Arginine vasotocin regulates social ascent in the African cichlid fish Astatotilapia burtoni.
Neuropeptides modulate many aspects of behavior and physiology in a broad range of animals. Arginine vasotocin (AVT) is implicated in mediating social behavior in teleost fish, although its specific role varies between species, sexes, life stages, and social context. To investigate whether the effects of AVT on behavior depend on social context, we used the African cichlid fish Astatotilapia bu...
متن کاملSomatostatin regulates aggressive behavior in an African cichlid fish.
Animals respond to environmental and social change with plasticity in the neural substrates underlying particular behavioral states. In the African cichlid fish Astatotilapia burtoni, social dominance status in males is accompanied by reduced somatic growth rate as well as increased somatostatin neuron size in the preoptic area. Although somatostatin is commonly studied within the context of gr...
متن کاملAromatase regulates aggression in the African cichlid fish Astatotilapia burtoni.
The roles of estrogen and androgens in male social behavior are well studied, but little is known about how these hormones contribute to behavior in a social hierarchy. Here we test the role of aromatase, the enzyme that converts testosterone into estradiol, in mediating aggression and reproductive behavior in male Astatotilapia burtoni, an African cichlid fish that displays remarkable plastici...
متن کاملDistribution of nonapeptide systems in the forebrain of an African cichlid fish, Astatotilapia burtoni.
Nonapeptides and their receptors have important functions in mediating social behavior across vertebrates. Where these nonapeptides are synthesized in the brain has been studied extensively in most vertebrate lineages, yet we know relatively little about the neural distribution of nonapeptide receptors outside of mammals. As nonapeptides play influential roles in behavioral regulation in all ve...
متن کاملSerotonergic Modulation of Startle - Escape Plasticity in an African 1 Cichlid Fish : A Single - Cell Molecular and Physiological Analysis of a Vital 2 Neural Circuit
24 Social life affects brain function at all levels, including gene expression, 25 neurochemical balance, and neural circuits. We have previously shown that in 26 the cichlid fish Astatotilapia burtoni brightly colored, socially dominant (DOM) 27 males face a trade off between reproductive opportunities and increased 28 predation risk. When compared with camouflaged subordinate (SUB) males, 29 ...
