Table 4. Elasticity values.

Elasticity values calculated from stage structured matrix population models for demographic parameters in temperate (Temp.) and tropical (Trop.) freshwater turtles. Observed elasticities were derived from median values from the scientific literature (S1 Table) and predicted values are from the 95% confidence set of GAM models (Table 3).

Parameter	Observed		Predicted
	Temp.	Trop.	Temp.	Trop.
Egg survival	0.090	0.110	0.076	0.082
Juvenile Pia	0.183	0.252	0.208	0.216
Juvenile Gib	0.090	0.110	0.076	0.082
Adult survival	0.546	0.419	0.564	0.537
Annual fecundityc	0.090	0.110	0.076	0.082

^a Juvenile P_i = probability of a juvenile surviving and remaining in the juvenile stage.

^b Juvenile G_i = probability of a juvenile surviving and “graduating” to the adult stage.

^c Clutch size X number of clutches X breeding frequency
