University’s Successional Plot’s Soil P.H. Meredith Hamilton Biology- Westover September 30‚ 2011 Abstract The question of this study pertained to the amount of vegetation that was occurring on each of the succession plot’s ground floor. There are three successional plots in Winthrop University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to test the amount

A Culturally Endangered Youth. Introduction The combined forces of colonialism‚ westernization‚ and modernization have perfectly combined to drive Igbo culture to the margins of existence. What is dominant among the Igbo now is the payment of lip service to culture‚ especially by way of tourism and so-called inculturation. The people most affected are the young ones‚ mainly because the usual framework of learning by participation is no longer available to a greater percentage of them. Since the

Soil degradation refers to the decline in quantity and quality of soil. Degradation of soil is done by erosion (wind and water)‚ biological degradation‚ physical degradation (referring to the over loss of structure and changes in permeability) and chemical degradation‚ this refers to acidification‚ declining fertility‚ changes in pH levels‚ salinization and chemical toxicity. Soil degradation affects not only the environment but also the economy as well as people. The effect that soil degradation

undertake‚ particularly for a group of students with nothing but a shovel. The soil here is hard and compact‚ full of pebbles and lava rocks. Attempting to dig a pit would have been toilsome and ultimately fruitless. Fortunately‚ while on a fieldtrip‚ my classmates and I came upon an archaeological dig site. It was basically a big pit‚ about five feet deep‚ that was perfect for our observations. There were obvious changes in the soil through the different levels‚ and the archaeologist on location provided

2. METHODOLOGY AND DATA 2.1 Holdridge Life Zones In Holdridge (1967) life zones approach (Figure 1)‚ there two assumptions: 1) The temperature and precipitation variables are main factors determining life zones (or biomes). 2) The vegetation is assumed to be independent of animals. According to the assumptions‚ the primary influences on life zones are those factors that make up climate of the Holdridge system. In this respect‚ it is not unlike the systems of Köppen (1931) and Thornthwaite (1948)

Public Understanding of Climate Change in the United States Elke U. Weber Paul C. Stern Columbia University National Research Council This article considers scientific and public understandings of climate change and addresses the following question: Why is it that while scientific evidence has accumulated to document global climate change and scientific opinion has solidified about its existence and causes‚ U.S. public opinion has not and has instead become more polarized? Our review supports a constructivist

The most commonly overlooked form of sexism is the “Friend-zone”‚ a manifestation of misogynistic ideology created by vapid petulant men who refuse to take “no” for an answer‚ and is used as an excuse for aggressive male dominance as well as sexual and domestic violence. According to the friend

The first is labelled as Valley A‚ and was obtained from a field which has been known to be uncultivated for 10 years in the valley. Valley B was obtained from a domestic garden‚ under a Magnolia tree in the same region. At times when a third sample was tested‚ the source will be indicated. Soil texture
