Star‐Like Radiation of Leucostigma candidescens Populations (Gastropoda: Clausiliidae) and Repeated Changes in Chirality

open access: yesZoologica Scripta, Volume 55, Issue 1, Page 62-73, January 2026.
ABSTRACT Leucostigma candidescens is a rock‐dwelling door snail species, which is widespread in the central and southern Apennines of Italy. The species has been divided into nine subspecies. Three of them are characterised by a change in the coiling direction, which is usually a rare evolutionary event.

Patterns of Diversity of the Rissoidae (Mollusca: Gastropoda) in the Atlantic and the Mediterranean Region

open access: yesThe Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
The geographical distribution of the Rissoidae in the Atlantic Ocean and Mediterranean Sea was compiled and is up‐to‐date until July 2011. All species were classified according to their mode of larval development (planktotrophic and nonplanktotrophic), and bathymetrical zonation (shallow species—those living between the intertidal and 50 m depth, and ...

Transitional Failure of Carbon Nanotube Systems under a Combination of Tension and Torsion

open access: yesJournal of Nanomaterials, Volume 2012, Issue 1, 2012., 2012
Transitional failure envelopes of single‐ and double‐walled carbon nanotubes under combined tension‐torsion are predicted using classical molecular dynamics simulations. The observations reveal that while the tensile failure load decreases with combined torsion, the torsional buckling moment increases with combined tension.

An aminostratigraphy of the northern Upper Rhine Graben, Germany

open access: yesJournal of Quaternary Science, Volume 40, Issue 7, Page 1147-1175, October 2025.
ABSTRACT The northern Upper Rhine Graben (Germany) contains a complex, quasi‐continuous Quaternary record, but constraining its chronology is challenging. This study presents the first application of amino acid geochronology for this region using Bithynia opercula to establish a relative dating framework.

Repeated colonization of the Northern Limestone Alps from the Southern Limestone Alps by the rock‐dwelling snail species Cochlostoma henricae

open access: yesZoologica Scripta, Volume 53, Issue 5, Page 580-593, September 2024.
Abstract Hausdorf, B., Xu, J., BAMBERGER, S. (2024) Repeated colonization of the Northern Limestone Alps from the Southern Limestone Alps by the rock‐dwelling snail species Cochlostoma henricae—Zoologica Scripta, 00, 000–000. The evolution of biogeographic disjunctions in the Southern and Northern Limestone Alps has been studied only in a few taxa ...

A study of the Nordsieck-type predictor-corrector methods [PDF]

open access: yes, 1971
Predictor-corrector schemes are discussed for the numerical integration of initial value problems by computer. Descloux formulas, which are considered modified Nordsieck formulas are studied because of their desirable stability and truncation properties ...

The 3D time evolution of the dust size distribution in protostellar envelopes

open access: yesAstronomy & Astrophysics
Context. Dust plays a fundamental role during protostellar collapse and disk and planet formation. Recent observations suggest that efficient dust growth can begin early in the protostellar envelopes, potentially even before the formation of the disk ...

Taxonomic revision and dissolution of the genus Monachoides (Gastropoda, Stylommatophora)

open access: yesZoologica Scripta, Volume 53, Issue 4, Page 419-437, July 2024.
Abstract Monachoides is a genus of medium‐sized European land snails in the family Hygromiidae. Systematics of this family was until recently based on traits of the genital system that were shown to be uninformative, resulting in revisions of classifications at the genus and family levels.
