open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Corticosterone (cort) is increasingly used as a biomarker in wildlife conservation, though debate remains over which measures best capture physiological and environmental relationships. Using structural equation modeling on a 14‐year dataset, we evaluated the total hormone, free hormone, and CBG profile hypotheses linking cort, energetic state, and ...
