DispersalAtomizedClass

The permanent spreading of individuals away from each other not including return. Dispersal determines the range over which genetic mixing occurs, and thus, the degree of homogeneity and inbreeding in a population.

Purpose

Context in which dispersed information is expressed: e.g. time or geographical scale.

Class: MeasurementOrFactClass

Type

Means or vector of dispersal.

A controlled vocabulary is recommended.

e.g. Zoochory, Anemochory, Hydrochory, Barochory, Autochory

Class: [NormalString] (https://github.com/tdwg/PlinianCore/wiki/NormalString)

StructureDispersed

Mechanism or structure which seeds are dispersed. A controlled vocabulary is recommended.

e.g. Seed, Fruit, Vegetative structure, Spores, Gametes, Eggs, Offspring and Individuals

Class: [NormalString] (https://github.com/tdwg/PlinianCore/wiki/NormalString)

Distance

Dispersal distance.

e.g. 450 m

Class: MeasurementOrFactClass
