Loss, persistence and reversal of phenotypic traits

Biological Reviews, Volume 101, Issue 5, Page 2119-2133, October 2026.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Gut Microbiome Diversity, Functional Potential, and Ecological Relevance of Hottentotta tamulus

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Long‐read 16S sequencing uncovers the gut microbiome of H. tamulus. A highly conserved and low‐diversity bacterial community dominates the gut fauna. Bacillus and Mycoplasma lineages emerge as predominant candidate endosymbionts. Exploratory profiles reveal potential sex‐specific trends in microbial abundance.

Spotlight on the Nucleotide: Solid‐State NMR for the Investigation of ATP Hydrolysis in the ATPase SmsC

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Nucleotide‐detected solid‐state NMR has been applied to probe nucleotide conformations and dynamics during ATP hydrolysis using the dimeric P‐loop ATPase SmsC as a model protein. The different stages of ATP hydrolysis have been mimicked by ATP analogues for which different degrees of conformational heterogeneity have been observed. ABSTRACT Solid‐state

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, Volume 309, Issue 9, Page 2286-2297, September 2026.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Computational Studies of Snake Venom Toxins

Toxins, 2017
Most snake venom toxins are proteins, and participate to envenomation through a diverse array of bioactivities, such as bleeding, inflammation, and pain, cytotoxic, cardiotoxic or neurotoxic effects.

Tolerating the Anthropocene: Squamate Life History Shapes Patterns of Presence in Human Modified Landscapes

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
We found that many squamates exhibit moderate tolerance of human modification, with wider ranging, larger bodied, faster reproducing species showing the highest tolerance. Intolerance to modification was linked to extinction risk across squamates, supporting the idea that human activity is a primary driver of reptile declines.

Distinct regulatory networks control toxin gene expression in elapid and viperid snakes

BMC Genomics
Background Venom systems are ideal models to study genetic regulatory mechanisms that underpin evolutionary novelty. Snake venom glands are thought to share a common origin, but there are major distinctions between venom toxins from the medically ...

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...
