Figs 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 کاملWeapons and Fighting in Fig Wasps
trypesis caricae, a species in the same genus as the wasp studied by Murray; the numerals 8 and 9 show the elongated eighth and ninth abdominal segments, followed posteriorly by the long sheaths that hold the ovipositor, which is used to drill through the outside wall of the fig into the ovaries of the pistillate florets inside. Right: According to Joseph 9, these are three forms taken by males...
متن کاملBiomechanics of substrate boring by fig wasps.
Female insects of diverse orders bore into substrates to deposit their eggs. Such insects must overcome several biomechanical challenges to successfully oviposit, which include the selection of suitable substrates through which the ovipositor can penetrate without itself fracturing. In many cases, the insect may also need to steer and manipulate the ovipositor within the substrate to deliver eg...
متن کاملSpeciation in fig pollinators and parasites.
Here we draw on phylogenies of figs and fig wasps to suggest how modes of speciation may be affected by interspecific interactions. Mutualists appear to have cospeciated with their hosts to a greater extent than parasites, which showed evidence of host shifting. However, we also repeatedly encountered a pattern not explained by either cospeciation or host switching. Sister species of fig parasi...
متن کاملAncient fig wasps indicate at least 34 Myr of stasis in their mutualism with fig trees.
Fig wasps and fig trees are mutually dependent, with each of the 800 or so species of fig trees (Ficus, Moraceae) typically pollinated by a single species of fig wasp (Hymenoptera: Agaonidae). Molecular evidence suggests that the relationship existed over 65 Ma, during the Cretaceous. Here, we record the discovery of the oldest known fossil fig wasps, from England, dated at 34 Ma. They possess ...
