Our P. royenii population flowered throughout the year, but flower production was highly irregular fluctuating about 30-fold throughout the year. Moreover, fruit production was asynchronous with rainfall or flower production, corresponding three times and lagging after a fourth flowering peak. We did not detect any relationship between either flowering or fruiting phenology, and either rainfall or repro- ductive activity of the bats, which for M. redmani is from December through February. This is consistent with a loose relationship with the bats whose increased energy demands during reproductive periods fail to increase visitation and increase in fruit production.
