open access: yesActa Carsologica, 2012
Our friend, colleague, supervisor, chairman... our Charlie, who came back from the underground so many times, entered it the last time, without return. On January 25, 2012 the Earth opened for him, as would say the old Romans: “Mundus subterraneus patet”.

Dendritic subglacial drainage systems in cold glaciers formed by cut-and-closure processes [PDF]

open access: yes, 2014
The routing and storage of meltwater and the configuration of drainage systems in glaciers exert a profound influence on glacier behaviour. However, little is known about the hydrological systems of cold glaciers, which form a significant proportion of ...

Potential geographic displacement of Chagas disease vectors under climate change

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 4, Page 709-717, December 2025.
As a result of modelling the potential distribution of 55 triatomine species in the Neotropical region, with climate change projected for up to 2050, we found no significant changes. With climate change projected for up to 2080 in the Neotropical region, we see a significant potential for the migration of 55 species of triatomines towards the Amazon ...

La didattica speleologica CAI – Studio, tutela e fruizione di parchi e aree carsiche in sicurezza [PDF]

open access: yes, 2013
Ad un breve passaggio storico sulla SNS seguono argomentazioni sulla peculiarità degli ambienti carsici, visti non come riserve lontane dall’uomo ma come preziose peculiarità dell’ambiente da far conoscere e poter fruire in sicurezza.

Making vertebrate fossil radiocarbon dates more useful for global scientific research

open access: yesJournal of Quaternary Science, Volume 40, Issue 8, Page 1309-1335, November 2025.
ABSTRACT Radiocarbon dating of bones is essential for reconstructing timelines of species' occurrences, domestication, extinction, migrations, and interactions with Quaternary environments. Many studies compile these chronologies at continental to global scales by aggregating radiocarbon dates from various sources, often balancing data quantity and ...

Genetic turnovers and northern survival during the last glacial maximum in European brown bears

open access: yesEcology and Evolution, 2019
The current phylogeographic pattern of European brown bears (Ursus arctos) has commonly been explained by postglacial recolonization out of geographically distinct refugia in southern Europe, a pattern well in accordance with the expansion/contraction ...

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 ...
