Tracing Ancient Migration Routes: Did Gloydius Pitvipers Disperse Across Paleo‐Tibet Through Temperate and Subtropical Corridors?

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We investigated the evolutionary and biogeographic history of Himalayan and Hindu Kush Gloydius pitvipers by integrating time‐calibrated phylogenetic analyses with paleoclimatic reconstructions and species distribution modeling. Our results suggest an early Miocene origin in East and Southeast Asia, followed by westward dispersal across Paleo‐Tibet via

Genomic dissection of the clonal background and global dissemination of hypervirulent Klebsiella pneumoniae CG23-KL57 lineage

open access: yesNature Communications
The emergence of multidrug-resistant and hypervirulent Klebsiella pneumoniae represents a growing threat to global public health. Here we investigate the genomic epidemiology and evolutionary dynamics of emerging K.

Global‐Scale Patterns of Host Transitions Suggest Contrasting Levels of Specialization Within Rhizoctonia solani

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We combined a global rDNA‐ITS dataset with TEF‐1α sequences and newly sequenced isolates to examine phylogenetic signal, host associations, and population structure in the soil‐borne pathogen Rhizoctonia solani. Most anastomosis groups formed well‐supported clades, and host‐associated patterns corresponded more strongly with genetic structure than ...

De Novo Assembly and Comparative Analysis of the Complete Mitochondrial Genome of Mesenchytraeus (Annelida, Enchytraeidae)

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This present the first mitochondrial genome dataset for 13 Mesenchytraeus species from the Changbai Mountain glacial refugium. Beyond characterizing standard genomic features, we perform comparative analyses of gene order, nucleotide composition, codon usage, and control region structure.

Evolution of the α‐Glucosidase Gene Family in Apoidea

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study traces the origin of the α‐glucosidase gene family in bees back to approximately 140 million years ago, revealing that its evolutionary history closely aligns with the rise of angiosperms and coevolution. Furthermore, by identifying the core members Hbg1–3 and 28 key functional sites driven by positive selection, the study systematically ...

Recurrent Body Shape Patterns in Cave‐ and Surface‐Dwelling Trichomycterid Catfishes

open access: yesJournal of Morphology, Volume 287, Issue 9, September 2026.
Multivariate shape analyses reveal that body shape consistently differs between cave‐ and surface‐dwelling trichomycterids in northeastern Colombia, with cave species exhibiting fusiform bodies while surface species showed deeper shapes consistently in different clades.

Genomic Epidemiology and Clinical Characteristics of Mpox Lineage C.1 Outbreak in Thailand, 2023–2024

open access: yesJournal of Medical Virology, Volume 98, Issue 9, September 2026.
ABSTRACT Since 2022, human monkeypox virus (hMPXV) has emerged in non‐endemic regions, including Thailand. However, the genomic dynamics and clinical correlates of local transmission remain incompletely defined. Whole‐genome sequencing was performed on hMPXV from 16 patients in Thailand (2023–2024) using targeted amplicon NGS.
