You are what you eat (nitrogen) and where you eat it (carbon)Project lifecycle
What? Flatback turtles are tissue-biopsied at the nesting ground, then satellite tracked to a verified foraging ground. Lab results give insight from chemical signatures (carbon and nitrogen) that are unique to the foraging grounds.
Why? The foraging ground is the location that lipids are stored to fuel a reproductive migration. Sea turtles are capital breeders that have reproductive outputs and cycles based on stored energy.
What have we found? The foraging ground distances to migrate (distance travelled) and remigration intervals (years between breeding) will strongly influence how the stored energy is spent on female reproductive output (number of annual nests).
