To summarize what this article talked about it was a study done on the effects of soil degradation and the effects on the vegetation in areas around watering points and normal grazing lands. The study showed that in these ecosystems the overgrazing reduced the ecosystem diversity of plants in poor soils. It also talked about how overgrazing around certain areas can not only destroy the soil but it can also cause the destruction of certain types of species. Overgrazing differs in all areas of the world but it still has a common problem which is that when there is overgrazing no matter what type of environment you are in that environment will be
Provide one action we as humans engage in that leads to the extinction of each of these components. Action affecting Lichens = Lichens depend on air and water for nutrients which is affected by things such as air travel and exhaust fumes. Action affecting Trees = People cutting down trees for useable items is one main way that leads to extinction. Action affecting Flowers = People are clearing off land in order to plant crops and trees Action affecting Bees = There is intensive farming being done all around the world to keep up with the supply and demand of food. As a result this eliminate food that bees pollinate from.
Tourism has caused habitat loss for those endemic animals of the environment, specifically the pygmy possum. The pygmy possum is endemic to this environment, coz of its extreme weather for breeding and hibernation. The construction of homes and resorts at Mount Kosciuszko has resulted in the loss of habitat for the pygmy possums. The loss of habitat has resulted in man-made homes for these animals. The location of this home for the pygmy possum was made difficult for breeding of these animals.
Record your observations about the size of the grease stains in your lab notebook in a data table.Count how many squares are covered in grease. You should also count squares that are only partially stained. Remember to record all of your data in your lab notebook. It is important to repeat experiments so you gather plenty of information. 7.Repeat steps 1-6 for the other three varieties of potato chips.
Due to animals consuming more grass than can be produce, the ground becomes scattered leaving the soil exposed to erosion. The NRCS (Natural Resources Conservation Services) has a program to help prevent overgrazing. The program “provides information and support to enable ranchers who own their lands to burn unwanted woody plants, reseed the land with perennial grass varieties that hold water, and manage cattle so that herds are moved to a new location before overgrazing occurs” (Wright & Boorse, 2011, p. 288). If this problem is left untreated, could be a threat to the food chain. Deforestation is when trees and other vegetation is being removed converting the forest to another land use, this exposed the soil and often leads to erosion and loss of soil fertility.
In this process acidic water flows over and through the ground and affects varieties of plants and animals. The water has become too acidic, and this creates a problem to the environment because all living things depend on water. Dry deposition is also a form of acid deposition, but refers to acidic gases and particles. “Half the acidity in the atmosphere falls back to earth through dry deposition”. The wind blows these acidic gases into building, cars, homes and trees.
This is significant, because if one species of animals departs, it causes the food cycle to be rearranged endangering the lives of multiple living organisms. They provide one of Canada’s largest negative impacts on the environment, releasing poisonous carbon dioxide emissions which are getting out of control. If these greenhouse gas emissions are not reduced it can result in the melting of polar ice caps in the Arctic. These oil sands are not only poising the air which we inhale, but also numerous waterways, food supplies, and if this process continues, possibly endangering the extinction of species. Green House Gas emissions are relatively caused by exponential increases in carbon molecules within the Earth’s atmosphere.
Janella Benitez Math 216 Honors November 28, 2011 Writing Assignment 3 In the article, “The Invasive Shrub European Buckthorn (Rhamus cathartica, L) Alters Soil Properties in Midwestern U.S. Woodlands” demonstrates how invasive shrubs and plants can alter soil properties the can have important conservation in systems. These shrubs can alter the chemical properties in soil such as, nitrogen and carbon. With these alterations, it can impact the chemical properties of the soil as well as effecting other ecosystems around. In the “Introduction” section of the article shows how invasive species can be capable of changing the infrastructure and ecosystem processes of habitats. The species can also be the cause of biodiversity loss of the ecosystems.
It has been recorded at a number of sites within the park. The fungus has the potential to impact of the vegetation, especially along the heathy ridge tops where grass trees are dying. It also affects a lot of the native vegetation and causes the death of a lot of other species. The disease spreads naturally but also through infected soil when transportation travel over it. Quarantine and vehicle hygiene to limit the spread can only be achieved my
