A multi-scale test of the forage maturation hypothesis in a partially migratory ungulate population
Download2008
McDermid, G., Hebblewhite, M., Merrill, E.
The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate forage biomass to maximize energy intake...

The boreal ecotype of woodland caribou (Rangifer tarandus caribou) is federally listed as Threatened due to population declines throughout its distribution. High mortality rates of neonate calves (≤ 4 weeks old) due to predation are a key demographic factor contributing to population declines...

Price, M. A., Hudson, R. J., Wairimu, S.
Ten yearling wapiti stags were used to investigate effects of winter nutrition on subsequent growth on summer pasture. One group of five (LOW) was wintered on medium-quality hay, and the other group of five (HIGH) was wintered on hay and alfalfa–barley pellets (16% crude protein). By the time...

In western North America cougar populations are increasing and expanding eastward. Simultaneously, growing human populations are creating new challenges for managers charged with maintaining the viability of cougar populations and their ungulate prey. Information on how cougars respond to...

Detecting minimum energy states and multi-stability in nonlocal advection–diffusion models for interacting species
Download2022-06-13
Valeria Giunta, Thomas Hillen, Mark A. Lewis, Jonathan R. Potts
Deriving emergent patterns from models of biological processes is a core concern of mathematical biology. In the context of partial differential equations, these emergent patterns sometimes appear as local minimisers of a corresponding energy functional. Here we give methods for determining the...

Diverting Resources to Turn on Resistance: Influences of Biotic and Abiotic Stresses on Aspen Seedlings
DownloadFall 2012
The interactions between biotic and abiotic stresses and their influence on plant reserves in non-photosynthetic tissues (i.e., roots and stems) and the role of plant reserves in tree defenses are poorly understood. Aspen seedlings grown under different conditions (light, fertilizer) were grouped...

Aspen is a widespread forest tree of high economic and ecological importance in western Canada. The species has also been subject to tree improvement efforts over the past two decades to increase productivity of the forested land base. Successful selection and breeding programs rely on both...

Spring 2015
Personality has been documented in diverse taxa and growing attention is being directed towards the ecological implications of consistent variation in individual behaviour. These implications include the rise in habituation behaviour by wildlife living in human-disturbed areas, which has resulted...
