Validation of an enzyme immunoassay for assessing adrenocortical activity and evaluation of factors that affect levels of fecal glucocorticoid metabolites in two New World primates

Highlights • We validated a group-specific fecal glucocorticoid metabolite (FGCM) assay for brown spider monkeys and red howler monkeys. • Spider monkeys show diurnal changes in FGCM levels, howler monkeys do not. • Adults of both species have higher FGCM levels than subadults. • Sex did not affect...

Description
Summary:Highlights • We validated a group-specific fecal glucocorticoid metabolite (FGCM) assay for brown spider monkeys and red howler monkeys. • Spider monkeys show diurnal changes in FGCM levels, howler monkeys do not. • Adults of both species have higher FGCM levels than subadults. • Sex did not affect FGCM levels in neither of the species. • Female spider monkey FGCM levels increased with progressing gestation.
