Cross amplification of microsatellite loci developed for Atractosteus spatula in Atractosteus tropicus [PDF]

open access: yesRevista Mexicana de Biodiversidad, 2013
AbstractDue to recent population declines in tropical gar (Atractosteus tropicus), a greater understanding of its population structure is needed. A key step in gaining this understanding is the development of microsatellite loci for use in this species. For this purpose, 33 microsatellite loci from alligator gar (A.

Sex-specific differences in transcriptome profiles of brain and muscle tissue of the tropical gar [PDF]

open access: yesBMC Genomics, 2017
Background The tropical gar (Atractosteus tropicus) is the southernmost species of the seven extant species of gar fishes in the world. In Mexico and Central America, the species is an important food source due to its nutritional quality and low price ...

Predation by Atractosteus tropicus on Bufo marinus and its possible affect on population in a lowland tropical wet rainforest [PDF]

open access: yes, 2022
Fish predation can affect amphibian populations. Most examples report invasive fish species and their negative effect on specific amphibians. Here we provide an occurrence of natural fish predation by the tropical gar Atractosteus tropicus on the cane toad Bufo marinus. We observed physical damage caused by A. tropicus attacking B. marinus.

Effects of Dietary Sodium Propionate on Growth, Digestive Enzyme Activity, and Expression of Immune System Genes in Juveniles of Tropical Gar (Atractosteus tropicus)

open access: yesAquaculture Journal, 2023
We determined the effects of sodium propionate (SP) added to the diets of Atractosteus tropicus juveniles with respect to the growth, survival, digestive enzyme activity, and expression of genes that are associated with the immune system. Five treatments

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics
AbstractBackgroundDentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.
