- Gaussian families were used for Simpson and Shannon regression and Poisson family for richness. The effect of site (Chizé as reference), age (adult as reference) and sex (females as reference) and the interaction between them are reported when included in the selected models. Parameter estimates with SE are reported with the corresponding z-value (Poisson family) or t-value (Gaussian family) and P-value. Statistical significance is represented by *P < 0.05, **P < 0.01 and ***P < 0.001. TF: Trois Fontaines; Y: young
