Woodland Caribou demographic data and range boundaries

Craig DeMars, Stan Boutin, Robert Serrouya, Sophie Gilbert, Allicia Kelly, Nicholas Larter & Dave Hervieux
As global climate change progresses, wildlife management will benefit from knowledge of demographic responses to climatic variation, particularly for species already endangered by other stressors. In Canada, climate change is expected to increasingly impact populations of threatened woodland caribou (Rangifer tarandus caribou) and much focus has been placed on how a warming climate has potentially facilitated the northward expansion of apparent competitors and novel predators. Climate change, however, may also exert more direct effects on...

Data from: Resource exploitation collapses the home range of an apex predator

Melanie Dickie, Robert Serrouya, Avgar Tal, Philllip McLouglin, Scott McNay, Craig DeMars & Stan Boutin
Optimizing energy acquisition and expenditure is a fundamental trade-off for consumers, strikingly reflected in how mobile organisms use space. Several studies have established that home range size decreases as resource density increases, but the balance of costs and benefits associated with exploiting a given resource density is unclear. We evaluate how the ability of consumers to exploit their resources through movement (termed “resource exploitation”) interacts with resource density to influence home range size. We then...
