Past Visiting Ecologists

The School of Forest Resources and Environmental Science has welcomed many extraordinary ecologists to its Distinguished Ecologist Series. These past speakers embody the integrity of this series and we hope will encourage you to attend this year's series of lectures by distinguished ecologists.


Peter Hogberg — September 29, 2011

Professor in Soil Science, Head of the Forest Ecology and Management department at SLU, Umeå, Sweden

Broadly, Dr. Högberg’s research concerns the cycles of nitrogen and carbon through forests, especially interactions among trees, mycorrhizal fungi, and soils.  Through novel applications of whole-ecosystem carbon and nitrogen isotopic labeling experiments, as well as tree girdling experiments, Dr.Högberg and colleagues have contributed tremendous insight as to how forests allocate resources, and how this affects the cycling of nutrients in the ecosystem.


Harri Vassander — October 6, 2011

Professor in Peatland Forestry; Department of Forest Sciences; University of Helsinki

Dr. Vasander is broadly interested in peatland classification, production, and C dynamics of boreal and tropical peatlands.In addition to an extensive peer-reviewed publication record, he is also co-author to many instructional and field identification guides, including, “The Intricate Beauty of Sphagnum Mosses – a Finnish Guide to Identification”. 


Green Fire - October 20, 2011 at 7 p.m. in G002 U.J. Noblet Forestry Bldg. 

The first full-length, high-definition documentary film ever made about legendary environmentalist Aldo Leopold, Green Fire highlights Leopold’s extraordinary career, tracing how he shaped and influenced the modern environmental movement. Leopold remains relevant today, inspiring projects all over the country that connect people and land.http://www.greenfiremovie.com/

Aldo Leopold, Phenology and Climate Change --- 11:00a.m. in the room 146 (the wildlife teaching lab)

Aldo Leopold, best known as the author of A Sand County Almanac, was a keen observer of the natural world. Throughout his life he kept daily journals recording observations of seasonal events, especially those occuring at his beloved "shack" on the Leopold farm which was the setting for many essays in A Sand County Almanac. Leopold's meticulous phenological observations have provided us with an unparalleled record of when plants bloomed, birds migrated and other natural events. Comparing his observations of hundreds of natural events to recent records helps us understand how climate change is affecting the ecological community. One lesson of Leopold's journals is clear: For those who love nature and take time to observe it closely, keeping records enhances the enjoyment and value of our time and effort, both now and in the future.

Things I've learned: Insights from a 40-year Career in Conservation --- 4:00p.m. in the room 146 (the wildlife teaching lab)

Find out how an early interest in birds lead to a childhood friendship with Rachel Carson, helping write the Endangered Species Act, developing recovery programs some of the world's rarest species, preserving some really important natural areas, helping launch the field of conservation biology, and walking in Aldo Leopold's footsteps. And along the way there were the near-death experiences, the CIA connection, skirmishes with the World Bank, hate mail from animal-rights activists, and other assorted side stories.


Oswald J. Schmitz — October 27, 2011

Oastler Professor of Population and Community Ecology; Yale School of Forestry and Environmental Studies; Yale Department of Ecology and Evolutionary Biology

Professor Schmitz’s research examines the dynamics and structure of terrestrial food webs. His specific focus is on plant-herbivore interactions and how they are shaped by carnivores and soil-nutrient levels, both at the level of herbivore foraging ecology and plant-herbivore population dynamics. He is also examining how natural systems are resistant and resilient to natural and human-induced disturbances. His approach involves developing mathematical theories of species interactions in food webs and testing these theories through field experiments. The work deals with a variety of ecosystems and herbivore species, ranging from moose deer and snowshoe hare in northern Canadian forests to insects in New England old-field ecosystems.


Virginia Dale — November 11, 2011 

Landscape Ecology & Regional Analysis Group, Oak Ridge National Laboratory; Adjunct professor at the University of Tennessee

Dr. Dale’s primary research interests are in a landscape design for bioenergy, environmental decision making, land-use change, landscape ecology, and ecological modeling. She has worked on developing tools for resource management, vegetation recovery subsequent to disturbances; effects of climate change on forests; and integrating socioeconomic and ecological models of land-use change.Her current research involves working closely with resource managers to identify indicators of ecological change at different scales and to design models that can project regional changes in environmental conditions.
