Caribou and Reindeer Population Cycles Are Driven by Top‐Down and Bottom‐Up Mechanisms Across Space and Time [PDF]

open access: yesEcology and Evolution
Anthropogenic change is reshaping the regulation and stability of animal population dynamics across broad biogeographic gradients. For example, abiotic and biotic interactions can cause gradients in population cycle period and amplitude, but this ...

Whole-genome sequencing provides novel insights into the evolutionary history and genetic adaptation of reindeer populations in northern Eurasia

open access: yesScientific Reports, 2023
Domestic reindeer (Rangifer tarandus) play a vital role in the culture and livelihoods of indigenous people across northern Eurasia. These animals are well adapted to harsh environmental conditions, such as extreme cold, limited feed availability and ...

Multi-isotope analysis of bone collagen of Late Pleistocene ungulates reveals niche partitioning and behavioural plasticity of reindeer during MIS 3

open access: yesScientific Reports, 2023
Here we present stable carbon, nitrogen and sulfur isotope ratios of collagen extracted from Rangifer, Equus and Bison bone (n = 128) from different stratigraphic levels at the chronologically well-constrained Middle and Upper Palaeolithic site of Les ...

Radiocesium concentrations in wild reindeer at Dovrefjell, Norway

open access: yesRangifer, 1987
Seasonal radiocesium concentrations varied about 6 times in wild reindeer following the Chernobyl accident, from 8 KBq/kg in August to 46 KBq/kg in March. These results agree with the predictions of earlier models.

Defence behaviour of reindeer in response to flying parasitic Diptera

open access: yesRangifer, 1989
Similar defence behaviours were exhibited by a reindeer when experimentally exposed to three different species of tethered, flying parasitic Diptera, Cephenemyia trompe (Modeer), Hypoderma tarandi (L) and Tabanid. Defencive behavioural responses appeared
