If Santa Claus had an internal toilet he never would have found Rudolph

How the first reindeer was domesticated

Humans and reindeer have been interacting for some 60,000 years and reindeer-herds have been followed by nomadic humans for some 10-20,000 years but true domestication is much more recent. Genetic studies indicate that many domestication events probably took place but starting no more than 2-3,000 years ago. But how was the first reindeer domesticated?

“Alice Roberts: Rudolph and our early ancestors – a love story” has a plausible narrative:

I first visited the icy north of Siberia five years ago while making a BBC documentary about ancient human migrations. We were filming with indigenous Siberians of the Evenki tribe, and staying in a remote reindeer-herders camp – living in tents that were kept warm with larch stoves while it was a bone-chilling -40°C outside. (The stoves went out overnight and in the morning I would wake up to find my eyelashes stuck together with ice.)

There were reindeer all around us in the snowy, sparse larch forest. At night, they came in, walking cautiously around our tents, the thick fur behind their large hooves muffling their footsteps. One morning I wandered off into the forest to answer a call of nature. A single pure-white reindeer followed me. I wandered further and further with the reindeer following me a few paces behind. It felt as though I had made some kind of connection with this beautiful, ethereal creature. After I had done what I’d come for, I started to make my way back to camp, and wondered if the reindeer would follow me back. He didn’t. Instead, he started tucking into the yellow snow I’d created. The mystical moment was shattered. He wanted nothing more than a few salts from my urine. Later I discovered that this apparently common behaviour was enshrined in a Siberian myth about the domestication of the first reindeer: a woman who went for a wee managed to catch and tame a reindeer who, like mine, had been after the yellow snow.

I suppose that if Santa Claus had an internal toilet and was not forced outdoors to relieve himself  he never would have met up with Rudolph!!

Reindeer grazing not global warming is shifting the tree line in Torneträsk

New research shows that the advance of the tree line upwards in the Swedish mountains was due to reduced reindeer grazing and not due to any global warming.

Swedish Radio P1 reports today: (freely translated)

It is not primarily a warmer climate which causes the tree line to crawl
up in many places in the Swedish mountains. A new study from the Torneträsk area shows that there are several other factors that affect tree spread rather than just higher temperatures. Climate change plays a very minor role. It is mainly grazing reindeer, insect infestation, and several other factors that affect mountain forest coverage, rather than changing temperature conditions.
“That the tree line can go up or down or remain stationary within the same climate period has not been shown before “, says Professor Terry Callaghan, one of the researchers who carried out the study.

The tree line advanced up the mountains most during the cold period at the end of the 1960s and 1970s. It was primarily because it was a time with fewer reindeer. A warmer climate may actually have an indirect effect (to reduce the advance northwards) by adding to the number of  insects and insect infestations that can damage trees.

Many climate models expect that the forest in the tundra and other Arctic areas will expand considerably northwards in the next one hundred years because of higher temperatures. But the new research suggests that these simple assumptions can be grossly inaccurate. One must reckon with how to account for the impact of insects and grazing reindeer and moose. “It now requires that much more detailed information be added into the models”, says Professor Terry Callaghan, director of the Abisko research station.
