Homogeneous Environmental Selection Structures the Bacterial Communities of Benthic Biofilms in Proglacial Floodplain Streams

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Jade Brandani, Tyler Joe Kohler, Stylianos Fodelianakis

Streams draining proglacial floodplains harbor benthic biofilms comprised of diverse microbial communities. These high-mountain ecosystems are rapidly changing with climate warming, and it is therefore critical to better understand the mechanisms underlyin ...

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 ...

Above- and below-ground responses to experimental climate forcing in two forb species from montane wooded pastures in Switzerland

Alexandre Buttler, Konstantin Svetlozarov Gavazov

Mountain ecosystems are particularly threatened by ongoing climate change and the species composition of high elevation grasslands is already changing. An open research question is how these ecosystems will adapt to changes in their key environmental const ...

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 ...

Ecological response of tree saplings to simulated climate change along an elevational gradient (CLIMARBRE)

María Paula Sanginés De Cárcer

Switzerland will face higher temperature increases than the global average, which will have strong impacts on the mountain ecosystems. How tree species will respond to future climate change scenarios, and what mechanisms will they adopt, remains as a gap o ...

Responses of antinomic foliar traits to experimental climate forcing in beech and spruce saplings

Alexandre Buttler, Rodolphe Schlaepfer, Constant Signarbieux, María Paula Sanginés De Cárcer

Global warming is predicted to have a strong impact on mountain ecosystems. Subalpine sylvopastoral systems are very sensitive to climate change, which puts their future sustainability at stake. These ecosystems are mostly dominated by spruce and beech, an ...

Bodennahe atmosphärische Prozesse und ihre Wirkung auf die hochalpine Schneedecke

Michael Lehning

The atmospheric boundary layer over mountains shows a wide range of special characteristics, especially when mountains are covered with snow. This contribution discusses how cloud dynamics, prferential deposition and snow transport shape the obeserved high ...

New lakes in deglaciating high-mountain regions – opportunities and risks

Anton Schleiss

In connection with the ongoing disappearance of glaciers in cold mountains, a great number of new lakes come into existence. The sites and approximate formation time of such potential new lakes can be realistically modelled. This provides an important know ...

Altitude: architecture et environnement de haute montagne

Estelle Lépine

At the centre of the research is the preservation of the countryside which is highlighted and studied through an architectural approach which focuses on cabins in the high mountains. The projects must reflect upon territorial, global and sustainable aspect ...

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 ...

Elevation dependency of mountain snow depth

Michael Lehning

Elevation strongly affects quantity and distribution patterns of precipitation and snow. Positive elevation gradients were identified by many studies, usually based on data from sparse precipitation stations or snow depth measurements. We present a systema ...

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 ...

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 ...

Radar for hydrology: unfulfilled promise or unrecognized potential?

Alexis Berne

Hydrology requires accurate and reliable rainfall input. Because of the strong spatial and temporal variability of precipitation, estimation of spatially distributed rain rates is challenging. Despite the fact that weather radars provide high-resolution (b ...

Statistical modelling of ground temperature in mountain permafrost

Anthony Christopher Davison, Juliette Ferial Blanchet

Permafrost consists of soil and rocks that remain at 0 degrees C or below for at least two consecutive years. In mountains, permafrost ground ice acts like cement, stabilizing rock walls. Its degradation, following climate warming, may lead to slope instab ...

Wireless Sensor Networks for Environmental Monitoring: The SensorScope Experience

Martin Vetterli, Guillermo Barrenetxea Kobas, François Ingelrest

While wireless sensor networks have been extensively studied in the past few years, most results are of theoretical nature and were obtained outside of a practical context. This can be problematic for real applications, especially in the area of environmen ...
