Sierra Nevada Foothills Ecosystem The foothills of the Sierra Nevada are only a small section of the mountain range, encompassing the East and West slopes of the ranges in elevation from around 1,000 to 3,000 feet. The foothills are known as a biotic zone, one of five biotic zones, or ten if the person studying wishes to separate the Eastern side of the range from the Western side of the range. For our purposes, we will be including the Eastern and Western sides of the mountain range together as all being foothill zones. There are different types of species in the foothills of the Sierra Nevada; the producers, the consumers, and the decomposers. The Sierra Nevada Mountain Range’s foothills are at a low enough elevation that plant and animal life is adapted to hot, dry summers with very little or no snow in the winters. This type of dry climate leads to a lot of shrubbery and trees, which means there will be a large population of small animals and birds that will seek shelter in the shrubs and tree branches, as well as the larger animals that will feed on the plants and smaller animals. The plants that are typical to the foothills of the Sierra Nevada Mountain Range are numerous, but the most notable are the chamise, ceanothus, manzanita, Blue oak tree, Interior Live oak tree, and the Gray pine tree (Encyclopedia Americana, 2006). Chamise belongs to the rose family, and is a very dense flowering shrub that can grow up to 12 feet tall (Charters, M, 2010). Ceanothus belongs to the lilac family, and is often called the California Lilac (Schaffner, B., 2010). Ceanothus is a dense flowering shrub that is eaten by many of the animals as the leaves are very high in protein. Manzanita belongs to the evergreen family of shrubs and small trees, and is a dense…...

...Poverty in Sierra Leone Cassandra Jones Professor Tiffani Davis Sociology 300 September 1, 2012 Sierra Leone Sierra Leone is located on the West Coast of Africa near Guinea, Liberia, Guinea-Bissau and Gambia. Sierra Leone was founded in 1462, by a Portuguese explorer Pedro da Cintra sailing the West African coast. While there Pedo observed the mountains and thunderstorm that sounded like a lion’s roam in the distance. He therefore name Sierra Leone in his native language Sierra Leoa. The name was later changed in 1787 while under British rule Sierra Leone by English Jack Tars. The country is comprised over six million people of different ethnic backgrounds and religions that primarily speak English which is the official language. Many tribal languages are also used and in Freetown which is the capital of Sierra Leone, Krio is the second language spoken. It is a form of pigeon English encompassing tribal words. Sierra Leone also known as the Republic of Sierra Leone maintains a constitutional democracy which is composed of a President Ernest Bai KOROMA and legislative, judicial and executive branch. A constitutional democracy is a system of government based on popular sovereignty in which the structures, powers, and limits of government are set forth in a constitution. http://dictionary.reference.com/browse/constitutional+democracy.

...Ecosystem Structure, Function and Change SCI256 April 27, 20113 Ecosystem Structure, Function and Change Lake Tahoe is located in Sierra Nevada and is a freshwater lake over 1600 feet deep and one of the largest lakes in America. The lake is at the heart of a comprehensive ecosystem and home to a range of native species and contains a rich aquatic life. For example, the lake is home to redside dace, suckers and chub. “The ecosystem of the Lake Tahoe Basin has been dramatically altered since European settlers began to settle around the lake in the middle of the last century. Human disturbances, including introduced species, fire suppression, past overgrazing and logging, urbanization, roads, intensive recreational use, and air pollution, have affected not only the clarity of the lake, but the forest's ability to maintain the function, diversity, and resiliency of its components” (Tahoecam.com). Deforestation at the end of the 19th century, along with other issues such as drought, thinning and excessive rainfall, Lake Tahoe now has overcrowded and aged trees, yet with a 25% to 30% tree mortality which makes the danger of fires very severe (Tahoecam.com) Generally when it comes to the quality of the water in the lake, human activities of the last 130 years have done the most damage yet have acted as the biggest impetus to restore the water quality (Tahoecam.com). Furthermore the rate of algal growth has quadrupled in Lake Tahoe since 1959: “This increase in growth is......

...Discuss the possible effects of human interference on ecosystems. Identify links between altered nutrient cycling and the species composition/ structure of ecosystems. Ecosystem is a single working unit that consists of a group of interrelated organisms and their physical environment. It forms the basic functional unit of ecology (Boyle & Senior, 2008, p.602). Humans are part of the ecosystem where we play the role of consumers. Humans need a supply of mineral nutrients such as carbon, nitrogen and phosphorous which make up the carbohydrates, proteins, lipids and nucleic acids in our bodies. Minerals nutrients are recycled over and over again, passing between organisms in the ecosystem. The carbon, oxygen and nitrogen in our bodies could be part of the soil a year ago (Boyle & Senior, 2008, p6210). Instead of adapting to the environment like most other species do; we, humans change habitats and interfere with the ecosystem to suit ourselves as consumers. Altered nutrient cycles are one of the consequences of advancement of humans. Humans bring about environmental damages by influencing the carbon cycle in two ways. Firstly, forests removed for farming and housing have caused the depletion in plants and trees. Deforestation has reduced the numbers of trees and plants that absorb carbon dioxide through photosynthesis. The uptake of carbon dioxide by plants and oceans is not fast enough. As a result, the carbon dioxide level in the atmosphere increased by......

Nevada

...Nevada’s Future Nevada Nevada has come a long way. In the 1990s the population of Nevada was only 1,200,000 and now they have nearly doubled in size to 2,758,931 (US Census 2013). Nevada is well known throughout the world well I should say a certain city within in Nevada is well known, and that is Las Vegas. Many people have always wanted to come to Nevada but only for tourism not so much living. As you can see from the population, that has now changed. Jobs have grown in Nevada since all these casinos have now been opening up. Now that the casinos have helped build the population this has caused Nevada to have to grow in the local communities meaning more hospitals, retail stores, gas stations and so on. Nevada also seems to be very family oriented with the extreme amount of parks within the communities and also all of the amazing indoor play facilities for parents and their children. Nevada seems to revolve around its Gambling industry. I believe that this industry is what makes Nevada but there is also another. Will Nevada survive if the casinos go away and also mining comes to a stop? Casinos I believe that Nevada would fall dramatically if the casinos were to leave. They are a big impact on the local communities. People do not know that hotels like the MGM according to their annual 2012 report have spent $1 billion on supporting minority, women and disabled owned businesses (MGM 2011). MGM has also......

An Ecosystem

...miles southwest of Houston, Texas. It is a wonderful representative natural ecosystem that is receiving worthy considerations for native species preservation and management. There is no roadside sign to announce the Nash Prairie, no fence around more than 400 acres of tall grasses that have never been plowed. The grassland remained unplowed because of the farming methods. Cattle infrequently grazed on the property, and the landowners harvested hay once, maybe twice, a year and never in the same pattern, which allows plants time to regenerate. This has resulted in a rich and subtle ecosystem. Serious bird watchers, wildflower enthusiasts, and botanists tend to know about this place and its native grasses. Laura Huffman, Texas director of the Nature Conservancy (an environmental group) says that “this prairie is a beautiful representation of what Texas really looked like.” It is said to be a beauty in a haystack for many reasons. According to Wiley Plus (2009) publication, the structural and functional dynamics of this ecosystem is comprised of nonliving and living fundamentals. The nonliving part is the physical-chemical environment, including the local atmosphere, water, and mineral soil (on land) or other substrate (in water). The living part, called the ecological community, is the set of species interacting within the ecosystem. There are two basic kinds of processes that must occur in an ecosystem: a cycling of chemical elements and a flow of energy in order for it......

Throughout a time span you try and figure out the mysterious of why there are such beautiful beaches in certain areas and not all over the world. Well it is now time for us to uncover the mysterious of the beach creation of this world. We will be learning the structure, function, and the way it changes through the marvels of its beautiful and relaxing atmosphere. Each formation of water has its own purpose in life cycle. But the most interesting is the see through water at the beach, which are most common in the Caribbean areas and Gulf Coast. The reason that the water is so clear per the UCSB Scienceline article it is because the suspended or stirred up sediment and the living organic material, such as phytoplankton. Suspended sediments are when an over flow of water from a storm or waves carry into an ocean from a river. Organic material such as phytoplankton and zooplankton normally grow when light is made available and when the nutrients are made available from a storm. Phytoplankton is a plant organism that drifts in the ocean, and zooplankton is an animal organism the drifts/wanders in the ocean. It is harder for the water to get muddy in the Caribbean and Gulf Coast because it......

The Sierra Club

...The Sierra Club POL 310 Prof. Troy Tureau June 4, 2011 The Sierra Club is one of the largest, and most influential, grassroots environmental organizations in existence today. The Club was founded on May 24, 1892, in San Francisco, CA, by John Muir, who went on to become the Club’s first president. The Sierra Club has been committed to protecting wildlife, communities and, most importantly, this planet since its creation. The Sierra Club’s mission statement is: “To explore, enjoy, and protect the wild places of the earth; To practice and promote the responsible use of the earth's ecosystems and resources; To educate and enlist humanity to protect and restore the quality of the natural and human environment; and to use all lawful means to carry out these objectives”. The Sierra Club boasts hundreds of thousands of members in chapters located throughout the United States. The Board of Directors is made up of fifteen volunteer members, who are all also club members. Each year, five members are elected to three-year terms and every club member is eligible to vote. The president is elected annually and receives a small stipend. Generally, chapters are located state-wide except California, which has fourteen chapters. Membership in the club has different prices based on the level of membership chosen. Membership levels vary from basic, which costs fifteen dollars, to life membership, which is also broken up into two levels. The single life membership is $1000.00, while a......

Ecosystem

...What is an ecosystem? Well, an ecosystem includes all living things, such as animals and plants, and non-living things, such as the climate, soil and weather in a given area. Some examples of an ecosystem could be a desert, coral reef, or a rainforest. The ecosystem that has and will still to this day amaze me is the rainforest ecosystem. The rainforest can be characterized by its dense growth of trees in a very wet climate. There are tropical rainforests and temperate rainforests. The largest and in my opinion the most beautiful rainforest is the tropical. The tropical rainforest is home to more species of plants and animals than any of the other ecosystems combined. A tropical rainforest can be located near the equator. This type of rainforest is mainly in Brazil, but can also be found in Southeast Asia, the Pacific Islands, and West Africa. On the other hand, temperate rainforest can be found by the coast, the largest being by the Pacific coast of North America. The Daintree rainforest in Australia is by far the most interesting tropical rainforest. It is located north of Australia near Daintree, Queensland by the coast. This rainforest contains 30% of frog, marsupial and reptile species in Australia, and 65% of Australia's bat and butterfly species. It also contains 20 % of bird species in the country. In the rainforest there are both abiotic components and biotic components. Abiotic components are the nonliving things, such as ware, air, temperature, wind and the sun....

...SCI/ 256 4/14/2014 Week 2 Ecosystem Components Paper An ecosystem is a very complex set of relationships among our living resources, habitats, and residents of a selected area. Which consist of plants, animals, fish, trees, birds, water, microorganisms, soil, and people. Lake Mead National Recreation Area (NRA) located in Nevada provides spectacular scenic vistas of Lake Mead and rugged and isolated backcountry. Amazing and drastic physical features include deep canyons, colorful soils, sheer cliffs, distant mountain ranges, dry washes, the lakes, and rock formations and mosaics of different vegetation (National Park Service, 2012). In this essay I will be discussing the major structural and functional dynamics of Lake Mead National Recreation Area (NRA) on Roger Spring and Black Canyon Springs and how the human being have affected this ecosystem by interacting with its biogeochemical cycles. I will show how knowing the ecosystem structure and function could help in its management and restoration of the ecosystems as well. Black Canyon Spring is located downstream of Hoover Dam. Here, we can find springs of both the thermal (hot) and non-thermal (cold) variety with water temperatures ranging from about 55° to 136° Fahrenheit. Rogers Spring is located on “North Shore Complex” of the Lake Mead National Recreation Area. This area comprises of the terminal discharge areas for the regional carbonate-rock aquifer system from eastern Nevada (National Park Service,......

...Balancing Ecosystem University of Phoenix November 30th, 2015 Glimmerville City Council, I am writing this letter after it has come to my attention that your city is facing the same problem with the Grass Carp like the city of Sparksville. The problem with the grass carp is once they have been introduced they kill off the native species of our local waters. The purpose for the introduction of the grass carp is to remove the overabundance of indigenous aquatic plant life in particular habitats that have taken over due to fertilizer deposits making it to our community waterways thus, making survival hard for other inhabitants. In order to receive the optimal amount of benefits that the grass carp species has to offer, it must be released into a secure environment with no possibility of escape into other waterways. This species has found its way into many reservoirs, lakes, streams, and rivers in our community intentionally and/or by accident; either way it involves some degree of human error. Because the grass carp is native to Asia, it has no natural predators in North America so there is nothing to kill them in order to stop the production of more of them. Another major factor which adds to this problem is their life expectancy is quite a long time and weigh up to 100 pounds, maybe more. The large-mouth bass and a few other species of fish will eat them if they are small enough. The Grass carp are pushing out the other fish that fishermen want to catch. We had to...

...Ecosystem of the Mojave Desert Bio/101 March 5, 2012 Ecosystem of the Mojave Desert The Mojave Desert is 54,000 square miles of its own special brand of diversity; it is one desert - rather than a series of separate entities. By becoming aware of the combined identity, appreciation and better understanding of the issues that affect the Mojave Desert can occur on a holistic level. Generally, at the edges of the Mojave are areas where dominant plant and animal species change from one to another and both, to various degrees may be possibly found on the fringes of the other. The Mojave Desert ecosystem evolves from plants and animals which are resources within each other. Adaption to the rough temperatures and little water, these ecosystems finds many ways to survive. This ecosystem plays host to a wide variety of plants and animals living in an environment that humans may think are harsh conditions. Many animals get their energy by eating plants, but desert plants give up the fruit of their production very reluctantly. Sharp spines, such as a cactus, discourage plant-eaters. The Mule deer avoids these obstacles by eating seeds, although safe to eat, they can be hard to find. Many are small and look like grains of sand. The plant's solar energy flows through the ecosystem as Mule deer, and other herbivores like jackrabbits, fall prey to carnivores like great horned owls, coyotes, bobcats, or snakes (Townsend, Harper & Begon, 2000). Survival in the desert cannot occur...

...involved countries. The United States has been predicted to see either a very small population trend increase, or else a very small population decrease over the next several decades. However, there are many parts of the globe which will have a huge impact on the environment and the planet as a whole due to their widely expected sharp and continuous population trend increases such as Asia and Central America, as well as Africa. These parts of the globe have recently had large increases in their productivity trends and therefore are expected to in turn be hit with large increases in their populations as well. 4. How do principles of system theory apply to the Earth as a living system? Explain interactions between humans and natural ecosystems. From what I learned during the reading of chapters one through four, I am fairly certain that the systems theory is primarily used to understand the many occurrences that are happening at all times in a related extremely detailed system. The system theory puts all these happenings into a category with entirely constantly altering variables. The systems theory can be applied to the helping in understanding our planet as a whole. The system theory helps us to be able to use one happening and relate that to another occurrence we want to learn more about. Basically, the systems theory helps us to use a control group and an experimental group and use the scientific method to find what we are searching for, or at least try......
