In vivo storage of oocytes leads to lower survival, increased abnormalities and may affect the ploidy status in the yellowtail tetra Astyanax altiparanae
(Cambridge Univ Press, 2018-12-01)
In this study we analyzed whether the in vivo storage of oocytes (time after ovulation until fertilization) affects the survival and the ploidy status of the yellowtail tetra Astyanax altiparanae. Fish were induced to spawn ...

Testing Wallace's intuition: water type, reproductive isolation and divergence in an Amazonian fish
(Wiley-Blackwell, 2018-06-01)
Alfred Russel Wallace proposed classifying Amazon rivers based on their colour and clarity: white, black and clear water. Wallace also proposed that black waters could mediate diversification and yield distinct fish species. ...
