Abstract: In a human-dominated landscape such as Singapore¿s, figs play an important role in providing sustenance for a variety of urban wildlife. The focus of this study was on four species of dioecious pioneer figs that grow in abandoned or disturbed habitats: F. grossularioides, F. fistulosa, F. variegata and F. aurata. The phenology and pollination biology of the fig plants and the dispersal and longevity of the pollinating fig wasps were studied. In particular, the phenology of F. grossularioides and F. aurata displayed the potential for gaps in phenology which could threaten the local persistence of pollinator populations. The pollinators of these dioecious species appear to disperse shorter distances and closer to the ground. The already short adult lives of the pollinators (< 2 days) were reduced further by high temperatures (> 32oC). While all four species are currently doing well in the highly urbanized landscape of Singapore, they may be vulnerable to rising temperatures and extended droughts in the future.
