A Threat To Wildlife And Bio-Diversity


Thesis Statement: The acceleration and diversification of human induced disturbances upon natural ecosystems during the past decades has contributed to wildlife habitat fragmentation. The changes in land use have driven wildlife managers to reconsider the benefits previously attributed to the Edge Effects on wildlife diversity.

Habitat fragmentation has been recognized as a major threat to the survival of natural populations and to the functioning of ecosystems. The reduction of large continuous habitats to small and isolated remnants affects the abundance and species composition of various Taxa. Some possible factors contributing to this decline include changes in food and cover availability, microclimatic effect, evolution of predation, loss of genetic variation, and lack of recolonization following local extinctions. Ultimately, habitat loss and fragmentation are processes that isolate small populations, which have higher extinction rates that may lead to a reduction in biological diversity. The acceleration of the land acreage consumption by human activities to the detriment of natural areas has revealed dramatic changes in the land uses during the past decades. Previously thought to be beneficial to wildlife habitat and diversity, the edge effects have been reevaluated by wildlife managers.

I. Definition:

A. Wildlife habitat

In a formal sense, wildlife habitat can be defined as an area with the combination of resources such as food, cover, water, substrate, topography, temperature, precipitation, and security that promotes occupancy by individuals of a given species and allows them to survive and reproduce (Morrison et al., 1992). Usually, the quality and extent of an an...

Wildlife and Conservation Efforts in Africa Essay - The dynamic natural environment and abundant wildlife are the most prominent features of the African continent. Due to its wide variety of biomes ranging from tropical forests to arid deserts, Africa consists of bountiful wildlife diversity. However, because of environmentally harmful human interactions, the variety of biomes is shrinking to all-time lows, which causes wildlife to die out. These detrimental human interactions, particularly livestock overgrazing and desertification, occur partly because the native people who depend on the land for daily life do not realize the potential benefits of wildlife and the unsustainability of their current ways....   [tags: Wildlife Conservation]

Why do we have to risk the lives of these innocent animals. I chose this topic on wildlife preservation because I feel that we humans who have voices need to speak up and do so.

Supporting Diversity Essay - Supporting Diversity “Without awareness and knowledge of gender, race, culture, and ethnicity, therapists and other helping professionals could unwittingly engage in cultural oppression (A.

After surviving the destruction of the Third Reich, the civil rights’ movement of the 1960s and the women’s movement of the 1970s, it is hard to understand why the need for diversity still has to be discussed except that as a society, we are infants when dealing with diversity issues....   [tags: Diversity]

Essay on The Cost of Human Cloning: A Threat to Individuality and Diversity - The Cost of Human Cloning: A Threat to Individuality and Diversity Have we as a society come too far too fast. This is a very applicable question recently asked by senator Roger Bennett, from Michigan, before the Senate on the topic of human cloning. It is speculated that we as a human race have the technology to make a clone of any given human (Jackson 2). If this is done, at what cost is it done. If cloning is allowed it will come at the cost of misguided effort, the creation of a process known as gene selection, and loss of individuality and diversity....   [tags: Cloning]
