Abstract. Glacier forefields have long provided ecologists with a model to study patterns of plant succession following glacier retreat. While plant-survey-based approaches applied along chronosequences provide invaluable information on communities, the “space-for-time” approach assumes environmental uniformity and equal ecological potential across sites does not account for spatial variability in initial site conditions. Remote sensing provides promising avenue assessing colonization...
Most of the world’s mountain glaciers have been retreating for more than a century in response to climate change. Glacier retreat is evident on all continents, and rate has accelerated during recent decades. Accurate, spatially explicit information position glacier margins over time useful analyzing patterns measuring reductions surface area. This also essential evaluating how ecosystems are evolving due warming attendant retreat. Here, we present non-comprehensive dataset showing multiple...
Landscapes nearby glaciers are disproportionally affected by climate change, but we lack detailed information on microclimate variations that can modulate the impacts of global warming proglacial ecosystems and their biodiversity. Here, use near-subsurface soil temperatures in 175 stations from polar, equatorial alpine glacier forelands to generate high-resolution temperature reconstructions, assess spatial variability change 2001 2020, estimate whether heterogeneity might buffer severity...
By 2100 and due to global warming, 49% 83% of the world's terrestrial glaciers will disappear depending on which climate trajectory is followed. The resulting proglacial landscapes create new challenges opportunities for downstream socio-ecological systems.In high Andes, a region inhabited millennia, glacier retreat exacerbates socio-economic challenges, including risks species extinction, water contamination from acid rock drainage, slope instability, reduced availability, lake outburst...
Springtails (Hexapoda: Collembola) are unique among Alpine arthropods for including cryophilic species, able to live in contact with glacial ice, the so‐called ‘glacier fleas’. Despite being historically recorded, their taxonomy and distribution largely unknown. In this article, we present first comprehensive study of ice‐dwelling springtails (family Isotomidae) European Alps Apennines. Morphological molecular analyses two mitochondrial genes ( cox1 16S ) were performed after an extensive...
Abstract Alpine glaciers worldwide will lose most of their volume by the end 21st century, placing alpine ecosystems and human populations at risk. The new lands that emerge from retreating provide a host challenges for ecological adaptation to climate change. In these novel proglacial landscapes, succession natural hazards interplay with local agriculture, hydroelectric production, mining activities, tourism. Research has emphasized importance understanding around socio‐environmental...
Summary The development of terrestrial ecosystems depends greatly on plant mutualists such as mycorrhizal fungi. global retreat glaciers exposes nutrient‐poor substrates in extreme environments and provides a unique opportunity to study early successions fungi by assessing their dynamics drivers. We combined environmental DNA metabarcoding measurements local conditions assess the succession communities during soil 46 glacier forelands around globe, testing whether drivers differ between...
Worldwide, mountain glaciers are shrinking rapidly. Consequently, large areas becoming available for the development of novel alpine ecosystems. These harsh environments, however, delay primary succession. In this study with a local community, we conducted an inclusion experiment to investigate whether Llama glama influences soils and vegetation succession following glacial retreat. At foot Uruashraju glacier in Cordillera Blanca, Peru (~ 4680 m.a.s.l.), established four llama plots control...
Abstract The worldwide retreat of glaciers is causing a faster than ever increase in ice‐free areas that are leading to the emergence new ecosystems. Understanding dynamics these environments critical predicting consequences climate change on mountains and at high latitudes. Climatic differences between regions world could modulate biodiversity functionality after glacier retreat, yet global tests this hypothesis lacking. Nematodes most abundant soil animals, with keystone roles ecosystem...
Abstract Mechanisms underlying plant succession remain highly debated. A global quantification of the relative importance species addition versus replacement is lacking due to local scope most studies. We quantified their role in variation communities colonizing forelands 46 retreating glaciers distributed worldwide, using both environmental DNA and traditional surveys. Both mechanisms concur determining community changes over time but varied along successions. Taxa predominated immediately...

New soils formed after glacier retreat due to climate change can provide insights into the rates of soil formation during Anthropocene. Recently deglacierized terrains (since Little Ice Age) are subject weathering and pedogenesis, freshly exposed sediments prone react readily with environment. This study aims determine impact parent material time on physical chemical properties nine proglacial landscapes distributed in Tropical Andes Alps. A total 188 samples were collected along...
During the Anthropocene, climate warming has accelerated retreat of mountain glaciers worldwide, exposing new areas to weathering, vegetation colonization, and soil formation. In light probable changes such as extremes, understanding factors that control organic carbon (SOC) nitrogen build-up are crucial for proglacial soils ecosystem To this end, we examine evolution SOC, (total N NH4+), phosphorus (available P) along nine 120-year chronosequences deglacierization distributed between...
