Sexual selection and social hierarchy in fishes.
(2009-01-01)
Sexual selection is a crucial element to understand behavioral evolution. Teleost fish have been considered as good models for research on sexual selection in the last decades due to their variety of sexual behavior. Female ...
Daily changes in the electric behavior of weakly electric fish naturally persist in constant darkness and are socially synchronized
(Company of Biologists Ltd, 2018)
Daily rhythms allow anticipation of changes and allocation of energy to better cope with predictable events. Rhythms in behavior result from a complex combination of physiological processes timed by the nervous system and ...
AGONISTIC PROFILE AND METABOLISM IN ALEVINS OF THE NILE TILAPIA
(Elsevier B.V., 1995-01-01)
Metabolic differences derived from social stress usually show data with high variance that may hinder the finding of important differences. Since such high variance may be caused by agonistic variability occurring during ...

Ventilatory frequency of Nile tilapia subjected to different stressors
(2006-12-12)
Ventilatory frequency (VF) was investigated in the fish Nile tilapia, Oreochromis niloticus, subjected to confinement, electroshock or social stressor. Fish were allowed to acclimatize to tank conditions for 10 days (1 ...

AGONISTIC PROFILE AND METABOLISM IN ALEVINS OF THE NILE TILAPIA
(Elsevier B.V., 2014)
The interrenal gland in males of the cichlid fish Cichlasoma dimerus: Relationship with stress and the establishment of social hierarchies
(Elsevier Inc, 2013-10)
In teleosts, cortisol is the primary glucocorticoid secreted by the steroidogenic cells of the interrenal gland and an increase in its plasma concentration is a frequent indicator of stress. Cortisol has been postulated ...

Preoptic area activation and vasotocin involvement in the reproductive behavior of a weakly pulse-type electric fish, Brachyhypopomus gauderio
(Frontiers Media, 2019)
Social behavior exhibits a wide diversity among vertebrates though it is controlled by a conserved neural network, the social behavior network (SBN). The activity of the SBN is shaped by hypothalamic nonapeptides of the ...
