Coral Reefs: A Diverse Ecosystem - Coral reefs are one of the oldest and the most diverse ecosystems in the planet; because of such matter, scientists coined coral reefs as ‘rainforests of the sea. The National Oceanic and Atmospheric Administration or NOAA for short (2008) estimated that about 25% of marine life use coral reefs as safe havens from predators, breeding grounds, and feeding grounds despite the fact that coral reefs only cover a small percentage (estimated about 0.1%) of the world’s oceans. It serves an umbrella specie because it serves both as a habitat and a living, breathing organism for other marine animals to thrive....   [tags: coral reefs, ecosystem, marine life] 811 words

The Rainforest: More Than an Ecosystem -   An ecosystem is a community of all organisms in a given area, and the physical environment which they interact with. On the land there are terrestrial ecosystems such as forests, grasslands or rain forests; and in the water there are freshwater and marine ecosystems such as lakes and, say, coral reef. The rain forest is an energetic ecosystem. This means that the rain forest vegetation grows quickly and when dead, decomposes extremely quickly. Rain forest biome is very complex. It includes a myriad of different species of plants and animals that are all adapted to rain, and lots of it....   [tags: organisms, physical environment]

Asian Carp's Harm to the Ecosystem - There is a great big debate over whether the Asian Carp should be considered a menace and about what we should do about them. Grass, Bighead, Black, and Silver Carp are all Asian carp species. According to Keith Lawrence of the Messenger-Inquirer, Carp are being made into fertilizer, and fish oil, as well as being sold to Asia as food products. However, the New York Times say that the Carp could easily put an end to the $7 million dollar fishing industry in the Great Lakes. Aside from economic reasons for keeping or eliminating them, the main reason to stop them from spreading is the fact that they threaten to collapse the entire ecosystem if they get out of control....   [tags: Environmentalism]

Ecosystem Services: Deforestation and Soil Erosion - According to Mooney and Ehrlich (1997), the idea that human beings depend on natural systems traces back as far as Plato. Plato (c. 400 BC) realised that deforestation could lead to soil erosion and the drying of springs (Daily 2007; Gómez-Baggethun et al., 2009). The first modern publication that addresses this concept is in the book Man and Nature written by George Perkins Marsh dated 1864. Marsh started to realize that the world’s resources were not infinite and that natural systems are important to water, soil, climate, the disposal of waste and pest control....   [tags: environmental science, fresh water]

It is especially invasive in the Oceania region, where its disturbance to the natural ecosystem has earned the red fox to be ranked as the 99th most invasive species in the world (Invasive Species Specialist Group 2010)....   [tags: natural ecosystem, problem, control]

Defining Biodiversity Among Organisms - An ecosystem provides a complex framework of biological species which are in phase of degradation in recent times. Since time immemorial, humans relied on plants, animals and microbes for the survival, but now the very pillar of life sustaining systems is at stake. Biodiversity can be defined as the varieties observed among organisms on the face of the Earth. Biodiversity is irreversibly affected by humans.

Economically Evaluating Wetlands - Wetland is a term that can be used to describe wet habitats, such as bogs, fens, marshes etc., that experience either permanent or occasional inundation of water that allows either for hydrophytes to establish or for hydric soil to form (EPA, 2005). Additionally wetlands can be termed as ecotones, as these locations transition between aquatic and dry land ecosystems and in spite of these systems being incredibly diverse from each other they are very much dependent on each other for the establishment of the unique wetland ecosystems (Mitsch & Gosselink, 1993)....   [tags: wet habitats, ecosystem]

Malibu and Yosemite Benefits from Wildfires - Malibu and Yosemite share similar ecosystem, which encourages wildfires and periodic firestorms. In his book Ecology of Fear, Mike Davis argues that Malibu should burn because wildfires are a part of its history. To illustrate his point, he relates numerous historical events from the first settlement of the region to modern days. Despite the high frequency of wildfires in Malibu, humans have continued to settle there in droves. Those settlers have fought the fires, which has done nothing but augment their intensity....   [tags: controlled burn, fire, ecosystem, ecology]

Guam and Rhino Beetle - Nature is a balancing act. When a certain balance of a simple, natural ecosystem is disrupted, it becomes dangerously unstable. This is exactly what happened, and is currently happening, to the island of Guam. This two hundred and nine square mile island has a very simple ecosystem. The only native mammal here is the Mariana fruit bat (Miller). Consequently, when human development started on Guam its animal kingdom started to become quite unstable. For example, the brown tree snake has wiped out half of the bird population and is currently downsizing the population of rats....   [tags: nature, ecosystem, Palau, palm tree]

(Hoefnagles, 2012) In other words, ecology is all living things together in a specific environment, such as the plants and animals of the rainforest, and how they interact. Mankind has had many impacts on the ecosystem – rapid development, depleting natural resources, overhunting, and pollution of various kinds- all of which have resulted badly for other species within our world. There are also natural occurrences which can affect species – acid rain, natural selection, predators, disease, and asteroid/cosmic radiation....   [tags: ecology, ecosystem, environment, extinction]

Bioerosion and Reef Ecology - Bioerosion and Reef Ecology The breakdown of calcareous substrates among coral reefs, or bioerosion, is a facet of reef ecology too often forgotten. The process plays a much more important role than it is usually credited with. Bioeroding species, consisting of many different types of organisms that act on the environment in a seemingly endless variety of ways, interact with the ecosystem and with each other as part of the reef growth and degradation cycle. The degradation portion of this cycle, the part that is most often overlooked, is essential for the development of reefs as the diverse and beautiful habitats that we know them as....   [tags: Bioeroding Ecosystem Ecology Essays]

Value in Nature - Our classical humanist ethic requires that all duty attach itself to an individual “self”, a value-able entity with rights and duties of its own. But nature operates on a different basis: “there are no rights in the wild, and nature is indifferent to the welfare of particular animals” (Rolston, p.75). In order to formulate an autonomous environmental ethics, then, we must be able to move beyond the humanist focus on the self, towards a new source of value and a new type of value. In this essay, I intend to examine the idea of value in nature, drawing especially on Holmes Rolston III’s concept of systemic value and ecosytemic ethics and Aldo Leopold’s land aesthetic (as presented by J....   [tags: Ecosystems] 1994 words
