Box plots of pollen transfer experiments. The height of the box is equal to the interquartile distance (IQD), which is the difference between the third and first quartile of the data. The whiskers extend to the extreme values of the data or to 1.5 IQD from the centre (whichever is less). The solid line inside the box indicates the median. Mean exsertion lengths are given in parentheses. (a) The experiment with B. sodiroana and B. ceratocarpa (N=8 bats). For each female flower, there was no statistical difference in the amount of conspecific vs. heterospecific pollen grains received (B. sodiroana: t=1.02, d.f.=5, p=0.35; B. ceratocarpa: t=−0.01, d.f.=5, p=0.99). (b) The experiment with B. sodiroana and B. cylindrocarpa (N=8 bats). Each female received significantly more conspecific than heterospecific pollen (B. sodiroana: t=5.19, d.f.=7, p=0.0012; B. cylindrocarpa: t=−4.23, d.f.=7, p=0.0039). (c) The experiment with B. sodiroana and B. borjensis (N=6 bats). Each female received significantly more conspecific than heterospecific pollen (B. sodiroana: t=3.45, d.f.=5, p=0.0183, B. cylindrocarpa: t=−6.45, d.f.=5, p=0.0013). (d) The experiment with B. sodiroana and B. succulenta (N=6 bats). Each female received significantly more conspecific than heterospecific pollen (B. sodiroana: t=16.93, d.f.=7, p≤0.0001; B. succulenta: t=−5.67, d.f.=7, p=0.0008).
