The objective was to characterize female germ cell renewal during the annual reproductive cycle in two species of ostariophysian fish with distinct reproductive strategies: a siluriform, Pimelodus maculatus, in which oocyte ...

The objective was to evaluate the effect of the interaction of diet density in the rearing phasexdiet density in the reproductive phase on carcass composition, pregnancy rate, and litter performance of primiparous rabbit ...

Artibeus lituratus is one of the most recognized bat species in the neotropics, probably due to its high abundance in urban areas. Despite its wide distribution, the morphology and physiology of its reproductive organs ...

Individuals of the same species may present different reproductive tactics depending on the environment in which they develop and mature. The present study aimed to define the gonadal development phases of males and females ...

Morphofunctional gonadal alterations constitute an annual cycle in birds during which four phases can be distinguished in the testes based on histological modifications in the seminiferous epithelium, called quiescence, ...

Amphibian reproductive modes (RMs) have been extensively described and applied to amphibian biology stud-ies. However, due to new behavioural observations and past system inconsistencies we found it necessary to review the ...
