“…An exception is the case of F. semicordata, where the main compound emitted by receptive figs, 4-methylanisole, represented alone more than 90% of floral scent ). This compound has never been reported in the scent of receptive figs of any of the other 40 fig species studied so far (Ware et al 1993;Gibernau et al 1998;Grison et al 1999, Grison-Pigé et al 2002bSong et al 2001;Proffit et al 2007Borges et al 2008;Proffit and Johnson 2009;C. Soler, unpublished data) and has been reported very rarely, always as a minor compound, in the floral scent of other plants (Knudsen et al 2006).…”

“…In several of these systems, the chemical message emitted by the plant to attract its pollinator has been characterized (Table 1). In fact, sympatric and co-flowering plant species involved in nursery pollination systems, and visited by different pollinators, produce qualitatively different chemical messages (Grison-Pigé et al 2002b;Okamoto et al 2007;Chen et al 2009;Proffit and Johnson 2009). Moreover, bioassays conducted on fig wasps and on Epicephala moths, pollinators of Glochidion trees, corroborate the role of scent as a prezygotic barrier between closely related plant species by showing that pollinators are able to discriminate their own host within the olfactory landscape (Raguso 2003) of compounds emitted by co-flowering plants (Grison-Pigé et al 2002a;Okamoto et al 2007;Chen et al 2009;).…”

Floral scents: their roles in nursery pollination mutualisms

Mutualisms are interspecies interactions in which each participant gains net benefits from interacting with its partner. In nursery pollination mutualisms, pollinators reproduce within the inflorescence they pollinate. In these systems, each partner depends directly on the other for its reproduction. Therefore, the signal responsible for partner encounter is crucial in these horizontally transmitted mutualisms, in which the association between specific partners must be renewed at each generation. As in many other interspecies interactions, chemical signals are suspected to be important in the functioning of these mutualisms. We synthesized and compared the published data available on the role of floral scents in the functioning of the 16 known independently evolved nursery pollination mutualisms. So far, attraction of pollinators to their specific hosts has been investigated in only seven of these systems, and the majority of the studies have been conducted on one of them, fig/fig wasp interactions. While such unevenness of the information limits the potential for meta-analysis, some patterns emerge from this review concerning the role of flower volatiles in maintaining the specificity of pollinator attraction, in signaling the appropriate phenological stage for pollinator visit, in attracting the pollinator toward the rewardless sex in dioecious plant species and in aiding the location and exploitation of resources by parasites and predators associated with these mutualisms. Finally, we highlight new perspectives on the evolution of signals in these diversified systems depending on the age and the degree of specificity of the interaction, and on the effect of phylogenetic inertia on the evolutionary dynamics of plant signals.

“…the systems involving dwarf palm/Derelomus weevils, and figs/fig wasps. 7,44 This simplicity could be due to selective pressure for plants to lower production costs of scents and/or to avoid attracting insects other than their specific pollinator ('cheaters' or parasites). Knowing whether or not L. mattanensis is specifically pollinated could allow an independent test of this hypothesis.…”

“…by figs at the stage when the wasps enter them to oviposit, and they are usually not attracted by the odours of other Ficus species [22][23][24]. The chemical message generally comprises several compounds and is differentiated among species [24,25]. The wasps are assumed to recognize a mixture of volatile organic compounds constituting the host species'-specific signature [23,[25][26][27].…”

Floral volatiles, pollinator sharing and diversification in the fig–wasp mutualism: insights from Ficus natalensis , and its two wasp pollinators (South Africa)

Combining biogeographic, ecological, morphological, molecular and chemical data, we document departure from strict specialization in the fig-pollinating wasp mutualism. We show that the pollinating wasps Elisabethiella stuckenbergi and Elisabethiella socotrensis form a species complex of five lineages in East and Southern Africa. Up to two morphologically distinct lineages were found to co-occur locally in the southern African region. Wasps belonging to a single lineage were frequently the main regional pollinators of several Ficus species. In South Africa, two sister lineages, E. stuckenbergi and E. socotrensis, pollinate Ficus natalensis but only E. stuckenbergi also regularly pollinates Ficus burkei. The two wasp species co-occur in individual trees of F. natalensis throughout KwaZulu-Natal. Floral volatile blends emitted by F. natalensis in KwaZulu-Natal were similar to those emitted by F. burkei and different from those produced by other African Ficus species. The fig odour similarity suggests evolutionary convergence to attract particular wasp species. The observed pattern may result from selection for pollinator sharing among Ficus species. Such a process, with one wasp species regionally pollinating several hosts, but several wasp species pollinating a given Ficus species across its geographical range could play an important role in the evolutionary dynamics of the Ficus-pollinating wasp association.
