Dominance hierarchies and social status ascent opportunity: Anticipatory behavioral and physiological adjustments in a Neotropical cichlid fish
(Pergamon-Elsevier Science Ltd, 2012-07)
In this work we characterized the social hierarchy of non-reproductive individuals of Cichlasoma dimerus (Heckel, 1840), independently for both sexes, and its relationship to the opportunity for social status ascent. Female ...

Stress responses of the fish Nile tilapia subjected to electroshock and social stressors
(Associação Brasileira de Divulgação Científica (ABRADIC), 2006-12-01)
Plasma cortisol and glucose levels were measured in 36 adult Nile tilapia males, Oreochromis niloticus (standard length, mean ± SD, 14.38 ± 1.31 cm), subjected to electroshock and social stressors. Pre-stressor levels were ...

Social Stability Related to Sex Group Composition in the Cichlid Nile Tilapia
(2011)
Aquaculture practices usually put the Nile tilapia in an artificial social environment, which males predominate due to their faster growth desirable for aquaculture purposes. Such a situation can increase male-male fighting ...
Relação entre o sistema imune e o comportamento em zebrafish
(Universidade Federal de Santa MariaBrasilFarmacologiaUFSMPrograma de Pós-Graduação em FarmacologiaCentro de Ciências da Saúde, 2020-03-06)
The interaction between immune system and behavior has already been observed in several studies using mammals as animal model. On the other hand, this relationship has not yet been clearly demonstrated in other animal ...
Bayesian analysis improves experimental studies about temporal patterning of aggression in fish
(2017-12-01)
This study aims to describe a Bayesian Hierarchical Linear Model (HLM) approach for longitudinal designs in fish's experimental aggressive behavior studies as an alternative to classical methods In particular, we discuss ...
