Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

open access: yesJournal of Animal Ecology, Volume 95, Issue 8, Page 1326-1338, August 2026.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Arg-Vasotocin Directly Activates Isotocin Receptors and Induces COX2 Expression in Ovoviviparous Guppies

open access: yesFrontiers in Endocrinology, 2021
Oxytocin (OT) is a crucial regulator of reproductive behaviors, including parturition in mammals. Arg-vasopressin (AVP) is a nonapeptide homologous to Arg-vasotocin (AVT) in teleosts that has comparable affinity for the OT receptor. In the present study,

The Neural Distribution of Vasotocin, Oxytocin, Dopamine, and Serotonin in Two Australian Skinks With Contrasting Social Lives

open access: yesJournal of Comparative Neurology, Volume 534, Issue 7, July 2026.
1. We investigated two skink species differing primarily in social ecology. 2. Using immunohistochemistry, we investigated the distribution of four neurotransmitters known to play a role in vertebrate social behavior. 3. We generally found these transmitters in more brain regions in the family‐living species.

Nonapeptides Arginine Vasotocin and Isotocin in Fishes: Advantage of Bioactive Molecules Measurement

open access: yesFrontiers in Marine Science, 2020
The aim of this article is to share with fish physiologists and behaviorists our thoughts and hints regarding the involvement of nonapeptides in various physiological and behavioral processes in fishes and the advantage of measurements of bioavailable ...

Nonapeptides and the Evolution of Social Group Sizes in Birds

open access: yesFrontiers in Neuroanatomy, 2011
Species-typical patterns of grouping have profound impacts on many aspects of physiology and behavior. However, prior to our recent studies in estrildid finches, neural mechanisms that titrate species-typical group size preferences, independent of other ...

Oxytocin‐ und Vasopressin‐Photosonden zur Entschlüsselung der Neuropeptid‐Signalgebung mit hoher räumlicher und zeitlicher Präzision

open access: yesAngewandte Chemie, Volume 138, Issue 22, 25 May 2026.
Neue biokompatible Oxytocin‐ und Vasopressin‐Photosonden mit modernsten Photocages. Diese Photosonden sind inaktiv und können mit spezifischen Lichtwellen entschützt werden, was eine Rezeptoraktivierung mit hoher zeitlicher und räumlicher Kontrolle ermöglicht.

Behavioral Relevance of Species-Specific Vasotocin Anatomy in Gregarious Finches

open access: yesFrontiers in Neuroscience, 2013
Despite substantial species differences in the vasotocin/vasopressin (VT/VP) circuitry of the medial bed nucleus of the stria terminalis (BSTm) and lateral septum (LS; a primary projection target of BSTm VT/VP cells), functional consequences of this ...

Brain nonapeptide levels are related to social status and affiliative behaviour in a cooperatively breeding cichlid fish [PDF]

open access: yesRoyal Society Open Science, 2015
The mammalian nonapeptide hormones, vasopressin and oxytocin, are known to be potent regulators of social behaviour. Teleost fishes possess vasopressin and oxytocin homologues known as arginine vasotocin (AVT) and isotocin (IT), respectively. The role of

Photocaged Oxytocin and Vasopressin Probes to Decipher Neuropeptide Signalling With High Spatiotemporal Resolution

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 22, 25 May 2026.
Novel and biocompatible photoactivatable oxytocin and vasopressin probes, utilising state‐of‐the‐art photocages, remain inactive in the dark. Light exposure facilitates rapid spatiotemporal receptor activation and phospholipase C (PLC)‐mediated downstream signalling. Figure created in https://BioRender.com.

Identifying context-specific gene profiles of social, reproductive and mate preference behavior in a fish species with female mate choice

open access: yesFrontiers in Neuroscience, 2012
Sensory and social inputs interact with underlying gene suites to coordinate social behavior. Here we use a naturally complex system in sexual selection studies, the swordtail, to explore how genes associated with mate preference, receptivity, and ...
