Summary of generalized linear mixed models (GLMMs) and linear models (LMs). The results of generalized linear mixed models (GLMMs) and linear models (LMs). (a)(b): GLMM with each response variable and the explanatory variable shown in Figure 2b. GLMM includes individual as a random effect. (c)–(g): LM with each response variable and the explanatory variable shown in Figures 2c,d and 3a–c. In all GLMMs and LMs, Akaike's information criterion corrected for small samples (AICc), intercept, and slope coefficient are shown for each model. Also, marginal R 2 and R 2 are shown in each GLMM and LM, respectively. The models with the lower AICc are shown in bold (where ΔAICc > 2) or italic type (where ΔAICc <2)
