Differentiating the Lévy walk from a composite correlated random walk - Data
2015
Lewis, Mark A., Auger-Méthé, Marie, Plank, Michael J., Codling, Edward A., Derocher, Andrew E.
This the data associated with the manuscript entitled: Differentiating the Lévy walk from a composite correlated random walk. It is the step lengths and turning angles of two bears collared in the Hudson Bay. The data is the step length and turning angle measured at regular time intervals (every...

Allee effects are an important component in the population dynamics of numerous species. Accounting for these Allee effects in population viability analyses generally requires estimates of low-density population growth rates, but such data are unavailable for most species and particularly...

Recent literature on plant population spread advocates quantification of long-distance dispersal (LDD). These estimates could provide insights into rates of migration in response to climate change and rates of alien invasions. LDD information is not available for parameterization of current...

Small-scale vertical aerial photographs taken in 1947 and 1948 covering 200 km2 of the Kluane Ranges, southwest Yukon, were compared with corresponding photographs taken in 1989 for the purpose of characterizing changes in the distribution and abundance of white spruce (Picea glauca (Moench)...

Fatty acid composition of the adipose tissue of polar bears and of their prey: ringed seals, bearded seals and harp seals
Download2003
Grahl-Nielsen, O., Lydersen, C., Wiig, Ø., Kovacs, K., Derocher, A.E., Andersen, M.
Polar bears Ursus maritimus are predators of phocid seals, but they also forage opportunistically on a variety of other species. In the Barents Sea—Svalbard area, their diet is thought to consist almost exclusively of ringed seals Phoca hispida, bearded seals Erignathus barbatus and harp seals P....

Two instances of infanticide and cannibalism in polar bears (Ursus maritimus) were observed in SE Svalbard, at Hopen Island. In the first, an adult male killed three young cubs at a den site and consumed one of them. In the second, an adult male actively pursued, killed, and consumed a dependent...

Planktonic and Epipelic Algal Communities and their Relationship to Physical and Chemical Variables in Alpine Ponds in Banff National Park, Canada
Download2005
McMaster, N. L., Schindler, D. W.
We surveyed 14 ponds in 1999 and 28 ponds in 2000 to better understand the basic limnology of alpine ponds and to predict how the planktonic and epipelic (sediment-living) algal communities may respond to nutrient deposition and climate change. Based on nitrogen to phosphorus ratios, nitrogen...
