Host sanctions and pollinator cheating in the fig tree-fig wasp mutualism.
Theory predicts that mutualisms should be vulnerable to invasion by cheaters, yet mutualistic interactions are both ancient and diverse. What prevents one partner from reaping the benefits of the interaction without paying the costs? Using field experiments and observations, we examined factors affecting mutualism stability in six fig tree-fig wasp species pairs. We experimentally compared the ...
متن کاملMolecular markers reveal reproductive strategies of non-pollinating fig wasps : Molecular revelation of fig wasp behaviour
1. Fig wasps have proved extremely useful study organisms for testing how reproductive decisions evolve in response to population structure. In particular, they provide textbook examples of how natural selection can favour female-biased offspring sex ratios, lethal combat for mates and dimorphic mating strategies. 2. However, previous work has been challenged, because supposedly single species ...
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...
متن کاملLongevity, early emergence and body size in a pollinating fig wasp--implications for stability in a fig-pollinator mutualism.
1. Fig trees (Ficus) are pollinated only by agaonid wasps, whose larvae also gall fig ovules. Each ovule develops into either a seed (when pollinated) or a wasp (when an egg is also laid inside) but not both. 2. Ovipositing wasps (foundresses) favour ovules near the centre of the enclosed inflorescence (syconium or 'fig'), leaving ovules near the outer wall to develop into seeds. This spatial s...
متن کاملDisturbance effects on community structure of Ficus tinctoria fig wasps in Xishuangbanna, China: Implications for the fig/fig wasp mutualism
Fig trees are important components of tropical forests, because their fruits are eaten by so many vertebrates, but they depend on pollinating fig wasps to produce mature fruits. Disturbance to habitat structure can have a major impact on insect diversity and composition, potentially reducing fruit yields. We investigated the impact of habitat disturbance on the fig wasp community associated wit...
