Do animals get bigger as the climate they live in gets colder? According to a rule established in 1847, they do – which has had biologists concerned over what climate change might do to animal body size. But now an analysis of the weights and geographical locations of nearly 274,000 individuals from 952 bird and mammal species has challenged the idea.
Bergmann’s rule, formulated in 1847 by German anatomist Carl Bergmann, states that an animal’s body size is negatively related to the temperature of its environment: smaller individuals of a species are found in hotter regions of the species’ range, while larger members reside in colder climes. Moose, for example, are supposed to get larger further north in their range.
The rule, which most often refers to populations within a species but has also been applied to differences between species within a genus, has been invoked to explain.

But Lib women who don’t use deodorant will...
What about people?.......................
Ummm....dinosaurs? Just sayin’
Correct. Animals generally get larger in warmer climates.
If it gets colder they will....just ask George...
I’ll bet it has more to do with abundance of food and how much competition there is for it than anything with temperature. When I was in Haifa, Israel the wharf rats there were the size of cats, much bigger than on the Virginia waterfront. It’s a lot hotter in Israel, how does Bergmann explain that? So much of this crap is darts at a dartboard. If somebody who made a name for themselves calls it a law, it doesn’t get questioned for 200 years.
Phew!
In the past there have been many changes of the climate. There was a glacier covering the top part of the USA down to around New York. There have been many more. The area of the current Sahara Desert was once full of vegetation.
Climate changes, and has been changing for millions of years, and none of it was caused by humans.
To accept manmade climate change is to deny the fact that the forces that led to past climate change are STILL operating.
I was sure hoping that new Global Warming Diet would work.
Been waiting over 30 years for it to show up.
.
Just some parts of people.... but usually the condition is temporary.
My word that’s small. Size of a NY fawn.
But Women’s Boobs will.
That explains those huge Russian women in Siberia I guess.
What about rain or snow?
