Snowpack regimes of the Western United States

Snow accumulation and melt patterns play a significant role in the water, energy, carbon, and nutrient cycles in the montane environments of the Western United States. Recent studies have illustrated that changes in the snow/rainfall apportionments and sno ...

Record-setting forest stress in the Rocky Mountains caused by low snowfall and high potential evapotranspiration, consistent with expected future conditions

Ernesto Trujillo Gomez

Projections of future climate for the Southwestern U.S. and other semi-arid regions globally include reductions in mountain snow accumulation and increased summer potential evapotranspiration. These changes may significantly alter runoff production, evapot ...

Do peatlands hibernate?

Alexandre Buttler, Vincent Eric Jules Jassey, Constant Signarbieux, Robert Thomas Edmund Mills

Winter seasonality with low amounts of incoming radiation, frost and snow cover characterize large areas at mid- and high latitudes, especially in the arctic and in mountain ranges. Because of these adverse conditions, it is often assumed that ecosystem pr ...

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

Alexandre Buttler, Adrienne Grêt-Regamey, François Gillet, 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 ...

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 ...

Approximate solution of the probability density function of bedload transport rate over multiple time scales.

Christophe Ancey, Joris Heyman, François Mettra, Hongbo Ma

Bedload transport rate in mountain rivers is highly fluctuating and has strong stochastic behavior even under steady flow conditions. Its stochastic description thus offers deeper insights into its dynamics than the deterministic one. As a random quantity, ...

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 ...

Assessing long-term land-use legacies in subalpine grasslands using a plant-trait based generic modelling framework

Aurélie Thébault

Background: In European mountains, where semi-natural grasslands have high cultural and nature conservation value, land-use legacies from past ploughing are associated with distinct floristic compositions and ecosystem properties. It remains unknown if the ...

Spatio-temporal measurements and analysis of snow depth in a rock face

Michael Lehning

Snow in rock faces plays a key role in the alpine environment for permafrost distribution, snow water storage or runoff in spring. However, a detailed assessment of snow depths in steep rock walls has never been attempted. To understand snow distribution i ...
