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 reproductive 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.
