This study demonstrates that fecal glucocorticoid levels are a useful measure of diverse stressors in dugongs (a vulnerable cryptic marine mammal), including cold temperature and other seasonal factors, intraspecific aggression/injury, and pregnancy. The intrinsic underlying glucocorticoid patterns of dugongs are different between sexes, across reproductive maturity states, and vary seasonally in response to reproductive patterns and environmental conditions.
