Global increases in carbon dioxide have refocused attention on trees as a mechanism for carbon storage. Leaves are vital to this process, serving as both the site of carbon gain and water loss in trees. As transpiration and photosynthesis are inherently linked in leaves, water movement through...

There is evidence of warming and changes in precipitation over recent decades in most regions of North America (NA) that are affecting ecosystem productivity. The impacts of these changes on land-atmosphere carbon exchange over a wide range of biomes are spatially heterogeneous and uncertain. In...

Species worldwide are becoming increasingly threatened due to the rapid changes in climate and land use induced by human activities. The loss of species threatens the provision of food, goods and many other ecosystem services essential to the sustainability and well-being of human society. It is...

A long term project being conducted on a population of Peregrine Falcons (Falco peregrinus) breeding near Rankin Inlet, Nunavut, Canada, has chronicled a steady decline in annual productivity over 30 years. By documenting the direct effects of summer rainfall on nestling mortality, a recent study...

Lightning is widely acknowledged as a major cause of wildland fires in Canada. On average, 250,000 cloud-to-ground lightning strikes occur in Alberta every year. Lightning-caused wildland fires in remote areas have considerably larger suppression costs and a much greater chance of escaping...

We examined a direct forest floor transfer reclamation technique to establish a native boreal forest understory plant community on a reclamation site at a coal mine. Forest floor material was salvaged from an aspen-dominated (Populus tremuloides Michx.) donor forest at two depths (15 and 40 cm)...
