Extinction Extinction, in biology, the dying out or termination of a species. Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).

What is Extinction in Conditioning? - Definition & Explanation What was just described is called an extinction burst, which is the initial increase in the frequency and magnitude of the behavior prior to the gradual decrease and extinction of the behavior. This is especially likely to occur when the reinforcement is removed abruptly.

The Power in a Lot of Water Mass Extinction in the Fossil Record. Mass extinctions are apparent in the fossil record wherever some sort of organism virtually disappears from the geologic column above a certain layer. One of the most well-known mass extinctions is the disappearance of the dinosaurs and a number of other organisms at the K-T boundary.

- 1 In chemistry, biochemistry, molecular biology, or microbiology, the mass extinction coefficient and the molar extinction coefficient (also called molar absorptivity) are parameters defining how strongly a substance absorbs light at a given wavelength, per mass density or per molar concentration, respectively.xtinction coefficient refers to several different measures of the absorption of light in a medium:

extinction ex•tinc•tion. 1. the act of extinguishing. 2. the state of being extinguished or extinct. 3. the act or process of becoming extinct: the extinction of a species. 4. the reduction or loss of a conditioned response as a result of the absence or withdrawal of reinforcement.

Environmental impact of concrete In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water.

Language Death By Richard Nordquist. Definition. A linguistic term for the end or extinction of a language. Also called language extinction. Distinctions are commonly drawn between an endangered language (one with few or no children learning the language) and an extinct language (one in which the last native speaker has died). See Examples and Observations below.

What does Endangered mean What does Endangered mean. Endangered animals are basically those animals whose population is reducing at an alarming rate. This drastic reduction in numbers can be attributed to a number of things and it is therefore prudent to carefully learn about some of the possible causes of extinction. Below are just a couple of reasons that may result into wildlife extinction.

Definitions &Translations Extinction In biology and ecology, extinction is the end of an organism or of a group of organisms, normally a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point.

Extinction (psychology) Extinction burst[edit] While extinction, when implemented consistently over time, results in the eventual decrease of the undesired behavior, in the short-term the subject might exhibit what is called an extinction burst. An extinction burst will often occur when the extinction procedure has just begun.

Local extinction Local extinction or extirpation is the condition of a species that ceases to exist in the chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions may be followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this.
