American Prairies: Change in Ecosystem Structure and Function Introduction Stretching approximately two million acres of land‚ the North American Prairies cover a large portion of the continent. From Montana to Oklahoma to Colorado and to the provinces of Alberta‚ Manitoba‚ and Saskatchewan in Canada‚ the Great Plains‚ having moderate temperatures and suitable rainfall conditions‚ provide a valuable resource to society. Due to the expanse of land and the varying habitats within the prairies ecosystem

on the succession development‚ whereas others have a dramatic influence over a long period of time‚ such as human activity. These factors‚ over time‚ result in the progression of a succession until the climatic climax vegetation is reached. However‚ sometimes these factors can mean that a plagioclimax is reached‚ as they prevent the succession from progressing any further and the climatic climax vegetation is never achieved‚ which in the UK are Oak‚ Hawthorne and Birch trees. This succession results

Lake Tahoe is one of America’s deepest‚ freshwater lakes. The iconic vacation spot keeps locals and tourists occupied with ski resorts and casinos. Although‚ there is more to the area than its breathtaking views. The Lake Tahoe Basin is home to many species that contribute to its ecology.
