The "Challenge Hypothesis": Theoretical Implications for Patterns of Testosterone Secretion, Mating Systems, and Breeding Strategies
This model indicates that there may be widely different hormonal responses to male-male and male-female interactions and presumably equally plastic neural mechanisms for the transduction of these signals into endocrine secretions.
The concept of allostasis in biology and biomedicine
ECOLOGICAL BASES OF HORMONE-BEHAVIOR INTERACTIONS : THE EMERGENCY LIFE HISTORY STAGE
Field work reveals that changes in responsiveness to LPFs have ecological bases, such as reproductive state, body condition etc., that in turn indicate different hormonal control mechanisms in the HPA cascade.
Reproduction and Resistance to Stress: When and How
Four mechanisms underlying resistance of the gonadal axis to stress are suggested, likely genetically determined, and their expression may depend upon a complex interaction with environmental factors.
Do baseline glucocorticoids predict fitness?
The Darwinian concept of stress: benefits of allostasis and costs of allostatic load and the trade-offs in health and disease
Actions of glucocorticoids at a seasonal baseline as compared to stress-related levels in the regulation of periodic life processes.
Maternal corticosterone is transferred to avian yolk and may alter offspring growth and adult phenotype.
Corticosterone facilitates begging and affects resource allocation in the black-legged kittiwake
Two functional implications are suggested of the increased corticosterone secretion during food shortages in the black-legged kittiwake: it facilitates begging in chicks, and it affects time allocated by parents to guarding young at the nest.
Dynamics of food availability, body condition and physiological stress response in breeding Black‐legged Kittiwakes
The results suggest that, in addition to a seasonal change in bird physiology during reproduction, local ecological factors such as food availability affect circulating levels of corticosterone and adrenal response to acute stress.
