Spatial organization

 Spatial patterns exhibited by ants (Temnothorax rugatulus) can be determined after each individual is painted with a distinguishing mark.
 The dominant paper wasp (Polistes flavus) remains in the center of the nest while subordinate wasps are often at the edge or off the nest.
 Bumble bees, Bombus impatiens individually marked with plastic number tags

Spatial organization can be observed when components of an abiotic or biological group are arranged non-randomly in space. Abiotic patterns, such as the ripple formations in sand dunes or the oscillating wave patterns of the Belousov-Zhabotinsky reaction emerge after thousands of particles interact millions of times. On the other hand, individuals in biological groups may be arranged non-randomly due to selfish behavior, dominance interactions, or cooperative behavior. W. D. Hamilton (1971) proposed that in a non-related "herd" of animals, spatial organization is likely a result of the selfish interests of individuals trying to acquire food or avoid predation. On the other hand, spatial arrangements have also been observed among highly related members of eusocial groups, suggesting that the arrangement of individuals may provide some advantage for the group.
