What Is an Edge Habitat

Across the globe, human development has fragmented once-continuous landscapes and ecosystems into isolated patches of natural habitat. Roads, towns, fences, canals, reservoirs, and farms are all examples of human artifacts that alter the pattern of the landscape. At the edges of developed areas, where natural habitats meet encroaching human habitats, animals are forced to adapt quickly to their new circumstances--and a closer look at the fate of these so-called edge species can give us sobering insights into the quality of the wild lands that remain. The health of any natural ecosystem depends significantly on two factors: the overall size of the habitat, and what is happening along its edges. For example, when human development cuts into an old-growth forest, the newly exposed edges are subjected to a series of microclimatic changes, including increases in sunlight, temperature, relative humidity, and exposure to wind. Plantlife and Microclimate Create New Habitats Plants are the first living organisms to respond to these changes, usually with increased leaf-fall, elevated tree mortality, and an influx of secondary-successional species. In turn, the combined changes in plant life and microclimate create new habitats for animals. More-reclusive bird species move to the interior of the remaining woodland, while birds better adapted to edge environments develop strongholds on the periphery. Populations of larger mammals like deer or big cats, which require large areas of undisturbed forest to support their numbers, often decrease in size. If their established territories have been destroyed, these mammals must adjust their social structure to accommodate the closer quarters of the remaining forest. Fragmented Forests Resemble Islands Researchers have found that fragmented forests resemble nothing so much as islands. The human development that surrounds a forest island acts as a barrier to animal migration, dispersal, and interbreeding (its very difficult for any animals, even relatively smart ones, to cross a busy highway!) In these island-like communities, species diversity is governed largely by the size of the remaining intact forest. In a way, this is not all bad news; the imposition of artificial constraints can be a major driver of evolution and the flourishing of better-adapted species. The problem is that evolution is a long-term process, unfolding over thousands or millions of years, while a given animal population may disappear in as little as a decade (or even a single year or month) if its ecosystem has been wrecked beyond repair. The changes in animal distribution and population that result from fragmentation and the creation of edge habitats illustrate how dynamic a cut-off ecosystem can be. It would be ideal if—when the bulldozers have disappeared—the environmental damages subsided; unfortunately, this is rarely the case. The animals and wildlife left behind must begin a complex process of adaptation and a long search for a new natural balance. Edited on February 8, 2017, by Bob Strauss

Brittany Portwood EDUC 2130 Dalton State College March 23, 2017 Introduction Psychology is full of theories that explain why we think the way we think. Of those theories, is the popular Piaget’s theory of cognitive development. Jean Piaget introduced a variety of ideas and concepts to the world of psychology describing logical thinking in children and adolescents. To fully comprehend just how valuable his theories are today, it is important to explore the life of Jean Piaget, his educational background, and the stages of cognitive development and how the stages impact the classroom. This will give a further analysis and explanation of how Piaget has helped to shape our viewpoints as teachers today. Biographical Background of (Jean†¦show more content†¦By studying the cognitive development of children and adolescents, Piaget identified four major stages of mental growth which are sensorimotor, pre-operational, concrete, and formal operational. He believed that all children pass through these phases to advance to the next level of cognitive development and in each stage children demonstrate new intellectual abilities and increasingly complex understanding of the world (Zhou Brown, 2015). He also believes that no stages can be skipped and that the intellectual development always follows the sequence. The first stage of Piaget’s cognitive development is sensorimotor, which begins at birth and last until eighteen months to two years of age. This stage is the use of motor activity without the use of symbols, so when it comes to this stage is based on physical interactions and experiences and knowledge is very limited. Infants cannot predict reactions and therefore must constantly experiment and learn through trial and error (Zhou Brown, 2015). A good example of this would include shaking a rattle or putting objects in the mouth. As infants become more mobile their ability to develop cognitively increases and early language development begins. Object performance also occurs at seven to nine months, demonstrating that memory is developing. The next stage is the pre-operational stage, which usually occurs during the period of twenty-four

Negotiation Case Essay Example

Negotiation Case Essay Post-Negotiation Analysis For The Paradise Project In this case, I was playing the role of chief project manager of the Paradise Project, and I was negotiating with my Manager of Artistic Design (Angel) and Manager of Client Contracts and Customer Relations (Elion) in order to resolve the conflict between each of them. Overall, I was satisfied with the final agreement, which paid 3,000 more pesos to Angel and ensured that he would change the color of the tiles and finish the job before the deadline. At the same time, Elion would be helping him get the work done. Because we were able to reach a mutually satisfying agreement, I would like to analyze three aspects of our negotiation process; how I implemented it as a chief manager, what I learned from it, and how I can improve my negotiating skills in the future to achieve even better results. First of all, because I was playing the role of chief manager of the project; I assumed that I should be the one that controls the meeting. Therefore, I set up a brief outline for this negotiation before we met each other, and tried to keep our discussion organized. I think this was one of the significant factors that helped me steer the whole meeting toward my target outcome. Secondly, I didn’t spend too much time talking, instead, I spent lots of time asking them questions and listening carefully to their responses. I believe that nobody likes being asked to do something, but people usually like to provide ideas about how to do something.

Although some of their proposals weren’t feasible, I didn’t reject them outright, at least not at first. I pointed out the difficulties and allowed them to rethink. In fact, by employing these three strategies as a manager, I achieved a deal that was close to my target outcome, even better than my BATNA. After the meeting, I figured out that I made the mistake of treating both Elion and Angel as subordinates on the same level as each other. In fact, as a manager of client contracts and customer relations, Elion should have a closer relationship to me because it’s both of our jobs to get the project done and satisfy our clients. For Angel, the artistic value of his work is most important. Therefore, I should have considered each individual’s relationship towards me more clearly so that I could control the negotiation process even better. In addition, I figured out finding common interests amongst each party are crucial for finding a mutually agreeable solution. Angel was confident about his design. If I wanted him to change his color choice, I would have needed to convince him that changing his design doesn’t necessarily mean that he made a bad choice, only that it is a client request. Even though I reached an agreement efficiently, I still need to improve my negotiation skills. First, I should have been able to consider if there is another option besides of changing the color. For example, the option of keeping the color, and then convincing our client to accept it. Second, I could have been more aggressive during the meeting in order to save as much money as possible. Because I am the chief manager, and any extra cost will directly create a negative effect on my supervisor’s evaluation of me. To sum up, participating in this case gave me an opportunity to understand how a chief manager should perform in a negotiation process. By reviewing the result, I have learned I considered more clearly each party’s relationship towards me, and I should been more aggressive during the meeting to purse them. I am looking forward to the next one.

Solar Energy - The Energy Of The Future Essays - Energy Conversion

Solar Energy - The Energy Of The Future? About 47 per cent of the energy that the sun releases to the earth actually reaches the ground. About a third is reflected directly back into space by the atmosphere. The time in which solar energy is available, is also the time we least need it least - daytime. Because the sun's energy cannot be stored for use another time, we need to convert the suns energy into an energy that can be stored. One possible method of storing solar energy is by heating water that can be insulated. The water is heated by passing it through hollow panels. Black-coated steal plates are used because dark colours absorb heat more efficiently. However this method only supplies enough energy for activities such as washing and bathing. The solar panels generate "low grade" heat, that is, they generate low temperatures for the amount of heat needed in a day. In order to generate "high grade" heat, intense enough to convert water into high-pressure steam which can then be used to turn electric generators there must be another method. The concentrated beams of sunlight are collected in a device called a solar furnace, which acts on the same principles as a large magnifying glass. The solar furnace takes the sunlight from a large area and by the use of lenses and mirrors can focus the light into a very small area. Very elaborate solar furnaces have machines that angle the mirrors and lenses to the sun all day. This system can provide sizeable amounts of electricity and create extremely high temperatures of over 6000 degrees Fahrenheit. Solar energy generators are very clean, little waste is emitted from the generators into the environment. The use of coal, oil and gasoline is a constant drain, economically and environmentally. Will solar energy be the wave of the future? Could the worlds requirement of energy be fulfilled by the "powerhouse" of our galaxy - the sun? Automobiles in the future will probably run on solar energy, and houses will have solar heaters.

Animal Farm, Great Expectations, and an Outpost of Progress Essay Example

Animal Farm, Great Expectations, and an Outpost of Progress Essay Example Animal Farm, Great Expectations, and an Outpost of Progress Paper Animal Farm, Great Expectations, and an Outpost of Progress Paper Essay Topic: Animal Dreams Animal Farm Great Expectations The answer is simple, the use of satire. From the moment Pip is introduced, to the point in which him and Estella supposedly fall in love, Dickens has placed his sense of satire to please the readers sense of feelings for the characters. This young boy named Pip was not raised in the richest family in the world, so he is elated that his uncle has set him on a meeting with one of the wealthiest old woman In England. Upon arrival a beautiful little girl about his age welcomes him. The old woman, Ms. Having, tells this little girl, Estella, to play with Pip and show him the ropes of being In a high-class society. More Importantly Ms. Having tells Estella to somewhat fall for Pip, and It works. As the reader you see the Irony that this Is all a ploy to destroy a little boys state of mind, and to break his heart which Is stated In this passage, Well, I thought I overheard Miss Having answer- only it seemed so unlikely- Well, you can break his heart. (Dickens 61 ) But Dickens wants Pip to feel the irony, so what better way to do it than having the girl of is dreams tell him, You must know, said Estella, condescending to me as a beautiful woman might, that I have no heart. (Dickens 235) It is a perfect way to leave the reader double-checking all that they read, and it is an even better way of introducing a little chaos in the story. Animal Farm, In short, Is about the time and events of World War II and the Russian Revolution. If a reader doesnt know this then they might not have gotten the irony and chaos presented by George Orwell. For example, after Mr.. Jones was over heron from his own far m, the animals took over; more specifically the pigs took charge. The pigs, including Snowball and others, decided they where smarter and Tanat teen snouts run ten Tara. Nine animals as a wangle Ana agreed, ten Irony, ten pigs sat around and encouraged the animals to work while they reaped the benefits. These leaders had become dictators. Orwell was able to take some of the worst stories and people of the time and turned them into animals. By saturating his story, people could distance themselves from the horrors of war. It was almost as if he wrote a fairy tale for adults. Animal Farm is a story full of saturating from point A to point B and is used in what seems to be every last sentence. A simple quote from the book showing satire, All animals are equal but some animals are more equal than others. (Orwell) The saturating in Outpost of Progress is very easily seen, Just read the title. Even more ironic than the title is that the two main characters, Asserts and Carrier, are probably the laziest people ever put into a story. And of course these lazy men set the stage for a tale meant to be about progression, which, there seems to be none of. When the story takes place, it is during the time of colonialism in Africa, which is where the story is taking place. Through out the book these men are supposed to sell things to the tribesmen and people around their outpost. But due to the lack of people in the area things Just tend to sit in the shop and the two men Just sit. So what happens when there is only one cube of sugar left for their daily cup of coffee? Simple, the lazy men actually have to fight for it. Had this happened at the beginning of the story these men would have stuck to their morals and not have even thought of sighting over something so stupid. But being in this heat, without friends or loved ones tears them down limb by limb. The only progress in the entire story is the death of both of the men, over a cube of sugar. It is like Conrad meant for this story to be written based purely on saturating stating this in the book, The courage, the composure, the confidence; the emotions and principles; every great and every insignificant thought belongs not to the individual but to the crowd: to the crowd that believes blindly in the irresistible force of its institutions and of its morals, in the rower of its police and of its opinion. (Conrad, page 193) It is easy to conclude that satire is something that is placed in many books for the enjoyment of the reader. Without it many story lines would be dull and not worth reading. So for the sake of expressing their inner humor, authors insert satire where they can. As stated, Great Expectations, Animal Farm, and An Outpost of Progress are clear reminders of great and timeless stories that without some of the corruption and irony wouldnt be the classics they are today.

The Evolutionary Changes in Construction Between the De Havilland Essay

The Evolutionary Changes in Construction Between the De Havilland Comet and the Airbus A380 Aircraft - Essay Example In addition, the jetliner also had a large square window and a pressurized fuselage. Regarding the era, the Comets provided a comfortable passenger cabin. It made its first commercial debut in 1952 where it flew without any problem. Its successful debut as a commercial jet helped drew passengers from all parts of the country with an interest in using the Comets as their preferred choice of flight. However, the success stories of the Comets did not last long since the airplane began experiencing problems just a year after its commercial service debut. In fact, three of the Comets broke up while, on flight resulting in an accident, that received wide publication by the media, according to Montagu-Pollock (2012). Investigations that followed showed that the accidents occurred due to catastrophic metal fatigue that the manufacturing engineers did not understand property at the time of its manufacturing. This prompted the withdrawal of the Comet from service after which it was taken for e xtensive testing to unearth the real cause of the accident. Investigations showed that the accident had initially been wrongly blamed on poor weather. Instead, design flaws were identified, which included dangerous installation methodology, and dangerous stresses at the corners of the windows. As a result, the Comet was modified with oval windows and structural reinforcements among many other changes, notes Nolan (2010). The other rival manufacturers of aircrafts learnt from the Comet and began making improvements in their while manufacturing processes avoid the mistakes made during the manufacture of the first Comet. Overview of the construction design of the Comet The first De Havilland Comet was made entirely of metal low-wing cantilever monoplane, observed Montagu-Pollock (2012). They had four engines, two of which were mounted below the wings for powering the plane. The two engines were buried under the wings to prevent the drag of podded engines, as well as to give room for sm aller fin and rudder. The mounting of the engines higher in the wings was also meant to reduce the risk of injection damage, which had been a major problem associated with turbine engines. It also had four-place cockpits for two pilots, navigator, and a flight engineer (Nolan 2010). Unlike the features of the aircrafts of the time, the first Comet had a clean low-drag design, which included the swept-wing leading edge, four-wheel bogies, and integral wing fuel tanks. The original De Havilland Comet measured almost the same length as the later Boeing 737-100. However, it carried fewer people in a spacious environment than the Boeing 737-100 (Birtles 1990, p.11). The British Overseas Airways Corporation (BOAC) installed 36 reclining ‘slumber seats’ with center measuring about 45-inches allowing for a greater leg space both behind and in front. Air France, on the other hand, was fitted with 11 rows of seats plus four seats installed on its comets. The plane also had tables where passengers can have the feeling of enjoyment and comfort. Amenities included a large galley capable of serving hot and cold cuisines and drinks, according to Ron and Patterson (2010, p.19). It also had toilets for both men and women. Because of the safety concerns, the airplane had an emergency section, which included several life rafts kept in the wings, just next to the engines. However, after encountering problems while, on flight, several improvements have been made to ensure that such accidents do not occur
