Social behavior functions and related anatomical characteristics of vasotocin/vasopressin systems in vertebrates
TLDR
A comprehensive review of the available literature on social behavior functions of AVT/AVP and related anatomical characteristics, inclusive of seasonal plasticity, sexual dimorphism, and steroid sensitivity is provided. Expand
Alternative male spawning tactics and acoustic signals in the plainfin midshipman fish
TLDR
The dimorphic body and vocal muscle traits of the two male morphs in the plainfin midshipman are paralleled by a divergence in their reproductive tactics and the properties of their acoustic signals. 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
TLDR
This is the first study to identify aromatase expression mostly, if not entirely, in glial cells under normal rather than brain injury-dependent conditions, and may represent an adaptation linked to continual neurogenesis that is known to occur throughout an individual's lifetime among fishes. 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 theExpand
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
TLDR
A review of endocrine data from six different species with male dimorphism shows consistent differences between morphotypes and a striking pattern: 11-ketotestosterone levels are uniformly elevated in each "courting male" morphotype relative to its "noncourting" conspecific. Expand
Midbrain acoustic circuitry in a vocalizing fish
TLDR
The results indicate a general pattern of acoustic circuitry similar to that of specialists, and show central adaptations, namely, a vocal–acoustic interface in DO and SO related to this species' vocal abilities. Expand
Neural mechanisms and behaviors for acoustic communication in teleost fish
TLDR
This work focuses on those vocal species where combined behavioral and neurobiological studies have recently begun to elucidate a suite of adaptations for both the production and the perception of acoustic signals essential to their reproductive success and survival. Expand
Functional analysis of sexual dimorphism in an electric fish, Hypopomus pinnicaudatus, order Gymnotiformes.
TLDR
Female choice probably played a role in the evolution of long duration EODs among males, and males may have secondarily grown long tails to compensate for the loss in active space that would otherwise accompany a weaker EOD. Expand
Forebrain peptides modulate sexually polymorphic vocal circuitry
TLDR
Neurophysiological evidence is presented that males with vocal characteristics typical of females share a pattern of neuropeptide function with females rather than conspecific males, showing that the neuromodulatory mechanisms that establish reproduction-related behaviour can be dissociated from gonadal sex. Expand
Behavioral assessment of acoustic parameters relevant to signal recognition and preference in a vocal fish.

TLDR
The results demonstrate that phonotactic assessment of stimulus relevance can be applied in a teleost fish, and that multiple signal parameters can affect receiver response in a vertebrate with relatively simple communication signals. Expand
