| Outline of Final Research Achievements |
We investigated the personalities (boldness/exploration) and behavioral plasticity of green sea turtles, which demonstrate their ability to alter their behavior according to the situation, and propose a new method of ex situ conservation in which animals themselves search for new habitats, nesting beach, and return to the sea. To select individuals in which this new method would be applied, laboratory experiments were conducted to investigate the personality (boldness/exploration) of individuals with high behavioral plasticity. The results revealed that bold and highly exploratory individuals have increased behavioral plasticity. We also investigated the relationship between the identified personalities of the turtles and the home range for foraging in the sea. Further, the range of movement was related to exploration regardless of boldness.
