Summary Tree responses to altered water availability range from immediate (e.g. stomatal regulation) delayed crown size adjustment). The interplay of the different response times and processes, their effects on long‐term whole‐tree performance, however, is hardly understood. Here we investigated legacy structures functions mature Scots pine in a dry inner‐Alpine Swiss valley after stopping an 11‐yr lasting irrigation treatment. Measured ecophysiological time series were analysed interpreted...
Abstract The European Alps are highly rich in species, but their future may be threatened by ongoing changes human land use and climate. Here, we reconstructed vegetation, temperature, impact livestock over the past ~12,000 years from Lake Sulsseewli, based on sedimentary ancient plant mammal DNA, pollen, spores, chironomids, microcharcoal. We assembled a highly-complete local DNA reference library (PhyloAlps, 3923 taxa), used this to obtain an exceptionally sed aDNA record of 366 taxa....
Abstract Climate change exposes ecosystems to strong and rapid changes in their environmental boundary conditions mainly due the altered temperature precipitation patterns. It is still poorly understood how fast interlinked ecosystem processes respond conditions, if these responses occur gradually or suddenly when thresholds are exceeded, patterns of will reach a stable state. We conducted an irrigation experiment Pfynwald, Switzerland from 2003–2018. A naturally dry Scots pine ( Pinus...
In xeric environments, an increase in drought is related to reduced forest productivity and enhanced mortality. However, predictions of future development remain difficult as the mechanisms underlying responses mature trees long-term variations water availability are not well understood. Here, we aimed compare adjustments radial growth morphological needle shoot traits Scots pine (Pinus sylvestris L.) growing along open channels with those control under naturally dry conditions at three...
Adjustment mechanisms of trees to changes in soil-water availability over long periods are poorly understood, but crucial improve estimates forest development a changing climate. We compared mature Scots pine (Pinus sylvestris) and European larch (Larix decidua) growing along water-permeable channels (irrigated) under natural conditions (control) at three sites inner-Alpine dry valleys. At two sites, the irrigation had been stopped 1980s. combined measurements basal area increment (BAI),...
Vegetation shift in Scots pine forests the Valais accelerated by large disturbances In past dozen years, several studies have concluded a vegetation from to oak (pubescent and sessile) low elevated zones of Valais. It is, however, not fully clear which way such actually occurs on processes would be based. Two studies, one tree demography intact Pfynwald other regeneration Leuk forest fire patch, serve discuss different aspects oak. The stands consist 67% pines 14% oaks. Regenerating trees...
On 2 June 2023, the first Research Symposium SNP+ took place in Zernez, Switzerland, at headquarters of Swiss National Park (SNP). The symposium aimed to bring together active researchers from various scientific fields relevant work Park, Regional Nature Biosfera Val Müstair (BVM), and overarching UNESCO Biosphere Reserve Engiadina (UBEVM) â all represented here by SNP+. Addressing subjects bridging gap between strict nature preservation cultivated landscape areas, importance ongoing...
