Population and Community Biology, Plant-animal interactions, Plant Systematics, Organic Evolution, and Conservation Biology. Population and Community Biology is an introduction to ecology and evolution and is a part of the Biology Department CORE curriculum. The plant-animal interactions course surveys mutualisms, anatagonisms, and commensalisms while stressing field-based, multi-week projects that emphasize pollination biology, herbivore-plant interactions, biotic fruit dispersal, and the ecology of carnivorous plants. The plant systematics course examines systematic theory including cladistics. The laboratory is strongly based in the field and focuses on the Pennsylvania flora. Organic Evolution covers the principles and mechanisms of evolution in plants and animals including population phenomena, speciation, life history strategies, and adaptation. Conservation Biology is a senior capstone course that examines the elements of demography, genetics, economics, and ethics.

Evolutionary Ecology and Conservation Biology. Specifically, plant-insect interactions of three trophic-level interactions using goldenrods, ball gall insects, and natural enemies as well as oaks and cynipid gall insects, speciation of phytophagous insects; the ecology of fire in Florida's upland scrub communities; conservation studies of local natural areas.
As of 1 March 2010, Dr. Abrahamson has published 148 scientific articles and 2 books with the following co-authorship: 42% with student co-authors (28% with undergraduates, 17% with graduate students), and 51% with Postdoctoral Fellows. Abrahamson has hosted 21 Postdoctoral Fellows since 1981. He was elected a Fellow of the AAAS in 2007 in recognition of his contributions to understanding the evolution and ecology of plant-animal interactions.
