Lava Tube System Development Defined by Multispectral Imaging and InSAR: The Case of the 2024 Eruption of Fernandina Volcano (Galápagos)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract Lava tubes are subsurface conduits within a lava flow that feed its advance. Lava tube detection is important to understand lava flow dynamics and to mitigate geohazards. Here we use InSAR‐derived surface motion data, in combination with shortwave and thermal infrared imagery, to delineate a ∼14 km long lava tube system at Fernandina volcano ...

Search for an artificially buried karst cave entrance using ground penetrating radar: a successful case of locating the S-19 Cave in the Mt. Kanin massif (NW Slovenia)

open access: yesInternational Journal of Speleology, 2016
The S-19 Cave was with its explored depth of 177 m one of the most important caves of the Mt. Kanin massif, but after its discovery in 1974, a huge snow avalanche protection dyke was constructed across the cave entrance.

New insights into the biology of the rare ectoparasitoid rhopalosomatid wasps (Hymenoptera: Rhopalosomatidae) in the Neotropics: parasitoid–host relationships in Brazil and Costa Rica

open access: yesAustral Entomology, Volume 64, Issue 4, November 2025.
Abstract Rhopalosomatidae (Hymenoptera, Vespoidea) are rare ectoparasitoid wasps that parasitize crickets (Grylloidea), with few records documented in the literature, which originate from the Nearctic and Australian regions. Here, we report the first record of Rhopalosomatidae larvae parasitizing crickets of the family Phalangopsidae in the Neotropics.

Hominin and carnivore roles during the formation of the early Middle Pleistocene site of Loreto (Venosa Basin, southern Italy)

open access: yesJournal of Quaternary Science, Volume 40, Issue 7, Page 1252-1268, October 2025.
ABSTRACT The site of Loreto (Venosa Basin, Italy) was first discovered in 1929 and subsequently excavated during the latter half of the 20th century. The excavation revealed three archaeo‐palaeontological levels, with the lowermost level (Level A) yielding the largest number of remains.
