Interannual variation in evapotranspiration in an urban forest reserve with respect to drought

open access: yesFrontiers in Forests and Global Change, 2023
IntroductionA warming global climate is expected to perturb the hydrological cycle, resulting in deviations in both frequency and duration of drought and thus being hypothesized to lead to interannual variation in evapotranspiration (ET).

Economics of soil and water conservation [PDF]

open access: yes, 2003
The Ethiopian highlands, inhabited by the vast majority of the Ethiopian human and livestock populations, are under continuous threat from soil erosion. Land degradation induced by soil erosion is considered to be among the major factors responsible for ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

The effect of modified polymer on the change rule of physical properties of different gradation coal gangue

open access: yesScientific Reports
In this study, in order to improve the water retention of coal gangue matrix and accelerate the recovery of frozen soil layer in mining area, three different particle size gradations of coal gangue and modified polymer SAP (0.0, 0.1, 0.2, 0.3, 0.4%) were

Spatiotemporal Distribution Characteristics of Soil Organic Carbon and Its Influencing Factors in the Loess Plateau

open access: yesAgronomy
Soil organic carbon (SOC) constitutes the largest terrestrial carbon pool and plays a crucial role in climate regulation, soil fertility, and ecosystem functioning. Understanding its spatiotemporal dynamics is particularly important in semi-arid regions,

Key indicators describing the evolution of landslides in the Zhuoshui River Basin caused by the Chi-Chi earthquake in Taiwan

open access: yesGeomatics, Natural Hazards & Risk, 2022
This study selected the landslide caused by the 1999 Chi-Chi earthquake, which occurred once in a century, and analysed the spatio-temporal distribution of landslide evolution in the basin through the concavity, slope, and sediment delivery ratio (SDR ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The trade-off between soil water recovery and nitrate leaching following the orchard-to-cropland conversion in the Chinese Loess Plateau

open access: yesScientific Reports
A large-scale conversion of apple orchards into farmland has occurred in the tableland region of the Chinese Loess Plateau due to the aging of apple trees and the increase in pests and diseases.

Mapping soil degradation using remote sensing data and ancillary data: South-East Moravia, Czech Republic

open access: yesEuropean Journal of Remote Sensing, 2019
Data on the real extent of soil that is degraded by erosion represent important information for the purposes of conservation policy. However, this type of data is rarely available for large areas.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
