BIO 432 Comparative Physiology
Dr. Trier is a comparative physiologist who specializes in the field of nutritional ecology. Dr. Trier has worked on both mammalian and insect physiology and nutritional ecology. At the physiological level, Dr. Trier is interested in how the balance of dietary nutrients can influence the metabolic rate and energy balance of wild herbivores that normally consume diets that are low in nitrogen or other nutrients and therefore "unbalanced." Additionally, he is interested in exploring the underlying physiological mechanisms that facilitate low energy efficiencies that occur when animals consume unbalanced diets.
At the ecological level, Dr. Trier is studying plant-herbivore interactions and plant defense in terms of how plants respond to herbivory by increasing their fiber content and thereby dilute their nitrogen and energy concentrations, making them less desirable as a food source. Additionally, Dr. Trier is studying the effects of anthropogenic pollutants (CO2 and O3) on plants, and the concomitant effects such plants have on the herbivores that consume them.
Dr. Trier is interested in students willing to work in Rhinelander, Wisconsin during the summer, where his greenhouse gas research is based. Dr. Trier is also looking for students that would like to work on insect energetics. This would entail feeding insects leaves and then measuring their performance in terms of growth and efficiency of energy retention. Students working on this project learn bomb calorimetry, digital image analysis, some basic insect ecology, and how to calculate insect nutritional indices and basic statistics.
Dr. Trier is available to mentor students with independent projects in animal physiology. Although physiological projects with an ecological emphasis are preferred, Dr. Trier is willing to work with students on a wide variety of projects in the field of general and comparative animal physiology, nutritional ecology, and general ecology.
