Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
chercheur principal:
Année(s) de permis: 2019 2018 2016 2015 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: Main objective of the field work is to collect data in jack pine and black spruce forests on annual movement of organic matter and carbon. Additional objective is to conduct a regional study of stand development and its relationship to environmental factors in a several-square-kilometer study area of mostly black spruce. Five methods will be used. 1) Soil and air temperature will be measured...

Jack Pine Forest Research
chercheur principal:
Année(s) de permis: 1994
Résumé: The researcher will conduct research on jack pine forests along the highways in Wood Buffalo National Park and will also collect stem increment cores from black spruce trees around the latitudinal tree line near Inuvik. This research will consist of remeasurement of permanent plots, foliage distribution and light measurement, establishment of pruning experiment and stem core sampling near Inuvik....

A Northern Forest Ecosystem Simulation Model of Early Post-Fire Tree Seedling Establishment, Growth and Competition
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: The researcher and her team will glean physiological rates and relationships for tree growth from the literature and substitute the data into a functional model, which will be calibrated against intensive sampling within WBNP over dry, mesic and wet landscapes....

Testing the Allometric Theory of the Self-Thinning Rule
chercheur principal:
Année(s) de permis: 1992 1991 1987
Résumé: The researcher and his team will estimate the number of trees and monitor individual growth in flagged and tagged stands, as well as estimating foliage weight of individual trees. They will measure light conditions in various jack pine stands, as well as collect stem cores to be analyzed and compared with stem cores from other parts of the northern hemisphere for the possibility of accelerated gr...

The Ecological Genetics of Seedling Drought Resistance in Jack Pine
chercheur principal:
Année(s) de permis: 1989
Résumé: Dr. Wein and his assistant will plant jack pine seedlings in the Reid Lake and Sandy Lake area where the dry conditions simulate a drought. They hope to find a species of jack pine which will survive drought conditions in more southern forests....
