Integrated use of biomarkers to evaluate the reproductive physiology of Astyanax fasciatus and Hoplias malabaricus males (Teleostei: Characiformes) in polluted reservoirs
(Elsevier B.V., 2021-01-15)
The reproductive physiology of fish can be changed by the presence of pollutants in the water, which act as endocrine disrupting compounds (EDC). We evaluated the impacts of water contaminants in polluted reservoirs acting ...

Presence of 11-ketotestosterone in pre-differentiated male gonads of Odontesthes bonariensis
(Springer, 2013-02)
The involvement of androgens during sex differentiation period was investigated in the pejerrey Odontesthes bonariensis, by classic biochemical studies and gonadal histology. We studied in particular whether the enzyme ...
Effects of selection of morphological traits on aggression and physiology in Pterophyllum scalare
(Universidade Estadual Paulista (Unesp), 2016-08-31)
Domesticação animal tipicamente seleciona loci gênicos que controlam um traço de interesse humano, podendo levar à seleção indireta de outros traços devido aos efeitos pleiotrópicos. Aqui, nós testamos como a seleção ...
Can estrogens be considered as key elements of the challenge hypothesis?The case of intrasexual aggression in a cichlid fish
(Pergamon-Elsevier Science Ltd, 2018-10)
Territorial aggression has been widely studied in males and it has been historically suggested that androgens are key mediators of this behavior. However, more recent evidence suggests that it is the aromatization to ...
Changes in plasma steroid hormones and gonadal histology associated with sexual maturation in wild southern hake (Merluccius australis)
(Pontificia Universidad Católica de Valparaíso, 2017)
Estrogen-induced inhibition of spermatogenesis in zebrafish is largely reversed by androgen
(Bioscientifica Ltd, 2018-05-01)
The hormonal regulation of spermatogenesis involves both gonadotropins and steroid hormones. Long-term in vivo exposure of adult zebrafish to estrogen impaired spermatogenesis associated with an androgen insufficiency, ...
