allo-, all-

Related to a life form occurring in two or more communities within a given geographical region: An allochoric species inhabits two or more closely related communities in the same region,such as forest and a grassland,

Pertaining to a color variation or having the ability to change color: There are some animals that are allochroic and among them are the mimic octopus, the chameleon, and the Pacific Tree Frog.

An alteration or modification of color: Allochroism or change in color is used by some animals as a means of warning, including warding off a danger.

The formation of other coloring agents from a dye that is unstable in solution: Jane read about allochromacy as being a way of to achieve a coloring agent from a dye which was variable in a mixture or colloid.

A change in the color of the hair and/or skin: Some reasons for allochromasia can be produced by variation in pigmentation, too much sunlight, or by a disorder.

In physics, the radiation emitted from a substance at a particular wavelength: Aallochromy results from the absorption of incident radiation of a different wavelength which occurs in fluorescence or the Raman effect.

1. Relating to the condition of not being contemporary, or existing at different times: There have been allochronic populations of species living, growing, or reproducing during different seasons of a year.
2. Pertaining to different segments of geologic time: Susie wanted to know what plants occurred in the allochronic periods of the Earth's history.

A form of organic evolution starting from a life-giving reproduction that happens due to a change in time of breeding which lessens or stops gene flow between two groups of a species: Allochronic speciation is the process of developing different biological groups as a result of members of the population that have different breeding seasons or patterns, or differing in the use of time during the day or night, rather than through geographic separation.

A geological formation not created in the region where it was found: Allochthon takes place when a geological structure is moved to its present location by tectonic forces.

An allochthon is a mass of rock that has been transported a great distance from its original place of deposition, usually by tectonic forces, such as overthrusting or gravity sliding.

Am allochthon can be a rock mass formed somewhere other than its present location and was transported by fault movements, large-scale gravity sliding, or similar processes.

Referring to something not native to a particular habitat: Allochthonous rocks or deposits have emigrated or been imported from another environment.

Allochthonous features of a landscape or elements of its geologic structure are those that have been moved to their current position by tectonic forces.

In geology, allochthonous substances in a present site are at a distance from their place of origin.

A type of coal formed from accumulated plant material that was transported from its original place of growth and deposited elsewhere: Judy's teacher told his class about allochthonous coal that had been formed from plant substances that accrued from a place far from where the coal was formed.

A stream that flows in a channel it did not itself form: Mr. Smart showed his class a photo of a river, or allochthonous stream, rushing along in a man-made or artificial duct.

A biomass not native to a particular habitat; allochthonous biomass: Susan read that am allochthony related to organic matter , like that of vegetation, that had its origin in some other environment.

A movement on the side of the body opposite the one the patient was asked to move: After many times, Mrs. Thompson always lifted her right hand when told to, but instead she always lifted her left hand, and Dr. Hathaway diagnosed her as having a condition of allocinesia.

Passive or reflex movement other than controlled motion: The elderly Mr. Brown suffered from involuntary movements , which he did not intend, and his doctor told him that he had a disorder called allocinesis.
