58108, USA.
^***Daniel C. McEwen is an Assistant Professor of Biosciences at Minnesota State University of Moorhead. His research interests include seeking to understand temperature dynamics of tundra ponds in the Arctic and how temperature dynamics influence the ecology of organisms associated with these habitats. Address: Department of Biosciences, Minnesota State University Moorhead, Moorhead, MN 56563, USA.
^****John E. Hobbie is a Senior Scholar at the Marine Biological Laboratory in Woods Hole, Massachusetts. His research interests include microbial ecology of plankton and soil bacteria, nitrogen cycling in the arctic tundra and coastal eutrophication.
