报告摘要： Fig and fig wasps comprised the most species-specific mutualistic system in the world, but the mechanisms underlying maintenance of this system is still largely unclear. One of the possible factors that may affect the stability of fig-fig wasp system is the spatial stratification of galls occupied by fig wasps and the pollinated ovules, namely seeds, in a fig. In this presentation, we showed that such spatial pattern had been observed in many fig species and the most likely explanation was linked to the natural enemies of fig wasps and the match between female flower styles and ovipositors of fig wasps. Further studies focusing on the genetic background contributing to parasitoid-host relationships and functional traits evolution are also necessary in the future.
