Spread of a species to a new location In many organisms, this happens at a particular stage in the life cycle, and is often crucial to the survival of the species Organisms may disperse as spores, seeds, eggs, larvae, or adults
The dispersal of a crowd involves splitting it up and making the people leave in different directions. The police ordered the dispersal of the crowds gathered round the building. the process of spreading things over a wide area or in different directions
(Dispersion) the movement of organisms or their spores or gametes throughout the ecological niche of that particular organism (Morris 1992)
The spreading of individuals away from each other, e g of offspring from their parents and from regions of high density to regions of lower density
The movement of an organism from the area where it was born and reared (its natal home range) to an area that may provide the necessary habitat conditions for establishing an adult home range For many species of animals dispersal is the period in which it will undertake its longest distance movement and during which it is most likely to encounter a variety of risks and inhospitable habitat conditions, including crossing highways (1)
