  1. Essay On Endangered Plants Biodiversity Imagine this: you step outside and feel the barren, rough, red Earth beneath your feet. There's not a single plant in sight–no rustling of the leaves, no mighty towering trees to block the severe winds, and the scorching heat of the sun searing upon your face because there's no shade. And when you take a whiff of air, you feel nothing filling up the space inside your lungs, liberating your body's activities. What's wrong with this picture? It's not possible, of course. Even though plants aren't the building blocks of life, they're pretty close and without them, most of life wouldn't exist–YOU wouldn't exist. In my research, I will go in–depth about biodiversity–which defines as a quantity of the relative diversity among...show more content... Based upon the same experiments and samples taken, it was concluded that the atmospheric nitrogen pollution was caused by the burning of fossil fuels and rigorous agriculture (Ananthaswamy, 2004). According to the 2004 release of the Threatened and Endangered Species System (TESS) information, there are 599 endangered plants and 147 threatened plants in the US alone (TESS, 2004). These listings rely on a very stern legal system. Whether they can be labeled "rare", "threatened," or "endangered", it is determined by the measure of endangerment the species sustain. An "endangered" type is one that is in jeopardy of extinction throughout all or a major fraction of its range. A "threatened" species is one that is likely to become in danger of extinction in the future (UFWS, 2004). Ways for prevention of plant dissolution/ rewards Here in DeKalb County, we have several different threatened plant species. They are: Bay–star Vine, Flatrock Onion, Granite Rock Stonecrop, Indian Olive, Piedmont Barren Strawberry, and the Pool Sprite Snorkelwort. We have one endangered plant: it is the Black–spored Quillwort (UFWS, 2004). There are over 542 discrete approved ecosystem recovery plans. Some plans cover more than one species while a few have different plans covering various parts of their ranges (TESS, 2004). One organization is the Botanic Gardens Conservation International. It has just recently been added as a participant of the bigger ...Get more content on HelpWriting.Net...

  2. Essay on Biodiversity Biodiversity INTRODUCTION Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be...show more content... Simultaneously, thousands of other species across the globe face the same threat: extinction. Biodiversity is an essential part of our world, our global ecosystem. As Planet Earth?s resources diminish and its creatures vanish, those who recognize the need to preserve what is disappearing look to international politics to accomplish what individuals cannot. The most important instrument for implementation of international policy has been the Convention On International Trade in Endangered Species of Wild Fauna and Flora (CITES), which went into effect in 1975. The plight of the rhinoceros is not unlike the all–too–familiar danger that the elephant faces. Illegal trade is greatly responsible for the endangerment of the species. Valued for their ivory horns, over 90% of the five rhino species have disappeared, while the rest continue to dwindle. The worth of one rhinoceros horn is $44,000, and the demand remains high in the countries of China, Taiwan, South Korea and in the Middle East. In East Asia, the horns are regarded as powerful medicinal tools, known to cure everything from nosebleeds to food poisoning. In a powdered from, the horn is thought to be a powerful aphrodisiac. Similarly, the animals? genitalia are also considered extremely valuable. Existing rhino populations continue to decline. In East Africa, the Black Rhinoceros ...Get more content on HelpWriting.Net...

  3. Biodiversity Biodiversity a.Biodiversity– is the degree of variation of life. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be highest near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth. It is the richest in the tropics. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in the mid–latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends...show more content... As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but usually encompass specific, limited spaces. f. species diversity– is the number of different species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant). Species diversity consists of two components: species richness and species evenness. Species richness is a simple count of species, whereas species evenness quantifies how equal the abundances of the species are. g. species richness–is the number of different species represented in an ecological community, landscape or region. Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions. 2. Differentiate the following Genetic diversity | Community diversity | Landscape diversity | level of biodiversity, refers to the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. | An ecosystem is a higher level of community. A community is made up of ...Get more content on HelpWriting.Net...

  4. Biodiversity And Biodiversity The current climate change is projected to have a significant influence over biodiversity. The changes create risk to almost all the species on land to extinct by 2050. Due to earth's rapid warming that is now faster than at any time in the past 10,000 years, the species survival is likely to be at the fullest risk. The rapid heating temperature on earth almost always caused danger to plants, animals, places and even people's livelihoods. It also damages the ecosystem, including coral reefs, whole loss of unique forms of life that will create a complete disaster on earth. These changes force the species to adapt to new climate patterns, if species can not evolve to live in a certain ranges of temperature, or when it actually lives dependent to a certain temperature range, then its existence is endangered. With the more intense rising of sea level and warmer ocean, the prolonged period of a shortage of water resulted threaten crops, wildlife and storage of fresh water. Various studies reveal that species usually move to higher elevations and latitudes in response to climate change. The local extinction also record the loss of population at the warm edge of species ranges that located in the lower elevations and latitudes. The data particularly show that roughly half of the 976 species surveyed has extinct. Loss of species is normally happen in tropical region across the climatic zones, habitats and group of organism. The species mostly are Earth's species animals that ...Get more content on HelpWriting.Net...

  5. biodiversity Essay "BIODIVERSITY" Biodiversity, as defined by E.O. Wilson, "is meant to be all inclusive– it's the genetic based variation of living organisms at all levels, from the variety of genes in populations of single species, through species, on up to the array of natural ecosystems." This includes plants, animals, insects, fungi, bacteria, and all microorganisms. All of these things create what is known as a web. These things interact with each other in some way there for they depend on one another throughout their lifetime. There are many separate ways in which we can study biodiversity. These ways include, genetic, species, community, ecosystem, and taxonomic diversity. Biodiversity can be best...show more content... In the video, during the drought, the side of the field with a more diverse environment held stern as the other wilted away. Areas that are very diverse are very important to humans as well. They provide a wide arrange of pharmaceuticals such as aspirin and penicillin. "Some 40 percent of U.S. prescriptions are for pharmaceuticals derived from wild plants, animals and microorganisms.(E.O. Wilson)" They also provide fruit, oils, beverages, drugs (including illegal narcotics), fuel, and much more. Humans also benefit from biodiversity from what E.O. Wilson calls "biophillia," which is the natural affiliation humans have for natural environments.(E.O. Wilson) Old growth forests play a dentrimental role in biodiversity preservation. It's most important feature is biodiversity. Old growth forests provide us with many of the things that we as humans take for granted, for example, breathable air pure water, and pest control through birds, bats, and insects. In the Eastern U.S., most of the old growth occurs in small isolated areas. Scientist have come to the conclusion that even if these matured areas cover a substantial portion of landscape, it will not provide long term diversity for many species that live in such a community. (How much old growth..?) Many environmentalists are increasingly concerned with this biodiversity ...Get more content on HelpWriting.Net...
