  1. P-values indicate approximate significance of GAMM smooth terms based on Chi-sq. statistics. Second column indicates the number of times each environmental variable105,106,107,108,109 was determined to be significant (based on p-value < 0.05) under the resampling procedure (n = 100 iterations, resampling randomly from the state-space model posterior estimates for behavioural state and location).
