ResumenWe studied how fecal age (6, 12, 24, 48, 72, and 168 h) and seasonality affect variation in the fecal steroid hormone metabolite concentration in three endangered mammalian species, Mhorr gazelle, Saharan Barbary sheep, and the Iberian lynx. Except for estrogens, concentrations remained stable for at least 48 h in the Mhorr gazelle and the Saharan Barbary sheep. Steroid hormone metabolite concentration remained stable in the Iberian lynx through- out the experiment (1 week). Seasonality was the main factor affecting variation in hormone metabolite concen- trations, and although the response was species- and hormone-specific, the dry season resulted in increased hormone metabolite concentrations, while the wet season reduced the concentration.
