Bamboo charcoal application altered the mineralization process of soil organic carbon in different succession stages of karst forest land

Frontiers in Environmental Science
Introduction: As a soil amendment, Bamboo charcoal helps to contributes to the improvement of soil carbon sequestration, but its effect on the accumulation and transformation of different soil organic carbon in soil of karst forests is not clear.Methods:

The structure and soil characteristics of a Pinus tabuliformis planted forest after 60 years of natural development in North China

Silva Fennica, 2017
This study evaluated the transformation of a Carrière forest into a near-natural forest after 60 years of natural development. The structure and soil characteristics of planted forest, the near-natural forest (coniferous-broadleaved mixed forest ...

Aspects of precommercial thinning [PDF]

, 2005
Precommercial thinning (PCT) in young forests in Sweden has been an important part of the silvicultural system since the 1950s. However, the annual area treated with PCT has decreased since the 1990s. At the same time the relative cost of PCT compared to

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Enhanced CO2 Response and Aging‐Related Dynamics Drive a Greater Leaf Area Index Increase in China's Planted Forests in Comparison to Natural Forests

Geophysical Research Letters
China's forests have experienced a notable increase in leaf area, driven by planted forest expansion and natural forest conservation. However, how planted and natural forests respond differently to environmental changes remains unclear.

Integration of Landsat–Sentinel Time Series and Flowering Phenology for Mapping Planted Forests and Distinguishing Tree Crops

Remote Sensing
Planted forests are increasingly promoted to meet rising demand for forest products and restore degraded lands, but their extent and ecological implications are often misrepresented because tree crops (e.g., orchards, plantation agriculture) exhibit ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Conservation biological control in forest: A case study with the pine processionary moth

Biological Control
In forest ecosystems, the damage caused to trees by insect pests is increasing as a result of global change. Classical biological control has proven effective in managing exotic pests by introducing natural enemies from the pest’s native range.
