David Wardle(brief bio) David Wardle works as a Professor of Soil and Plant Ecology, and his research explores the links between aboveground and belowground communities and their consequences for ecosystem functioning. Much of his research is field based, and includes work in Swedish boreal forest and subarctic tundra, and forests in New Zealand, Australia and elsewhere. Current projects focus on  ecosystem impacts of invasive biota; consequences of wildfire; ecological changes across successional, retrogressive and elevational gradients; aspects of island ecology; and the ecological role of forest understory vegetation. He has authored two books on aboveground-belowground linkages (published by Princeton University Press in 2002 and Oxford University Press in 2010), and around 230 publications of which around 20 have appeared in Science and Nature. He serves or has served on several editorial boards (including Science, Ecology and Ecology Letters), has been designated as a highly cited scientist and as among the world’s 20 most cited scientists in ecology and environmental sciences, and is an elected Fellow of the Royal Society of New Zealand and a Wallenberg Scholar.
