The Coniferous Forest Biome Ecosystems The plants and animals that are found in a particular location are referred to as an ecosystem. These plants and animals depend on each other to survive. In a delicate balance, these life forms help to sustain one another in regular patterns. Disruptions to an ecosystem can be disastrous to all organisms within the ecosystem. As an example, consider what happens when a new plant or animal is introduced into an ecosystem, where it did not before exist. The new organism competes with the natural organisms from that location for available resources. These unnatural strangers can push other organisms out, causing them to become extinct. This can then effect still other organisms that depended on the extinct organism as a source of food.

23. Ecosystems ecosystems are as varied as the meadows, glaciers, rivers, canyons and other resources that make up the National Park Service landscape. http://www.nps.gov/gis/mapbook/ecosystems/ecosystems.html

National Park Service Use of GIS to Manage Ecosystems Ecosystems are as varied as the meadows, glaciers, rivers, canyons and other resources that make up the National Park Service landscape. The primary resource of an ecosystem might be a lake, forest, desert, or a particular endangered plant or animal. This makes ecosystems hard to define. They often include complicated relationships between physical, biological and cultural resources. And federal law requires the National Park Service to preserve ecosystems that often extend beyond protective park boundaries. Within this realm, GIS is a great tool to understand ecosystems and their importance in our world today. The mapping function of GIS illustrates the relationships between individual parts of the ecosystem, such as a particular wilderness and the wildlife found there. This high-tech tool does simple jobs, such as measuring areas and distances, or more complex tasks involving many variables within an ecosystem. GIS software can produce models that show the slope of land, precipitation, the kind of soil, and help us understand their impacts on the ecosystem. A GIS can illustrate the relationship of an ecosystem to other areas and lets researchers monitor changes that take place over time. Animations or time-series maps offer convincing, understandable evidence when these changes happen. This wealth of information has helped the National Park Service do a better job as it preserves our parks. With help from GIS, park managers can study and react to potential environmental threats against a park that come from the outside. Using GIS, a park manager might propose extending park boundaries to include resources deemed critical for the health of an ecosystem. More frequently, it helps the National Park Service monitor ecosystems as part of its goal to preserve our natural wonders.

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.

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.

Check out: X8: Eco-Cycle Preserving Biodiversity Creative Climates Weather Complaints ... Biomagnification in the Great Lakes Ecosystems However, the stability and balance of ecosystems can be altered by large-scale natural events such as El Niño, volcanic eruptions, fire, or drought. But ecosystems are more drastically transformed by human activities. The web of ecological interdependency is fragile. Human intervention can shatter the balance of energy production and consumption. For example, the overgrazing of pasture lands, coupled with a period of drought, can lead to vegetation loss, the exposure of topsoil, layers, and massive soil erosion (as occurred in the 1930s Dust Bowl); tropical forest clear-cutting can lead to soil erosion and ecological breakdown, as is currently occurring in Amazonia; the construction of oil pipelines in tundra environments can threaten the movements of the caribou herds on which indigenous Inuit populations depend. By knowing how ecosystems operate and change, students are able to understand the basic principles that should guide programs for environmental management. Students can understand the ways in which they are dependent on the living and nonliving systems of Earth for their survival. Knowing about ecosystems will enable them to learn how to make reasoned decisions, anticipate the consequences of their choices, and assume responsibility for the outcomes of their choices about the use of the physical environment. It is important that students become well-informed regarding ecosystem issues so they can evaluate conflicting points of view on the use of natural resources. The degree to which present and future generations understand their critical role in the natural functioning of ecosystems will determine in large measure the quality of human life on Earth.

Who's who in ecosystems: Ecosystem: An array of organisms and their physical environment, all of which interact through a one-way flow of energy and a cycling of materials. Most of the energy originally fixed by the autotrophs is lost to the environment as metabolic heat. 1. Producers : autotrophic ("self-feed") organisms; produce the carbon and energy they need. Examples: photoautotrophs (plants, plankton) and chemoautotrophs (sulfur bacteria) 2. Consumers: heterotrophic organisms; obtain energy and carbon by feeding on the tissues of other organisms. Herbivores, carnivores, and parasites are examples. Herbivores: eat plants Carnivores: eat animals Omnivores: eat 'a variety of edibles' = plants animals, etc

Contact Us Ecosystems Group T he primary aim of the Ecosystems Group is to study the ecological components of arctic and alpine systems and their interactions with climatic and biophysical variables. The Ecosystems Group has recently expanded to include study of the tropics and human dimensions. Basic research topics include: ecosystem dynamics biogeochemical processes biodiversity ecosystem disturbance and recovery modeling of biotic pattern distribution ecological assessments conservation planning We address questions of how climatic influences, biophysical factors, and biotic components interact to control the distribution and maintenance of ecosystems; how the hierarchical organization of current ecosystems was produced in response to past and present environments; how predicted climatic changes and current and future changes in land-use patterns will affect ecosystems; and how conservation planning can contribute to sustainable ecosystems at multiple geographic scales. Ongoing projects investigate the following characteristics and scales of ecological systems: populations, species, communities, landscapes, and regions; plants and animals; biogeochemistry, ecophysiology, hydrology, patterns of biotic distribution, and biogeography; and above- and below-ground systems.

USGS: Biology Ecosystems Home Welcome to the USGS Terrestrial, Freshwater, and Marine Ecosystems Program Civilization depends on life-support services that natural ecosystems perform, including regulating climate, mitigating floods and drought, protecting shorelines from erosion, purifying air and water, detoxifying and decomposing wastes, and pollinating crops and natural vegetation. Healthy ecosystems provide habitat for diverse fish and wildlife communities. Studies conducted by USGS Terrestrial, Freshwater, and Marine Ecosystems scientists describe factors that control ecosystem structure, function, condition, and the provision of goods and services. This information is used to predict future changes to ecosystems and to describe the results of management alternatives. Ecosystem science is thus used to restore degraded landscapes and freshwater systems, sustain plants and animals, and find means to adapt management to global change.
