Climate, icing, and wild arctic reindeer: past relationships and future prospects. | Across the Arctic, heavy rain-on-snow (ROS) is an "extreme" climatic event that is expected to become increasingly frequent with global warming. This has potentially large ecosystem implications through changes in snowpack properties and ground-icing, which can block the access to herbivores' winter food and thereby suppress their population growth rates. However, the supporting empirical evidence for this is still limited. We monitored late winter snowpack properties to examine the causes and c ... | 2011 | 22073783 |
Pastoral Herding Strategies and Governmental Management Objectives: Predation Compensation as a Risk Buffering Strategy in the Saami Reindeer Husbandry. | Previously it has been found that an important risk buffering strategy in the Saami reindeer husbandry in Norway is the accumulation of large herds of reindeer as this increases long-term household viability. Nevertheless, few studies have investigated how official policies, such as economic compensation for livestock losses, can influence pastoral strategies. This study investigated the effect of received predation compensation on individual husbandry units' future herd size. The main finding i ... | 2011 | 21874081 |

Identification of a Mycoplasma ovis-like organism in a herd of farmed white-tailed deer (Odocoileus virginianus) in rural Indiana. | Mycoplasma ovis is a hemoplasma parasite of sheep, goats, and reindeer; however, natural hemoplasma infection in white-tailed deer has not previously been reported. Subsequent to finding many coccoid, bacillary, and ring-shaped organisms, consistent with hemotropic mycoplasmas, on RBCs from a 72-day-old female white-tailed fawn, we sought to (1) identify the putative hemoplasma observed in blood from the fawn, (2) evaluate others in the herd for hemoplasma infection, and (3) identify clinicopath ... | 2011 | 22112325 |
fatty acids, antioxidants and oxidation stability of processed reindeer meat. | the effect of hot smoking and drying on reindeer meat (m. semimembranosus) was investigated with regard to vitamin content, fatty acids (fa), lipid oxidation and lipolysis. in smoked and dried meat, free fatty acids were found to increase (p<0.001), whereas polar lipids, cholesterol and triacylglycerols decreased. only slight changes in fa composition of the smoked meat were found but the composition of the dried meat differed significantly from both smoked and fresh meat. fresh and smoked meat ... | 2004 | 22061528 |
Dual-energy digital radiography in the assessment of bone mechanical properties. | At present, bone fragility and fracture risk are estimated with bone mineral density (BMD), measured by dual-energy x-ray absorptiometry (DXA). It is known that DXA-based BMD (BMD(DXA)) has a relationship with mechanical characteristics of bone. Dual-energy digital radiography (DEDR) has also been shown to be a potential method to determine BMD, but the ability of DEDR-based BMD (BMD(DEDR)) to predict bone mechanical properties is not yet known. In this study, we investigated the ability of BMD( ... | 2012 | 22156238 |

averted doses to norwegian sámi reindeer herders after the chernobyl accident. | abstract-: the chernobyl fallout is an enduring challenge to reindeer husbandry in norway, and south sámi reindeer herders in central and southern norway are as contaminated by cs as inhabitants close to chernobyl. therefore, norwegian authorities continuously recommend to these reindeer herders the use of countermeasures to reduce their intake of cs. in this study, the authors have applied data on contamination levels in reindeer, results of dietary surveys, and whole body monitoring data in lo ... | 2012 | 22217593 |
tolerance of an expanding subarctic shrub, betula glandulosa, to simulated caribou browsing. | densification of the shrub layer has been reported in many subarctic regions, raising questions about the implication for large herbivores and their resources. shrubs can tolerate browsing and their level of tolerance could be affected by browsing and soils productivity, eventually modifying resource availability for the caribou. our objective was to assess the compensatory growth potential of a subarctic shrub, betula glandulosa michx., in relation with caribou browsing and nutriment availabili ... | 2012 | 23272191 |
high diversity of planctomycetes in soils of two lichen-dominated sub-arctic ecosystems of northwestern siberia. | a wide variety of terrestrial ecosystems in tundra have a ground vegetation cover composed of reindeer lichens (genera cladonia and cetraria). the microbial communities of two lichen-dominated ecosystems typical of the sub-arctic zone of northwestern siberia, that is a forested tundra soil and a shallow acidic peatland, were examined in our study. as revealed by molecular analyses, soil and peat layers just beneath the lichen cover were abundantly colonized by bacteria from the phylum planctomyc ... | 2016 | 28066382 |
herding conditions related to infectious keratoconjunctivitis in semi-domesticated reindeer: a questionnaire-based survey among reindeer herders. | infectious keratoconjunctivitis (ikc) in eurasian semi-domesticated reindeer (rangifer tarandus tarandus) is a multifactorial disease, associated to infectious agents such as cervid herpesvirus 2 (cvhv2) and various species of bacteria, but environmental factors may also be necessary to initiate the disease. little effort seems to have been invested in addressing the herder`s experience with this disease. an information letter with a link to an online questionnaire was sent to 410 herding commun ... | 2015 | 27068819 |
a new multiple-locus variable-number tandem repeat analysis reveals different clusters for anaplasma phagocytophilum circulating in domestic and wild ruminants. | anaplasma phagocytophilum is a tick-borne intragranulocytic alpha-proteobacterium. it is the causative agent of tick-borne fever in ruminants, and of human granulocytic anaplasmosis in humans, two diseases which are becoming increasingly recognized in europe and the usa. however, while several molecular typing tools have been developed over the last years, few of them are appropriate for in-depth exploration of the epidemiological cycle of this bacterium. therefore we have developed a multiple-l ... | 2014 | 25228371 |
in a warmer arctic, mosquitoes avoid increased mortality from predators by growing faster. | climate change is altering environmental temperature, a factor that influences ectothermic organisms by controlling rates of physiological processes. demographic effects of warming, however, are determined by the expression of these physiological effects through predator-prey and other species interactions. using field observations and controlled experiments, we measured how increasing temperatures in the arctic affected development rates and mortality rates (from predation) of immature arctic m ... | 0 | 26378217 |
a walk on the tundra: host-parasite interactions in an extreme environment. | climate change is occurring very rapidly in the arctic, and the processes that have taken millions of years to evolve in this very extreme environment are now changing on timescales as short as decades. these changes are dramatic, subtle and non-linear. in this article, we discuss the evolving insights into host-parasite interactions for wild ungulate species, specifically, muskoxen and caribou, in the north american arctic. these interactions occur in an environment that is characterized by ext ... | 2014 | 25180164 |
sequence analysis of bitter taste receptor gene repertoires in different ruminant species. | bitter taste has been extensively studied in mammalian species and is associated with sensitivity to toxins and with food choices that avoid dangerous substances in the diet. at the molecular level, bitter compounds are sensed by bitter taste receptor proteins (t2r) present at the surface of taste receptor cells in the gustatory papillae. our work aims at exploring the phylogenetic relationships of t2r gene sequences within different ruminant species. to accomplish this goal, we gathered a colle ... | 2015 | 26061084 |
identification and characterization of two novel viruses in ocular infections in reindeer. | a thorough understanding of virus diversity in wildlife provides epidemiological baseline information about pathogens. in this study, eye swab samples were obtained from semi-domesticated reindeer (rangifertarandus tarandus) in norway during an outbreak of infectious eye disease, possibly a very early stage of infectious keratoconjunctivitis (ikc). large scale molecular virus screening, based on host nucleic acid depletion, sequence-independent amplification and next-generation sequencing of par ... | 2013 | 23874987 |
phantoms of the forest: legacy risk effects of a regionally extinct large carnivore. | the increased abundance of large carnivores in europe is a conservation success, but the impact on the behavior and population dynamics of prey species is generally unknown. in europe, the recolonization of large carnivores often occurs in areas where humans have greatly modified the landscape through forestry or agriculture. currently, we poorly understand the effects of recolonizing large carnivores on extant prey species in anthropogenic landscapes. here, we investigated if ungulate prey spec ... | 2016 | 26865966 |
metagenomic survey for viruses in western arctic caribou, alaska, through iterative assembly of taxonomic units. | pathogen surveillance in animals does not provide a sufficient level of vigilance because it is generally confined to surveillance of pathogens with known economic impact in domestic animals and practically nonexistent in wildlife species. as most (re-)emerging viral infections originate from animal sources, it is important to obtain insight into viral pathogens present in the wildlife reservoir from a public health perspective. when monitoring living, free-ranging wildlife for viruses, sample c ... | 2014 | 25140520 |
mycoplasma ovipneumoniae--a primary cause of severe pneumonia epizootics in the norwegian muskox (ovibos moschatus) population. | the norwegian muskox (ovibos moschatus) population lives on the high mountain plateau of dovre and originates from animals introduced from greenland. in the late summers of 2006 and 2012, severe outbreaks of pneumonia with mortality rates of 25-30% occurred. during the 2012 epidemic high quality samples from culled sick animals were obtained for microbiological and pathological examinations. high throughput sequencing (pyrosequencing) of pneumonic lung tissue revealed high concentrations of myco ... | 2014 | 25198695 |
phenology and cover of plant growth forms predict herbivore habitat selection in a high latitude ecosystem. | the spatial and temporal distribution of forage quality is among the most central factors affecting herbivore habitat selection. yet, for high latitude areas, forage quantity has been found to be more important than quality. studies on large ungulate foraging patterns are faced with methodological challenges in both assessing animal movements at the scale of forage distribution, and in assessing forage quality with relevant metrics. here we use first-passage time analyses to assess how reindeer ... | 2014 | 24972188 |
risk-sensitive reproductive allocation: fitness consequences of body mass losses in two contrasting environments. | for long-lived organisms, the fitness value of survival is greater than that of current reproduction. asymmetric fitness rewards suggest that organisms inhabiting unpredictable environments should adopt a risk-sensitive life history, predicting that it is adaptive to allocate resources to increase their own body reserves at the expense of reproduction. we tested this using data from reindeer populations inhabiting contrasting environments and using winter body mass development as a proxy for the ... | 2014 | 24772280 |
johan turi's animal, mineral, vegetable cures and healing practices: an in-depth analysis of sami (saami) folk healing one hundred years ago. | the healing knowledge of a sami (saami) hunter and reindeer herder was surveyed as a window into the concepts of health, healing, and disease in early twentieth-century sapmi (northern sweden). the two books of johan turi (1854-1936)--an account of the sami (1910) and lappish texts (1918-19) were examined to determine the varieties of recorded zootherapeutic, mineral, chemical, and ethnobotanical lore, as well as the therapeutic acts, identified conditions, and veterinary knowledge included. | 2013 | 23941666 |
definition of sampling units begets conclusions in ecology: the case of habitats for plant communities. | in ecology, expert knowledge on habitat characteristics is often used to define sampling units such as study sites. ecologists are especially prone to such approaches when prior sampling frames are not accessible. here we ask to what extent can different approaches to the definition of sampling units influence the conclusions that are drawn from an ecological study? we do this by comparing a formal versus a subjective definition of sampling units within a study design which is based on well-arti ... | 2015 | 25780767 |
absence of antibodies specific to besnoitia spp. in european sheep and goats from areas in spain where bovine besnoitiosis is endemic. | besnoitia besnoiti and b. caprae, which infect bovids (cattle and antelopes) and goats, respectively, are responsible for besnoitiosis, a chronic and debilitating disease. bovine besnoitiosis is considered to be a reemerging disease in central and western europe. in addition, infection by besnoitia spp. has been reported in reindeer from sweden and finland. recently, the parasite was also detected in roe deer and red deer from spain, where an interconnection between the domestic and sylvatic cyc ... | 2017 | 27815735 |
