The U.S. Fish and Wildlife Service is once again threatening to remove grizzly bears from the Endangered Species list. While the grizzly bear population in the Greater Yellowstone Ecosystem has increased since the bears were added to the listing in 1975, the struggles to survive continue (U.S. Park Service). The Defenders of Wildlife agree that the government needs to keep protecting the grizzly bear because of the threats of human encounters, habitat availability and climate change.

First, human encounters are a risk to the survival of grizzly bears. The National Park Service at Yellowstone reports that the management of grizzlies will not change within the park if these animals are removed from the list. Hunting will still not be allowed in the area. However, grizzly bears do not know the boundaries of the park. The states that surround the area could allow hunting of these animals during their regular seasons. As a result, the population of grizzly bears would decline.

Next, habitats for grizzly bears are still fragile. The Greater Yellowstone Ecosystem is an ideal place for these bears to live and thrive, but outside the area there are many dangers. Humans continue …show more content…
According to David Matton, a research scientist from Yale University, the population of grizzly bears are affected by the growth of the whitebark pine (Pappas). Climate change has been linked to the increase of pine beetles and “blister rust” which is wiping out these trees. With the drop in food supply, the bears are seeking other sources of food such as garbage, livestock and crops. Other impacts of climate change is that bears are denning later which means they are exposed during traditional hunting seasons. Unfortunately, these bears are victims of unintended shootings. Climate change continues to be a serious issue for the world and its consequences on grizzly bears will also

...Grizzly bears http://www.care2.com/causes/graphic-grizzly-bear-hunting-video-sparks-outrage.html are iconic on the Yellowstone National Parks landscape, so how can the United States Fish and Wildlife Service (FWS) consider delisting them? For its part, the FWS insists that the bears have recovered enough -- today there are 757 http://yellowstoneinsider.com/2015/10/22/yellowstone-area-grizzly-bears-dying-at-high-rate-in-2015/ bears compared to the 136 bears when the bears were first protected in 1975. But for American Indian tribes with deep cultural and spiritual connections to the grizzlies, the bears have not recovered enough.

May 2007 Wildlife Biology Conservation of leopard in Ayubia National Park, Pakistan Director: Dr. Daniel H. Pletscher Large carnivores are important for biodiversity and ecosystem function, yet are very difficult to conserve because of their large home ranges and conflicts with humans. I examined human-leopard conflicts in and near Ayubia National Park, Pakistan, to provide management recommendations for the conservation of leopards. Persecution of leopards by humans has been on the rise primarily due to depredation on livestock and risk to human lives. Since 1989, 16 humans have either been killed or injured in and around Ayubia National Park while leopards faced 44 human-caused mortalities during the same period. I examined the management strategy adopted by NWFP Wildlife Department for leopard conservation, identify gaps, and suggest possible management actions to mitigate the conflicts. For this purpose, I reviewed the management of carnivores including mountain lions, wolves, and grizzly bears to learn from management successes...

Is Quantum Teleportation Possible

...Is Quantum Teleportation Possible Introduction Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else. How this is accomplished is usually not explained in detail, but the general idea seems to be that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted to the receiving location and used to construct the replica, not necessarily from the actual material of the original, but perhaps from atoms of the same kinds, arranged in exactly the same pattern as the original. A teleportation machine would be like a fax machine, except that it would work on 3-dimensional objects as well as documents, it would produce an exact copy rather than an approximate facsimile, and it would destroy the original in the process of scanning it. A few science fiction writers consider teleporters that preserve the original, and the plot gets complicated when the original and teleported versions of the same person meet; but the more common kind of teleporter destroys the original, functioning as a super transportation device, not as a perfect replicator of souls and bodies. In 1993 an international group of six scientists, including IBM Fellow Charles H. Bennett, confirmed the intuitions of the majority of science fiction writers by showing that perfect teleportation is indeed possible in principle, but...

Alaska the Brand

...Alaska Brand Audit Brand Inventory History Alaska has been a unique brand for many years. Originally known as Russian America because it was owned by Russia, the origin of the name Alaska is a misconception from the first Russian explorers to venture into Alaskan waters (the original Aleut word "alaxsxaq" literally meaning "object toward which the action of the sea is directed"[Alaska]). When the United States bought Alaska, even though the price was only two cents an acre, it was known for many years as “Seward’s Folly” or “Seward’s Icebox”, after William Seward, the Secretary of State who was primarily responsible for pushing the purchase from Russia through Congress. In the early days Alaska’s brand image was mostly negative. It was known as the “Frozen North”, the “land of ice and snow”, the “land without summer”. Many of these images are from the stories and poetry of Robert Service, Jack London and their contemporaries. A good example of this writing is the poem “Cremation of Sam McGee”— see appendix II, (Service). All these extreme brand images dominated perceptions of Alaska prior to the discovery of gold in the Klondike in the late 1800s. After gold was discovered these negative perceptions were softened somewhat, though they remained rather negative—in large part due to the difficulty of living in the far north. Our Brand Survey We did a brand audit of Alaska to see how well Alaska has worked past these harsh criticisms. To accomplish this we surveyed...

Natural Resources and Energy

...------------------------------------------------- Yellowstone Ecosystem Learning Team “C” 12/7/2015 Instructor: Dr. Ted Smith Yellowstone Ecosystem One of the largest and most complicated ecosystems on Earth is the Greater Yellowstone Ecosystem. This ecosystem is home to everything from mountains, lakes, forests, geysers, rivers, and meadows. Because this area is so large, it is the habitat to thousands of different species of plants and animals. In this paper we will discuss the natural resources and energy initiatives of the ecosystem and the functions in place to actively sustain them. ------------------------------------------------- There have been many impacts associated with agriculture at the Yellowstone National Forest. Agriculture is significant part of the forest lands but it has declined over the years yet, the park continues agricultural crop. The Yellowstone ecosystem has very high plant productivity. There have been houses built in certain areas where biodiversity is most essential, exclusively around grizzly bear territory, bird habitat, and anywhere along rivers and streams. Over the last few years, climate change has impacted Yellowstone National Forest and not necessarily in a positive way. It is predicted that 25 years from now, climate change will most likely strip away from forest ecosystems, specifically the one that supports Yellowstone National Park due to rising temperatures increasing so much and having the high chance of catastrophic wildfires (Thuermer...

...Polar Bears (Ursus maritimus) in the Canadian Arctic IAN STIRLING1 and CLAIRE L. PARKINSON2 (Received 10 November 2005; accepted in revised form 25 January 2006) ABSTRACT. Polar bears depend on sea ice for survival. Climate warming in the Arctic has caused significant declines in total cover and thickness of sea ice in the polar basin and progressively earlier breakup in some areas. Inuit hunters in the areas of four polar bear populations in the eastern Canadian Arctic (including Western Hudson Bay) have reported seeing more bears near settlements during the open-water period in recent years. In a fifth ecologically similar population, no changes have yet been reported by Inuit hunters. These observations, interpreted as evidence of increasing population size, have resulted in increases in hunting quotas. However, long-term data on the population size and body condition of polar bears in Western Hudson Bay, as well as population and harvest data from Baffin Bay, make it clear that those two populations at least are more likely to be declining, not increasing. While the ecological details vary in the regions occupied by the five different populations discussed in this paper, analysis of passive-microwave satellite imagery beginning in the late 1970s indicates that the sea ice is breaking up at progressively earlier dates, so that bears must fast for longer periods during the open-water season. Thus, at least part of the explanation for the appearance of more bears near coastal...

Dinosaurs in Alaska

...Dinosaurs In Alaska? When you hear a place about Alaska, we think of snow, polar bears, glaciers, and cold weather. When you think of dinosaurs, we think of tropical places and hot climates. You would probably doubt dinosaurs could have ever lived here in Alaska. But about 65 million years ago they not only lived here, they thrived! There are a lot of information about dinosaurs, but what this paper will cover is how dinosaurs directly relate to Alaska. After reading this paper, you will find out how dinosaur research started and how long ago dinosaurs lived in Alaska. Plus find out the type of dinosaurs that lived Alaska, and the type of climate and which parts of Alaska that they lived in. You will also find out what type of evidence they found, if dinosaurs are related to the oil industry, who is still studying dinosaurs, and how this topic is introduced to the public. How it all began Dinosaurs strolled the earth over 245 million years ago. So it would only be fair to go all the way back to the beginning and quickly summarize how it all happened. Earth’s history is categorized into two eras, and then categorized by periods. The two eras are Paleozoic era, and Mesozoic era. Paleozoic era - (560 to 276 million years ago): This is the period where the first fish, corals, shellfish, insects, spiders, and swamp forests appeared. Mesozoic era - (350 to 65 million years ago)We are most interested in this era. This era contained 3 periods: Triassic period, Jurassic...

Thermophilic Bacteria

...Thermophilic Bacteria of Yellowstone National Park CEE:5154 Environmental Microbiology Research Paper University of Iowa Department of Civil and Environmental Engineering December 14, 2015 Bruce McWilliams Amid the vast, sparsely populated regions of Northwest Wyoming, lies one of the most diverse and extraordinary ecosystems in the world, Yellowstone National Park. Yellowstone is one of the world's foremost sites for the study and appreciation of the evolutionary history of the earth. The park has a globally unparalleled assemblage of surficial geothermal activity, thousands of hot springs, mudpots, fumaroles, and more than half of the world’s active geysers (NPS, 2013). Yellowstone is located on top of the Yellowstone Caldera, which is a volcanic hot spot where hot, molten rock from the earth’s mantle rises toward the surface. Volcanic activity from the Caldera produces geothermal activity on the park’s surface that has drawn more than 3 million visitors to the park since 2000 (NPS, 2015). Geysers, hot springs, and mudpots are extremely toxic due to high concentrations of sulfuric acid (sulfate concentrations measure up to 925 ppm near vents) and, temperatures measuring over 100oC. Many have recorded inhabitable pH levels ranging from 2 to 9.8 (Rowe/Founder/Morey, 1973). While these colorful and wondrous hot springs may appear stagnant and devoid of life to the common park visitor, they are actually a complex, intricate habitat teeming with a diverse array...

Supernatural by Brother Branham

...Supernatural: The Life of William Branham Book 6: The Prophet and His Revelation 1960 – 1965 by Owen Jorgensen 1 Acknowledgments: In a project of this magnitude, it is understandable that I should owe many people a debt of gratitude for their help. First of all I want to thank Pearry Green for his vision, his encouragement and his efforts in publishing and distributing these books. I also want to thank Saundra Miles, David Buckley, Jay Weber, and the other people who spent many hours editing and proof reading the six manuscripts in this series. Their suggestions helped to make this a better book and a more accurate account of William Branham‘s life. Also, I want to thank Steven and Kathy Strooh, who put these books into audio format for all those people who would rather listen than read. I must certainly thank those people who have translated these books into their native languages: Spanish, Portuguese, French, German, Russian, Norwegian, Hindi, and many other languages. Supernatural: the Life of William Branham took me 17 years to complete. I was 34 when I started and 51 when I finished. To put that into perspective, my four children were in grade school when I began writing this biography. By the time I finished, three of my children were married and I had nine grandchildren. During the 17 years I worked on this project, my life had its ups and downs. I want to thank everyone who prayed for me during those 17 years. Finally I want to thank my four children—Benaiah...
