Dispersion pattern determined by neutral interactions is:
Random dispersion arises when individuals are positioned independently at the scale of observation, with neither strong attraction nor strong repulsion among neighbors. This can occur when resources are relatively homogeneous, propagules disperse without directional bias, and interactions among individuals are weak or neutral. Quadrat counts then approximate a Poisson distribution, whose variance equals its mean. Uniform dispersion instead reflects negative interactions such as territoriality, competition, or allelopathy, while clumped dispersion reflects attraction, limited dispersal, social
