Inspired by the groundbreaking investigation of ice patch archaeology in Yukon Territory, the authors began exploring the Mackenzie, Selwyn, and Richardson Mountains for ice patch archaeological sites in 2000. Through remote sensing analysis, followed by intensive field surveys in the Selwyn and Mackenzie Mountains, we documented eight ice patch sites containing well-preserved archaeological artifacts and biological specimens. Twenty additional ice patches exhibit the key indicators of ice patch archaeological sites (permanent or intermittent ice and snow lenses containing caribou fecal matter, faunal material, or both), but so far these patches have not yielded artifacts. Collections from ice patches in the Selwyn Mountains include examples of three precontact hunting technologies: throwing dart (atlatl), bow-and-arrow, and snare. Atlatl technology, represented by the distal ends of two darts dating to 2410 and 2310 14C yr BP, predates bow-and-arrow technology, represented by two complete arrows, two distal shaft fragments, and a partial bow dating between 850 and 270 14C yr BP. A ground squirrel snare dates to 970 14C yr BP. Caribou dominates the faunal remains recovered from the ice patches. These data suggest that hunting on ice patches was part of a broader-spectrum summer subsistence economy focused on a broad alpine valley, known locally as K'atieh, and that hunters tended to target ice patches close to other subsistence locations in this area.

At a recent conference called Frozen Pasts, held in Trondheim, Norway, in October 2010, presentations by researchers from five continents addressed a broad sweep of human history and culture, including the archaeological remains of caribou or reindeer hunting preserved in ice patches in North America and Norway; stratified Paleo-Eskimo middens in Greenland permafrost; First World War archaeological remains melting from snow patches in the Italian Alps; the conservation of Scott's hut in Antarctica; permafrost burials of Iron Age Scythians in the Altai Mountains; and the discovery of Inca mummies in the Andes of Argentina. Linked only by their setting in the cryosphere, that part of the Earth's surface where water is frozen for at least part of the year in the form of snow, ice, or permafrost (Slaymaker and Kelly, 2007), the papers also served to catalogue the impact that global warming is having on archaeological remains. Permafrost, alpine snow patches, glaciers, and other components of the cryosphere are melting at alarming rates. The impact of these changes - altered regional climate patterns, rising sea levels, and catastrophic slope collapses from thawing permafrost, among others - are putting heritage resources at risk, requiring urgent action from archaeologists and other heritage specialists. By sharing their experiences at conferences like Frozen Pasts, archaeologists and other researchers are cataloguing these impacts while working to define a new sub-discipline: archaeology of the terrestrial cryosphere. It is in this spirit that we present this special supplement of the journal Arctic, which brings together 12 articles in the emerging field of alpine ice patch archaeology from North America and Europe. Linked by their association with either caribou or reindeer hunting or human travel in alpine environments, these articles provide a fascinating perspective on the cryogenically preserved artifacts and biological specimens being revealed by the melting of perennial snow and ice in high alpine settings. The first six papers present the findings of the Northwest Territories (NWT) Ice Patch Study, an International Polar Year (IPY) Project funded by the Government of Canada between 2006 and 2010. IPY is the largest-ever program of scientific research focused on the Arctic and Antarctic regions (Government of Canada, 2011), and its results are leading to significant advances in our understanding of the effects of climate change on the circumpolar world and its people. The Government of Canada's IPY Program envisioned an intense "pulse" of multidisciplinary research focused on two main themes: 1) climate change impacts and adaptation and 2) the health and well-being of northern Canadians. The research design advanced by the IPY Program encouraged partnerships across disciplines in order to investigate these themes in their full complexity. This approach is reflected in these papers, which explore the human, ecological, and physical dimensions of alpine ice patches in the Selwyn Mountains of the NWT. ... As the papers in this volume demonstrate, alpine ice patches can provide important baseline data on caribou population genetics and health that can be applied in future research and management. Further research is urgently required to understand ecological change and the resulting impact on heritage resources associated with these significant habitats. In conclusion, and as the papers here attest, alpine areas throughout the circumpolar North are experiencing melting at alarming rates. This rapid melting is affecting extant caribou and reindeer herds, while revealing new archaeological finds. Archaeological research has been initiated in several jurisdictions to document these changes, though in many others, work has yet to begin. As a group, the papers in this volume suggest that the phenomenon of ice patch hunting could exist anywhere where humans and caribou or reindeer interacted at some point in the past in an alpine environment; the northern Rockies, Torngats, Baffin Mountains, the Pyrenees, the Altai, and the Urals, among others, all seem like mountain environments with high potential. With this in mind, perhaps the greatest contribution this collection of papers has to offer is inspiration. (Au)

Executive Summary: To help guide development in the Canadian Arctic, Aboriginal Affairs and Northern Development Canada (AANDC) developed the Petroleum and Environmental Management Tool (PEMT). The online tool maps the sensitivities of a variety of arctic features, ranging from whales to traditional harvesting, across the Canadian Arctic. The tool is intended to aid government, oil and gas companies, Aboriginal groups, resource managers and public stakeholders in better understanding the geographic distribution of areas which are sensitive for environmental and socio-economic reasons. This document is an extension and application to the previous report 'The Petroleum and Environmental Management Tool: Risk-based analysis and cumulative effects scenarios for the Eastern Arctic' (Nunami Stantec Ltd. 2011b) (described in ASTIS record 74859). The original report explored two approaches to estimate the relative risk associated with the environmental effects of development activities; a risk based analysis of project effects, and cumulative effects scenarios. The preliminary risk based analysis and cumulative effects scenario model was developed using four Valued Components (VCs): bowhead whale, toothed whale, thick-billed murre, and commercial fisheries. This report presents results from an updated and more realistic cumulative effects scenario with updated distribution data for the original four Eastern Arctic VCs and applying the model to the remaining four VC's in the Eastern Arctic study area. Distribution data and associated sensitivity layers for all Eastern Arctic VC's were updated prior to running the model. The original four VCs included bowhead whale, toothed whale, thick-billed murre, and commercial turbot fisheries. The additional VCs considered for the Eastern Arctic study area include polar bear, Arctic char, walrus, and traditional harvest. Development scenarios were created for the High Arctic study area and the model was applied to five VCs: polar bear, narwhal, migratory birds, Peary caribou, and traditional harvest. The analysis provides an indication of relative risk of cumulative effects based on ecological, physical, political, or social thresholds for each VC. The results described in this document support earlier conclusions that the cumulative effects of development on VCs vary considerably. (Au)

The objectives of this research were to explore and evaluate the capacity for public health surveillance in a northern context and to describe epidemiological characteristics of notifiable gastrointestinal illness (NGI) in the Northwest Territories (NWT). Cases of NGI from 1991 to 2008 were obtained from the Northwest Territories Communicable Disease Registry (NWT CDR) from the Government of the NWT Department of Health and Social Services. Using NGI as a reference disease, we found that the NWT CDR serves a useful public health function but is constrained by several underlying contextual challenges which affect the availability, quality and usefulness of health data generated from the system. Innovative, informal and community-based methods may be required to address shortcomings in the surveillance data in order to effectively guide policies and public health action for northern communities. The annual average rate of NGI over the study period was 95.5 cases per 100,000. There was increased risk of NGI in children 0 to 9 years of age, males and urban residents. Seasonal patterns were observed for most years, with NGI rates peaking in the spring and fall months. Significant decreasing temporal trends in disease were also observed over the study period. There was variability in the rates of NGI with higher notifications in the southern areas compared to the northern areas of the territory suggesting the possible involvement of geographical risk factors and/or bias in the surveillance data. Various community-level risk factors for campylobacteriosis, giardiasis and salmonellosis, the three most commonly reported NGI diseases in the territory, were investigated using multivariable regression. The final models revealed that campylobacteriosis was primarily associated with traditional food-related activities, giardiasis was mainly associated with health system factors, and salmonellosis was only associated with socio-economic status. Given that these diseases are mainly of environmental origin and considering the limitations of ecological approaches, multi-level studies to confirm the causal nature of these associations are suggested for future work.

Modification of plant abundance and distribution, especially shrubs, has been predicted by warming experiments and confirmed by aerial photography analyses and land based observations in the Low Arctic. In the High Arctic, even though satellite image analyses suggest an increase in NDVI and warming experiments have had a positive effect on shrub cover, little is known about natural system responses. The arctic willow (Salix arctica Pall.) is a structuring species in these harsh environments that could induce noticeable vegetation cover changes, either by increased growth of established individuals and/or by colonization of new sites. Population size structure, seedling count and ageing were pursued on five semi-desert sites and two glacier forelands distributed in three locations in Canada (Resolute Bay, Alexandra Fjord and Sverdrup Pass) and one in Northeast Greenland (Zackenberg). Size distribution showed that recruitment was stronger on proglacial landscape even though seedling establishment was also common in some semi-desert sites. In addition, ageing of large individuals collected on the semidesert sites through dendrochronological analyses of over 200 willows established by seed, point to discrete colonization events associated to the melting of permanent snow pack. We propose that increased NDVI recorded in the High Arctic might be explained by shrub colonization of newly deglaciated areas, rather than by the increase in cover and productivity of pre-established plant communities.

Analysis techniques are proposed that allow for estimation of potential sounding uncertainty due to water mass variability based solely on high temporal and/or spatial resolution observations of either sound speed or oceanographic measurements of temperature and salinity. The techniques do not require sounding data, thus analyses can be tailored to match any survey system; this allows for pre-analysis campaigns to optimize survey instrumentation, sound speed profiling locations/rates and survey line spacing such that a desired sounding accuracy can be maintained. In addition to this, the output of the methods can provide a higher fidelity estimation of sounding uncertainty due to water mass variability as compared to existing uncertainty models in common use. The analysis techniques are used to assess an extensive oceanographic data set collected in the Canadian Arctic Archipelago (CAA) in an effort to provide water mass sampling guidelines for current and future seabed mapping efforts in the CAA. In particular, the problem of mapping while in transit is investigated with oceanographic climatological grids of temperature and salinity being examined as a potential source of sound speed information when underway sampling of the water column is not possible.

The present and future snowcover and melt patterns of Polar Bear Pass, an extensive low-gradient wetland situated in the middle of Bathurst Island, Nunavut are examined in this thesis. Measured and modelled snowcover results from 2008 and 2009 indicate that snowcover here is largely controlled by wind and topography. Exposed hilltops are blown free of much snow, while stream valleys and lee of slopes collect the most. Within the wetland itself, subtle variations in micro-topography (ponds, lakes, wet meadows, frost cracks) ensures some variability in the end-of winter snowcover and ensuing melt pattern. In addition, snowcover and melt varied across Polar Bear Pass (both east to west and north to south). Snowcover receipt in 2008 and 2009 was low in comparison to other studies, while probability and snow depletion curves indicate similar melt rates. Projected changes in northern climate (e.g. warmer temperatures, enhanced snowfall) will have an effect on the timing and duration of spring melt here. Modelled results indicate that the snowfree season could be increased by up to three weeks at Polar Bear Pass. Future spatial and temporal changes in snowmelt could have potential consequences on the timing of other hydrologic processes such as runoff, ground thaw and evaporation loss as well as vegetation communities at Polar Bear Pass.

In mid-September 2007 the STAR (Storm Studies in the Arctic) project assembled and installed 10 surface weather stations in Iqaluit and surroundings; 4 of the stations were equipped with Iridium satellite phones to allow daily data transfer to a base station at York University, while data from other stations were retrieved when those stations were removed in April 2008. Statistics of the Wind Speed and Wind Direction data (histograms and Gamma distribution fits plus wind rose plots) illustrate the behaviour of the wind and indicate strong topographic channelling of flow in NW-SE directions along the axis of Frobisher Bay and the Sylvia Grinnell River valley.

Schedules of breeding activity and mortality of Common Eiders were monitored daily during annual avian cholera epidemics (2004-2008) at East Bay Island in northern Hudson Bay, Canada, to assess variation in disease dynamics within and among years. Dates of first mortalities and annual mortality were not related to host density, but total mortality increased with epidemic duration, peaking at over 30% in 2006 and 2008. Risk of mortality increased throughout each season and rose most steeply in 2005 when only bacterial serotype 1 caused deaths, unlike in subsequent years when serotype 3x4 was present. Restraint duration did not prevent breeding, but delayed egg-laying and increased the probability of death in 2007, but not in 2008 when restraint duration was reduced. These findings suggest that exposure duration, bacterial serotype, and stressors which can enhance susceptibility should be considered important in understanding avian cholera outbreaks. (Au)

Mercury (Hg) is a known neurotoxin that is often found in concentrations exceeding safe consumption guidelines in aquatic biota. This is especially evident in northern Canada, where northerners typically consume significant amounts of edible tissues of animals such as beluga, seals and burbot. In the Mackenzie River Basin, recent increases in Hg concentration in many of these animals over the past 25 years have been observed, although no definite reasons for this have been ascertained: atmospheric Hg levels have remained stable or slightly decreasing, and other factors (e.g., age, trophic level) do not always explain the higher biotic Hg concentrations. The warming climate, and with it, the changing carbon cycle, are hypothesised in this thesis to play a role in the increases, with increasing amounts of labile, algal-derived organic matter (OM) able to scavenge water column Hg, thus rendering it more bioavailable. Within the context of the two major zones (mountainous and peatland), with distinct geomorphology, hydrology and geology, traditional fossil fuel exploration methods (Rock-Eval pyrolysis, organic petrography) have been employed in a novel manner on recent sediments to qualify and quantify the OM and several geochemical analyses (Hg, dissolved organic carbon (DOC), SO4--, Cl-, sequential extractions) have been used to determine the geochemical sources of Hg. The mountainous zone is composed mostly of refractory OM, primarily from forest fire char and heavily reworked OM. It also contains, and fluxes, most of the Hg, which derives from oxidative weathering and erosion of widespread sulfide minerals. However, Hg from this zone is in chemical forms that are of limited bioavailability. The peatland zone has a greater proportion of labile OM, with higher concentrations of DOC and algal-derived OM. Lake-fed tributaries in this zone contain even higher proportions of labile OM. Indeed, significant correlation exists between Hg and labile OM at these sites, suggesting a correspondingly higher bioavailability. At one of these sites (Hare Indian Lake), the sediment core record shows that Hg has been increasingly associated with labile OM over time, due to increasing primary productivity, accelerated by climate change, and is resulting in an increase in scavenged Hg. The temporal trend in algal-bound Hg in the sediment record matches very well with the temporal trend of Hg in burbot sampled from the area, providing one of the first and strongest lines of evidence for the climatic impact on Hg bioaccumulation in Arctic ecosystems.

Annually and subannually laminated lacustrine sediments potentially contain a wide range of information that can be interpreted for paleoenvironmental reconstructions. These laminae are produced by the physical and biological processes that operate in the lake and in the surrounding terrestrial environment. However, identification of the influences that control laminae production may not be straightforward, and other processes may subtly influence the overall depositional sequence. This thesis examines two different depositional environments on Colin Archer Peninsula, Devon Island, Canada, with the objective of identifying the factors that influence subannual sediment deposition and how the resultant sedimentary structures can be used as indicators of paleoenvironmental conditions. In proglacial Lake R, clastic sediment deposition is controlled primarily by subannual meteorological conditions. Periods of positive air temperature or large rainfall events produce discernable laminae that, when combined, form a varve sequence. However, overarching geomorphic controls influence the delivery of sediment to the lake and may reduce or enhance the hydrometeorological signal contained in the varves. An additional influence for calibration of the varve record to meteorological observations is the role that melt season thermal inversions have on temperature extrapolation in the High Arctic. Meteorological stations at sea level may not be representative of the surrounding region, thereby reducing the accuracy of vertical temperature estimation. Investigation of the inversions in the central Canadian High Arctic demonstrated that melt season inversions are common and increased inversion frequency may potentially have influenced enhanced glacial melt since the late 1980s, with implications for proglacial lake sediment transport and deposition. In coastal Lake J, late Holocene sediments record a relatively unusual accumulation of microbially induced sedimentary structures (MISS). Such a record has not been previously described in the circum-Arctic, although they are known to exist elsewhere. These sediments are produced by the interaction between clastic sedimentation and cyanobacterial growth and production. Although chronological constraint could not be assigned with certainty to the record, statistical study of the laminated sequence suggested a dominant pattern that is plausibly annual. A heuristic model of annual sediment accumulation was developed in order to explore the potential for quasi-annual paleoenvironmental interpretations. (Au)

Lors de la dernière déglaciation au Wisconsinien supérieur, la région de la côte est de la baie d'Hudson a subi une transgression marine (mer de Tyrrell) synchrone au recul des glaces continentales de l'Inlandsis laurentidien vers le centre du Québec nordique. Le relèvement glacio-isostatique postglaciaire a provoqué l'émersion d'importantes masses sédimentaires déposées dans cette mer. L'étude morphologique et stratigraphique de ces dépôts a permis de reconstituer les étapes de la déglaciation ainsi que les différentes phases du retrait de la mer. Dans la région de la rivière Biscarat, des indices d'une stabilisation temporaire de la marge glaciaire ont été retrouvés dans les collines côtières, à environ 7 km de la côte. Ce système est la continuité vers le nord de la « Nastapoka drift belt » dont l'âge a été évalué à 8 ka BP. Une autre pause ou ralentissement du front a été observée à l'est de la limite de l'invasion marine à l'intérieur des terres. (Au)

Les impacts du réchauffement climatique observés dans l'Arctique canadien ont le potentiel d'influencer la santé des communautés inuites, notamment en modifiant la sécurité alimentaire. La présente étude vise à documenter les observations et les perceptions de chasseurs et de pêcheurs expérimentés à propos de l'implication des changements climatiques pour la diète de leurs ménages sous une approche de vulnérabilité (Turner et al. 2003). Les entrevues semi-structurées (n=20) ont été réalisées à l'automne 2006 avec la communauté de Kangisualujjuaq au Nunavik. Bien que tous les participants aient rapporté des impacts des changements environnementaux sur l'accès, la disponibilité et la qualité des aliments traditionnels, un peu plus de la moitié considèrent être toujours ou souvent satisfaits de la quantité de nourriture collectée. Ces résultats suggèrent que certains ménages disposent de stratégies d'adaptation efficaces, ce qui constitue d'intéressantes avenues quant à l'orientation des mesures visant à faciliter l'adaptation des groupes plus vulnérables.

Based on the analysis of otolith microstructure, arctic cod larvae and pelagic juveniles (20-55 mm standard length) sampled in September in the Laptev Sea (Siberian Arctic Ocean) were hatched under the sea-ice cover from mid-March to early July in 2003 and from early January to early July in 2005. During the Polar night in January and February 2005, frequent winter polynyas (mesoscale areas of open water amidst the ice cover) likely provided the larvae with the minimum light necessary to detect and capture plankton prey at first feeding. The absence of survivors from January to mid-March 2003 coincided with a low occurrence of polynyas. On average, arctic cod 60-171 days old were 4-mm longer at a given age in 2005 than in 2003, a difference arising early in larval life and reflecting faster growth and more frequent winter-spring polynyas in 2005. Earlier hatching and faster growth resulted in young-of-the-year arctic cod on average 8.6 mm longer in September 2005 (34.8 mm) than in September 2003 (26.2 mm). Assuming that a larger pre-winter size provides protection against predation, the increasing frequency of winter-spring polynyas on the immense Siberian Shelves could improve early survival and population size in arctic cod.

Predicted changes in Arctic climate include decreased sea-ice extent, increased storm frequency, and sea-level rise. The western Canadian Arctic is highly sensitive to sea-level rise and climate change due to high ground ice concentrations in unlithified sediments, increased storm effectiveness, decreased sea-ice extent, and high erosion rates. The southwest coast of Banks Island has similar climate conditions, substrates and ground ice contents. Publicized community concern about changing coastal conditions led to Sachs Harbour, NWT being chosen as one of the first coastal sites for detailed study as part of an ArcticNet project. Sachs Harbour and the southwest coastline of Banks Island is dominated by low unlithified coastal bluffs containing segregated ice lenses and ice-rich silty sand horizons. Initial investigations identified three possible mechanisms for coastal erosion: wave activity and storm events, rising sea level and decreasing sea-ice extent, and increased thermal ablation coupled with regional submergence. Thirty-one coastal surveys, nearshore bathymetric surveys, and sediment samples were used to determine present coastal processes and rates change. Suspended particulate matter before and after a precipitation event were used to determine the effectiveness of runoff. Aerial photographs and satellite images were used to determine historical change along the coastline and within the community. Sea ice and storm records were analysed from the 1950s to present in order to determine the frequency of events and the associated sea-ice conditions. Coastal bluffs along the southwest coast are undergoing retreat at variable rates, dependant on ice content within sediments. Two main areas of retreat occur, to the west of Martha Point in an area of exposed ground ice with retreat rates of 5.9 m since 2003, and to the southeast of the community where fine grained sediment and narrow beaches leave the bluffs exposed. Within Sachs Harbour, most coastal bluffs are not presently retreating with the exception Line 2 which is retreating approximately 0.40 m/a. Storm records for Sachs Harbour indicate that event frequency throughout the record varies, with declining storm frequency since 2000. Due to the presence of sea ice in the region during the open-water season, storm events often have limited fetch which minimizes the impact on the southwest coast. Aerial photograph and satellite image analysis have indicated four major depositional areas, Sachs Spit, Martha Point Spit, Sachs Landing Beach, and Cape Kellett Spit. Areas of erosion include, west of the Martha Point Spit, within the community, and to the southeast of the community. Sediment transport is a complex. There are two major sediment transport cells, a large cell toward the west and a smaller cell moving sediment towards the community. As thermal erosion is the dominant mechanism of coastal change in Sachs Harbour and throughout the study area, armouring or other anthropogenic measures to prevent erosion within the community will be ineffective. As the community is fronted by a large beach, community expansion on the coastal bluffs is not advisable. With warming conditions in the region, thermal retreat will continue and as sea ice extent decreases, the effectiveness of storm events of eroding this coastline will increase. (Au)

Microbial mats exist in freshwater pools atop the Ward Hunt and Markham ice shelves in the Canadian high Arctic. In this study, culture-dependent and culture-independent techniques were used to describe the microbial diversity and activity of these mat communities. Bacterial and archaeal 16S rRNA gene clone libraries were constructed from Markham and Ward Hunt mat samples. Bacterial libraries from both mats had high diversity, though the Markham library appeared more diverse than the Ward Hunt library. Over 95% of sequences in both bacterial libraries, and all isolates from both mats, grouped within the phyla Bacteroidetes, Proteobacteria, and Actinobacteria. Archaeal diversity appeared low in both mats. Only one phylotype, potentially representing a novel Euryarchaeota, was observed in both archaeal libraries. Populations in both communities showed activity at subzero temperatures, with growth of isolates at -5°C and detectable metabolic activity at -10°C, measured by radiorespiration assays of mat microcosms.

Au Nunavik, la dégradation du pergélisol est maintenant inévitable et elle devient problématique pour l'intégrité des infrastructures de transport appartenant au Ministère des Transports du Québec (MTQ). Depuis quelques années, le MTQ s'interroge sur la façon d'adapter ses infrastructures à la nouvelle réalité climatique. L'objectif principal de cette étude est de développer une stratégie réaliste d'adaptation des infrastructures de transport du Nunavik affectées par le réchauffement climatique. Actuellement, la condition des pistes et des chemins d'accès est généralement acceptable. Cependant, des problèmes ont été observés sur quelques pistes et chemins d'accès et certains pourraient devenir critiques. Les techniques de protection du pergélisol ayant un potentiel d'application intéressant sont : les remblais à convection d'air, le drain thermique et les surfaces réfléchissantes. Enfin, une nouvelle solution d'adaptation, le drain thermique, a été développée et son efficacité a été démontrée en laboratoire. Cette nouvelle technique permet de retarder la dégradation du pergélisol par extraction de chaleur durant l'hiver. Il a aussi été possible d'établir les paramètres nécessaires à la modélisation du drain thermique. (Au)

Behavioural studies of predator and prey are often made difficult by inability to quantify key parameters (e.g. prey densities) necessary for testing predictions derived from theoretical models. This is especially true of multi-species systems where trophic interactions are complex, and in habitats where observation of behaviour is hindered by complex habitat structure (e.g. dense vegetation, irregular terrain), limited accessibility (e.g. marine systems), low densities of species of interest, large-scale movement patterns, periods of darkness, and situations where foraging and reproduction are spatially segregated. Studies can also be compromised by disturbance (e.g. visits by researchers). Selection of a simple system in combination with different data gathering approaches can create opportunities for understanding behaviour, and sources of temporal and spatial variation. I studied predator-prey interaction, focussing on the relationship between breeding herring gulls (Larus argentatus) and their common eider (Somateria mollissima) prey at the East Bay Migratory Bird Sanctuary in the eastern Canadian Arctic. At this location, herring gulls are distributed on a low-lying coastal plain and on a small treeless colony island with common eiders. Here, the relative simplicity of species assemblages, long daylight periods, lack of tall vegetation, quantifiable predator and prey densities, and behavioural, foraging and breeding parameters, make conditions ideal for gathering empirical data essential in exploring theoretical models of foraging behaviour. I found that herring gulls modified their foraging activity in accordance with predictions derived from Optimal Foraging and Alternative Prey models. Specifically, gulls searched more when net costs of foraging were reduced, and gull foraging intensity was highest in low lemming-abundance years. I also found that gull foraging decisions were modulated by risk of injury from aggressively defensive eider females. For example, gulls attempting to capture eider ducklings took more risks (i.e. were more likely to elicit aggressive defensive response from adult females) during years when lemming abundance was low. However, if environmental conditions were not conducive to lower-risk attack modes, likelihood of gull attack success was greatly reduced. Lastly, by way of a food supplementation experiment, I found that gull territorial attendance varied in relation to prey abundance within their respective territories, and that pair members allocated time within territorial boundaries in a way that increase defence of prey resources. This demonstrated that food resources within territories contributed to determining the proportion of time used toward extraterritorial forays. I found that environmental conditions, risks of injury from reactive prey, differences in relative availability of prey arising from prey behaviour, the availability of alternative prey, and gull territorial behaviour, influenced gull foraging behaviour.

D'octobre 2002 à septembre 2004, la température de l'air ainsi que la vitesse et la direction des vents ont été mesurées dans les environs de la vallée de Salluit (Nunavik). Durant la même période, la température de la surface du sol a été mesurée dans 18 sites représentatifs des conditions topographiques rencontrées dans la vallée: relief, couvert de neige, nature du sol, proximité d'infrastructures. Les résultats montrent que la variabilité thermique dans l'air et à la surface du sol s'est avérée moins grande durant la deuxième année de mesure et que l'enceinte de la vallée possède son climat propre qui se manifeste en fonction des conditions atmosphériques régionales. Par ailleurs, les indices thermiques de gel et de dégel compilés à la surface du sol indiquent que la vallée est morcelée en une mosaïque de surfaces microclimatiques qui influencent le bilan thermique de la partie supérieure du pergélisol.
