N2 - Glucocorticoids are thought to mediate the disruption of parental behavior in response to acute and chronic
stress. Previous research supports their role in chronic stress; however, no study has experimentally tested
the effects of acute glucocorticoid elevation on paternal behavior. We tested the prediction that acute corticosterone
(CORT) increases would decrease paternal behavior in California mouse fathers and would lead to
longer-term effects on reproductive success, as even short-term increases in CORT have been shown to produce
lasting effects on the hypothalamic-pituitary-adrenal axis. First-time fathers were injected with 30 mg/
kg CORT, 60 mg/kg CORT or vehicle, or left unmanipulated. Interactions between the male and its pup(s)
were recorded 1.5–2 h after injection and scored for paternal and non-paternal behavior. Treatment groups
were combined into control (unmanipulated+vehicle, n=15) and CORT (30 mg/kg+60 mg/kg, n=16)
for analysis based on resulting plasma CORT concentr
