1 INTRODUCTION Physiological measures and biomarkers can provide mechanistic insights into how organisms respond to a dynamic landscape of stressors (Chown & Gaston, 2008). The “functional marginality” (Shultz et al., 2021) and “timeline to collapse” (Cerini et al., 2023) frameworks predict that populations in poor quality conditions should display increased biomarkers or signals associated with negative physiological status and poor fitness respectively.
