Though, the faster we develop, the faster we seem to drift apart. A quote by Ursus Wehrli offers us a bit of insight on how to deal with the issue, he says, “I like to turn things upside down, to watch pictures and situations form another perspective.” Implementing Wehrli’s words to finding the root of generational divides, leads
Sex- Based Migration in Black Bears (Ursus americanus) Introduction: Ursus americanus, the American black bear is the most common of the world’s bear species, about up to twelve times more abundant than grizzly or brown bears. They usually occupy forested areas but their habitats are highly variable— from the Louisiana Bayou to the Labrador Tundra, and the Northwestern rain forests in between. (Wilson & Ruff, 1999) American black bears are hunted legally seasonally due to their widespread population
The Florida Black Bear The Florida Black Bear (Ursus americanus floridanus) is a subspecies of the American Black Bear which ranges throughout the state of Florida as well as other surrounding southern states. This large mammal is known for its black fur and its inhabitation in forested areas such as Big Cypress National Preserve. History In 1896, naturalist C. Hart Merriam first scientifically classified the American black bear (Ursus americanus) in Florida. He thought that the large mammal’s
Habitat 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. Physical
Grizzly Bears in North America Introduction The Grizzly bear (Ursus arctos) has long been considered to be the symbol of the wild. They are beautiful, powerful and at the same time vulnerable animals. They are known to survive in remote areas not inhabited by humans. The Grizzly was once able to occupy most of the land from northern Mexico to Alaska and most places in between. With a disappearing natural habitat and one of the lowest reproduction rate of any mammal in North America the Grizzly
surfaces. * Polar bears do not hibernate. Females will, however, dig dens in the snow and give birth to their cubs in the winter. The den provides insulation and protection until the sow and her cubs emerge. * The scientific name for polar bear is Ursus maritimus which means sea bear in Latin. They were first identified by Constantine J. Phipps in 1774. Different sources express different theories on the origins of polar bears. Fossil evidence lead researchers to believe that polar bears may have
Polar bears are big, white bears (sometimes darker fur) that live in very cold regions like around the artic poles. There are 21,000 to 28,000 Polar bears alive that are known. Polar bears swim in water and are carnivores, they eat fish . Polar bears feed mainly on ringed seals and bearded seals. Depending upon their location, they also eat harp and hooded seals and eat carcasses of beluga whales, walruses, narwhals, and Bowhead whales. A polar bears' stomach can hold up to 15% to 20% of its
The Effects of Habitat Loss due to Climate Change on Polar Bears (Ursus maritimus) The EPA describes climate change as any significant change in the measures of climate lasting for an extended period of time (Climate Change: Basic Information). The concept of climate change is one too familiar to one of the top artic predators, the polar bear (Ursus maririmus). Many people are aware that due to climate change, polar bears are experiencing extreme habitat loss in the form of melting ice sheets in
SPECIES- Ursus Maritimus, Polar Bear, lord of the Arctic. Lives in an area of five million square miles of snow and ice. From Siberia to Alaska and across Canada, Greenland and the Islands north of Norway, he is the master of all living things except man. It lives in the brutal cold, ice, and snow. The temperature can plunge down frequently to -40 degrees and sometimes even lower but that does not bother the polar bear because of its color-less skin and layer of insulation fat. Its range extending
causing malnutrition, poor body condition (Fig. 2), and lower rates of reproduction and survival (p. 5-6). This has resulted in a 22% reduction in population size between 1987 and 2004 (p. 6). In Conservation and management of Canada’s polar bears (Ursus maritimus) in a changing Arctic, Peacock, Derocher, Thiemann, and Stirling (2011) state that Canada has a responsibility for the conservation of polar bears – the decline in their population is not acceptable, and Canadians must be active in protecting
pulmonary lesions, cysts on the adrenal glands, reproductive impairment, and damage to the immune system. Similar deleterious health risks are observed in the Northern and Southern Resident killer whales (Orcinus orca) and the Arctic polar bears (Ursus

Arctic Ocean and the connected frozen seas are home to the largest and most predatory of the bear family. Every bear alive today evolved 22 million years ago from a common ancestor known as the Ursavus of Asia. Polar bears (Ursus maritimus) came from a group of brown bears (Ursus arctos) over 200,000 years ago, which became isolated from the other brown ... ... middle of paper ... ... phytoplankton to fish, the sea ice is an integral part of the Arctic marine ecosystem” (Derocher, 2014).

In China, wild Asiatic black bears (Ursus thibetanus) are protected as endangered (Raloff). There are caged endangered bears are in Korea also. There are another 1,800 bears are caged in South Korea, but they aren't milked for bile. Instead, when they turn 10 years old, they're killed and
Climate Change and Species Range Introduction The title of “Climate Change and Species Range”, gave me the opportunity to explore a vast array of information. It takes into account the broad and controversial topic of climate change; in general terms, the fluctuations of climatic statistical properties over a period ranging from decades to millions of years, no matter the cause (http://nsidc.org/arcticmet/glossary/climate_change.htm, n.d.). Furthermore the specific effect of the ever changing climate

Have you ever sat down and wondered where the heck did we come from? Well if you did this is the paper for you. In this paper the amazing Darshan Aidasani will be explaining everything about evolution, so sit down, relax, and get a bowl of popcorn because this is going to be interesting. What is evolution? Evolution is the process that all living things developed from primitive organisms over billions of years ago. Up to this day know one knows exactly how evolution occurs, but there are many theories
Phylogenetic trees allow us to organize all of life onto a single tree based on a common feature that all of life shares, to understand how things are related. We can also create specialized trees that map the evolutionary history of a specific species, such as mammals or reptiles. There are three features of a phylogenetic tree that must be understood: first, a phylogenetic tree depicts the common ancestry of the species that we are studying, whether it be all of life or just mammals. Second, there
Walls of innocents. For centuries humans have survived thanks to the ability we have to adapt. One of this amazing activities that helped us is hunting. Unfortunately as we have changed throughout time, hunting has been degenerated into what’s called Trophy hunting. Have you ever heard this phrase before? Well if you haven’t, trophy hunting is when people kill any kind of animal, simply for keeping their bodies as a souvenir for the brutal and ferocious action they’ve just committed. Some may say
Yellowstone National Park Yellowstone National Park is one of the largest and oldest national parks in American history. Yellowstone was the first park to be protected by private investment on March 1, 1872, and the first to be put under the jurisdiction of the National Park Service in 1918, no doubt due to its unique and inspiring landscape and geothermal features. In fact, Yellowstone National Park is home to half of the world’s total hydrothermal features. These awesome attractions draw
