Popis:	Analysis of spatial patterns using the classical nearest neighbor distribution is based on geometric points which have no size. For real ecological objects, size constraints the placement of neighbors. Therefore, the implied assumption of the classical approach that the total nearest neighbor area equals the sample area is no longer valid. In this study, the most probable nearest neighbor distribution for circles of any fixed diameter is derived. The results are compared with previous data and models describing the spatial pattern of ant-lion pits.
