Exploring Picea glauca aquaporins in the context of needle water uptake and xylem refilling
Download2014
Conifer needles have been reported to absorb water under certain conditions. Radial water movement across needle tissues is likely influenced by aquaporin (AQP) water channels. Foliar water uptake and AQP localization in Picea glauca needles were studied using physiological and microscopic...

Factors influencing size inequality in peatland black spruce and tamarack: Evidence from post-drainage release growth
Download1999
1 We used tree ring analysis to determine stem radius and thus examine size variation over time in two even-aged (approximately 40-year-old) mixed populations of black spruce and tamarack established on peatlands in a boreal forest. We also followed the response of one of these populations to...

Abstract: Fire has been the dominant disturbance in boreal America since the Pleistocene, resulting in a spatial mosaic in which the most fire occurs in the continental northwest. Spatial variation in snowshoe hare ( Lepus americanus) density reflects the fire mosaic. Because fire initiates...

Fire regimes at the transition between mixedwood and coniferous boreal forest in northwestern Quebec.
Download2004
Flannigan, M., Kafka, V., Gauthier, S., Bergeron, Y.
Fire history was reconstructed for an area of 15 000 km2 located in the transition zone between the mixed and coniferous forests in Quebec's southern boreal forest. We used aerial photographs, archives, and dendroecological data (315 sites) to reconstruct a stand initiation map for the area. The...

Boreal wetlands play an important role in global carbon balance. However, their ecosystem function is threatened by direct anthropogenic disturbance and climate change. Oil sands surface mining in the boreal regions of Western Canada denudes tracts of land of organic materials, leaves large areas...
