Biology talk features U-Wisconsin Madison scientist Chemical Ecology of Populus: a "genes to ecosystem" perspective, will be presented by Richard Lindroth, University of Wisconsin-Madison, at noon Friday, Feb. 13, in Starcher Hall, Room 141. Dr. Lindroth received his Ph.D. from the University of Illinois (Urbana), and is currently a Professor in the Department of Entomology at the University of Wisconsin-Madison, where he has been a faculty member since 1988. In describing his research, Dr. Lindroth states, "At the broadest level, research conducted by my group addresses the roles of mechanisms that underlie ecological interactions at levels spanning the range from biochemistry to ecosystems. We are particularly interested in how plant chemistry influences: 1) interactions among plants, herbivores, and natural enemies, and 2) ecosystem dynamics such as decomposition and nutrient cycling. Other, nonchemically-oriented work addresses environmental impacts on trophic cascades and insect biodiversity. Our research focuses on northern temperate forest species (aspen, maple, birch) and western riparian species (cottonwood), although some studies address herbaceous systems. " Hosted by the UND Biology Department. Everyone is welcome.
