While the research is interesting, I have trouble with the assumption of the cause.

Therefore, the observed change in female reproductive behaviour could be the result of the increasing hunting pressure in the population."

Just more BS science.

There is absolutely no scholarship in that article. The hypothesis is speculative at best without a path forward. No reasoned alternatives given. Nothing but poorly shrouded anti hunting drivel. Wou love to see the published study and peer reviewed comments.

The paper (published 4 years ago) is open access - you can read it here:

Reminds me of the claims that by selectively harvesting large sheep rams we are promoting smaller horn size.

Grizz

that said it all empirical evidences lol ... but thank you for the post. we had the same kind from the same university trying to do a dtudy on the hunt of grizzly brars they complained about the non supportive attitude of hunters and hunter assiociation to find out they were anti-bear hunting ...

These analysis show you how science thinks and how wrong they can be… of course IMHO

With the number of only 62 females from 1987-2015, 0-11cubs/year.

Other possible explanations:

The cub doesn`t move from hher mother because she cant find an own home area because its already filled.
The mother has not get pregnant because her body need an extra year to feed.

Also 30-40% of the killing of bears are done by Swedish EPA in protective hunts/kills to save reindeers, they dont care if it is a mother with cubs at all its just 2-3bears to shoot. Its only ordinary hunters who have to follow the hunting law.
