Abstract

Background

HPA axis: the pathway that the body takes in response to stress

Adrenocorticotropic hormone (ACTH) tells the adrenal gland to release glucocorticoids which are considered “stress” hormones1

Glucocorticoids (GCs, cortisol and corticosterone) move energy in the body to facilitate flight or flight responses

Prolonged increase of GCs can have a long-term impact on morphology, immune response, and overall survival

In amphibians, glucocorticoids have a role in metamorphosis, so we predicted that different stages of development have a different response in the HPA A

Some stressors of Dyeing Poison Frog (Dendrobates tinctorious) tadpoles are predators, cannibalistic conspecifics, temperature and salinity changes
