In this paper we present the results from a systematic literature review of subsistence research that was conducted in northern Canada between 1950 and 2019. Our analysis identified trends in subsistence research, including the breadth of research topics, influential scholars and scholarship, and the emergence of research networks. Our results identified 245 publications authored by a multidisciplinary network of 365 scholars. Research conducted through ArcticNet and the International Polar Year is responsible for 75% (n = 183 of 245) of all subsistence-related publications during this period. Subsistence publications cover a wide range of topics, including climate change, nutrition, and wildlife management, but Indigenous food culture and the roles of women in subsistence have received comparatively less scholarly attention. Given the profound changes occurring in northern Canada, whether a result of anthropogenic or non-anthropogenic disturbances, greater attention to the cultural and gendered dimensions of subsistence will be particularly valuable to northern scholarship and the public policies it can inform. This attention will be increasingly necessary in a time when critical thinking about the future of subsistence in northern Canada is of critical need.
在本文中,我们介绍了1950年至2019年间在加拿大北部进行的生存研究的系统文献综述的结果。我们的分析确定了生存研究的趋势,包括研究主题的广度、有影响力的学者和学术,以及研究网络的出现。我们的研究结果确定了由365名学者组成的多学科网络撰写的245篇出版物。在此期间,通过ArcticNet和国际极地年进行的研究占所有与生存有关的出版物的75%(n=183,共245份)。生计出版物涵盖了广泛的主题,包括气候变化、营养和野生动物管理,但土著食品文化和妇女在生计中的作用受到的学术关注相对较少。鉴于加拿大北部发生的深刻变化,无论是人为干扰还是非人为干扰,对生存的文化和性别层面的更多关注对北方学术及其所能提供的公共政策将特别有价值。在迫切需要对加拿大北部生存的未来进行批判性思考的时候,这种关注将变得越来越必要。

Burrowing species rely on subterranean and subnivean sites to fulfill important life-history and behavioral processes, including predator avoidance, thermoregulation, resting, and reproduction. For these species, burrow architecture can affect the quality and success of such processes, since characteristics like tunnel width and chamber depth influence access by predators, thermal insulation, and energy spent digging. Wolverines (Gulo gulo) living in Arctic tundra environments dig burrows in snow during winter for resting sites and reproductive dens, but there are few published descriptions of such burrows. We visited 114 resting burrows and describe associated architectural characteristics and non-snow structure. Additionally, we describe characteristics of 15 reproductive den sites that we visited during winter and summer. Although many resting burrows were solely excavated in snow, most incorporated terrain structures including cliffs, talus, river shelf ice, thermokarst caves, and stream cutbanks. Burrows typically consisted of a single tunnel leading to a single chamber, though some burrows had multiple entrances, branching tunnels, or both. Tunnels in resting burrows were shorter than those in reproductive dens, and resting chambers were typically located at the deepest part of the burrow. Reproductive dens were associated with snowdrift-forming terrain features such as streambeds, cutbanks on lake edges, thermokarst caves, and boulders. Understanding such characteristics of Arctic wolverine resting and reproductive structures is critical for assessing anthropogenic impacts as snowpack undergoes climate-driven shifts.
穴居物种依靠地下和亚地下场所来完成重要的生活史和行为过程,包括捕食者的躲避、体温调节、休息和繁殖。对于这些物种来说,洞穴结构会影响这些过程的质量和成功,因为隧道宽度和洞穴深度等特征会影响捕食者的进入、隔热和挖掘所花费的能量。生活在北极苔原环境中的狼獾(Gulo-Gulo)在冬天在雪地里挖洞作为休息场所和繁殖窝点,但很少有关于这种洞穴的公开描述。我们参观了114个休息洞穴,并描述了相关的建筑特征和非雪结构。此外,我们还描述了我们在冬季和夏季访问的15个繁殖巢穴的特征。尽管许多休息洞穴都是在雪地里挖掘的,但大多数都包含了地形结构,包括悬崖、距骨、河架冰、热溶洞和溪流路堑。洞穴通常由一条通往一个洞穴的隧道组成,尽管有些洞穴有多个入口、分支隧道或两者兼而有之。休息洞穴中的隧道比繁殖洞穴中的短,休息室通常位于洞穴的最深处。繁殖巢穴与形成雪堆的地形特征有关,如河床、湖泊边缘的河岸、热溶洞和巨石。了解北极狼獾休息和繁殖结构的这些特征,对于评估雪堆发生气候变化时的人为影响至关重要。

Since interactions and conflicts between polar bears (Ursus maritimus) and people are reportedly increasing across the Arctic, there is a pressing need to better understand how such conflicts can be prevented or their outcomes ameliorated. A great deal of knowledge about what strategies work for both preventing and mitigating human-polar bear conflicts lies with local experts, yet this knowledge has often remained relatively inaccessible to contemporary wildlife managers. This study had three main aims: to document and synthesize local knowledge of polar bear behaviour in Churchill, Manitoba, to characterize perceptions and interpretations of polar bears, and to examine the linkage between local experts’ knowledge, perceptions, and actions. We identified a suite of bear behaviours that local experts consistently observe and interpret as cues to the bears’ intent. These behaviours are not unique to this locale. Nevertheless, differences in perspectives on the predictability of polar bear behaviour and in interpretations of the nature of bears significantly influence study participants’ strategies for responding to bears. Our findings demonstrate that human-related factors are more complex than current models of human-bear interactions account for, so there is a need to develop richer models for understanding what motivates and influences human behaviours and responses towards bears. 
据报道,在整个北极地区,北极熊(Ursus maritimus)与人类之间的互动和冲突正在增加,因此迫切需要更好地了解如何预防这种冲突或改善其结果。关于预防和减轻人类与北极熊冲突的策略的大量知识都掌握在当地专家手中,然而当代野生动物管理者往往相对难以获得这些知识。这项研究有三个主要目的:记录和综合当地对马尼托巴省丘吉尔北极熊行为的了解,描述对北极熊的看法和解释,并检查当地专家的知识、看法和行动之间的联系。我们确定了一套熊的行为,当地专家一直观察并解释为熊的意图的线索。这些行为并不是这个地区独有的。然而,对北极熊行为可预测性的不同看法和对熊的性质的不同解释显著影响了研究参与者应对熊的策略。我们的研究结果表明,人类相关因素比目前的人熊互动模型更复杂,因此需要开发更丰富的模型来理解是什么激励和影响了人类对熊的行为和反应。

Few concurrent studies exist of sympatric gray wolf (Canis lupus) and coyote (C. latrans) harvest at far northern latitudes. Moreover, no studies explicitly examine effects of concurrent harvest on phenotypes of wolves and coyotes. We documented changes in sex and age characteristics and morphology of gray wolves and coyotes harvested by hunters near Ptarmigan Lake, east-central Alaska, USA, between 1998 and 2001. We hypothesized that the harvest would result in larger, heavier canids, reduce densities, and increase young to adult ratios in both wolves and coyotes. We generated von Bertalanffy growth curves indicating that wolves and coyotes of both sexes increased in length or weight until 2 or 3 years old. No significant changes in either mean length or weight or length to weight ratios occurred during the 3-year study, except that coyote mean length was longer over the last winter of study. Catch-per-unit effort (CPUE) for wolves ranged from 0.061 to 0.112 killed/day and for coyotes from 0.552 to 0.11 killed/day over the study. CPUE indicated that coyotes but not wolves declined in abundance. Changes in male to female and young to adult ratios did not differ significantly for either canid. We posit that coyote populations were disproportionately affected by the conflation of the severe Arctic environment and sustained harvest. Our findings will be beneficial for managing sympatric canid populations and for understanding demographic responses to density-dependent processes in wolves and coyotes, especially at far northern latitudes.
在远北纬地区,对同域灰狼(Canis lupus)和土狼(C. latrans)收获的研究很少。此外,没有研究明确检查同时收获对狼和土狼表型的影响。我们记录了1998年至2001年间美国阿拉斯加州中东部雷鸟湖附近猎人捕获的灰狼和土狼的性别、年龄特征和形态变化。我们假设,收获会导致更大、更重的犬科动物,降低密度,并增加狼和土狼的幼崽与成年狼的比例。我们生成了von Bertalanffy生长曲线,表明狼和土狼在2岁或3岁之前的长度或体重都在增加。在为期3年的研究中,除了土狼的平均长度在研究的最后一个冬天更长之外,平均长度或体重或长重比都没有发生显着变化。在研究中,狼的单位捕获量(CPUE)从0.061到0.112只/天不等,土狼的单位捕获量从0.552到0.11只/天不等。CPUE表明,土狼的数量减少,而狼的数量没有减少。在两种犬科动物中,雄犬对雌犬和幼犬对成年犬的比例变化没有显著差异。我们假设土狼的数量不成比例地受到了北极恶劣环境和持续收获的双重影响。我们的研究结果将有助于管理同域犬科动物种群,并有助于理解狼和土狼对密度依赖过程的人口反应,特别是在远北纬地区。

Modelling Tundra Ponds as Initiators of Peat Plateau Thaw, Northern Hudson Bay Lowland, Manitoba 将苔原池塘建模为马尼托巴省哈德逊湾北部低地泥炭高原解冻的始作俑者

Frozen peat in permafrost regions poses a potential source of increased greenhouse gas production should these deposits thaw. Ponds on frozen peat plateaus in northern Manitoba are numerically modelled as heat sources to determine their potential to promote thaw. Modelling indicates that anticipated climate warming of approximately 2 °C between 2020 and 2050 will produce taliks up to few metres thick beneath ponds a few tens of metres across. However, active-layer thickness in the subaerial parts of peat plateaus will not increase beyond the peat thickness. These findings assume 1) a climate warming rate under a moderately effective intervention in greenhouse gas production, 2) pond freezing regimes that represent both rapid ice formation and ice formation delayed by rapid snow accumulation and 3) snow thermal conductivities that anticipate snow conductivity increase during the freeze interval. These conditions and properties may turn out to be less conducive to talik expansion than the values that will actually occur. Despite these uncertainties, peat plateau pond sizes and plateau margin positions can be monitored to ascertain the onset of accelerated thawing.
如果这些沉积物融化,永久冻土区的冷冻泥炭可能会增加温室气体的产生。马尼托巴省北部冰冻泥炭高原上的池塘被数值模拟为热源,以确定其促进解冻的潜力。建模表明,预计2020年至2050年间气候变暖约2°C,将在几十米宽的池塘下产生几米厚的Talik。然而,泥炭高原陆上部分的活动层厚度不会超过泥炭厚度。这些发现假设1)在对温室气体生产进行适度有效干预的情况下,气候变暖率;2)池塘冻结状态,代表快速结冰和因快速积雪而延迟的结冰;3)雪热导率,预测冻结期间雪的热导率增加。这些条件和性质可能比实际发生的值更有利于talik膨胀。尽管存在这些不确定性,但可以监测泥炭高原池塘的大小和高原边缘位置,以确定加速解冻的开始。

Archaeological evidence indicates that Birnirk peoples (AD 650 – 1300) are the proposed genetic ancestors of the Thule Inuit (AD 950 – 1400) and are potentially an intermediary population between the Thule Inuit and earlier Old Bering Sea people (AD 1 – 1000). We sequenced the first hypervariable region of the mitochondrial DNA of 22 clearly associated Birnirk individuals from the Piġniq (Birnirk), Kugok, Kugusugaruk, and Nunavak sites on the North Slope of Alaska. Haplotypes A2a, A2a1, A2a3, A2b1, and D4b1a2a1a were identified in this population, demonstrating an expansion of Birnirk maternal genetic diversity. Maternal lineages from these individuals were evaluated with other past and contemporary Inuit populations from the Chukotka Peninsula to eastern Greenland. Our findings confirm Birnirk Inuit as probable maternal ancestors to Thule Inuit and may be among the first peoples possessing these lineages to have moved into the western North American Arctic from the Bering Strait region.
考古证据表明,Birnirk人(公元650–1300年)是图勒因纽特人(公元950–1400年)的遗传祖先,可能是图勒因纽特人和更早的古白令海人(公元1–1000年)之间的中间群体。我们对来自阿拉斯加北坡Piġniq(Birnirk)、Kugok、Kugusugaruk和Nunavak位点的22个明显相关的Birnirk个体的线粒体DNA的第一个高变区进行了测序。在该群体中鉴定出单倍型A2a、A2a1、A2a3、A2b1和D4b1a2a1a,表明Birnirk母体遗传多样性的扩大。这些个体的母系谱系与从楚科奇半岛到格陵兰岛东部的其他过去和当代因纽特人种群进行了评估。我们的研究结果证实,Birnirk因纽特人可能是Thule因纽特人的母系祖先,可能是最早从白令海峡地区进入北美北极西部的拥有这些谱系的民族之一。

Ice bridges are unique features that form when sea ice consolidates and remains immobilized within channels. They form in many locations throughout the Arctic and are typically noted for the polynyas that form on their lee side. However, ice bridges also provide a temporary platform that may be used by both humans and wildlife to cross otherwise impassable channels. For generations, Inuit in Coral Harbour, Nunavut, have used an ice bridge to cross Roes Welcome Sound and expand their hunting territory, though they report that the bridge only forms approximately every four years. Of interest both to Inuit and the scientific community is why the bridge forms so intermittently, by what mechanisms, and whether the frequency will change with ongoing warming and sea ice loss. Using satellite imagery, we determined that the bridge formed during 14 of the past 50 years (1971 – 2020). Generally, the bridge forms between January and March, during a cold period that coincides with neap tide, and after surface winds have rotated from the prevailing northerly (along-channel) winds to west-northwesterly (across-channel) winds. This rotation compresses the existing ice pack against Southampton Island, where it remains stationary because of the calm along-channel winds and low tidal range, and coalesces under cold air temperatures. Breakup occurs between mid-June and early July after the onset of melt. Overall, the bridge forms when a specific set of conditions occur simultaneously; however, a warming climate, specifically a reduction in very cold days, and shorter ice season may affect the frequency of bridge formation, thereby limiting Inuit travel.
冰桥是海冰在河道内固化并保持不动时形成的独特特征。它们在整个北极的许多地方形成,并以背风侧形成的多冰湖而闻名。然而,冰桥也提供了一个临时平台,人类和野生动物可以利用它来穿越否则无法通行的渠道。努纳武特珊瑚港的因纽特人世世代代都用一座冰桥穿过罗埃斯欢迎湾,扩大他们的狩猎范围,尽管他们报告说这座桥大约每四年才形成一次。因纽特人和科学界都感兴趣的是,为什么这座桥的形成如此间歇性,通过什么机制,以及频率是否会随着持续的变暖和海冰的减少而改变。利用卫星图像,我们确定了这座桥在过去50年(1971 - 2020年)中的14年形成。一般来说,桥在1月到3月之间形成,在一个与小潮同时发生的寒冷时期,在地面风从盛行的北风(沿航道)转向西北风(跨航道)之后。这种旋转压缩了南安普敦岛上现有的浮冰,在那里,由于海峡沿线的平静风和低潮差,浮冰保持静止,并在冷空气温度下合并。崩解发生在6月中旬至7月初融化开始后。总的来说,当一组特定的条件同时出现时,桥梁就形成了;然而,气候变暖,特别是非常寒冷的日子减少,冰季缩短可能会影响桥梁形成的频率,从而限制因纽特人的旅行。

Proposals for infrastructure development in Canada’s North are gaining political traction, including a corridor connecting the northern regions of each of the country’s provinces. Quebec is Canada’s largest, northernmost province and would be pivotal in the construction of the corridor. Examining the historical phases of Quebec’s northern development is crucial in assessing the challenges ahead. This paper groups Quebec’s infrastructure developments into three main phases, synthesizes each phase, and critically compares them to the proposed Northern Corridor concept (NCC). No research has yet examined the NCC’s complementarity with Quebec’s history of northern infrastructure development. While previous phases could be categorized as intraprovincial penetration corridors linking northern to southern Quebec, the NCC aims to develop an interprovincial economic corridor for landlocked provinces to be able to gain better sea access. Obstacles arising from the conciliation of past developments with the NCC include the unfitness of using existing infrastructures in Quebec for a Pan-Canadian corridor and differing development trajectories at the provincial and federal levels. Three route options for the NCC in Quebec are presented in this study. More generally, this paper outlines difficulties specific to subarctic remote corridor development. 
在加拿大北部发展基础设施的提议正在获得政治支持,其中包括一条连接加拿大各省北部地区的走廊。魁北克省是加拿大最大、最北端的省份,将是这条走廊建设的关键所在。考察魁北克北部发展的历史阶段对于评估未来的挑战至关重要。本文将魁北克的基础设施发展分为三个主要阶段,综合了每个阶段,并将它们与拟议的北部走廊概念(NCC)进行了批判性比较。目前还没有研究考察NCC与魁北克北部基础设施发展历史的互补性。虽然以前的阶段可以归类为连接魁北克北部和南部的省内渗透走廊,但NCC的目标是为内陆省份开发一条省际经济走廊,以便能够获得更好的海上通道。在与NCC协调过去的发展过程中产生的障碍包括不适合将魁北克现有的基础设施用于泛加拿大走廊,以及省和联邦一级的不同发展轨迹。本研究提出了魁北克NCC的三条路线选择。更一般地说,本文概述了亚北极偏远走廊发展的具体困难。
