Journal of Comparative Neurology, Volume 534, Issue 4, April 2026.The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Latin American Journal of Aquatic Research, 2020 Tropical gar ( Atractosteus tropicus ) is currently exploited regionally as food and commercialized in the aquarium trade. Natural populations of A. tropicus may already be negatively affected by anthropogenic alteration of the areas in which it is distributed. However, it is necessary to deepen the knowledge for the optimization of its culture.

Ecology and Evolution, Volume 16, Issue 3, March 2026.This study reveals an unexpectedly simplified, Brachyspira‐dominated gastrointestinal microbiota in pompano dolphinfish from both neritic and deep‐sea habitats of the South China Sea. Environmental DNA and functional analyses suggest these fish may acquire potential pathogens in anthropogenically influenced coastal waters and transport them offshore ...

Coyote Range Expansion in the Human‐Modified Tropics of Mesoamerica
Ecology and Evolution, Volume 16, Issue 3, March 2026.Coyotes have expanded their range into southeastern Mexico, Guatemala, and Belize, increasingly occupying human‐modified landscapes. This expansion is ongoing, with rising detection rates over time and records in both disturbed and forested environments, highlighting a paradox where anthropogenic change enables native carnivore expansion.

Evaluation of microencapsulated diets for tropical gar (Atractosteus tropicus) larviculture
, 2018 Four microencapsulated diets were evaluated with respect to the growth and survival of tropical gar Atractosteus tropicus larvae. The treatments consisted of four experimental diets and one control diet 1) fish meal, 2) a combination of pork and poultry meals, 3) Nannochloropsis gaditana meal, 4) enzyme preparation and the control treatment 5) Artemia ...

Aquaculture Research, 2019 Five experimental diets with different carbohydrates/lipid ratio (CHO:L, 0.75, 1.28, 2.10, 2.52, 4.63) were formulated. Fish were randomly assigned by triplicate (10 fish per tank, 0.50 ± 0.01 g). Growth was registered every 15 days until end of the experiment (45 days).
