2004 article

Fluoxetine-treated male wrasses exhibit low AVT expression

Semsar, K., Perreault, H. A. N., & Godwin, J. (2004, October 28). Brain Research, Vol. 1029, pp. 141–147.

By: K. Semsar*, H. Perreault n & J. Godwin n 

author keywords: anxiety; depression; vasotocin; serotonin; SSRI; neurosteroidogenesis
MeSH headings : Aggression; Animals; Dominance-Subordination; Fishes / physiology; Fluoxetine / pharmacology; Gene Expression / drug effects; Male; Preoptic Area / drug effects; Preoptic Area / physiology; RNA, Messenger / analysis; Selective Serotonin Reuptake Inhibitors / pharmacology; Vasotocin / genetics
topics (OpenAlex): Neuroendocrine regulation and behavior; Stress Responses and Cortisol; Circadian rhythm and melatonin
TL;DR: 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.

2004 article

Multiple mechanisms of phenotype development in the bluehead wrasse

Semsar, K., & Godwin, J. (2004, April 18). Hormones and Behavior, Vol. 45, pp. 345–353.

By: K. Semsar n & J. Godwin n 

author keywords: vasotocin; vasopressin; androgen; reproductive behavior; social context; organization; activation; sex-typical behavior; aggression; sex change
MeSH headings : Aggression / drug effects; Aggression / physiology; Animals; Antidiuretic Hormone Receptor Antagonists; Arginine Vasopressin / analogs & derivatives; Arginine Vasopressin / pharmacology; Arginine Vasopressin / physiology; Female; Hermaphroditic Organisms; Hormone Antagonists / pharmacology; Male; Ovariectomy; Perciformes / physiology; Phenotype; Sex Determination Processes; Sexual Behavior, Animal / drug effects; Sexual Behavior, Animal / physiology; Territoriality; Testosterone / analogs & derivatives; Testosterone / pharmacology
topics (OpenAlex): Neuroendocrine regulation and behavior; Animal Behavior and Reproduction; Reproductive biology and impacts on aquatic species
TL;DR: 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.

2003 article

Fluoxetine treatment decreases territorial aggression in a coral reef fish

PERREAULT, H., SEMSAR, K., & GODWIN, J. (2003, September 1). Physiology & Behavior, Vol. 79, pp. 719–724.

By: H. Perreault n, K. Semsar n & J. Godwin n 

author keywords: aggression; serotonin; teleost; SSRI; fluoxetine
MeSH headings : Aggression / drug effects; Aggression / physiology; Animals; Fluoxetine / pharmacology; Male; Perciformes / physiology; Serotonin / metabolism; Selective Serotonin Reuptake Inhibitors / pharmacology; Territoriality
topics (OpenAlex): Animal Behavior and Reproduction; Primate Behavior and Ecology; Amphibian and Reptile Biology
TL;DR: 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. (via Semantic Scholar)

2003 article

Social Influences on the Arginine Vasotocin System Are Independent of Gonads in a Sex-Changing Fish

Semsar, K., & Godwin, J. (2003, May 15). Journal of Neuroscience, Vol. 23, pp. 4386–4393.

By: K. Semsar n & J. Godwin n 

MeSH headings : Animals; Arginine Vasopressin / genetics; Arginine Vasopressin / metabolism; Arginine Vasopressin / physiology; Dominance-Subordination; Drug Implants / pharmacology; Female; Fishes; Male; Perciformes; Phenotype; Preoptic Area / chemistry; Preoptic Area / drug effects; Preoptic Area / physiology; RNA, Messenger / metabolism; Sex Characteristics; Sex Determination Processes; Sexual Behavior, Animal / drug effects; Sexual Behavior, Animal / physiology; Social Behavior; Testosterone / analogs & derivatives; Testosterone / metabolism; Testosterone / pharmacology; Vasotocin / genetics; Vasotocin / metabolism; Vasotocin / physiology
topics (OpenAlex): Neuroendocrine regulation and behavior; Animal Behavior and Reproduction; Marine animal studies overview
TL;DR: 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. (via Semantic Scholar)

2001 article

Manipulations of the AVT System Shift Social Status and Related Courtship and Aggressive Behavior in the Bluehead Wrasse

Semsar, K., Kandel, F. L. M., & Godwin, J. (2001, August 1). Hormones and Behavior, Vol. 40, pp. 21–31.

By: K. Semsar n, F. Kandel n & J. Godwin n 

author keywords: arginine vasotocin; vasopressin; aggression; sexual behavior; territoriality; social behavior; alternative reproductive tactics; teleost
MeSH headings : Aggression / physiology; Animals; Dominance-Subordination; Fishes / physiology; Male; Sexual Behavior, Animal / physiology; Social Behavior; Territoriality; Vasotocin / physiology
topics (OpenAlex): Neuroendocrine regulation and behavior; Animal Behavior and Reproduction; Marine animal studies overview
TL;DR: 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. (via Semantic Scholar)
