Marine Ecosystems are the largest systems on the planet‚ covering over 70 percent of the Earth’s surface and constituting over 99 percent of the living space on the planet (area x depth). These vast ecosystems are composed of many different habitats which extend from the near shore regions to continental shelves and the deep ocean. They are home to millions of species and provide food‚ income‚ protection‚ and many other vital ecosystem services to billions of people around the world. ECOLOGICAL

Ecosystem Composition of the Valdivian Temperate Rainforest One of the world’s largest temperate rainforests is the Valdivian Temperate Rainforest (Wade et al. 2008). The Valdivian Temperate Rainforest ranges along the Pacific coasts of southern Chile and Argentina in South America‚ between 36 and 47° S latitude. This forest occurs in the temperate broadleaf and mixed forests biome (Perry et al. 2008). The broadleaf evergreen flowering trees that dominate the Valdivian are believed to have evolved
