Article Draft

What's missing from the article: A section on mechanisms of seed dispersal. Also, a section that talks about the evolutionary history of seed dispersal.

Notes for improvement -more/better images of seed dispersal -add to allochory section -clarify the definition -do section on spatial dispersal of seeds -dispersal is passive -it is a unidirectional movement away from place of birth -seeds carried by vectors, animals, wind and water

Spatial Dispersal of Seeds Long distance seed dispersal, otherwise known as LDD, occurs in response to a plant's surrounding environment. This type of spatial dispersal is defined by a proportional and actual distance. The proportional distance is used to describe plants with extraordinary dispersal distances. This LDD method measures the percentage of seeds (1% out of total number of seeds produced) that travel the farthest distance out of a 99% probability distribution.[1][2] The actual or absolute method identifies a literal distance of 1 km as the threshold distance for seed dispersal, threshold meaning the minimum distance a plant can disperse its seeds and qualify as a user of LDD.[1][2]
