| morphological variability and molecular identification of uncinaria spp. (nematoda: ancylostomatidae) from grizzly and black bears: new species or phenotypic plasticity? | the hookworms uncinaria rauschi olsen, 1968 and uncinaria yukonensis ( wolfgang, 1956 ) were formally described from grizzly ( ursus arctos horribilis) and black bears ( ursus americanus ) of north america. we analyzed the intestinal tracts of 4 grizzly and 9 black bears from alberta and british columbia, canada and isolated uncinaria specimens with anatomical traits never previously documented. we applied morphological and molecular techniques to investigate the taxonomy and phylogeny of these ... | 2015 | 25548982 |
| first report of taenia arctos (cestoda: taeniidae) from grizzly (ursus arctos horribilis) and black bears (ursus americanus) in north america. | the cestode taenia arctos was found at necropsy in the small intestine of a grizzly (ursus arctos horribilis) and a black bear (ursus americanus) from kananaskis country in southwestern alberta, canada. the autolysis of the tapeworm specimens precluded detailed morphological characterization of the parasites but molecular analysis based on mitochondrial dna cytochrome c oxidase subunit 1 gene confirmed their identity as t. arctos. this is the first report of t. arctos from definitive hosts in no ... | 2014 | 24382413 |
| human perspectives and conservation of grizzly bears in banff national park, canada. | some conservation initiatives provoke intense conflict among stakeholders. the need for action, the nature of the conservation measures, and the effects of these measures on human interests may be disputed. tools are needed to depolarize such situations, foster understanding of the perspectives of people involved, and find common ground. we used q methodology to explore stakeholders' perspectives on conservation and management of grizzly bears (ursus arctos horribilis) in banff national park and ... | 2012 | 22594593 |
