The network was divided into five regional groups based on geography, tree species, and length of record: the eastern Rockies, northern Saskatchewan, central Manitoba, southern Manitoba, and northwestern Ontario. Regional tree-ring records are primarily related to summer moisture and drought conditions, and are less responsive to droughts caused by deficits in winter precipitation. These summer-sensitive data are not linearly related to major modes of climate variability, including ENSO and the Pacific decadal oscillation (PDO), which primarily affect the climate of western Canada during winter. Extended drought records inferred from tree rings indicate that drought on the Canadian Prairies has exhibited considerable spatial heterogeneity over the last several centuries. For northern Saskatchewan and northwestern Ontario, intervals of persistently low tree growth during the twentieth century were just as long as or longer than low-growth intervals in the eighteenth or nineteenth centuries. Longer records from southern Alberta suggest that the most intense dry spell in that area during the last 500 yr occurred during the 1720s. At the eastern side of the prairies, the longest dry event is centered around 1700 and may coincide with low lake stands in Manitoba, Minnesota, and North Dakota. Although the Canadian Prairies were dry at times during the 1500s, there is no regional analog to the sixteenth-century ‘‘megadroughts’’ that affected much of the western United States and northern Mexico. 1.

Dr. Tony Russell Associate Professor Ph.D. Chair, Thesis Examination Committee ABSTRACT Modern studies in phylogeography integrate many once-disparate scientific fields. This study investigated terrestrial mountain snails, Oreohelix spp., in southern Alberta using DNA markers and the recent emergence of the trematode parasite Dicrocoelium dendriticum. Large-bodied snails in Cypress Hills (CH) and the Rocky Mountains (RM) formed three clades within the species complex O. subrudis. One was geographically widespread, one was restricted to one region in the RM, and one was restricted to CH. Small-bodied snails in CH were determined to be O. cooperi, a rare Oreohelid thought to be imperilled in the western U.S.A. Phylogeographic analyses determined that snails likely colonized and came into contact in CH due to its glacial history.

  • The Thermal State of Permafrost in Canada – Results from the International Polar Year
    The Thermal State of Permafrost in Canada – Results from the International Polar Year Sharon L. Smith 1, Antoni G. Lewkowicz 2, Christopher R. Burn 3, Michel Allard 4 & Jennifer Throop 2 1Geological Survey of Canada, Natural Resources Canada, Ottawa, Ontario, Canada 2Department of Geography, University of Ottawa, Ottawa, Ontario, Canada 3Department of Geography and Environmental Studies, Carleton University, Ottawa, Ontario, Canada 4Centre d’études nordiques, Université Laval, Ste-Foy, Québec, Canada ABSTRACT A snapshot of permafrost thermal state in northern Canada during the International Polar Year was developed with ground temperature measurements from about 170 boreholes. The measurements span a wide range of ecoclimate and geological conditions and are at various elevations. Ground temperatures within the discontinuous permafrost zone are generally above -2°C and range to as low as -15°C in the continuous zone. Permafrost temperatures have generally increased across northern Canada for the past several decades, with greater warming rates occurring north of tree line. Consequently the spatial diversity of permafrost thermal conditions is decreasing over time. RÉSUMÉ Un instantané de l’état thermique du pergélisol dans le nord du Canada au cours de l’Année polaire internationale a été élaboré en utilisant les mesures des températures au sol obtenues d’environ 170 puits. Les mesures couvraient une vaste gamme de conditions écoclimatiques et géologiques et diverses élévations. Les températures au sol au sein de la zone discontinue de pergélisol étaient généralement supérieures à -2°C et descendaient jusqu’à -15°C dans la zone continue. Les températures du pergélisol ont généralement augmenté dans tout le nord du Canada au cours des dernières décennies, les taux de réchauffement les plus marqués étant survenus au nord de la ligne des arbres.

  • I. 1. the Influence of Permafrost on Northern Development
    I. 1. THE INFLUENCE OF PERMAFROST ON NORTHERN DEVELOPMENT INTRODUCTION The expansion of settlement from man's early home in the fertile, friendly and protected river valleys of the Middle East has been marked by conquest of one natural obstacle after another. Broad seas, hot, dry deserts, mountain ranges and dense forests each in their turn arrested his progress until new techniques were devised and perfected, and became common knowledge. His invasion of the tropical rainforests was delayed by diseases, and his ventures into the far north - what Stefansson has termed "The .Northward Course of Empire" (1) - were handicapped by severe cold and snow, and by the heavy ice which impeded and damaged his ships. In his long and frequently frustrated efforts to make a home in even the remotest parts of the earth, man has encountered, and eventually learned to deal with, an enormous variety of natural hazards. Perennially frozen ground in the polar regions is one of his most recent natural obstacles. It has become of major importance only in the past few decades, although its existence has long been known. Alexander Mackenzie mentioned it and Jules Verne wrote a novel (2) based in part on it, while the quick-frozen mammoths of Siberia have been a cause of wonder for generations. How was it that such a widespread phenomenon, covering about one-half of Canada and almost as great a proportion of the Soviet Union, should nevertheless have attracted so little attention that until a few years ago it even lacked a commonly accepted English name and is only now being honoured in Canada by a national symposium ? The world population map demonstrates that man has as yet barely reached in any numbers the southern limit of that one-fifth of the land surface underlain by permafrost.

A Socio-Economic Evaluation of Sportsfishing Activity in Southern Alberta Interim Project Report INTROI)UCTION Recreational fishing is one of the most important recreational activities in Alberta. The report on Sports Fishing in Alberta, 1985, states that over 340,000 angling licences were purchased in the province and the total population of anglers exceeded 430,000. Approximately 5.4 million angler days were spent in Alberta and over $130 million was spent on fishing related activities. Clearly, sportsfishing is an important recreational activity and the fishery resource is the source of significant social benefits. A National Angler Survey is conducted every five years. However, the results of this survey are broad and aggregate in nature insofar that they do not address issues about specific sites. It is the purpose of this study to examine in detail the characteristics of anglers, and angling site choices, in the Southern region of Alberta. Fish and Wildlife agencies have collected considerable amounts of bio-physical information on fish habitat, water quality, biology and ecology.

  • The Mounties and the Origins of Peace in the Canadian Prairies∗
    The Mounties and the Origins of Peace in the Canadian Prairies∗ Pascual Restrepo October 2015 Abstract Through a study of the settlement of the Canadian Prairies, I examine if differences in violence across regions reflect the historical ability of the state to centralize authority and monopolize violence. I compare settlements that in the late 1880s were located near Mountie- created forts with those that were not. Data from the 1911 Census reveal that settlements far from the Mounties’ reach had unusually high adult male death rates. Even a century later the violence in these communities continues. In 2014, communities located at least 100 kilometers from former Mountie forts during their settlement had 45% more homicides and 55% more violent crimes per capita than communities located closer to former forts. I argue that these differences may be explained by a violent culture of honor that emerged as an adaptation to the lack of a central authority during the settlement but persisted over time. In line with this interpretation, I find that those who live in once-lawless areas are more likely to hold conservative political views. In addition, I use data for hockey players to uncover the influence of culture on individual behavior. Though players interact in a common environment, those who were born in areas historically outside the reach of the Mounties are penalized for their violent behavior more often than those who were not.

    water Article Hydrological Extremes in the Canadian Prairies in the Last Decade due to the ENSO Teleconnection—A Comparative Case Study Using WRF Soumik Basu * , David J. Sauchyn and Muhammad Rehan Anis Prairie Adaptation Research Collaborative, Regina, SK S4S 0A2, Canada; [email protected] (D.J.S.); [email protected] (M.R.A.) * Correspondence: [email protected] Received: 8 September 2020; Accepted: 21 October 2020; Published: 23 October 2020 Abstract: In the Prairie provinces of Alberta, Saskatchewan, and Manitoba, agricultural production depends on winter and spring precipitation. There is large interannual variability related to the teleconnection between the regional hydroclimate and El Niño and La Niña in the Tropical Pacific. A modeling experiment was conducted to simulate climatic and hydrological parameters in the Canadian Prairie region during strong El Niño and La Niña events of the last decade in 2015–2016 and 2010–2011, respectively. The National Center for Atmospheric Research (NCAR) Weather Research and Forecasting (WRF) model was employed to perform two sets of sensitivity experiments with a nested domain at 10 km resolution using the European Centre for Medium-Range Weather Forecasts Reanalysis (ERA) interim data as the lateral boundary forcing. Analysis of the hourly model output provides a detailed simulation of the drier winter, with less soil moisture in the following spring, during the 2015–2016 El Niño and a wet winter during the La Niña of 2010–2011. The high-resolution WRF simulation of these recent weather events agrees well with observations from weather stations and water gauges. Therefore, we were able to take advantage of the WRF model to simulate recent weather with high spatial and temporal resolution and thus study the changes in hydrometeorological parameters across the Prairie during the two extreme hydrological events of the last decade.

  • Casting in the Dark, on Alberta's Crowsnest River
    Lundbreck Falls Casting in the dark, on Alberta’s Crowsnest River. By Dana Sturn Curtis Hall A friend lost a fly box on the Crowsnest River. It slipped out of an open vest pocket. We never knew where or when. All we knew was it was gone. I searched down one side while Richard splashed across and searched down the other until his progress was halted where the river rushed up against a rock wall. He waived me off, and pointed upstream, signaling I should meet him back where we started. “This sucks,” he said, wading out. “All my Stealth Caddises were in there.” His first trip to Alberta wasn’t off to the best start. Crap weather and reluctant rainbows made his few days on the Bow near Calgary underwhelming, so this morning on the two-hour drive south I assured him that the Crowsnest would be different. But now I imagined the box—my gift of a clear Orvis full of perfect little hand ties— spinning in eddies and bumping off boulders, eventually tumbling over Lundbreck Falls a few kilometers downstream. There are some big trout below those falls. At dusk they start looking up for caddisflies that the size-16 Stealth Caddis matches perfectly in dark waters. Now he didn’t have any. And that’s where we were headed. Smaller and wilder than the Bow, the Crowsnest flows east along Highway 3 in southwestern Alberta, until it joins the Oldman River northeast of the village of Cowley. It’s a walk and wade dream river that fishes best late June through early autumn.
