Comparison of most likely linear and breakpoint models for flight metabolic rate scaling across flying insects.

Model	Slope	St. Err.	P (slope = 0)	P (slope = 0.67)	P (slope = 1)	Intercept		AIC	Akaike weight
Linear	0.98	0.04	<0.001*	<0.001*	0.562	−0.62	NA	139.03	0.003
Break-point	Left: 1.19	0.07	<0.001*	<0.001*	0.027*	−1.03	−0.63	127.34	0.997
	Right: 0.67	0.17	0.004*	0.305	0.004*

The breakpoint model has much higher support using AIC than the standard linear model.
