Abstract High mountainous areas are geomorphologically active environments which strongly shaped by redistribution of sediments and soils. With the projected climate warming in twenty‐first century continued retreat glaciers, area newly exposed, highly erodible soils will increase. This presents a need to better understand quantify erosion processes young soils, as an increase erodibility could threaten human infrastructure (i.e. hydroelectric power, tourist installations settlements). While...
Investigating changes in belowground functional plant traits is an important step toward a better understanding of vegetation dynamics during primary succession. However, alpine glacier forelands, we still lack accurate assessment rooting patterns. In this study, established two proglacial chronosequences with contrasting bedrocks to investigate patterns and biomass allocation terrain age. We extracted soil cores up 1 m depth measured root every 10 cm each drilled core. Furthermore, sampled...
Abstract Aims The stability of hillslopes is an essential ecosystem service, especially in alpine regions with soils prone to erosion. One key variable controlling hillslope soil aggregate stability. We aimed at identifying dominant controls vegetation parameters on and analysed their importance for during landscape development. Methods quantified the coefficient (ASC) measured plant cover, diversity, root mass length, density (RMD, RLD) along two chronosequences contrasting bedrocks...
Abstract Questions Primary plant succession is expected to be driven by habitat filtering and competitive exclusion. However, such findings typically come from experimental or single‐site case studies. As a result, we lack field studies that investigate the functional community structures across successional series with differing site conditions. Here, address following question: how do trait patterns diversity change along two chronosequences distinct bedrocks? Methods We established soil...
Soil development and erosion are important opposing processes in the evolution of high-mountainous landscapes, though their dynamics not fully understood. We compared soil between a calcareous siliceous chronosequence central Swiss Alps at high altitudes, which both cover formation over Holocene. calculated element mass balances, long-term rates based on meteoric 10Be we determined formation. also analyzed shifts mineralogical composition, weathering indices, particle size distribution,...
Abstract Tree diversity may buffer the negative impact of drought events according to insurance hypothesis. During extreme pan-European 2018, we tested whether tree species richness modulated impacts on communities a young experiment in Freiburg, Germany. We utilized drone-based hyperspectral images capture early symptoms stress indicated by variation Normalized Difference Vegetation Index (NDVI), and ground-based measures that are indicative canopy function, including Plant Area (PAI) leaf...
Abstract. Soil hydrologic processes play an important role in the hydro-pedo-geomorphological feedback cycle of landscape evolution. properties and subsurface flow paths both change over time, but due to a lack observations, water are often not properly represented soil evolution models. We investigated across chronosequence calcareous glacier forefield at Griessfirn Swiss Alps. Young soils developed from parent material usually have high pH value, which likely affects vegetation development...

Many different animal plant species have been able to establish themselves as archaeophytes Central Europe since the beginning farming Neolithic period. However, increasing intensification agriculture has led fact that many typical land are now under threat. This decline is particularly well documented for higher plants, birds insects. For...
Abstract Excessive tree mortality is a global concern and remains poorly understood as it complex phenomenon. We lack temporally continuous coverage on data. Ground-based observations mortality, e.g ., derived from national inventories, are very sparse, not standardized spatially explicit. Earth observation data, combined with supervised machine learning, offer promising approach to map over time. However, global-scale learning requires broad training data covering wide range of...
Abstract. Hydrologic processes play an important role in the hydro-pedo-geomorphological feedback cycle of landscape evolution. Soil properties and subsurface flow paths change over time, but due to lack observations hydrologic such as water are often not properly considered soil evolution studies. We investigated during development calcareous glacier forefield at Griessfirn Swiss Alps. While main focus was on path formation preferential with development, we also looked impact irrigation...

<p>High mountainous areas are strongly shaped by redistribution processes of sediments and soils. Due to the projected climate warming continued retreat glaciers in 21<sup>st</sup> century, we can expect area newly exposed, highly erodible soils increase. While soil vegetation development is increasingly well understood quantified, it has rarely been coupled erosion. The aim this study was assess how erosion rates change with surface age. We...
