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 long skull and highly arched nasal bones differentiated it from black bears in other areas. So Merriam classified it as a subspecies, (Ursus floridanus), which he called the “Everglades Bear”. Around 1960, the status of the bears was revised to the

Their extrusive canine teeth are used for their meaty diet. When black bears walk, their entire foot hits the ground with their plantigrade feet, each paw having five short, curved digits, with non retractable claws. The distinctive manner of the black bear is pacing, meaning the hind foot is placed somewhat in front of the track of the forefoot. Its eyes are small and its ears are round and elevated. The color of the Florida black bear’s coat is persistently black. However, the summer molt of outer hair sometimes creates a brownish appearance. Only about 1/3 of them have a white chest blaze.
Florida black bear adult males weigh 251-352 lbs. and adult females weigh 132-180 kgs. Though, depending on a high calorie diet, they can grow even larger. The largest male Florida black bear recorded was 624lbs. killed in southwest Florida and the largest female was 400lbs. killed in northwest Florida.
Distribution
Back in the day, the Florida black bear inhabited most of Florida, besides the Keys, as well as the southern parts of Georgia and Alabama. Two hundred years of deforestation and hunting later, they attained an all time low point in population and distribution by the 70s. Fortunately, throughout time much of the bear’s habitat has been restored due to consecutive regrowth of forests and a cutback in wild fires, resulting in an opaque shrub

These are commonplace attributes of commercial forests. Jeopardized populations are identified with disintegrated forests surrounded by highways and urban areas. The size of the habitat is determined by the seasonal and spatial circulation of food, population quantity, reproductive condition, and human-related impact. Female Florida black bears choose a home established on the scarcity of food in the area. Male black bears settle in a home spectrum in relation to the quantity of females in the area. Male’s home ranges are normally 3-8 times as full as those of females. The magnitude of the home range of these bears fluctuate extensively, due to the array of habitats and their
The Pygmy three-toed- sloths are described to have buff-colored faces with dark circles that surround the eye and go outwards to their temples. Like all sloths, they are always in doldrums which can be very unbeneficial to them. They have clay-orange fur that covers their face and their hair is long and bushy. “Long hair hangs forward to the forehead, giving the impression of a hood” (Grzimek 161). Their outer fur has coated an alga that is used as camouflage to avoid predators. If they were attacked, they have a high probability of surviving due to their ability to heal from grievous wounds. These sloths have a total of 18 teeth, 10 coming from their upper jaw. Similar to other sloths their body temperature regulation is imperfect (“Bradypus pygmaeus pygmy three-toed sloth” (a)).
Grizzly bears live in a variety of environments .All of which includes dense forests, subalpine meadows, open plains and arctic tundra . In the past though, they could be found from Alaska to Mexico, and from California to Ohio. Though Nowadays there are efforts trying to make it so grizzly bears can make a comeback and the wild, and all of their efforts are proving to be working, there are 4 times as many grizzlies in the wild as there were in 1975, at
amount of game allowed to kill. Today we have an abundance of deer in Kentucky,

In this research paper, I will address the changes that occurred within the ecosystem of Yellowstone National Park since the reintroduction of the grey wolves. The paper will consist of four sections; the first section will include the history behind the extirpation and subsequent reintroduction of the gray wolf in Northern America. The second section will explore the political controversy that surrounds the reintroduction of the gray wolf in Yellowstone. The third section will contain discuss the gray wolf and its impact on the ecosystem of Yellowstone. I will conclude my essay by explaining how the gray wolves act as climate change buffers in Yellowstone amidst global warming.
Within the state of Florida there are dozens of individualized, non-profit organizations making an effort to help the local wildlife. The local land and marine wildlife includes birds, geckos, frogs, snakes, panthers, manatees, sea turtles, fishes, sharks, corals, lizards and many, many more. Florida State is located on the Southeastern tip of the United States providing a unique opportunity for conservation of salt-water animals. While there are animal conservation efforts taking place all over the world, this essay will focus on two animal species that humans are specifically trying to save in Florida State. The two main animal species of focus are manatees and sea turtles.

The characteristics of the grizzly bear as a top predator also make it highly vulnerable to threats. Although it is an omnivore, because it relies heavily on salmon to make it through the winter, it is vulnerable to anything that impacts on salmon runs. It needs wide-ranging habitat and is slow to reproduce. As such, grizzly bears are considered not just a key species but also an ‘umbrella species’ because the protection of their habitats will result in an ‘umbrella of protection’ for a wide range of other species. The protected areas that have been set aside in the Great Bear Rainforest are not enough to sustain healthy populations of grizzly bear so it requires additional habitat set aside from logging. Trophy hunting of grizzly bears also continues to place their population at
The Everglades is a diverse ecosystem located in southern Florida, yet urbanization has created a considerable amount of impact that has altered the physical landscape of the region, resulting in a symbiotic environment between humans and nature. Based on geographical research, the original Everglades spanned an area of approximately 12,000km2, and now because of urbanization and agricultural growth in this sub-region the area of the Everglades has been condensed to half of its original size (Willard et al 1-2). The Everglades is actually a sub-region of the Southern Coastlands region of the United States. It is comprised of a unique climate, divided into sub-provinces that create a diverse pallet of environments for wildlife to thrive, yet the impact of human modifications over a period of decades has drastically effected animal populations, and changed the functionality and physical landscape of its expanse. Despite the differences of urbanization and wildlife, major cities and the ecosystem of the Everglades thrive and fuse together to form the diversely changing landscape of the modern Everglades.
In the last decade, from the Rockies to New England and the Deep South, rural and suburban areas have been beset by white-tailed deer gnawing shrubbery and crops, spreading disease and causing hundreds of thousands of auto wrecks. But the deer problem has proved even more profound, biologists say. Fast-multiplying herds are altering the ecology of forests, stripping them of native vegetation and eliminating niches for other wildlife. ' 'I don 't want to paint deer as Eastern devils, ' ' said Dr. McShea, a wildlife biologist associated with the National Zoo in Washington, ' 'but this is indicative of what happens when an ecosystem is out of whack. ' ' The damage is worse than anyone expected, he and other scientists say. Higher deer densities have affected growth, survival, and reproduction of many plant species which have aesthetic, economic or ecological value. In some cases, many species of trees have also been shown to have reduced growth as a result of high deer density (Environmental Benefits of Hunting, 1). Deer prefer certain plant species over others and frequently feed on economically valuable tree species. For example, they prefer oak and sugar maple seedlings, as well as acorns, over less palatable species like American Beech and striped maple. Thus, less marketable species are more likely to survive to maturity,
In comparison, wolves were gone from Yellowstone for more than 70 years. While they were gone, the ecosystem continued to function properly. With the gray wolf returning, the ecosystem improved. Yellowstone depends on the gray wolf to hel...

According to the Alaska Department of Fish and Game, the brown bear is located all throughout Alaska, mostly in areas that allow them to seasonally hunt salmon (Alaska Fish & Game, 2010). This allows them to become larger and live in higher concentrations than the grizzly bear. The traditional brown bear and the grizzly bear are actually both classified as brown bears, despite having several differences in appearance. Brown bears are one of the most fascinating and powerful species in the Alaskan wilderness. Cubs are usually born during January or February, usually in groups of one to four (Alaska Fish & Game). A fully grown, male brown bear can weigh up for 1,500 pounds and be over 10 feet in stature (Alaska Fish & Game, 2010). Brown bears also have the ability to run at speeds up to 40 mph for short bursts of time (Alaska Fish & Game). All of these unique characteristics make many people upset that it is legal to hunt them. There are several groups that are working to conserve the brown bear population, particularly in Alaska, such as The Northern Forum’s Brown Bear Working Group (Fish & Wildlife Journal, 2010). The bear population in Alaska is thriving and is classified as a status of least concern, by the IUCN Red List (IUCN, 2010). Overall, the brown bear population faces no danger whatsoever.
What animal is black and white and loved all over the world? If you guessed the giant panda, you're right! The giant panda is also known as the panda bear, bamboo bear, or in Chinese as Daxiongmao, the "large bear cat." Actually, its scientific name means "black and white cat-footed animal." Giant pandas are found only in the mountains of central China. They live in dense bamboo and coniferous forests at altitudes of 5,000 to 10,000 feet. The mountains are covered in heavy clouds with torrential rains or dense mist throughout the year. Giant pandas are bear-like in shape with striking black and white markings.
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
