Realized tolerance to nectar robbing did not vary in Ipomopsis aggregata, as indicated through through female reproduction, estimated as (A) pollen receipt, (B) proportion of fruit set, (C) seed set per fruit and (D) total seeds per plant. Each symbol is a group mean (±s.e.) at either a low or high nectar-robbing level (<10 and >80 % of flowers robbed, respectively). There was no statistically significant interaction between group and robbing treatment for components of female reproduction.
