For each response variable, clutch size and laying probability, minimal adequate models, obtained after backward model selection based on likelihood ratio tests, are given with estimate (Est.), standard error (SE), t- or z-value and P-value associated with each parameter in accordance with the performed models (lmer or glmer). Marginal and conditional R2 (R2 m and R2 c, respectively) were calculated according to [63]
