Dispersal is a universal biological need, and it is to be expected that most higher plants have solved the problem in one way or another through adaptations involving their fruit or seed.
dispersal -- The scattering of organisms of a species, often following a major reproductive event. Spores and larvae are commonly dispersed into the environment.
Dispersal of Malaria and Chloroquine Resistance
Comparison of the distribution of the malaria parasite and chloroquine resistance around the world.
dispersal of the species to new locations (aided in angiosperms by the fruit)
survival of the species during unfavorable climatic periods (e.g., winter). "Annual" plants (e.g., beans, cereal grains, many weeds) can survive freezing only as seeds.
dispersal A more or less permanent movement of an individual from an area, such as movement of a juvenile away from its place of birth.
Dispersal (sensu ecology): the transport of propagules away from the parent. Diversity: a) the total number of species present;
b) some index which incorporates both the number of species and the relative abundance of each.
The splitting of lineages (1 above) in the mode of allopatric speciation (2 above) followed by ecological dispersal and succession (5 above) would result in geologically abrupt appearance of the daughter species everywhere except the limited ...
Lichens most frequently reproduce asexually, either by vegetative reproduction or through the dispersal of diaspores containing algal and fungal cells.
drift. The aerial dispersal of a substance such as a pesticide beyond the intended application area.
DTPA. A chemical solution used to determine available zinc in the soil: [[(carboxymethyl) imino] bis (ethyleneitrilo)l tetra-acetic acid.

The group is defined by their jointed stems, with many leaves being produced at a node, production of isospores in cones borne at the tips of stems, and spores bearing elaters (devices to aid in spore dispersal).
Inbreeding is mating between relatives to a greater extent than by chance; inbreeding can occur if dispersal is so low that mates are likely to be related and does not change allele frequencies, ...
Biogeography studies the spatial distribution of organisms on the Earth,[64] focusing on topics like plate tectonics, climate change, dispersal and migration, and cladistics.
