(A) Significant increase in the proportion of male green treefrogs that resumed spontaneous calling following and IP injection of 20 μg arginine vasotocin (AVT) compared to vehicle (saline) injection. (B) Significant increase in plasma corticosterone (mean + SEM) following injection with 20 μg AVT compared to vehicle (saline) injection. Results show that AVT increases calling even when stimulating corticosteroid release. N = 10 males per group. From data in Burmeister et al. (68).
