Recommended: Polar bears climate change effects

Polar Bears live in the Arctic. In the winter, the temperatures range from -39°F to 30°F and in the summer, it ranges from 14-50°F. The arctic gets about 15-25 cm of precipitation throughout the entire year. A Polar Bear's niche is a predator, meaning they hunt for food. In a food web, there are listed as a tertiary consumer, which is the highest level on the food web. Polar Bears are a keystone species because the Arctic habitat is currently endangered. Polar Bears mostly eat animals such as beluga whales, walruses, and they rarely eat any type of vegetation. Polar bears have many symbiotic relationships with other animals. Polar bears have a symbiotic relationship with the earthworm, Trichinella. The relationship is specified

    Hey, I didn’t see you there, how are you?I'm just wondering whether or not a big ol' grizzly bear is going to come charging at me at any point in my life, but seeing as grizzly bears are endangered that probably won't happen. In the past, there were thought to be around 50,000 grizzly bears in North America, nowadays they are growing sparse there are estimated to be only around 1800, now not even a 20th of the population in the past. Most of these grizzlies are located in Yellowstone National Park and Alaska, but they can also be found in Wyoming, Colorado, Idaho and Montana. Some are thought to be in Washington.

    The Arctic Tundra is the biome where the Polar bear, Ursus maritimus, or the sea bear live. The climate over there is in the Arctic and is Earth's coldest, where it is treeless and covered with piles of snow and ice for the whole year until summer when it brings wildflowers. On the top of the mountain it is colder, windy, and rainfall is scant.

    Bears can live anywhere but Grizzly bears live in subalpine meadows and dense forests. When grizzly bears hibernate they usually live in caves. A sloth of bears is usually a mom and the cubs. The mom bear is called a sow, the dad bear doesn't have a name because they are never with the family and the babies are called cubs. There is usually a dearth amount of cubs in a family. The families are always together and not with a different family. All bear look different but I'm not talking about the other bears I am talking about grizzly bears. Grizzly bears are usually just the color brown and not really anything different. Grizzlys need big paws to get around and travel. Bears have small black eyes. Their eyes are small because they don't need very good eyesight because they have such good sniffers. Usually the weight of a cub is about 4- 10 pounds when they are born but when they are adults they weigh 175- 500 pounds.

    grizzly bears prefered habitat is deserted rivers, wild mountains, and thick and dense forest. Grizzly bears are majestic symbols of the wild. Bears live in and use a variety of habitat types, playing important roles in each one. This makes them an “umbrella species,” meaning that when we protect them and their habitat we also protect many species. Grizzly bears can also help ecosystems by distributing seeds and nutrients through their scat, and occasionally regulating ungulate populations.

  • Tardigrades

    The “water bear” is a common name for a group of a little over 100 genera of protozoans grouped under the Phylum Tardigrada and is a relative of the Phylum Arthropoda. The phylum Tardigrada contains over 1000 species, and is grouped into three classes. There are two main classes the Heterotarigrada ad the Eutardigrada. The last is the Mesotardigrada and contains only one species, that was discovered in a sulfur spring in Japan 1937, and has not been seen since. “Water bears” are, as with most species, separated into groups by characteristics and more recently molecular genetic methods. The Heterotarigrada are known mainly for their hair like tufts on appendages and hard-undivided flattened scales. The Eutardigrada are known as “naked tardigrades” because they lack the hard scales or have several separate plates. Tardigrades are then divide further into orders by comparing groups for cuticle appearance, feeding tube, claws, and other defining features (Michalczyk, 2014).

    The animal that I chose to research was the Honey Badger. The scientific name of the Honey Badger is Mellivora capensis and it is in the animal class Mammalia. An interesting fact about the Honey Badger would be that they have a very powerful bite. Their bite is so strong, that Honey Badgers can chomp down with enough force to break the shell of a tortoise. The Honey Badger is a fearless, and very interesting animal.

  • Polar Bears: The Evolution Of The Polar Bear

    Out of an Ice Age emerged one of our most majestic creatures in the world, the polar bear. From its brown bear ancestry, the predator evolved to be a master of a harsh and unwelcoming ice kingdom. Intelligent, adaptable and fierce, the polar bear learned how to survive in a place that offers few comforts to any creature. But now that very environment is in flux. And so is the polar bear’s fate (Nature).

  • Polar Bears: The Speed Of Climate Change

    Polar bears don't just live on ice, they use the ice as an advantage to catch prey such as seals. Polar bears have adapted to living on ice and being able to withstand the cold weather. Now that the climate is changing at a fast pace, polar bears are losing their land because its melting, leaving them with no place to walk, sleep and taking away their way of hunting prey. (polar bears international, 2015) This is all happening so fast that there is no way polar bears will be able to adapt to the new environments, causing extinction. The arctic is warming twice as fast as the rest of the world is due to the build up of greenhouse gases in the atmosphere, making it a problem happening very rapidly. (Bagley, 2015) Temperatures in the Arctic region have risen 7 degrees Fahrenheit over the last half century. (Bagley, 2015) Population among polar bears has decreased up to 40% in some areas. (Bagley, 2015) With the climate getting warmer, ice is melting earlier every spring, and takes longer to freeze every winter which is disrupting the feeding and breeding cycles of many different arctic species. (Bagley, 2015) Polar bears have adapted ways to survive in the cold harsh arctic environment including having the ability to cool down their outer skin to keep their vital organs warm when they are submerged in cold water. Though this may help the delay of hypothermia as they have to swim greater distances from ice shelf to ice shelf, that doesn't mean polar bears can swim forever. (Bagley, 2015) One bear that a scientist studied swam 500 miles over nine days, but lost 22% of her body weight, and lost her cub.(Bagley, 2015) Many different scientists have been studying the behaviour of the polar bear to see if it could adapt in any way to survive. Eight U.S scientists made a hypothesis consisting that polar bears could lower their metabolic rates enough to survive as food

    The habitat is also made up of trees with nuts and bushes with berries. Black Bears are omnivores so they eat these along with other small animals. They are opportunist when it comes to food. Mostly bears eat vegetation during the spring but they will eat mainly anything they encounter. During the summer the bears eat salmon out of the rivers if they can catch it. If they can’t catch any they mainly survive off of berries, mainly blueberries, ants, grubs, and other insects. In the fall their diet starts to shift and they start to save up food for winter. They are also known to eat newborn moose calves during the winter when food is scarce.

    One way that the environment impacts the animals is that the animals such as bears adapt and store their energy in the winter. This is also known as hibernating. “Animals in the mountains have also adapted to save energy during the harsh winter months.” (Cassandra Maier, Adaptations of plants and animals to mountains) When animals hibernate, they are less active during the winter, and they just sleep for most of the day. Other animals such as the goat and deer do not hibernate during the winter,

  • The Arctic Region: Climate And Climate Change

    1676 Words  | 4 Pages

    The Arctic region is home to a variety of valuable animals and plants, including polar bear, seal, and so on. The ecosystem of the Arctic region is fragile because these animals are evolved to live in extreme conditions. With the climate change, many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of polar bears. Polar bears mainly feed on seals that indwell icy land. The melting ice reduces the number of seals and food intake of polar bears. In addition, polar bears are used to living in ice caves. The rising temperature causes the collapse of ice caves, which can kill baby bears. The climate change is negatively affecting the biodiversity in the region and will definitely harm the ecosystem

    Polar bears prefer to live in extremely cold artic climates. They live only in the Northern Hemisphere, on the arctic ice cap, and they spend most of their time on coastal areas. Polar bears are widely spread in Canada, extending from the northern arctic islands south to the Hudson Bay area. They are also found in Greenland, on islands off the shore of Norway, on the northern coast of the former Soviet Union, and on the northern and northwestern coasts of Alaska in the United States.
