Environmental conditions were observed to strongly influence the honey bee efficiency as pollinator and seed-set varied considerably from year to year.
In contrast, few dioecious fig pollinators were caught and the turnover of species between years was substantial.
These patterns are regarded as reflecting adaptations to minimize competition for pollinators.
In these cases, the bees may be opportunistic visitors or facultative pollinators.
Predators of vertebrates are absent and densities of pollinators and seed dispersers are substantially reduced in comparison to the nearby mainland.
We compared the efficiency of foraging habit of one of the major pollinators in effecting pollination.
There is no sign of nectar or any pollinator reward other than pollen in male flowers.
Flowermorph-specific correlation suggests that natural selection by pollinators has moulded trait covariance among floral traits.
