ECOSYSTEMS AT RISK – CASE STUDY 2 PART 1: CORAL REEFS – OVERVIEW Coral reefs are often referred to as “the rainforests of the sea” because of they form some of the most diverse ecosystems on Earth. Its massive structure is formed from coral polyps (tiny animals that live in colonies) that support approximately 25% of all known marine species by providing essential habitats. Factors affecting reef development and survival include temperature‚ light‚ sedimentation and salinity of the water. Without

The Natural Ecosystem of the Panama Canal The Ecosystem of the Panama Canal has gone through many changes over the years since its development. Before the canal was created it was part of a lush and dense rainforest that was full of different species of plants and animals. Around the 16th century a plan was devised to make a passage along the Isthmus of Panama back around 1513 by Vasco Nunez de Balboa when he discovered a narrow strip of land that could connect the Atlantic and Pacific oceans

This report deals with the study of an ecosystem group and a major functional role within it. The components of the role and other factors such as relationships within the ecosystem are discussed along with quantitative data and examples. The ecosystem group chosen is a local‚ coastal ecosystem called the Barker Inlet – St Kilda Aquatic Reserve and the Torrens Island Conservation Park. Together we have termed them the Barker Inlet Mangrove Ecosystem which is situated approximately 20 kilometres

The most frequent accessory artery is a polar artery arising from the aorta‚ close to the origin of the main renal branch‚ and supplies the inferior renal pole. The second most frequent supplementary artery irrigates the upper pole‚ which is normally a small segment [40]. Some authors call polar arteries those that attain any of the kidney poles with independence of its origin. It
