The two objectives for this project were to determine what weed species are being...
An intertebrate ecosystem engineer likely covered under the umbrella of sage-grouse conservation
Jason D. Carlisle, David R. Stewart, Anna D. Chalfoun
2017, Western North American Naturalist (77) 450-463
Conservation practitioners often rely on areas designed to protect species of greatest conservation priority to also conserve co-occurring species (i.e., the umbrella species concept). The extent to which vertebrate species may serve as suitable umbrellas for invertebrate species, however, has rarely been explored. Sage-grouse (Centrocercus spp.) have high conservation priority throughout...
