Holdridge introduced a system of classifying vegetation types or "zones" according to a matrix based on analyzing combinations of temperature, rainfall, and seasonality. Each zone has a distinctive natural vegetation and ecosystem. Costa Rica has 12 such zones, ranging from tidal mangrove swamps to subalpine with its stunted dwarf plants above the timberline atop the high mountains. Costa Rican Natural History, edited by Daniel Janzen, provides a description of the vegetation types associated with each life zone. You can also obtain a life zone map from the Tropical Science Center (Calle 1, Avenidas 4/6), a private nonprofit organization which operates the Monteverde Cloud Forest Reserve.

Ecosystems Ecosystems (short for ecological systems) are functional units that result from the interactions of abiotic, biotic, and cultural (anthropogenic) components. Like all systems they are a combination of interacting, interrelated parts that form a unitary whole. All ecosystems are "open" systems in the sense that energy and matter are transferred in and out. The Earth as a single ecosystem constantly converts solar energy into myriad organic products, and has increased in biological complexity over time. feedback of cybernatic system that reflects what Rene Dubos referred to as "a co-evolutionary process" between living things and their physical and chemical environments. Ecosystem is made up of many smaller ecosystems interlocked through cycles of energy and chemical elements. The flow of energy and matter through ecosystems, therefore, is regulated by the complex interactions of the energy, water, carbon, oxygen, nitrogen, phosphorus, sulfur, and other cycles that are essential to the functioning of the biosphere. (Eblen and Eblen, 1994, p. 185)

An Ecological System The word ecosystem is short for ecological systems. An ecosystem includes all of the living organisms in a specific area. These systems are the plants and animals interacting with their non-living environments (weather, Earth, Sun, soil, atmosphere). An ecosystem's development depends on the energy that moves in and out of that system. As far as the boundaries of an ecosystem, it depends upon how you use the term. You could have an entire ecosystem underneath a big rock. On the other hand, you could be talking about the overall ecosystem of the entire planet (biosphere). An ecosystem can be as small as a puddle or as large as the Pacific Ocean. That ecosystem includes every living and non-living thing in the area. It is several small communities interacting with each other. Let's look at a puddle example. You might start by looking at the temperature, depth, turbulence, sunlight, atmospheric pressure, weather patterns, wind, nutrients, etc. Those are just the non-living things in the ecosystem of a puddle. When you add on all the living interactions, you have a good idea how complex an ecosystem can be. Even a puddle is an amazing place. Biomes Scientists discuss some general ecosystem types. They call them biomes. A biome is a large area on the Earth's surface that is defined by the types of animals and plants living there. A biome can be partially defined by the local climate patterns. You may also have more than one type of biome within a larger climate zone. Here is a short list of possible biomes.

In it, Tim and Moby explain what an ecosystem is and what makes one up. For instance, you’ll learn what communities, populations, and habitats are, and why animals tend to be well-adapted to their environment — like desert species being well-adapted to hot, dry, conditions, while species living in the taiga are well-adapted to the cold.

30. Ecosystem Approach - U. S. Fish And Wildlife Service Ecosystem Approach in the US Fish and Wildlife Service. http://www.fws.gov/ecosystems/

Ecosystem Conservation What is an ecosystem? It is a geographic area including all the living organisms (people, plants, animals, and microorganisms), their physical surroundings (such as soil, water, and air), and the natural cycles that sustain them. All of these elements are interconnected. Managing any one resource affects the others in that ecosystem. Ecosystems can be small (a single stand of aspen) or large (an entire watershed including hundreds of forest stands across many different ownerships). What is a watershed? A watershed is the total land area from which water drains into a single stream, lake, or ocean. Why work on ecosystems? The U.S. Fish and Wildlife Service has adopted an ecosystem approach to conservation because we can't just look at a single animal, species, or piece of land in isolation from all that is around it. We all realize that we are not going to achieve conservation within the boundaries of a National Wildlife Refuge, that we are not going to restore aquatic resources with a National Fish Hatchery, and that listing an endangered species is not going to conserve the system. All of these are interconnected. If we disturb or manage one, all of the others will be affected. The ecosystem approach is comprehensive. It's based on all of the biological resources within a watershed and it considers the economic health of communities within that watershed.

Contact Us It is clear that the fate of the natural landscape depends not only on individual people, but on the coherence and vitality of the communities to which they belong and the means they develop for negotiating the relationship with the biotic community. -William Jordan III Welcome Memorial Ecosystems Inc. opened Ramsey Creek preserve in 1998, the first “green cemetery” in the United States. The preserve was formed to harness the funeral industry for land protection and restoration, to fund non-profits, education, the arts and scientific research, and to provide a less expensive and more meaningful burial option. Our award-winning company aspires to protect, restore and permantly endow one million acres of wild-lands over the coming decades. More than merely financing protection, the inherently spiritual nature of our endeavor means that we can foster closer ties between human communities and the natural communities that they depend on. Our main focus is to develop multi-functional memorial nature preserves that we create with the cooperation and assistance of non-profit organizations. Through becoming members of the preserve during life, and choosing burial in the preserve after, our clients leave a permanent legacy for their families, their communities and the natural world. We are committed to being the leaders in environmentally and socially responsible death care.

Coastal ecosystems are those found from coastal watersheds to the outer boundary of the U.S. 200 mile Exclusive Economic Zone (EEZ). These ecosystems include coastal estuaries (including the subset of National Estuarine Research Reserves), coastal areas under protected under the National Marine Sanctuaries, and coral reef ecosystems. CSCOR sponsors research across all of these coastal ecosystems. Coastal Oceans The coastal ocean encompasses a broad range of saltwater ecosystems, including estuaries, coral reefs, rocky shores, gravel shores, sandy shores, mud flats, marshes and mangrove forests.
