Braz Titon

TL;DR: It is shown that for R. icterica restraint for 24h proved to be a stressful condition, increasing CORT by 3-fold without consistent immunological changes, but the application of a more intense stressor (restraint with movement restriction), for the same period, potentiated this response resulting in a 9-fold increase in CORT.

TL;DR: Comparisons of water balance and the sensitivity of locomotor performance to dehydration at different temperatures for three species of toads from the genus Rhinella show patterns associated to interspecific differences in both geographical distribution and time of seasonal reproduction.

TL;DR: Time-related changes in immune response and corticosterone plasma levels following restraint challenge, short, mid and long-term captivity, and CORT exogenous administration by transdermal application in Rhinella ornata toads are described and immuno-enhancing effects following restraint are demonstrated.

TL;DR: The hormonal changes observed in response to ACTH treatment suggest that stressors could act as inhibitors of reproductive activity, as well as differentially modulating melatonin levels at different time-points.

TL;DR: Comparison of resistance to evaporative water loss, rehydration rates and sensitivity of locomotor performance to variations on hydration level and temperature was performed for five species of Bufonidae toads inhabiting different Brazilian biomes to suggest adaptation patterns to environmental conditions.
