Manipulations of the AVT System Shift Social Status and Related Courtship and Aggressive Behavior in the Bluehead Wrasse
The results suggest that the AVT system may play a key role in motivation of behaviors related to mating in a tropical coral reef fish, the bluehead wrasse Thalassoma bifasciatum. Expand
Fluoxetine treatment decreases territorial aggression in a coral reef fish
Fluoxetine is used to experimentally enhance serotonergic neurotransmission in a territorial coral reef fish and supports the link between serotonin and aggressive behavior in fishes in both a controlled laboratory testing environment and the animal's natural habitat. Expand
Social Influences on the Arginine Vasotocin System Are Independent of Gonads in a Sex-Changing Fish
The results demonstrate that the AVT neural phenotype in the bluehead wrasse can be strongly influenced by social status, and that these social influences can be manifested independent of gonads. Expand
Fluoxetine-treated male wrasses exhibit low AVT expression
The hypothesis that behavioral effects of SSRIs may be mediated in part through interactions with the AVT/AVP system is experimentally supported and SSRI effects on neuroendocrine function may be best modeled in animals with sensitive stress responses such as those found in nondomesticated animals.

Multiple mechanisms of phenotype development in the bluehead wrasse
It is demonstrated that AVT appears necessary for the assumption of dominant territorial status in males and females, but is sufficient only in the socially dominant terminal phase (TP) male phenotype, and that the ability of AVT to induce male-typical behavior differs among sexual phenotypes.

Arginine vasotocin increases calling-site acquisition by nonresident male grey treefrogs
This is the first study demonstrating that AVT manipulations in a natural population can directly influence the outcome of male-male competition for a resource and reverse the resident-male advantage. Expand
Influence of sex and corticotropin-releasing factor pathways as determinants in serotonin sensitivity.
A sensitivity to 5-HT-mediated anxiety in females may underlie a heightened vulnerability to stress-related affective disorders. Expand
Influence of Sex and CRF Pathways as Determinants in 5-HT Sensitivity Abbreviated title: Sex and Stress in 5-HT Sensitivity
This study examined behavioral and physiological responses in male and female stress-sensitive CRF receptor-2 deficient (R2KO) mice and hypothesized that as CRF modulates 5-HT pathways, mice with a genetic disruption in CRF signaling will show a greater sensitivity to changes in local 5- HT in Behavioral and physiological outcomes following acute citalopram treatment.
