Restoration Ecology
Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed or transformed. It is distinct from Conservation movement, conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures. Ecological restoration can help to reverse biodiversity loss, combat climate change, support the provision of ecosystem services and support local economies. The United Nations has named 2021–2030 the Decade on Ecosystem Restoration. Habitat restoration involves the deliberate rehabilitation of a specific area to reestablish a functional ecosystem. This may differ from historical baselines (the ecosystem's original condition at a particular point in time). To achieve successful habitat restoration, it is essential to understand the life cycles and interactions of species, as well as the essential elements such as food, water, nutrients, space, and s ...

Ecosystem Health And Sustainability
An ecosystem (or ecological system) is a system formed by organisms in interaction with their environment. The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain close to its equilibrium state, is termed its resistance. Its capacity to absorb disturbance and reorganiz ...

Wisconsin Public Radio
Wisconsin Public Radio (WPR) is a network of 38 public radio radio station, stations in the state of Wisconsin. WPR's network is divided into two distinct services, the ''WPR News Network'' and the ''WPR Music Network''. History Wisconsin Public Radio has origins that date to 1914. For history prior to the formation of Wisconsin Public Radio, see WHA (AM). The first real steps toward the building of what would become Wisconsin Public Radio began in 1947, with the sign-on of WHA-FM (now WERN) as a sister station to WHA. Between 1948 and 1965, seven more FM stations signed on as part of what was initially dubbed Wisconsin Educational Radio. The network became Wisconsin Public Radio in 1971, when it became a charter member of NPR, National Public Radio. Shortly afterward, the merger of the University of Wisconsin and Wisconsin State University systems into the present-day University of Wisconsin System greatly increased WPR's reach. WPR News WPR News is devoted mostly to NPR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abundance (ecology)
In ecology, local abundance is the relative representation of a species in a particular ecosystem. It is usually measured as the number of individuals found per sample. The ratio of abundance of one species to one or multiple other species living in an ecosystem is referred to as relative species abundances. Both indicators are relevant for computing biodiversity. A variety of sampling methods are used to measure abundance. For larger animals, these may include spotlight counts, track counts and roadkill counts, as well as presence at monitoring stations. In many plant communities the abundances of plant species are measured by plant cover, i.e. the relative area covered by different plant species in a small plot. Abundance is in simplest terms usually measured by identifying and counting every individual of every species in a given sector. It is common for the distribution of species to be skewed so that a few species take up the bulk of individuals collected. Relative spe ...

Nitrate
Nitrate is a polyatomic ion with the chemical formula . salt (chemistry), Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are solubility, soluble in water. An example of an insoluble nitrate is bismuth oxynitrate. Chemical structure The nitrate anion is the conjugate acid, conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. This charge results from a combination formal charge in which each of the three oxygens carries a − charge, whereas the nitrogen carries a +1 charge, all these adding up to formal charge of the polyatomic nitrate ion. This arrangement is commonly used as an example of Resonance (chemistry), resonance. Like the isoelectronic carbonate ion, the nitrate ion can be represented by three resonance structures: Che ...

Denitrification
Denitrification is a microbially facilitated process where nitrate (NO3−) is reduced and ultimately produces molecular nitrogen (N2) through a series of intermediate gaseous nitrogen oxide products. Facultative anaerobic bacteria perform denitrification as a type of respiration that reduces oxidized forms of nitrogen in response to the oxidation of an electron donor such as organic matter. The preferred nitrogen electron acceptors in order of most to least thermodynamically favorable include nitrate (NO3−), nitrite (NO2−), nitric oxide (NO), nitrous oxide (N2O) finally resulting in the production of dinitrogen (N2) completing the nitrogen cycle. Denitrifying microbes require a very low oxygen concentration of less than 10%, as well as organic C for energy. Since denitrification can remove NO3−, reducing its leaching to groundwater, it can be strategically used to treat sewage or animal residues of high nitrogen content. Denitrification can leak N2O, which is an ozone-d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
