Using Model Analysis to Unveil Hidden Patterns in Tropical Forest Structures

Frontiers in Ecology and Evolution, 2021
When ordinating plots of tropical rain forests using stand-level structural attributes such as biomass, basal area and the number of trees in different size classes, two patterns often emerge: a gradient from poorly to highly stocked plots and high ...

Deriving Tree Size Distributions of Tropical Forests from Lidar

Remote Sensing, 2021
Remote sensing is an important tool to monitor forests to rapidly detect changes due to global change and other threats. Here, we present a novel methodology to infer the tree size distribution from light detection and ranging (lidar) measurements.

Retention of harvest residues promotes the accumulation of topsoil organic carbon by increasing particulate organic carbon in a Chinese fir plantation

Forest Ecosystems
Background: As commonly used harvest residue management practices in subtropical plantations, stem only harvesting (SOH) and whole tree harvesting (WTH) are expected to affect soil organic carbon (SOC) content.

PM2.5 Concentration Differences between Various Forest Types and Its Correlation with Forest Structure

Atmosphere, 2015
The Plain Forestation Project is an important measure designed to alleviate air pollution in Beijing, the capital of China. Ten commonly cultivated forest types of the Plain Forestation Project were studied at three growth stages of leaves.

On the Estimation of Forest Vertical Structure From Multibaseline Polarimetric SAR Data

, 2012
Forest characterization and biomass estimation by means of remote sensing systems are nowadays “hot topics” within the remote sensing community, given their importance in the terrestrial carbon budget. In fact, forest vertical structure is a key variable

Liming enhances soil priming effect in Chinese fir plantation induced by glycine rather than glucose and oxalic acid

Geoderma
Liming is a widely adopted strategy to mitigate soil acidification and enhance forest productivity. However, the extent to which liming modulates forest soil priming effects, particularly those induced by distinct root exudate types, remains poorly ...

Dynamic Effects of Structure-Based Forest Management on Stand Spatial Structure in a Platycladus orientalis Plantation

, 2022
Structure-based forest management (SBFM) is a method for improving forest structure and quality based on nearest-neighbor analysis. Stand spatial structure directly affects the health and stability of forest ecosystems. Research on the effects of SBFM on

Boreal forest biomass classification with TanDEM-X

, 2012
High spatial resolution X-band interferometric SAR data from the TanDEM-X, in the operational DEM generation mode, are sensitive to forest structure and can therefore be used for thematic boreal forest classification of forest environments.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
