Morgantini, L.E., Hudson, R.J.

This study was designed to provide a better understanding of the nutritional significance of wapiti (Cervus elaphus) migrations from low-elevation winter ranges onto high-elevation alpine summer ranges. The study focused on a population along the east slopes of the Rocky Mountains in western...

Models represent our primary method for integration of small-scale, process-level phenomena into a comprehensive description of forest-stand or ecosystem function. They also represent a key method for testing hypotheses about the response of forest ecosystems to multiple changing environmental...

We present an analytical model for determination of the economically optimal harvest age of a forest stand considering timber value, and the value of carbon fluxes in living biomass, dead organic matter, and wood products pools. Through comparative statics analysis, we find that consideration of...

Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In...

Abstract: The classical environmental control model assumes that species distribution is determined by the spatial variation of underlying habitat conditions. This niche-based model has recently been challenged by the neutral theory of biodiversity which assumes that ecological drift is a key...

We develop and test new models that unify the mathematical relationships among the abundance of a species, the spatial dispersion of the species, the number of patches occupied by the species, the edge length of the occupied patches, and the scale on which the distribution of species is mapped....
