In many primates, long excretion lags limit the use of fecal glucocorticoid metabolites (fGCMs) for studying responses to discrete acute stressors. Validated lags to date span a broad but patchy sample of taxa: 22–36 h in catarrhines, such as chimpanzees ( Pan troglodytes) , yellow baboons ( Papio cynocephalus ), and macaques ( Macaca fascicularis) (Palme et al ., 2005 ); greater than 20 h in many callitrichids (Wark et al ., 2016 ); and greater than 24 h in brown spider monkeys ( Ateles hybridus ) and red howler monkeys ( Alouatta seniculus ) (Rimbach et al ., 2013 ).
