Evolutionary modifications of Astyanax larval prey capture (LPC) in a dark environment
《Zoological Research》2023年第4期750-760,共11页Luis Espinasa Ruth Diamant Ehud Vinepinsky Monika Espinasa 
funded by German Sumbre at the Institut de Biologie de l’ENS (IBENS), CNRS, France;Sylvie Rétaux at the Paris-Saclay Institute of Neuroscience, CNRS;University Paris-Saclay, France
Feeding strategies of an organism depend on the multimodal sensory processing that most efficiently integrates available visual,chemosensory,and/or mechanoreceptive cues as part of their environmental adaptation.The b...

Cytogenetic Analysis of Three Species of Astyanax Genus （Pisces, Characidae, Incertae sedis） from Freshwaters of Upper Paraguay Basin, Mato Grosso State, Brazil
《Journal of Life Sciences》2014年第1期51-57,共7页Diones Krinski Carlos Suetoshi Miyazawa 
Cytogenetic studies have shown that the genus Astyanax has extensive karyotypic variability among species and many are the works developed about this group in different river basins in Brazil. The Tangara da Serra ar...
