Home About MESA Contact MESA Seaweek ... Forums Habitats - Kelp Forests Kelp Forests The information presented here has been written by staff at the Marine Discovery Centre, Queenscliff, Victoria. 1. Distribution Kelp forests are a feature of many cool water environments around the world and Australia supports some excellent examples of these forests of the sea. Kelp forests are also a feature of the west coast of North and South America, the north west Pacific including Korea, New Zealand, South Africa, and many of the islands in the Southern Ocean. Kelp forests usually grow on subtidal rocky reefs although some kelps are able to grow on smaller scattered rocks. In general they grow on reefs in waters to a maximum of around 30 metres depth, although most are found in shallower waters. These areas can also extend onto the shore where a rock platform is in the intertidal area with larger kelps only growing up to the low tide mark. Snorkelling in a forest of Giant String Kelp. Giant string kelp Macrocystis angustolia As these plants are found in cool water extensive kelp forests are only found in Southern Australia, and they are particularly diverse in Victoria and Tasmania. Some species can grow to lengths of over 30m and can been seen with their fronds extended across the water surface.

I was surprised, humbled and overwhelmed! I'm glad so many people find this page useful. Still..... This page has become a kind of backwater in our own web; we have a lot of NEW features that might be of interest to students and educators alike. Feel free to use these resources and link to them; just be sure to mention Marietta College so I can convince the Dean and the IT people why I need so much space on the server. In any event, you may want to check out these links: Marietta College's Biomes of the World - all the information on this page (check out the ecology pages) plus maps, climate diagrams and photos of biomes the world over. Each biome description includes sections on climate, distribution, indicator plants and animals, ecology, threats and a tour of the biome.

What's This? Let's help save our planet by maintaining our ecosystems. ULTRA.F/Digital Vision/Getty Images For the past several years, you've likely heard a lot about saving our planet and our ecosystems on television and in movies. Perhaps you haven't really given it much consideration. But you should. As the human population increases, the strain on our ecosystems also increases, which means that our survival is threatened. Maintaining our ecosystems is crucial to ensure our survival, our children's survival and our grandchildren's survival. Difficulty: Moderate Instructions Practice and promote conservation. Conservation is the protection of a natural resource, such as a lake, or a species so that it isn't harmed or eliminated. Conservation maintains our ecosystems by promoting biodiversity. You can practice and promote conservation by doing things like joining a group that helps limit the commercial use of an area or by educating others about the importance of conservation. Recycle as many materials as you can. Most cities and municipalities have recycling services or recycling centers where you can take your recyclable materials. When you recycle, you allow materials to be used more than once, which is good for our ecosystems because it means that fewer waste items are being put into landfills. Landfills are expanding and encroaching onto the natural habitats of

Over-development from sugar producers and urban sprawl have put tremendous stress on the entire ecosystem by draining the land and channeling the water.

They generate 32% of the world's net primary production They are distinguished from freshwater ecosystems by the presence of dissolved compounds , especially salts , in the water. Approximately 85% of the dissolved materials in seawater are sodium and chlorine . Seawater has an average salinity of 35 parts per thousand (ppt) of water. Actual salinity varies among different marine ecosystems.

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.

Researchers said warmer water affected the distribution and size of plankton - tiny organisms that form the basis of food chains in aquatic systems. The findings appear in the journal Global Change Biology. "Our study provides almost the first direct experimental evidence that - in the short-term - if a [freshwater] ecosystem warms up, it has profound implications for the size structure of plankton communities," said lead author Gabriel Yvon-Durocher from Queen Mary, University of London.

We specialize in technology development: SUSTAINABLE DEVELOPMENT: We design and develop EcoVillages (mixed-use environmentally sensitive housing/commercial communities) SOLAR ENERGY: We nurture technology development and identify market opportunities in solar energy (including passive solar design ) and energy conservation (such as the soon to be manufactured high efficiency TPTS gas-fired water heater); and ... TRANSPORTATION: We promote and nurture sustainable transportation alternatives ( electric and solar powered vehicles Ultra-Lite Rail Systems We employ the principles of Ecological Economics : Our planet is experiencing a crisis of unprecedented proportions: with increasing demands for resources of dwindling quality and increasing costs of extraction, we are consuming our "seed corn" and our wastes are piling up beyond our planet's capacity to absorb them. This is not sustainable in the long term. There are debates about how much time we have, but it is clear that humanity is challenging the limits of the natural order as never before. Virtually by definition, one of the solutions to achieving sustainability is the transition from an economy based on oil to one based on solar energy. Employing this solution, our programs and projects are based on two primary principles:

An Ecological System The word ecosystem is short for ecological systems. An ecosystem includes all of the living organisms in a specific area. These systems are the plants and animals interacting with their non-living environments (weather, Earth, Sun, soil, atmosphere). An ecosystem's development depends on the energy that moves in and out of that system. As far as the boundaries of an ecosystem, it depends upon how you use the term. You could have an entire ecosystem underneath a big rock. On the other hand, you could be talking about the overall ecosystem of the entire planet (biosphere). An ecosystem can be as small as a puddle or as large as the Pacific Ocean. That ecosystem includes every living and non-living thing in the area. It is several small communities interacting with each other. Let's look at a puddle example. You might start by looking at the temperature, depth, turbulence, sunlight, atmospheric pressure, weather patterns, wind, nutrients, etc. Those are just the non-living things in the ecosystem of a puddle. When you add on all the living interactions, you have a good idea how complex an ecosystem can be. Even a puddle is an amazing place. Biomes Scientists discuss some general ecosystem types. They call them biomes. A biome is a large area on the Earth's surface that is defined by the types of animals and plants living there. A biome can be partially defined by the local climate patterns. You may also have more than one type of biome within a larger climate zone. Here is a short list of possible biomes.
