Locations and attributes of wetlands, ordered from highest to lowest salinity (mg/l Cl), where we collected waterborne CORT, larvae to extract interrenal CORT, water samples to extract ambient CORT or a combination of the aforementioned

For ‘State’: ND indicates North Dakota; MT, Montana.
For ‘Location’: WPA indicates US Fish and Wildlife Service Waterfowl Production Area; NWR, National Wildlife Refuge.
For ‘Larvae’: T = barred tiger salamanders, L = northern leopard frogs, C = boreal chorus frogs; paired baseline and interrenal CORT samples were collected in 2017 and paired baseline and stress-induced CORT samples were collected in 2018.
For ‘Water’: y = replicate water samples collected on the same day in 2019 from several wetlands to assess variation in ambient CORT within wetlands.
Blank cells indicate that no samples were taken at that site in that year.
