Abstract
This paper examines the spread of invasive plant species, specifically in the United States, and explains the nature of some of these invasive species. The writer discusses how these plants are introduced to the United States, their negative effects on the environment, and methods of control. The The writer also discusses the leading hypothesis for how nonnative plant species become invasive, known as the "escape-from-enemy" hypothesis. The paper concludes that more education and awareness is needed in order to fight these invasive species which have the potential to destroy native ecosystems.

From the Paper
"Invasive plants are a major, if not well understood, threat to ecological stability in the United States if not the world. Some nonnative species that are introduced into a new habitat are entirely innocuous and have no detrimental effects. Others are ill-suited to the new environment and quickly expire. Some, however, are exceptionally well-suited for their new place in the world and quickly overcome all of the native species. The kudzu vine and the zebra mussel are examples of such aggressive, invasive species. Unfortunately for those environmentalists and social agencies interested in preventing the spread of invasive species, the attributes of a successful invasion are not well understood (Wolfe 705). Understanding how nonnative species become invasive must be one of the first priorities in the fight against their spread and the subsequent destruction of ecosystem stability."

Abstract
This paper analyzes Shakespeare's "First Sonnet" and in particular shows how the connotations behind the words to people living in Elizabethan England makes Shakespeare choice of imagery start to take on a far deeper meaning. It examines Shakespeare's ties to the land since from the first line to the fourteenth, Shakespeare infuses the poem with meaning with the use of agricultural terminology that everyone in his day would have been familiar with and how by employing the farming metaphors and the references to spring and to the harvest, he can't help but remind the Elizabethan reader of the march of time.

From the Paper
"While we know that fairest often refers to beauty even though it is antiquated, it would have been quite natural for that era's farmers in their effort at selective breeding to encourage and even expect that the fairest of their creatures would breed. It was paramount to their success for their best horses to foal, their sturdiest cattle to multiply. In that sense, the best and the beautiful have an obligation to mate and pass their genes on to their heirs, and so too, according to Shakespeare, did a young man have that responsibility as well."
