Résumé:
The objective of this project is to examine the environmental thresholds to the successful establishment of a boreal (high latitude) conifer forest by measuring photosynthetic rates in conifer seedlings. Climate change has the potential to shift southern commercial tree species and treelines northward with implications for existing ecosystems and future economic development.
The project’s goal ...

2006 Résumé:
The primary objective of the fieldwork is to collect small samples of seed from grass species in six primary Genera: Festuca, Poa, Deschampsis, Leymus, Elymus and Alopecurus. Other species may be collected. Wild mustard species (Crucifer species) will also be collected. The collections will be compared visually and genetically to other collections of the same or closely related species from Alaska...

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...

2005 Résumé:
In the fall of 2004, the West Side Working Group decided to develop a program to monitor the Big Fish River, involving students from the high school, Hunters and Trappers Committee (HTC) members, and elders. This project will include a week-long field trip each year to the Big Fish River, as well as classroom learning, and reporting back to community members. The project will monitor changes in ...

Résumé:
Indigenous rare plants exist in the NWT, including in parts of the Mackenzie Mountains and the Beaufort Sea coast (especially in areas that were not glaciated). Alien species may be spreading along roads. There are 94 species of alien plants, transported to the territories by human activity.
Surveys pf alien and rare plants will be conducted along roads in the North, South Slave and DehCho reg...

Résumé:
The goal of this study is to gather information about fish and fish habitat to minimize and monitor impacts associated with the proposed Mackenzie Gas Pipeline. Broad whitefish, inconnu, arctic cisco and lake whitefish are the major fish species taken in subsistence fisheries in the Mackenzie Valley. These species are highly migratory and are targeted by multiple fisheries along their migration ro...

2003 Résumé:
Government agencies responsible for grizzly bear management have made significant investments in biological studies; however, wildlife management programs based solely on biology, without understanding the human side of grizzly bear management, run the risk of creating conflicts. People who share the land with bears are especially affected by these decisions. These conflicts can waste time and mon...

Résumé:
The northern subspecies of Dolly Varden char is represented by only five populations in Canada. Of these populations, the Vittrekwa River Dolly Varden has been least studied. In the late 1990s, the presence of this fish was confirmed by the Gwich’in Renewable Resource Board and the Department of Fisheries and Oceans. Data collected through studies conducted by these organizations showed that at le...

Résumé:
Currently, little information exists on the fisheries resources of the Arctic Red River. Baseline information on fisheries resources is required to make sound management decisions. This information (e.g., biological characteristics of fish: length, weight, age at maturity, migration patterns, date of spawning; presence/absence of species) is collected through long-term studies, traditional knowled...
