... of this study was to investigate body water dynamics in the estuarine diamondback terrapin ( Malaclemys terrapin ), a species that undergoes seasonal dormancy in salt marsh habitats. We conducted a field study to determine the total body water (%TBW), water turnover rate (WTR) and daily water flux (DWF...

Urine production was 53 ml kg -1 day -1 in the dry season but 111 ml kg -1 day -1 in the wet season, while water flux rates were 140 ml kg -1 day -1 and 280 ml kg -1 day -1 ,respectively. Serotonin but not dopamine increased urine...
