Patterns and Internal Stability of Carbon, Nitrogen, and Phosphorus in Soils and Soil Microbial Biomass in Terrestrial Ecosystems in China: A Data Synthesis
spatial pattern C:N:P vegetation types nutrient limitation homeostasis
2023/12/11
Inspired by the strict constraint ratio (relatively low variability) between carbon (C), nitrogen (N), and phosphorus (P) in global soils and soil microbial biomass, our study explores the biogeograph...
The Soil Aggregates and Associated Organic Carbon across the Greater Khingan Mountains: Spatial Patterns and Impacting Factors
Greater Khingan Mountains forest soils soil aggregates soil organic carbon spatial variation
2023/12/1
1) Background: The preservation of soil organic carbon (SOC) by soil aggregates (SA) is a key mechanism for the stability of the soil carbon (C) pool. (2) Methods: Soil samples were collected at a 0–2...
Monthly Dynamical Patterns of Nitrogen and Phosphorus Resorption Efficiencies and C:N:P Stoichiometric Ratios in Castanopsis carlesii (Hemsl.) Hayata and Cunninghamia lanceolata (Lamb.) Hook. Plantations

Integrative analysis from the epigenome to translatome uncovers patterns of dominant nuclear regulation during transient stress
epigenome dominant nuclear regulation transient stress post-transcriptional gene regulation hypoxia reveals
2024/2/29
Gene regulation is modulated from chromatin to translation. To better understand the integration of nuclear and cytoplasmic gene regulatory dynamics, we performed a multi-omic survey of the epigenome ...
