Ancestor of the polar bear by any name: grizzly vs. brown bear monikers explained

Apparently, all media outlets (except Fox News) so confused the distinction between the two common names used for the ancestor of polar bears, Ursus arctos, that they got the point of a recent news story totally wrong. An Alaskan journalist explains.

Cannibalism update and insight on the timing of media hype

In my last post, I went over some of the spin and misrepresentation of fact contained in the claim by leading polar bear biologists Steven Amstrup, Ian Stirling and Andrew Derocher (Amstrup et al. 2006; Stirling and Derocher 2012) that cannibalism is on the increase because of the effects of global warming on Arctic sea ice.

I’ve had an opportunity to follow up on three points that puzzled me. Three relate to the Amstrup et al. paper that described three cases of cannibalism in the southeastern Beaufort Sea in 2004 and one to the incidents in western Hudson Bay in 2009. In the process, I found at least three more misrepresentations of fact and gained some insight on why these incidents of cannibalism were hyped so enthusiastically when they were. Continue reading

First month for Polar Bear Science – Aug, 2012

First posts went up July 26.

Total views @ Aug. 31 – 2454

Total views:
July 2012 –    567
Aug. 2012 – 1887

Over the last three weeks, views have been >600/week, an average of 91/day.

Largest spikes in readership were generated not by new posts (surprise!) but by media coverage:
1) television, newspaper and radio interviews associated with my lecture at the University of Toronto Aug. 14, “Polar Bears: Outstanding Survivors of Climate Change”;
2) one of my posts was featured at Climate Depote on Aug. 31.

I am happy to report that so far, all of the comments I have received via the “comments/tips” page have been positive.

No one has yet asked for references. So, just to be clear, I am happy to send pdfs of any references I cite in my posts (if I have them – not always available, e.g. book chapters). Simply use the “Requests” contact page. Just because you don’t have access to a university library should not mean you can’t get to the science. Don’t take my word for anything – if you have doubts about what the research papers say, go to the source. Just ask!

I felt one comment by a reader was worth posting, so with their permission, I added it to the post as an update. Another commenter sent me photos, which I happily added, noted as an update.

I’ve got some interesting posts lined up, including another book review – stay tuned.

Enjoy the rest of your long weeekend.

PS. Huge thanks to Tom Nelson for highlighting my posts and Hilary Ostrov for technical advice to this novice blogger.
