If you are a biology major at Lander, especially if you are one of my advisees, or if you are one of my students, you might wish to visit my advising page.
Though I find all organisms fascinating, I am especially captivated by animals and the lives they lead.
Moreover, I enjoy sharing my interests with students, and some of the courses on my favorites list, in alphabetical order, are:
Comparative Vertebrate Anatomy
I am most interested in the ecological aspects of foraging behavior of
For my M.S. thesis I examined temporal and thermal characteristics of cold-water foraging by northern water snakes, Nerodia sipedon. While foraging in Lake Michigan along the shores of Beaver Island, these water snakes shuttle between the colder waters where they find fish and the warmer waters at the shoreline. This strategy may allow them to remain in the lake to forage for several hours by reducing the amount of time they experience body temperatures low enough to hamper locomotion. ( Here's to being in the right place at the right time.)
For my Ph.D. research, I studied the foraging behavior of Mangrove Saltmarsh Snakes, Nerodia clarkii compressicauda. Specifically, I examined the relative importance of chemical and visual cues in eliciting lingual luring behavior and how light intensity, habitat complexity, and prey density affect the snakes' use of different foraging modes.
