Reproductive Effort and Success of Cycas micronesica K.D. Hill Are Affected by Habitat

Cycas micronesica K.D. Hill plants growing in two habitats differing in exposure to wind and salt spray were examined to see whether reproductive effort and success (as gauged by ovule and seed number, respectively) were influenced by abiotic factors as well as by plant size (as gauged by the height of megastrobili above ground). The data were collected via a split-plot design, with plant height nested in habitat type (exposed vs. protected site). Although mean plant height did not differ between the two sites, statistical analyses using a mixed model indicated that plants growing in the protected site had a greater reproductive effort and were more successful than plants growing in the unprotected site; i.e., plant height nested in habitat type had a significant effect. The numbers of ovules and seeds on the windward and leeward sides of each megastrobilus did not differ. Therefore, anemophily could not be confirmed. These data provide (1) the first quantitative demonstration that cycad reproductive effort and success are significantly influenced by abiotic variables such as habitat wind exposure, (2) the first investigation of any of the arborescent cycad species to address the effect of megastrobilus height on pollinator behavior, and (3) evidence that habitat type may have a significant effect on conservation efforts for this and other endangered cycad species.
