Abstract. For more than two decades, research groups in hydrology, ecology, soil science, and biogeochemistry have performed cryogenic water extractions (CWEs) for the analysis of δ2H δ18O water. Recent studies shown that extraction conditions (time, temperature, vacuum) along with physicochemical properties may affect extracted isotope composition. Here we present results from first worldwide round robin laboratory intercomparison. We test null hypothesis that, identical soils, standards,...
Abstract Biochar application to soil shows promise for enhancing properties, increasing crop yields, improving water retention, and promoting carbon sequestration. While the direct effects of biochar on properties have been studied some extent, overall impact ecosystem balance remains uncertain, as field lab studies typically do not account interactions with vegetation. The LiDELS (LiBry-DETECT Layer Scheme) model offers a process-based approach assess these soil-vegetation potential...

The local climate in cities differs from the one rural areas, most prominently characterized by increased surface and air temperatures, known as “(surface) urban heat island”. As has changed continues to change all areas of world, question arises whether effects that are noticeable “homemade”, or some them originate global regional scale changes. Identifying locally induced changes meteorological parameters is especially relevant for development adaptation mitigation measures. This study...

Abstract Coastal salt marshes have an important role in climate change adaptation and mitigation. Direct indirect responses to warming are expected vary along the marsh elevation gradient, making ecosystem at this marine‐terrestrial ecotone uncertain. The Marsh Ecosystem Response Increased Temperatures (MERIT) experiment was established 2018 on North Sea coast of Germany. Experimental plots evenly distributed over three elevational zones (pioneer, low marsh, high marsh) include temperature...
For a typical encroacher tree of the thornbush savanna, we studied responses water consumption to changes in soil availability within 80 cm depth, vapor pressure deficit (VPD), and global radiation. Therefore, monitored sap velocities Senegalia mellifera trees over 2 years maximum 20 stems (6–15 plant individuals) per measurement period on site central Namibia. this water-restricted ecosystem aimed understand role an dynamics potential groundwater recharge. At day-to-day scale, was primary...
<div> <p>For the understanding of carbon cycle in terrestrial ecosystems as well plant stress responses to drought and hypoxia, study fine root dynamics plays an important role. However, number relevant studies is still limited, which may be due, among other things, high costs commercial minirhizotron systems. Here, we present affordable (<500 €) fully automated system, utilizing new developments low-cost electronics 3D-printing. The camera...
<p>Facing the consequences of climate change like sea level rise and an intensified storminess, salt marshes will play increasingly important role in future coastal protection. The vegetation contributes significantly to protection function as plants reduce erosion act obstruction hydrodynamic forces resulting wave attenutation. Yet, how other global factors such higher temperatures affect their potential protect our coasts against high intensities, e.g. during storm surges, is...
Temperate hardwood floodplain forests (HFF) are highly heterogeneous and productive ecosystems threatened by anthropogenic influence effects of global warming. Quercus robur (oaks) Ulmus laevis (elms) acknowledged in literature as the two highest second aboveground carbon biomass stores along lower middle Elbe floodplain. Both species adapted to hydrological fluctuations soils. However, Central Europe, these  are IPCC (2022) expected increase streamflow drought, soil moisture...
