Structure and Carbon Dynamics of Boreal Forests in Discontinuous and Continuous Permafrost Zones
Principal Investigator: Osawa, Akira
Licensed Year(s): 2019 2018 2016 2015 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The possibility of climate warming demands detailed analysis of the carbon budget in boreal forest ecosystems as they may be major carbon sinks. The data from previous years suggest that forests may be losing carbon to the atmosphere. Due to large annual variation in carbon accumulation, measurements covering several years are necessary. Soil and air temperature, and soil moisture will be meas...

Carbon dynamics in chronosequence of boreal forest ecosystems: a production ecological approach
Principal Investigator: Osawa, Akira
Licensed Year(s): 2017 2005 2004 2003 2002 2001
Summary: Northern forests are closely connected to the issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The main objectives of the 2005 field season are to collect data on the annual growth of fine roots, and to further examine the rate of soil respiration. Both of these...

An Exploratory Evaluation of the Effect of the Climate Change During the Past Two Centuries on Structure of Jack Pine Forests.
Principal Investigator: Osawa, Akira
Licensed Year(s): 1999
Summary: The main objective of the proposed research is to reconstruct the structure of monospecific forests of different ages, and to explore whether or not the recent climate change has affected the structure of the forests in northern Canada. Pure stands of Jack pine or aspen will be studied in Wood Buffalo National Park. The intent is to determine the effect of the so-called Climate Change on those f...

Reconstruction of Forest Structure and function in Canadian Taiga
Principal Investigator: Osawa, Akira
Licensed Year(s): 1998 1997
Summary: The research team will consist of forest ecologists. We plan to study a few jack pine stands by taking stem samples for examination of forest growth that occurred in the past. A possible effect of climate change on the growth of forests are being examined. Several trees were cut and were analyzed last year. This summer several additional stems will be sampled. When a tree is cut, we try not to dis...
