Overview

Observational analysis reveals high survival rates in sea turtles with energy costs influencing breeding patterns.

Key Points

  • Non-annual nesting leads to high survival rates in sea turtles, linking energy costs to breeding patterns.
  • Sea turtles can experience invariant energy costs during the entire breeding process, from migration to nesting.
  • The opportunity cost of not foraging during breeding contributes to the non-annual nesting strategy.
  • Similar breeding strategies are observed in other species like albatrosses, highlighting broader ecological patterns.
