Netflix polar bear star dies in Svalbard days after being tranquilized; her orphaned cub is shot

Early in the morning on Good Friday (7 April), a mature polar bear sow with a cub at heal was chased with snowmobiles away from a recreation area used by locals on the west coast but drowned after she escaped into the water. Her cub, likely a yearling male, attacked authorities trying to retrieve her body and was shot.

It turns out this 17 year old female was well known to locals and is considered Svalbard’s most famous polar bear. They call her ‘Frost.’ She featured in the 2019 Attenborough-narrated Netflix documentary Our Planet, in the sequence showing the stalk of a newborn ringed seal pup (see screencap above), which was likely filmed in early 2018 after the cliff-falling walrus scenes in Russia that were filmed in October 2017. h/t Sheila.

Svalbard male polar bear dies after sedation for research purposes

A 2 year old male polar bear died yesterday (10 September 2020) during the sedation procedure used by Svalbard researchers. Although most polar bear research is on hold this year due to Covid-19, apparently the annual fall research in Svalbard conducted by Norwegian biologists has been able to continue.

See details of this incident below, as screen caps; entire original in English at Polar Journal.   Continue reading

Svalbard finds tranquilizing & removing problem polar bears comes with risks to bears

In Svalbard, Norway, it is routine practice to chase polar bears away from settlements with snow machines and helicopters, then tranquilize and relocate them if necessary but in late January this approach led to the death of a young male bear.

Necropsy results released 26 March 2020 revealed that the two year old bear, who had wandered into and around Longyearbyen multiple times in late January, was captured after a prolonged helicopter chase but died enroute as it was flown north to Nordaustlandet (see map below) from circulatory failure due to administering anesthesia after the prolonged stress of being chased.

Video here of the bear being chased out of Longyearbyen by helicopter (photo above is of the New Year’s bear). Longyearbyen has had more problems than usual with polar bears this winter due to the unusually extensive sea ice off the west coast of Svalbard. Polar bears are particularly dangerous in winter and with the abundance of bears in recent years many Arctic communities are at risk with each having to find their own solutions.

In the wee hours of New Years Day 2020 a fat Svalbard polar bear was shot because of persistent visits to downtown Longyearbyen and the public was outraged. A few weeks later a bear attacked a dogsled loaded with tourists. The death of the young bear in late January in the course of removing it (rather than shooting it) is a reminder that tranquilizing a polar bear, especially after a prolonged chase, can be as lethal as shooting it.

Polar bear biologists miss the mark in new study on invasive mark-recapture effects

Apparently, some biologists think that outputs from complex computer models will convince native Arctic residents that invasive mark-recapture work has no long-term effect on the health and well-being of polar bears.

Inuit resist government requests to tag and collar polar bears in MClintock Channel

Inuit residents of Cambridge Bay in the Central Canadian Arctic are resisting requests by the Nunavut Government to tranquilize, collar and tag polar bears to assist in their population survey.

Guest Post: Invasive Research is Alive and Well in Canada

This is a guest post by Kelsey Eliasson, who blogs at Polarbearalley, with his thoughts on the issue of the invasive research involved in polar bear mark-recapture studies around Churchill, Manitoba — which, as you’ll see, is a far different situation than I described for Nunavut (previous posts here, here, and here on this topic. Map below to get you oriented).

Kelsey is a writer, artist and polar bear guide who has spent 14 bear seasons watching the polar bears of Churchill. For five years, he ran Churchill’s monthly newspaper published occasionally, the Hudson Bay Post. Currently, he divides his year between the Yukon, Churchill and, occasionally, Riverton, home of Manitoba’s largest moose statue.

Churchill is in the Western Hudson Bay polar bear subpopulation, governed by the Province of Manitoba, while the community of Arviat, also in 'Western Hudson Bay' is overseen by the Government of Nunavut.

Churchill lies in the Western Hudson Bay (WHB) polar bear subpopulation, governed by the Province of Manitoba, while the community of Arviat, also in the Western Hudson Bay subpopulation, is overseen by the Government of Nunavut – different governments, different rules – as Kelsey points out below.

Invasive Research is Alive and Well in Canada, by Kelsey Eliasson

The recent post about Foxe Basin was of particular interest to me, as I have been following the growing gap between the north and science for some time now. The stance taken by the Inuit is viewed as an inspiration by the guides over here in Churchill. For many years, we have tried to voice our deep concerns over the levels of handling and drugging that our bears (the Western Hudson Bay population) are subjected to on an annual basis.

This time last year, I tried to raise the topic for discussion after Andrew Derocher announced that ‘everything was on the table’ including feeding bears. At that time, the top polar bear researchers had sat down to discuss options for saving bears – except reducing handling and research – i.e. chasing bears down by helicopter and then shooting them with tranquilizers.

Foxe Basin aerial survey – a watershed moment for polar bear research, Part 1

While researching the population status of Foxe Basin polar bears I came across an issue that seems to have garnered relatively little attention outside the polar bear community – Inuit objections to the handling of polar bears during mark-recapture surveys and the effect of this on polar bear research in Canada.

FoxeBasin_PBSG website_Oct 2013Mark-recapture research methods routinely used by polar bear biologists became especially contentious in Foxe Basin during a population study initiated in 2007/2008, with Inuit residents voicing objections and biologists defending its practice. The following year, the mark-recapture effort was halted and an aerial survey took its place.

The aerial survey has been completed and a report on it was released in 2012 (Stapleton et al. 2012; see previous post for results) but we’ve heard very little about what happened to that mark-recapture study and why the Government of Nunavut pulled the plug on it. I plan to change that with the next couple of posts.

I’m not claiming to understand the nuances of the story because I’m only going by available documents. However, I think it’s important to shine some light on this issue since it has clearly changed the shape of polar bear research in Canada.
