This page is an extract of a script that is part of the video series "The Living Landscape-an Australian Ecosystems Series". Visit all ecosystems. REEF ECOSYSTEMS A coral reef is composed of calcium carbonate, or limestone, derived from the water by the reef organisms: colonies of coral polyps and coralline algae. Most of this structure, the underlying foundation of the reef, is dead, made up of layer upon layer of coral skeletons. LIVING CORAL POLYPS The living reef is just a veneer, but it's this living part that continually adds new limestone to the massive base structure. Coral is the building block for this reef construction. Though coral looks like a plant, it's really an animal: or rather, a colony of animals that belong to the cnideria (the same group as jellyfish and sea anemones). There are a multitude of different kinds of coral, about 350 species including both hard and soft varieties, on the Great Barrier Reef. Their shapes are very different, and their colours come in the hundreds. SOFT CORAL HARD CORAL Coral animals are called polyps: tiny, primitive marine organisms. Each coral polyp is an individual organism, and the reef is made up of colonies of these organisms.

70. SeedTree USA campaign to preserve and renew forest ecosystems by developing a sustainable human ecology. News and details of programs. http://www.seedtree.org/

Our aim is to preserve and renew forest ecosystems by developing a sustainable human ecology. The worldwide losses of ecosystems and daily irreversible loss of species are among the most compelling issues of our time. In 1995, we gathered decades of combined expertise in forestry, renewable energy and human development, and founded SeedTree to face these urgent issues. Planting the seed of a tree begins restoring lands, forests, their biodiversity and the quality of life they provide. We started with a participatory program of indigenous seed collection and tree planting in communities around the endangered Chitwan ecosystem, central among the richly diverse forests at the foot of Nepal's Himalayas. As the links below reveal, we continue to develop components of a program that improves the quality of peoples' lives as it protects and renews their forests' health. We invite your participation in this vital life-enhancing effort. Your donation is tax-deductible and can be designated to support any of our programs.

Students will understand the following: Even a small area of land can offer wide biodiversity in plant life; that is, an ecosystem is composed of many different organisms. Each species of plant has its own name. Each ecosystem will contain evidence of diversity within each species. For this lesson, you will need: Access to an unmanaged part of the school grounds or of a local park Plastic bags for carrying leaf specimens Field guide to leaves Challenge your students to assess the biodiversity of their own community. Take them to a relatively unmanaged area of your property (or, for urban schools, to a local city park). Determine beforehand that the area does not contain any poisonous plants. Back in the classroom, make a list of the different leaves that were collected. (Naming the species is of secondary importance for assessing biodiversity, but it will be interesting to give your students the time and material to determine names of each plant.)

There has been a proposal to convert the US Environmental Protection Agency into a Cabinet office or Department of the Environment .

Ecosystems This map shows the eight biomes of the world. The orange area is tundra, purple is taiga, green is grassland, black is temperate forest, yellow is desert, blue is tropical rain forest, brown is chaparral and the white is ocean. Click on image for full size ( 84K JPG Windows Original Have you ever heard the word, ecosystem? Also called biomes, these regions of land make up the Earth's surface. All of the Earth's surface, with the exception of the ice in Antarctica and Greenland, fits into one of these ecosystems. But what is an ecosystem? An ecosystem is a region of land that has its own unique climate and life. The amount of rainfall, temperature and sunlight makes each region the way it is. Each biome is filled with plants and animals that have adapted to that land. All together, the land and its life is called an ecosystem. There are eight biomes in the world, and each one is different than the other. The first one is the ocean. This biome is the largest of all, since water makes up most of the planet. Rainforests are unique areas where strange animals thrive in the warm, wet climate. Colder areas that receive enough rain will see temperate forests form. If there isn't enough rainfall, grasslands will fill the region. Dry, hot regions will become desert, while the frigid cold regions of northern North America and Asia are called tundra. Taiga is the named given to land in between the cold tundra and the warmer temperate forest and grassland biomes. And finally, a very small amount of land in Europe and Australia is called Chaparral.

NOFRETETE Funded by the European Commission DG Research - V th Framework Programme in the thematic programme "Energy, Environment and Sustainable Development" , Key Action 2 "Global change, climate and biodiversity" Nitrogen oxides emissions from European forest ecosystems General information Contract N° Official commencement date Duration 3 years Coordinator Klaus Butterbach-Bahl The source strength of EU forests for the primarily and secondarily active N-oxides N O and NO is highly uncertain. However, recent investigations have shown that EU forests, due to high rates of atmospheric N-deposition in the last decades, are significant sources for N-oxides. Based on results obtained from field and laboratory experiments on the characterisation of N-oxide fluxes in different forests (e.g. climate, soil, forest type) we will further improve and validate a) a mechanistic model and b) a canopy exchange model for predicting N-trace gas emissions at the soil-atmosphere and canopy-atmosphere interfaces. After combination of both models, we will calculate EU wide inventories of N-oxide emissions from forests with hitherto unknown precision and, using scenarios for future changes in climate and N-deposition, predict future changes in N-oxide emissions.

Earth’s ecosystems and its peoples are bound together in a grand but tenuous symbiosis. An urban professional in Tokyo reads a newspaper printed on pulped trees from North American forests. Her food and clothing come from plants and animals raised around the world cotton and cashmere from Asia, fish from the Pacific and Indian oceans, beef from Australian and North American grasslands, fruits and vegetables from farmlands on four continents. The coffee she sips comes from tropical Central American plantations, but it brewed with water from wells near the city. We depend on ecosystems to sustain us, but the continued health of ecosystems depends, in turn, on our care.

Redistributed as a Service of the National Library for the Environment Ecosystems, Biomes, and Watersheds: Definitions and Use M. Lynne Corn Specialist in Natural Resources Policy Environment and Natural Resources Policy Division July 14, 1993 93-655 ENR SUMMARY Due to conflicts in many areas such as old growth forests in the Northwest, the Everglades in south Florida, Chesapeake Bay, and the Rio Grande watershed, many people are advocating a broader approach to management of land and water resources and biological diversity. They argue that existing laws run at cross purposes, or that the plethora of requirements under many laws and regulations means that no land use decision is ever final. As a result, and from a surprising range of philosophical platforms, many in Congress are advocating "ecosystem management" in various land use and conservation issues. Yet, there is little agreement, even in the scientific community, on the meaning of the term ecosystem. This paper describes the meaning and applications of ecosystem and of the related terms watershed and biome.
