Most trees form symbioses with ectomycorrhizal fungi (EMF) which influence access to growth-limiting soil resources. Mesocosm experiments repeatedly show that EMF species differentially affect plant development, yet whether these effects ripple up the growth of entire forests remains unknown. Here we tested composition and functional genes relative variation in well-known drivers tree by combining paired molecular surveys high-resolution forest inventory data across 15 European countries. We...
Abstract Forest soils harbor hyper-diverse microbial communities which fundamentally regulate carbon and nutrient cycling across the globe. Directly testing hypotheses on how microbiome diversity is linked to forest storage has been difficult, due a lack of paired data in situ observations accumulation storage. Here, we investigated relationship between soil microbiomes 238 inventory plots spanning 15 European countries. We show that composition fungal, but not bacterial, species tightly...
Despite reduction of nitrogen emissions, deposition in German forests remain high. Eutrophication ecosystems thus remains an important issue scientific and socio-political interest. Here we analyse data from 78 intensive forest monitoring (Level II) sites operated by the research institutes federal states as part ICP Forests network (International Co-operative Programme on Assessment Monitoring Air Pollution Effects Forests). In 2013-2022 period, mean annual bulk open field (inorganic +...
The input of nitrogen (N) into forests through atmospheric deposition has been determined for the main forest types within ICP Forests Level II monitoring network and Swedish Throughfall Monitoring Network (SWETHRO) since 1990s from measured concentrations in continuously collected precipitation (bulk deposition) throughfall (below tree canopy) samples. Recently, aggregated data sets have created, containing gap-filled monthly annual bulk depositions (including stemflow beech stands) more...
A reliable quantification of total inorganic nitrogen (TIN) deposition to forests is required for the evaluation ecological effects TIN inputs and monitor success clean-air policy. As direct measurements are scarce, different modelling approaches have been developed estimate forests. Three common methods (i) "canopy budget model", (ii) "inferential method" (iii) "emission based estimates" using a chemical transport model. Previous studies reported considerable site-specific differences...
Atmospheric nitrogen and sulfur deposition is an important effect of atmospheric pollution may affect forest ecosystems positively, for example enhancing tree growth, or negatively, causing acidification, eutrophication, cation depletion in soil nutritional imbalances trees. To assess design measures to reduce the negative impacts deposition, a good estimate amount needed, either by direct measurement modeling. In order evaluate precision both approaches identify possible improvements, we...
We investigate recently proposed measures for the statistical dependence of systems with complex dynamical behavior. consider appropriate model systems, to ensure that influences individual properties are excluded. demonstrate it is indeed possible obtain nontrivial directional information, but we also argue interpretation this information difficult.
Foliar nutrient concentrations, contents, and ratios are important indicators for the nutritional status of trees. They depend on availability nutrients uptake capacities trees, which controlled by forest structure, soil climate condition. Consequently, accounting conditions can aid interpretation foliar chemistry measurements. We applied a moving-window approach to identify effects atmospheric temperature precipitation tree nutrition at different time intervals based data collected...
We generalize the method of surrogate data testing for nonlinearity in time series to case that are sampled with uneven intervals. The null hypothesis will be have been generated by a linear stochastic process, possibly rescaled, and at times chosen independently from generating process. their properties specified Lomb periodogram. inversion problem is solved combinatorial optimization.

Introduction Nitrogen (N) gradient studies in some cases use N deposition throughfall as measure of to forests. For evaluating critical loads N, however, information on total is required, i.e., the sum estimates dry, wet and occult deposition. Methods The present paper collects a number Europe where were compared different forest types. From this dataset function was derived which allows estimate from Results At low values, proportion canopy uptake high thus underestimation by needs be...
Copper is an essential chemical element for life as it a part of prosthetic groups enzymes including super oxide dismutase and cytochrome c oxidase; however, also toxic at high concentrations. Here, we present the trade-off copper availability growth inhibition common host used copper-dependent protein production, Pichia pastoris. At concentrations ranging from 0.1 mM (6.35 mg/L) to 2 (127 mg/L), rates 0.25 h−1 0.16 were observed with uptake 20 mgcopper/gCDW. The intracellular content was...
