Summary: The objective of this sub-project are: 1) to continue assessing the performance of native plants which were seeded and transplanted into field plots in 2006 and 2007; and, 2) to establish two new field plots at the Inuvik golf course with the same intent of monitoring native seed performance in a disturbed habitat. The research team intend to collect data regarding winter survival, seedling e...

Summary: The objective of this research is to assess variations and processes controlling CO2, CH4 and N2O dynamics along the Mackenzie Valley, to investigate the amount and character of greenhouse gases released, and to understand conditions controlling soil GHG emissions. Soil gas sample tubes will be sampled on a seasonal basis for gas concentration (CH4, N2O, CO2) and isotope ratios. The response of...

Summary: Specific activities for this field season include the following: (1) Resolution of the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta (year 3 of PhD thesis project of S. Tank). This information is needed to ultimately understand the relative role of bacterial (fueled by DOC) versus photosynthetic organisms and their importance in ultimately sup...

Summary: The objective of this research is to explore the influence of temperature and disturbance on green alder by comparing alder characteristics on sites with different average temperatures and disturbance histories. Understanding of factors that influence alder populations today will assist in predicting the likely consequences of rising temperatures and increased disturbance on tall shrubs. A min...

Summary: The researchers will measure black spruce forests along the Dempster Highway. They will determine if the trees can only grow to a certain limit that cannot be surpassed, regardless of the number of trees per hectare. A limit of this kind was recently discovered in Siberia. The number of trees per hectare and above-ground biomass will be estimated in numerous black spruce stands. A method ...

Summary: The 2005 terrestrial studies include vegetation mapping, rare plant surveys, rare plant mitigation planning, timber cruising, and landform, soil and permafrost investigations. All of the studies will be conducted by three- or four-person crews supported by helicopter. A local assistant will be included as part of each terrestrial survey team to assist in observing and recording data taken at surve...

Summary: The purpose of this project is to identify the factors that promote or retard forest regrowth after seismic line cutting. Little was known about tree regeneration on seismic lines until the 2001-2003 study by Seccombe-Hett and Walker-Larsen, which showed that older lines were well-stocked but that the delay in coloniziation might be caused by dramatic subsidence and resulting water-logging. ...

Principal Investigator: Pettit, George Robert
Licensed Year(s): 1999 1995
Summary: The researcher will collect by hand, usually along the roadside, approximately several grams of soil and mud specimens to be returned to the Cancer Research Institute laboratories for evaluation for microorganism constituents which may have potential anticancer activity....

Principal Investigator: Durham, J. Wyatt
Licensed Year(s): 1995 1990
Summary: The researchers will collect specimens of fossil molluscs exposed in critical areas. This involves simply breaking rocks loose from their location. No excavation deeper than 1 foot is contemplated. Localities will be marked on topographic maps and measurements of sections exposed in river banks will be made. Analysis will be completed in California. Significant specimens will be returned to t...

Principal Investigator: Broll, Gabriele
Licensed Year(s): 1993
Summary: As part of his trip to Inuvik with the International Tour of Permafrost Affected Soils, the researcher will record information about the ecology (including local climate conditions, soil conditions and plant communities) of the timberline at selected sites visited during the Tour. These sites are located along the Dempster Highway near Inuvik....
