Corridor Analysis
The United States is centered on the economic development, more specifically on the creation of wealth. It is understandable that creating wealth is of great importance, but continued economic development has lead to degradation of our environment. Therefore, presently we need sustained economic development in conjunction with responsible environmental and resource protection. As development increases, natural linkages within the landscape continue to be fragmented and remnant natural habitats become isolated. As a result, we need strategies to fight the consequences of fragmentation. One such strategy is to create a network of corridors. Corridors are narrow, linear strips of habitat that have wildlife value.
In “New Initiatives for Wildlife Conservation” Larry Harris and Peter Gallagher (1989) state, “Our refusal to incorporate movement across human dominated landscapes into our conservation strategies has made luck the chief prerequisite for survival in highly populated areas.” Corridors provide ecological and environmental quality values. For one thing, they help to maintain biological diversity. Fragmenting landscapes into distinct patches and restricting wildlife increase the risks of movement, and can also have severe consequences for the conservation of biological diversity. Conservation of biological diversity is extremely important because it can reduce the thread of a species becoming endangered or extinct. Corridors help to sustain the biological diversity by preserving migration corridors and connecting fragmented centers of plants and organisms.
Harris and Gallagher conclude that “Habitat connectivity declines with human modification of the landscape and the use of corridors is an attempt to maintain or to restore some of the natural landscape connectivity.” As a result, a network of corridors can improve fragmentation of the landscape and habitats. Corridors can serve as habitats in their own right and they can also serve as linkages for animals that migrate from patch to patch.
There are many different types of landscapes that can function as corridors. A stream corridor is perhaps the best area to create a system of interconnected corridors. The interface of land and water represent some of the richest wildlife habitats.
Although Leopold’s love of great expanses of wilderness is readily apparent, his book does not cry out in defense of particular tracts of land about to go under the axe or plow, but rather deals with the minutiae, the details, of often unnoticed plants and animals, all the little things that, in our ignorance, we have left out of our managed acreages but which must be present to add up to balanced ecosystems and a sense of quality and wholeness in the landscape.
What motivates members of Congress to act the way they do? Mayhew would argue in Congress: The Electoral Connection that members of Congress are ‘’single-minded re-election seekers’’ and that re-election is their one and only goal. Whilst the assumption that all members of Congress are ‘‘single-minded re-election seekers’’ does go some distance in analysing the motives behind members of Congress, the reading fails to take into account the other key goals of members of Congress. Other goals include good policy and future career positions. It is important to remember that the achievement of both re-election and other goals are not exclusive, members of Congress often are motivated by more than one goal.
Ever since 1973, when the Endangered Species Act came into being, conservationists and private landowners have been debating over whether to preserve the habitats of many endangered species found in unprotected areas (Ligon et al, 1986). Increasing levels of human development has led to the cutting of old-growth forests and construction of roads and other physical barriers to wildlife. These activities have greatly contributed to the fragmentation of wildlife habitat, which has had detrimental effects on the population structure and survivorship of the affected area’s indigenous species. One species that has been affected by habitat fragmentation is the red-cockaded woodpecker (Picoides borealis), a nonmigratory bird with a home range covering most of the southeastern United States (Roise et al, 1990). Habitat fragmentation has led to the loss of genetic variability, nesting sites, and suitable population sizes to support cooperative breeding requirements. These factors have been responsible for the precipitous decline of the red-cockaded woodpecker. Because the red-cockaded woodpecker provides important ecological and economic benefits to both humans and the environment, we should strongly consider enacting a conservation plan for this species.
The western style 2013 Australian feature film Mystery Road centres around indigenous detective Jay Swan as he investigates the murder of indigenous teenager Julie Mason. Swan’s continued struggles to convince the rest of the local police – who all happen to be white males – to help him to solve the case lead him to find a drug ring. Sen represents the idea that indigenous people do not receive justice through the construction of Jay Swan and the unjust way the rest of the Indigenous community are treated by the white community and predominately white police force, encouraging my empathetic response. Sen also explores the police as corrupt and apathetic. In recent years, all over the world, but particularly in Australia in the 1980’s onwards,

The effects of deforestation around my home and throughout my state are becoming more evident every day. When a deer or other wild game loses its home, they move into cities, urban areas, and parks; thus causing issues with the human population. Most people living in Illinois have hit or nearly killed a deer driving on Southern Illinois roadways. This common occurrence could be kept at bay or maybe even avoided if the deer and wild game had more space to reside. There are many points that coincide with this reality but the main issues are the small subtle ones that affect everyday life and are often overlooked. Picture the Illinois we will leave for our children. Do you see a lush green forest or miles and miles of concrete and steel?
Within the moraine there are countless species of animals that will soon be displaces from their habitant. Many of the creatures are endangered or rare, for example the West Virginia White Butterfly, Jefferson Salamander, Red-shouldered Hawk, American Ginseng, and the Hooded warbler. Putting these animals in zoos, or special buildings is not the answer, because they will not have the surroundings that they are used to in the wild. Also, by building roads in the Moraine, there will be a bigger chance that these animals are run over, or hit by the incoming cars. In conclusion, we should preserve the Oak Ridges Moraine and its animals because they are endangered they can?t live in zoos, and may be killed by the urban environment.
...rupt native species and ecosystem hence making the restoration of both evolutional and ecological potential almost impossible. Whereas Donlan (2005) concluded that re-wilding North American is the best conservation strategy to the African and Asian threatened megafauna, meanwhile re-wilding will restores the evolutionary and ecological potentials in the process. In my point of view, Pleistocene re-wilding must not be implemented simply because the introduced species might fail to adapt to the new environment. High costs and disease outbreak are another challenge that can’t be ignored.
Shirley Jackson wrote “The Lottery” in 1948, not long after the second World War. The horror of the Holocaust was still fresh in everyone’s mind’s. Jackson wrote this story to remind everyone that we are not so far from this world of sadistic human sacrifice. She created a town, very much like any American town, with the gathering of the towns people to celebrate some annual event. She wanted to shine a mirror on contemporary society, a reflection of humanity, or rather, inhumanity. One would think that she was protesting against the shallow hypocrites that rule the world.
A keystone species is a species that’s whose impact on its community or ecosystem is larger and greater than would be expected from its relative abundance or total biomass in the environment. The presence of keystone species maintains higher species diversity in ecosystems than if keystone species were absent. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone inane arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass or productivity. It became a popular concept in conservation biology. Although the concept is valued as a descriptor for particularly strong inter-species interactions, and it has allowed easier communication between ecologists and conservation policy-makers, it has been criticized for oversimplifying complex ecological systems.
Due to human activity, the natural fauna of the world is becoming displaced; this is especially profound in terrestrial mammalian species. This study specifically looks at fragmented land affecting the northern brown bandicoot, Isoodon macrourus, in the city of Brisbane, Australia. The experiment was conducted using mark-recapture methods and radio tracking in order to distinguish bandicoot home ranges, densities, and habitat. It was observed that the bandicoots sheltered during the day in areas with tall, dense grasses and weeds and exhibited nocturnal foraging in urban lawns and recreational areas within small ranges. The study suggests that the grass and weeds provide an ideal habitat for the bandicoots, allowing them to thrive in large populations.
“The Lottery” is a story written by Shirley Jackson. By looking at the title you may think about money prize. In this story takes the readers expectation to another level. By the two words of the title there is no way the reader did not get hook to reading this story. In “The Lottery” Shirley Jackson, uses symbolism, irony, and imagery.
In this new age of technology and advances in every possible field of study, many people forget about the environment. Some will just throw their trash all over the place with no concern for the possible consequences. Of course, there are many consequences, but only one comes to my mind. That is the demolition of species’ homes or habitat destruction. Habitat destruction or habitat loss is the altering or elimination of the conditions that plants and animals need to survive. “The primary threat to the world’s biodiversity is habitat destruction” (Okey p.1). Prairies have been greatly affected. The “loss of prairie habitat ranges from 20 to >99 percent depending on the region” (Benedict, Freeman, & Genoways, p.161). Habitat destruction can be caused by many things. These include:
This method is effective because tiger corridors are successful in increasing the connectivity between national parks, but evidence also suggests that they are important for breeding with evidence of tiger cub tracks within the corridor. Another importance is the use of the corridor as home territories with evidence collected from the Tiger Conservation and Protection Unit for the Fauna and Flora International Sumatran Tiger Project [7] shows the importance of reducing the fragmentation of tiger habitat using tiger corridors. I would suggest this data is valid and reliable because the programme is lead by Joe Smith PhD who has a Master’s Degree in Wild Animal Biology from the Vetinary College and Institute of Zoology in London. His experience and education ensures that this project would be carried out correctly and the results would be both valid and reliable
Loss of biodiversity is an environmental issue that is causing a lot of global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth. There are measures that are being taken worldwide to prevent loss of biodiversity. Many wildlife sanctuaries have been built worldwide to preserve the lives of various endangered species. However, it is important to remember that every individual has a role in the protection of wildlife and biodiversity. Every human being should play his part of the role by following simple rules such as stopping others from the hunting of endangered species, preventing deforestation, encouraging reforestation and creating awareness among fellow human beings.
