The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, Volume 37, Issue 1, Page 317-355, November 2026.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

Zoologica Scripta, Volume 55, Issue 6, Page 830-845, November 2026.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

Discovery of Novel Conotoxin Candidates Using Machine Learning

Toxins, 2018
Cone snails (genus Conus) are venomous marine snails that inject prey with a lethal cocktail of conotoxins, small, secreted, and cysteine-rich peptides.

Measuring Bird Morphology From Field Photographs

Ecology and Evolution, Volume 16, Issue 10, October 2026.
We evaluated a digital photography approach based on the pinhole camera model to estimate bird morphometric traits from single images, testing its accuracy under controlled conditions and across 37 species photographed in the field. Photographic measurements showed strong agreement with museum and database‐derived traits (ρ = 0.82–0.95), with wing and ...

Why do snails have hairs? A Bayesian inference of character evolution [PDF]

, 2005
Background: Costly structures need to represent an adaptive advantage in order to be maintained over evolutionary times. Contrary to many other conspicuous shell ornamentations of gastropods, the haired shells of several Stylommatophoran land snails ...

Efficient oxidative folding of conotoxins and the radiation of venomous cone snails [PDF]

Proceedings of the National Academy of Sciences, 2003
The 500 different species of venomous cone snails (genus Conus ) use small, highly structured peptides (conotoxins) for interacting with prey, predators, and competitors. These peptides are produced by translating mRNA from many genes belonging to only a few gene superfamilies.

Proteo-Transcriptomic Analysis of the Venom Gland of the Cone Snail Cylinder canonicus Reveals the Origin of the Predatory-Evoked Venom

Toxins
Cone snails are carnivorous marine predators that prey on mollusks, worms, or fish. They purposefully inject a highly diversified and peptide-rich venom, which can vary according to the predatory or defensive intended use.

Purification and Characterization of the Pink-Floyd Drillipeptide, a Bioactive Venom Peptide from Clavus davidgilmouri (Gastropoda: Conoidea: Drilliidae)

Toxins, 2020
The cone snails (family Conidae) are the best known and most intensively studied venomous marine gastropods. However, of the total biodiversity of venomous marine mollusks (superfamily Conoidea, >20,000 species), cone snails comprise a minor fraction ...

Schwann Cells in Physical Nerve Injury and Tumor Perineural Invasion: A Functional Overview and Comparison

Cancer Medicine, Volume 15, Issue 9, September 2026.
ABSTRACT The nervous system exhibits remarkable stability, making its repair challenging. Compared to the central nervous system, peripheral nerve injuries demonstrate a greater potential for regeneration. Schwann cells, the unique myelinating glial cells of the peripheral nervous system, possess striking plasticity and support nerve regeneration ...
