Daniel, Antenucci , Roxana R., Zenuto In this work we aimed to evaluate variations in plasma glucocorticoids (GCs, cortisol and corticosterone) levels throughout an annual cycle in free-living male tuco-tucos (Ctenomys talarum) and compare their responses to acute and chronic stressors (trapping, manipulation, immobilization, confinement in a novel environment, transference to captivity). In addition, we used leukocyte profiles to allow discrimination between basal and stress-induced seasonal changes in GC concentrations
