Do you suppose that due to the seclusion of the Kodiak Bear that genetics may have an affect on their larger size? While 3500 bears on Kodiak is likely enough to prevent the negatives of inbreeding, the gene pool within their limited area is likely much much closer than the Kamchatka version. Combine the food availability and the largest males breeding it would seem to be a much closer genetic preference for larger Bears. That's just my opinion of course.

I agree, that is most likely true yes.

I would also wish that DNA tests would be made to see which brown bear subspecies contain the highest level of Cave bear DNA. I would wager on Kamchatka and Kodiak.  |

King KodiakRegarding the table you shared on Kamchatka bears; they are splitted in two groups: Ursus arctos beringianus and Ursus arctos piscator, that's an outdated classification. These two terms are synonyms for the Kamchatka brown bear today, they are the same subspecies. The author might have referred to different populations on the island.

The Kamkatcha brown bear is the Kodiak bear of the east.

www.theclever.com/15-places-on-earth-that-have-never-been-explored/ On Russia’s eastern peninsula, there is a region with a crazy amount of volcanic activity. It has over 300 volcanoes, one of which has been erupting for over 20 years. Like most places largely unaffected by humans, it has a range of wildlife, including an eclectic range of salmon species and a large brown bear habitat. In fact, it is considered to be the most densely populated brown bear habitat in the world. This region was largely unsettled because it was closed off to Westerners until 1991. It is still only populated by 400,000 people, which is pretty sparse for such a large area.

These Kamkatcha brown bears look like large individuals.

I dont know how reliable this is, but this hunting site mentions that the average weight of the Kamchatka brown bear is 300 kg (661 lbs), sounds pretty reliable considering that the Ussuri brown bear averages 286 kg.
Also, they mentioned this: the youngest age for fully grown should be 9:
Kamchatka bears grow and gain weight all their life span. The age periods they gain most of their weight are 9-12, 25-35, and up to 40 years old. However, age and weight are not always connected. Some species happened to be 35 years old with the weight not more than 200 kilograms.

I would say a great find Kodiak. Quote: Kamchatka brown bear is the largest one among brown bears and one of the biggest terrestrial predator with the average weight 300 kg. ( 661 lbs ). According to some researches, the heaviest registered specie of the adult brown bear in this region was 650 kg.( 1433 lbs ). Yet, the male bears can weigh up to 700 kg ( 1543 lbs ) during the intensive feed season.

Physical Description.Male Kamchatka brown bears can reach a weight of 700 kilograms, and are among the largest bears in the world. Their large physical size is a result of their access to rich food sources like salmon, pine nuts and berries. Maintaining body weight is crucial to survive the long period that bears spend sleeping in their winter dens (up to 6 months on Kamchatka). russia.wcs.org/en-us/Wildlife/Kamchatka-Brown-Bears/Ecology.aspx

More: As for Kamchatka brown bears, they are characterized by an amazing strength; therefore, they are a great danger for people and other animals. Despite their huge size, they have an instant reaction and amazing physical endurance. Brown bears have no rivals in their habitat. Once in a while, a pack of wolves might hunt a bear. Yet, they are able to do it if a bear is under distress. Also, these predators can feed on each other. Kamchatka bears grow and gain weight all their life span. The age periods they gain most of their weight are 9-12, 25-35, and up to 40 years old. However, age and weight are not always connected. Some species happened to be 35 years old with the weight not more than 200 kilograms. hunting-experience.com/kamchatka-the-land-of-bears/ |

Arguably the most popular topic as it relates to brown bears: where do find the heavyweights and just how heavy do they get? The following thread addresses these questions and a lot more as they relate to the largest brown bears in the world. In this regard, there is some reason to believe that in accordance with the hypothesis of (Rausch, R. 1963) the large bears in southern Alaska and British Columbia, there occurs the proliferation of large forms U.arctos on the Kamchatka Peninsula, Sakhalin and Amur region which is also associated with its habitat in these areas are many populations of anadromous Pacific salmon - genus Oncorhynchus. The point, apparently, not only in the overlapping ranges of salmon and large subspecies of brown bear at the present time, but especially of trophic relationships that evolved between the four-legged predators and salmon on the Pacific coast of Beringia in the individual stages of the Late Pleistocene. These coastal bears are of large size and wide skulls that has been associated with use of spawning Pacific salmon (Onchorhynchus spp.) by Kurten [1973]. More specifically, bears with the relatively widest zygomatic arch, inhabiting Kamchatka and Kodiak Island, share their ranges with spawning grounds of the two largest species of salmon (sockeye [O. Nerka] and Chinook [O. Tshawytscha]). There is little doubt that the first brown bears inhabiting coastal regions of the Okhotsk and Bering Seas during the Wisconsin also had access to anadromous salmon (Cherniavskii & Krechmar, 2001).

It is interesting that brown bears live on the far end of north east and west.

Brown Bear populations in Russia: www.bearconservation.org.uk/eurasian-brown-bear/ Eurasian brown bear - Range: Found in northern Eurasia. There are believed to be over 100,000 brown bears in Russia, about 36,000 of which are in in European Russia. Elsewhere in Europe there are a total of around 17,000 brown bears, around 5,000 to 6,000 of these being found in the Carpathian Mountains area of Romania, the largest single population outside Russia. domainofthebears.proboards.com/thread/270/kamchatka-brown-bear?page=3 Kamchatka brown bears - Population estimates for the entire Kamchatka peninsula range from 10,000-14,000 bears in an area about the size of California. www.bearconservation.org.uk/east-siberian-brown-bear/ East Siberian brown bear - Around 5,000 bears in the Altai Mountains and over 16,000 in the East Siberian Taiga.

Kamchatka bear: www.expresstorussia.com/experience-russia/types-of-russian-bear.html The Kamchatka Peninsula is about as far east as you can get in Russia. This land of windswept tundra, rising volcanoes and frozen beaches is closer to Alaska than to Moscow. The bears over here too are closer to their gargantuan Grizzly kin across the sea than to the comparatively cuddly Brown Bears in Europe. Side by side, the Kamchatka bear is more than 1,5 times as heavy as a Eurasian Brown bear. Ice-cold streams brimming with a unique type of wild, blood-red salmon mean that Kamchatka bears can reach up to 650kg, making them by far the largest brown bear in Eurasia. Only the Kodiak bear in Alaska exceeds the Kamchatka bear in weight.  |
