Table 1. Individual mean fecal glucocorticoid metabolite concentrations in captive Grévy’s zebra mares, per time period.

Individual mean fGCM concentrations (ng/g ww) ± standard deviation in captive Grévy’s zebra mares, for each respective time period (before: 6 to 1 days before translocation event; separate 1: 0 to 4 days after translocation, separate enclosures; common: 5 to 9 days after translocation, common enclosure; separate 2: 10–14 days after translocation, separate enclosures).
