Reproductive biology of the neotropical rattlesnake Crotalus durissus from northeastern Brazil: a test of phylogenetic conservatism of reproductive patterns
(British Herpetol Soc, 2012-04-01)
We studied reproductive patterns in neotropical rattlesnakes (Crotalus durissus) from areas with different climatic conditions. The timing of female reproductive events (vitellogenesis, sperm storage and parturition) was ...

Reproductive disorders in female rats after prenatal exposure to betamethasone
(2017-09-01)
Betamethasone is the drug of choice for antenatal treatment, promoting fetal lung maturation and decreasing mortality. Previous studies in rats reported male programming and alteration in sperm parameters and sexual behavior ...
Gonadal morphology and difference in reproductive development of two isolated populations of Astyanax rivularis (Teleostei, Characidae)
(2021-01-01)
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 ...
Morphological variation of the female reproductive organs of the bat Artibeus lituratus during its different reproductive phases
(2019-08-01)
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 ...
