  1. Results from (Generalized) Linear Mixed Models (cohort = random effect) assessing the effects of different levels of anthropogenic noise on fitness-related life-history (A), reproduction (B), and immunity (C) traits. Bold indicates significant results after Bonferroni adjustment, α = 0.0033. The ovary model dropped the mated coefficient because the fixed-effect model matrix was rank deficient
