Water vapor transport in snowpacks

This thesis is an in-depth treatment of water vapor transport in snowpacks and its impacts on snow structure. The aim is to better understand this transport process and to lay the basis for a model representation in physics-based multi-layer snow models. O ...

Mapping forest in the Swiss Alps treeline ecotone with explainable deep learning

Devis Tuia, Thiên-Anh Claris Nguyen, Benjamin Alexander Kellenberger

Forest maps are essential to understand forest dynamics. Due to the increasing availability of remote sensing data and machine learning models like convolutional neural networks, forest maps can these days be created on large scales with high accuracy. Com ...

Changes in Climatology, Snow Cover, and Ground Temperatures at High Alpine Locations

Michael Lehning

Knowledge about changes in ground temperatures under a changing climate is important for many environmental, economic, and infrastructure applications and can be estimated by transient numerical simulations. However, a full annual cycle of precipitation da ...

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

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

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 ...

The Legacy Effects of Winter Climate on Microbial Functioning After Snowmelt in a Subarctic Tundra

Konstantin Svetlozarov Gavazov

Warming-induced increases in microbial CO2 release in northern tundra may positively feedback to climate change. However, shifts in microbial extracellular enzyme activities (EEAs) may alter the impacts of warming over the longer term. We investigated the ...

Calculation of the Grounding Resistance of Structures Located on Elevated Terrain

Farhad Rachidi-Haeri, Marcos Rubinstein, Antonio Sunjerga

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 ...

Disturbance-grazer-vegetation interactions maintain habitat diversity in mountain pasture-woodlands

Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer

Low-intensity livestock grazing is a widespread management tool in order to maintain habitat diversity in mountain pasture-woodlands for nature conservation purposes. Historical photographs indicate that forest disturbance significantly contributed to fore ...

Attenuation of wind-induced pressure perturbations in alpine snow

Marc Parlange, Wolf Hendrik Huwald, Chad Higgins

Windpumping has been identified as a process that could potentially enhance sublimation of surface snow at high forcing frequency and spawn air movement deeper in firn at lower frequencies. We performed an experiment to examine the relationship between hig ...

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 ...

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

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

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 ...

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 ...

A study on the uplift mechanism of Tongjiezi dam using a coupled hydro-mechanical model

During filling in 1992 of the Tongiiezi reservoir, in Southwest China, it was noticed that the dam body and the rock masses on the right side of the valley were uplifted up to 22.2 mm and 24.3 mm respectively. After reservoir filling in 1993, the uplift co ...

Long-term dynamics of aboveground fungal communities in a subalpine Norway spruce forest under elevated nitrogen input

Rita Bütler Sauvain, François Gillet, Simon Egli

As anthropogenic N deposition has been suspected to be the main reason for the decline of macromycetous sporocarp production in forest ecosystems, various N-fertilization experiments were started in the mid 1990s. The dynamics of ectomycorrhizal (root-inha ...

Competitive effects of herbaceous vegetation on tree seedling emergence, growth and survival: does gap size matter?

Alexandre Buttler, François Frelechoux, Charlotte Vandenberghe

Question: What is the effect of gap size on the seedling emergence, growth and survival of four common tree species in wooded pastures? Location: A pasture in the Jura mountains, Switzerland. Methods: Seeds were sown in a complete three-way factorial desig ...

The influence of cattle activity on tree regeneration in wood-pastures

Charlotte Vandenberghe

Wood-pastures are semi-natural, highly biodiverse systems maintained by traditional extensive agriculture. They are used for grazing and timber. The shifting mosaics of grassland, shrub thickets and woodland patches in these systems are driven by large her ...
