Presentation
Full-text available
The vast majority of studies in the ecological literature last less than three years, and only a small number of research works capture unusual events. To detect changes in high-mountain ecosystems, long-term research is mandatory, as these areas are important bellwethers of climate change. The LTER macrosite "Northwestern Italian Alps" includes th...
Article
Full-text available
Since both the EU Erasmus+ program and UNESCO Global Geoparks aim at developing models of best practices, a shared playground for common activities can be found in high geodiversity and rich geoheritage areas to promote innovative education and professional perspectives in the ecological transition. Two consecutive Erasmus+ cooperative partnerships...
Article

Progressive glacier retreat can deeply impact high-mountain areas. New glacier lakes are forming and potential connected opportunities (e.g., geosystem services) and risks (e.g., floods) are emerging. In the last decades, glacier lakes in the European Alps have increased in number and size, including in the study area (Aosta Valley Region, NW Alps,...

New strategies for preservation of geodiversity and geosystem services need to be developed for mountain areas that are vulnerable to climate change and human activities. Detailed geomorphological surveys and geosystem services analyses have been carried out in the Indren-Cimalegna area, southern slope of Monte Rosa (Western Italian Alps). From rem...

In the framework of geosite management, specific targeted symbols for geomorphological legends are still lacking. Concerning geosites of geomorphological interest, geomorphological mapping requires targeted symbols in relation to goals and applications, either concerning geomorphic hazards and risk detection or the enhancement of resources, in part...
Article
Alpine soils can provide valuable paleo-environmental information, representing a powerful tool for paleoclimate reconstruction. However, since Pleistocene glaciations and erosion-related processes erased most of the pre-existing landforms and soils, reconstructing soil and landscape development in high-mountain areas can be a difficult task. In pa...

Mount Meager, a glacier-clad volcanic complex in British Columbia, Canada, is known for its large landslides, as well as a major eruption about 2360 years ago. In 2010, after decades of glacier retreat, the south flank of Mount Meager collapsed, generating a huge (53 Mm³) landslide. In 2016, fumaroles formed ice caves in one of the glaciers on the...

Mt. Meager is a glacier-clad volcanic complex in southwest British Columbia. In the summer of 2010, melting snow and ice caused by warm weather triggered the collapse of 53 Mm 3 of rock and debris from Mt. Meager's south flank, generating the largest historic landslide in Canada. In 2016 fumaroles formed ice caves in one of its glaciers, raising co...

Because of extensive Pleistocene glaciations, which erased most of the previously existing soils, slope steepness and climate conditions favoring soil erosion, most soils observed on the Alps (and in other mid-latitude mountain ranges) have developed during the Holocene. However, in few sites, particularly in the outermost sections of the Alpine ra...

Permafrost degradation affects hydrochemistry of surface waters. In particular, evidence of modifications of water quality has been collected in mountain headwaters impacted by rock-glacier thawing. Rock glaciers are slowly flowing mixtures of debris and ice-rich permafrost, and melting ice inside them has been reported to affect surface water hydr...

In 2010, the south flank of Mount Meager failed catastrophically, generating the largest (53 ± 3.8 × 10⁶ m³) landslide in Canadian history. We document the slow deformation of the edifice prior to failure using archival historic aerial photographs spanning the period 1948–2006. All photos were processed using Structure from Motion (SfM) photogramme...
Article
Rock glaciers are slowly flowing mixtures of debris and ice occurring in mountains. They can represent a reservoir of water, and melting ice inside them can affect surface water hydrochemistry. Investigating the interactions between rock glaciers and water bodies is therefore necessary to better understand these mechanisms. With this goal, we eluci...

Aosta Valley (NW-Alps, Italy) is the region with the largest glaciarized area of Italy (133.73 km2). Like the other alpine regions it has shown a significant glacier retreat starting from the end of the Little Ice Age (LIA, ca. 1850 AD), by losing about 60% of its glaciarized area. As a direct consequence of glacier shrinkage, within glacially-scul...
