Biogeography and designatable units of Bombus occidentalis Greene and B. terricola Kirby (Hymenoptera: Apidae) with implications for conservation status assessments

Autor: Syd Cannings, Paul H. Williams, Hien T. Ngo, Leif L. Richardson, Jennifer Heron, Cory S. Sheffield

Publikováno v: Journal of Insect Conservation. 20:189-199

Conservation action for species of concern requires that “designatable units” (e.g., species, subspecies, geographic races, genetically distinct forms) are clearly defined, or that the species complex is treated as a whole. Several species of bum
