They are scarce because of over hunting and people destroying their habitat. The next Bear, the Andean all branch around the same time between 5 and 8 million years ago. Theory’s say Sun Bears split from Sloth bear first and the Black Bear lineages diverged. These bears are closely related in size and what they eat. The most recent evolution recorded are the Brown Bear and the Polar Bear.
In many areas, the wolves are nearly gone because they were killed by humans. Wolf recovery programs are reintroducing wolves to remote forests and many people such as ranchers are unhappy about these wolves. They say that the wolves will kill their cattle and sheep while others see the reintroduction as important in reestablishing a balance in nature. Dog history is as rich and varied as the dog breeds themselves. Research about their history indicates that all dogs originated from ancestral wolves, but careful breeding has created dozens of distinct breeds that highlight desired characteristics.
Over the last hundred years, hunting and forest destruction have reduced overall tiger populations from hundreds of thousands to perhaps 3,000 to 5,000. Tigers are hunted as trophies and also for body parts that are used in traditional Chinese medicine. All five remaining tiger subspecies are endangered, and many protection programs are in place. Poaching is a reduced—but still very significant—threat to Siberian tigers. Tigers live alone and aggressively scent-mark large territories to keep their rivals away.
The gray wolf also called the timber wolf, is the largest of about 41 wild species within the dog family They range in size from 26" to 38" shoulder height, 39" to 80" in length (tip of nose to end of tail), and vary in weight from 57 to 130 pounds. Their coats may vary in color from grey to brown, from white to jet black. They usually hunt at night and feed primarily on large hoofed mammals such as deer, caribou, elk, and moose, but sometimes eat berries, birds, beaver, fish, and insects. Animals that they kill are usually young, old, or otherwise weaker members of their populations because they are easiest to capture. Most pursuits of prey range in length from 110 yds.
Just prepared. North America is home to three species of bears. But because most of us aren’t likely to head out for a day hike in the Arctic, I’ll skip polar bears and focus instead on grizzlies (also known as brown bears) and black bears. • Grizzly Bears Range: Grizzlies have been eliminated from 98 percent of their native range in the American West and the Great Plains, according to the environmental organization Defenders of Wildlife. They’re now found from Alaska (the population
With all that being said, the cheetah might not be able to surpass its extinction. Cheetahs are listed on the International Union for Conservation of Nature and the US Endangered Species Act, which are list of vulnerable species. There are currently about 12,400 cheetahs living in the wild, and the largest population currently established in Namibia with about 2,500 cheetahs. Why are cheetahs endangered? Many say it’s mainly cause of a drop in prey, loss of habitat, poaching, and high death rates of cheetah cubs.
When they become overpopulated, the whole eco-system can be drastically affected. Native food sources can be depleted very quickly which can result in extinction. For example, the loss of cougars and wolves in much of the U.S has led to many species becoming over populated. Without the whitetail deer being hunted, there would be major crop damage and many more car versus deer accidents. Overpopulation often leads to disease and malnutrition.
They get all the liquids that they need from the animals that they eat. Polar bears are mostly solitary mammals except for female-cub groups, during mating season, and at abundant food sources. Cause In the past polar bears were hunted for their fur and meat. This caused a great decrease in the polar bear’s population. Since then many countries made up laws that helped these creatures from being extinct.
Many things are hindering this species ability to survive. Amur leopards are endangered due to conflict with humans, habitat loss and fragmentation, poaching/illegal trade, inbreeding and vulnerable population size, and a scarcity of prey. Territory loss is one of the main reasons that the Amur leopard is critically endangered. The Amur leopard’s habitat is mostly temperate broadleaf forests and the mountains. Human induced fires are a main threat.
Why is the animal endangered? What are humans doing to affect the sustainability of this species? The Moon Bear is endangered from illegal hunting of the Moon Bear’s body parts, habitat loss from logging & athe main reason being because over Asia thousands & thousands of bears are on bear farms, kept in tiny cages, in order to get bile (a liquid in bears produced by the liver, that helps to digest the bears fat) from the gall bladders. Catheters (a metal tube) are implanted into the bears gall bladder (next to the liver in the abdomen), where the bile is drained up to twice a day. The procedure is very unhygienic & causes many infections where some bears die as a result.
