Population Genetic Structuring of the Lesser Prairie-chicken
The goals of this study are to characterize patterns of connectivity across the Lesser Prairie-chicken range, document levels of genetic variability among populations, identify the source population(s) for the region of recent range expansion, and determine the level of introgression with the Greater Prairie-chicken in areas where the two species overlap in distribution. This project is revealing relatively strong population structure that falls largely along ecoregion boundaries. This study also shows that the species is expanding its range into previously unoccupied or sparsely occupied habitat from the mixed grass prairie ecoregion and to a lesser extent from the sand sagebrush ecoregion (due to enrollment of agricultural land into the Conservation Reserve Program) and is actively hybridizing with Greater Prairie-chickens in the area of expansion, information that is highly relevant for management. This research is in collaboration with Texas A&M-Kingsville, Oregon State University, University of North Texas, University of Oklahoma, and the Sutton Avian Research Center.
