Social behavior functions and related anatomical characteristics of vasotocin/vasopressin systems in vertebrates
The neuropeptide arginine vasotocin (AVT; non-mammals) and its mammalian homologue, arginine vasopressin (AVP) influence a variety of sex-typical and species-specific behaviors, and provide an… Expand
Alternative male spawning tactics and acoustic signals in the plainfin midshipman fish
The plainfin midshipman Porichthys notatus has two male reproductive morphs, ‘Type I’ and ‘Type II’, which are distinguishable by their physical traits alone. Type I males are eight times larger in… Expand
Temporal coding of species recognition signals in an electric fish.
An electric fish in the African family Mormyridae recognizes members of its own species by "listening" to electric organ discharges, which are species-specific signatures. Reactions of fish in the… Expand
Anatomical Distribution and Cellular Basis for High Levels of Aromatase Activity in the Brain of Teleost Fish: Aromatase Enzyme and mRNA Expression Identify Glia as Source

Although teleost fish have higher levels of brain aromatase activity than any other vertebrate group, its function remains speculative, and no study has identified its cellular basis. A previous… Expand
Sex Steroid Levels in Porichthys notatus, a Fish with Alternative Reproductive Tactics, and a Review of the Hormonal Bases for Male Dimorphism among Teleost Fishes
Plasma levels of 11-ketotestosterone, 11-beta-OH-testosterone, testosterone, and 17-beta-estradiol were measured in reproductive Porichthys notatus, a teleost fish with two male morphs and… Expand
Neural mechanisms and behaviors for acoustic communication in teleost fish
Sound communication is not unique to humans but rather is a trait shared with most non-mammalian vertebrates. A practical way to address questions of vocal signal encoding has been to identify… Expand
Functional analysis of sexual dimorphism in an electric fish, Hypopomus pinnicaudatus, order Gymnotiformes.
Hypopomus pinnicaudatus, an electric fish, has a marked sexual dimorphism in its tail filament. Sexually mature males have long, 'feathered' tails as compared with females. The sexual dimorphism… Expand
Forebrain peptides modulate sexually polymorphic vocal circuitry
The peptide arginine-vasopressin (mammals) and its evolutionary precursor arginine-vasotocin (non-mammals) modulate reproductive physiology and numerous related social behaviours, as do oxytocin… Expand
Behavioral assessment of acoustic parameters relevant to signal recognition and preference in a vocal fish.

Acoustic signal recognition depends on the receiver's processing of the physical attributes of a sound. This study takes advantage of the simple communication sounds produced by plainfin midshipman… Expand
Androgen effects on vocal muscle structure in a teleost fish with inter‐ and intra‐sexual dimorphism
The plainfin midshipman fish Porichthys notatus has both interand intra‐sexual dimorphism in the sound‐producing (vocal or sonic) muscles attached to the swimbladder wall. The “Type I” and “Type II”… Expand
