title: Wooden Artifacts from the Kwäday Dän Ts'ínchi Site and Surrounding Area: An Analytical Catalogue, 1999-2005

description: This dataset, text to be published as a chapter in a book, presents an analytical catalogue of the wooden artifacts collected from the Kwäday Dän Ts'ínchi site that are presently being curated in Whitehorse. The wood artifacts were recovered within an area of approximately one square kilometre around the Kwäday Dän Ts'ínchi discovery site, and were found during the initial discovery and recovery efforts that took place in 1999, or during subsequent annual monitoring visits to the site. Except for two pieces dug out of the snow/ice, all artifacts were surface finds, picked up from either the snow or ground. In an attempt to learn more about these unique pieces, including what they may have been used for, the wood artifacts are also compared to objects known from relevant archaeological and ethnographical contexts. The total count of wooden artifacts recovered numbers 23 (Table 1). This count is based on 33 recovered fragments, some of which have been refitted together, and while others although not refitted, are assumed to be part of the same artifact since they are of similar morphology and were found in very close proximity.

title: Trichinella spp larvae in muscles of 18 species of terrestrial and marine mammals collected from Nunatsiavut, Nunavik, Nunavut and Northwest Territories in northern Canada, between 2006 and 2010

description: The data set includes sample identification, species, collection location (described using one or more of the following: name of a prominent geographic feature, nearest community, latitude and longitude), date of collection, date of testing, age, sex, sample type, sample weight, larvae recovered per g of sample, and Trichinella spp or genotype recovered. Laboratory protocols are described including recovery of larvae from muscle usng a pepsin-HCl muscle digestion procedure with a double separatory funnel step to collect larvae from the digestion mixture, identification using microscopy and PCR for confirmation and determination of genotype.
description: Purpose: This project was designed to collect baseline information on the occurrence and distribution of Trichinella spp. in Arctic wildlife with emphasis on animals traditionally harvested for food by Canadian Inuit and northern Aboriginal groups. In cases where mulitple muscle samples from a large number of individul animals of the same species were available, additional testing was planned to determine species-specific preferred muscle sites (predilection sites) for localization of Trichinella larvae, as this is important in the design of sensitive and cost-effective sampling strategies. A major purpose for the study was to provide information to Public Health Agencies in the North for risk analysis, regulatory planning and public education in support of food safety initiatives.
description: Summary: Trichinellae are small parasitic roundworms that encyst in the muscles of host animals and are passed from host to host via ingestion of infected muscle tissue. Trichinella infection in humans can cause debilitating disease and occurs when live Trichinella larvae are eaten in undercooked or raw meat from infected animals.The objective of this study was to improve present knowledge on the occurrence and distribution of this parasite in Arctic wildlife, particularly in animals traditionally harvested for food by Canadian Inuit and northern Aboriginal groups. A secondary objective was to determine which muscles in an individual animal of a species harbour the most larvae. This can improve the cost-effectiveness and sensitivity of ongoing surveillance and food safety testing by limiting sample selection to those muscles that are most likely to contain larvae. An important goal was to provide information to Public Health Agencies in the North for use in the development of food safety policies and provision of scientifically sound public education. The data set includes results from18 species of terrestrial and marine mammals collected from Nunatsiavut, Nunavik, Nunavut and the Northwest Territories in northern Canada, between 2006 and 2010 as well as information on the tests used.

title: Fatty acids from multiple species of invertebrates, teleosts, elasmobranchs, and marine mammals sampled in Cumberland Sound, 2007-2009

description: Samples of macroaglae (Fucus distichus), several zooplankton species (e.g. Calanus hyperboreus, Sagitta spp.), benthic invertebrates (e.g. scallop Chlamys islandica, snail Buccinum cyaneum, clam Hiatella arctica), teleosts (herring Clupea harengus, capelin Mallotus villosus, char Salvelinus alpines, sculpin Myoxocephalus scorpioides (adults and larvae), turbot Reinhardtius hippoglossoides), two elasmobranchs (arctic skate Amblyraja hyperborea, Greenland shark Somniosus microcephalus), two pinnipeds (harp seal Pagophilus groenlandicus, ringed seal Pusa hispida) and two cetacean (beluga whale Delphinapterus leucas , narwhal Monodon monoceros) species were collected from Cumberland Sound (Nunavut). Zooplankton were sampled by surface horizontal tows and vertical hauls using a plankton net. Benthic invertebrates were sampled by ponar or dip net, herring, char and sculpin by gillnet, capelin by dip net and turbot, arctic skate and Greenland sharks by bottom long line. Marine mammals were sampled during Inuit subsistence hunts. Fatty acids were extracted from the total lipid fraction of whole zooplankton, soft tissues of benthic molluscs, muscle tissues of fish and elasmobranchs and blubber tissue of marine mammals. One exception is the Greenland shark whose liver, muscle and blood plasma were analyzed for fatty acids. Tissue samples were first freeze dried and homogenized and lipids were extracted using 2:1 chloroform:methanol. Percent total lipid (on a dry weight tissue basis) was determined gravimetrically. Fatty acid methyl esters were generated via sulfuric acid in methanol (1:100 mixture) and analyzed via gas chromatograph coupled with a flame ionization detector. Fatty acids were identified using known fatty acid standards. Samples were collected during both summer/open water (early August) and late winter/ice cover (early April) to explore seasonal changes in species' diets.
description: Purpose: As the largest fish and most prolific eater in the Arctic seas, the Greenland shark is a very unique vertebrate in the Arctic ecosystem. Given their diet, Greenland sharks hold a position in the food web similar to that of polar bears. Little is known about how these sharks behave or how their behaviour might shift in response to changes in climate. Given their importance in the Arctic food web, this project is assessing the feeding ecology and behaviour of the Greenland shark under different ice conditions to determine how different environments affect this fish. This assessment involves the analysis of fatty acids from multiple species of invertebrates, teleosts, elasmobranchs, and marine mammals sampled in Cumberland Sound in 2007, 2008 and 2009.

title: Muskrat Ecology in Old Crow Flats, Yukon, 2007-2010

description: To gain better insight into the factors responsible for among lake variation in muskrat abundance in the Old Crow Flats, we will study muskrats on as wide a range of lakes across the Flats as possible. Lake-to-lake variation in muskrat abundance will be estimated with aerial surveys of muskrat push-up density. The abundance of aquatic vegetation, as well as lake hydrological and limnological characteristics, will be documented for a subset of surveyed lakes in collaboration with other researchers involved in the project. Then, working in collaboration with Vuntut Gwitchin trappers we will obtain muskrat carcasses or selected tissues from some study lakes. Analysis of carcasses, which will be performed at McGill, the laboratories of collaborating researchers, and/or commercial labs, will involve estimation of 1) age and body size, 2) diet composition via stable isotope analysis and/or stomach content analysis, and 3) gene flow between study lakes based on microsatellite genetic markers.
description: Purpose: We seek to document lake-to-lake and year-to-year variations in muskrat aundance and condition. We also seek to understand how water level fluctuations and aquatic vegetation communities determine the local abundance and gene flow of muskrats
description: Summary: The purpose of the muskrat component of the larger YNNK IPY project is to examine relationships between environmental change, muskrat ecology, and traditional use of the Old Crow Flats. Specifically, we seek to examine how the distribution, abundance, and gene flow of muskrats in the Old Crow Flats are affected by hydrology and aquatic vegetation, both of which are thought to be major determinants of local muskrat abundance.Collectively these results will provide insight into the determinants of muskrat abundance and condition in Old Crow Flats and the sensitivity of these variables to environmental change.

title: Vegetation Succession on Drained Lakes in Old Crow Flats, 2007-2009

description: Temperature increases in northern ecosystems are altering the freqeuncy of natural disturbance. Increased disturbance is likely to exert a strong influence on terrestrial vegetation. In the Old Crow Flats in the Northern Yukon, we investigated the effect of catastrophic lake drainage on plant community composition, vegetation structure and microenvironment by contrasting drained lake basins of various ages with several undisturbed terrain types. The vegetation that develops on drained lakes basins is typically dominated by canopy forming willows. Plant community composition at these sites is significantly correlated with thaw depth, organic layer thickness, and moisture. Differences in species composition between disturbed and undisturbed sites indicate that plant communities developing on drained basins can remain distinct for approximately a century. Preliminary data analysis suggests that long-term succession may follow two principle trajectories, which likely depend on the environmental conditions following drainage. The persistence of distinct plant communities on drained lake basins suggests that an increase in the area affected by drainage will have a strong impact on both landscape heterogeneity and wildlife habitat. Additional work to characterize vegetation using fine-scale infrared photography will verify if the patterns observed in the field are also evident at the landscape scale.
description: Purpose: To describe changes in environment and plant community composition following lake drainage.

title: Concentration (fg/kg) of radioactive isotope Thorium-230 (230Th) in the Beaufort Sea at 3 stations in 2007 and at 4 stations in 2009

description: The dataset consists of 230Th concentrations (fg/kg seawater) measured in the Beaufort Sea at three stations in 2007 (Sept 22-Oct 15) and four stations in 2009 (Aug 27 - Sep 12). 20L samples were collected and quickly filtered through an Acropak cartridge (0.45 um). The samples were then acidified to pH 2 with concentrated HCl and spiked with pre-weighed quantities of 229Th and FeCl3. Acidified samples were left to equilibrate for 12 to 24 hours and their pH adjusted to 8-9 to precipitate Fe hydroxide and scavenge 230Th and 229Th. The precipitates were let to settle tover 12 to 24 hours and recovered by suction with a peristaltic pump and centrifugation into a 50 ml centrifuge tube for transport to UBC where they were measured on a Element II ICP-MS. The 2007 station locations were: KC500 (71°05'N, 134°22'W, 6 samples at 6 depths), KC2000 (71°44'N, 135°30'W, 12 samples at 12 depths), and KC2700 (72°28'N, 136°56'W, 12 samples at 12 depths). The 2009 station locations were: L1 (71°06'N, 139°10'W, 12 samples at 12 depths), L2 (74°30'N, 137°00'W, 12 samples at 12 depths), L3 (75°17'N, 137°20'W, 12 samples at 12 depths), and L1.1 (72°31'N, 136°48'W, 12 samples at 12 depths).
description: Purpose: Variations in seawater 230Th concentration with depth provide information on the flux of particles sinking to the seafloor and deep water circulation.
description: Summary: Comparing measurements made in 2007 and 2009 to measurements made by others in 1995 will document recent changes in particle flux and carbon sequestration in the deep waters of the Beaufort Sea resulting from a reduction in summer sea ice cover, and changes in deep water circulation in the Arctic Ocean.
