Pollination and parasitism in functionally dioecious figs.
Fig wasps (Agaonidae: Hymenoptera) are seed predators and their interactions with Ficus species (Moraceae) range from mutualism to parasitism. Recently considerable attention has been paid to conflicts of interest between the mutualists and how they are resolved in monoecious fig species. However, despite the fact that different conflicts can arise, little is known about the factors that influe...
متن کاملPollinator sharing in dioecious figs (Ficus: Moraceae)
As one of the most specialized pollination syndromes, the fig (Ficus)–fig wasp (Agaonidae) mutualism can shed light on how pollinator behaviour and specificity affect plant diversification through processes such as reproductive isolation and hybridization. Pollinator sharing among species has important implications for Ficus species delimitation and the evolutionary history of the mutualism. Al...
متن کاملNutritional Dimorphism in New Guinea Dioecious Figs
The life history of figs (Ficus, Moraceae) involves pollination by specialized insects and seed dispersal by vertebrate frugivores. This three-way interaction raises the possibility of conflict between pollinators and seed dispersers over fig resources. The conflict might be mediated in dioecious figs by the segregation of inflorescences with specialized male and female sexual functions, termed...
متن کاملThe incidence and pattern of copollinator diversification in dioecious and monoecious figs
Differences in breeding system are associated with correlated ecological and morphological changes in plants. In Ficus, dioecy and monoecy are strongly associated with different suites of traits (tree height, population density, fruiting frequency, pollinator dispersal ecology). Although approximately 30% of fig species are pollinated by multiple species of fig-pollinating wasps, it has been su...
متن کاملDevelopment and characterization of microsatellite loci in dioecious figs (Ficus, Moraceae).
PREMISE OF THE STUDY Microsatellite markers for dioecious fig species, Ficus bernaysii King (section Sycocarpus), Ficus pachyrrhachis K. Schum. & Lauterb. (section Sycocarpus), and Ficus copiosa Steud. (section Sycidium) were developed to estimate gene flow among closely related fig species. METHODS AND RESULTS Loci were developed from tri- and tetranucleotide-enriched genomic libraries. The ...
