Functional immune diversity in reindeer reveals a high Arctic population at risk

Frontiers in Ecology and Evolution, 2023
Climate changes the geographic range of both species as well as pathogens, causing a potential increase in the vulnerability of populations or species with limited genetic diversity.

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.

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.

Mortality and survival of semi-domesticated reindeer (Rangifer tarandus tarandus L.) calves in northern Finland [PDF]

, 2011
During the period 1999 to 2004 the reindeer calf survival and mortality were studied in two reindeer-herding cooperatives and in five herding-groups in northern Finland, where in total 1725 calves were fitted with mortality indicating radio-transmitters ...

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 ...
