Ecosystem Theses Samples For Students

Introduction

Climate change is a major environmental problem, causing concern to various corners of our ecosystem. It is a result of global warming, environmental pollution and inefficient use of our natural resources. Climate change has affected almost all living organisms, including plants, animals, microorganisms and undoubtedly, man. It poses a serious threat to our ecosystem and is listed as a major concern in the Grand Challenges of the U.N. for Millennium Development and Millennium Ecosystem Assessment (Garrett 490). A wide variety of its implications, have made climate change, an important topic for researchers. There has been more awareness among researchers ...

It is claimed by the scholars that the ocean temperatures are affected by the climate change. In addition, there is a set of other effects of the climate change for the marine organisms - such as changes in the ocean chemistry, supply of nutrients, systems of wind and food chains. These factors make their impact on the abundance, distribution, breeding cycles as well as migrations of marine animals and plants. With the increase of the temperature, the animal and plants, which inhabit the ocean and seas, shift towards the poles. In such manner, the marine food webs are changed ...

Analysis of Temporal Trends in Persistent Organic Pollutants in

Analysis of Temporal Trends in Persistent Organic Pollutants in Air, Water, Food Chain and Humans in United States
Introduction
Persistent Organic Pollutants (POPs) are synthetic organic chemicals, which are persistent in environment. Its long-range transport leads to global pollution. These materials are lipophilic and they are accumulated in the food chain as they are found in fish and marine mammals (Arnot & Gobas, 2006). These toxic materials are spread in environment through different human activities. They pose adverse effects on air, water, food chain and humans. In United States, over the last two decades there has been a continuous ...

"Feral pigs are one of the most destructive animals in the state; they continue to be a serious threat to our native bird habitats and our native rainforest. Feral pigs are a major factor in rainforest degradation."These are the words of George Masesengale a member of the Audubon Society in Hawaii, on the impact of feral pigs on rangelands, which was published on 25th March 2008 on the honoluluadvertiser.com (http://the.honoluluadvertiser.com/article/2008/Mar/25/ln/hawaii803250318.html).
According to this post, law makers and environmentalists were calling on the Hawaii state government to explore tactics that would aid in the control of the feral pig population in ...

Introduction

In modern times, human activities caused and continue to cause massive changes to the composition of the environment. One of the most pressing concerns of both scientific and public communities is the advanced greenhouse effect brought about by the anthropogenic activities worldwide. The Intergovernmental Panel on Climate Change (IPCC) has reported that climate change already showed strong impacts on human societies and the natural world. This impact is expected to continue for the coming years. (IPCC, 2007)
Adaptation is a necessary strategy. This is because the present and the forecasted disruption sin the climate as advanced by the continuous and ...
