Members of the genus are characterized by a unique pollination syndrome. Each species is pollinated by and houses the young of a species-specific wasp (see fig wasp). This remarkable pollination system has a fundamental impact on tropical forest ecology. When the pollen-bearing wasp leaves a Ficus plant, the fruit crop ripens quickly, providing a rich feast that attracts a host of mammals and birds. Moreover, as a consequence of the wasp’s short adult lifetime (as little as two days), there are some trees both receiving and releasing fig wasps throughout the year. This pattern results in a steady supply of fruit, making Ficus fruits a critical resource for many animals during times of food shortage. If the plants were to be cut out of a forest or the fig wasps were to somehow be removed, there would almost certainly be a dramatic reduction in animal life, as is suggested by the lower population densities of fruit-eating mammals on small islands that lack Ficus species.
