“…Then, to which type of reproductive success do olfactory cues contribute? Several studies have examined the relative contribution of diurnal and nocturnal pollinators to female reproductive success (Cruden 1973;Haber and Frankie 1982;Jennersten 1988;Guitian et al 1993;Fleming and Holland 1998;Groman and Pellmyr 1999;Arizaga et al 2000;Slauson 2000) and to male and female reproductive successes (Bertin and Willson 1980;Morse and Fritz 1983;Jennersten and Morse 1991;Young 2002). In the latter studies, two patterns have been reported, in addition to the above-stated pattern reported by : diurnal pollinators contribute more to both male and female reproductive successes in Asclepias species (Bertin and Willson 1980;Morse and Fritz 1983;Jennersten and Morse 1991), whereas nocturnal pollinators contribute more to both successes in Silene alba (Young 2002).…”

“…While some plants flower only during a part of the day and rely on either diurnal or nocturnal pollinators, others are visited by both diurnal and nocturnal pollinators (Cruden 1973;Bertin and Willson 1980;Haber and Frankie 1982;Morse and Fritz 1983;Jennersten 1988;Guitian et al 1993;Groman and Pellmyr 1999;Arizaga et al 2000;Slauson 2000;Young 2002;Jürgens et al 2003). For example, Yahara (1998, 1999) showed that both diurnal and nocturnal pollinators are important for reproductive success in Lonicera japonica, which opens at dusk and withers 2 days from anthesis.…”

Day–night fluctuations in floral scent and their effects on reproductive success in Lilium auratum

We examined the contribution of diurnal and nocturnal pollination to male and female reproductive success in Lilium auratum. Plants were bagged for either 12 h during the day or at night to allow either only nocturnal or only diurnal visitors to forage throughout the flowering period. We found that there was no significant difference in the seed:ovule ratio among diurnally pollinated, nocturnally pollinated, or control flowers. However, in terms of male reproductive success, it was more advantageous for the plants to be pollinated both diurnally and nocturnally: the numbers of pollen grains remaining in diurnally pollinated or nocturnally pollinated flowers were significantly greater than those in control flowers. The total amount of floral volatiles of L. auratum was significantly higher at night than during the day. The constituents of floral scent of all time series examined were mostly monoterpenoids, many of which serve as attractants for nocturnal hawkmoths. Such nocturnally biased floral scent emission of L. auratum might achieve male reproductive success by attracting nocturnal visitors, which may suggest that the relative contribution of floral scent in this species is biased towards male reproductive success.

“…In some cases, the effectiveness of nocturnal pollinators is greater even when diurnal visits are more abundant (Groman and Pellmyr, 1999). However, moth visitation was observed only in S. integrifolius and at a very low rate (only two visits in 30 h of observation during six consecutive nights) compared with bee visitation.…”

Concerted changes in flower morphology and pollinators provide strong evidence on adaptive evolution. Schizanthus (Solanaceae) has zygomorphic flowers and consists of 12 species of annual or biennial herbs that are distributed mainly in Chile and characterized by bee-, hummingbird-, and moth-pollination syndromes. To infer whether flowers diversified in relation to pollinator shifts, we traced the evolutionary trajectory of flower traits and visitors onto a phylogeny based on sequence data from ITS, waxy, and trnF/ndhJ DNA. Maximum-likelihood ancestral reconstruction of floral traits suggests that ancestral Schizanthus had a bee-pollination syndrome. The hummingbird syndrome evolved in S. grahamii, a high elevation species in the Andes. The moth syndrome evolved in the ancestor of three species that inhabit the Atacama Desert. Results of mapping flower visitors onto the phylogeny show that the shift from bee to hummingbird pollination concurred with a shift in pollinators as predicted by the syndromes. However, the same pattern was not found for the moth syndrome. Visits by moths were observed only in one of the three moth-syndrome species, and at a very low rate. This mismatch suggests either anachronic floral characters or maintenance of rare, imperceptible moth pollination backed up by capacity for autonomous selfing. Overall, results suggest that diversification of flower traits in Schizanthus has occurred in relation to pollinator shifts.

From dusk till dawn: nocturnal and diurnal pollination in the epiphyteTillandsia heterophylla(Bromeliaceae)

et al. 2015

In order to compare the effectiveness of diurnal and nocturnal pollinators, we studied the reproductive biology and pollinators of Tillandsia heterophylla E. Morren, an epiphytic tank bromeliad endemic to southeastern Mexico. Since anthesis in T. heterophylla is predominantly nocturnal but lasts until the following day, we hypothesised that this bromeliad would receive visits from both diurnal and nocturnal visitors, but that nocturnal visitors would be the most effective pollinators, since they arrive first to the receptive flower, and that bats would be the most frequent nocturnal visitors, given the characteristics of the nectar. Flowering of T. heterophylla began in May and lasted until July. The species is fully self-compatible, with an anthesis that lasts for ca. 15-16 h. Mean volume of nectar produced per flower was 82.21 μl, with a mean sugar concentration of 6.33%. The highest volume and concentration of nectar were found at 20:00 h, with a subsequent decline in both to almost zero over the following 12-h period. T. heterophylla has a generalist pollination system, since at least four different morphospecies of visitors pollinate its flowers: bats, moths, hummingbirds and bees. Most of the pollinating visits corresponded to bats and took place in the early evening, when stigma receptivity had already begun; making bats the probable pollinator on most occasions. However, diurnal pollinators may be important as a 'fail-safe' system by which to guarantee the pollination of T. heterophylla.
