Do Bears Are Prosperous Animals: Do They Hibernate?

Global warming is the recent and ongoing rise of temperature on a global scale. Over the past century, the Earth's average temperature has risen 1.4°F (Carlowicz, 2010). Global warming is the effect of an excessive amount of greenhouse gases in the atmosphere. Greenhouse gasses trap heat from escaping back into space to keep the Earth from freezing, this is called the Greenhouse Effect. An excessive amount of greenhouse gases in the atmosphere trap too much heat, thus, causing Earth's temperature to rise.

The grizzly sheds the thick part of their coat during the summer. The coat also protects the grizzly bear from insects or any types of bugs. The grizzly bears have a very large home range that they will roam through. The grizzly bear also spend hours of the day walking around, but that is common for grizzly bears. The wear in the temperate rainforest is sunny and sometimes rainy. When the grizzly bear needs to move quickly through their habitat it can be done so at a speed of 30 miles per hour. The mating season for grizzly bears start in mid-May it continues until the middle of July. Grizzly bears can live in the wild up to 30years. They can also die at the age of 25. Grizzly bears can be found in woodlands, forests, alpine meadows and prairies. They prefer to be around streams or rivers. Grizzly bears are mainly solitary, except for mothers and their cubs. Grizzly are known to meet up at a river or a stream. Grizzly bears are also very strong swimmers. Grizzly bears use sound, movement, and smells to communicate with each other. Grizzly bears happen to groan and moan to get each others attention. Grizzly bears also rub their bodies on trees so they scratch their self. Throughout the summer grizzlies build up fat by eating as much

Unfortunately, about twelve bears are killed annually while traveling to hibernation spots for the winter. After the bear comes out of hibernation, they will eat anything for food, because they are so extraordinarily hungry. (animals) The bear's hibernation spot depends on the weather, it can be under tree roots, in a cave, or even in a hollow tree based on how

Hibernation: Hibernation is a sleeping state, which lasts for long periods of time. ANimals like bears, eat lots before entering hibernation so that their body has enough fuel to live. They enter hibernation during winter, because during winter there is no food for them to eat, and if there is it is very scarce.

Black bears are the smallest North American bears however; they are the largest land mammal in New Jersey. Black bears evolved in thick forest and live in mixed hardwood forests, dense swamps and forested wetlands. They naturally like to eat fresh leaves, berries, fruits, nuts, roots, insects, bird eggs and small mammals. Black bears are generally solitary animals, with the exception of a sow and her cubs. They tend to be crepuscular, meaning they are most active shortly before sunrise and again after sunset. Black bears are typically not aggressive and tend to be wary of humans.

“Black bears are not true hibernators” according to Nation Geographic. Black bears have several reasons they may leave their den during the winter months, mainly if they do not have enough food to last the winter, they will leave and search for more. If the weather is warmer like down in Florida and Louisiana, they don’t necessarily have a winter. They will remain in their dens if they give birth, presumably for the safety of the cubs.

The Ursus Arctos otherwise known as the grizzly bear lives in North America around Northern Canada, Alaska, Wyoming, Montana, and Idaho. A grizzly bear lives in the wild and hunts for its food such as fish, deer, elk, or any other animal. They live inside of caves for protection from the weather, they will also live under trees or anything that will provide them shelter. I believe that grizzly’s have evolved into animals that can survive in many climates and environments.

The female bear will stay with her cubs for one and a half to two years. The mothers will teach cubs important life survival skills and then leave them to have another litter of cubs (American Black Bear, 2015). Males will leave hibernation early to search for a mating partner, while females do not. Another way males and females are different is there physical appearance. Male skulls are 10% larger than females (Ballard,

White bears require a variety of physical characteristics to survive in the harsh environment of the Arctic. Large, wide paws with bumps allow them to distribute weight and grip more efficiently. Water resistant fur with a luminescent quality keep the bear warm and dry. Additionally, Sharp and powerful teeth have the ability to penetrate hard flesh. These special features allow not only the ability to thrive in a difficult environment, but also are important for communicating with other species and another bear.

How much do you absolutely perceive about bears? In this article I will educate you all there is to know about bears hibernating, and if they can cure human illnesses. My topics are, Heart, Bones, and muscle illness.

With the ever rising global temperatures, melting ice caps, and constant warnings about global warming, it is no wonder that the animals inhabiting the artic regions around the world are now suffering a decline in their habitat as well as their livelihood. Such is the case with the Polar Bears who may soon be gone in a scant few years.

In conclusion, it took many years for polar bears to adapt perfectly to their new arctic environment. However, they’re facing a new challenge and threat due to the melting of the arctic ice because of global warming. In response, the polar bears will eventually evolved to have thinner fur or the polar bears will be forced to adapt to the increasing temperatures of their habitat and may severely decrease the population. In the future, the cross breeding of polar bear and grizzle bears will help these species survive their changing environment.

Depending on the fossil record and DNA examination, researchers have possessed the capacity to land at a clearer photo of the polar bear's transformative way throughout the centuries. Somewhere in the range of 200,000 years back, when ice sheets secured quite a bit of Eurasia, the Arctic Ocean was totally solidified. It was amid this testing period that cocoa bears started to meander looking for sustenance. Roughly 125,000 years prior a populace of chestnut bears in the most distant north of their range was likely separated from their cocoa bear progenitors, maybe in view of rivalry for nourishment. The populace likely got to be confined by enormous icy masses and, while most passed on in the unforgiving environment, those holds on for a developmental

Winter is coming! Winter being the time of year when migratory birds and animals begin to make their way to warmer locations. These animals doing this of course to increase their survival chances by bettering their surrounding with plenty of food and warmer weather. Do all animals move to these luxurious destinations to vacation over the cold wintery months? No unfortunately, for most of the animals in the northern temperate areas, they stay year-round. Thus, the question arrives of what exactly do these animals do in order to survive in this type of environment annually. Well, the answer to that question is that these animals actually go into a deep sleep or hibernation.

Not all animals migrate during the winter; such as: birds,fish, whales and sea turtles. On the other hand, most mammals, and some reptiles like the tortoise prefer to sleep during the whole winter, which will usually last up to five to seven months. These months vary from animal to animal; this is called hibernation. Ubeda claims in his article that, hibernation is a deep sleep in which an animal's body temperature drops to just above the temperature of the outside world to conserve as much energy as possible (Ubeda). Hibernation by larger animals, such as, the bear or mountain lion usually occurs during the winter in large dens. On the other hand, if the animal is smaller like a squirrel or a rabbit, hibernation will take place in a small hole or a tree. One reason why hibernation occurs is because food is scarce and harder to achieve, so animals need to conserve all their energy. In Grabianowski’s article, he claims that an animal starts hibernation by slowing their heart rate down (which allows their body temperature to drop) (Grabianowski).
