Description
  • The dioecious Clusia nemorosa produces floral resin and it also exhibits floral automimicry. We observed the hourly visitation frequency and behaviour of bee visitors. We hypothesized that the visitation rate will vary between the floral sexes and degree of this variation will differ between the two-reward systems. We found no evidence for visits being exclusively related to resin collection. Deceit pollination appeared to have minor importance. Flower visits that probably facilitated most pollen transfer, combined resin and pollen. The pollinators collected pollen from male flowers and resin from female flowers. The fruit set was not particularly low (44.19%) so offering different rewards by different flower genders has not constrained reproductive success in this system. Overall demand for pollen was greater than demand for resin. Female flowers were visited much less frequently than male flowers.
