Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Land‐Use Thresholds and Spatial Regulation Oriented Toward Ecosystem Service Supply–Demand Balance: A Case Study of Jiangxi Province

Land Degradation &Development, EarlyView.
ABSTRACT Imbalances between ecosystem service (ES) supply and demand constrain ecological governance and sustainable development. While spatial patterns of these imbalances have been widely studied, less attention has been paid to the land‐use thresholds and regulatory mechanisms needed to maintain ES balance. Using Jiangxi Province as a case study, we

Recent advances in the long-distance transport of sugars by the phloem and consequences on source-sink relations

, 2023
International audienceThe distribution of photoassimilates in the plant relies on the phloem functions from source to sink organs. Phloem sugar transport is regulated by SUC/SUT and SWEET sugar transporters. We observed that deregulation of SUT1 or SUT2

A compartmentation approach to deconstruct ecosystem carbon fluxes of a Moso bamboo forest in subtropical China

Forest Ecosystems
Moso bamboo (Phyllostachys edulis) forests are a vital resource in subtropical China, known for their high carbon (C) sequestration capacity. However, the dynamic processes of C fluxes within each component (canopy, culm, and soil) and their individual ...

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

Laser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

Temporal Accumulation and Partitioning of Mineral Nutrients in Developing Macadamia Fruit

Horticulturae
This study quantified nutrient accumulation and partitioning among the kernel, shell, husk, rachis, and leaves during fruit development in three macadamia cultivars. Racemes and leaves were sampled at biweekly intervals until kernel maturity.

Property Rights Entrepreneurship: The Drive for Product, Asset, and Resource Excludability

Managerial and Decision Economics, EarlyView.
ABSTRACT Property rights are foundational to market economies, and entrepreneurial activity depends heavily on the excludability afforded by property rights. Yet, the role of entrepreneurs in shaping the evolution of property rights has been so thoroughly taken for granted that it often vanishes from analyses.

Root-to-shoot signaling positively mediates source-sink relation in late growth stages in diploid and tetraploid wheat

BMC Plant Biology
Non-hydraulic root source signaling (nHRS) is a unique positive response to soil drying in the regulation of plant growth and development. However, it is unclear how the nHRS mediates the tradeoff between source and sink at the late growth stages and its

Nitrogen and potassium fertilization regulates source–sink relations, biomass allocation, and nutrient dynamics for industrial biomass production in cassava (

Industrial Crops and Products
Cassava fertilization primarily targets the enhancement of fresh storage-root yield, while fresh stem-and-leaf yield, source-sink allocation, and nutrient balances are often overlooked.

Hydro‐Mechanical Modelling of Gas Migration in Bentonite: Formulation and Laboratory‐Scale Validation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Gas generation and migration in bentonite buffer materials are critical processes affecting the performance of deep geological repositories for radioactive waste. This study presents a new hydro‐mechanical formulation for simulating gas migration in saturated, compacted bentonite, with particular emphasis on the role of non‐uniform stress ...
