Illinois Ecosystems All organisms need a few basic things to survive: food, water, shelter, and space. A habitat is the place where individual organisms or species live. An ecosystem is a community of plants, animals, and other organisms that interact with each other and the physical environment. Together they form an ecological unit which is largely self-contained. Each individual depends on other members of the system in order to survive. The subtle balance that ecosystems require in order to function properly is often impacted by a variety of natural and human influences including: destruction of habitat, habitat fragmentation, pollution, and introduction of non-native species. When ecosystems change, either naturally or as the result of human intervention, the survival of certain organisms within the system can be affected. According to the Illinois Critical Trends Assessment Project (CTAP), there are five major natural ecosystems in Illinois: Prairies, Wetlands, Forests, Rivers and Streams, and Lakes. Two other human-made ecosytems, urban areas and agricultural areas, are also prevalent in Illinois. Many smaller, more specific ecosystems can be found within larger ones.

Security Industry Search: Stories Headlines Writer Photos Search Science RSS Feed Nitrogen runoff is threatening ecosystems Published: March 12, 2008 at 3:16 PM Print story Email to a friend Font size: OAK RIDGE, Tenn., March 12 (UPI) A U.S. study suggests the increasing nitrogen runoff from urban and agriculture land-use is interfering with natural processes that protect ecosytems. The study said the increasing nitrogen runoffs prevent streams and rivers from naturally reducing the pollutant before it endangers delicate downstream ecosystems. Researchers said the findings are based on a major study of 72 streams in eight regions across the United States and Puerto Rico. "They (the waterways) are effective filters that can help prevent nitrate pollution from reaching lakes and coastal oceans, where it can cause noxious algal blooms and lead to oxygen depletion and death of fish and shellfish, as has been recently reported in the Gulf of Mexico," said lead author Patrick Mulholland of the Oak Ridge National Laboratory and the University of Tennessee. The study that included scientists from the Marine Biological Laboratory, the University of Georgia, Michigan State University, the University of Wyoming, the University of Notre Dame, Oregon State University, the University of New Mexico, Kansas State University, Arizona State University, the U.S. Forest Service, the University of New Hampshire, Virginia Tech and Ball State University appears in the journal Nature.

Credit: USFWS The planet is warming, humans are mostly to blame and plants and animals are going to dramatic lengths to cope. That's the consensus of a number of recent studies that used wildlife to gauge the extent of global warming and its effects. While the topic of climate change is contentious including whether the planet is actually heating up a growing number of documented shifts in traits and behaviors in the wild kingdom is leading many scientists to conclude the world is changing in unnatural ways. Among the changes [ see full list Marmots end their hibernations about three weeks earlier now compared to 30 years ago. Polar bears today are thinner and less healthy than those of 20 years ago. Many fish species are moving northward in search of cooler waters.

An ecosystem is a community of plants and animals that live together. South Florida is home to many different ecosystems including coral reefs dunes marshes swamps ... pinelands and scrubs What type of ecosystem will exist in a certain area is determined by how often fire occurs in an area, and changes in elevation (in some cases, only inches), water salinity (a measure of salt content), and soil type. Coral Reefs Over 30 different kinds of corals are found in Florida waters. Individual corals are interconnected colonies of soft, fleshy polyps that secrete complex shells made of calcium carbonate. These colonies can form branching corals or massive head corals depending on species. As the colonies compete for space, and as dead colonies are replaced, they grow on top of each other and build what we call a coral reef. Coral reefs provide habitat for thousands of species of plants and animals. Corals that grow in sunlit areas depend on tiny algae called zooxanthellae that live in their soft tissue. The zooxanthellae help provide oxygen and food for the polyps. Corals that live in deep water, where there is no sunlight, do not have zooxanthellae.

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). Central to the ecosystem concept is the idea that living organisms are continually engaged in a set of relationships with every other element constituting the environment in which they exist. The human ecosystem concept is then grounded in the deconstruction of the human/nature

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.
