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...
Abstract Weather and climate conditions drive the evolution of tropical glaciers which play an important role as water reservoirs for Peruvian inhabitants in arid coast semi-arid Andean region. The scarcity long-term high-quality observations over has motivated extensive use reanalysis data to describe climatic these glaciers. However, representativeness uncertainties products are still poorly constrained. This study evaluates ability ERA5-Land (ERA5L) reproduce hourly monthly 2 m air...
Abstract. Located in Peru’s Cordillera Blanca, the Queshque Glacier (~9.8° S) has experienced nearly continuous retreat since mid-20th century. More recently, this trend accelerated after glacier transitioned from land to lake terminating. We use observations of surface height change (1962–2008), bed topography, and climatology evaluate relative drivers Queshque’s evolution 1962–2020. Six Open Global Model ensemble members differing climatic sensitivity are calibrated fit mass balance rate...
Tropical glaciers are highly vulnerable to climate change, with their mass balance influenced by temperature and precipitation, affecting the snow accumulation area (SCA). This study aimed develop an open-source, cloud-based tool identify SCA using Landsat imagery analyse annual variations in Cordillera Blanca (CB), Peru, from 1988 2023. The total glacier was obtained MapBiomas - Peru data. Automatic classification performed spectral indices, slope gradient filtering, morphological Otsu...
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...
Abstract Tropical high‐mountain permafrost has a unique thermal regime due to its exposure strong solar radiation and rough surface snow morphology, which reduce ground heat transfer from the surface. Latent higher albedo that occur during snow‐covered season contribute positive feedback supports presence of permafrost. This preliminary study reports on state characteristics tropical mountain in Peru. work also evaluates potential combined impact El Niño–Southern Oscillation (ENSO) Coropuna...
Abstract Andean glaciers have melted rapidly since the 1960s. While some melting is likely due to anthropogenic climate change driven by increasing greenhouse gases, deposition of light-absorbing particles such as black carbon (BC) may also play a role. We hypothesize that BC from fires in Amazon Basin and elsewhere be deposited on glaciers, reducing surface albedo inducing further melting. Here we investigate role changes Andes for 2014–2019 combining atmospheric chemistry modeling with...
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. This article presents a comprehensive hydrometeorological dataset collected over the past two decades throughout Cordillera Blanca, Peru. The data-recording sites, located in upper portion of Rio Santa valley, also known as Callejon de Huaylas, span an elevation range 3738–4750 m a.s.l. As many historical hydrological stations measuring daily discharge across region became defunct after their installation 1950s, there was need for new to be installed and opportunity increase...
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...
Abstract In the Peruvian Andes, first light rainfalls towards end of dry season in August-September are known as pushpa . Softening soils and improving sowing conditions, these rains crucial for planting dates agricultural planning. Yet remains to date unexplored literature. This study uses observations convection-permitting model simulations describe characteristics Rio Santa valley (Peru). Comparing an observed case August 2018 with a wet event same season, we find coincide upper-level...
