Karst record of Holocene climate and human-induced changes in surface processes in the northern Apennines of Italy
A new study reveals that human land-use changes, particularly the slash-and-burn technique practiced since the Copper Age, significantly increased soil erosion and sediment flux into karst systems in the northern Apennines of Italy. The research, conducted on sediments from Tana della Mussina Cave (TdMC), shows that clastic sedimentation surged after 5500 years BP due to deforestation, leading to higher charcoal and heated soil remnants in the cave's deposits. This finding underscores early human impact on Earth's Critical Zone processes, with implications for understanding long-term environmental changes. The study combines sediment analysis, speleothem records, and archaeological evidence to reconstruct Holocene hydrological and anthropogenic influences on karst dynamics.
Combining the 3D Geological and Geostatistical Modelling of Gypsum Concentration, Using Historical Borehole and Blasthole Information
A novel integration of 3D geological and geostatistical modeling enhances the precision of gypsum concentration estimation at the UNESCO-listed 'Monte Tondo' quarry, Italy. By combining historical borehole data with blasthole information, researchers achieved a more accurate representation of gypsum deposits, reducing geological risk and improving mining efficiency. This approach addresses long-standing challenges in small-scale operations, offering a sustainable solution that aligns with environmental regulations. The study demonstrates the potential of geostatistical techniques beyond large metal mines, paving the way for broader adoption in industrial mineral extraction.
Genetic Diversity and Distribution of Italian Cave Crickets (Dolichopoda): Toward a Better Understanding of Lineage Structure
Research on Italian cave crickets (Dolichopoda) reveals two previously unrecognized lineages within the species D. geniculata, refining our understanding of their genetic diversity and distribution across the Apennines. By sequencing mitochondrial markers (cox1 and 16S) from 18 populations, scientists identified distinct lineages and updated the known ranges for D. geniculata, D. letitiae, and D. schiavazzii in the northern Apennines. These findings contribute to ongoing efforts toward a taxonomic revision of the group, highlighting the importance of cave crickets as key indicators of subterranean biodiversity. The study underscores the need for further exploration to unravel the complex lineage structure of these species.
Geological Map of the Frasassi Gorge (Northern Apennines, Italy)
A new 1:10,000-scale geological map of the Frasassi Gorge (Northern Apennines, Italy) reveals intricate tectono-sedimentary contacts and structural features that refine our understanding of Jurassic paleogeography and post-Jurassic deformation in the region. The study integrates surface and cave surveys to provide a detailed subdivision of the Calcare Massiccio Formation (MAS), improving correlations with adjacent Jurassic units and the Maiolica Formation. Notably, it documents neptunian dykes both at the surface and within caves, suggesting that the Frasassi high was an elongated NW–SE block bounded by conjugate oblique-slip normal faults later reactivated during folding. This updated framework offers valuable insights for future geological research in this UNESCO-listed evaporitic karst system.

A fifteen-year review by the IUCN highlights the significant potential of UNESCO World Heritage Sites for geoscience education and nature conservation. The study evaluates 13 nominations from 12 countries, spanning diverse landscapes such as the Central Highlands of Sri Lanka, China Danxia, and the Evaporitic Karst Caves of Northern Apennines. It emphasizes the importance of integrating natural history and geological conservation into geoscience curricula to foster a broader understanding of environmental and social subjects. The research underscores the value of these sites in promoting geo-education and sustainable conservation practices.
Gypsum cave notches and their palaeoenvironmental significance: A combined morphometric study using terrestrial laser scanning, traditional cave mapping, and geomorphological observations
A multidisciplinary study on gypsum cave notches in the northern Apennines reveals a consistent paleocurrent flow direction from ESE to WNW, supporting the ancient resurgence nature of the cave system. Despite inconclusive results from individual methods—such as terrestrial laser scanning and traditional cave mapping—the collective evidence suggests that water flow gently inclined toward the present main entrance, corroborated by sediment imbrication patterns. This research highlights the potential of combining geostatistical analyses with geomorphological observations to unravel paleoenvironmental dynamics in karst systems.
Long-Term Dynamics of a Cave Salamander Population in a Region under Changing Climate
A 27-year study of Strinati's Cave Salamanders (Speleomantes strinatii) in the Northern Apennines reveals that their population dynamics remain stable despite regional climate change. While local temperatures have risen steadily, precipitation has stayed constant, yet no directional trends were detected in salamander abundance, adult sex ratio, recruitment, or growth rates. The population's complex fluctuations suggest interactions between lagged density dependence and external factors, likely buffered by the thermal inertia of their subterranean habitat. This finding highlights the resilience of long-lived cave-dwelling species to aboveground climate signals.
Different patterns of introgression in a three species hybrid zone among European cave salamanders
A previously undocumented three-species hybrid zone among European cave salamanders (Plethodontid) has been identified in the Northern Apennines, involving Speleomantes strinatii, S. ambrosii, and S. italicus. This discovery expands the known distribution of these species by 21 new sites and reveals complex introgression patterns, with asymmetric genetic exchange favoring S. italicus mitogenome in hybrids. The study employed mitochondrial (Cytb, ND2) and nuclear markers (NCX1 SNPs) to uncover strong mitonuclear discordance, where mitochondrial genes show geographic structure while nuclear alleles coexist across species boundaries. This finding suggests that behavioral, genetic, and ecological factors collectively influence hybridization dynamics in this unique system.
Foraging success is differently affected by local climate in two syntopic forest-dwelling salamanders
Two syntopic forest-dwelling salamanders exhibit distinct foraging strategies influenced by local climatic conditions. Salamandrina perspicillata increases foraging success during prolonged rainfall with higher temperatures and larger body sizes, while Speleomantes strinatii shows reduced foraging success with rising temperatures, unaffected by rainfall. These differences likely stem from species-specific adaptations to dehydration resistance and body size. The study analyzed 11 populations across eight sites in the Northern Apennines, Italy, using prey item counts to assess foraging success under varying climatic variables.
Domitius Culsu sp. nov. (Araneae, Nestici-dae), a new troglobiont spider from Italy with notes on Italian nesticids of the genus Domitius Ribera, 2018
A new troglobiont spider species, Domitius culsu sp. nov., has been discovered in the caves of Northern Apennines, Italy. This finding expands the known diversity of the genus Domitius Ribera, 2018, which is characterized by its restricted distribution along the Apennine mountain chain and deep adaptation to cave life. Molecular and morphological analyses confirm the validity of D. culsu sp. nov. and reveal its close relationship with other Italian Domitius species, as well as a notable affinity with species from the Iberian Peninsula. The discovery is significant for conservation due to the spider's potential susceptibility to external disturbance and its extremely limited distribution.
Implications for central Italy paleoclimate from 95,000 yr B.P. until the early Holocene as evident from Frasassi Cave speleothems
A composite δ18O and δ13C record from Frasassi Cave speleothems in central Italy's Apennines reveals unique paleoclimate dynamics distinct from other Mediterranean regions between 95,000 and 10,000 years ago. Unlike Western and Eastern Mediterranean records, Frasassi data show no significant δ18O decrease during the sapropel S3 period (ca. 86,000–83,000 yr B.P.), suggesting limited hydrological activity or different rainfall sources. During the transition from MIS 5 to glacial MIS 4 (ca. 83,000–65,000 yr B.P.), Frasassi δ18O values decreased while others increased, aligning with Northern Hemisphere temperature trends. A pronounced isotopic event between ca. 54,500 and 52,500 yr B.P., marked by warming and pluvial conditions, was consistent across the Mediterranean but followed by a shift to colder conditions. The study highlights regional climate variability during the last glacial and early Holocene transition, with instability evident in Frasassi δ13C oscillations.
Evaporite karst in Italy: a review
Evaporite karst, formed by gypsum and anhydrite, is a rare but significant geological phenomenon found primarily along the northern border of Italy's Apennine chain (Emilia-Romagna and Marche), as well as in Calabria and Sicily. Recent discoveries in Piedmont's underground gypsum mines have expanded our understanding of these unique landscapes. Multidisciplinary studies from the late 20th century provided a comprehensive overview, while more recent research has focused on detailed investigations in Emilia-Romagna and Sicily. Additionally, sinkholes related to Permian-Triassic gypsum have been studied in Friuli Venezia Giulia. This review synthesizes current knowledge, highlighting new findings and promoting further exploration of these special karst regions.
Geosciences: a tool in a changing world - Congresso congiunto SGI-SIMP-AIV-SOGEI, Pisa 3-6 settembre 2017

Participants observed brittle and ductile deformations across different structural levels, linking outcrop-scale structures to mountain-scale folds like pluridecametric folds. The Antro del Corchia cave provided insights into karstification processes, while the Levigliani mine highlighted historical mineralization activities. Interactive lab sessions focused on rock classification, age determination, and geological map interpretation, offering hands-on learning experiences for teachers.
Late quaternary speleogenesis and landscape evolution in the northern Apennine evaporite areas
Research reveals that gypsum caves in the northern Apennines, including some of the world's longest epigenic cave systems, began forming at least 600,000 years ago, challenging long-held assumptions about their age. The study used uranium-thorium dating of speleothems from 14 caves to determine that speleogenesis peaked during cold climate stages when surface rivers formed terraces and aggradation occurred. It also estimated that it took approximately 200,000 years for the dismantling of impervious sediments covering gypsum beds and the development of a mature surface drainage network. This finding significantly advances understanding of evaporite karst evolution in rapidly uplifting regions.
Gypsum caves as indicators of climate-driven river incision and aggradation in a rapidly uplifting region
Subhorizontal gypsum caves in the Northern Apennines, Italy, serve as indicators of climate-driven river incision and aggradation. These caves form during cold periods with stable river beds, while renewed cave formation occurs rapidly during river entrenchment. U-Th dating of calcite speleothems provides minimum age constraints for cave passage formation, revealing that speleothem ages coincide with warmer, wetter periods when CO2 availability in soils was greater. This climate-driven model suggests a broader applicability to karst systems in temperate, uplifting regions, offering insights into the interplay between geological processes and climatic conditions.
Soil-gas survey of liquefaction and collapsed caves during the Emilia seismic sequence
A soil-gas survey conducted during the Emilia seismic sequence revealed significant variations in carbon dioxide (CO2) and methane (CH4) fluxes from collapsed caves, including newly formed ones, indicating dynamic subsurface processes linked to seismic activity. The study, focused on the epicentral area of northern Italy's Ferrara Arc—a region with active thrust-related folds—highlighted the interplay between liquefaction phenomena and ground fractures following the May 2012 mainshock. Researchers measured soil-gas emissions in both pre-existing and newly identified collapsed caves, providing insights into the subsurface response to seismic events. The findings contribute to understanding the geodynamic behavior of evaporitic karst systems within UNESCO-recognized sites, offering critical data for hazard assessment.
River reversals into karst springs: A model for cave enlargement in eogenetic karst aquifers
A new model for cave enlargement in eogenetic karst aquifers is proposed, linking river reversals into karst springs to significant geological processes. The study highlights that Jurassic rifting in the Southern Alps and Northern Apennines occurred rapidly (2-4 million years) during the late Hettangian to early Sinemurian period, followed by stable post-rift sedimentation. Key differences in extensional tectonic styles between the Northern Apennines and Southern Alps are attributed to contrasting rheologies influenced by thick evaporite layers (up to 2 km) underlying thin carbonate platforms (up to 1.3 km). The Northern Apennines exhibit diffuse, shallow thin-skinned stretching, while the Southern Alps show thicker, deeper crustal deformation with larger fault spacing. This research provides insights into the structural and stratigraphic controls on karst development in evaporitic environments.
