A Method for Quantifying, Visualising, and Analysing Gastropod Shell Form. [PDF]

open access: yesPLoS ONE, 2016
Quantitative analysis of organismal form is an important component for almost every branch of biology. Although generally considered an easily-measurable structure, the quantification of gastropod shell form is still a challenge because many shells lack ...

Conkazal-M1 from the MKAVA family of conotoxins: A dual-function protease inhibitor and neuroactive peptide. [PDF]

open access: yesProtein Sci
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

Proteomic analysis of trochophore and veliger larvae development in the small abalone Haliotis diversicolor [PDF]

open access: yesBMC Genomics, 2017
Background Haliotis diversicolor is commercially important species. The trochophore and veliger are distinct larval stages in gastropod development. Their development involves complex morphological and physiological changes.

Evidence that gastropod torsion is driven by asymmetric cell proliferation activated by TGF-beta signalling. [PDF]

open access: yesBiol Lett, 2011
Gastropods are characterized by their asymmetric bodyplan, which develops through a unique ontogenetic process called ‘torsion’. Despite several intensive studies, the driving force of torsion remains to be determined. Although torsion was traditionally believed to be driven by contraction of the retractor muscle connecting the foot and ...

GASTROPOD TORSION: A TEST OF GARSTANG'S HYPOTHESIS

open access: yesThe Biological Bulletin, 1985
Torsion occurs in gastropod molluscs as a 180° twisting of the shell and viscera relative to the head and foot of the veliger larva. Garstang (1928, 1929) proposed, and it has since become widely accepted, that torsion functions as a larval defense by allowing veligers to first pull the head into the shell, then sealing the aperture with the foot and ...

New partial skeleton of Homo habilis from the upper Burgi Member, Koobi Fora Formation, Ileret, Kenya

open access: yesThe Anatomical Record, Volume 309, Issue 3, Page 485-545, March 2026.
Abstract KNM‐ER 64061 is a partial skeleton from the upper Burgi Member of the Koobi Fora Formation (2.02–2.06 Ma) associated taphonomically and geochemically with a nearly complete mandibular dentition (KNM‐ER 64060) attributed to Homo habilis.

Primary Productivity and Habitat Depth Shape Developmental Mode in European Marine Gastropods

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Thorson's rule suggests that marine gastropods in colder, high‐latitude regions tend to have non‐pelagic (non‐drifting) larval development. However, this study on 94 European gastropod species found that the rule disappears when examined at finer spatial scales, with temperature and phylogeny having little influence.

Reconstructing human‐induced geomorphic changes through historical maps and multitemporal remote sensing data in the Cancano–San Giacomo di Fraele reservoirs (Central Alps, Italy)

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Reconstructing ~200 years of landscape change at the Cancano–San Giacomo hydroelectric system (Central Alps), we integrate historical cartography, archival photographs, multitemporal aerial/satellite imagery and field validation to map pre‐ and post‐impoundment landforms.

Facies mosaic distribution and stratigraphic disorder of a mixed carbonate–siliciclastic tidal succession

open access: yesSedimentology, Volume 73, Issue 1, Page 40-82, January 2026.
ABSTRACT Complex stratigraphic arrangements may be generated through lateral facies transitions from the strata of aeolian depositional systems into bordering peritidal deposits. In such scenarios, sedimentary architectural complexity and associated facies heterogeneities are governed by the interplay between autogenic processes inherent to tidal ...

Biological and Biologically Inspired Functional Nanostructures: Insights into Structural, Optical, Thermal, and Sensing Applications

open access: yesAdvanced Materials, Volume 37, Issue 51, December 23, 2025.
Biological and biologically‐inspired functional nanostructures with structural, thermal, optical, and sensing applications are reviewed. The role of nanoscale features in biological materials on performance is described, and their blueprints are used for bio‐inspired nanomaterials, synthesized using advanced techniques (i.e., photolithography, bio ...
