Additionally, my findings revealed the context-dependent nature of repeatability in measures of boldness.

The second study examined how both behavior and physiology contribute to the invasive success of Eleutherodactylus coquí. In the field, I noted density-dependent behavioral variations influenced by elevational gradients. I also observed plastic responses after introducing frogs to a novel environment, with all frogs reducing activity, exploration, and boldness in the lab as compared to the field. Lastly, I found correlations within and between activity, exploration, and physiology (resting metabolic rate). These results emphasize the need to consider behavior, alongside abiotic and biotic influences, to understand the expansion and persistence of invasive species.
