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

Developmental Dynamics, EarlyView.
Abstract Background Dentitions 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.

Novel Endogenous Probiotics Enhance Host Intestinal Health, Liver Immune Capacity, Meat Nutritional Composition, and Aquatic Environmental Quality in Pelodiscus sinensis

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Currently, the in‐depth research and practical application of probiotics in the green and healthy breeding of Chinese soft‐shelled turtles (Pelodiscus sinensis) remain limited. This study conducted a 30‐day feeding trial with turtles of an initial weight of 528.95 ± 2.96 g. The aim was to evaluate the effects of three endogenous probiotics—Enterococcus

A Terrestrial Thermometer Using Carbonate Clumped Isotopes From Gar Scales

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 2, February 2025.
Abstract We present a new clumped isotope calibration relating temperature to the Δ47 composition of the bioapatite scales of gar fish (Lepisosteidae family). Modern gars live at <∼3 m depth in rivers and lakes, are non‐migratory, and their scales grow continuously over their lifespan (∼8–14 years).
