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.
(You may do more than one opposing view) One viewpoint that differs from mine is reduced effectiveness of pesticides. Just as some populations of mosquitoes developed resistance to the now banned pesticide, many people are concerned that insects will become resistant to other crops that have been genetically-modified to produce their own pesticides. 7. If your viewpoint was followed, what would be the implications and consequences (good and bad) for appropriate stakeholders and all of
Summary: Environmentalists and biologists are struggling to decide what needs to be done for the spotted owls, which were listed as a threatened species back in 1990. Another owl, the barred owl, has posed a recent threat on these threatened spotted owls. Both the barred owls and the spotted owls are native species to the Pacific Northwest, however, because the barred owl seems better suited for the environment, they are posing an even greater threat for the already threatened spotted owls. Do to loss of habitat from foresting, the spotted owl began to greatly suffer. The barred owl on the other hand, is good at everything.
The effects of pesticides can be devastating. They build up and cause problems for the future. Improper use of pesticides can affect all the organisms that live in that ecosystem. The use of pesticides needs to be cautiously monitored, in order to protect the environment and species from the harmful effects that pesticides can cause. Pesticides can travel great distances through the environment even if that is not the intention.
From the beginning geography held a profound effect on the evolution of Mesotopamian civilization, as Mesotopamia was settled in a catastrophic area. Being positioned between two river valleys, the Tigris and Euphrates and surrounded by little environmental protection left much of Mesotopamia open to constant cultural invasions and attacks. In time Mesotopamia became home to a huge collection of many cultures. Although the older cultures customarily looked upon the newcomers as inferior, the new just as invariably contributed valuable innovations to the old. Despite separate cultures however, each civilization managed to reside, maintain, and contribute new ideas and developments along the way.
Populations are under increasing threats from humans by fragmentation of habitat, agricultural practices, chemical use such as pesticides and herbicides, invasive non-native plants, and disease caused mainly by the use of commercial bees for honey and other products (Kearns et. al 1998). To ensure that the relationship between the pollinator and the flower remain intact, conservation efforts must be effectively executed to ensure that both bees and the flowers they use are protected. History of Bees: Many hymenoptera species exist in the world. These include wasps, ants, and bees- all of which show a unique social structure and communication abilities.
Amy LaCasse Environmental Studies Charles Kaminski 18 July 2011 Environmental Science- An Interdisciplinary Approach Environmental science is a broad and complex field concerned with the study of the natural environment and the effects on that environment of human activity and natural events. This branch of science deals with such issues as deforestation, soil erosion, air and water pollution, global warming, loss of fisheries, the fate of hazardous chemicals in the environment, management of the earth’s water resources, and the destruction of habitats on land and in the ocean. All of these environmental challenges are multidisciplinary in nature. Because these concerns are so far-reaching and many environmental problems are interconnected, environmental science encompasses a number of varied areas of science. In order to understand each environmental challenge well enough to develop viable solutions, scientists must have expertise in several disciplines of science.
Moreover important requirements such as medicine, ‘as well as sources of energy, fibres and structural materials, come from a few exploited species ’ [3] that have been discovered. Furthermore our solution in tackling poverty, hunger, and diseases may come from species that are not yet discovered. Additionally species have many other vital functions that also benefit humans, for example some species such as Lichens are indicator species meaning that they help monitor harmful pollution
For example, soil can be affected by heavy rains or floods. Many abiotic factors can affect the lifestyle of an organism. These abiotic factors have subfactors, such as climatic and edaphic factors, that can have a huge impact on the survival, distribution, abundance and over-all ecology of the biotic units of the ecosystem. All these factors affect different organisms to different extents but without these environmental factors, organisms cannot exist. This study allows us to determine the variations of abiotic factors affecting organisms.
There are also good impacts especially to the moving species as they have enhanced survival rates, and also lack native predators. As a result of alien species, it can be difficult to control. They are easily established and spread fast so can become out of control. The threats of invasive alien species in forest systems can be best understood at local and global levels. At the local level, the introduction of specific pathogens or pests from one continent to another has led to dramatic reductions or losses of species in forest ecosystems.
