Description

Ant species incidence frequencies for samples from five elevations in northeastern Costa Rica (Longino and Colwell 2011). The number of sampling units (1m x 1m forest floor plot) for the 5 sites are respectively 599, 230, 150, 200 and 200. The number of observed species for the 5 sites are respectively 227, 241, 122, 56 and 14.
