10 Facts About Lagomorphs

10 Facts About Lagomorphs Rabbits, hares, and pikas, collectively known as lagomorphs, are known for their floppy ears, bushy tails and impressive hopping ability. But theres more to lagomorphs than fluffy fur and a bouncy gait. Rabbits, hares, and pikas are versatile mammals that have colonized a wide range of habitats throughout the world. They serve as prey for many species and as such play an important role in the food webs they occupy. In this article, youll learn interesting facts about rabbits, hares,  and pikas and find out about their unique characteristics, their life cycle, and their evolutionary history. Lagomorphs are divided into 2 basic groups Lagomorphs are a group of mammals that includes two basic groups, the pikas, and the hares and rabbits. Pikas are small, rodent-like mammals with short limbs and rounded ears. When they crouch down, they have a compact, almost egg-shaped profile. Pikas prefer cold climates throughout Asia, North America and Europe. They often inhabit mountainous landscapes. Hares and rabbits are small to medium-sized mammals that have short tails, long ears, and long hind legs. They have fur on the soles of their feet, a characteristic that gives them added traction when running. Hares and rabbits have acute hearing and good night vision, both adaptations to the crepuscular and nocturnal lifestyles of many of the species in this group. There are about 80 species of lagomorphs There are about 50 species of hares and rabbits. Well-known species include the European hare, snowshoe hare, Arctic hare and eastern cottontail. There are 30 species of pikas. Today, pikas are less diverse than they were during the Miocene. Lagomorphs were once thought to be a group of rodents Lagomorphs were once classified as a subgroup of rodents due to similarities in physical appearance, the arrangement of teeth and their vegetarian diet. But today, scientists believe that most similarities between rodents and lagomorphs are the result of convergent evolution and not due to shared ancestry. For this reason, lagomorphs have been promoted within the mammalian classification tree and now ran astride rodents as an order in their own right. Lagomorphs are among the most intensely hunted of any animal group Lagomorphs serve as prey for a wide variety of predator species around the world. They are hunted carnivores (such as bobcats, mountain lions, foxes, coyotes) and predatory birds (such as eagles, hawks, and owls). Lagomorphs are also hunted by humans for sport. Lagomorphs have adaptations that enable them to elude predators Lagomorphs have large eyes that are positioned on either side of their head, giving them a field of vision that encircles them completely. This gives lagomorphs a better chance of spotting approaching predators since they have no blind spots. Additionally, many lagomorphs have long back legs (enabling them to run quickly) and claws and fur-covered feet (which give them good traction). These adaptations give lagomorphs a better chance of escaping predators that get too close for comfort. Lagomorphs are absent from only a few terrestrial regions throughout the world Lagomorphs inhabit a range that includes North America, Central America, parts of South America, Europe, Asia, Africa, Australia and New Zealand. In some parts of their range, especially islands, they were introduced by humans. Lagomorphs are absent from Antarctica, parts of South America, Indonesia, Madagascar, Iceland and parts of Greenland. Lagomorphs are herbivores Lagomorphs eat plants of various forms including grasses, fruits, seeds, herbs, buds, leaves and even bits of bark they strip off of deciduous and coniferous trees. They are also notorious for eating cultivated plants such as grains, cabbage, clover, and carrots. Since the plant foods they eat are nutrient-poor and difficult to digest, lagomorphs eat their droppings, thus causing the food material to pass through their digestive tract twice to maximize the number of nutrients they are able to extract. Lagomorphs have high reproductive rates Reproductive rates for lagomorphs are generally quite high. This offsets the high mortality rates they often face due to harsh environments, disease, and intense predation. The largest lagomorph is the European hare The European hare is the largest of all lagomorphs, reaching weights of between 3 and 6.5 pounds and lengths of more than 25 inches. The smallest lagomorphs are the pikas Pikas include the smallest of all lagomorphs. Pikas generally weigh between 3.5 and 14 ounces and measure between 6 and 9 inches long.

Giant Beaver (Castoroides) - Facts and Figures

Giant Beaver (Castoroides) - Facts and Figures Name:Â  Giant Beaver; also known as Castoroides (Greek for of the beaver family); pronounced CASS-tore-OY-deez Habitat:Â  Woodlands of North America Historical Epoch:Â  Late Pliocene-Modern (3 million-10,000 years ago) Size and Weight:Â  About eight feet long and 200 pounds Diet:Â  Plants Distinguishing Characteristics: Large size; narrow tail; six-inch-long incisors About the Giant Beaver (Castoroides) It sounds like the punchline to a prehistoric joke: an eight-foot-long, 200-pound beaver with six-inch-long incisors, a narrow tail, and long, shaggy hair. But Castoroides, also known as the Giant Beaver, really existed, and it fit right in with the other plus-sized megafauna of its late Pliocene and Pleistocene ecosystem. Like modern beavers, the Giant Beaver probably led a partially aquatic lifestyleespecially since it was too big and bulky to move about sleekly on land, where it would have made a tasty meal for a hungry Saber-Tooth Tiger. (By the way, other than both being mammals, the Giant Beaver was completely unrelated to the beaver-like Castorocauda, which lived during the late Jurassic period.) The question everyone asks is: did the Giant Beaver build equally giant dams? Sadly, if it did, no evidence of these gigantic construction projects has been preserved into modern times, though some enthusiasts point to a four-foot-high dam in Ohio (which may well have been made by another animal, or be a natural formation). Like the other mammalian megafauna of the last Ice Age, the extinction of the Giant Beaver was hastened by the early human settlers of North America, who may have valued this shaggy beast for its fur as well as its meat.

Answer 5 Questions Regarding Business, and Marketing Essay

Answer 5 Questions Regarding Business, and Marketing - Essay Example Franchisees privately own three-quarters of this corporation. The major requirement necessary for the purchase of a franchise include availability of funds to facilitate running of operations; possession of essential management expertise as required by the franchise; and ability to satisfy legal requirements mandated by the selected business. (3, 1) Foreign ownership of franchises is usually subjected to a number of legal restrictions. This varies among countries. Moreover, it is usually faced with a number of setbacks, a useful example being language barrier (1,1; 2, 1) Advertisement is an industry that cannot be separated from the media, production and business sector. Advertisement restrictions are limitations meant to control what is advertised through the media sector. These restrictions limit advertisement by preventing marketing of certain commodity. Consequently, this leads to reduced net income of respective businesses. (1, 1; 5, 1) Advertisement restriction differs among countries. A useful example is Brazil. The advertisement of some products (cigarettes and alcoholic drinks) is only allowed from 2100 hours to 0600 hours. Thus, businesses have been unable to achieve their economic goals on time. Reason being, by restricting advertisement consumer interest and awareness regarding the products will be low. In addition, the market promotion strategy will be negatively affected. Thus, businesses will opt for regions with less restriction. (5, 1) American fast food, music and movies are popular around the world with little production adaptation. U.S retailers, banks and the beer firms have had to make major adaptation to their products. Why? Provide examples. Adaptation involves changes in methods of business. It may include price promotions; and changing the product to make fit the preference of the consumers. Adaptation occurs if a single or more factors are changed. It occurs for attaining competitive gains in the markets.

Best Practices in Managing the Human Factors of HR Management Literature Review Essay Example for Free

Best Practices in Managing the Human Factors of HR Management Literature Review Essay Human Resource Management is one of the most significant functions in an enterprise. However, there are different factors that are impacting on HRM. Human Factors has its origins in the Industrial Revolution and emerged as a full-fledged discipline during World War II. It was recognized that aircraft cockpit design needed to consider the human interface for controls and displays. Design Engineers were focused on the technology while Industrial Psychologists worked to optimize the interface. In some cases, Human Factors design can affect bottom-line profitability or can be a life and death matter, e. g. , you dont want to push the wrong button or mistake meters for kilometers in a spacecraft. Companies came to realize that a products success is dependent upon good Human Factors design. Human Factors are very important for the successful operation of the company. The term human factors is to a large extent synonymous with the term ergonomics Human Factors Integration Research with Defense Technology Center is Human Factors Integration is the process adopted by a number of key industries (notably defense like United Defense and hazardous industries like oil gas like Shell) in Europe to integrate human factors elements into the systems engineering process. Although each industry has a slightly different domain the underlying approach is the same. HFI undertakes this by conducting a formal process that identifies and reconciles human related issues. These issues are split for convenience into domains. Manpower The number of military and civilian personnel required and potentially available to operate, maintain, sustain and provide training for systems Page 2 Personnel The cognitive and physical capabilities required to be able to train for, operate, maintain and sustain systems. Training – The instruction or education, and on-the-job or unit training required to provide personnel their essential job skills, knowledge, values and attributes. Human Factors Engineering The integration of human characteristics into system definition, design, development, and evaluation to optimize human-machine performance under operational conditions. Health Hazard Assessment Short or long term hazards to health occurring as a result of normal operation of the system. System Safety – Safety risks occurring when the system is functioning in an abnormal manner. Strengths: Indentifying the Problem, Evaluation and solving issues Weakness: Psychological Human Factors are not treated. Motorola’s Human Factors Engineering One of the best Practice in Managing Human Resource is HFE, Firstly implemented by Motorola, USA in 1984 is considered as the best for employees. In Research with HFE, Motorola is commonly thought of as how companies design tasks and work areas to maximize the efficiency and quality of their employees work. However, Motorola HFE comes into everything which involves people. Work systems, sports and leisure, health and safety should all embody Human Factors principles if well designed. Strengths: Employee Determination at work, Safety Health and Low Stress methods. Weakness: More importance to Leisure time and found some Low Production. Page 3 Encourage Employee Development Growth of a company is closely linked to employee development within the organization where each employee plays a vital role in the success of the company. Employee growth has direct and indirect benefits. More knowledgeable, skilled and capable employees directly impact your company’s ability to satisfy customers, resolve problems and crises, and adapt to changing market conditions. Paying for an employee’s continuing professional education, for example, can help your company gain expertise in new technologies and markets, which can save you money in the long run. This type of practice is found in Coco Cola, where are often send to Trainings on different process. Strengths: Motivational to Employee and Long Retention periods. Weakness: Cost effective and Time Taking Process. Work Life Balance The term â€Å"work life balance† was coined in 1986 in response to the rising trend Human Factors in Development of the Company. The employee Psychological benefits are taken into consideration with many instructions like Stay positive, stay in control, Stay healthy, Divide and de-clutter, Keep stress under control and other safety measures. This helps the companies to maintain good relations with the employees and make them as the best factor of production. In Research with General Electric which follows Work Life Balance as a practice to develop Human Factors. Strengths: High Production Facility, Long Retention and Safe Employee and Company Relations. Weakness: Only limited to Companies with Large Scale of Production Facilities. Page 4 Corporate Mentoring Programs Corporate Mentoring Programs are like teaching classes where employees are motivated to the work and work environment, making employee coordinated towards work. Therefore, companies have started to place greater emphasis on personal attributes while selecting and developing staff. This brings a number of benefits to the business, not the least of which is a cohesive team. On going development of employee potential is critical for business success. Corporate mentoring programs are effective in quickly ramping up employee performance because they facilitate the transfer of business knowledge in a way that is not quite possible in regular training. Strengths: Every Effective Approach in Developing Human Factors, Human Psychological Advantage and Growth Oriented. Weakness: Very Systematic Approach. Metrics to Evaluate the Practices Human Factors Integration (HFI) implemented by Defense sectors is only related to Large Scale industries although it has all the factors of Human Factors. Key Performance Indicator of Human Factor Integration(HFI) is the Objective oriented and Specific Tasking. Motorola’s Human Factors Engineering is also related to tasking and other relations, not dealing with the Psychological factors of the Employees. Encourage Employee Development is training method to make them work in stress and problems, No personal and physical importance is not given to the employees. During this Research we found that the best Practice that develops the Human Factors in the company is Corporate Mentoring Programs, where the employees are motivated on the work and provide various benefits including safety and stress free work Page 5 environment. Research with Minnesota University, I found that more than 80% of the companies in United States uses this Corporate Mentoring Programs.

Government Intrusion and Civil Liberties Essay -- Government

Most people have either read or heard of the book 1984 in some point in their high school career. Some may see it as just fictional literature that we learn in English class, but it could become seeing as to how our government is handling national security. In 1984, the author, George Orwell talks about a society in which one group of people runs society and everyone is under surveillance. This was something that people in the 1980s would not think possible, so how could Orwell have thought of this plot when writing the book during the 1940s? It could have been due to the progress in technology such as radio, film, television. The fear of government interference could have also been produced because World War II was present the time 1984 was created, from which Orwell twists in his book. What is even more interesting is that the Cold War is somehow described in 1984 and it pretty much became true. With the Cold War having taken place, U.S. citizens were worried that people am ong them could be a Communist; the enemy of the U.S. and capitalism. Because of their fear, people started to accuse one another of being communists, which led to them being imprisoned with little and what was, invalid evidence. This is now referred to as the ‘Red Scare’ where ‘Red’ symbolized Communism. After this so called war, there was a time of peace where the likelihood of there being another ‘Red Scare’ was very unlikely, until the unforgettable date, September 11, 2001, or often referred to as 9/11 where the government’s fear of terrorist presence begun.

Pestel Analysis of Burger King Essay

Environmental factors may contribute to the increasing prevalence of obesity, especially in black and low-income populations. In this paper, the geographic distribution of fast food restaurants is examined relative to neighborhood sociodemographics. Methods Using geographic information system software, all fast-food restaurants within the city limits of New Orleans, Louisiana, in 2001 were mapped. Buffers around census tracts were generated to simulate 1-mile and 0.5-mile â€Å"shopping areas† around and including each tract, and fast food restaurant density (number of restaurants per square mile) was calculated for each area. Using multiple regression, the geographic association between fast food restaurant density and black and low-income neighborhoods was assessed, while controlling for environmental confounders that might also influence the placement of restaurants (commercial activity, presence of major highways, and median home values). Results In 156 census tracts, a total of 155 fast food restaurants were identified. In the regression analysis that included the environmental confounders, fast-food restaurant density in shopping areas with 1-mile buffers was independently correlated with median household income and percent of black residents in the census tract. Similar results were found for shopping areas with 0.5-mile buffers. Predominantly black neighborhoods have 2.4 fast-food restaurants per square mile compared to 1.5 restaurants in predominantly white neighborhoods. Conclusions The link between fast food restaurants and black and low-income neighborhoods may contribute to the understanding of environmental causes of the obesity epidemic in these populations.

My School and Its Teaching Environment Essay

In my school, the teaching environment is very good for teachers and especially for the students. When you see the school, at first you will say â€Å" wow! Excellent facilities, playground for teachers and students, cozy cafeteria and a library with good ambience where you can study comfortably, all classrooms are air-conditioned, enough computers for students with the ratio of 1:1 with internet connection. Each student has internet password as well as the teachers and staffs. The school used Fiber Optic line for internet (this is part of my work where I maintain the internet connection for the whole school). In my first 2 years in this school, I was assigned in Middle School but this year I was transferred to Elementary Department as Head of Information Technology including repair and maintenance with 24 hours a week teaching load for students from grade 1 to 5 (too many works hehehe) forgot to mention at the same time I am one of the administrators for TOEFL (Test of English as Foreign Language) exam. Every year, especially year-end everybody is waiting for contract renewal, thinking who will be renewed and who will say goodbye. If someone will leave then we are thinking who will replace them. Why? Simply because we are waiting for another teacher who will introduce another technique in teaching or I simply put it this way for new teachers: If you can’t beat us, then join us†¦ hahahahaha! The Culture of this country (Thailand) is almost the same in our country (Philippines) when it comes to being hospitable and respecting other people. They have great respect with each other especially with the old ones. In my school, students develop respect and tolerance for all others, regardless of religion, race, or class. One of the most distinctive Thai customs is the wai. Showing greeting, farewell, or acknowledgement, it comes in several forms reflecting the relative status of those involved. Generally, the salutation involves a prayer-like gesture with the hands, and it also may include a slight bow of the head. This salutation is often accompanied by a serene smile symbolizing a welcoming disposition and a pleasant attitude. Thailand is often referred to as the â€Å"Land of Smiles† in tourist brochures. There are a number of Thai customs relating to the special status of monks in Thai society. Due to religious discipline, Thai monks are forbidden physical contact with women. Women are therefore expected to make way for passing monks to ensure that accidental contact does not occur. A notable social norm holds that touching someone on the head may be considered rude. Pointing at or touching something with the feet is also considered rude. In every activity we do whether it is curricular or extra-curricular, we always align it to their culture if this is acceptable or not. But since we do have native speakers, sometimes they don’t even care about the culture. They always say that â€Å"Everybody knows what Thailand is† (for them most of the Thai women are slut, people have already changed) but somehow these native speakers must learn how to adapt into this environment. Yes, maybe that is their perception in this county and they forgot that they are Teachers. Teachers should give moral values and educate them in proper way. One of the problems of this school and even this country, discrimination between Asian and English Native speakers are very obvious. Sometimes they just use these native speakers as front of the school but most of the teachers are Asian who are more dedicated to work and yet under paid compared to these native teachers. Our administrators are composed of Executive Director (owner), Associate Executive Director, Business Director, Curriculum Coordinator, Student Support Coordinator, Principals and PTA. PTA in this school is very active in every. If we have activities either curricular or extra-curricular, the parents are always there to support us. Just to name a few for extra-curricular activities: 1. Students vs Teachers and Staff football match 2. Teachers and Staff vs Parents football match 3. Teachers, Staff and Parents vs Military Personnel Football Match 4. Teachers and Staff Football Match These are some interesting extra-curricular activities that everybody loves to see. Because even the owner of the school also plays in this event. We do have some curricular activities such as: 1. Debate in English(I’m the coach) 2. Debate in Thai 3. Public Speaking 4. Spelling 5. Story Telling 6. Quiz bee

Free Essays on China as Most Favored Nation

China as Most Favored Nation Essay written by: TapOut136 What is the debate on weather or not China should retain favored-nation trading status all about? Is it really a decision on what is best economically for the United States, and China. Or is it: the issue of Chinese human rights violations and the fact that if the United States where to revoke the favored nation status of China it would have a profound negative impact on the U.S. economy alone. (+)Most-favored-nation trade status started in the United States as a version of the European preferential trade system. The Carter Administration first granted most-favored-nation trading status to China in 1980, following the historic efforts of President Nixon during the 1970’s to restore diplomatic ties. Historically, a significant difference existed between the unconditional most-favored-nation clause in European trade law and the American version of conditional most-favored-nation. Under unconditional most-favored-nation status, one country's extension of tariff concessions guarantees the same concessions to all nations associated with it through commercial treaties. American conditional most-favored-nation status provided treaty signatories only the opportunity to negotiate most-favored-nation status when most-favored-nation status was extended to another trading partner. Thus meaning that the United States gives significant economic advantages to one nation in the form of most-favored-nation trading status. Under the Trade Act of 1974, most-favored-nation status could only be granted to China through a Sino-American bilateral commercial agreement and satisfaction of the Jackson-Vanik Amendment requirements.

The Four Cerebral Cortex Lobes of the Brain

The Four Cerebral Cortex Lobes of the Brain The cerebral cortex is the layer of the brain often referred to as gray matter. The cortex (thin layer of tissue) is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white. The cortex covers the outer portion (1.5mm to 5mm) of the cerebrum and cerebellum. The cerebral cortex is divided into four lobes. Each of these lobes is found in both the right and left hemispheres of the brain. The cortex encompasses about two-thirds of the brain mass and lies over and around most of the structures of the brain. It is the most highly developed part of the human brain and is responsible for thinking, perceiving, producing and understanding language. The cerebral cortex is also the most recent structure in the history of brain evolution. Cerebral Cortex Lobes Function Most of the actual information processing in the brain takes place in the cerebral cortex. The cerebral cortex is located in the division of the brain known as the forebrain. It is divided into four lobes that each have a specific function. For example, there are specific areas involved in movement and sensory processes (vision, hearing,  somatosensory perception (touch), and olfaction). Other areas are critical for thinking and reasoning. Although many functions, such as touch perception, are found in both the right and left cerebral hemispheres, some functions are found in only one cerebral hemisphere. For example, in most people, language processing abilities are found in the left hemisphere. Four Cerebral Cortex Lobes Parietal Lobes: These lobes are positioned posteriorly to the frontal lobes and above the occipital lobes. They are involved in receiving and processing of sensory information. The somatosensory cortex is found within the parietal lobes and is essential for processing touch sensations.Frontal Lobes: These lobes are positioned at the front-most region of the cerebral cortex. They are involved with movement, decision-making, problem-solving, and planning. The right frontal lobe controls activity on the left side of the body and the left frontal lobe controls activity on the right side.Occipital Lobes: Located just below the parietal lobes, the occipital lobes are the main center for visual processing. The visual information is sent to the parietal lobes and temporal lobes for further processing.Temporal Lobes: These lobes are located directly below the frontal and parietal lobes. They are involved with memory, emotion, hearing, and language. Structures of the limbic system, including t he olfactory cortex, amygdala, and the hippocampus are located within the temporal lobes. In summary, the cerebral cortex is divided into four lobes that are responsible for processing and interpreting input from various sources and maintaining cognitive function. Sensory functions interpreted by the cerebral cortex include hearing, touch, and vision. Cognitive functions include thinking, perceiving, and understanding language. Divisions of the Brain Forebrain - encompasses the cerebral cortex and brain lobes.Midbrain - connects the forebrain to the hindbrain.Hindbrain - regulates autonomic functions and coordinates movement.

Plastic Pollution in oceans (marine Life) due to human activity Term Paper

Plastic Pollution in oceans (marine Life) due to human activity. Research - Term Paper Example The pollution caused due to plastic is increasing at a very fast pace and that is because the demand for products produced through plastic is increasing day by day. According to Andrady 80 million tons of plastic and plastic waste is found in the marine regions throughout the globe (Andrady 1). There are various causes as well as harmful effects of plastic pollution in marine life, but at the same time several steps can be taken to solve the issue of oceanic regions being polluted due to plastic. There are various causes due to which plastic pollution in oceans is experienced. One of these causes is that plastic enters the oceans and water in an indirect manner. There are many ways through which plastic can enter the water in an indirect manner. One of the most common ways is that plastic based garbage is left on the coastal areas by those individuals who are recognized as beachgoers. The problem is that water reaches the coastal areas and absorbs the plastic waste and travels back into the sea area along with plastic products. Another method through which plastic waste reaches the oceans is recognized as land runoff. This event takes place when huge amount of rain water moves plastic waste from the land area to the sea area. A third method through which plastic debris reaches the ocean is through the route of sewage. This means that plastic waste travels to the oceans when that waste is dumped in sewage and rivers which carries the waste to the sea. A fourth method through which plastic waste reaches oceans is through the heavy winds that blow plastic debris from land area to oceans (Andrady 1). According to Andrady, around 80% of the plastic waste or debris that is found in the oceans is caused due to the plastic waste that enters the oceans through indirect means such as littering of the coastal regions by those who are beachgoers (Andrady 1). Other than indirect transfer of plastic

Discussion - Essay Example First, Agile is found to be simpler and easier to follow. The phases of envision, speculate, explore, adapt and close flow better in a management process. This is different in the triangle where interconnection of tasks may result in complexities. Secondly, the triangle represents a correlation between time, cost and output as opposed to the Agile Framework which is more of a process-based framework.
