How to be a fig wasp.
In the two decades since Janzen described how to be a fig, more than 200 papers have appeared on fig wasps (Agaonidae) and their host plants (Ficus spp., Moraceae). Fig pollination is now widely regarded as a model system for the study of coevolved mutualism, and earlier reviews have focused on the evolution of resource conflicts between pollinating fig wasps, their hosts, and their parasites. ...
متن کاملAsymmetric interaction and indeterminate fitness correlation between cooperative partners in the fig–fig wasp mutualism
Empirical observations have shown that cooperative partners can compete for common resources, but what factors determine whether partners cooperate or compete remain unclear. Using the reciprocal fig-fig wasp mutualism, we show that nonlinear amplification of interference competition between fig wasps-which limits the fig wasps' ability to use a common resource (i.e. female flowers)-keeps the c...
متن کاملHow to Be a Fig
The 900-odd species of Ficus (20, 21) constitute the most distinctive of the widespread genera of tropical plants. Figs have (a) a complex obligatory mutualism with their pollinating agaonid fig wasps, yet are found in almost all tropical habitat types and geographic locations [this sets them apart from ant-acacias (63-65), euglossine-orchids (24,26), moth-yuccas (45, 88, 89,), ant-epiphytes (6...
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 کاملTrade-off between reciprocal mutualists: local resource availability-oriented interaction in fig/fig wasp mutualism.
1. The mechanisms that prevent competition (conflict) between the recipient and co-operative actor in co-operative systems remain one of the greatest problems for evolutionary biology. Previous hypotheses suggest that self-restraint, dispersal or spatial constraints can prevent direct competition for local resources or any other common resources, thereby maintaining stable co-operation interact...
