Lake Tahoe Biodiversity
Lake Tahoe is hailed as one of the most beautiful lakes in the United States. Over the last century or two, the fish biodiversity of the area has been a sight to behold. However, biodiversity tends to change over time. This particular report focuses on fish and there is much to be said even about fish in particular. This report will consult multiple sources and will create a rough timeline of what has been happening with the fish biodiversity of Lake Tahoe over the last one hundred and sixteen years. While some fish biodiversity changes are caused by entirely natural factors, human presence and activity has surely played a role as well.
One rather odd and vexing thing that has happened with the Lake Tahoe fish population over the years has been the introduction of non-native species to the ecosystem that is the lake. Indeed, there have been some developments over the last five years or so that involve a breed of bass that is not native to the area. A problem with this development is that the bass species in question is extremely invasive and aggressive. The bass in question is the smallmouth bass and they are extremely adaptable because they can survive in a litany of different climates and situations. They are much abler to adapt and survive to different environments than other species of bass. The solution used thus far to address the issue has been to remove the invading bass from the area. As of 2011, a total of five thousand bass have been expunged. The effort has been the part of a larger effort by the California Department of Fish and Game. They created the Lake Tahoe Aquatic Invasive Species Program (Associated Press, 2011).
A major method that has been used to counteract the invasive and harmful species, not to mention pollution and other manmade problems, is to reintroduce species that are native to the area and in a way that allows the fish to be self-sustaining in terms of its population. Precisely that was done when 90 Lahontan cutthroat trout weighing up to two dozen pounds were allowed to spawn and...
Biodiversity in Lake Baikal We are in a world where there is a continuous exploitation of natural resources and very little care about the environmental consequences. Rapid industrialization has created havoc to the delicately balanced ecosystems. The effect that human population has had on global ecosystem is certainly undeniable and global biodiversity is being seriously challenged. The rapid deforestation of Amazon forest, the irreparable damage that we have done to the
negative effects of degradation of the environment. It will first discuss human population as a cause for environmental degradation by also relating to afferent effects. It will then bring into equation urbanization and industrialization which are closely linked. Ultimately, the general effects of global warming, as both a cause and an effect in itself, will be considered. Key terms: environment, population density, urbanization, industrialization, global warming. Man has impacted the environment
Economist on impacts of growth, "The Effects of Growth: The Long View" discusses, in brief, how economic development of human societies is actually beneficial to biodiversity, in spite of some negative aspects linked to it. It starts with a comparison of two nations -- South and North Korea -- and the way their economics and politics contribute to local biodiversity, that is, the region's forest cover. An identical comparison
But the supply far outstrips demand, Europeans are finding. The climate of this marketplace itself is decidedly cloudy. Advance prices have plunged by half. At this point, one shouldn't portray it as a liquid, vibrant market," said Atle C. Christiansen of PointCarbon, a Norway-based research firm (Climate, 2004). More than six years after governments negotiated the historic climate accord in Kyoto, Japan, the world is taking only halting steps _ not always
Yet, there have been transplant successes in sheltered embayments. One of the major conclusions that have been seen is that the cost of reef repair and coral transplantation is generally high but effectiveness is usually very low. Protection and conservation, rather than restoration of damaged reefs, is the preferred priority. However, there have been a number of successful mitigation efforts in Hawaii (Jokiel, ). Disorder is a natural structuring force
Social Ecology of Health Promotion Module 05 Question 01: explain the rationale behind the federal government's approach to regulatory containments in food. The federal government's approach in relation to the regulation of the containments in food, aims at protecting the consumers on food insecurity through elimination of food pathogens. It is the role of the government to enhance the health system and conditions of its citizens through adoption and implementation of various
