Table 1. Changes in behavioral stress responses among experimental species.

Species	Dwelling	R 0			Asym			k
		Mean±SE	t	P	Mean±SE	t	P	Mean±SE	t	P
Movement duration of T. rosa and freezing duration of T. longibarbata were estimated using linear models; those of other species were estimated using self-starting nonlinear asymptotic models. In the regression model, R0 represents initial value of the dependent variable at time zero, Asym is the asymptotic value, and k is the rate constant. N/A: Not available.
