Research Interests: population genetics; conservation biology; herpetology.
Dr. Gonser's primary research interests focus on conservation of species due to loss of suitable habitat and continuing habitat fragmentation. More specifically, he studies proximate and ultimate aspects affecting population structure. This includes such factors as behavior, ecology, and evolution. Dr. Gonser is currently studying gene flow and genetic diversity of the white-tailed deer, Odecoiles virginianus. White-tailed deer have a large, ubiquitous geographic distribution and are important to the North American ecosystem, as well as the economy. He is investigating the genetic structure of a reproductively isolated population of white-tailed deer in southern Maryland using mitochondrial DNA sequence. This population was originally colonized from a few individuals from Virginia.
Dr. Gonser's previous work examined the genetic structure of the Puerto Rican frog, Eleutherodactylus coqui, using molecular and behavioral techniques. He found that coquíes from eastern Puerto Rico are distinctly different than coquíes from western Puerto Rico, indicating that the two populations have become isolated over recent evolutionary time. As part of this research, Dr. Gonser developed a technique for the use of amphibian toe-clips as important sources of genetic information (e.g. DNA sequence), which can be collected without detrimental effects on the population.
Dr. Gonser (in collaboration with Dr. Elaina Tuttle) studies White-throated Sparrows. This long-term project examines how ecology, behavior, genetics, and physiology maintain natural variation through their influence on the evolution of life-history strategies, phenotypic expression, and both the relative fitness and frequency of genotypes within a population. This project focusses on the maintenance of polymorphism via disassortative mating in the white-throated sparrow (Zonotrichia albicollis). The work on white-throated sparrows examines how individuals maximize fitness through the differential allocation of time, energy, and resources. Questions address how individuals balance various life history trade-offs, and how life-history trade-offs generate variance that affects the evolution of sexually-selected characters. The research differs from many conventional evolutionary study as it employs concepts and techniques borrowed from other areas of biology. This research uses observational and experimental methods in the field and laboratory, molecular genetic techniques (e.g. minisatellite DNA fingerprinting, microsatellites, RAPDs, AFLPs), physiological techniques (e.g. semen sampling, hormonal analyses, and immunological analyses), and other multi-disciplinary techniques (e.g. karyotyping, histology). An integrative approach often reveals new alternative hypotheses and allows investigation of evolutionary questions at proximate and ultimate levels.
