The structure of Generalized Linear Mixed Models used to investigate the effects of sex, size (carapace length, CL mm) and infestation intensity on the number of gammarids consumed by Xironogiton victoriensis (Annelida: Clitellata) infested signal crayfish (Pacifastacus leniusculus)

Fixed terms	Random terms	Significant fixed terms	F (incremental)	Df	P
Sex, Size (CL mm), Infestation Intensity, Size: Sex, Sex: Infestation Intensity, Size: Infestation Intensity	Time in experiment, Crayfish ID.	Sex	4.84	1,94	<0.01
		Infestation Intensity	15.83	1,94	0.03
Sex, Size (CL mm), Size: Sex	Time in experiment, Crayfish ID.	Sex	9.38	1,95	<0.01
Infestation Intensity, Sex, Sex: Infestation Intensity	Time in experiment, Crayfish ID.	Sex	10.30	1,94	0.03
		Infestation Intensity	10.36	1,94	<0.01

For significant terms (P ≤ 0.05) the F-statistic, degrees of freedom (df) and P-values are reported
