Tree‐ and stand‐scale variability of xylem water stable isotope signatures in mature beech, oak and spruce

Fabian Bernhard, Marius G. Floriancic, Kerstin Treydte, Arthur Gessler, more

In ecohydrology, water isotopologues are used to assess potential sources of root water uptake by comparing xylem water signatures with source water signatures. Such comparisons are affected by the variability and uncertainty of the isotope signatures of plant water and water sources. The tree‐scale and stand‐scale variabilities of the isotope signatures in stem xylem water are often unknown but are...

Finding balance: Tree‐ring isotopes differentiate between acclimation and stress‐induced imbalance in a long‐term irrigation experiment

Valentina Vitali, Philipp Schuler, Meisha Holloway‐Phillips, Petra D'Odorico, more

Global Change Biology > 30 > 3 > n/a - n/a

Scots pine (Pinus sylvestris L.) is a common European tree species, and understanding its acclimation to the rapidly changing climate through physiological, biochemical or structural adjustments is vital for predicting future growth. We investigated a long‐term irrigation experiment at a naturally dry forest in Switzerland, comparing Scots pine trees that have been continuously irrigated for 17 years...

Occurrence and erosion susceptibility of German Pelosols and international equivalents

Simon Scheper, Katrin Meusburger, Pasquale Borrelli, Panos Panagos, more

Journal of Plant Nutrition and Soil Science > 185 > 6 > 821 - 835

Background Pelosols are the Soil of the Year 2022 in Germany, Austria and Switzerland. They represent soils with a high clay content (≥45%) in the diagnostic P horizon. Pelosols are nutrient‐rich, have a strong capacity for swelling and shrinking, have a challenging water balance with a high portion of nonplant available water and are affected by high traction. Such special characteristics make them...

Soil–plant interactions modulated water availability of Swiss forests during the 2015 and 2018 droughts

Katrin Meusburger, Volodymyr Trotsiuk, Paul Schmidt‐Walter, Andri Baltensweiler, more

Global Change Biology > 28 > 20 > 5928 - 5944

Central Europe has been experiencing unprecedented droughts during the last decades, stressing the decrease in tree water availability. However, the assessment of physiological drought stress is challenging, and feedback between soil and vegetation is often omitted because of scarce belowground data. Here we aimed to model Swiss forests' water availability during the 2015 and 2018 droughts by implementing...

Soil fauna drives vertical redistribution of soil organic carbon in a long‐term irrigated dry pine forest

Claudia Guidi, Beat Frey, Ivano Brunner, Katrin Meusburger, more

Global Change Biology > 28 > 9 > 3145 - 3160

Summer droughts strongly affect soil organic carbon (SOC) cycling, but net effects on SOC storage are unclear as drought affects both C inputs and outputs from soils. Here, we explored the overlooked role of soil fauna on SOC storage in forests, hypothesizing that soil faunal activity is particularly drought‐sensitive, thereby reducing litter incorporation into the mineral soil and, eventually, long‐term...

Global maps of soil temperature

Jonas J. Lembrechts, Johan Hoogen, Juha Aalto, Michael B. Ashcroft, more

Global Change Biology > 28 > 9 > 3110 - 3144

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic...

Drought reduces water uptake in beech from the drying topsoil, but no compensatory uptake occurs from deeper soil layers

Arthur Gessler, Lukas Bächli, Elham Rouholahnejad Freund, Kerstin Treydte, more

New Phytologist > 233 > 1 > 194 - 206

The intensity and frequency of droughts events are projected to increase in future with expected adverse effects for forests. Thus, information on the dynamics of tree water uptake from different soil layers during and after drought is crucial. We applied an in situ water isotopologue monitoring system to determine the oxygen isotope composition in soil and xylem water of European beech with a...

Drone‐based physiological index reveals long‐term acclimation and drought stress responses in trees

Petra D'Odorico, Leonie Schönbeck, Valentina Vitali, Katrin Meusburger, more

Plant, Cell & Environment > 44 > 11 > 3552 - 3570

Monitoring early tree physiological responses to drought is key to understanding progressive impacts of drought on forests and identifying resilient species. We combined drone‐based multispectral remote sensing with measurements of tree physiology and environmental parameters over two growing seasons in a 100‐y‐old Pinus sylvestris forest subject to 17‐y of precipitation manipulation. Our goal was...

Drought alters the carbon footprint of trees in soils—tracking the spatio‐temporal fate of ¹³C‐labelled assimilates in the soil of an old‐growth pine forest

Decai Gao, Jobin Joseph, Roland A Werner, Ivano Brunner, more

Global Change Biology > 27 > 11 > 2491 - 2506

Above and belowground compartments in ecosystems are closely coupled on daily to annual timescales. In mature forests, this interlinkage and how it is impacted by drought is still poorly understood. Here, we pulse‐labelled 100‐year‐old trees with ¹³CO₂ within a 15‐year‐long irrigation experiment in a naturally dry pine forest to quantify how drought regime affects the transfer and use of assimilates...

Determinants of legacy effects in pine trees – implications from an irrigation‐stop experiment

Roman Zweifel, Sophia Etzold, Frank Sterck, Arthur Gessler, more

New Phytologist > 227 > 4 > 1081 - 1096

Tree responses to altered water availability range from immediate (e.g. stomatal regulation) to delayed (e.g. crown size adjustment). The interplay of the different response times and processes, and their effects on long‐term whole‐tree performance, however, is hardly understood. Here we investigated legacy effects on structures and functions of mature Scots pine in a dry inner‐Alpine Swiss valley...

Documenting soil redistribution on livestock‐poached pasture using caesium‐134 and cobalt‐60 as tracers

Philip Greenwood, Katrin Meusburger

Land Degradation & Development > 30 > 3 > 315 - 327

Poaching is caused by the excessive trampling of soil and vegetation by herd animals and is prevalent in intensively managed grasslands. It is viewed as detrimental to soil fertility, has the potential to contribute to soil erosion, and thus represents a form of land degradation that is unsustainable. Attempts to document sediment redistribution by poaching have been hampered by a lack of techniques...

Filling the European blank spot—Swiss soil erodibility assessment with topsoil samples

Simon Schmidt, Cristiano Ballabio, Christine Alewell, Panos Panagos, more

Journal of Plant Nutrition and Soil Science > 181 > 5 > 737 - 748

Soil erodibility, commonly expressed as the K‐factor in USLE‐type erosion models, is a crucial parameter for determining soil loss rates. However, a national soil erodibility map based on measured soil properties did so far not exist for Switzerland. As an EU non‐member state, Switzerland was not included in previous soil mapping programs such as the Land Use/Cover Area frame Survey (LUCAS). However,...

Object‐oriented soil erosion modelling: A possible paradigm shift from potential to actual risk assessments in agricultural environments

Pasquale Borrelli, Katrin Meusburger, Cristiano Ballabio, Panos Panagos, more

Land Degradation & Development > 29 > 4 > 1270 - 1281

Over the last 2 decades, geospatial technologies such as Geographic Information System and spatial interpolation methods have facilitated the development of increasingly accurate spatially explicit assessments of soil erosion. Despite these advances, current modelling approaches rest on (a) an insufficient definition of the proportion of arable land that is exploited for crop production and (b) a...

Lionel Mabit, Max Gibbs, Modou Mbaye, Katrin Meusburger, more

Geoderma > 2018 > 316 > C > 19-26

In recent years, Compound Specific Stable Isotope (CSSI) techniques have enabled promising new tracers to track land-use-specific sediment sources. However, empirical data exploring the technique, particularly under controlled conditions, is still scarce. Hence, the main goal of this study is to explore the suitability of CSSI to identify sediment sources under different land use in the small agricultural...

Fate of 137Cs, 90Sr and 239+240Pu in soil profiles at a water recharge site in Basel, Switzerland

Johannes Abraham, Katrin Meusburger, Judith Kobler Waldis, Michael E. Ketterer, more

Journal of Environmental Radioactivity > 2018 > 182 > C > 85-94

An important process in the production of drinking water is the recharge of the withdrawn ground water with river water at protected recharge fields. While it is well known that undisturbed soils are efficiently filtering and adsorbing radionuclides, the goal of this study was to investigate their behaviour in an artificial recharge site that may receive rapid and additional input of radionuclides...

Panos Panagos, Cristiano Ballabio, Katrin Meusburger, Jonathan Spinoni, more

Journal of Hydrology > 2017 > 548 > C > 251-262

The policy requests to develop trends in soil erosion changes can be responded developing modelling scenarios of the two most dynamic factors in soil erosion, i.e. rainfall erosivity and land cover change. The recently developed Rainfall Erosivity Database at European Scale (REDES) and a statistical approach used to spatially interpolate rainfall erosivity data have the potential to become useful...

Modelling Hot Spots of Soil Loss by Wind Erosion (SoLoWind) in Western Saxony, Germany

Simon Schmidt, Katrin Meusburger, Tomás Figueiredo, Christine Alewell

Land Degradation & Development > 28 > 3 > 1100 - 1112

While it needs yet to be assessed whether or not wind erosion in Western Saxony is a major point of concern regarding land degradation and fertility, it has already been recognized that considerable off‐site effects of wind erosion in the adjacent regions of Saxony‐Anhalt and Brandenburg are connected to the spread of herbicides, pesticides and dust. So far, no wind erosion assessment for Western...

Mapping monthly rainfall erosivity in Europe

Cristiano Ballabio, Pasquale Borrelli, Jonathan Spinoni, Katrin Meusburger, more

Science of The Total Environment > 2017 > 579 > C > 1298-1315

Rainfall erosivity as a dynamic factor of soil loss by water erosion is modelled intra-annually for the first time at European scale. The development of Rainfall Erosivity Database at European Scale (REDES) and its 2015 update with the extension to monthly component allowed to develop monthly and seasonal R-factor maps and assess rainfall erosivity both spatially and temporally. During winter months,...

Modelling Deposition and Erosion rates with RadioNuclides (MODERN) – Part 2: A comparison of different models to convert 239+240Pu inventories into soil redistribution rates at unploughed sites

Laura Arata, Christine Alewell, Elena Frenkel, Annette A’Campo-Neuen, more

Journal of Environmental Radioactivity > 2016 > 162-163 > C > 97-106

Sheet erosion is one of the major threats to alpine soils. To quantify its role and impact in the degradation processes of alpine grasslands, the application of Fallout Radionuclides (FRN) showed very promising results. The specific characteristics of plutonium 239 + 240 (^239+240Pu), such as the homogeneous fallout distribution, the long half-life and the cost and time effective measurements make...

A multi-radionuclide approach to evaluate the suitability of 239+240Pu as soil erosion tracer

Katrin Meusburger, Lionel Mabit, Michael Ketterer, Ji-Hyung Park, more

Science of The Total Environment > 2016 > 566-567 > C > 1489-1499

Fallout radionuclides have been used successfully worldwide as tracers for soil erosion, but relatively few studies exploit the full potential of plutonium (Pu) isotopes. Hence, this study aims to explore the suitability of the plutonium isotopes ²³⁹Pu and ²⁴⁰Pu as a method to assess soil erosion magnitude by comparison to more established fallout radionuclides such as ¹³⁷Cs and ²¹⁰Pb_ex. As test area...
