| time in tortoiseshell: a bomb radiocarbon-validated chronology in sea turtle scutes. | some of the most basic questions of sea turtle life history are also the most elusive. many uncertainties surround lifespan, growth rates, maturity and spatial structure, yet these are critical factors in assessing population status. here we examine the keratinized hard tissues of the hawksbill (eretmochelys imbricata) carapace and use bomb radiocarbon dating to estimate growth and maturity. scutes have an established dietary record, yet the large keratin deposits of hawksbills evoke a reliable ... | 2016 | 26740617 |
