An adaptive approach to endangered species recovery based on a management experiment: reducing moose to reduce apparent competition with woodland caribou
DownloadFall 2013
Species that are rare yet widely distributed are among the most challenging to conserve. The mountain ecotype of woodland caribou (Rangifer tarandus) is declining because of apparent competition with non-caribou ungulates (NCU) such as moose (Alces alces). I experimentally assessed whether...

Breebaart, L., St. Louis, V.L.
We quantified supplemental sources of calcium in the diet of nestling Tree Swallows (Tachycineta bicolor) near acid sensitive lakes in northwestern Ontario. Among the calcium-rich items brought to nest boxes by adult swallows and ingested by nestlings, fish bones (particularly flat pieces) were...

Fall 2013
Caribou (Rangifer tarandus L.) populations in Canada are threatened by climate change and anthropogenic landscape disturbance, which may negatively affect caribou energetics and range occupancy, with negative consequences for vital rates. Caribou are the basis of economy and spirituality for...

Density-dependent variation in lifetime breeding success and natural and sexual selection in Soay rams
Download1999
Smith, J.A., Bancroft, D.R., Clutton-Brock, T.H., MacColl, A.D., Pilkington, J., Coltman, D.W., Pemberton, J.M.
Variation in male lifetime breeding success (LBS) is central to understanding selection, yet it has rarely been measured in natural populations of large mammals. Here, we first describe variation in the opportunity for selection in cohorts of Soay rams (Ovis aries) on the archipelago of St....

EFFECTS OF CLIMATE CHANGE, VEGETATION AND ROADS ON CARIBOU DISTRIBUTION IN WESTERN NORTH-AMERICA
DownloadFall 2017
Caribou (Rangifer tarandus) are a vital component of the cultural history and contemporary existence of First Nations and northern communities. However, caribou habitat is increasingly threatened by cumulative effects of climate change and land-use pressures from human settlement, forestry, and...

Let the winter sun shine on, let me feel the frost of dawn: Rangifer tarandus osteology, anatomy, and identity
DownloadFall 2020
Rangifer tarandus, the species which encompasses both caribou in North America and reindeer in Eurasia, is a keystone species for both the cultures and the ecosystems of the circumpolar world. Because of this, human interactions with reindeer and caribou throughout history are of great interest...

Measuring wildlife response to seismic lines to inform land use planning decisions in northwest Canada
DownloadFall 2012
Development of hydrocarbon resources across northwest Canada has spurred economic prosperity but also generated concerns over impacts to biodiversity. To balance these interests, comprehensive land use plans have been used to match targeted management strategies to ecological components deemed...

Seasonal patterns of mortality for boreal caribou (Rangifer tarandus caribou) in an intact environment
DownloadSpring 2020
Seasonality is an important component in shaping the dynamics that influence ecosystems, including mortality. Animals experience temporal variation in vulnerability to mortality due to interactions among environmental conditions, nutritional condition, age and life stages, and changes in their...

Short-Term Effects of Timber Harvest on Abundance, Territory Characteristics, and Pairing Success of Ovenbirds in Riparian Buffer Strips
Download2000
Hannon, Susan, J., Lambert, J. Daniel
In managed forests, riparian buffer strips typically are maintained to protect water quality. If properly designed, buffer strips also may act as wildlife reserves. However, forest managers have lacked the information to develop standards for buffer strips to maximize benefits for wildlife...

Trees Wanted - dead or alive! Host selection and population dynamics in tree-killing bark beetles
Download2011
Erbilgin, N., Gregoire, J. C., Gilbert, M., Kausrud, K. L., Skarpaas, O., Stenseth, N. C., Okland, B.
Abstract: Bark beetles (Coleoptera: Curculionidae, Scolytinae) feed and breed in dead or severely weakened host trees. When their population densities are high, some species aggregate on healthy host trees so that their defences may be exhausted and the inner bark successfully colonized, killing...
