vegetation over time within ecosystems in the British Isles‚ such as human activity‚ climate‚ soil‚ light availability and intensity and natural disasters. The characteristics of the vegetation that are influenced by these factors are height‚ distribution‚ variety of species‚ adaptations and density of the vegetation. Some of these factors have relatively little influence on the succession development‚ whereas others have a dramatic influence over a long period of time‚ such as human activity. These factors

Determining Reference Ecosystems and the Historical Range of Variability Each and every year‚ trees record information within their growing rings and dendrochronology is the study of these tree-rings. Although tree-ring analysis is limited by the spatial scale of the climates where trees can grow and the temporal scale of the oldest possible age of a tree in a study area (183636 years ago)‚ it has proven to be a crucial tool in paleoclimatology and paleoecology. “To understand how ecosystems arrived at

Overpopulation of Humans The impact of human activity on the environment is catastrophically devastating and destructible. Assisting to that destruction is the increasing number of people that make up the worlds population today. Overpopulation is the condition of giving birth to a number of people living on earth that over exceeds the amount of space‚ resources and land found on our planet. According to reports from the United Nations (2007)‚ “World population is currently growing by approximately

What are Impact and Non-Impact Printers? A printer is an output device that prints characters‚ symbols‚ and perhaps graphics on paper. The printed output is generally referred to as hardcopy because it is in relatively permanent form. Softcopy refers to temporary images such as those displayed on a monitor. Printers are categorized according to whether or not the image produced is formed by physical contact of the print mechanism with the paper. Impact printers have contact; nonimpact printers do

ABSTRACT The main objective of this essay was to evaluate the impact of dams on the economic‚ social and environmental contexts. The idea was to analyse the dam’s major impact on each of these aspects. In the economic background‚ the benefits that hydroelectric dams provide were discussed in addition to the dam’s economic role in agriculture and food supply. Next‚ social impacts of dams were assessed which were mostly negative that dealt with population displacement and cultural sites destruction

The Effects of Foreign Species Introduction On An Ecosystem The effects of foreign species introduction into an ecosystem are very profound. From small microorganisms to species of large mammals‚ many foreign species introductions occur every day. New implications of their introduction are found just as often. When a foreign species is introduced into an ecosystem‚ often the ecosystem contains no natural predators for the new species. This lack of predators sometimes leads to; in conjunction
