Abstract
Personality is inter-individual differences consistent across time and contexts, and behavioral syndromes are correlations between two or more of personality axes among individuals . Relatively little is known about the development of personality, particularly in species that undergo major developmental shifts such as frog metamorphosis. This study evaluates whether personality and behavioral syndrome are consistent or changing as Ranitomeya imitator poison frog tadpoles develop. We focus on the exploration, activity, and boldness personality axes, using both an open field test and a shelter test. Each tadpole underwent four replicates per assay type every other week until they metamorphosed (~ 2 mo). We found that activity and exploration were more repeatable than boldness, and these two personality axes stabilized and became more repeatable as the tadpoles developed. Activity and exploration decreased with age, while boldness did not. There were also strong correlations among personality axes, indicating behavioral syndromes. Our results suggest that distinct personality axes may exhibit different developmental patterns and that personality becomes more solidified with age.
