echinococcus granulosus in gray wolves and ungulates in idaho and montana, usa.	we evaluated the small intestines of 123 gray wolves (canis lupus) that were collected from idaho, usa (n=63), and montana, usa (n=60), between 2006 and 2008 for the tapeworm echinococcus granulosus. the tapeworm was detected in 39 of 63 wolves (62%) in idaho, usa, and 38 of 60 wolves (63%) in montana, usa. the detection of thousands of tapeworms per wolf was a common finding. in idaho, usa, hydatid cysts, the intermediate form of e. granulosus, were detected in elk (cervus elaphus), mule deer ( ...	2009	19901399
a novel assessment of population structure and gene flow in grey wolf populations of the northern rocky mountains of the united states.	the successful re-introduction of grey wolves to the western united states is an impressive accomplishment for conservation science. however, the degree to which subpopulations are genetically structured and connected, along with the preservation of genetic variation, is an important concern for the continued viability of the metapopulation. we analysed dna samples from 555 northern rocky mountain wolves from the three recovery areas (greater yellowstone area, montana, and idaho), including all ...	2010	20723068
meta-analysis of relationships between human offtake, total mortality and population dynamics of gray wolves (canis lupus).	following the growth and geographic expansion of wolf (canis lupus) populations reintroduced to yellowstone national park and central idaho in 1995-1996, rocky mountain wolves were removed from the endangered species list in may 2009. idaho and montana immediately established hunting seasons with quotas equaling 20% of the regional wolf population. combining hunting with predator control, 37.1% of montana and idaho wolves were killed in the year of delisting. hunting and predator control are wel ...	2010	20927363
cadmium, copper, iron, and zinc concentrations in kidneys of grey wolves, canis lupus, from alaska, idaho, montana (usa) and the northwest territories (canada).	cadmium, copper, iron, and zinc levels were measured in the kidneys of 115 grey wolves (canis lupus) from idaho, montana and alaska (united states), and from the northwest territories (canada). no significant differences in the levels of iron or copper were observed between locations, but wolf kidneys from more northern locations had significantly higher cadmium levels (alaska > northwest territories > montana ≈ idaho), and wolves from alaska showed significantly higher zinc than other locations ...	2010	20972865
restoration of genetic connectivity among northern rockies wolf populations.	probably no conservation genetics issue is currently more controversial than the question of whether grey wolves (canis lupus) in the northern rockies have recovered to genetically effective levels. following the dispersal-based recolonization of northwestern montana from canada, and reintroductions to yellowstone and central idaho, wolves have vastly exceeded population recovery goals of 300 wolves distributed in at least 10 breeding pairs in each of wyoming, idaho and montana. with >1700 wolve ...	2010	21040035
use of linkage mapping and centrality analysis across habitat gradients to conserve connectivity of gray wolf populations in western north america.	centrality metrics evaluate paths between all possible pairwise combinations of sites on a landscape to rank the contribution of each site to facilitating ecological flows across the network of sites. computational advances now allow application of centrality metrics to landscapes represented as continuous gradients of habitat quality. this avoids the binary classification of landscapes into patch and matrix required by patch-based graph analyses of connectivity. it also avoids the focus on deli ...	2012	22010832
effects of breeder turnover and harvest on group composition and recruitment in a social carnivore.	breeder turnover can influence population growth in social carnivores through changes to group size, composition and recruitment. studies that possess detailed group composition data that can provide insights about the effects of breeder turnover on groups have generally been conducted on species that are not subject to recurrent annual human harvest. we wanted to know how breeder turnover affects group composition and how harvest, in turn, affects breeder turnover in cooperatively breeding grey ...	2017	28555834
