Modelling hydrodynamically dominated marine ecosystems General introduction International Scientific Committee Local Organizing Committee Sponsorship ... Special issue Journal of Marine Systems. General introduction Modelling ecosystems in a sustainable development perspective is a truly interdisciplinary challenge. Biogeochemical cycles cannot be considered independently of the hydrodynamic constraints exerted on them. Hydrodynamic processes the time scales of which correspond to the time scales of biological populations, capture these populations in their physical spatial structures (the so-called "ecohydrodynamic adjustment") and the frequency and persistence of the latter command the speed of the exchanges between the marine biosphere, the ocean reservoirs and the atmosphere. It is difficult to see how a simple model could be used to describe ecosystems and biogeochemical cycles. On the one hand, geochemical and ecological processes are strongly correlated with physical processes by the resonant interactions and subsequent scale matching of the ecohydrodynamic adjustment; in addition, they live on nutrient supplies which are partly regenerated in the water column - hence subject to the caprices of local hydrodynamics -, partly imported into the system through the boundaries (bottom-sediments, coasts, air-sea interface,...) with a spatial variability which, inevitably, is imprinted on the system's kinetics. On the other hand, the complexity and diversity of ecological and geochemical interactions webs leaves little hope for the development of realistic management models including too simpliste biology and geochemistry.

Siberian Branch of the RAS Institute of Cytology and Genetics Workshop on Information Technologies Application to Problems of Biodiversity and Dynamics of Ecosystems in North Eurasia (WITA'2001) CONCEPT of research into biodiversity and dynamics of ecosystems in northern Eurasia within the frames of international collaboration as formulated upon the First International Conference on Biodiversity and Dynamics of Ecosystems of Northern Eurasia (BDENE'2000) Novosibirsk Scientific Center, Siberian Branch of the Russian Academy of Sciences, August 21-26, 2000 PREAMBLE The United Nations Conference on Environment and Development (UNCED), held in Rio de Janeiro in June 1992, stated that there would be no alternative to the development of civilization complying with the maintenance of the balance between the negative consequences of socioeconomic progress on the one hand and preservation and reproduction of the biological diversity on the other. The concept of maintaining the ecological equilibrium and sustainable development formed the basis of environmental policies in the majority of developed countries. In 1995, Russia ratified the Convention on Biological Diversity (CBD). The Russia's obligations under CBD implied providing a necessary level of environmental preservation on its territory. It is evident that implementation of the concept of sustainable development necessarily requires the ecosystem-based approach to exploitation of the natural resources as well as application of optimal nature-preserving technologies. In turn, this necessitates a thorough understanding of the mechanisms underlying the function of natural ecosystems together with development of global and national strategies for environmental conservation and nature management.

Desert Ecosystems "It is easier to accept the message of the stars than the message of the salt desert. The stars speak of man's insignificance in the long eternity of time; the desert speaks of man's insignificance right now." Edwin Way Teale, 1956 The Mojave Desert Desert Tortoise Creosote Bush The Great Basin ... Coyotes What Makes a Desert? Many people believe that heat alone is enough to create a desert. Actually, it's lack of rainfall, often coupled with undeveloped soils that are unable to retain moisture, and high rates of evaporation due to low humidity. Technically, an area is arid, or a desert, if it receives less than 10 inches of precipitation per year. This precipitation is often erratic and unpredictable. Plant and animal life in desert areas are often poised on the edge of disaster due to these extreme conditions. Thus, while deserts have a reputation for being rugged and tough, they are actually very fragile and susceptible. U.S. Deserts There are four main U.S. desert regions, each loosely defined by its dominant plant communities. They are: *the Chihuahuan - a hot desert in S.E. New Mexico and W. Texas, but mostly south of the

127. Rec.gardens.ecosystems: Organic Gardening Based On Ecology rec.gardens.ecosystems is a moderated newsgroup. The group rec.gardens.ecosystems Homepage. About rec.gardens.ecosystems. rec.gardens 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.

Index to this page Lakes and Ponds Littoral zone Limnetic zone Profundal zone ... Rivers and Streams Freshwater Ecosystems Only 3% of the world's water is fresh. And 99% of this is either frozen in glaciers and pack ice or is buried in aquifers. The remainder is found in lakes, ponds, rivers, and streams. Lakes and Ponds Deep lakes contain three distinct zones, each with its characteristic communities of organisms. Littoral zone The zone close to shore. Here light reaches all the way to the bottom. The producers are plants rooted to the bottom and algae attached to the plants and to any other solid substrate. The consumers include tiny crustaceans flatworms insect larvae snails frogs, fish, and turtles. Limnetic zone This is the layer of open water where photosynthesis can occur. As one descends deeper in the limnetic zone, the amount of light decreases until a depth is reached where the rate of photosynthesis becomes equal to the rate of respiration. At this level, net primary production no longer occurs. The limnetic zone is shallower is turbid water than in clear and is a more prominent feature of lakes than of ponds.

136. California's Coastal Wetlands Information about the characteristics and functions of coastal wetland ecosystems. http://ceres.ca.gov/ceres/calweb/coastal/wetlands.html

The following materials are exerpts from the California Coastal Commission's California Coastal Resource Guide , which can be ordered from University of California Press by calling 1-800-822-6657. Wetlands are unique among biologic communities in that they are characterized by both aquatic and terrestrial features. Plants and animals that inhabit wetlands have successfully evolved morphological and physiological adaptations to the presence of high levels of salt and periodic inundation and desiccation, as well as to low concentrations of dissolved oxygen in the water- logged soils and exposure to alternating salt and fresh water. Many wetland inhabitants, including salt marsh plants and some water birds are able to excrete the excessive amounts of salt that are absorbed or ingested. Ecologists have estimated that a healthy salt marsh produces five to ten times as much oxygen and corresponding carbohydrate biomass per acre as a wheat field. Marsh plants capture the energy of sunlight and form the basis the highly productive wetland food web. A key part of the wetlands success is the breakdown of plant matter into detritus, which is then consumed by filter feeders, deposit feeders, and other omnivores and scavengers. This assemblage of producers and consumers creates a large food web, with fish, birds, and humans as ultimate links. Decomposers, such as bacteria and fungi, also break down plant and animal matter and recycle the nutrients. Excrement from birds, fish, and invertebrates further enhances marsh soils and waters with nitrogen rich compounds, which are taken up by algae and vascular plants. These materials are transported and mixed by streamflows, tidal circulation, and even the activities of burrowing clams and shrimp. As a result, the mudflats become rich in inorganic nutrients and organic foods. This "mixing bowl" helps to support the many links of the marsh's food chains. Salt marsh food webs are among the most complex in nature.
