Abstract This review consolidates current knowledge on mammalian parental care, focusing its neural mechanisms, evolutionary origins, and derivatives. Neurobiological studies have identified specific neurons in the medial preoptic area as crucial for care. Unexpectedly, these are characterized by expression of molecules signaling satiety, such calcitonin receptor BRS3, overlap with involved reproductive behaviors males but not females. A synthesis comparative ecology paleontology suggests an scenario possibly stemming from male‐biased guarding offspring basal vertebrates.

Abstract Vocalizations communicate information indicative of behavioural state across divergent social contexts. Yet, how brain regions actively pattern the acoustic features context-specific vocal signals remains largely unexplored. The midbrain periaqueductal gray (PAG) is a major site for initiating vocalization among mammals, including primates. We show that PAG neurons in highly fish species ( Porichthys notatus ) are activated distinct patterns during agonistic versus courtship calling by males, with few co-activated non-vocal behaviour, foraging. Pharmacological manipulations within vocally active PAG, but not hindbrain, sites evoke network output to sonic muscles matching temporal and calls, showing balance inhibitory excitatory dynamics likely necessary patterning different call types. Collectively, these findings support hypothesis mammals share functionally comparable nodes some can influence structure signals.

Recent studies in mice demonstrate that a subset of neurons the medial preoptic area (MPOA) express galanin play crucial roles regulating parental behavior both sexes. However, little information is available on function social behaviors other species. Here, we report that, medaka, MPOA occurred nearly exclusively males, resulting from testicular androgen stimulation. Galanin-deficient medaka showed greatly reduced incidence male–male aggressive chases. Furthermore, while treatment female with induced male-typical acts, deficiency these females attenuated effect Given their male-biased and androgen-dependent nature, most likely mediate Histological further suggested variability projection targets may account for species-dependent functional differences evolutionarily conserved neural substrates.

Abstract Nests are the key elements of reproductive repertoire several fish species. Understanding physiological aspects behind their nesting behaviour is imperative to improve our knowledge about behavioural mechanisms focusing on species conservation. Nevertheless, current still underexplored. Here, we show a synthesis based an integrative approach for understanding diversity in fish. Because nest sometimes does not involve new buildings (as birds), suggest more comprehensive definition instead structure per se. Forty families were recorded as they made nests, which sorted into six main types: bowls, burrows, foam nests plant matter and animal parts, besides clean rock surfaces. Besides spawning parental care, these also serve refuge against predators male competitors, targets sexual selection, including bowers with no care function, badges social status. We showed that, although it advantageous what Darwinian fitness concerned, requires time energy. propose evolution types functions, from ancestral bowl used derived selection functions.

Abstract Adult male animals typically court and attempt to mate with females, while attacking other males. Emerging evidence from mice indicates that neurons expressing the estrogen receptor ESR1 in behaviorally relevant brain regions play a central role mediating these mutually exclusive behavioral responses conspecifics. However, findings are unlikely apply most vertebrates, where androgens — rather than estrogens have been implicated behaviors. Here we report medaka ( Oryzias latipes ) lacking one of two androgen subtypes (Ara) less aggressive toward males instead actively them, those subtype (Arb) motivated females conversely attack them. These indicate that, medaka, Ara- Arb-mediated signaling pathways facilitate appropriate responses, simultaneously suppressing inappropriate respectively. Notably, either retain ability discriminate sex conspecifics, suggesting defect subsequent decision-making process or fight. We further show Ara Arb expressed intermingled but largely distinct populations neurons, stimulate expression different genes including galanin vasotocin, Collectively, our results demonstrate teleosts make adaptive decisions fight as result activation complementary pathways, depending on conspecific they encounter.

Spexin (SPX) and galanin (GAL) are two neuropeptides that phylogenetically related have descended from a common ancestral gene. Considerable attention has been given to these multifunctional because they share GAL receptors 1,2, 3. Since SPX-synthesizing neurons detected in several brain areas, therefore, it can be speculated SPX involved various neurophysiological functions.
