Intrapopulation variability in the timing of ontogenetichabitat shifts in sea turtles revealed using d15N valuesfrom bone growth rings
Determining location and timing of ontogenetic shifts in the habitat use of highly migratory species, along with possible intrapopulation variation in these shifts, is essential for understanding mechanisms driving alternate life histories and assessing overall population trends. Measuring variations in multi-year habitat-use patterns is especially difficult for remote oceanic species.
