Arginine vasotocin (AVT) and its mammalian homologoue arginine vasopressin (AVP) influence male sexual and aggressive behaviors in many species. We tested the effects of AVT and an AVP-V(1a) receptor antagonist on the display of alternative male tactics in a tropical coral reef fish, the bluehead wrasse Thalassoma bifasciatum. We gave AVT injections to territorial and nonterritorial males of the large and colorful phenotype (terminal phase) and an AVP-V(1a) receptor antagonist, Manning compound… Expand
Individual Behavioral and Neuronal Phenotypes for Arginine Vasotocin Mediated Courtship and Aggression in a Territorial Teleost
TLDR
The results suggest a differential involvement of preoptic AVT neurons and/or their receptors in supporting the expression of aggression and courtship and match similar behavioral and immunoreactive patterns of neuropeptide secretion in other taxa. Expand
Effects of central vasotocin and mesotocin manipulations on social behavior in male and female zebra finches
TLDR
A modest dose-dependent facilitation of aggression by VT, but not MT, in both male and female finches is demonstrated, and partner preference is not readily induced by VT or MT in this species in contrast to rodents. Expand
Arginine vasotocin effects on courtship behavior in male white perch (Morone americana)
TLDR
The strong behavioral effects observed with ICV administration support a central site of action for AVT in stimulating attending behavior, providing further evidence of a conserved behavioral role for these peptides. Expand
Arginine vasotocin activates advertisement calling and movement in the territorial Puerto Rican frog, Eleutherodactylus coqui
TLDR
It is concluded that AVT stimulates advertisement calling and AVT-activated males displayed territorial characteristics of E. coqui. Expand
Arginine vasotocin neuronal phenotypes and their relationship to aggressive behavior in the territorial monogamous multiband butterflyfish, Chaetodon multicinctus
TLDR
This study provides further support for the relationship between AVT neuronal features and aggression in fishes, and provides preliminary evidence that this relationship may relate to the motivation to produce aggressive behaviors in the immediate future. Expand
Neuropeptide regulation of social behavior in a monogamous cichlid fish
TLDR
The results indicate that the basic social behaviors typically mediated by the AVP/OT pathways may provide the building blocks necessary for monogamous mating behavior. Expand
Hormone levels in territorial and non-territorial male collared lizards
TLDR
Compared plasma levels of testosterone, dihydrotestosterone, and corticosterone in 2y+-collared lizard males that defended territories with those of first-year males that were mature, but did not defend territories, this result suggests that high rates of aggression do not alter plasma steroids, although behavioral manipulations are needed to more fully test this hypothesis. Expand
New insights into neuropeptide modulation of aggression: field studies of arginine vasotocin in a territorial tropical damselfish
TLDR
The pattern revealed here for damselfish may be symptomatic of species- and context-dependent specificity of AVT's modulation of aggression across teleosts, as is currently proposed for tetrapods. Expand
Arginine vasotocin and androgen pathways are associated with mating system variation in North American cichlid fishes
Neuroendocrine pathways that regulate social behavior are remarkably conserved across divergent taxa. The neuropeptides arginine vasotocin/vasopressin (AVT/AVP) and their receptor V1a mediateExpand
Arginine vasotocin, steroid hormones and social behavior in the green anole lizard (Anolis carolinensis)
TLDR
It is found that AVT tended to reduce aggressive behavior as has been reported for other territorial species, and a role for AVT in the regulation of reptile social behavior is supported. Expand

TLDR
Song and overt aggression appear be modulated independently by septal neuropeptides, and sePTal AVT and VIP function may differ between species which differ in the expression of territorial or colonial social organizations. Expand

TLDR
AVT infusions administered via chronic guide cannulae directed at the septum significantly inhibited aggressive behavior, consistent with results in the territorial field sparrow, supporting the hypothesis that social organization is correlated with AVT function. Expand
Androgen control of social status in males of a wild population of stoplight parrotfish, Sparisoma viride (Scaridae)
TLDR
It is suggested that the endocrine system plays a role in fine-tuning the levels of territorial aggression exhibited by male stoplight parrotfish, as well as in recent theory in behavioral endocrinology. Expand

Results from research on T. granulosa illustrate how steroid-peptide interactions in the control of behaviors entail multiple neuroanatomical sites and neurochemical actions. Expand
Increased affiliative response to vasopressin in mice expressing the V1a receptor from a monogamous vole
TLDR
It is shown that centrally administered arginine vasopressin increases affiliative behaviour in the highly social, monogamous prairie vole, but not in the relatively asocial, promiscuous montane vole. Expand

TLDR
Examination of aggression and flank marking in pairs of male hamsters with intact flank glands, and when one or both members of a pair had their flank glands removed found that social status was determined by the level of overt aggression during the initial encounters. Expand
Effect of Intraseptal Vasotocin and Vasoactive Intestinal Polypeptide Infusions on Courtship Song and Aggression in the Male Zebra Finch (Taeniopygia guttata)
TLDR
Comparison with findings in mammals suggests that modulation of aggression by septal AVT (or AVP) is evolutionarily conserved in vertebrates, but modulation of aggressive behaviour by VIP has not previously been reported for any vertebrate. Expand

TLDR
The profile area, or size, of AVT-ir POA neurons differed across the four classes of midshipman and was strongly correlated to differences in body size among the groups, and the number of POA cells containing AVT is likely to be set early in development and not to change with the growth of the animal.

Arginine Vasotocin Injection Increases Probability of Calling in Cricket Frogs, but Causes Call Changes Characteristic of Less Aggressive Males
TLDR
It is found that the peptide hormone arginine vasotocin (AVT) not only increased the probability that males called after injections, but also caused modifications in middle and end calls to produce calls characteristic of less aggressive males. Expand
Arginine vasotocin increases calling-site acquisition by nonresident male grey treefrogs
TLDR
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
