1911, Southern sea otters swam on every coast near the Pacific, Including the Sea of Japan. They lived in large kelp forests near shores and would usually stay on the surface of the water only diving when food was necessary. Being the most important part of the food chain, sea otters kept anything that would eat the seaweed like snails, and sea urchin populations in check so the kelp forests wouldn 't die out. Southern sea otter populations near the west were unknown, but the American east coast has around “15,000 otters through 1911 to 1928 and growth kept going”(The Monterey Bay Aquarium).
The author states that the pollution hypothesis seemed the most likely cause of otters decline along the Alaskan coast and provides three reasons. In contrast, the professor states that the ongiong investigation show that the predation theory is mst likely the cause of the decline and sh.e opposes each of the author 's reasons
The successful return of sea otters on North America’s west coast Though the Gold Rush of 1849 is considered one of California’s significant historical events, the Californian Fur Rush is much overlooked in Pacific America’s history. Dating as far back as 1741, the Californian and Alaskan coasts were targeted by American, English, Spanish, French and Russian fur traders harvesting the warm pelts of the sea otter, fur seal, beaver, river otter, marten, fisher, mink, fox, weasel, and harbor seal. Sea otters (Enhydra lutris) were particularly overhunted and their populations suffered serious fragmentation up the west coast, coming dangerously close to eradication in this area (Estes, 1990). This essay will discuss the history of their decline
In the 1900s the population decreased because of the DDT ( DDT: dichlorodiphenyltrichloroethane) sickness with the eagles. Hunters are a treat to bald eagles because they will shoot them out of the sky. If a bald eagle eats a duck that has been eating lead shots that
Beaver marshes where otters, mink, muskrats and ducks could nest,” Bring back a predator that we took away in the first place had a huge positive effect on the land and animals around it. Having the top predators is the best way to go, they were placed on the earth for a reason and who are we to take that away. In conclusion, if we continue to kill of animals as we are doing now, the next 10 years will change horrifically. As Anthony Froude says, “Wild animals never kill for sport. Man is the only one to whom the torture and death of his fellow creatures is amusing in
This is why wolves need to stay on the island to control the biotic community and environment. As you can see, wolves are an important factor in the health of Isle Royale. Without them the whole island could perish. That’s why we can’t let them become extinct from the island. In conclusion, new wolves need to be brought to Isle Royale in order to repair the balance of the ecosystem and the overall well-being of the
The monk seals are a rare tropical animal that lives on the Caribbean and the Hawaiian Islands. Monk seals live in warm waters and spend about two-thirds of their time at sea. However, they also spend time on land as they breed and carry-out their “pups.” Coral reefs provide the seal as a great habitat for them to dive, swim, and for food such as fish. It may seem that monk seals spend most of their time at sea, but they also love to rest on shore on the beaches. From resting and birthing to nursing newborn seals, the seals try their best to survive. Why are these animals extinct, then?
The United States of America abounds with beautiful scenery, amazing natural resources, and fascinating animals. Each state can boast of its unique natural resources. The state of Alaska provides an abundant habitat for numerous species of mammals, fish, and birds.
In both of these articles by Christine Dell’Amore and Matt Miller, they discuss how these top predators impact the island, why they are they important, and should humans interfere? On the island of Isle Royale, there is a variety of animals that mostly just consume vegetation; therefore, they need wolves to balance out the food chain. But, the island is only accessible during the winter when stable ice bridges are created. Unfortunately, the ice bridges have not been forming due to warmer winters. Leaving a small count of wolves on the island with no new genes to mix in.
Starting from the way they are captured, these animals suffer all their life in confinement. Currently, 58 orcas are held captive in different marine parks around the world. (The fate of captive orcas). At the moment of their capture this animals are hurled in and the young ones are captured, leaving the parents in despair over their offspring’s. (blackfish).
Keeping Whales in Orcas is Not Right! By Kira Hampton Should we keep Orcas in captivity? No! It is not right! Imagine living in a bathtub your whole life.
Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,
Have you ever thought about which animals are near extinction or endangerment ? Have you looked them up? How many are left? Which ones have been removed? Do you know why they are going endangered?
They are on the endangered species list since November 2013. They are also protected
Animals in Their New Natural Habitat Why are different species becoming extinct? Do researchers know how many innocent animals are killed each year? When will animals be protected in a comfortable habitat? In man-made environments, such as zoos and other nature parks, animals that are born in the wild are protected and well taken care of. Due to animals running around in the wild, scientists and researchers can track the amount of animals being killed everyday.
