Observed and predicted values of the number seeds in litter traps (LT) according to the best ZANB model (formula: LT~GQ * species|species + month). a Count part: the estimate seed production in LT from seeds counted in ground quadrats (0.25 m2) is different for the three sampled species. b Zero model: the probability of having a positive seed count (instead of a zero) is higher in November (month 11) for all species and it is different across species
