The post 1,931 (from @peter) and 1,934 (from me) in the page 129 of this topic, present good information about the size change in the brown bears from the Russian Far East.

Bear weights are always problematic if there is only a chart with a few specimens and no details about age range and as you also said earlier, what time of year weighings have been made. It is quite difficult to make too big conclusion with data where is mentioned, that 10 specimens for instance and then mentioned only "adult". There is for instance open question, that does adult mean there a bear at age when starting breeding, which is about 5 years, or does it mean a bear, which can be counted as full grown, which means about 9-10 years old. When combining that to big changes in weight from spring to autumn, these details should be involved to these charts so, that readers could figure out, that do those numbers have value if comparing for instance bear sizes in 1970´s and bear sizes today. With many other animals weight is much more stabile during a year if able to get food regularly.

That is the reason why I think, that in those charts is maybe too little information to make big conclusions. Reply
