...The Survival And Cubbing of Polar Bears The survival and cubbing of Polar bears is rapidly getting affected due to climate change and Global Warming, as says the Wildlife technical report(Michelle Allsopp, 2012). The healthy breeding of Polar bears relies greatly on the Arctic’s ice covered waters and cultivate Arctic Wildlife, as well. Polar bears are the most precious habitats of Arctic wildlife, Not only because they are limited in numbers but also on the grounds that the specie have now endangered for conservation. According to authentic information(Michelle Allsopp, 2012), a female Polar bears can only give birth to 1 to 3 cubs with in life time. Also, the mortality rate of infant cubs exceed from 70 %. Hence, there are less chances that the individuals of the Polar bears can be replaced by new generations. Furthermore, the other factors of climate change and global warming have intensified the threat to the species conservation due to climate changes in Arctic Wildlife. The projected claim can be justified with supporting observations presented below for reference. * Comprised survival rates of sub adult due to poor nutritions resulted from the sea ice breakup. * Inefficient reproduction cycle due to early spring ice breakup. * Deprived access to prey for sufficient...

...foraging and whether or not the species is considered a generalist or a specialist. Every animal uses its own attack strategy when it comes to foraging behavior and their prey have their own technique on how to Lessing there changes of being eaten. Our textbook defines optimal foraging as the most efficient way for an animal to obtain food. You would think that animals just eat whatever they see and what’s available but this hypothesis is absolutely wrong. According to Darrell Ray, an American Biology teacher human also go through a phase of optimal behavior. Darrell did an experiment with his general ecology class involving a plate of cookies and broccoli. In his experiment he polled how many students would choose a cookie over broccoli. At the end of his experiment he asked his students why did the majority pick cookies over broccoli. There response was because of the taste. Optimal foraging theory suggests a different answer, and it lies in the economic principle of profitability.” Fats and sugars do taste good, as the students noted, but sugars have the added benefit of providing a rapidly available energy boost, while fats have high caloric density. () Grizzly bears are used in the textbook to illustrate optimal foraging in animals. Grizzly bears are characteristic as being a generalist species. According to North American Animals, Grizzly bears are omnivorous and will eat nearly any nutritious foods which include...

...regulate it efficiently. (Pierotti, 1980) Sharing a similar environment to the pinnipeds we have the polar bears (Ursus maritimus) that have their own unique way in which to maintain a body temperature that remains in equilibrium. Polar bears can regulate their body temperatures not only through their physiological tendencies, but also through their behavioral tendencies. Unlike most types of bears, polar bears are unique in the fact that they tend not to hibernate in the winter months and choose to devote this time maintaining a constant body temperature. Unlike the animals previously talked about the polar bears thermoregulation is about preventing hyperthermia because of how well suited they are for the freezing environment. Polar bears primarily lose their heat from their limbs as well as from their nose and the type of heat loss is depend on what processes are carried out where on the body. Radiation heat losses of the resting polar bear are around 36-67% of the energy obtained from metabolism and with only a small percent resulting from respiratory heat losses (from the nose), the remainder is lost through convective heat lost through the footpads, “arm pits”, and shoulders by moving their limbs, which are well vascularized and where there is more absent fur enabling more heat exchange to occur. (Best, 1982) Similar to many animal species the ways in which the polar bear alters its physiological tendencies in order to minimize its overall heat loss is by increasing the amount...

...about the cute, white polar bears living up in the north. However, one thing you may or may not know is that because of the high demand of polar bear fur, their meat being one of the main sources of food for the native people of the north, and tourist not being careful when visiting polar bear habitats, the polar bear population in Canada has started to decline at a rate which may cause them to become endangered and then extinct in the near future. Now with polar bears being the main predators in the North Pole and the largest land predators in the world, a threat to the polar bear population is a very big deal and would have a big impact on the terrestrial and aquatic ecosystems up in the northern regions. Polar bears...

...and explore, or do nothing? This is what happened to Brian Robeson. Brian was able to survive in the woods because he used survival strategies. To survive in the woods, Brian Robeson used trial and error, became more observant, and used his hatchet his mother gave to him. In order to survive, Brain used trial and error. When the pilot had a heart attack, Brain had to steer the plane so it wouldn't crash into the trees. He steered it up and down to fly the plane. Going up went too violently, going down increased speed, and pulling back gently floated the nose up and the engine settled. A few days after landing, he decided to make a fire. He thought rubbing two sticks together would work, like in the movies, but it failed. At night, porcupine appeared and Brian threw his hatchet at it. The hatchet missed and hit a rock. He noticed it created sparks. He hit rocks with his hatchet rapidly to make his first fire. He hunted for fish for food. He made a bow to catch fish in the river. Brian shot the arrow but it missed. He forgot water refracts, or bends light which he learned from biology class. Brian aimed under the fish to catch them and he succeeded. With trial and error he was also observant....

However it wasn't until 1920 that American football achieved a league of any true organization. Roussel, 2 The American Professional Football Association was formed on September 17, 1920 and included ten teams from four different states. However the APFA lasted only two seasons when it was reorganized on June 24, 1922 into the National Football League. The only two teams still in the NFL from the inaugural class, the Decatur Staleys (now the Chicago Bears) and the Chicago Cardinals (now the Arizona Cardinals), are founding members.

...Arctic Home Campaign Coca- Cola Presented to Mutar Kent CEO and Chairman of the Coca-Cola Company March 8th 2012 March 8th, 2012 Muhtar Kent CEO and Chairman of the Coca-Cola Company Dear Mr. Kent, Although raising awareness for the polar bears habitat is critical, study has shown that the company’s campaign to save the polar bears by the changing the colour of the Coca-Cola cans has been ineffective. Many consumers were mislead by the change of colour of the cans. The new white Coca-Cola cans are too similar to the Diet Coke cans. In today’s society, consumers have been accustomed to brand recognition and do not take time to read labels. Many consumers accidently bought regular Coca-Cola thinking they were purchasing Diet Coke. The purpose of changing the cans to white is to promote awareness to the polar bears habitat and raise money for the cause. Many do not know how to donate to the campaign. It was unclear to many consumers the reason for changing the colour of the cans. The change brought more confusion than it did awareness to the polar bears. I am thankful for the 25 participants who gave me their time in order to complete the questionnaire survey, as well as Maria-Jose Errunza and my classmates of Comm 212 who have helped me with this report. Their contribution is greatly appreciated. Thank you for the attention given to this report. You may contact me at 438-886-8012 should you need further clarification in regards to...

...DEFINITION FROM WIKI (understand and write it yourself) In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbanceby resisting damage and recovering quickly. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation and the introduction of exotic plant or animal species. Disturbances of sufficient magnitudeor duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates.Human activities that adversely affect ecosystem resilience such as reduction of biodiversity, exploitation of natural resources,pollution, land-use, and anthropogenic climate change are increasingly causing regime shifts in ecosystems, often to less desirable and degraded conditions. Interdisciplinary discourse on resilience now includes consideration of the interactions of humans and ecosystems via socio-ecological systems, and the need for shift from the maximum sustainable yield paradigm to environmental management which aims to build ecological resilience through "resilience analysis, adaptive resource management, and adaptive governance". The concept of resilience in ecological systems was first introduced by the Canadian ecologist C.S. Holling in order to describe the persistence of natural systems in the face of changes in ecosystem variables...

...Davy Crockett was born in Greene County, Tennessee August 17, 1786. He had many tall tales about himself. A few examples are that he can jump riverbanks and fight bears. Davy Crockett was a congressman, a frontiersman, and the defender of the alamo. Son of John Crockett and Rebecca Hawkins Crockett. When David Crockett was 8 years old his father John Crockett gave up on farming. David’s dad had got a friend to help him build a gristmill, so that way the river would power up the gristmill. The gristmill would grind grains into flour and they could sell it t the neighbors. Before they could finish building the mill the water at the area flooded and it floated away. At age ten Davy learned how to hunt he had a sharp eye with a shot that would be right on target. When David was thirteen a one room school by his house opened up. Him and his older brothers attended. They learned reading, writing, and math. For a while Davy would set off for school, but then hid in the woods. Finally the schoolmaster sent a note to his father asking where was David. John Crockett was...

...considerations ORANA should have, when choosing between, for example, Peru or New Zealand. Entering a new market is an important decision, so ORANA has to consider many aspects carefully before making the decision on which country to enter. According to the Market-based view a company which wishes to enter a new market has to consider market conditions of the nation. The theory states that the competitive advantage comes from the market itself and the external environment of the firm. The company has to find the market from where it can gain competitive advantage. For deciding on which market to enter, Porter five forces, as a framework for industry analysis can be a great help. This framework is very useful when it comes to business strategy development. Porter says that the nature and degree of competition depends on these five forces: threat of new entrants, bargaining power of customers, bargaining power of suppliers, threat of substitute products or services and the intensity of competitive rivalry (Porter, 1979). To enter into a new market, ORANA has to be aware of the current market situation and the state of the competition. The Danish manufacturer has to make a research on these five forces and get to know the more they can about the state of the competition. To get the proper information they have to make market research, going to the field or find a partner from Peru and New Zealand who they trust and provide them reliable data. For further research it is advisable...

...[pic] Reflective Practice EDU 2071-N Critically Evaluating Reflective Practice. Leigh William Adams. M1106275 D.O.S: 10/12/2015 Word count: 2000 Introduction. This essay will look at the use of reflective practice in a vocational construction setting, it will look at various practitioners’ theories and how they may be implemented into the current strategy. Reflective practice can be an essential tool in vocational based professional learning settings where people learn from their own experiences, rather than from formal learning or knowledge transfer. It may be the most important source of personal professional development and improvement. It is also an important way to bring together theory and practice; through reflection a person is able to see and label forms of thought and theory within the milieu of their work. The essay will also look at the use of reflective practice with learners at a behavioural school. Each section will cover different topics, section one will cover the understanding of critical reflection, section two will show how critical reflection is used for behaviour, section three shows its use in the construction industry and section four will briefly cover other authors and their respective models. Section 1. In order to be effective teachers must be reflective; they must continuously review their practice, discuss it with their colleagues, consider their learners’ responses and seek to develop...

...Prisoner's Dilemma (Stanford Encyclopedia of Philosophy) 4/3/12 9:58 AM Open access to the SEP is made possible by a world-wide funding initiative. Please Read How You Can Help Keep the Encyclopedia Free Prisoner's Dilemma First published Thu Sep 4, 1997; substantive revision Mon Oct 22, 2007 Tanya and Cinque have been arrested for robbing the Hibernia Savings Bank and placed in separate isolation cells. Both care much more about their personal freedom than about the welfare of their accomplice. A clever prosecutor makes the following offer to each. “You may choose to confess or remain silent. If you confess and your accomplice remains silent I will drop all charges against you and use your testimony to ensure that your accomplice does serious time. Likewise, if your accomplice confesses while you remain silent, they will go free while you do the time. If you both confess I get two convictions, but I'll see to it that you both get early parole. If you both remain silent, I'll have to settle for token sentences on firearms possession charges. If you wish to confess, you must leave a note with the jailer before my return tomorrow morning.” The “dilemma” faced by the prisoners here is that, whatever the other does, each is better off confessing than remaining silent. But the outcome obtained when both confess is worse for each than the outcome they would have obtained had both remained silent. A common view is that the puzzle illustrates a conflict between individual and...
