Chromosome‐Level Genome Assemblies of Two Softshell Turtles with ZZ/ZW Provide Insights into TE‐Driven Recombination Suppression in Sex Chromosomes

open access: yesIntegrative Zoology, EarlyView.
This study presents the first genomic identification and characterization of ZW sex chromosomes in two soft‐shelled turtle species through genome assembly and resequencing. We reveal the structural organization of ZW chromosomes, identifying both pseudoautosomal regions (PARs) and differentiated regions.

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

open access: yesIntegrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

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

open access: yesIntegrative 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

Hybridization With a Non‐Native Congener Threatens the Catalan Chub (Squalius laietanus): Optimization of a DNA‐Based Early Warning Tool

open access: yesIntegrative Zoology, EarlyView.
Hybridization with non‐native congeners threatens endemic freshwater fishes. Using a rapid and cost‐effective nuclear DNA assay, we detected widespread hybridization between the Catalan chub (Squalius laietanus) and the non‐native European chub (Squalius cephalus) across S.

Integrated Multi‐Omics Analysis Reveals the Genetic Basis of Phenotypic Variation in Tibetan Sheep

open access: yesIntegrative Zoology, EarlyView.
SNaPshot‐validated GWAS results demonstrated significant correlations between candidate single nucleotide polymorphisms (SNPs) and body size traits in Tibetan sheep. Concurrently, hematoxylin and eosin staining, alongside muscle fiber analysis, confirmed pronounced morphological differences in muscle tissue between sheep of varying conformation.

Comparisons Between Large‐Scale Genomic Variants and SNPs in Driving Population Divergence and Local Adaptation

open access: yesIntegrative Zoology, EarlyView.
Candidate genes identified from SNPs, indels, and SVs exhibited limited shared genes, suggesting that diverse variant types capture complementary aspects of the adaptive landscape. Our results underscore the importance of incorporating multiple types of genomic variation to achieve a more comprehensive understanding of evolutionary processes.
