Academic Statement (Return to top)
Mark has been teaching in the Environmental Studies Program at Prescott College since 1988. His courses offer a strong foundation in the biological sciences and combine theory with an experiential emphasis. This is especially the case in his field courses in Mexico and in Costa Rica, but his on-campus courses also include numerous field trips and, in many instances, hands-on laboratory exercises. In all his teaching, he strives to weave together an understanding of ecological principles with evolutionary theory so that students can cultivate an appreciation for the origin and maintenance of biological diversity.

Research (Return to top)
Mark's current research focuses on questions concerning the diversity of avian plumage patterns. Why do similar plumage patterns repeatedly evolve in distantly related lineages while strikingly different plumage configurations may be exhibited in closely related taxa? Why do some species have streaks while others have bars? Is there a relationship between plumage pattern and morphology? Accordingly, he has identified an empirically derived plumage pattern trajectory that covaries with body size and morphology across the Class Aves (see Riegner, 2008). Furthermore, the trajectory is recursive at various taxonomic levels, such as within genera and within families, and thus serves as an indicator of parallel evolution. The recursive nature of the trajectory, in which morphological and chromatic elements recur in modified configurations, has perhaps contributed to an underestimate of parallel evolution in birds.
