Summary of the GAM analyses on binary data to test the effect of note duration and note frequency on male reaction to the playback of synthetic calls in five frog species

Species	n	DE, %	Predictor	df	Deviance	P
Am. hahneli	57	16.2	Peak frequency	−2.9	−6.23	0.0925
			Note duration	−3.0	−10.9	0.0118
Am. picta	31	20.9	Peak frequency	−3.1	−6.40	0.0974
			Note duration	−2.8	−5.45	0.1243
Am. trivittata	51	33.2	Peak frequency	−0.6	−4.6	0.0148
			Note duration	−4.3	−19.0	0.0011
Allobates sp. 1	51	36.8	Peak frequency	−3.5	−17.4	0.0010
			Note duration	−3.0	−11.9	0.0075
A. femoralis	63	43.8	Peak frequency	−3.0	−18.6	0.0003
			Note duration	−3.5	−19.1	0.0004

The ability of the model to predict the outcome of the playback experiments is expressed as the percentage of deviation explained (DE).
