Through the Sands of Time: Evolutionary History and Systematics of the Awl‐Headed Snakes (Colubridae: Lytorhynchus) in the Saharo‐Sindian Region

open access: yesZoologica Scripta, EarlyView.
ABSTRACT The psammophilous colubrid genus Lytorhynchus is widely distributed in the deserts of the Saharo‐Sindian region and adjacent areas. The taxonomy of the genus and the number of recognised species have remained unstable since the last taxonomic revision in 1970, with differing views on the taxonomic status of L. gaddi and L. kennedyi.

A Critique of the Taxonomy of Subtribe Celmisiinae (Asteraceae: Tribe Astereae) With New Combinations in Pleurophyllum Hook.f. sens. lat. and Shawia hesperia (Heenan & Molloy) Heenan comb. nov.

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 4, December 2026.
This review is of the recently revised circumscriptions of the Pleurophyllum Hook.f. group and Shawia J.R.Forst. & G.Forst. of subtribe Celmisiinae, both centred in New Zealand. Recognition of Shawia is supported, and phylogenetic data recover seven well‐supported subclades treated as infrageneric sections.

Subclade B3 and D3 enterovirus D68 among children with severe community-acquired pneumonia in China, 2021 to 2024

open access: yesScientific Reports
Enterovirus D68 (EV-D68) is an emerging pathogen that causes severe respiratory infections in children worldwide and has the potential to re-outbreak. The aim of this study was to assess EV-D68 detection and genetic variability in pediatric patients with

Morphometrics and Mitochondrial (COI‐Based) Molecular Barcoding of Diptychus maculatus Steindachner, 1866, Snow Trout from the Trans‐Himalayan Region of Ladakh, India

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT The present study integrates morphometric analysis, length–weight relationship (LWR), condition factor, and mitochondrial COI‐based molecular barcoding to elucidate the biological characteristics of Diptychus maculatus and confirm species identity, respectively, from the Trans‐Himalayan region of Ladakh, India.

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2790-2837, October 2026.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Emergence of a carbapenem-resistant atypical uropathogenic Escherichia coli clone as an increasing cause of urinary tract infection

open access: yesNature Communications
Carbapenem-resistant Enterobacterales pose a critical global health threat, exemplified by increasing resistance of uropathogenic E. coli (UPEC) that cause urinary tract infections (UTIs).

Characterisation of Typical Enteropathogenic Escherichia coli (tEPEC) and bfpA Genes From Five Bat Species Reveals Australian Pteropus Spp. Are Natural tEPEC Hosts

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
This study revealed that Australia's five Pteropus bat species are all natural hosts of typical Enteropathogenic Escherichia coli (tEPEC)—historically considered a human‐specific pathogen. Across the five Pteropus spp., tEPEC prevalence ranged between 14.2% and 37.0%, with 18 bat‐specific tEPEC strain types and 24 bat‐specific bfpA allele types ...

Target Capture of Ancient Shell DNA Enables Phylogenetic Reconstruction of Deep‐Sea Molluscs

open access: yesMolecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Target capture is widely used to enrich endogenous DNA from calcium phosphate skeletal material in vertebrates, but its performance on calcium carbonate hard parts widely produced by invertebrates remains poorly understood. Here, we compared DNA recovery from four fresh and 12 ancient (eight radiocarbon‐dated to 1671–1135 years old before ...

Domestication‐associated reduction of methyl salicylate in tomato root and its significance for resistance to root‐knot nematode

open access: yesNew Phytologist, Volume 252, Issue 1, Page 414-426, October 2026.
Root volatile profiling reveals domestication‐associated variation in methyl salicylate (MeSA) accumulation in tomato. Summary Methyl salicylate (MeSA) plays diverse roles in the aerial parts of plants. By contrast, its biosynthesis and function in roots remain poorly understood.
