Do bears actually hibernate? This has been a debatable topic among scientists for a while. There’s multiple opinions for both sides. Some think bears kind of hibernate, some think they don’t, some think they do. The one thing that is making many scientists say that bears don’t hibernate is, bears don’t go into complete deep sleep, they go into torpor where they’re not completely in a deep sleep. It is conclusive to me that bears do hibernate. The bear's body during its hibernation does basically everything every other animal does during hibernation. As said in Article One, “...they will hibernate for 4-6 months. ...they do stop eating, drinking, and going to the bathroom. ...heart rate drops to between 5 bpm and 25 bpm during hibernation.” Some scientists even consider bears to be ‘super hibernators’. “Many scientists now consider bears to be super hibernators. Due to the highly insulative pelts of bears and their lower surface area to mass ratio than smaller hibernators,...”(Article 2). There is definitive evidence to claim that bears do hibernate. …show more content…
Although there is inconsistencies in the bear's body temperature the bear's body temperature is still changing. As seen in The Graph you can obviously see the body temperature going down during the winter (January-March) , when they're hibernating, and back up in the spring (April - `June). For the differences, for example - bears aren’t in a deep sleep. Although they aren’t in a deep sleep like most animals, bears sometimes wake up during hibernation to get a drink if they are dehydrated. So, they wake up because they have to if they don’t want to die of dehydration (Video) . Animals are different on the ways they hibernate or how they
Kermode bears are important for many reasons. The idea of the Kermode bear started with Frances Kermode of the royal British army the bear was named after him because many people thought he was very important. Sometimes these bears can help states attract tourist which helps the state raise money to save the bear’s habitats and the bears themselves from being endangered. These bears are important to people in so many different ways like the bears help hunters in hunting season, they also help give people the meat and bones they need they need to survive and to help make a profit (Local Distilleries’ Fight for Spirit Bears). The Kermode bears are also called the spirit bear because of their white ghostly look which makes them important to some
WOW that is a lot of bears . Kermode bears are the rarest bears. They aren’t seen much by humans. About 20 percent is Kermode bears the rest are black bears. Kermode bears are found in Canada Second, Kermode bears are not polar bears or albinos.
The berries that the bears snack on vanishes. This means that for bears they need to get fat and food before winter so then they will be ready to hibernate for the long winter season. In conclusion, This is why particularly in Alaska, bears need to stock up on food before winter comes because, need to stock up on food before winter comes because when winter hits food goes away, the weight they gain during summer and fall helps them
Ironically, most black bears are not black, but instead are mostly brown, blond, and sometimes reddish brown. Average adult males weight about 115 kilograms and females about 70 kilograms, thought the largest recorded black bear weighed 312 kilogams. Their diet mainly consists of grasses and berries, and acorns during the fall. Black bears consume about 20,000 calories per day, which is equivalent to a person eating 40 McDonald’s Big Mac sandwiches. A fun fact about Yosemite black bears is that their diet has drastically changed because they have become accustomed to eating human food.
Attention Getter] Did you know that according to the National Park Service, in the mid 1970s the Greater Yellowstone region only inhabited about 136 grizzly bears (United States)? A. The Federal Government quickly protected them under the Endangered Species Act, and that is still in force today.
Do dreams have an evolutionary function? In this essay I will discuss Flanagan’s reasons for believing consciousness is an adaptation, I also will discuss why sleep is an adaptation and his stance on dreams being spandrels. And I will end with my opinion on why dreams may or may not be significant based on Flanagan’s theory and the treat simulation theory. I will also discuss the reasons why or why not dreams may have an evolutionary function.
Sloths usually only go the forest floor to defecate, this makes them very vulnerable but when in the trees their color, slow movement and the algae on them acts as camouflages. A sloth’s fur is specialized to grow in the away from the sloth’ body to protect it from the weather when the the sloth is upside down and some of the sloth’s fur have tiny cracks that can collect water .Sloths are folivores, they mainly eat leaves and plant material , some two toed sloth sometimes will eat insects and other small animals. Since sloths mainly eat leaves, it does not give them enough nutrients they need so they have specialized chambered stomachs to slowly digest their food. Sloths also have very low metabolic rates and they have low body temperatures. Researchers have found out that sloths in the wild actually sleep about 10 hours a day and don’t sleep for fifteen or more hours like captive
One of the main reasons polar bears are going extinct is because they aren’t getting the right amount of food they need to survive. Seals, the main food source for the polar bears, are animals that depend largely on the algae that grows on the ice of the Arctic. With the ice content slowly depleting, there isn’t enough seals to sustain the polar bear population. One of the
Climate change, specifically warmer temperatures, has extensively altered these habitats by reducing sea ice extent, thus affecting polar bears since they use it as a platform to travel, hunt, and rest. Changes in the timing of sea ice formation and break up limits the amount of time bears can feed off of seals during late and early summer, hence limiting the amount of fat they are able to store for later seasons. Lower rates of food intake and storage correlates to low reproductive rates, and since females do not have sufficient fat and mass required for successful parturition, they abstain from
