| blood and urinary cadmium levels in inuit living in kuujjuaq, canada. | blood and urine cadmium concentrations have been determined in a group of 85 inuit residents of kuujjuaq, quebec, canada, drawn from actively hunting households. mean blood cadmium values are high at 39.4 nmol/l, varying between 6.6 in non-smokers and 60.3 in smokers. no association of blood cadmium with self-reported offal consumption could be found. median urine cadmium concentrations are elevated at 2.3 mumol/mol creatinine and rise substantially with age: 0.9 in the 30-39 age group; 3.2 amon ... | 1992 | 1362287 |
| an outbreak of toxoplasmosis in pregnant women in northern québec. | an ongoing screening program for toxoplasmosis identified a cluster of four women from northern québec who, over a 4-month period, seroconverted during their pregnancy. an epidemiologic investigation was carried out in an attempt to identify the source of this infection. all potential risk factors were assessed by a questionnaire administered to 22 inuit women who had delivered babies in the previous year. seroconversion was significantly associated with skinning of animals for fur (p = .015) an ... | 1990 | 1969458 |
| variation in cadmium content of caribou tissues from northern québec. | samples of kidney, liver, skeletal muscle, heart, mesentery and rumen wall were collected during 1985-1986 in northern québec from 121 caribou belonging to the rivière george herd. significant seasonal variations were found for cadmium concentration in kidneys, liver and skeletal muscles, the level being higher in winter than in autumn. the concentration in liver and kidneys increased with age, while the effect of this factor was complex in skeletal muscles. sex-related differences were found in ... | 1989 | 2569761 |
| food-borne botulism in canada, 1971-84. | sixty-one outbreaks of food-borne botulism involving a total of 122 cases, of which 21 were fatal, were recorded from 1971 to 1984 in canada. most occurred in northern quebec, the northwest territories or british columbia. of the 122 victims 113 were native people, mostly inuit. most of the outbreaks (59%) were caused by raw, parboiled or "fermented" meats from marine mammals; fermented salmon eggs or fish accounted for 23% of the outbreaks. three outbreaks were attributed to home-preserved food ... | 1985 | 2866023 |

| cadmium in caribou and muskoxen from the canadian yukon and northwest territories. | cadmium, zinc, copper and metallothionein concentrations were measured in liver and kidney tissue of caribou and muskoxen collected from various sites in the canadian yukon and northwest territories. cadmium concentrations in caribou tissues were substantially higher than in muskoxen for all age classes and were comparable to concentrations reported for caribou from northern québec and norway. no geographical site differences in cadmium concentration were observed. cadmium concentrations were po ... | 1994 | 7911600 |
| spatial and temporal trends of contaminants in canadian arctic freshwater and terrestrial ecosystems: a review. | the state of knowledge of contaminants in canadian arctic biota of the freshwater and terrestrial ecosystems has advanced enormously since the publication of the first major reviews by lockhart et al. and thomas et al. in the science of the total environment in 1992. the most significant gains are new knowledge of spatial trends of organochlorines and heavy metal contaminants in terrestrial animals, such as caribou and mink, and in waterfowl, where no information was previously available. spatia ... | 1999 | 10466229 |

| long-term interactions between migratory caribou, wildfires and nunavik hunters inferred from tree rings. | barren-ground caribou (rangifer tarandus) herds in north america may reach considerable size and undertake large-scale seasonal migrations from the arctic tundra to the boreal forest. to test the caribou decline hypothesis associated with native harvesting and fire, we have documented the long-term trends of caribou activity based on a novel approach which uses tree-ring dated trampling scars produced by caribou hooves in the extensive trails distributed over the summer and winter ranges of the ... | 2004 | 15666677 |
| radiocesium in caribou and reindeer in northern canada, alaska and greenland from 1958 to 2000. | this study summarizes the spatial and temporal trends of fallout (137)cs concentrations in caribou and reindeer (rangifer tarandus ssp.), reported in various programs in canada, alaska and greenland, over a 40-y period. during the 1960s, the highest (137)cs concentrations (2000-3000bqkg(-1) wet weight in muscle) were found in the large caribou herds of central northern canada, with levels about 50% lower in alaska and greenland. concentrations varied by up to a factor of 6 between spring and fal ... | 2007 | 17239506 |
| re-evaluation of blood mercury, lead and cadmium concentrations in the inuit population of nunavik (québec): a cross-sectional study. | arctic populations are exposed to mercury, lead and cadmium through their traditional diet. studies have however shown that cadmium exposure is most often attributable to tobacco smoking. the aim of this study is to examine the trends in mercury, lead and cadmium exposure between 1992 and 2004 in the inuit population of nunavik (northern québec, canada) using the data obtained from two broad scale health surveys, and to identify sources of exposure in 2004. | 2008 | 18518986 |
| influence of forage preferences and habitat use on 13c and 15n abundance in wild caribou (rangifer tarandus caribou) and moose (alces alces) from canada. | stable isotope composition (delta(13)c and delta(15)n) of moose (alces alces) and caribou (rangifer tarandus) hair from the boreal forest of jacques-cartier park and cote-nord (quebec) and arctic tundra of queen maud gulf and southampton island (nunavut) was investigated as an indicator of dietary preferences and habitat use. values of delta(13)c(hair) and delta(15)n(hair) in moose were consistently lower compared to those of caribou. this is consistent with the depletion in (13)c and (15)n in t ... | 2010 | 20229388 |
| variables associated with besnoitia tarandi prevalence and cyst density in barren-ground caribou (rangifer tarandus) populations. | besnoitia tarandi has been documented in free-ranging reindeer and caribou (rangifer tarandus spp.) since 1922 throughout their arctic and subarctic ranges; however, very little is known about its epidemiology. we evaluated variables associated with b. tarandi prevalence and cyst density with the use of barren-ground caribou (rangifer tarandus) from two migratory herds in northern quebec: the rivière-aux-feuilles and the rivière-george herds. diagnosis of infection was made upon the microscopic ... | 2013 | 23307369 |
| temporally dynamic habitat suitability predicts genetic relatedness among caribou. | landscape heterogeneity plays a central role in shaping ecological and evolutionary processes. while species utilization of the landscape is usually viewed as constant within a year, the spatial distribution of individuals is likely to vary in time in relation to particular seasonal needs. understanding temporal variation in landscape use and genetic connectivity has direct conservation implications. here, we modelled the daily use of the landscape by caribou in quebec and labrador, canada and t ... | 2014 | 25122223 |
| nitrogen allocation to offspring and milk production in a capital breeder. | nitrogen (n) is a limiting nutrient for many herbivores, especially when plant availability and n content are low during the period of maternal investment, which is common for arctic ungulates. we used natural abundance of n isotopes to quantify allocation of maternal nitrogen to neonatal calves and milk in wild migratory caribou (rangifer tarandus). we contrasted female-calf pairs from two herds in northern quebec/labrador, canada: rivière-george herd (rg; low population size with heavy calves) ... | 2013 | 24015525 |
