Overview

Establishment

Subject: Religion

In ecclesiastical usage, the recognition by the State of a particular Church as that of the State. In OT Judaism and in much of the ancient world, religious observance was part of the ...

beat up

beat up  

A foresters' phrase, meaning to replace dead trees with new ones, especially during the early years of the establishment or re-establishment of a plantation.
secondary speciation

secondary speciation  

The fusion through hybridization of two species that were formerly geographically isolated, followed by establishment of a new adaptive norm through natural selection.
replacement ecology

replacement ecology  

Where it is impossible to restore a site to its original condition, the establishment on it of a community entirely different from the original. Compare rehabilitation ecology; restoration ecology.
haplosis

haplosis  

The establishment of the gametic chromosome number by meiosis.
determination

determination  

The establishment of a single kind of histogenesis for a part of an embryo, which it will perform irrespective of its subsequent situations. Compare with differentiation.
regeneration niche

regeneration niche  

The specific niche that must exist in order for a plant to become re-established in an area it formerly occupied. A plant that can tolerate a wide range of environmental conditions when mature may ...
plasmid donation

plasmid donation  

The process by which a nonconjugative plasmid is transferred from a donor to a recipient cell via the effective contact function provided by a conjugative plasmid. In E. coli, for example, the ColE 1 ...
deletion mapping

deletion mapping  

1. the use of overlapping deletions to localize the position of an unknown gene on a chromosome or linkage map. 2. the establishment of gene order among several phage loci by a series of matings ...
germ plasm bank

germ plasm bank  

An establishment concerned primarily with the conservation of hereditary genetic material which may be lost through the process of genetic erosion. Germ plasm loss is a major concern in Asia, parts ...
pattern formation

pattern formation  

The establishment of basic body symmetries and repetition of parts during development. In animal embryos, for example, pattern formation defines the body axes, the number and polarity of body ...
rehabilitation ecology

rehabilitation ecology  

Where it is impossible to restore a site to its original condition, the establishment on it of a community which is similar to the original. Compare replacement ecology; restoration ecology; see also ...
riparian

riparian  

Relating to a river bank. Riparian vegetation dynamics are driven by allogenic hydrogeomorphological factors, with autogenic (plant-induced) influences affecting both plant dynamics and the river ...
secondary succession

secondary succession  

The re‐establishment of vegetation on land that has had a vegetation cover at some time in the past but which might have been destroyed by natural processes (including lightning fires, severe storms ...
Frederick Sanger

Frederick Sanger  

(1918–  )British biochemist who worked at Cambridge University and the Medical Research Council. He was awarded two Nobel Prizes for chemistry. The first was for his discovery of the amino-acid ...
territoriality

territoriality  

The establishment, demarcation, and defence of an area by animals, normally during mating ritual. Once territory has been established the animals can exist without disturbance and with sufficient ...
genetic resources

genetic resources  

The gene pool in natural and cultivated stocks of organisms that are available for human exploitation. It is desirable to maintain as diverse a range of organisms as possible, particularly of ...
gene bank

gene bank  

An establishment in which both somatic and hereditary genetic material (see germ plasm) are conserved. It stores, in a viable form, material from plants that are in danger of extinction in the wild ...
directional selection

directional selection  

Natural selection that favours the establishment of one particular advantageous mutation within a population, resulting in a change in phenotype in that direction. An example of directional selection ...
Nikolai Ivanovich Vavilov

Nikolai Ivanovich Vavilov  

(1887–1943)Soviet plant geneticist who made a vast collection of plant species from around the world and who proposed the theory that this diversity arose from several centres of origin located ...
succession

succession  

A progressive series of changes in the plant and animal life of a community from initial colonization to the establishment of a climax. The term applies to animals (especially to sessile animals in ...
