Epigene and Hypogene Karst Manifestations of the Castile Formation: Eddy County, New Mexico and Culberson County, Texas, USA [PDF]

open access: yes, 2008
Permian evaporites of the Castile Formation crop out over ~1,800 km2 in the western Delaware Basin (Eddy County, New Mexico and Culberson County, Texas, USA) with abundant and diverse karst manifestations. Epigene karst occurs as well-developed karren on

Four novel taxa of cyanobacteria from a unique thermal cave habitat in Vromoner Canyon, Albania

open access: yesJournal of Phycology, Volume 61, Issue 5, Page 1394-1422, October 2025.
Abstract Thermal and cave habitats on nearly all continents have been a substantial source of new cyanobacterial genotypes and morphotypes that expanded with the dawn of the era of molecular phylogenetics. In this study, we investigated the cyanobacterial flora of an extreme habitat of recently discovered caves with sulfur‐rich thermal springs, using ...

Drift Reduction in Terrestrial Laser Scanning via Linear Dual Quaternion Interpolation

open access: yesThe Photogrammetric Record, Volume 40, Issue 192, October–December 2025.
This work introduces a terrestrial laser scanning (TLS) point cloud registration pipeline combining optimized fast global registration (keypoint extraction + fine‐tuning) and multiscale GICP refinement. A closed‐loop global model employs dual quaternion linear interpolation to correct trajectory drift, enhancing 3D reconstruction accuracy in TLS ...

New data on the biodiversity and distributional pattern of Coleoptera in the Carpathian landscape

open access: yesTravaux de l'Institut de Speologie Emile Racovitza, 2018
The faunal diversity and distributional pattern of species of Coleoptera in the Carpathians is fragmentarily and disproportionally known, the Buzau Mountains being one of the very poorly investigated geographic area, from coleopterological point of ...

Speleotourism in Slovenia: balancing between mass tourism and geoheritage protection

open access: yesOpen Geosciences, 2018
Slovenia is considered as the cradle of karst geotourism as cave tourism started there as early as the Middle Ages. To date more than 12,000 caves were discovered from which 22 have the status of tourist caves.

Molecular phylogenetics illuminates the evolutionary history and hidden diversity of Australian cave crickets (Orthoptera: Rhaphidophoridae)

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 975-987, October 2025.
A fossil‐calibrated phylogeny of Rhaphidophoridae revealed Australia at the centre of the radiation of the Southern Hemisphere subfamily Macropathinae, with the Australian biota consisting of at least five separate lineages. Crown‐Macropathinae originated in the Lower Cretaceous (ca.

Invertebrate communities from the mesovoid shallow substratum of the Carpatho-Euxinic area

open access: yesTravaux de l'Institut de Speologie Emile Racovitza, 2010
Between 1998 and 2008, the authors analyzed from a faunistic and zoogeographic point of view, 5 sites with different types of mesovoid shallow subtratum (MSS) from the karst areas of Dobrogea and the Carpathians.
