Associations between glucocorticoids and sociality across a continuum of vertebrate social behavior.

摘要: The causes and consequences of individual differences in animal behavior stress physiology are increasingly studied wild animals, yet the possibility that underlies variation social has received less attention. In this review, we bring together these study areas focus on understanding how activity vertebrate neuroendocrine axis (HPA-axis) may underlie animals. We first describe a continuum behaviors spanning from initial tendencies (proactive behavior) to occurring reproductive contexts (parental care, sexual pair-bonding) lastly nonreproductive (nonsexual bonding, group-level cooperation). then perform qualitative review existing literature address correlative causal association between measures HPA-axis (glucocorticoid levels or GCs) each types behavior. As expected, elevated can inhibit associated with (approaching conspecifics) reproduction. However, also enhance more elaborate outside contexts, such as alloparental care addition, effect GCs depend upon sociality stressor (cause increase severity (extent GCs). Our shows while associations responses diverse, role behind shift toward facilitating inhibiting species, providing insight into systems co-evolve.
