All plant species reach a low temperature range limit when either low temperature extremes exceed their freezing tolerance or when their metabolism becomes too restricted. In this study, we explore the ultimate thermal limit of plant tissue formation exemplified by a plant species that seemingly grows through snow. By a combination of studies in alpine snowbeds and under controlled environmental conditions, we demonstrate and quantify that the clonal herb Soldanella pusilla (Primulaceae) does in...

Abstract Increased atmospheric nitrogen (N) deposition is driving nutrient imbalances, soil acidification, biodiversity losses and the long-term reduction in stability of sensitive ecosystems which previously had limited N. In this study, we analysed the concentrations of seven different N compounds in precipitation and in the air at 34 sites across Switzerland. We calculated the N deposition by precipitation (bulk deposition) and applied the inferential method to derive dry deposition (gases, a...

Climate change is particularly apparent in many mountainous regions, with warming rates of more than twice the global average being reported for the European Alps. As a result, the probability of climate extremes has increased and is expected to rise further. In an earlier study, we looked into immediate impacts of experimentally imposed heat waves in alpine grassland, and found that these systems were able to cope with heat as long as enough water was available. However, concomitant drought led...

Schmetterlinge bilden mit uber 150 000 Arten eine der grossten Insektenordnungen der Welt. In der Schweiz kommen rund 3700 Arten vor, davon sind 182 Arten echte Tagfalter. Wir konnten auf der Furka in kurzer Zeit 27 Tagfalterarten (15%) und 77 nachtaktive Arten feststellen. Zudem wurden 22 Kleinschmetterlingsarten beobachtet.

Alpine ecosystems are, similar to arctic ecosystems, characterized by a very long snow season. Previous studies investigating arctic or alpine ecosystems have shown that winter CO2 effluxes can dominate the annual balance and that the timing and duration of the snow cover plays a crucial role for plant growth and phenology and might also influence the growing season ecosystem CO2 strength and dynamics. The objective of this study was to analyze seasonal and annual CO2 balances of a grassland sit...

Shrub encroachment is one of the main consequences of abandonment of montane grassland. Higher surface roughness of shrubs leads to stronger aerodynamic coupling. This should increase evapotranspiration (ET), but lower surface temperatures (due to higher ET and reduced aerodynamic resistance) could counter this effect. We explored this question by employing weighable lysimeters in adjacent grass- and shrubland understorey, and by measuring canopy transpiration in Alnus with sap flow sensors at 1...

Die Gewasser zwischen Gletschereis und Bergbachen sind zwar meist eisig kalt, die Lebensbedingungen sind aber fur Gewasserbewohner gleichformiger als fur Landorganismen. Wahrend der vier Feldtage fanden wir rund 90 Kleintierarten und 215 Arten von Kieselalgen. Diese widerspiegeln die kleinraumige Vielfalt der unterschiedlichen Gewassertypen. Bei den artenreichen Kocherfliegen wurde die Larve einer Art gefunden, die bisher nur als erwachsenes Tier bekannt war. Bei den Kieselalgen gelangen zwei Er...

Plant growth in cold climates is not limited by carbon assimilation (source activity) but rather by reduced carbon investment into new tissues (sink limitation). It has been hypothesized that all cold-adapted plants face similar growth constraints at low temperature mainly associated with the formation of new tissues. To explore the thermal limitation of plant tissue formation, we studied root growth and anatomical root tissue characteristics in four cold-adapted alpine species (Ranunculus glaci...
