Survival differences between the high and low RE females and whether the tactic was rare or common in the population.

Notes: The analyses of generalized linear mixed models are performed both at the individual level (individual values formed the dependent variable) and population level (population means formed the dependent variable). At the individual level, the random effect of population (enclosure) is included in the models (Estimate = 0.046, P = 0.339). df1 = numerator df, df2 = denominator df
