Role of Spatial Aggregation in Forensic Entomology

1/1/2014 · The aggregation model of coexistence is based on the quantification of intraspecific and interspecific aggregation among patches. Ives (1988b) quantified intraspecific aggregation with the index J a, which is defined as proportional increase in the average number of conspecific competitors relative to a random distribution. J a is defined as: J a = {[Σ n i (n i − 1)/(NL)] − N}/ N, where n ...
