Larger Fig Wasps Are More Careful About Which Figs to Enter – With Good Reason
Floral longevity reflects a balance between gains in pollinator visitation and the costs of flower maintenance. Because rewards to pollinators change over time, older flowers may be less attractive, reducing the value of extended longevity. Un-pollinated figs, the inflorescences of Ficus species, can remain receptive for long periods, but figs that are older when entered by their host-specific ...
متن کاملFigs and fig wasps
The current project builds on previous grants under the Darwin Initiative that focused on Nepal's flora, a key one of which dealt with plant information and technology transfer, run by the Natural History Museum in London. But the current project is much more ambitious. Although only funded for three years at present, the team hopes funds will be made available for the estimated 15 years it wil...
متن کاملMutualists with attitude: coevolving fig wasps and figs
The intimate mutualism between fig wasps and figs has long captivated biologists, and new phylogenies are now uncovering its evolutionary history. Fig-pollinating wasps evolved just once, but fig parasitism has evolved repeatedly and convergently. Figs and their pollinators appear to have co-speciated considerably, but not invariably, because the famous one-to-one rule of specificity is often b...
متن کاملBetween-species facilitation by male fig wasps in shared figs
1. Facilitation, where one species helps another without cost or benefit to itself, is recorded from diverse plant-insect interactions, including pollination and herbivory. We investigated the significance of facilitation resulting from the behaviour of pollinator fig wasps inside figs shared with other species. Fig wasp females emerge from natal figs via exit holes dug by pollinator and some o...
متن کاملOnly pollinator fig wasps have males that collaborate to release their females from figs of an Asian fig tree.
Male insects rarely collaborate with each other, but pollinator fig wasps (Hymenoptera: Agaonidae) are said to be an exception. Immature fig wasps feed on galled ovules located inside figs, the inflorescences of Ficus species (Moraceae). After mating, adult pollinator males chew communal exit-holes that allow mated females (which are often also their siblings) to escape. Figs also support non-p...
