Evidence for alternative electron sinks to photosynthetic carbon assimilation in the high mountain plant species Ranunculus glacialis
The high mountain plant species Ranunculus glacialis has a low antioxidative scavenging capacity and a low activity of thermal dissipation of excess light energy despite its growth under conditionsExpand

Direct and indirect control by snow cover over decomposition in alpine tundra along a snowmelt gradient
We assessed direct and indirect effects of snow cover on litter decomposition and litter nitrogen release in alpine tundra. Direct effects are driven by the direct influence of snow cover onExpand

Contrasting Diversity Patterns of Crenarchaeal, Bacterial and Fungal Soil Communities in an Alpine Landscape
Background The advent of molecular techniques in microbial ecology has aroused interest in gaining an understanding about the spatial distribution of regional pools of soil microbes and the mainExpand

Ecosystem feedbacks and cascade processes: understanding their role in the responses of Arctic and alpine ecosystems to environmental change
Global environmental change, related to climate change and the deposition of airborne N-containing contaminants, has already resulted in shifts in plant community composition among plant functionalExpand

Rhizodeposition of organic carbon by plants with contrasting traits for resource acquisition: responses to different fertility regimes
Background and aimsRhizodeposition plays an important role in mediating soil nutrient availability in ecosystems. However, owing to methodological difficulties (i.e., narrow zone of soil aroundExpand

Microbial diversity in alpine tundra soils correlates with snow cover dynamics
The temporal and spatial snow cover dynamics is the primary factor controlling the plant communities' composition and biogeochemical cycles in arctic and alpine tundra. However, the relationshipsExpand

The effects of snowpack properties and plant strategies on litter decomposition during winter in subalpine meadows
AimsClimate-induced changes in snow cover are likely to affect cold arctic and alpine ecosystems functioning and major processes such as wintertime plant litter decomposition. However, it remainsExpand

Land use in subalpine grasslands affects nitrogen cycling via changes in plant community and soil microbial uptake dynamics
Summary 1. Nitrogen (N) cycling is a key process determining ecosystem functioning in subalpine grasslands where traditional mowing and manuring are being abandoned. However, the roles of theExpand

Tannin impacts on microbial diversity and the functioning of alpine soils: a multidisciplinary approach.
In alpine ecosystems, tannin-rich-litter decomposition occurs mainly under snow. With global change, variations in snowfall might affect soil temperature and microbial diversity with biogeochemicalExpand

No increase in alpine snowbed productivity in response to experimental lengthening of the growing season.
Climate change effects on snow cover and thermic regime in alpine tundra might lead to a longer growing season, but could also increase risks to plants from spring frost events. Alpine snowbeds, i.e.Expand
