Phylogeny and Species Delimitation in the Land Snail Genus Chilostoma (Gastropoda: Helicidae) and East–West Alpine Disjunctions

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Chilostoma includes large, mostly rock‐dwelling snail species, widespread in the European Alps and the Apennines in Italy. We analysed the phylogenetic relationships and the species delimitation of the Chilostoma (Chilostoma) species based on genomic ddRAD loci. The Chilostoma (Chilostoma) taxa form three sister pairs. Chilostoma achates and C.

Pseudo-two-girdles c-axis fabric patterns in a quartz-feldspar mylonite (Costabona granodiorite, Canigo massif) [PDF]

open access: yes, 2012
An example of the relationship that exist between the preferred crystaliografic orientation of quartz grains and the attitude of the mylonite foliation of quartz-feldspar mylonites is described. These rocks are the result of the inhomogeneous deformation

Lithotectonic units of the Cabeço de Vide Massif (Ossa-Morena Zone, SW Iberian Massif): a bedrock map to decipher superimposed orogenies

open access: yesJournal of Maps
This study provides a new cartographic framework for a geologically complex region in the SW Iberian Massif (central-east Portugal). We have redefined lithological ensembles and clarified structural relationships between rock types (unconformities and ...

The Dark Star of Baisun-tau: a history of cave exploration in Southern Uzbekistan, 1990–2013 [PDF]

open access: yes, 2014
Very little is known about the karst and caves in southern Uzbekistan, where some of the deepest caves in Asia have been discovered. In particular, the limestone plateau of the Baisun-tau mountain range has a tremendous potential for exploration.

A New Species of Myriopus (Heliotropiaceae) From Brazil

open access: yesFeddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT A new species of Myriopus (Heliotropiaceae), Myriopus chrysocalyx J.I.M. Melo & L.G. Sá, hitherto recorded for the Brazilian Northeastern is described and illustrated. Myriopus chrysocalyx can be readily recognized by its branches strigose to villous, and, mainly, for presenting leaf blade chartaceous to subfleshy, congested inflorescences, a ...

Climate‐Driven Habitat Suitability Modeling for the Vulnerable Species Euryops pinifolius A. Rich in Ethiopia: Implications for Conservation

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Euryops pinifolius, vulnerable plant species in Ethiopia's Afroalpine ecosystem, faces serious threats from overexploitation for fuelwood. Using the MaxEnt model (AUC = 0.985), this study identified key environmental factors‐such as temperature, altitude, vegetation cover, and precipitation seasonality‐affecting its current and future habitat ...

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Imaging the Deformation Belt of Western Hispaniola Island (Haiti) Using Multi‐Component Ambient Noise Cross‐Correlations

open access: yesGeophysical Research Letters
We apply ambient noise tomography to a seismic array from the Trans‐Haiti project to obtain a 2‐D shear wave velocity (Vs) across Haiti. We perform multi‐component noise cross‐correlation, measure Rayleigh wave phase velocity and its horizontal‐to ...
