Species Distribution - Random Distribution

Random Distribution

Random distribution, also known as unpredictable spacing, is the least common form of distribution in nature and occurs when the members of a given species are found in homogeneous environments in which the position of each individual is independent of the other individuals: they neither attract nor repel one another. Random distribution is rare in nature as biotic factors, such as the interactions with neighboring individuals, and abiotic factors, such as climate or soil conditions, generally cause organisms to be either clustered or spread apart. Random distribution usually occurs in habitats where environmental conditions and resources are consistent. This pattern of dispersion is characterized by the lack of any strong social interactions between species. For example; When dandelion seeds are dispersed by wind, random distribution will often occur as the seedlings land in random places determined by uncontrollable factors. Tropical fig trees exhibit random distribution as well because of wind pollination. In addition to tropical fig trees and dandelion seeds, oyster larvae can travel hundreds of kilometers powered by sea currents, which causes random distribution when the larvae land in random places. Although random is thought to be unpredictable, it is the only dispersion that has a mathematical equation to represent it. This is due to the individualistic characteristics of random dispersion based on the idea that every species has equal opportunity and access to resources.
