  • The Political Ecology of the George River Caribou Herd
    Science, Conservation, and Indigenous Rights: The Political Ecology of the George River Caribou Herd by Romea Dennis supervised by Gregory Thiemann A Major Paper submitted to the Faculty of Environmental Studies in partial fulfillment of the requirements for the degree of Master in Environmental Studies York University, Toronto, Ontario, Canada 2018/07/31 Dennis 2 Dennis 3 (International, n.d.) Dennis 4 Foreword Climate change is altering the physical world and triggering biophysical impacts that modify our environments and our society. An example of this is caribou decline in northern Canada. The George River caribou herd decreased from upwards of 800,000 animals in the 1990s and approximately 8,900 animals in 2016. The herd’s decline is a manifestation of industrial development, resource management, wildlife conservation, indigenous land use and government environmental policy interactions. My plan of study focused on climate change science, perspectives and policy as well as political ecology. Political ecology links human causes and environmental reactions. Researching the various human and environmental causes that led to the 99% decline of the George River caribou herd allowed me to research components of my plan of study in action. Science, Conservation, and Indigenous Rights: The Political Ecology of the George River Caribou Herd explores scientific, indigenous and government perspectives of what caused the drastic decline of the George River caribou herd. The case of the herd fits in the zeitgeist of 2018 Canadian environmental issues- the melting Arctic, governments scrambling to balance economic interests with environmental conservation and indigenous users being both marginalized and empowered in resource management issues.

(NTI) is holding information sessions about current Inuit issues for the local and international media during the G7 meetings on Feb. 4 and 5, 2010. The sessions will be held in the NTI Iqaluit boardroom located on the third floor of the Igluvut Building (Royal Bank Building). For more information, please contact NTI Director of Communications Franco Buscemi by email [email protected] or call 867-975-4939. NTI is the organization that represents Inuit under the NLCA. NTI’s mission is to foster Inuit economic, social and cultural well-being through the implementation of the NLCA. NTI implements Inuit obligations in the NLCA, and ensures that other parties to the NLCA meet their obligations. 1. The State of Inuit Culture and Society Feb. 4, 1:30-2:30 p.m. Natan Obed Virginia Lloyd This session will focus on the current social realities of Inuit in Nunavut, especially in relation to the general Canadian population. In addition to a general introduction to Inuit culture, information will be provided on educational outcomes, life expectancy, health conditions, housing, social indicators, and language. Trends will be shown and the challenges outlined that must be addressed. 2.

  • Fire History at the Treeline in Northern Quebec: a Paleoclimatic Tool 1 Serge Payette2
    This file was created by scanning the printed publication. Errors identified by the software have been corrected; however, some errors may remain. Fire History at the Treeline in Northern Quebec: A Paleoclimatic Tool 1 Serge Payette2 Abstract.--The long term fire history at the treeline in Northern Quebec can be evaluated by ecological surveys of the major ecosystems. Available data suggest that fires are presently climate-controlled, and therefore may be used as paleoclimatic indicators. During a cold climatic interval, postfire tree regeneration is hindered, and a shift from forest to barren conditions is recorded. Examples from specific environments are provided in order to reconstruct significant ecological periods of the fire history since 3,000 years B.P. (Before Present). A pre­ liminary interpretation indicates that these periods of climatic cooling are centered around 2,800-2,500, 2,200- 2,000, 1,600-1,400, 1,100-900, 700 ? , 500-100 years B.P. and Present.

  • Breeding Bird Surveys at Alexandra Fiord, Ellesmere Island, Nunavut (1980–2008) Sarah A
    ARCTIC VOL. 63, NO. 3 (SEPTEMBER 2010) P. 308–314 Breeding Bird Surveys at Alexandra Fiord, Ellesmere Island, Nunavut (1980–2008) SARAH A. TRefRY,1,2 BILL FREEDMan,3 JAMes M.G. HUDSON1 and GRegORY H.R. HenRY1 (Received 13 July 2009; accepted in revised form 16 December 2009) AbstRACT. Long-term monitoring of bird populations in the Arctic is of considerable interest as this area is experiencing rapid climate warming; however, multi-decadal studies in the Canadian High Arctic are rare. Over five summers between 1980 and 2008, we conducted breeding bird surveys by walking transects and mapping territories in a periglacial lowland on east-central Ellesmere Island, Nunavut. In all survey years, snow bunting (Plectrophenax nivalis), Lapland longspur (Calcarius lapponicus), and Baird’s sandpiper (Calidris bairdii) were the most abundant species. Over the study period, the assemblage of breeding bird species appears to have changed little, except for an increase in Lapland longspur. In the summer of 2008, we also compared two techniques for censusing territories. We found that spot-mapping, a simple and cost-effective method, produced similar results to the more labour-intensive active-flushing. Spot-mapping is therefore suitable for conducting bird surveys in northern locations where the vegetation is short, the terrain is flat, and the visibility is extensive. In the coming years, it will be important to continue monitoring Arctic birds to determine how climate change is affecting their breeding populations. Key words: active-flushing, Arctic, climate change, Ellesmere Island, High Arctic, monitoring, rope-drag, spot-mapping, survey RÉSUMÉ. La surveillance à long terme des populations d’oiseaux de l’Arctique revêt un intérêt considérable à la lumière du changement climatique rapide que connaît cette région.
