First Acoustic Records of the Brazilian Free-Tailed Bat (Tadarida brasiliensis) In British Columbia
This study reports the1st evidence of the Brazilian Free-tailed Bat (Tadarida brasiliensis) in Canada. The historic distribution records of this species was in the Pacific Northwest region of North America including southern Oregon and southern Idaho, but not British Columbia. During 2014–2016 they conducted bat acoustic surveys in Canada on Salt Spring Island, British Columbia, sampling 1342 detector-nights. They recorded multiple bat-call sequences during 2016 showing pulse and sequence attributes consistent with those of the Brazilian Free-tailed Bat. The Brazilian Free-tailed Bat is a fast long-distance flyer, and acoustic surveys outside of its historic range may benefit from surveillance for this species.

Wolverine habitat selection in response to anthropogenic disturbance in the western Canadian boreal forest
This study evaluated alternative hypotheses that anthropogenic disturbance can attract versus displace wolverines (Gulo gulo luscus). Radiotelemetry was used to track wolverine habitat use over three years in the boreal forests of northwestern Alberta. They used resource selection functions (used/available design) to analyze wolverine habitat selection patterns during summer and winter seasons.

Securing a Wild Future - Planning for Landscape-Scale Conservation of Yukon's Boreal Mountains
The cumulative effects of unplanned development can result in the piecemeal erosion of ecological values, with significant impacts on wildlife populations. The capacity of Yukon's Boreal Mountains to accommodate additional growth of the development footprint before ecological values and traditional economies are significantly compromised is unknown. Just a single road through a large, continuous block of intact habitat opens an area up to further resource use, wildlife exploitation, land conversion, motorised and non-motorized recreation, and continued expansion of the road network. This study examines the gaps in existing protection and opportunities and priorities for proactive landscape-scale conservation across approximately 290,000 square kilometres of the southern Yukon using the BEACON’s benchmarking modelling approach.

Ungulate predation and ecological roles of wolves and coyotes in eastern North America
Understanding the ecological roles of species that influence ecosystem processes is a central goal of ecology and conservation biology. Eastern coyotes have ascended to the role of apex predator across much of eastern North America since the extirpation of wolves and there has been considerable confusion regarding their ability to prey on ungulates and their ecological niche relative to wolves. This study investigated intrinsic and extrinsic influences on per capita kill rates of white-tailed deer and moose during winter by sympatric packs of eastern coyotes, eastern wolves, and admixed canids in Ontario, Canada to clarify the predatory ability and ecological roles of the different canid top predators of eastern North America.

Capacity shortfalls hinder the performance of marine protected areas globally
Marine protected areas (MPAs) are increasingly being used globally as a tool to conserve marine resources. However, the extent to which MPAS areeffectively managed and how management influences conservation outcomes have not been investigated. This study composed a global database of management and fish population data to asses: MPA management processes; the effects of MPAs on fish populations; and relationships between management processes and ecological effects.

BIG ANIMALS and SMALL PARKS - Implications of Wildlife Distribution and Movements for Expansion of Nahanni National Park Reserve
This WCS report describes the ‘boundary problem’ of Nahanni National Park Reserve in the Northwest Territories of Canada where it’s small size and narrow shape presents a challenge for protection of wide ranging species. Surveys were conducted on the distribution and seasonal movements of grizzly bears, Dall’s sheep, and woodland caribou to inform decisions on park expansion and land use planning.

Carnivores and Corridors in the Crowsnest Pass
This Alberta Species at Risk Report examines the habitat use and movements of grizzly bears and cougars in the Crowsnest Pass of southern Albert, a region with high habitat fragmentation due to human land uses.

Caribou and the North - A Shared Future
The book explores the reason for the interlinked fate of caribou and the North, as it relates to migratory tundra caribou, boreal forest caribou, and mountain caribou in Canada and the U.S. Climate change coupled with widespread oil, gas, and mineral development adds new pressure for the region’s iconic wildlife.

Dead or alive - animal sampling during Ebola hemorrhagic fever outbreaks in humans
This article provides guidelines for identifying animal sources of disease outbreaks, specifically sources of Ebolavirus (EBOV) during outbreaks of human Ebola hemorrhagic fever (EHF). Guidance is given on sampling animals when resources are limited, when targeting specific species, and when rapid diagnosis of EBOV in animal reservoirs is necessary.

Lynx Survey in the Adirondack Park
This article describes a survey to determine whether there is a population of Canada lynx within the area around the High Peaks region of the Adirondacks. The survey involved a non-invasive technique using the natural cheek-rubbing behavior of cats for hair collection and DNA analysis. This was a follow-up survey to the release of 83 translocated lynx by a team of biologists from SUNY ESF in the late 1980's.
