Posted onDecember 28, 2022|Comments Off on W. Hudson Bay polar bear population decline stories are unethical and ignore critical caveats
Canadian government scientists created headline news worldwide last week when they told the media that Western Hudson Bay polar bear numbers appeared to have declined by 27% between 2017 and 2021, based on a survey report that has not been made public. This is called ‘science by press release’. Its practice is rightfully considered unethical, as it is usually associated with “people promoting scientific ‘findings’ of questionable scientific merit who turn to the media for attention when they are unlikely to win the approval of the professional scientific community.”
A Reuters story (dated 23 December 2022) admits this is the case and included another critical caveat that only one news outlet I saw bothered to mention, which happened to be BBC News:
Scientists cautioned a direct link between the population decline and sea ice loss in Hudson Bay wasn’t yet clear, as four of the past five years have seen moderately good ice conditions. Instead, they said, climate-caused changes in the local seal population might be driving bear numbers down.

While researching thepopulation 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.
Foxe Basin is a large polar bear subpopulation region that encompasses the northern portion Hudson Bay into the area west of Baffin Island, see map below (courtesy IUCN Polar Bear Specialist Group).
Mark-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. Continue reading
