The number of pollinium insertions per visit versus inflorescence size (A) and stem size (B). Inflorescence size is the number of open flowers on the visited inflorescence, and stem size is the total number of open flowers on the visited stem. We estimated the coefficients (β) using a zero-inflated Poisson-generalized log-linear model, and we calculated χ2s and Ps using likelihood ratio tests to determine if βs were significantly different from zero.
