Climate Change and Reduction of Soil Organic Layer Thickness Increases Drought Risk in Mountain Forests of the Northern Alps

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background On ca. 10% of the forested sites in the Bavarian Alps (Germany) mountain, forest soils (so‐called folic histosols) are characterized by thick organic layers overlying poorly weathered calcareous parent material. Aim These organic layers play a critical role in releasing water and nutrients for vegetation, yet they are also sensitive

Temperature Sensitivity of the Humus Form Tangel

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Tangel is an important humus form in mountain forests, particularly in areas of carbonate rock. To gain an initial understanding of its sensitivity to rising temperatures, a respiration experiment was conducted. The derived Q10 values (3.35–3.36) are comparatively high in relation to values reported in the literature, indicating that Tangel is

Engineered Flooring from Low-Density Plantation Hardwood: Evaluation of Long-Term In-Service Trials [PDF]

The use of short-rotation hardwood plantation species has been perceived to be unsuitable for flooring until recently, due to the lower densities. This study assesses the performance of a low-density plantation hardwood species, Eucalyptus nitens in ...

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

Journal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Elevator dynamic monitoring and early warning system based on machine learning algorithm

IET Networks, EarlyView., 2022
In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

LAMINATED WOOD AND CHIPBOARD FLOORING TOWARDS ENVIRONMENTALLY FRIENDLY ALTERNATIVES

, 2019
The article presents a series of tests conducted over a sample of chipboard and wood flooring in order to compare some physical and chemical characteristics of these materials with other alternative raw materials that may replace wood.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Application of Organic Superabsorbent Cellulosic Polymers (OSCPs) and Cyanobacteria on Reduction of Aeolian Losses

Land Degradation &Development, EarlyView.
ABSTRACT Establishing biocrusts on sandy surfaces in harsh desert environments presents significant challenges due to extreme ecological conditions. To address these challenges, this study examined the effects of two organic superabsorbent cellulosic polymers (OSCPs)—carboxymethyl cellulose (CMC) and guar gum (GUA)—on the establishment of ...

Differences in Dust Emission and Near‐Surface Transport Patterns Among Three Surface Substrate Types

Land Degradation &Development, EarlyView.
ABSTRACT Soil wind erosion is a major driver of atmospheric dust emissions and land degradation. Many studies have examined dust release from different substrates, but differences in methods and units still limit quantitative understanding of how surface conditions and wind jointly control dust emission and near‐surface transport. A closed‐circuit wind

Integrated Prediction and Analysis of Soil Erosion and Soil Organic Carbon Loss in the Dayekou Watershed, Qilian Mountains

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion poses a critical threat to ecological security in mountain watersheds worldwide. Predicting its dynamics and associated soil organic carbon (SOC) loss remains an ongoing challenge during the 21st century due to complex interactions among climate, land use, and topography.
