Context Human-modified landscapes can structure species’ distributions and supplant traditional biotic range-limiting processes. Understanding the direction and scale of these processes is necessary to enhance species conservation efforts. Objectives We investigated how the distribution of a prairie-obligate carnivore, swift fox (Vulpes velox), is...
The Great Plains region has undergone extensive conversion of native prairies to agriculture production and energy development since European colonization. Temperate prairies, including remaining prairies within the Great Plains, are considered among Earth’s most imperiled ecosystems. Prairie patches now exist as components of a landscape mosaic pr...
Ungulate species have consistently been a major focus of reintroductions to their native ranges. Bighorn sheep (Ovis canadensis) are an ecologically sensitive species, and have experienced population declines throughout their historic range; bighorn sheep inhabited the Black Hills region of South Dakota but were extirpated from the area due to anth...
Bighorn sheep (Ovis canadensis) were once extirpated from the Black Hills region of South Dakota, USA, mirroring declining populations throughout North America. Since the 1960s, several reintroductions have occurred in the Black Hills to reestablish populations with varying success. We translocated 26 bighorn sheep from Alberta, Canada to the Black...
ABSTRACT—Bighorn Sheep (Ovis canadensis) historically inhabited the Black Hills region of South Dakota, but the species was extirpated from the area in the early 1900s concurrent with declines in population throughout their entire North American range. Translocation is a common management tool allowing for accelerated colonization of historic Bigho...
From 2015-2017, we evaluated a newly established bighorn sheep ( Ovis canadensis) herd in the Deadwood Region of the Black Hills, South Dakota. Our objectives were to 1a) determine annual survival rates, 1b) determine cause-specific mortality, 1c) estimate population size, 2a) assess genetic diversity, 2b) assess disease prevalence, 3) evaluate mov...
