New Insights into the Microbiota of the Svalbard Reindeer Rangifer tarandus platyrhynchus [PDF]

Frontiers in Microbiology, 2016
Svalbard reindeer (Rangifer tarandus platyrhynchus) is a non-migratory subspecies of reindeer inhabiting the high-arctic archipelago of Svalbard. In contrast to other Rangifer tarandus subspecies, Svalbard reindeer graze exclusively on natural sources of food and have no chance of ingestion of any crops.

Adaptation to the High-Arctic island environment despite long-term reduced genetic variation in Svalbard reindeer [PDF]

IScience, 2023
Summary: Typically much smaller in number than their mainland counterparts, island populations are ideal systems to investigate genetic threats to small populations.

A century of conservation: The ongoing recovery of Svalbard reindeer [PDF]

Journal of Wildlife Management, 2019
ABSTRACTSeveral caribou and reindeer (Rangifer tarandus) populations have experienced recent population declines, often attributed to anthropogenic stressors such as harvesting, landscape fragmentation, and climate change. Svalbard reindeer (R. t.

Assessing the Ecological Network of Svalbard Through Scaled Interaction Strength Data: Insights From a Century of Research. [PDF]

Ecol Evol
In this work, we integrate existing knowledge on interaction strengths into a conceptual model of the Svalbard Ecological Network. We also highlight current knowledge gaps and challenges in establishing a robust baseline of species interactions in the region.

Effect of wind on Svalbard reindeer fur insulation

Rangifer, 2002
The heat transfer through Svalbard reindeer (Rangifer tarandus platyrhynchus) fur samples was studied with respect to wind velocity, season and animal age. A total of 33 dorsal fur sections were investigated using a wind tunnel. Insulation varied with season (calving, summer, autumn and winter).

Retracing the Response of Rangifer to Postglacial Climate Change in Arctic Islands [PDF]

Ecol Evol
Our study examines the role of sea ice and glacial retreat in shaping the biogeography of Rangifer tarandus across Arctic islands since the last glacial period. Using mitochondrial DNA analysis and approximate Bayesian computation (ABC) modelling, we found that Arctic island dispersal occurred during the Holocene, with sea ice cover likely influencing ...

A Pilot Investigation of the Hidden Communities Associated With Dryas octopetala L. (Rosaceae) in Svalbard Using DNA Metabarcoding. [PDF]

Environ Microbiol Rep
A single marker revealed a considerable diversity of organisms associate with Dryas octopetala. The rhizosphere contains more taxa than the phyllosphere. Some taxa are cited for the first time in the Svalbard Archipelago. The use of different DNA marker will increase diversity data in the Svalbard Archipelago.

Salivary glands in Svalbard reindeer (Rangifer tarandus platyrhynchus) and in Norwegian reindeer (Rangifer tarandus tarandus)

Rangifer, 1999
<p>The aim of this investigation was to compare the size of salivaty glands in Svalbard reindeer {Rangifer tarandus platyrhynchus) and in Norwegian reindeer (Rangifer t. tarandus) in relation to feeding strategy, season and reproductive status. The mean body mass (BM, standard deviation j) in adult non-lactating female Svalbard reindeer was 72.0,

Sweat the small stuff: A review of the use of accelerometers to estimate energy expenditure in wild animals. [PDF]

J Anim Ecol
The growing use of accelerometry by ecologists to measure energy expenditure can make physiologists sweat due to its many pitfalls. This review comprehensively describes the use of accelerometry in wild animals, the successes (and failures) of calibrations and how best to estimate energy expenditure from accelerometers.
