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 I love to teach or would love to have the opportunity to teach, in alphabetical order, are:
Animal Behavior
Comparative Vertebrate Anatomy
Ecology
Herpetology
Human Anatomy
Invertebrate Zoology
Mammalogy
Zoology
Vertebrate Zoology
I am most interested in the ecological aspects of foraging behavior of
semiaquatic snakes.
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.
Click here for some video clips of the lingual luring exhibited by these snakes,
including some showing successful attraction and capture of fish.
