Compendium of Research in the Northwest Territories 2014
Compendium of Research in the Northwest Territories 2014 www.nwtresearch.com This publication is a collaboration between the Aurora Research Institute, the Department of Environment and Natural Resources, Fisheries and Oceans Canada and the Prince of Wales Northern Heritage Centre. Thank you to all who submitted a summary of research or photographs, and helped make this publication possible. Editor: Ashley Mercer Copyright © 2015 ISSN: 1205-3910 Printed by Aurora Research Institute Foreword Welcome to the 2014 Compendium of Research in the Northwest Territories. This year marked a special anniversary for the Aurora Research Institute and northern research. Fifty years ago, the Inuvik Research Laboratory was built and has served as a hub for research in the western arctic ever since. The Lab, as it was known, was first built as an initiative of the Canadian federal government in the newly established community of Inuvik. It remains on the same site today, but in 2011, a new modern multi-purpose facility opened to continue to support research in the north. We have included a brief history of the Lab and its impact in this edition of the Compendium to mark its long lasting importance to many researchers and community members. As part of the 50th anniversary celebration, the Aurora Research Institute team undertook a full set of NWT-wide celebrations. We celebrated the history, capacity and growth of research in the NWT that touched all corners of the territory and beyond. We honoured the significant scientific contributions that have taken place in the NWT over the past 50 years, and the role of NWT researchers, technicians and citizens in these accomplishments. -

Appendix A. Survival Strategies of the Ecotonal Species
Appendix A. Survival Strategies of the Ecotonal Species With greater numbers of species found in relatively high abundance in communities of both the boreal zone and the arctic regions, with fewer in the forest-tundra ecotonal communities, the question arises as to the strategies involved that permit adaptations to disparate environments yet prohibit all but a few from surviving in the ecotone, at least in numbers sufficient so they are recorded in quadrats of the size employed in transects of this study. There is a depauperate zone in the forest-tundra ecotone marked by a paucity of species, a zone in which only a relatively few wide-ranging species are persistently dominant (see Tables 5.1-5.9). Plant communities in both the forests to the south and the tundra to the north possess more species of sufficient abundance to show up in the transects. In the depauperate zone, there is no lack of vegetational cover over the landscape, but fewer species in total dominate the communities. There are fewer species demonstrating intermediate abundance, fewer rare species. The obvious question is, "Why should this be so?" As yet, there is perhaps no fully satisfactory answer, but there have been studies that at least seem to point the way for an approach to the question. Studies of the survival and reproductive strategies oftundra plants, arctic and alpine, have a long history, and these are thoroughly discussed in classic papers and reviews by Britton (1957), Jeffree (1960), Warren Wilson (1957a,b, 1966a,b, 1967), Johnson et al. (1966), Johnson and Packer (1967), Billings and Mooney (1968), Bliss (1956, 1958, 1962, 1971), Billings (1974), and Wiclgolaski et al. -
Mapping Known and Potential Karst Areas in the Northwest Territories, Canada
Mapping Known and Potential Karst Areas in the Northwest Territories, Canada Derek Ford, PGeo., PhD, FRSC. Emeritus Professor of Geography and Earth Sciences, McMaster University [email protected] For: Environment and Natural Resources, Government of the Northwest Territories August 2009 (i) Executive Summary The Goal of this Report is to Produce Maps of the Known and Potential Karst Landform Sites in the Northwest Territories (NWT) Karst landforms are those created by the dissolution of comparatively soluble rocks and the routing of the water (from rain or snowmelt) underground via caves rather than at the surface in river channels. The principal karst rocks are salt (so soluble that it is scarcely seen at the surface in the NWT), gypsum and anhydrite (solubility around 2500 mg/l of water), and limestone and dolomite (solubility around 250 -350 mg/l). All of these rock types are common and widespread amongst the sedimentary strata in the NWT. Surface karst landforms include: a) karren, which are spreads of individually small solution pits, shafts, and runnels that, collectively, may cover many hectares (limestone pavements); b) sinkholes of solutional, collapse, or other origin that can be tens to hundreds of metres in diameter and proportionally as deep. Sinkholes are considered the diagnostic karst landform worldwide; c) larger topographically closed depressions that may flood or drain seasonally, poljes if flat-floored, otherwise turloughs; d) extensive dry valleys and gorges, dry because their formative waters have been captured underground. All water sinking underground via karst landforms of all sizes drain quickly in comparison with all other types of groundwater because they are able to flow through solutionally enlarged conduits, termed caves where they are of enterable size. -
Ancient Knowledge of Ancient Sites: Tracing Dene Identity from the Late Pleistocene and Holocene Christopher C
11 Ancient Knowledge of Ancient Sites: Tracing Dene Identity from the Late Pleistocene and Holocene Christopher C. Hanks The oral traditions of the Dene of the Mackenzie Valley contain some intriguing clues to cul tural identity associated with natural events that appear to have occurred at the end of the Pleisto cene and during the early Holocene. The Yamoria cycle describes beaver ponds that filled the ancient basins of postglacial lakes, while other narratives appear to describe the White River ash fall of 1250 B.P. This paper examines Dene views of the past and begins the task of relating them to the archaeological and geomorphological literature in an attempt to understand the cultural per spectives contained in these two different views of “history.” STORIES, NOT STONE TOOLS, UNITE US The Chipewyan, Sahtu Dene, Slavey, Hare, Mountain Dene, Dogrib, and Gwich’in are the Athapaskan-speaking people of the Northwest Territories. Collectively they refer to themselves as the Dene. Their shared cultural identity spans four distinct languages and four major dialects, and is spread from Hudson's Bay to the northern Yukon. Based on archaeological culture histories, there are relatively few strands of evidence that suggest a close relationship between these groups (Clark 1991; Hanks 1994). However, by using oral traditions, the archaeological record, linguistic theories, and the geological record, it can be argued that in the distant past the ancestors of the Dene lived as one group in the mountains along the Yukon-Alaskan border (Abel 1993: 9). For some archaeologists, the Athapaskan arrival east of the Cordilleran is implied by the appearance of a microlithic technology 6000-5000 B.P. -

This document represents the culmination of 15 years of land use planning with the purpose of protecting and promoting the existing and future well-being of the residents and communities of the Sahtu Settlement Area, having regard for the interests of all Canadians. From its beginnings in 1998, the Board’s early years focused on research, mapping, and public consultations to develop the goals and vision that are the foundation of the plan. From this a succession of 3 Draft Plans were written. Each Plan was submitted to a rigorous review process and refined through public meetings and written comments. This open and inclusive process was based on a balanced approach that considered how land use impacts the economic, cultural, social, and environmental values of the Sahtu Settlement Area. The current board would like to acknowledge the contributions of former board members and staff that helped us arrive at this significant milestone. Also, we would like to extend our gratitude to the numerous individuals and organizations who offered their time, energy, ideas, opinions, and suggestions that shaped the final Sahtu Land Use Plan. -

The overall goal ofthe AES is to preserve and enhance the integrity, health, biodiversity and productivity ofour Arctic ecosystems for the benefit ofpresent and future generations. Four specific programs address some ofthe key environmental challenges: they are waste cleanup, contaminants, water management, and environment and economy integration. The programs are managed by the Northern Affairs Program ofthe Department of Indian Affairs and Northern Development (DIAND); however, there is a strong emphasis on partnerships with northern stakeholders including Native organizations, other federal departments and the territorial governments. The AES Action on Water Program specifically strives to enhance the protection ofnorthern freshwaters through improved knowledge and decision-making. Water Resources managers in the Yukon and the Northwest Territories administer this Program which focuses on freshwater aquatic ecosystems. This report is the first detailed compilation ofstudies.conducted under the AES Action on Water Program. It covers work done from 1991 to 1994. Many studies have been concluded, while others are ongoing. Although data may not be available for all studies, or results are preliminary at this time, this report presents detailed background, objectives and methodology. -
