Variation in age and size at sexual maturity in Kemp’s ridley sea turtles

open access: yesEndangered Species Research, 2014
Age at sexual maturity (AgeSM) is one of the most serious demographic data gaps for sea turtle populations. Better estimates of AgeSM and associated variance would improve evaluation of population dynamics and responses of populations to disturbances and
