U.S. Geological Survey Mercury Contamination of Aquatic Ecosystems Note: This file is also available in acrobat (.pdf) format: (file size 1.6 MB) Introduction Figure 1. States with at least one fish consumption advisory for mercury. Source: USEPA Fish Consumption Data Base. These continental to global scale occurrences of mercury contamination cannot be linked to individual emissions of mercury, but instead are due to widespread air pollution. When scientists measure mercury levels in air and surface water, however, the observed levels are extraordinarily low. Figure 2. The droplet of mercury shown in this slide is about 1 gram; the same amount that is in a standard mercury thermometer and the total amount that is deposited annually on a lake in northern Wisconsin with a surface area of 27 acres. In fact, scientists have to take extreme precautions to avoid direct contact with water samples or sample containers, to avert sample contamination Figure 3. Because there is actually very little mercury in most natural waters, scientists have to use extreme measures when sampling for mercury to avoid sample contamination from their hands and clothing. This entails the use of lint-free suits, plastic gloves, hoods, and stringently cleaned sampling equipment. Herein lies an apparent discrepancy: Why do fish from some remote areas have elevated mercury concentrations, when contamination levels in the environment are so low?

AMBIOS Home Page The objectives of this project are to determine the interrelationships between the physical properties of ecosystems and the ecology of organisms in the generation of biodiversity, to measure objectively the resultant diversity and to produce operational concepts of biodiversity which are of general applicability and importance. http://www.leeds.ac.uk/biology/research/europe/ambios.html

AMBIOS Home Page Integrating Environmental and Population Variation: A Model for Biodiversity Studies (AMBIOS) Areas of study: The relationships between breeding ecology, niche width and biogeographic range, and their bearing on the future dynamics of biodiversity at a time of accelerating environmental change and extinction will be studied. The development of operational concepts for assessing and describing the very basis of biodiversity will be established This will involve evaluating and comparing phenotypic and genotypic features as measures of the buffering capacity of the components of biodiversity with respect to changing environmental factors, and will be achieved by focusing on genetic heterogeneity levels and phenotypic responses in relation to the environment, and on thermal tolerance. The determination of the mechanisms involved in the transition from polymorphic, interbreeding populations to those of species status, and the elucidation of how such changes can be distinguished from phenotypic plasticity, will be addressed. Techniques for the identification of species and 'lower' taxonomic units will be developed, and new molecular methods tested in those species in which the levels of polymorphism are high.

89. Colloquium 1996 Modelling hydrodynamically dominated marine ecosystems. http://modb.oce.ulg.ac.be/Colloquium/1996.html

Modelling hydrodynamically dominated marine ecosystems General introduction International Scientific Committee Local Organizing Committee Sponsorship ... Proceedings - Instructions to authors. 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.

United States Trace Gas Network Welcome to the TRAGNET Home Page The atmospheric concentrations of greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are increasing substantially. These increases are expected to result in global warming and changes in precipitation patterns, and may directly affect terrestrial ecosystems. Our understanding of the contemporary fluxes of these gases between the land and atmosphere is incomplete. There are large regions of the earth for which we have very little information on trace gas fluxes. Furthermore, for no region do we fully understand how global change, including land-use change, will affect gas fluxes. The United States Trace Gas Network(TRAGNET) is meant to accomplish the following two goals: Document contemporary fluxes of CO2, CH4 and N2O between regionally important ecosystems and the atmosphere Determine the factors controlling these fluxes and improve our ability to predict future fluxes in response to ecosystem and climate change Part of this research is supported by the National Science Foundation.

Students will understand the following: Even a small area of land can offer wide biodiversity in plant life; that is, an ecosystem is composed of many different organisms. Each species of plant has its own name. Each ecosystem will contain evidence of diversity within each species. For this lesson, you will need: Access to an unmanaged part of the school grounds or of a local park Plastic bags for carrying leaf specimens Field guide to leaves Challenge your students to assess the biodiversity of their own community. Take them to a relatively unmanaged area of your property (or, for urban schools, to a local city park). Determine beforehand that the area does not contain any poisonous plants. Back in the classroom, make a list of the different leaves that were collected. (Naming the species is of secondary importance for assessing biodiversity, but it will be interesting to give your students the time and material to determine names of each plant.)

After decades of continuous change imposed by human activity, many of the world's natural ecosystems appear susceptible to sudden catastrophic change, an international consortium of scientists reported. Coral reefs and tropical forests are vulnerable, as are northern lakes and forests, the team has found. Marten Scheffer, an ecologist at the University of Wageningen in the Netherlands, said, "Models have predicted this, but only in recent years has enough evidence accumulated to tell us that resilience of many important ecosystems has become undermined to the point that even the slightest disturbance can make them collapse." Scheffer is the lead author of the study published Oct. 11 in the scientific journal

document.write(""); stats Back to the Virginians For Wilderness Homepage Forests of the Central Appalachians Project Inventories to Protect photos and text by Robert F. Mueller Introduction Fig. 1- Mesic Slope with Cow Parsnip and Trillium, Peaks of Otter. The Link Between Biological Inventories and Forest Protection Given that public agencies such as the U.S. Forest Service conduct biological inventories, how can additional ones be justified? We believe detailed knowledge of the forest is an imperative for its protection. However, given that the public agencies such as the US Forest Service conduct biological inventories, how can additional ones be justified? Unfortunately, to put it bluntly, inventories done by some public agencies, and particularly by the US Forest Service, cannot be trusted because they are frequently biased in such a way as to favor decisions already made. Also, to cut costs they are often conducted by unqualified personnel. It works as follows: Some public agencies, such as State Natural Heritage Programs, do produce trustworthy information. However when such information relates to national forests, or in some cases state lands, it may be suppressed by the US Forest Service or the state agency concerned. In some cases Natural Heritage employees have been threatened with withdrawal of support by the US Forest Service. Both Forest Service and Natural Heritage scientists have lost their positions when they refused to produce fraudulent inventories. Although many of the data we rely upon are obtained from our own field inventories, we also incorporate many from other sources. Unsuppressed natural Heritage Program inventories are highly reliable because they are conducted by academic and other experts who are beyond the reach of biased agencies. We make use of as many of these data as possible. However Natural Heritage Programs tend to concentrate on rare species and communities while we also require information on more widespread forest communities. Thus we have another reason for conducting our own inventories.

Sign in Search Community Gallery ... ezShop Ecosystems by Christopher Baker Home Travel Costa Rica ... CR Handbook : One Article In 1947, the biologist L.H. Holdridge introduced a system of classifying vegetation types or "zones" according to a matrix based on analyzing combinations of temperature, rainfall, and seasonality. Each zone has a distinctive natural vegetation and ecosystem. Costa Rica has 12 such zones, ranging from tidal mangrove swamps to subalpine with its stunted dwarf plants above the timberline atop the high mountains. Costa Rican Natural History, edited by Daniel Janzen, provides a description of the vegetation types associated with each life zone. You can also obtain a life zone map from the Tropical Science Center (Calle 1, Avenidas 4/6), a private nonprofit organization which operates the Monteverde Cloud Forest Reserve. Costa Rica's tropical situation, in combination with both a remarkable diversity of local relief and climates plus generous infusions since Miocene times of plants and animals from the adjoining continents, has resulted in the evolution of a stupendously rich biota. Some habitats, such as the mangrove swamps, are relatively noncomplex. Others, particularly the ecosystem of the tropical rainforests of the Caribbean lowlands and the Osa Peninsula (the only rainforest still extant on the Pacific side of Central America), are among the most complex on the planet. There is no barrier in Costa Rica to the entry of South American species of flora, and the lowland rainforests have strong affinities with the

Please call 703-820-2244 to schedule time More than one-half of the world's major rivers are being seriously depleted and polluted, degrading and poisoning the surrounding ecosystems, thus threatening the health and livelihood of people who depend upon them for irrigation, drinking and industrial water, says the World Commission on Water for the 21st Century (see attached map) "Overuse and misuse of land and water resources in river basins in both advanced industrial countries and developing countries constitute the primary cause for their decline," says Ismail Serageldin, Chairman of the World Commission on Water for the 21st Century , and World Bank Vice President for Special Programs. "The land and water crisis in river basins contributed to the total of 25 million environmental refugees last year, which for the first time exceeded the number of war-related refugees. By 2025, the number of environmental refugees could quadruple."
