Skip over navigation Home About GEO ... GEOSS SBA : Ecosystems Ecosystems Terrestrial, coastal and marine ecosystems provide essential socio-economic and environmental benefits. Ecosystems the world over, however, are under tremendous stress from rapid land-use change, pollution and the overexploitation of natural resources. Unfortunately, current Earth observation systems for monitoring forests, wetlands, deserts and other ecosystems suffer from numerous gaps and weaknesses. As a result, these systems cannot adequately support efforts to revive, protect or manage ecosystems. The Group on Earth Observations aims to strengthen ecosystem monitoring through the Global Earth Observation System of Systems. GEOSS will establish an expanded and coordinated network of land, ocean and coastal monitoring systems that will produce information of the required breadth and depth. In particular, GEOSS will improve spatial information on ecosystem conditions and trends. It will enable researchers to classify ecosystems and delineate their boundaries, including the geographic limits of protected areas. It will generate and integrate a wide variety of ecosystem data and create high-resolution maps so that decision makers can monitor ecosystem services such as flood control and sustainable timber harvests. GEOSS will also improve the monitoring and assessment of desertification and help to coordinate global, regional and national forest monitoring programs.

Senator Salazar Joins Other Senators in Calling for Adequate Funding of Endangered Species Programs Critterthink Blog Entry by Brian Hires on Wednesday, March 19, 2008 Through a Senate 'Dear Colleague' letter to Interior Appropriations Committee leadership last week, Senator Ken Salazar (D-CO) called for increased funding of endangered species programs. The President's '09 Budget calls for yet another funding cut to endangered species programs. Conservation of our nation's most imperiled wildlife and habitat has been severely hampered by the administration's ultimate trump card in its war against endangered species - withholding needed funding for endangered species programs.

45. 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.

Select your view An International Journal for Scientific Research on the Interaction Between Agroecosystems and the Environment Editor-in-Chief:* M.R. Carter See editorial board for all editors information Description deals with the interface between agriculture and the environment. It seeks to provide a science forum to discuss how agricultural practices influence the broader environment and how changes outside agriculture affect agricultural systems. Emphasis is placed on innovative and original research that elucidates the link between agroecosystems (association of crops, pastures, livestock) and the environment (including energy, air, water, land). This two-way interface or link cuts both ways as it elucidates the influence of agriculture on the environment but also characterizes how changes in the latter impact agroecosystems. The journal covers topics such as ecology of agricultural systems; response of agroecosystems to environmental stress (climate change, intensification, soil degradation, pollutants, waste materials, air quality, and changing land and water use); agricultural landscape ecology and processes; and characteristics of agroecosystems from a biological, physical, and environmental standpoint. Papers that advance our understanding on how to make agroecosystems more diverse and sustainable are especially welcome.

Prairie Profiles The Prairie Ecosystem The North American prairie is one of the most endangered ecosystems on earthperhaps even more endangered than the South American rain forest or the old growth forests of the American northwest. The grasslands of North America began to form about 20 million years ago, but in some areas, up to 99 percent of the prairie has been destroyed in just the last 125-150 years. The formation of the prairie The area known as the Great Plains was once the greatest grassland on earth and covered over a quarter of the continental U.S. along with portions of southern Canada and northern Mexico. The prairie stretched from the Rocky Mountains eastward for over 800 miles, and extended more than 3000 miles from north to south. The plains were created from sediment washed out of the Rockies over millions of years which mixed with rubble from glaciers, and windblown deposits of silt, sand and clay which now rests on the bed of what was once a shallow inland sea. The Rocky Mountains also intercepted the flow of moist air from the Pacific, and dried out the interior of the continent, which favored grasses over trees. Receding glaciers formed thousands of shallow depressions across the Northern Plains. These wetland areas, known as prairie potholes, range in size from 1/5th of an acre to 25 acres. Cattails and rushes comprise the dominant emergent plants, and floating plants such as water lilies and duckweed are also common. Although the pothole region comprises only 10 percent of North America's waterfowl breeding areas, it produces over half of the continent's duck population. Besides serving as breeding and watering sites for wildlife, potholes collect rain and flood waters, which are released slowly, helping prevent floods and erosion. Today, many areas of prairie potholes have been drained, primarily to create farmland.

Home Field Sites Teacher Resources Student Activities ... South Florida Rockland People have been interacting with and modifying Florida's ecosystems for at least 10,000 years. Over most of this time their use of natural resources was sustainable. Their activities did not cause any significant decrease in the ability of the environment to maintain clean air and water, as well as productive, biologically diverse ecosystems. However, the massive human uses of Florida's natural environment in the twentieth century are clearly unsustainable. Deforestation in the north, wetland drainage in the south, agriculture in the center, and creeping urbanization everywhere have caused massive losses of natural ecosystem diversity and productivity. Perhaps the major challenge of the next century is to create an environmentally, as well as economically, sustainable way of living. The collective properties managed by public agencies and private groups, such as national forests, state parks, and private refuges, form a fragmented but extremely important Nature Reserve System of Florida. Enlarging and/or connecting these fragments into a more integrated and comprehensive protected area system is a critically important goal of the next decade but will not by itself suffice to maintain the existing biodiversity of Florida. In addition, human activities in the vicinity of reserves should contribute to protection of biodiversity in the reserves, and Floridians everywhere must live in closer harmony with their natural heritage.

59. MICRO-ECOSYSTEMS The Microecosystem activity/project can be used during an ecology unit and can be adapted to a variety of classes and students. http://www.accessexcellence.org/AE/AEC/AEF/1996/doerder_micro.html

-Advertisement- MICRO-ECOSYSTEMS by Nora C. Doerder Type of entry: Long term project Type of Activity: hands-on Authentic assessment group/cooperative learning off-site review/reinforcement Target Audience: Biology Advanced/AP biology Environmental studies Special needs Background Information The Micro-ecosystem activity/project can be used during an ecology unit and can be adapted to a variety of classes and students.It is best to set up the ecosystems early in the school year and to construct them following a field trip. A pond or wetland can provide good sources of "starter" mud and water. Students design an aquatic or terrestrial micro-ecosystem or model local ecosystems in 10 gallon aquarium tanks. The project may take from one to three weeks depending on the amount of time available for lab and how involved the project becomes. Observations on the micro-ecosystems occur over the school year, and the tanks are left until fall for initial study by a new class. Opening the micro-ecosystems provides materials for labs that may include: doing a biological survey utilizing dichotomous keys, reviewing/studying the five kingdoms, practicing basic microscope techniques, creating microbiological cultures or Winogradski columns. The organisms and materials from the previous year's projects are recycled in the new projects. The micro-ecosystems also include time capsules. The tanks should be near windows but generally do best with lower levels of light (less chance for a green house effect to cook the interior). The outside designs that students paint also help control light levels. It is possible to stack the tanks with boards and cement blocks or on aquarium stands.
