Ecological niche modelling : salix in Ontario
It has long been recognized that organisms exist in environments peculiar to taxa. Climate is thought to be of primary importance in determining the natural geographic distribution of species. Growing concern over climate ...
Bottom-up and top-down forces shaping caribou forage availability on the Lake Superior coast
Woodland caribou (Rangifer tarandus) occupying the Lake Superior Coastal distribution, Ontario, exist in three subpopulations with distinct ranges and demographics. In this study, three ranges are analyzed in terms of ...
Physiological and morphological responses of mountain maple (acer spicatum l.) seedlings to light under different carbon dioxide concentrations, soil temperature and soil moisture regimes
Determining the response of mountain maple (Acer spicatum L.) to increases in light is confounded by interaction with other environmental factors. Rising atmospheric carbon dioxide concentrations ([CO2]) and the accompanying ...
Characteristics of connectivity between harvested landscapes and fixed-width riparian buffers
Fixed-width riparian buffers are a common best management policy enforced in forested landscapes on first and higher order streams. These buffer areas are delineated along stream banks in the field, based on the presence ...
The distribution and role of downed woody debris in nutrient retention and cycling during early stand establishment
Coarse woody debris (CWD) in boreal ecosystems has been hypothesized to play an important nutritional role following stand-replacing disturbances such as fire or harvest. Sites with shallow soil over bedrock or those with ...
An assessment of juvenile lake sturgeon movement and habitat use in the Namakan River of Northwestern Ontario
The Namakan River of Northwestern Ontario is home to a recovering population of lake sturgeon (Acipenser fulvescens). Although the adult portion of this population has been well studied in recent years, very little information ...
