Our research focuses primarily on avian conservation biology, primarily at the level of populations and species. By using a combination of both field- and lab-based research, we address questions assessing life history constraints and population viability. For example, we use genetic data such as DNA sequences or genotypic frequency data (i.e., microsatellite DNA, SNPs) with data obtained from the field to identify evolutionary relationships among taxa or populations to help facilitate in their conservation and maintain viable populations.
Human mediated changes in landscape over a relatively short amount of time (e.g., <100 years in North America; see the Millennium Ecosystem Assessment) have placed considerable pressure on a large number of populations. Our research identifies demographic factors, or processes, which have helped shape the biology of a species or population of interest. Combining knowledge of geographic distribution and ecology, historical and current, we can be of assistance by making recommendations in helping preserve natural systems by identifying correlations between genetic differentiation and aspects of biology such as habitat requirements, behavioral limitations, breeding system, seasonal movements, and morphological characteristics. In addition, evolutionary relationships unique to a particular lineage, which may not be obvious from the exterior (phenotype), can be identified using genetic methods, and, depending on its distinctiveness, may require specific conservation efforts in order to prevent extinction.
Current research primarily addresses conservation issues related to grouse (Family: Phasianidae) and birds of prey (Families: Falconidae, Accipitridae, Cathartidae), and on occasion we have been known to work on projects focused on other taxa, including mammals and arthropods. We work directly with both government and nongovernmental organizations to help incorporate current genetic and ecological-based methods into active conservation efforts.
In our research we often utilize tissue samples collected from contemporary populations; however, due to difficulties in obtaining adequate sample sizes or collecting rare taxa in geographically inaccessible localities, we also employ tissues obtained from museum specimens for DNA extractions. Some of these projects would not have been possible without access to museum specimens, and such studies further demonstrate the absolute importance of museum collections in helping inventory biodiversity and aiding in conservation.
