Adverse Impacts of Landscape Fragmentation on Biodiversity
Landscape fragmentation can impose devastating and irreversible consequences on the biodiversity of ecosystems. Because of the conflicting interests between ecology and human economic benefit, it has become increasingly important to find solutions for a harmonic balance. It is imperative for people to recognize the impacts of biodiversity loss and increased extinction of many species. These impacts must be understood in order to protect landscapes and the immense biodiversity they contain. Raising environmental consciousness through education and public cooperative efforts, as well as promoting resource conservation and changing consumptive patterns, are just a few ways that we can begin to protect biodiversity.
What is landscape fragmentation?
Landscape fragmentation can be characterized as a break up of a continuous landscape into more smaller, less-connected patches by roads, clearing for agriculture, commercial and residential development, and timber harvesting. Clear-cutting can break up mature, contiguous forest until the clear-cut area has regenerated to a point that it does not act as an ecological barrier to interior species or species that rely on continuous, mature forests. Much of the work that has sought to measure landscape pattern and habitat fragmentation comes out of the disciplines of conservation biology and landscape ecology (Theobald 1998). These disciplines are founded on the premise that landscape patterns strongly influence and are influenced by ecological processes (Forman and Godron 1986).
How does landscape fragmentation affect species diversity?
Landscape fragmentation contributes to loss of migratory corridors, loss of connectivity and natural communities, which all lead to a loss of biodiversity for a region. Conservation of biodiversity must include all levels of diversity: genetic, species, community, and landscape (CNHP 1995). Each complex level is dependent upon and linked to the other levels. In addition, humans are linked to all levels of this hierarchy. A healthy natural and human environment go hand in hand (CNHP 1995). An important step in conservation planning, in order to guarantee both a healthy natural environment as well as a healthy human environment, is recognizing the most endangered elements.
Biodiversity is influenced by landscape fragmentation at various scales of space and time. The extinction of ecosystem types and component species may cause an increased patchiness of the landscape, resulting in lower population sizes and decreased connectivity. As a result, inhabitants may experience decreased dispersal abilities and lowered gene flows between populations.
...e slowly destroyed, effects would not only be seen at a local level but be noticeable on a global level. Mitigation areas should be established to alleviate any damage already done, and to prevent any further harm. These areas can help support fragile plant and animal life. Biodiversity is essential to our lives and the stewardship worldview should be used in this issue.
Destroying the habitat of different plants and animals, they no longer have a place to live. Their food source and nutrients are taken away and have nowhere else to go. These organisms will die out and there will be a loss in the diversity of that ecosystem. That ecosystem can then start to crumble as the habitats are taken away and the plants and animals have no home. With no habitat in which the organisms can live in, there is going to be very little diversity.
Biodiversity is the variety of species in the world or in a particular area or habitat and their loss is prevalent all over the world. This has mainly taken place because of habitat loss that is caused by deforestation, overpopulation, pollution and global warming. It is important that we (humans) take part in an action to stop the habitat loss we are causing. Biodiversity, from sea to land, all play an important role in our ecosystem and without them, we would suffer.
Even the United States struggles with issues of racial discrimination despite being a society highly based on immigrants and multicultural diversity. On one hand, people frown on treatment based on race, whether that is on an individual or group level. On the other, people are tired and annoyed by the seemingly constant call of discrimination. All of these feelings culminate into the debate pertaining to the use of racial profiling. Likewise, there are some individuals that hold a certain level of acceptance in regard to racial profiling. However, what is lost in the process because of that acceptance? There are many components that need to be thought about in reference to the use of racial profiling. In addition, it can be viewed from varying perspectives, such as through the use of statistics, by looking at social norms and taking into account moral/ethical values. Although racial profiling has been denounced, its use has continued to come up repeatedly. Furthermore, it is very apparent that certain circumstances cause the use concept of racial profiling to resurface.
This paper will define the topic of racial profiling as well as the history, present day issues, how it may be dealt with in the future, and my opinion on the topic. Racial Profiling is the practice of targeting people of color or a certain ethnicity for investigation or arrest. History starts with the New Jersey State Police department of investigation of activities instituted the term racial profiling that we know today in order to raise awareness of the issue. Some of the current issues today with racial profiling have caused many problems for the criminal justice system entirely, hindering police efforts in communities and losing the reliability of the people. The future of racial profiling has been a debatable topic but though it may be impossible to get rid of entirely much progress has been made in controlling it. My opinion on the topic is that maybe more training in how to use discretion when making a gut feeling about a situation.
The Western forests are drastically different from what they were like before the European settlement. In pre-European time, the forests were open and park-like with only 25-35 trees per acre surrounded by areas of open grasslands. One could easily ride a horse through the spacious forest. This, however, is not possible in today's forests. Today, for example the Ponderosa pine forests, have over 500 trees per acre, creating thick dense areas of trees, brush, and bushes (President Bush, 4). The pre-European forests were subject to frequent low inte...
Natural habitats used by man or tampered with tend to become unsatisfactory or unsuitable for the native wild species. As I learned in class, habitat loss is the number one threat to modern primates. Not only do primates suffer, but habitat loss is the greatest threat to various parts of life on this planet that humans have caused. Simply speaking, along with habitat destruction, ties in the extinction of diverse species. “Biodiversity as a whole forms a shield protecting each of the species that together compose it, ourselves included. What will happen if, addition to the species already extinguished by human activity, say, 10 percent of those remaining are taken away? Or 50 percent? Or 90 percent? As more and more species vanish or drop to
According to Angela Lee “ The key to success is Grit “ . Studies show that students with Grit are more successful than the students with a high I.Q. , In fact Grity kids were most likely to graduate than their peers . The difference between kids with Grit and the others is that , Grit kids aren't willing to failure put them down , in other words they are willing to fail to start all over again . Grit kids know that failure is a part of learning and
To begin, what society is often blindsided by is that racial profiling is real, and is used in unfair manners by police officials. According to the article, “Jim Crow Policing” published on The New York Times,
Throughout American history, there has been, without a doubt, an indisputable sense of racial tension among the various ethnic groups of the nation. These issues have been traced back since the establishment of the colonies and are still prevalent today in one form or another. Although the tension is no longer as intense as it was before, it continues to exist today in modern society in the form of racial profiling. Racial profiling can be defined as the use of race or ethnicity as criteria for suspecting someone of having committed an offense. In recent decades, a trend has been observed in which police forces have been distinctively targeting black and Hispanic Americans more often than other ethnic groups. Police departments have argued
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:
Biodiversity loss can lead to extinction, and hurt human life. It is our responsibility to take care of the environment. We bring in machines that harm the environment and destroy animal life. We need to limit ourselves on how much land and resources we consume. There are major issues that are causing species to become extinct and hurt our way of life and other animals do to the change in food chain.
Worldwide, Canada is recognized for its high living standards. There is clean, fresh water, an abundance of food and resources, and a relatively stable job market. Canada possesses political stability, democracy and numerous social programs. Human rights are highly valued and all Canadian citizens are protected under the Constitution by The Canadian Charter of Rights and Freedoms. Each citizen is guaranteed a variety of rights such as the right to vote, the right to free speech and the right to practice one’s culture without fear of persecution. In many countries, particularly in developing areas, citizens are not protected by the law and often live in fear and poverty. Canada’s reputation as a free and democratic society lends an appealing image to citizens who face injustice on a daily basis.
Many species are widely distributed and thus, initially, habitat destruction may only reduce local population numbers. Species which are local, endemic, or which have specialized habitats are much more vulnerable to extinction, since once their particular habitat is degraded or converted for human activity, they will disappear. It further states that the species extinctions may be a major contributor to global change. In other words, means that the loss of biodiversity seems to be much greater than we initially understood, and the expansion and destruction of natural habitats will result in major detrimental effects on our environment as we destroy the web of life.
Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.
