All the environmental and anthropogenic variables were standardized to zero mean and unit variance prior to model fitting, and a quadratic term for each of the standardized temperature variables was also created to introduce nonlinear effects. Estimates are posterior median and equal tailed 95% credible intervals

*Refers to the posterior estimate of the standard deviation of the spatial random effect

** Refers to the posterior estimate of the standard deviation of the independent second-order increment in the temporally structured effect

§Each regression parameter (i.e. intercept and the coefficients of the fixed effects) was assigned a normal prior N0,52. We assumed a logGamma1,0.01 prior on the logarithm of the precision of the spatial random effects and independent second-order increment in the temporally structured effect. The default penalized complexity prior in R-INLA was specified for the logarithm of the negative binomial size parameter
