“…Compared to the six hand cross-pollinated flowers' fruit production (100%), natural fruit production in the external control group at Site 2 was low (58%), but higher than the one reported by Dar et al (2006) for their naturally pollinated control group (45.4%) and Badano and Schlumpberger (2001) at their Site 1 (50%).…”

“…The very low fruit production rates in both excluded groups at Site 1 (17% in the nocturnally excluded and 24% in the diurnally excluded group) might on the one hand be explained by the even lower number of synchronically open flowers. On the other hand, Dar et al (2006) reported even lower fruit set percentages both in nocturnal (8.33%) and diurnal (2.8%) pollination treatments that were obviously not caused by a low number of synchronically open flowers, as the number of plants at their study site was much higher. Thus the very low fruit set in the nocturnal and diurnal pollination treatments at Site1 appears mainly as a result of pollen limitation caused by the exclusion of one (respectively two) of the pollinator guilds.…”

“…Yet, many columnar cacti with nocturnal flowers extend their anthesis into the following morning or even afternoon, and Polaskia chichipe has been reported to extend its diurnal flowers being open into the night (OteroArnaiz et al, 2003, cited in Dar et al, 2006. Extending floral anthesis to the following day or night adds the possibility of visits by new guilds of pollinators at little extra cost to the plant, thus adding to seed production at times when the original pollinators are scarce and/or unpredictable (Dar et al, 2006;Sahley, 1996). Such mixed pollination syndromes are considered to be a common reproductive strategy in extratropical columnar cacti with diurnal and nocturnal flowers (Nassar et al, 1997).…”

“…Hawkmoths are highly migratory in search of food and during their pre-reproductive phases (Gibson, 2001;Southwood, 1962), generally considered to be locally and temporally scarce (Dar et al, 2006;Raguso et al, 2003;Schlumpberger and Badano, 2005;Ureta and Donoso, 1956), and, together with low flower numbers [in small populations] this might lead to low pollination efficiency rates (Raguso et al, 2003). The presence and abundance of hawkmoths in a certain area may be influenced by betweenyear variations in temperatures and precipitation (Sahley, 1996;Schlumpberger and Badano, 2005).…”

“…Both specialized and mixed pollination syndromes have been described for columnar cacti in the Americas. Specializations for bat- (Nassar et al, 1997;Valiente-Banuet et al, 1996), hummingbird- (Valiente-Banuet et al, 1996), hawkmoth- (Fleming and Holland, 1998;Silva and Sazima, 1995;Valiente-Banuet et al, 1996) or bee pollination (Valiente-Banuet et al, 2002) have been reported, but also mixed pollination by bats, diurnal insects and hummingbirds (Sahley, 1996;Valiente-Banuet et al, 2002), and by bats and hummingbirds (Dar et al, 2006). Finally, evidence for a mixed pollination by hawkmoths, hummingbirds and diurnal insects has been documented for E. atacamensis ssp.…”

Pollination is a key ecological function of most terrestrial ecosystems. Decades of research on single-trophic-level communities, particularly plant communities, have helped to build the foundation of diversity-function theory. Yet as it stands, this theory appears to be less useful for intertrophic-level functions such as pollination, as evidenced by empirical findings that are often inconsistent with theoretical expectations. In this review, we evaluate how canonical diversity-function theory has been applied to pollination function, focusing on empirical studies of the mechanisms that drive pollinator diversity-function relationships. We first identified key features of pollination function that have hampered reconciliation with current theory. We then examined terminology for mechanisms used to discuss the findings from pollinator diversity-function studies that are sometimes inconsistent with established ecological concepts. We propose a revised diversity-function framework and describe two noncanonical diversity-function mechanisms that are particularly applicable to pollination. The first, "interactive functional complementarity," was identified previously but remains overlooked. The second, a new diversity-function mechanism, "functional enhancement," occurs when pollinator diversity increases within-niche activity. Finally, we discuss experimental approaches necessary to detect diversity-function effects in pollination.
