Biogeography The Study of Global Species Distribution

Biogeography is a branch of geography that studies the past and present distribution of the worlds many animal and plant species and is usually considered to be a part of physical geography as it often relates to the examination of the physical environment and how it affected species and shaped their distribution across the world. As such, biogeography also includes the study of the worlds biomes and taxonomy—the naming of species—and has strong ties to biology, ecology, evolution studies, climatology, and soil science as they relate to animal populations and the factors that allow them to flourish in particular regions of the globe. The field of biogeography can further be broken down into specific studies related to animal populations include historical, ecological, and conservation biogeography and include both phytogeography (the past and present distribution of plants) and zoogeography (the past and present distribution of animal species). History of Biogeography The study of biogeography gained popularity with the work of Alfred Russel Wallace in the mid-to-late 19th Century. Wallace, originally from England, was a naturalist, explorer, geographer, anthropologist, and biologist who first extensively studied the Amazon River and then the Malay Archipelago (the islands located between the mainland of Southeast Asia and Australia). During his time in the Malay Archipelago, Wallace examined the flora and fauna and came up with the Wallace Line—a line that divides the distribution of animals in Indonesia into different regions according to the climates and conditions of those regions and their inhabitants proximity to Asian and Australian wildlife. Those closer to Asia were said to be more related to Asian animals while those close to Australia were more related to the Australian animals. Because of his extensive early research, Wallace is often called the Father of Biogeography. Following Wallace were a number of other biogeographers who also studied the distribution of species, and most of those researchers looked at history for explanations, thus making it a descriptive field. In 1967 though, Robert MacArthur and E.O. Wilson published The Theory of Island Biogeography. Their book changed the way biogeographers looked at species and made the study of the environmental features of that time important to understanding their spatial patterns. As a result, island biogeography and the fragmentation of habitats caused by islands became popular fields of study as it was easier to explain plant and animal patterns on the microcosms developed on isolated islands. The study of habitat fragmentation in biogeography then led to the development of conservation biology and landscape ecology. Historical Biography Today, biogeography is broken into three main fields of study: historical biogeography, ecological biogeography, and conservation biogeography. Each field, however, looks at phytogeography (the past and present distribution of plants) and zoogeography (the past and present distribution of animals). Historical biogeography is called paleobiogeography and studies the past distributions of species. It looks at their evolutionary history and things like past climate change to determine why a certain species may have developed in a particular area. For example, the historical approach would say there are more species in the tropics than at high latitudes because the tropics experienced less severe climate change during glacial periods which led to fewer extinctions and more stable populations over time. The branch of historical biogeography is called paleobiogeography because it often includes paleogeographic ideas—most notably plate tectonics. This type of research uses fossils to show the movement of species across space via moving continental plates. Paleobiogeography also takes varying climate as a result of the physical land being in different places into account for the presence of different plants and animals. Ecological Biogeography Ecological biogeography looks at the current factors responsible for the distribution of plants and animals, and the most common fields of research within ecological biogeography are climatic equability, primary productivity, and habitat heterogeneity. Climatic equability looks at the variation between daily and annual temperatures as it is harder to survive in areas with high variation between day and night and seasonal temperatures. Because of this, there are fewer species at high latitudes because more adaptations are needed to be able to survive there. In contrast, the tropics have a steadier climate with fewer variations in temperature. This means plants do not need to spend their energy on being dormant and then regenerating their leaves or flowers, they don’t need a flowering season, and they do not need to adapt to extreme hot or cold conditions. Primary productivity looks at the evapotranspiration rates of plants. Where evapotranspiration is high  and so is plant growth. Therefore, areas like the tropics that are warm and moist foster plant transpiration allowing more plants to grow there. In high latitudes, it is simply too cold for the atmosphere to hold enough water vapor to produce high rates of evapotranspiration and there are fewer plants present. Conservation Biogeography In recent years, scientists and nature enthusiasts alike have further expanded the field of biogeography to include conservation biogeography—the protection or restoration of nature and its flora and fauna, whose devastation is often caused by human interference in the natural cycle. Scientists in the field of conservation biogeography study ways in which humans can help restore the natural order of plant and animal life in a region. Often times this includes reintegration of species into areas zoned for commercial and residential use by establishing public parks and nature preserves at the edges of cities. Biogeography is important as a branch of geography that sheds light on the natural habitats around the world. It is also essential in understanding why species are in their present locations and in developing protecting the worlds natural habitats.

The Disease Of Alzheimer s Disease - 2327 Words

Introduction Alzheimer’s disease (AD) a neurodegenerative disease that affects memory, thinking and behavior and is the sixth leading cause of death in the United States. Approximately 1 in 4 people that reach the age 80-84 are expected to develop Alzheimer’s, and it is expected to affect 30-40 million people worldwide by the year 2050 (Steele, et. al, 2006). This disease is not a normal part of aging. However, the risk of onset increases with age, as well as underlying inflammatory processes. Alzheimer’s is a progressive disease with the most common reported system being difficulty recalling newly learned information. As the disease progresses, an affected individual may experience disorientation, mood changes, behavior changes, confusion, memory loss, suspicion about family and friends, walking difficulty and an inability to carry on a conversation. Simultaneously, the brain of the affected individual develops increasing amounts of plaque (deposits of the protein beta-amylo id that form between neurons) and tangles (twisted fibers called tau that build inside neurons). These deposits interfere with neuron conduction and may lead to neuronal apoptosis. It is widely accepted that omega-3 fatty acids and brain health have a positive relationship. Therefore, we wanted to analyze a diet that was high in this essential nutrient to determine its’ relationship with Alzheimer’s disease prevention.

Effect of Culture on Marketing-Free-Samples-Myassignmenthelp.com

Question: Discuss about the various factors and issues which affect International marketing. Answer: Introduction International marketing is altogether different from domestic marketing. There is a host of issues which affect marketing practices by companies in international marketing which a business need not manage when promoting in their own nation. The main issues which company constantly faces are cultural issue due to which policies and practices need to be framed keeping in mind the perquisites of the nation. Key issues in international marketing Language: The issue of language creates huge problems for international marketing. The language is considered as a significant element in culture. The companies should be aware of the difference in regional languages before doing any marketing practices. For instance: one same word has a different meaning in different languages[1]. This is to be given main consideration especially when doing verbal marketing. Like in some countries people shake head to convey yes but in some countries shaking head is taken as opposite in the context of language. Terpstra, Vern, James Foley, and Ravi Sarathy argued that there have stayed some awkward errors in the worldwide promotion which did not help corporations sell their merchandise[2]. The latest instance nobody at General Motors understood the interpretation for the name of their car, the "Nova" which signified "it won't go" in South America. According to Majaro, Gerber ltd also utilized a similar packaging with the charming little child on it they had utilized for packaging its infant nourishment in Africa; they didn't understand that with the high ignorance rate in Africa that it was normal for food packaging to show a photo of the ingredients inside. Demographics: The span of the populace is a critical determinant of interest for some items. There are nations with just a couple of lakh of individuals from one viewpoint and those with several million then again. As per a World Development Report, there were 58 nations with a population of lesser than one million[3]. And these nations are less attractive to business ventures. Poor nations with little population are by and large not appealing for business. Paul also stated that even nations may hold out open doors for some organizations. As these business sectors may not be of significant importance for big organizations, little companies can discover promising specialties in these business sectors. Age and different demographic assume a key part in global promotion similarly as they do in national marketing; organizations need to give careful consideration to them. The organization is most likely not going to need to market laptops to senior nationals in an underdeveloped nation where there is no access to the internet and where an extensive level of the residents more than 60 are computer ignorant[4]. This represents the significance of understanding age and different demographics on a potential nation that should be targeted for products or services to since they are both strong and utilized as a part of deciding on advertising selection. Consumer habits: Culture and personality combine to shape consumer behavior in every particular region of the world or country. Regardless of globalization, individuals from various countries keep on having their own particular unique habits and tastes, their qualities and standards established in their national societies[5]. It is also a fact that there is no experimental proof to demonstrate homogenization of tastes or the presence of widespread price-minded of customer sections. Culture is vibrant and is continuously affected by variations in environment in social establishments and persons own esteems[6]. The mutual cultural values need business to fit according to the social and economic reward opportunities to which persons should adjust and in which they invest the majority of their energy (relatives, universities, societies, and many more) to work effortlessly and successfully. Individuals belonging to the particular nation with a specific national culture are liable to the contentions and co mpatibilities, which they follow. According to Ilkka A. Ronkainen it is difficult for organization to fit in any culture with ease as diverse culture imposes many restrictions on company to explore its operations. Religion: Religion affects international marketing that is found in a culture's esteems and states of mind toward enterprise, consumption, and social association. The effect will fluctuate contingent upon the quality of the overwhelming religious tents. While religion's effect might be very twisting in Northern Europe, its effect in nations where Islam religion is on the rise might be significant. Al-Hyari Khalil also argued that religion gives the premise to cultural similarities under shared opinions and conduct. The effect of these likenesses will be evaluated regarding the overwhelming religions of the world Christianity, Islam, Hinduism, Buddhism, and Confucianism. The part of ladies in business is attached to religion, particularly in the Middle East where they are not ready to work as they would in the West[7]. The impacts of this are various for instance a firm might be constrained in its utilization of female directors or workforce in these territories and ladies' part as purchasers and influencers in the utilization procedure might be unique. Aside from food purchases men make the last buy decisions. Manners and customs: Change happening in conduct and traditions should be deliberately observed, exclusively in cases that appear to show a narrowing of social contracts between individuals. Like McDonald's and Coke have met with progress far and wide, yet this does not imply that the world is getting to be westernized[8]. Modernization and Westernization are not in the slightest degree the same as can be found in Saudi Arabia. Americans frequently interpret delay and silent as negative symbols. Package sizes and marks must be adjusted in numerous nations to suit the requirements of the specific culture. In Mexico Campbell's pitches soup in jars sufficiently vast to serve four or five since families are mostly big. In Britain where buyers are more acclimated to prepare to serve soups, Campbell's prints one can make two on its consolidated soup names to guarantee that customers see how to utilize it. Erdener, Kaynak, and Herbig Paul also argued that manners and customs leave a huge effect on the company values and cultures it follows in its origin nation. This creates difficulty for company to survive successfully in international market. Conclusion As observed from the above report a company in order to promote product or service internationally, there are numerous cultural issues that company and marketing team must reflect before determining which nation or area it wants to sell products or amenities to. The issues like demographic, language, consumer behavior and much more can adversely affect a company existence if not considered properly during international marketing.

The Following Was Completed For A Political Thought And Theory Class I

The following was completed for a Political Thought and Theory Class in my Senior Year of Highschool..my grade was an 85 Montesquieu: Definition of Law Into the first three chapters of Book 1, The Spirit of Laws, Montesquieu condensed a lifetime of thinking, not so much on law as what law is, (after all, the work by Montesquieu is entitled The Spirit of Laws, not The Laws of the Spirit). The definition of law provided to us by Montesquieu can be most clearly identified as a series of relationships which are derived from the nature of things; relationships varying not only among human beings, but animals and thought. Background: Montesquieu, Charles-Louis de Secondatbaron de la Br?de et de Born January 18, 1689, Montesquieu (Caption 1-1) belonged to an old family of modest wealth that had been ennobled in the 16th century for services to the crown. Charles-Louis studied at the faculty of law at the University of Bordeaux, was graduated, and ventured out for experience in law. He married Jeanne de Lartique and through marriage he became socially and financially secure. He wrote many works pertaining to the lawfield (Encarta). Montesquieu's Definitions of Law "Laws, in their most general signification, are the necessary relations arising from the nature of things." (Spirit) Montesquieu in the first book would seem to be collating all that has been said on the law into some complex equation, eliminating the common and arriving at some simple solution. Thus, laws in the most general sense are the relationships between things (all things) as the nature of things shows: the nature of things seen, heard, and read. God isn't seen nor heard, or read; still, he must have his place, but not first in the order of the nature of things (Catholic). "There is, then, a prime reason; and laws are the relations subsisting between it and different beings, and the relations of these to one another." (Spirit) But we have overlooked a key word kept by Montesquieu in his most concentrated definition: laws are not only relationships, they are necessary relationships. Here grows a somewhat ambiguous question. Why are they necessary? They are not necessary due to a decree of some sort, but become natural; thus the term "Prime Reason. (Loy 89)" "God is related to the universe, as Creator and Preserver; the laws by which He created all things are those by which He preserves them. He acts according to these rules, because He knows them; He knows them, because He made them; and He made them, because they are in relation to His wisdom and power." (Spirit) It is true that Montesquieu seems to waver between "natural law" and"laws of nature" as expressions. It is also true that he defines laws of nature as those that derive solely from our beings (Loy 90). "By the allurement of pleasure they preserve the individual, and by the same allurement they preserve their species. They have natural laws, because they are united by sensation; positive laws they have none, because they are not connected by knowledge." (Spirit) Animals however, are without knowledge but have some natural laws. Although Montesquieu does spare us the seventeenth-century discussion of pre-social man, he has not escaped certain confusions in regards to human reason and Prime Reason (Chan). "Before there were intelligent beings, laws were possible; they had therefore possible relations, and consequently possible laws. Before laws were made, there were relations of possible justice. To say that there is nothing just or unjust but what is commanded or forbidden by positive laws, is the same as saying that before the describing of a circle all the radii were not equal." (Spirit) It is also in his discussion of natural law that Montesquieu comes to the conclusion that after God comes first a state of peace. For Montesquieu, peace is the first law of nature. Following natural laws are nourishment, sex, and society (Chan). "But the intelligent world is far from being so well governed as the physical. For though the former has also its laws, which of their own nature are invariable, it does not conform to them so exactly as the physical world." (Spirit) Once the natural law is done with (and Montesquieu started there for many reasons), one is on relatively clearer, emperic grounds with the positive laws. International law, political law, civil law: nothing in Montesquieu's estimation could be more easily grasped from looking at man's past. When Montesquieu makes his famous statement that law is human reason, one takes note he is writing under the heading "positive law. (Loy 91)" "Law, in general,
