Research Specializations

Graduate-degree candidates conduct research under the guidance of the School of Biology and Ecology faculty. The expertise of the faculty covers a broad spectrum, ranging from molecular and cell biology, through system- and organism-level biology, to ecology; and it applies to a diversity of organisms from protists and lower plants and invertebrate animals through vascular plants and vertebrates. By choosing a faculty advisor, graduate applicants can associate themselves with any of a number of research specializations:

Animal Behavior and Behavioral Ecology, including chronobiology, feeding behavior, foraging, host plant selection, reproductive behavior, behavior and endocrinology of birds, migration and predator-prey interactions.

Applied Biology, including biological control and insect pest management, fisheries, and plant pathology.

Botany, Plant Biology, Mycology, including plant and fungal systematics, molecular and morphological phylogeny, reproductive biology, quantitative morphology, molecular basis of plant responses to the environment; plant ecology, marine algal ecology, plant paleoecology, microscopy of zoosporic fungi, mycology, and physiology and molecular biology of fungal pathogens.

Developmental and Cell Biology, including cell and molecular biology of muscle development, biology, developmental genetics, embryology, cardiac pacemaker mechanisms, and neurobiology.

Ecology Environmental Biology, and Paleoecology, including aquatic, community, insect and plant ecology; biogeochemistry; biodiversity; conservation biology; paleolimnology population dynamics; population modeling; and Quaternary paleoecology.

Entomology, including insect ecology and biodiversity, insect pathology, biological control and insect pest management, ecology of aquatic insects, and predator- prey interactions, pollination ecology, computer simulation of insect population dynamics.

Fisheries Biology, including ecology and behavior of fishes, fish microevolution and population ecology, salmonid biology, and aquaculture.

Freshwater Biology, including toxicology, ecology and behavior of fishes, lake, stream and river ecology, and paleolimnology.

Plant Pathology, including control of fungal pathogens, and pest management.

Physiology and Physiological Ecology, including environmental physiology of marine invertebrates, fungal physiology, insect-plant interactions, pathogen-plant interactions, endocrine physiology and systemic physiology.

Science Education, Including course and program assessment and developing innovative instructional techniques.

Systematics and Evolution, including microevolution, phylogenetics of plants, fungi, invertebrates, and fishes, and comparative morphology.

Special Options

The School is also associated with the Institute for Quaternary and Climate Studies with which students may arrange cooperative programs of study.

Students of genetics may choose, as an option, study in a Ph.D. program on mammalian genetics offered in cooperation with The Jackson Laboratory. Thesis work may be conducted at The Jackson Laboratory; the doctorate is awarded by the University.

Training in applied fishery science is provided through the Maine Cooperative Fish and Wildlife Research Unit, operated at the University under an agreement among the University, the Biological Resources Division of the U. S. Geological Survey, the Wildlife Management Institute, and the Maine Department of Inland Fisheries and Wildlife. Also, the Migratory Fish Research Institute supports basic research on fishes.


Key to the School’s research efforts are several facilities providing equipment, space and professional personnel. Among equipment available for graduate-student use, for example, are automated DNA-sequencing equipment, laser confocal and electron microscopes, digital imaging equipment, gas liquid chromatographs, scintillation counters and controlled-environment chambers. Aquatic laboratories for raising fishes and invertebrates, greenhouses, The University of Maine herbarium, an on-campus arboretum, and numerous sites for field research on both managed and natural habitats in marine, freshwater, and terrestrial ecosystems are easily accessible. Sites managed by the Maine Agricultural and Forest Experiment Station include the Blueberry Hill Research Farm in Jonesboro, the Organic Blueberry Research Site in Whitneyville, the Aroostook Potato Research Farm in Presque Isle, The Rogers Sustainable Agriculture Research Farm in Stillwater, and the Demeritt and Penobscot Experimental Forests in Orono and Bradley. Marine research facilities are available through the University’s Ira C. Darling Center at Walpole, Maine; through the Huntsman Marine Science Center at St. Andrews, New Brunswick, Canada; and through the Mount Desert Island Biological Laboratory at Salsbury Cove, Maine. In affiliation with the Institute for Quaternary and Climate Studies, the department operates the Laboratory for Paleoecology and Paleohydrology. The Molecular Forensics Laboratory in Murray Hall provides DNA analysis for the Maine Warden Service and other wildlife enforcement agencies.


Applicants are encouraged to identify an area of research interest and a potential advisor at the time of application; they should feel free to contact members of the faculty to discuss possible research projects even before submission of the application. A research project is a central part of both the M.S. and Ph.D. degrees.

All applicants will be automatically considered for teaching or research assistantships. Many students are supported by research grants to individual faculty members; interested students should contact faculty members directly for further information on grant-supported assistantships.
