Ecotopía: A utopia conceived under ideal environmental budgets or. It is also the title of a famous and successful science fiction novel that tells the story of a self-managed and independent community in North America in the immediate future.

ecotype. botanically, populations of a species showing adaptive features associated with a particular environment. Although different ecotypes of a species differ from each other, crossbreeding are possible. The ecotipismo is a form of variation associated with the medium and does not necessarily imply separation of populations in geographical areas isolated from each other. According to some ecologists the term is somewhat ambiguous.

Ecotono. In an ecosystem, transition zone between two communities or biocenosis, where environmental conditions allow the coexistence of species typical of both.

edaphology. Science that studies the soil in composition, structure, classification, training and agricultural potential.

Environmental education: Action and effect of educating and informing authorities on all matters relating to the definition, preservation and restoration of the different elements of the environment.

Greenhouse effect. Warming produced by altering the thermal balance due to increased concentration of gases that do not transmit longwave (greenhouse gases such as carbon dioxide, CO2 and methane, CH4). The thermal balance of the atmosphere depends on the balance between inputs and outputs of radiant energy. Most of the air heating due to solar energy materials absorb the planet's surface and then refer to longer wavelength, so the increase in the concentration of greenhouse gases alter the thermal balance by reducing power outputs of the atmosphere.

Energy. It is the ability to produce work. In a closed system there is no gain or loss energy, only changes. The material is considered a condensed form of energy. The mass-energy equivalence follows the equation einsteniana (E=mc2, where E is the energy, m is the mass and c the speed of light in vacuum).

Alternative energies. Energies obtained from sources such as coal to classic, oil and natural gas. They are alternative energy solar, wind, geothermal, tidal and biomass, what, also, They are renewable energy. If the concept of traditional or conventional energy is reduced to fossil fuels, nuclear energy and hydropower have considered alternative energy.

Renewable energy. Energy from renewable sources by part of natural cycles and in opposition to those coming reservation. Renewable energy are solar, wind, of the water, tidal and biomass.

Enterovirus. pathogenic virus found in the digestive and respiratory and nervous system.

Epicenter. Point of the Earth's surface located vertically above the focus or hypocenter of an earthquake.

Roentgen equivalent. Roentgen unit dose equivalent. It is the radiation dose that produces the same biological effects 1 Roentgen ray X. Equals 0.01 julio/kg. Short rem.

Erosion. Destruction of the earth's surface materials (rocks and soil) physically separating particles of any size due to the action of external agents (wind, Water, ice). The intensity of erosion depends on the energy of the erosive agent, the nature of the materials (litología), the degree of weathering, the slope, and in the case of soil, the degree of vegetative cover and rooting, so that human actions on the vegetation and soil erosion may favor.

Richter scale. Scale for measuring the magnitude of earthquakes, proposal 1935 Charles Richter and Beno by Gutemberg. On this scale the magnitude is defined as the logarithm of the maximum amplitude, in microns, un recorded by the seismograph estandard 100 km. the epicenter. For its logarithmic nature, for every increase of quantity in a unit, the size of the earthquake increases tenfold, i.e., an earthquake of magnitude 5 It is a hundred thousand times greater than a magnitude 1. Although the ESCA Richter has no upper limit, Undetected earthquakes of magnitude greater than 9.

scale topographic. cartography, numerical relationship between distances on the map and the actual distances. They are often used scales, inter 1/1,000,000, 1/200,000 and 1/50,000.

Esciófilo. Species requiring shadow.

runoff. inland water surface movement not channeled in favor of the slope. The form of water movement can be laminar, turbulent or arroyada.

fishing effort. Measure of the intensity with which operates a fleet of fishery resources. Depends on the installed capacity of vessels and the number of fishing days. The value of the total catch of a fleet divided by the number of horsepower of the total installed capacity or the number of fishing days, is the catch per unit effort, a unit used in the study of fisheries.

game species. Animal species whose hunting is permitted, although subject to regulatory standards, whether general, temporary or specific for a particular species.

protected species. Species subject to legal measures that prevent their capture, sale, hunting, possession or killing.

Species. Group of organisms formed by populations of individuals occupying a habitat and interbreed. This species concept, which is the biological (bioespecie), It is useless in those organisms whose reproduction is totally asexual, in which case depends solely on morphological criteria (morfoespecie), that can be completed with ecological criteria. The taxon species is called with two Latin terms, The genus name followed by the specific name.

foreign species. Species of plants or animals from a place other than that in which they live, and have therefore been introduced.

native species. Species of plants or animals originating in living room.

Endemic species. An endemic species is one that exists only in a particular geographical area, variable length, but generally restricted to the size of the areas of the species with which compares.

Foam. dispersed system wherein the dispersing phase is liquid, usually water, and the dispersed phase is a gas.

In nature it is found mostly in oxide form (casiterita). It has industrial applications in alloys, welding and packaging (tinfoil). symbol Sn.

steppes. flat areas or low relief with little vegetation cover, mainly herbaceous and woody vegetation or nearly absent, with an extreme climate characterized by a significant summer drought. There are cold steppes, continental, and warm steppes representing the transition between vegetation and Mediterranean climate and desert. Steppe areas have often saline soils (halophytic steppes).

Stereo. Unit volume which is used in materials such as wood, firewood, branches and brozas, leaving holes together. Its value is 1 cubic meter.

fecal streptococci. Bacteria group streptococci they are living in the large intestine whose presence in water indicates contamination by pouring sewage.

Estuary. Flared mouth of a river in the sea, where the mixture of fresh and marine waters is carried out and which is subject to tidal action.

Environment Effect investigation: It is the set of information that must be submitted to the competent environmental authority and the environmental license request.

Eucalyptus. Tree of the genus Eucalyptus (family Mirtáceas). They are native to Australia and are spreading throughout the world to be exploited by the paper industry (cellulose), given its growth rate and their ability to live in poor soils. Many areas in many countries have often been planted with eucalyptus terracing mountain and eliminating the natural vegetation, environmental impact to which must be added the intense action of this tree on the ground by the secretion of substances by the roots and the difficult decomposition of fallen leaves.

eutrophication. natural process in aquatic ecosystems, especially in lakes, characterized by an increase in the concentration of nutrients such as nitrates and phosphates, with consequent changes in the composition of the community of living things. The eutrophic waters in contrast to the more productive oligotrophic. However, beyond certain limits, the process is of negative to large amounts of organic matter whose characteristics appear microbial decomposition causes a decrease in oxygen levels. Eutrophication occurs in many water bodies as a result of agricultural runoff, urban and industrial.

AET. In a particular soil surface water losses by evaporation are from to) direct evaporation from the soil into the atmosphere and b) water loss through plant transpiration, the previously they absorbed from the soil by its roots. Useful add two losses thus obtained evapotranspiration. It distinguishes potential evapotranspiration, which it is what would correspond to a particular region by climate, if precipitation were not a limiting factor, and actual evapotranspiration, which it is what actually occurs. So in an arid area of ​​high temperatures and scarce rainfall, potential evapotranspiration can be raised and the actual small.

Extinction: Process it is affecting many animal and plant species, threatening their survival, mainly because of the action of man, which has been changing and reducing their natural environment.
