Diet of Arctic Wolves on Banks and Northwest Victoria Islands, 1992-2001
Diet of Arctic Wolves on Banks and Northwest Victoria Islands, 1992-2001 Nicholas C. Larter Department of Environment and Natural Resources Government of the Northwest Territories 2013 Manuscript Report No. 230 The contents of this paper are the sole responsibility of the author. i ii ABSTRACT As part of a larger study, wolf stomachs were collected from entire wolf carcasses collected by local harvesters from Sachs Harbour (71°59’N 125°15’W) on Banks Island from 1992-2001, and from Ulukhaktok, formerly Holman (70°45’N 117°42’W) on Northwest Victoria Island from 1998-2001. Wolf scats were collected opportunistically during field research trips conducted on Banks Island from 1993-2001 and on Northwest Victoria Island from 1998-1999. A total of 129 stomachs and 38 scats from Banks Island, and 30 stomachs and two scats from Northwest Victoria Island were analyzed macro and microscopically for hair, feather, and bone fragments of prey items. Prey items were identified as closely as possible to species. Seventeen stomachs were empty. Remains of muskoxen (Ovibos moschatus) predominated being found in 90% of 115 and 88% of 27 stomachs from Banks Island and Northwest Victoria Island, respectively, and 87% of 38 and 100% of two scats from Banks Island and Northwest Victoria Island, respectively. Peary caribou (Rangifer tarandus pearyi), collared lemming (Dicrostonyx torquatus), Arctic hare (Lepus arcticus), Arctic fox (Alopex lagopus), snow goose (Chen caerulescens), ptarmigan (Lagopus spp.), and plant material were also found in stomachs and scats; however, only Peary caribou and collared lemming occurred in ≥5% of either stomachs or scats. -
Soil Thermal and Ecological Impacts of Rain on Snow Events in the Circumpolar Arctic
2302 JOURNAL OF CLIMATE VOLUME 22 Soil Thermal and Ecological Impacts of Rain on Snow Events in the Circumpolar Arctic KEVIN J. RENNERT Department of Atmospheric Sciences, University of Washington, Seattle, Washington GERARD ROE AND JAAKKO PUTKONEN Department of Earth and Space Sciences, University of Washington, Seattle, Washington CECILIA M. BITZ Department of Atmospheric Sciences, University of Washington, Seattle, Washington (Manuscript received 26 June 2007, in final form 22 January 2008) ABSTRACT Rain on snow (ROS) events are rare in most parts of the circumpolar Arctic, but have been shown to have great impact on soil surface temperatures and serve as triggers for avalanches in the midlatitudes, and they have been implicated in catastrophic die-offs of ungulates. The study of ROS is inherently challenging due to the difficulty of both measuring rain and snow in the Arctic and representing ROS events in numerical weather predictions and climate models. In this paper these challenges are addressed, and the occurrence of these events is characterized across the Arctic. Incidents of ROS in Canadian meteorological station data and in the 40-yr ECMWF Re-Analysis (ERA-40) are compared to evaluate the suitability of these datasets for characterizing ROS. The ERA-40 adequately represents the large-scale synoptic fields of ROS, but too often has a tendency toward drizzle. Using the ERA-40, a climatology of ROS events is created for thresholds that impact ungulate populations and permafrost. It is found that ROS events with the potential to harm ungulate mammals are widespread, but the large events required to impact permafrost are limited to the coastal margins of Beringia and the island of Svalbard. -

Beerling b a School of Earth and Environment, University of Leeds, LS2 9JT, UK b Department of Animal and Plant Sciences, University of Sheffield, S10 2TN, UK Received 19 January 2006; received in revised form 8 July 2006; accepted 16 July 2006 Available online 19 October 2006 Abstract Permineralised conifer wood is abundant in Cretaceous (Albian–Aptian) sediments in high northern latitudes (N60°). The wood provides evidence of conifer-dominated forests that extended across the northern polar regions during greenhouse periods when the climate was warmer than today. This study investigates the composition of the Cretaceous (Albian–Aptian) high latitude Northern Hemisphere conifer forests using wood from Spitsbergen, and Ellesmere and Axel Heiberg islands in the Canadian Arctic Archipelago. Identification of the fossil woods indicates that the conifers included Pityoxylon, Piceoxylon, Laricioxylon, Protopi- ceoxylon, Palaoepiceoxylon, Taxodioxylon, Juniperoxylon, Protocedroxylon, Araucariopitys, Xenoxylon, Cupressinoxylon and Taxaceoxylon. This study shows that Spitsbergen was dominated by Taxodioxylon (25%) and in the Canadian Arctic Pityoxylon (33%) was dominant. Climate analysis of the conifers indicates that the northern Cretaceous (Albian–Aptian) forests of Svalbard grew in moist cool upland areas with warmer temperate areas in the lowlands, probably with rivers and/or swampy areas present. The forests of the Canadian Arctic probably grew under slightly cooler conditions than on Svalbard, similar to northern Canada today. © 2006 Published by Elsevier B.V. -
A Pingo in the Mala River Valley, Baffin Island, Northwest Territories, Canada GEORGE W
244 NOTE A Pingo in the Mala River Valley, Baffin Island, Northwest Territories, Canada GEORGE W. SCOTTER' ABSTRACT. A single pingo is located onan alluvial fan within the deeply incisedMala River valley of the Borden Peninsula, Baffin Island. Its for- mation appears to be related to the abandonment of the river channel due to the influx of alluvium from a tributary stream. RÉSUMÉ. Un seul pingo est situé dansun cône alluvial dans la valléetrbs entaillée de la rivière Mala dans la péninsule Bordensur l'île de Baffin. Sa création semble être reliée A I'abandonnement du lit de la rivibre en raison de l'afflux d'alluvion provenant d'un ruisseau tributaire. Traduit pour le journal par Maurice Guibord. INTRODUCTION Two types of pingos, open-system and closed-system, have been described. Open-system pingos develop when hydraulic pressure causes intra- or sub-permafrost groundwater from an area upslope to emerge in a valley at a site of thin permafrost. They are common in the discontinuous permafrost zone of Alaska and Yukon (French, 1976; Washburn, 1979). Closed- system pingosoccur where permafrost is aggrading in a water- saturated soil. The water is expelled from the freezing soil if the soil is coarse-grained and eventually freezes into an icy pingo core. Numerous closed-system pingos in the Mackenzie Delta have developed in rapidly drained lake beds (Mackay, 1973, 1979), but in rare cases closed-system pingos may be associated with shifting river channels (Craig, 1959; Pissart and French, 1976; French and Dutkiewicz, 1976). The distribution of pingos in Canada has been summarized by Brown and Péwé (1973). -

Although numerous bacteria isolated from hydrocarbon-contami- nated sites in Antarctica were able to demonstrate promising outcomes in utilising hydrocarbon components as their energy source, reports on the utilisation of hydrocarbons by strains isolated from pristine Antarctic soil are scarce. In the present work, two psychrotolerant strains isolated from Antarctic pristine soil with the competency to utilise die- sel fuel as the sole carbon source were identifed and optimised through conventional and response surface method. Results: Two potent hydrocarbon-degraders (ADL15 and ADL36) were identifed via partial 16S rRNA gene sequence analysis, and revealed to be closely related to the genus Pseudomonas and Rhodococcus sp., respectively. Factors afecting diesel degradation such as temperature, hydrocarbon concentration, pH and salt tolerance were studied. Although strain ADL36 was able to withstand a higher concentration of diesel than strain ADL15, both strains showed similar optimal condition for the cell’s growth at pH 7.0 and 1.0% (w/v) NaCl at the conventional ‘one-factor-at-a-time’ level. -
Norwegian Arctic Expansionism, Victoria Island (Russia) and the Bratvaag Expedition IAN GJERTZ1 and BERIT MØRKVED2
ARCTIC VOL. 51, NO. 4 (DECEMBER 1998) P. 330– 335 Norwegian Arctic Expansionism, Victoria Island (Russia) and the Bratvaag Expedition IAN GJERTZ1 and BERIT MØRKVED2 (Received 6 October 1997; accepted in revised form 22 March 1998) ABSTRACT. Victoria Island (Ostrov Viktoriya in Russian) is the westernmost island of the Russian Arctic. The legal status of this island and neighbouring Franz Josef Land was unclear in 1929 and 1930. At that time Norwegian interests attempted, through a secret campaign, to annex Victoria Island and gain a foothold on parts of Franz Josef Land. We describe the events leading up to the Norwegian annexation, which was later abandoned for political reasons. Key words: Franz Josef Land, Victoria Island, Norwegian claim, acquisition of sovereignty RÉSUMÉ. L’île Victoria (en russe Ostrov Viktoriya) est l’île la plus occidentale de l’Arctique russe. En 1929 et 1930, le statut légal de cette île et de l’archipel François-Joseph voisin n’était pas bien défini. À cette époque, les intérêts norvégiens tentaient, par le biais d’une campagne secrète, d’annexer l’île Victoria et d’établir une emprise sur des zones de l’archipel François- Joseph. On décrit les événements menant à l’annexion norvégienne, annexion qui fut délaissée par la suite pour des raisons politiques.
