62. Rec.gardens.ecosystems: Organic Gardening Based On Ecology rec.gardens.ecosystems is a moderated newsgroup. The group is dedicated to discussions of how to cooperate as a gardener with naturally occuring ecosystems http://www.ibiblio.org/rge/

About rec.gardens.ecosystems rec.gardens.ecosystems is a Usenet newsgroup intended for the discussion of gardening topics from an ecological perspective. In "down to earth" language, this means trying to work in concert with nature, rather than trying to force it into rigid format. A second aspect of the ecological perspective is that one avoids the use of toxic substances and fertilizers. Both toxic substances and fertilizers may seem to have short term beneficial effects on the home garden, but invariably turn out to disrupt the natural processes. The net result is that natures's dynamic balance is forced into a fixed balance, that can only be maintained by the use of more toxic substances and fertilizers. Gardening from an ecological perspective incorprorates organic gardening , and Integrated Pest Management (IPM) , but is not identical to either of them. What they have in common is that both can only be successful if based on a knowledge of how nature works. In accordance with this vision on gardening, rec.gardens.ecosystems is a moderated group. This means that there are a couple of people keeping a close eye on the group, and scanning potential contributions before they pop up in the group. This is mainly a preventive approach, enabeling us to keep the group free of the usual Usenet pests. More details on the group and its moderation policy are described in the charter and section A of the group's list of Frequently Asked Questions (FAQ). The other sections of the FAQ provide a growing body of knowledge on gardening from ecological principles.

72. 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.

Print Ecosystems of Costa Rica by Christopher Baker ; created 1995 In 1947, the biologist L.H. 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.

What is the future for the Tundra? - Sustainable Development Image provided courtesy of Jungle Photos ( www.junglephotos.com Image: A buttress root supporting a large tree in the Amazon Rainforest Introduction An ecosystem is a living community of plant and animals sharing an environment with non-living elements such as climate and soil. Ecosystems exist on a variety of scales. An example of a small scale ecosystem (micro) is a pond. A medium scale ecosystem (messo) could be a forest. The tropical rainforest is an example of a very large ecosystem (biome). Sunlight is the main source of energy. This allows the plant to convert the energy by photosynthesis. This allows the plants to provide food for some animals, birds and fish. These are called Herbivores. The other animals eat the animals that have eaten the plants. These are Carnivores. This process is called the FOOD CHAIN.

Real-Life Earth Science Vol 3 ECOSYSTEMS CONCEPT An ecosystem is a complete community of living organisms and the nonliving materials of their surroundings. Thus, its components include plants, animals, and microorganisms; soil, rocks, and minerals; as well as surrounding water sources and the local atmosphere. The size of ecosystems varies tremendously. An ecosystem could be an entire rain forest, covering a geographical area larger than many nations, or it could be a puddle or a backyard garden. Even the body of an animal could be considered an ecosystem, since it is home to numerous microorganisms. On a much larger scale, the history of various human societies provides an instructive illustration as to the ways that ecosystems have influenced civilizations. HOW IT WORKS T HE B IOSPHERE F OOD W EBS Food webs are built around the flow of energy between organisms, known as energy transfer, which begins with plant life. Plants absorb energy in two ways. From the Sun, they receive electromagnetic energy in the form of visible light and invisible infrared waves, which they convert to chemical energy through a process known as photosynthesis. In addition, plants take in nutrients from the soil, which contain energy in the forms of various chemical compounds. These compounds may be organic, which typically means that they came from living things, though, in fact, the term organic

The term ecosystem was coined in by Roy Clapham , to denote the physical and biological components of an environment considered in relation to each other as a unit. British ecologist Arthur Tansley later refined the term, describing it as the interactive system established between biocoenosis (a group of living creatures) and their biotope (the environment in which they live).

The Concept of the Ecosystem "I bequeathe myself to the dirt, to grow from the grass I love; If you want me again, look for me under your boot-soles." - Walt Whitman In this lesson, we will learn answers to the following questions: What is an ecosystem, and how can we study one? Is the earth an open or closed system with respect to energy and elements? How do we define "biogeochemical cycles," and how are they important to ecosystems? What are the major controls on ecosystem function? What are the major factors responsible for the differences between ecosystems? Format for printing Introduction - What is an Ecosystem? An ecosystem consists of the biological community that occurs in some locale, and the physical and chemical factors that make up its non-living or abiotic environment. There are many examples of ecosystems a pond, a forest, an estuary, a grassland. The boundaries are not fixed in any objective way, although sometimes they seem obvious, as with the shoreline of a small pond. Usually the boundaries of an ecosystem are chosen for practical reasons having to do with the goals of the particular study. The study of ecosystems mainly consists of the study of certain processes that link the living, or biotic, components to the non-living, or abiotic, components.
