Elizabeth A NewellEmeritus Professor of Biology
Joined faculty in 1988
My research interests are primarily in the area of plant ecology, including physiological ecology, tropical ecology, and agroecology. I'm very interested in how natural selection has shaped the way plants acquire resources and then allocate them to growth, reproduction, defense, or storage.
The most recent research I've done with students has been on local agroecosystems, including the HWS Fribolin Farm. We've been studying the effect of different farm management techniques (organic vs. conventional production; no-till vs. conventional tillage) and crops on soil invertebrates that are critical to nutrient cycling in agricultural soils.
Another local research project compared the physiology of related evergreen and deciduous plant species in a sphagnum bog north of Geneva, a fascinating community type that is now rare in western New York. We have studied the relative allocation of biomass to carnivory vs. carbon gain in pitcher plants (Sarracenia purpurea). Bogs are stressful environments for plants because they are waterlogged and very low in soil nutrients. Being evergreen (as opposed to decidous) and being carnivorous are considered adaptations to bog environments.
Many of my research publications focus on research I’ve done on the physiology of trees and shrubs in the rainforests of Central America.
