Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)

Integrative Zoology, EarlyView.
Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

Investigating Development and Defense Systems in Early Reproductive Stages of Male and Female Gonads in Black Scorpionfish Scorpaena porcus (Linnaeus, 1758)

Biology
One of the most crucial biological indicators in tracking long-term variations in the reproductive cycle is sexual development. Scorpaena porcus (Linnaeus, 1758), commonly known as the black scorpionfish, is a small teleost from the family Scorpaenidae ...

Inhibin βB Mediates Oligotrophic Adaptation via Regulating Muscle Satellite Cell Proliferation and Differentiation in Schizopygopsis younghusbandi

Integrative Zoology, EarlyView.
① Nutrient deficiency upregulates inhibin βB, activating SMAD signaling to promote p21. Increased p21 inhibits mcm2/mcm4/mcm5 and cyclin E2, inducing G1‐phase arrest, slowing growth, and reducing energy consumption. ② Inhibin βB also upregulates pdgf‐c, which induces α‐SMA, leading to muscle satellite cell fibrosis.

Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

Integrative Zoology, EarlyView.
Across selected bullfrog farms in major Chinese production regions, 106 intestinal ARG subtypes were detected, with tetracycline and sulfonamide resistance genes predominating and clear farm‐level variation. High‐risk ARGs, including ermB, floR, and qnrA, were associated with heavy metals, MGEs, and opportunistic pathogens. These findings highlight the

Ectopic taste receptors in animal physiology: evolutionary conservation and functional diversification

Frontiers in Cell and Developmental Biology
Taste perception is crucial for animals to assess food’s nutritional value while avoiding toxic substances. Recent decades have unveiled the presence of taste receptors beyond the oral cavity, expressed in diverse non-gustatory tissues including ...

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

Embracing uncertainty in time: A Bayesian dynamic mixing model for isotopic diet estimation

Methods in Ecology and Evolution, EarlyView.
Abstract Isotopic mixing models are powerful tools in ecology for estimating diets. Since their initial formulation, these models have evolved into two distinct branches: Bayesian mixing models and dynamic mixing models. Bayesian mixing models significantly improve uncertainty management but remain static assuming a stable state.

Sex- and stage-dependent expression of gonadal soma-derived factor paralogues reveals functional and evolutionary divergence in European sea bass (Dicentrarchus labrax)

Frontiers in Endocrinology
IntroductionThe gonadal soma-derived factor (Gsdf) is a member of the Transforming Growth Factor-β (TGF-β) superfamily, with key roles in teleost reproduction, particularly in males.

MSA teleost PXR sequences, based on LBD

, 2018
Based on their ligand binding domains, sequences identified in the bioinformatic searches of 76 teleost genome assemblies, using zebrafish, medaka, and tetraodon Pxr as query, were aligned with annotated or cloned teleost Pxr (Nr1i1), Vdr (Nr1i2 ...
