Larval Development in Tropical Gar (Atractosteus tropicus) Is Dependent on the Embryonic Thermal Regime: Ecological Implications under a Climate Change Context

Fishes, 2022
In ectotherm species, environmental temperature plays a key role in development, growth, and survival. Thus, determining how temperature affects fish populations is of utmost importance to accurately predict the risk of climate change over fisheries and ...

Inclusion of Mannan-Oligosaccharides in Diets for Tropical Gar Atractosteus tropicus Larvae: Effects on Growth, Digestive Enzymes, and Expression of Intestinal Barrier Genes

Fishes, 2022
Mannan-oligosaccharides (MOS) are non-digestible carbohydrates, and their use in aquaculture as prebiotics is well documented. The objective of this work was to test whether MOS supplemented in the diet of A.

Effects of Dietary β‐Glucan on Growth Performance, Haematobiochemical Responses, and Stress‐Related Gene Expression in Stinging Catfish (Heteropneustes fossilis)

Aquaculture, Fish and Fisheries, Volume 6, Issue 6, December 2026.
ABSTRACT The present study evaluated the consequences of dietary β‐glucan on growth, haematobiochemical parameters, and stress‐related gene expression in stinging catfish, Heteropneustes fossilis. A basal diet was supplemented with 0%, 0.05%, 0.1%, and 0.5% yeast β‐glucan and administered to fish at 7%–4% of body weight per day for 100 days.

Early evolution of the gular musculature and its innervation in ray‐finned fishes

The Anatomical Record, Volume 309, Issue 12, Page 3625-3648, December 2026.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Survival and Behavior of Amphibians in a Seasonally Flooded Tropical Forest

Biotropica, Volume 58, Issue 4, July 2026.
How do tropical amphibians survive seasonal flooding? A three‐year capture–mark–recapture study in Costa Rica revealed species‐specific responses to flood events, with flooding reducing apparent survival in some species while others persisted through behavioral adaptations and use of arboreal refugia.
