Is rainfall seasonality important for reproductve strategies in viviparous neotropical pit vipers? A case study with Bothrops leucurus from the Brazilian Atlantc Forest
(2014-01-01)
Two populatons of the Neotropical lancehead Bothrops leucurus were studied in two locatons in Brazil (Espírito Santo, ES, and Bahia, BA) with different rainfall seasonality paterns. The timing of reproducton was very similar ...

(British Herpetol Soc, 2014-04-01)
Two populations of the Neotropical lancehead Bothrops leucurus were studied in two locations in Brazil (Espirito Santo, ES, and Bahia, BA) with different rainfall seasonality patterns. The timing of reproduction was very ...

Unique Derived Features in Spermiogenesis and Sperm Morphology Supporting a Close Relationship between the Species of Hollandichthys and Rachoviscus (Characiformes: Characidae)
(Amer Soc Ichthyologists & Herpetologists, 2012-12-18)
Hollandichthys and Rachoviscus are endemic to the Atlantic coastal drainages of Brazil and have been historically hypothesized as related to different genera and even subfamilies of the Characidae. We describe the testis ...

Ciclo reprodutivo de Philodryas patagoniensis (Serpentes: Dipsadidae) no Sul do Brasil
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2015-12-07)
Tropical snakes present a greater diversity of reproductive patterns influenced by intrinsic
factors and environmental conditions. Reproductive cycles may be more plastic in tropical areas
due to the climatic complexity. ...
Changes in sperm function and structure after freezing in domestic cat spermatozoa
(WILEY, 2018)
Sperm cryopreservation allows for a long-term storage of genetic. However, changes due to factors as cold shock, osmotic and oxidative stress cause reduction in viability and fertilising ability of frozen/thawed spermatozoa. ...
