LOG IN SEARCH GO USERNAME: PASSWORD: GO Ecosystems Ecosystem is a big buzz-word. Find out what all those buzzers are talking about with this BrainPOP movie on ecosystems! 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.

Heritage Community Foundation Presents Alberta Online Encyclopedia Home Ecosystems Choose a section! What is an Ecosystem? How Ecosystems Develop Changing Ecosystems Population Controls Food Webs Plant life What is an Ecosystem? Within all species , individuals interact with each other - feeding together, mating together, and living together. Some species have a pecking order as well, and each individual has a role to play within it. However, it is not only individuals within a species that interact. Different species of animals interact with each other all the time. For instance, animals eat other animals through their interactions in a food web . But plants are included in this web as well as they, too, are eaten by animals. What would happen if the weather were really cold all the time? Well, not all species of animals, plants and bacteria would be able to survive. What differences are there between species who live in the Rocky Mountains and those who inhabit the Sahara desert? Landscape also determines where plants and animals might live. But what, exactly, is an

A Brief Introduction to Ecology, from Earthtrust. HOW AN ECOSYSTEM WORKS: An ecosystem refers to all the living organisms and their non-living environment within a given area. Note that this definition includes two components; the living component which consists of the animals, plants and microbes, and the non-living component which refers to the air, water, rocks, soil and weather. There is no limit to how large or small an ecosystem can be. An ecosystem can be as large as an ocean or as small as a puddle. Very large ecosystems are known as biomes . An important point to recognize about ecosystems is the interaction between a grouping of plants and animals and their non-living environment and how the two strive to achieve a balance. Ecology relates to the study of ecosystems. Scientists who study the different components of ecosystems and how they are related to one another are called ecologists. Ecologists have determined that the populations of many species if left undisturbed by humans will remain relatively unchanged over time. Why then are so many species becoming extinct? Today, extinction rates are thousands of times greater than the natural rate. To better understand the reasons for this, it is first important to learn about the different factors affecting the living and non-living components of

Welcome to the Forest Ecosystem Dynamics (FED) Project WWW Server BACKGROUND INFORMATION. The Forest Ecosystem Dynamics (FED) Project is concerned with modeling and monitoring ecosystem processes and patterns in response to natural and anthropogenic effects. The project uses coupled ecosystem models and remote sensing models and measurements to predict and observe ecosystem change. The overall objective of the FED project is to link and use models of forest dynamics, soil processes, and canopy energetics to understand how ecosystem response to change affects patterns and processes in northern and boreal forests and to assess the implications for global change. See Conceptual Diagram for model schematic. The Forest Ecosystem Dynamics World-Wide-Web server has been online since July 1994. The FED server was created for the dissemination of project information, to archive numerous spatial and scientific data sets, and demonstrate the linking of ecosystem and remote sensing models.

Matt Edwards and Mike Foster Moss Landing Marine Laboratories P.O. Box 450, Moss Landing, CA 95039 I. Kelp Forest Distribution and Ecology A. Dominant species The rocky nearshore environment of the Monterey Bay National Marine Sanctuary (MBNMS), like the rest of central California, is characterized by dense forests of kelp growing at depths from 2 m to more than 30 m (Foster and Schiel 1985). The giant kelp Macrocystis pyrifera and the bull kelp Nereocystis luetkeana Along the central California coast where the distributions of these two species overlap, giant kelp outcompetes bull kelp for light. Giant kelp dominates areas of relatively low water motion, and is dominant in years with relatively calm sea conditions. Bull kelp is more tolerant of high water motion and dominates more exposed areas (McLean 1962, Foster 1982, Harrold et al. 1988). The shallow areas inshore of these kelp forests are often characterized by canopies of the feather boa kelp Egregia menziesii , the intertidal giant kelp Macrocystis integrifolia , and the Fucalean alga Cystoseira osmundacea (Foster and Schiel 1985).

This site is essentially a copy of the following unpublished thesis: Haydon, Richard J. 1997. The Concept of Naturalness in Natural Resource and Ecosystem Management MS thesis. Ellensburg, Washington: Central Washington University. This thesis examines what is meant by the term "natural," both in a general way and specifically within the context of natural resource management and the currently-popular "ecosystem management" paradigm. In addition to an extensive literature review, the project included a case study using the Delphi method, in which experts in various aspects of natural resource planning, research, and management participated in an effort to explore the full range of contemporary attitudes toward the concept of naturalness. Part B of the literature review should be especially relevant to those working in disturbance ecology or restoration ecology, while the case study results have their greatest implications for public land or natural area managers.

See the world (and its fossils) with UCMP's field notes. HOME SEARCH GLOSSARY ... Online exhibits The world's biomes Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment" ( Campbell 1996 ). The importance of biomes cannot be overestimated. Biomes have changed and moved many times during the history of life on Earth. More recently, human activities have drastically altered these communities. Thus, conservation and preservation of biomes should be a major concern to all. For further information, please consult the references page Here we group biomes into six major types: Freshwater Marine Desert Forest Grassland Tundra Conservation and preservation of biomes A coral reef surrounds an island in French Polynesia. Because we share the world with many other species of plants and animals, we must consider the consequences of our actions. Over the past several decades, increasing human activity has rapidly destroyed or polluted many ecological habitats throughout the world. It is important to preserve all types of biomes as each houses many unique forms of life. However, the continued heavy exploitation of certain biomes, such as the forest, freshwater, and marine, may have more severe implications. Forests are important as they are home to the most diverse biotic communties in the world. Hidden within these biomes are potential medicines and many thousands of unseen and undiscovered species. Also, forests have a global climate-buffering capacity, so their destruction may cause large-scale changes in global climate.

Welcome to the Buell-Small Succession Study! The BSS is a long-term ecological experiment designed to document succession on released agricultural fields. The study began in 1958 at the Hutcheson Memorial Forest in New Jersey and continues to the present. The BSS web site was developed as a resource for the public to learn about the study, for scientists to learn about current BSS projects, and to give scientists an opportunity to become collaborators on the project. Current Funding for the Buell-Small Succession Study is provided by grant DEB97-26993 from the National Science Foundation Long Term Research in Environmental Biology program.
