Table 2 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)

From: Reduced aggression and foraging efficiency of invasive signal crayfish (Pacifastacus leniusculus) infested with non-native branchiobdellidans (Annelida: Clitellata)
