Journal ArticleDOI
The Bidder's organ of the toad Rhinella arenarum (Amphibia, Anura). Presence of steroidogenic enzymes.
María Florencia Scaia,Eleonora Regueira,Alina Grisel Sassone,María Clara Volonteri,Nora R. Ceballos +4 more
TL;DR: It is found that BOs weight was significantly lower in males during the pre-reproductive period and that there is no significant correlation between the weights of BO and the adjacent testis, which confirm the steroidogenic capacity of the BO in adult males of R. arenarum.
Journal ArticleDOI
Can estrogens be considered as key elements of the challenge hypothesis? The case of intrasexual aggression in a cichlid fish
María Florencia Scaia,María Florencia Scaia,Leonel Morandini,CristobalAlejandro Noguera,Vance L. Trudeau,Gustavo M. Somoza,Matías Pandolfi,Matías Pandolfi +7 more
TL;DR: It is suggested that female aggression is associated with initial levels of estradiol-17β, and that the challenge hypothesis, originally defined for androgens, could also be extended to estrogens.
Journal ArticleDOI
Sexual Dimorphism in Aggression: Sex-Specific Fighting Strategies Across Species.
TL;DR: Aggressive behavior is thought to have evolved as a strategy for gaining access to resources such as territory, food, and potential mates in both invertebrate and vertebrate species as discussed by the authors.
Journal ArticleDOI
Fighting cichlids: Dynamic of intrasexual aggression in dyadic agonistic encounters.
María Florencia Scaia,María Florencia Scaia,Leonel Morandini,Cristobal Alejandro Noguera,Martín Roberto Ramallo,Gustavo M. Somoza,Matías Pandolfi,Matías Pandolfi +7 more
TL;DR: Results suggest that C. dimerus females are as aggressive as males and that they have similar motivation towards territorial aggression, emphasizing the need of deepening the study of aggression in females and not only in males.
Journal ArticleDOI
Apoptosis, proliferation and presence of estradiol receptors in the testes and Bidder's organ of the toad Rhinella arenarum (Amphibia, Anura).
TL;DR: It is suggested that cysts that do not form spermatozoa are removed from testes by apoptosis and that estrogens regulate both spermatogenesis and oogenesis in adult males of R. arenarum.
