Table 1 in Biology and ecology of a deep cave nesting spider wasp, Ageniella evansi Townes, (Hymenoptera: Pompilidae), in Arizona

Table 1. Pearson correlation coefficients (r) were determined by comparing winter, summer, and annual precipitation data with the annual female wasp population at Arkenstone Cave. Current year precipitation values were aligned with the corresponding wasp population. Each year shift moves the alignment of the wasp population data earlier to test for correlation with precipitation effects on the population. A 34-year data set and a 9-year data subset are presented.
