Global emergent responses of stream microbial metabolism to glacier shrinkage

Tom Ian Battin, Hannes Markus Peter, Massimo Bourquin, Nicola Deluigi, Tyler Joe Kohler, Michail Styllas

Most cryospheric ecosystems are energy limited. How their energetics will respond to climate change remains largely unknown. This is particularly true for glacier-fed streams, which interface with the cryosphere and initiate some of Earth's largest river s ...

Science on the Summit: Exploring Scientific Tourism Through the Lens of Eighteenth Century Mountain Ascents

Jérôme Baudry, Simon François Dumas Primbault, Ion-Gabriel Mihailescu

This contribution argues that a particular scientific context made summits a place of interest for eighteenth-century travelers. This development is connected to two particular scientific practices. First, the challenges raised by making the barometer into ...

Brief communication: Application of a muonic cosmic ray snow gauge to monitor the snow water equivalent on alpine glaciers

Rebecca Gugerli

Monitoring the snow water equivalent (SWE) in the harsh environments of high mountain regions is a challenge. Here, we explore the use of muon counts to infer SWE. We deployed a muonic cosmic ray snow gauge (mu-CRSG) on a Swiss glacier during the snow-rich ...

Grounding Resistance of a Hemispheric Electrode Located on the Top of a Finite-Height, Cone-Shaped Mountain

Marcos Rubinstein, Antonio Sunjerga, Farhad Rachidi-Haeri, Hamidreza Karami

In this letter, we present an analytical solution for the resistance of a hemispheric grounding electrode located on the top of a mountain. The mountain is modeled as a truncated cone with a finite height. Recently, a closed-form solution for the grounding ...

Calculation of the Grounding Resistance of Structures Located on Elevated Terrain

Marcos Rubinstein, Antonio Sunjerga, Farhad Rachidi-Haeri

We present an analysis of the response of a grounding electrode located on the top of a mountain. Specifically, we derive an analytical solution for the low-frequency response of a hemispheric grounding electrode buried on the top of a cone-shaped mountain ...

From the clouds to the ground - Effects of flow-precipitation interactions on snow distribution in complex alpine terrain

Franziska Gerber

Knowledge about the spatial distribution of seasonal snow is essential e.g. to efficiently manage fresh water resources or for hydro-power companies. The large-scale gradient of snow accumulation over mountain ranges is mainly determined by lifting condens ...

An Analysis of Lightning Activity in the Säntis Region through the Big Hiatus in Global Warming

Marcos Rubinstein, Mohammad Azadifar, Farhad Rachidi-Haeri, Amirhossein Mostajabi, Aleksandr Smorgonskii

The response of local lightning to local surface temperature is examined near the Säntis mountain (2502 m ASL) in the eastern Swiss Alps during the first of the two hiatuses in global warming covering the time periods 1940-1972 and 1998-2014. The mountain ...

Invasion by Fallopia spp. in a French upland region is related to anthropogenic disturbances

Thomas Spiegelberger

Within Europe, mountain ecosystems are generally less invaded by exotic plant species than are lowland areas. This pattern is commonly attributed to climatic harshness, which limits invasive species presence, and higher propagule pressure and rates of dist ...

Vegetation-environment relationships in alpine mires of the West Carpathians and the Alps

Lucia Sekulova

QuestionsHow do two distant mountain ranges differ in their vegetation-environment relationships, overall species composition and its variability and species richness of vascular plants and bryophytes in alpine fens and bogs? Is the floristic difference co ...

Sustainable Land-use Practices in European Mountain Regions under Global Change: an Integrated Research Approach

Alexandre Buttler

This Special Feature on sustainable land-use practices in European mountain regions presents results from the inter- and transdisciplinary research project MOUNTLAND. The goal was to investigate the sensitivity of the provision of ecosystem services to bot ...

Sustainable Land Use in Mountain Regions Under Global Change: Synthesis Across Scales and Disciplines

Alexandre Buttler, François Gillet, Adrienne Grêt-Regamey, Thomas Spiegelberger, Heike Lischke

Mountain regions provide essential ecosystem goods and services (EGS) for both mountain dwellers and people living outside these areas. Global change endangers the capacity of mountain ecosystems to provide key services. The Mountland project focused on th ...

On the geographic range of freshwater ﬁsh in river basins

Andrea Rinaldo, Enrico Bertuzzo

We study the observed geographic distribution of freshwater fish species in the Mississippi-Missouri river system, focusing on the size and spatial distribution of geographic ranges. We use a particular metric of geographic distribution known as environmen ...
