We aimed to evaluate the responses of cortisol, corticosterone, and blood glucose to adrenocorticotropic hormone (ACTH) in males and females of the subterranean rodent Ctenomys talarum and addressed interannual variations in the plasma levels of both hormones. The most important results indicate that: (1) cortisol positively responds to the ACTH signal but corticosterone does not, even though corticosterone...
We validated the Coat‐a‐Count® radioimmunoassay (RIA) kit for measuring testosterone in plasma samples of the subterranean rodent Ctenomys talarum and evaluated testosterone levels in free‐living and captive individuals. The performance of the assay was evaluated by the assessment of parallelism, accuracy and precision. Moreover, the high specificity of the assay antibody was confirmed by high‐pressure...
