As humans alter landscapes worldwide, land and wildlife managers need reliable tools to assess monitor responses of populations. Glucocorticoid (GC) hormone levels are one common physiological metric used quantify how populations coping in the context their environments. Understanding whether GC can reflect broad landscape characteristics, using data that free commonplace diverse stakeholders, is an important step towards biomarkers having practical application management conservation. We conducted a phylogenetic comparative analysis publicly available datasets test efficacy GCs as biomarker for large spatial-scale avian population monitoring. from HormoneBase (51 species), natural history information US national cover determine if baseline or stress-induced corticosterone varies with amount usable types within each species' home range. found levels, but not baseline, positively correlated per cent both across species. Our results indicate concentrations may be useful characterizing range habitat availability, we advocate more studies on non-traditional species less studied build this framework.

Hormones regulate most physiological functions and life history from embryonic development to reproduction. In addition their roles in growth development, hormones also mediate responses the abiotic, social nutritional environments. Hormone signalling is responsive environmental changes adjust phenotypes prevailing conditions. Both hormone levels receptor densities can change provide a flexible system of regulation. Endocrine flexibility connects environment organismal function, it central understanding impacts effect on individuals populations. may act as 'sensor' link signals epigenetic processes thereby phenotypic plasticity within across generations. Many parameters are now changing unprecedented ways result human activity. The knowledge base organism-environmental interactions was established environments that differ many current conditions ongoing impacts. It an urgent contemporary challenge understand how evolved endocrine will modulate response anthropogenic including climate change, light-at-night chemical pollution. play role ecology, integration into conservation lead more effective outcomes.
