Pituitary–adrenocortical and gonadal endocrine activity was investigated in a captive colony of Pteropus vampyrus, a highly social Old World fruit bat. Both cortisol and corticosterone were present in plasma, at a ratio of approximately 5:1, respectively. Glucocorticoid but not testosterone levels significantly increased prior to and concomitant with the evening active period. Restraint stress for 15–60 min resulted in a significant and rapid increase in plasma levels of adrenocorticotropic… CONTINUE READING
