Hibernation

The Grizzly Bear Vincent Bauer Ecology March 3, 2017 Mr. Kopanke The Grizzly Bear, also known as the North American brown bear, or even more rarely as the Silvertip Bear is one of the largest land animals on the planet. It stands about 1.2 meters (4 feet) tall to the shoulder, and 1.8-2.4 meters (6-8 feet) long. When standing, it can stand up to 3.6 meters (12 feet) high. They weigh anywhere from 136 to 362 kilograms (300-800 pounds) , but the largest grizzly bear ever shot by a hunter…

go into resting periods in order to preserve energy. Gut microbes will change when squirrels are in hibernation because their dietary intake will switch from active to inactive. This means that they will not consume food during their hibernation, including interbout arousals or periods of time where conditions return the squirrel’s active state. Microbes in hamsters do not change during hibernation because during their interbout arousals, they do in fact consume food rather than the lipid-based…

There are too many species in the world to even try to count, and overtime all of them have had to adapt and evolve to survive in their habitats. Some species have changed in color over time to be able to blend better with their environment for survival. While other species have grown fins, some have grown legs, some have even changed to be both water and land, and others wings. One of the many animals that has evolved and grown wings is the bat, although bat wings are different because they…

What is CCD? CCD stands for colony collapse disorder, which is a sudden population loss in worker bees. This loss leaves the queen alone with a few nurse bees to take care of her and the few remaining young bees. When a colony is affected by CCD, there are very few dead bees near the colony. What causes CCD? Varroa mites are one of the bigger problems. Varroa mites are parasites that hitch a ride on a bee, and end up in the hive. Once they are in the hive they lay eggs and any bacteria or…

The Evolution of Polar Bears Laysa De La Torre Polar bears have a very interesting history as they are evolved from brown bears. It is very weird how they don’t hibernate but interesting to hear what happens when they don’t hibernate. Polar bears are actually very interesting even if you may not like them, you will soon be interested after reading this. Polar bears hair is white because, the air spaces in…

because they have less fat than bigger bats do, so it will be faster for them to waste their fat reserves (Dechaine & Johnson, 2014). Lastly, I hypothesized that the White-nose syndrome causes bats to increase their frequency of arousals during hibernation. I think this hypothesis would be correct because, without White-nose syndrome, the bat would hibernate through the winter time without needing to wake up often (Warnecke et al.,…

Black bears are the most abundant and adaptable bear in its family and therefore are widely distributed (Youth 1999). They are the smallest on the North American continent though its species Ursus americanus has several subspecies in B.C. (Blood, Black Bears in British Columbia 2001). Most bears are black, hence the name black bear, however, they can have a variety of different shades of brown coat and sometimes even white (Blood, Black Bears in British Columbia 2001). These bears become…

humans and animals. A few habits that animals and humans show a similarity in, is migration, natural adaptation, and hibernation. As people may know, humans don’t hibernate, but just like some animals conceal themselves in the cold, some humans choose to stay inside more in the winter time. When the weather changes and becomes warm again, those animals come out of hibernation (Aristotle, 125). Migration is another habit that animals and humans show similarities in. Some animals migrate far and…

Some experts believe that in the home to enter turtles, snakes and other animals in hibernation should not, others believe that sleep is required for them.Reptiles - cold-blooded animals. They hibernate when the ambient temperature is too high or too low in order to maintain their vital functions of the body.At home, at a stable temperature…

deep sleep allows the grizzlies to conserve energy for all of the months in hibernation. A Grizzly Bear can eat up to 90 pounds of food a day to build up fat. That can add up to 2.2 pounds a day. Pregnant Grizzly Bears while sleeping, can give birth to a baby cub. Grizzly Bears could survive extremely well in Minnesota. They have long claws that are the size of human fingers, they have strong backs to dig holes for hibernation and they can run up to 35 mph. They would be very fit to live in…
