Genetic analyses reveal independent domestication origins of Eurasian reindeer
TL;DR: In this paper, the authors analyzed mitochondrial sequences and nuclear microsatellites in domestic and wild herds throughout Eurasia to address the origin of reindeer herding and domestication history.
Age-specific changes in different components of reproductive output in female reindeer: terminal allocation or senescence?
Robert B. Weladji,Øystein Holand,Jean-Michel Gaillard,Nigel G. Yoccoz,Atle Mysterud,Mauri Nieminen,Nils Chr. Stenseth +6 more
TL;DR: The results provided consistent evidence for general effects of senescence on most components of reproductive output and highlighted that both individual heterogeneity and reproductive costs shape female reindeer reproductive tactics.

Effects of age, density and sex ratio on reproductive effort in male reindeer (Rangifer tarandus)
TL;DR: Weight loss during the rutting season of 54 individual male reindeer Rangifer tarandus and reproductive effort was lower for young (1- to 2-year-old) than for prime-aged (3- to 5-year) males both on an absolute and relative scale, suggesting that yearling males take a more active role whenprime-aged males are absent.
Adaptive adjustment of offspring sex ratio and maternal reproductive effort in an iteroparous mammal.
Øystein Holand,Atle Mysterud,Knut Røed,Tim Coulson,Hallvard Gjøstein,Robert B. Weladji,Mauri Nieminen +6 more
TL;DR: Over the year, female weight changes was similar between the groups suggesting reindeer follow a bet-hedging strategy; reducing the quality of this year's offspring to ensure their own future reproduction and survival.
Male phenotypic quality influences offspring sex ratio in a polygynous ungulate.
TL;DR: This study suggests that harvesting, by generating a high proportion of young, small and unattractive mates, affects the secondary sex ratio due to differential allocation effects in females, and suggests sustainable management needs to consider not only the direct demographic changes due to harvest mortality and selection, but also the components related to behavioural ecology and opportunities for female choice.
