Seed predation and potential seed dispersers of the narrow endemic Ceratozamianorstogii (Zamiaceae).

ABSTRACT: In this study, we report the observation of potential seed dispersers of the endemic to Mexico and narrowly distributed Ceratozamianorstogii (Zamiaceae). Camera traps were installed in front of two plants of Ceratozamianorstogii and cone phenology until their maturity and disintegration was determined. The female cone of Ceratozamianorstogii has a development of ten months, from the time it emerges until it disintegrates. We were able to identify three stages of cone development: 1) Pre-pollination phase, 2) Pollination phase and 3) Seed maturation phase. Our results support an animal-dispersal hypothesis in Ceratozamia. Three mammals [a mouse (Pteromiscus sp.), a southern spotted skunk (Spilogaleangustifrons) and a kinkajou (Potusflavus)] w
