Figure 2. California sea lion reproductive rate versus frequency of human exposure.

Reproductive rate and human exposure frequency during June, July and August in 3 years: (A) average reproductive rate; (B) maximum reproductive rate. Symbols depict observed data; the curve shows model predictions that are back-transformed to depict the regression of reproductive rate (pups/females) on frequency of human exposure (days with observed human presence/number of observation days in scanning period). Each curve represents a mean of the curves for the individual islands.
