THE WORLD ACCORDING TO GARS: THE MOLECULAR SYSTEMATICS AND COMPARATIVE PHYLOGEOGRAPHY OF LIVING GARS (ACTINOPTERYGII: LEPISOSTEIDAE)

, 2011
There are seven living species of gars in two genera (Lepisosteiformes: Actinopterygii). In my first chapter, I estimate phylogenetic relationships among six of them using DNA data generated from four complete mitochondrial loci (cytb, CR, 12S, and 16S)

Permanent germinal epithelium and reproductive cycle of Atractosteus tropicus (Lepisosteiformes: Lepisosteidae) males, Tabasco, Mexico.

Revista de biologia tropical, 2016
A. tropicus tiene un papel ecológico importante, como regulador de otras poblaciones de peces, en los cuerpos de agua de México, pero sus poblaciones silvestres se reducen. Una alternativa de conservación es el cultivo, el cual requiere caracterizar el ciclo reproductivo por medio del estudio de estructuras germinales y somáticas de los testículos ...
