(a)The species have been carried by marine trade on the hulls of ships and in bilge and ballast water and the movements tend to be between developed areas, reflecting trade patterns. Some areas are not involved; these tend to have less trade. There may be some specific knowledge of individual species from Figure 3 which should be credited, as should other species not shown on Figure 3 (rats). The major disruption is to food chains, as the alien species out-compete existing species reducing their

Ecosystem Structure, Function, and Change Hector Canseco SCI/256 04/30/2015 Carolyn Miller Freshwater Ecosystem is a relatively small in area about 1.8% of the earth’s surface. It consists of ponds and lakes which range in size from just a few square meters to thousands of square miles. All throughout the earth several are remnants from glaciers thousands of years ago. Many ponds are seasonal, lasting just a couple of months while lakes may exist for hundreds of years or more. Ponds and

There are two types of grasslands, tropical and temperate. Tropical grasslands are warm year around and have a dry and rainy season. Temperate grasslands have an average of 10 to 30 inches of rain per year, have shorter grass, and have a growing and dormant season (Grasslands Terrain of Many Names). There are the Great Plains in the United States that cover from parts of Texas, New Mexico, Oklahoma, Colorado, Wyoming and Montana and covers all of Kansas, Nebraska, South and North Dakota, and covers

Wetlands are saturated land areas consisting of marshes or swamps. Louisiana’s wetlands make up of about 40% of the continental wetlands. Wetlands have a very large impact on Louisiana, such as the culture because some of our culture is dependent on the wetlands and the protection that the wetlands give us from and during the hurricanes. That protection isn’t going to last very long because of the species, that are continuing to ruin the land and by eating the wetlands and the amount of recreational

Marine Biomes Shonda Morton October 20, 2013 SCI/230 Paula Roberts A marine biome is a large aquatic zone that takes up almost 75% of Earth’s surface, has a salt concentration around 3%, and is distinguished from other biomes by its physical environment. According to Campbell Essential Biology with Physiology, (2010), the habitats of a marine biome varies depending on the level of the sea that it exists (pp.382). The layers or “zones” that make up the marine biome consist

Tundra Biome The arctic tundra is the worlds youngest biome. it contains the last set of continental glaciers from about 10,000 years ago. As the glacier went away it scraped away the soil from underneath, leaving bare rock. Before plants were able to grow the arctic tundra had to develop soil. Soil forms very slowly on the tundra because the cold weather slows the rate at which chemical reactions occur. Only a thi layer of soil has formed in the thousands of years since the glaciers retreated

Dear Ms. Roberts, It is currently the summer of 2016 and I have just arrived in Brazil to watch the summer Olympics with my beloved, British boyfriend Harry Styles. Harry was invited to perform at the opening ceremonies here in Rio de Janeiro with his band, so I decided I would come with him and research the Tropical Rain Forests. The thing most different about rain forests compared to South Dakota is the fact that they are warm year-round. In fact, rain forests go through virtually no season

The Fynbos biome is the name given to the indigenous vegetation that puts the garden. Many plants that are popular worldwide today had their origins in the fynbos biome. Many fynbos species are typically confined to acidic nutrient-poor sandstone soils. Fynbos is the name given to a type of vegetation. It is a shrubby, hard-leaved, evergreen type of vegetation. Fynbos is characterized by the presence of reed-like plants. Fynbos makes up sixty seven percent of the fynbos biome. It is the vegetation
