Results of the AICc model selection procedure used to investigate the effect of syllable number within a call and syllable position on syllable duration in Vespertilio sinensis

Model	Predictive variables	df	LogL	AICc	ΔAICc	wi
1	SyllableN (−)	5	−24,947.17	49,904.36	0.00	0.69
2	SyllableN (−), SPC (+)	6	−24,947.02	49,906.05	1.69	0.30
3	SPC (+)	5	−24,951.81	49,913.63	9.27	<0.01
4	Null	4	−24,955.40	49,918.81	14.45	<0.01

Models are ranked based on the AICc values from the best to the worst model. The sign of the regression coefficient of the associations between syllable duration and syllable number within a call and syllable position is shown in parentheses (“−”: negative; “+”: positive). LogL: Log likelihoods. SyllableN: syllable number within a call. SPC: syllable position in the call.
