The role of seagrass dispersal by marine mega-herbivores, dugong (Dugong dugon) and green sea turtles (Chelonia mydas). (Old ID 22411)
Role
Principal Investigator
Description
This project will investigate the dispersal mechanisms of tropical seagrasses and determine which mechanisms are most effective for long distance dispersal. It will examine whether marine mega-herbivores (dugongs and green sea turtles) disperse seagrass seeds through their fecal matter and whether those seeds are viable. It will determine how long seagrass fragments, created by abiotic and biotic mechanisms, remain viable and establish new meadows. This information will be used to model which seagrass meadows are at greater risk of slow recovery after a large scale loss. This recovery model will have the potential to highlight which seagrass meadows rely solely on dispersal by marine mega-herbivores for recovery.
