Domain Introduction

[brobear]

The topic here at "Domain of the Bears" is bears - family Ursidae. Our aim is to discuss bears with other bear enthusiasts. We wish to view the bears from the perspective of hunters, naturalists, scientists, grizzled old mountain men, photographers, hikers and campers, historians, and anyone else that I might have missed. We will take a close look at all eight species of living bears as well as bears and bear relatives which are now extinct. 
For those who wish to discuss other animals such as lions, tigers, sharks, crocodiles, dinosaurs, etc.... well, I'm afraid that you are at the wrong place. Other animals will be discussed only within some of our bear topics. I sincerely hope that we draw in some good, honest, mature posters who can share some quality information with us here at the Domain of the Bears. 
We request that, before starting any new topics, please search the proper section thoroughly. Chances are that the topic you have in mind is already here. Such topics are all bear related and of animals that do or have in the past shared their environment. We do not wish to turn this site into a three-ring-circus of outrageous animal face-off topics such as lion versus tiger. Such topics will be immediately deleted. If you feel a need for such topics, then by all means open your own blog site.

The Eight (8) Bear Species of the World

1 -North American Black Bear – Ursus Americanus – colour – black, bluish-black, brown, white (Kermode or Spirit bear). The North American Black Bear is the most common bear in North America ranging from the State of Florida north, into Canada and north to Alaska. The black and brown colour phase of the black bear is common. The white colour phase is more rare occuring in north western British Columbia, Canada. The black bear is omnivorous. Their diet is mostly vegetable matter. Males reach full size at about 8 years of age. Females mate and produce cubs at 5 to 7 years of age, 8 years and older in the boreal forest regions(Ontario). Males weigh up to 280kg(600 pounds), occasionally much more. Black bears live up to 25 years in the wild. Older bears have been documented, however the majority of bears never reach old age due to human activity (hunting).

2-Brown Bear – Ursus Arctos – Several subspecies. The Brown Bear can be found in Alaska, western Canada,and parts of Washington, Montana and Wyoming. Small individual populations are scattered throughout parts of Europe and Asia. Russia has a healthy population of brown bears currently. Brown bears range in colour from almost black, brown to very light brown or blonde. Size varies greatly depending on geographic location and general food availability. The largest bears, the “Big Browns” exist along the coast of Alaska and Russia growing to very large sizes rivaling that of the Polar Bear. The interior bears of the North American Rocky Mountains (Grizzly Bear) and the mountains of Europe tend to be much smaller. The really big bears (1500pounds/700kg and bigger) are now very rare.

3-Polar Bear – Ursus Maritimus Polar bears are among the largest bears in the world. Adult males may reach 800 kilograms (kg) or 1760 pounds (lbs). In Ontario, the largest male bear recorded from “live capture” research studies weighed 654 kg (1439 lbs). The average weight of male polar bears in Ontario is about 500 kg (1100 lbs). Adult female bears are smaller and average around 300 kg (660 lbs); their peak weights do not usually exceed 400 kg (880 lbs).

4-Asiatic black bear, Himalayan black bear, moon bear –Ursus thibetanus Asiatic black bears have long black fur with a distinct white patch on the chest that is often crescent-shaped. The fur around the shoulders and throat is particularly long, and their ears are relatively large. Asiatic black bears live in eastern Asia, including Afghanistan, Bangladesh, Bhutan, Cambodia, China, India, Islamic Republic of Iran, Japan, Democratic People’s Republic of Korea, Lao People’s Democratic Republic, Malaysia, Mongolia, Myanmar, Nepal, Pakistan, Russian Federation, Taiwan and Vietnam. Asiatic black bears are more carnivorous than their American counterparts, although only a small part of their diet is made up of meat. This includes small mammals, birds, fish, molluscs and carcasses. They also feed on grasses, fruits, berries, seeds, insects and honey. In autumn they fatten up for the winter by feeding on nuts. In northern climates they hibernate. In southern climates they do not hibernate.

5-Andean Bear or Spectacled Bear – Tremarctos ornatus Most scientists refer to spectacled bears as Andean bears (they are found only in the Andes mountains in South America). The bears are an endangered species, listed as Vulnerable, and it is illegal to kill them. The Andean bear is the last remaining short-faced bear (subfamily Tremarctinae) and the closest living relative to the Florida spectacled bear and short-faced bears of the Middle Pleistocene to Late Pleistocene age. Spectacled bears are the only surviving species of bear native to South America, and the only surviving member of the subfamily Tremarctinae. The Spectacled Bear is technically the largest land carnivore on that continent, although as little as 5% of its diet is composed of meat. South America’s largest obligate carnivore is the jaguar. Among South America’s extant, native land animals, only the Baird’s and South American Tapirs are heavier than this species. The Spectacled bear is a mid-sized species of bear. Overall its fur is blackish in color, though bears may vary from jet black to dark brown and to even a reddish hue. The species typically has distinctive beige-coloured marking across its face and upper chest, though not all Spectacled bears have “spectacle” markings. The pattern and extent of pale markings are slightly different on each individual bear and bears can be readily distinguished by this. Males are a third larger than females in dimensions and sometimes twice their weight. Males can weigh 100 – 200 kilograms (220 – 440 lb), and females 35 –82 kilograms (77 – 181 lb). Length can range from 120 to 200 cm (47–79 in), with a tail length of a mere 7 cm (2.8 in), and shoulder height from 60 to 90 cm (24–30 in). Compared to other living bears, this species has a more rounded face with a relatively short and broad snout. In some extinct species of the Tremarctinae subfamily, this facial structure has been thought to be an adaptation to a largely carnivorous diet, despite the modern Spectacled bears’ herbivorous dietary preferences.

6-Panda Bear – Ailuropoda melanoleuca Length: 5 ft (1.5m) (with a 6 inch(.2m)tail). Weight: Around 250 lbs (113 kg) (males); around 220 lbs (100 kg) (females). The giant panda is a rare, endangered and elusive bear. Science used to believe that the giant panda was a member of the raccoon family. With DNA analyses science proved itself wrong. The giant panda and the red panda are not related. Giant pandas are famous for their love of bamboo, a diet so nutritionally poor that the pandas have to consume up to 20kg each day. The extra digit on the panda’s hand helps them to tear the bamboo and their gut is covered with a thick layer of mucus to protect against splinters. Habitat loss is the greatest cause of the giant panda’s decline, and today their range is restricted to six separate mountain ranges in western China. A giant panda is born pink, hairless, blind and 1/900th the size of its mother. Unlike other bears, giant pandas do not hibernate. In the winter, they move to lower elevations to keep warm, while traveling to higher elevations in the summer to stay cool. They can be active at any time of the day or night.

7 -Sloth bear–Melursus (Ursus) ursinus -Two subspecies: Sri Lankan Sloth Bear and Indian Sloth Bear. Body length: 140-190cm, Weight: male: 80-140kg, female: 55-95kg. These shaggy-haired bears can be heard sucking up termites a long distance away. Sloth bears are stocky with long, shaggy, black hair and a white U- or Y-shaped marking on the chest. They have large lips, a long tongue, a pale muzzle and well-developed hook-like claws that enable them to climb trees and dig for termites. Sloth bears live in Sri Lanka, India, Bhutan, Nepal and Bangladesh. Sloth bears are nocturnal and occupy home ranges that they seem happy to share with other sloth bears. Male sloth bears have an average range of 13 square km. This is much smaller than most other bears, probably due to the fact that they do not suffer from seasonal fluctuations of food supply (ants and termites are available all year round). The constant availability of ants and termites also mean that they do not need to undergo a winter sleep.

8-Sun Bear – Ursus malayanus –Body length: 120-150cm, Weight: female 27-50kg, male 27-65kg. They are the smallest species of bear. Sun bears have short black/dark brown water-repellent fur, with a yellow crescent on their chest. They have strong paws with naked soles and long sickle-shaped claws. They have flexible snouts and very long tongues, which are an adaptation for extracting termites from nests. Relatively(to their size), they have the largest canines of all the bear species. Canine teeth are specialised for tearing meat, but sun bears are not particularly carnivorous. They may use their sharp canines as weapons or as tools for tearing at trees to get at insects. Sun bears live in south east Asia: Brunei Darussalam, Cambodia, China, India, Indonesia, Lao Peoples Democratic Republic, Malaysia, Myanmar, Thailand and Vietnam.

Besides seeking all available information on the eight living bear species, we also delve into the world of extinct and prehistoric bears. We even venture into the realms of legends and mythology. On a darker note, we participate in animal face-off scenarios. In this and in all topics, our mission is the truth. In the face-off topics, our goal is not to win, but to give an open and honest assessment. We must not overplay the bear's true nature and capabilities. Let's not lose our credibility.

I feel the need to suggest; don't post merely to "build a bigger bear" - Quality before Quantity please.

[theundertaker45]

Brobear nailed it; think before you write please.

[OldGreenGrolar]

I think most of here are quality posters. Not many posters beat us when it comes to bears.

[King Kodiak]

I just got to cave bear baby, yeah!.

No worries. May I know what colour are the stars for the polar bear rank?

[theundertaker45]

@thegreenartos

Five seafoam stars represent the polar bear rank.

[OldGreenGrolar]

Just a suggestion theundertaker45 , I personally believe that the polar bear rank should come before the Kodiak bear or cave bear as the Kodiak bear is not much lighter.

Cave bear are heavier than most polar bears except the yellowish white bears from Foxe Basin.

I think the polar bear rank at 10000 post should be replaced by the Steppe brown bear (Ursus Maritimus Tyrannus looks more like a brown bear) but again it’s my suggestion. You are the boss here 😊.

[King Kodiak]

Well actually the Steppe brown bear is (Ursus arctos Priscus), the Pleistocene European brown bear.

domainofthebears.proboards.com/thread/905/pleistocene-steppe-bear?page=1

Tyrannus is most likely a brown bear, but we dont know if its Priscus or not.

Good suggestion by the way.

[theundertaker45]

I am not at home this weekend, however, I'll adjust it the upcoming week. 😁

[theundertaker45]

As requested, I will now make the following changes regarding the rank system:

Kodiak Bear - 6000 Posts
Polar Bear - 7000 Posts
Tyrant Polar Bear - 8000 Posts
Cave Bear - 9000 Posts
North American short-faced Bear - 10000 Posts

The reason for this division:

- Polar bears have to be considered the largest bears alive under ideal circumstances; they are generally slightly larger than Kodiak bears.
- The tyrant polar bear was estimated to be just slighty larger than our modern polar bear.
- Cave bears could reach the size of tyrant polar bears, however, they were smaller in frame and more stocky.
- North American short-faced bears most likely averaged highest out of the four.

Looks good to me 'Taker.
