Overview

Comprehensive demographic analysis reveals age-specific changes in reproduction and mortality of sea turtles, suggesting conserved life-history strategies across testudines.

Key Points

  • Cumulative egg production in captive green sea turtles increased linearly over two decades, demonstrating sustained reproductive performance.
  • Mortality patterns in sea turtles followed the Gompertz Law, increasing exponentially with age, indicating a decoupling from reproductive output.
  • A unique dataset on captive, known-aged sea turtles reveals no evidence of reproductive senescence even as mortality rates rise.
  • Age-specific changes in sea turtle life history reflect broader phylogenetic patterns found among testudines, suggesting conserved strategies.
