  1. Development of variable microsatellite loci and range-wide characterization of nuclear genetic diversity in the important dryland shrub antelope bitterbrush (Purshia tridentata)

    Antelope bitterbrush (Purshia tridentata Pursh DC; Rosaceae) is an arid-land shrub that occupies an important ecological niche in various fire-dominated communities across much of the Western United States. Because of its importance as a browse for large mammals and a food source for granivores, P. tridentata is frequently planted...

  2. Breeding system and interaccessional hybridization of Purshia tridentata plants grown in a common garden

    Purshia spp. (Rosaceae) comprise a widespread western North American species complex that is important as landscape dominants, wildlife habitat, browse for wild and domestic ungulates, and seed reserves for small mammals. This study examined aspects of the phenology, compatibility, pollination biology, and progeny fruit characteristics of multiple accessions of...

  3. Food habits of Pacific Marten from scats in south-central Oregon

    Quantifying prey taken by Pacific Marten (Martes americana caurina) helps to understand local habitat requirements of the species. We collected 250 scat samples associated with at least 53 marten in a salvage-logged Lodgepole Pine (Pinus contorta)-Bitterbrush shrub (Purshia tridentata) forest in south-...
