Changes in serum and urinary corticosterone and testosterone during short-term capture and handling in the cane toad (Rhinella marina).
Acute Thermal Stressor Increases Glucocorticoid Response but Minimizes Testosterone and Locomotor Performance in the Cane Toad (Rhinella marina)
TLDR
Exposure acute thermal stressors due to climatic variability could impact amphibians at multiple eco-physiological levels through impacts on endocrine physiology, performance and potentially fitness traits (e.g. reproductive output).
Repeatability of baseline corticosterone and short-term corticosterone stress responses, and their correlation with testosterone and body condition in a terrestrial breeding anuran (Platymantis vitiana).

TLDR
Baseline urinary cortic testosterone, short-term corticosterone responses, urinary estrogen, and progesterone metabolites were highly repeatable for both female groups, highlighting the importance of reproductive and stress hormones during the breeding period in female ground frogs.
ACTH modulation on corticosterone, melatonin, testosterone and innate immune response in the tree frog Hypsiboas faber.

Comparing techniques for measuring corticosterone in tadpoles
TLDR
Comparing the performance of three commonly used procedures for determination of CORT, which presents advantages and disadvantages regarding sensitivity, the use of radioactivity, sample size, handling time, and economic cost, concludes that EIA on whole-body homogenates may be useful to assess qualitative changes in CORT levels when considerable differences are expected.
Acute stress, steroid plasma levels, and innate immunity in Brazilian toads.
Non-invasive monitoring of glucocorticoid physiology within highland and lowland populations of native Australian Great Barred Frog (Mixophyes fasciolatus).
Captivity effects on immune response and steroid plasma levels of a Brazilian toad (Rhinella schneideri)
TLDR
Phagocytosis efficiency was positively associated with T and body condition, suggesting that the effects of chronic stress on reproductive potential and immune response might be associated with the state of energetic reserves.

Changes in urinary testosterone and corticosterone metabolites during short-term confinement with repeated handling in wild male cane toads (Rhinella marina)
TLDR
The finding that testosterone excretion increases rather than decreases after capture in male cane toads shows that it should not be generally assumed that reproductive hormone secretion will decrease after captured in amphibians.

TLDR
It is suggested that the stage of vitellogenesis may modulate the amphibian response to captivity stress and indicate considerable variation among the sex steroid responses of female amphibians to capture.
