Carbon Fluxes and Stocks by Mexican Tropical Forested Wetland Soils: A Critical Review of Its Role for Climate Change Mitigation
forested wetlands carbon pool ecosystem services carbon sequestration
2023/12/15
Wetland soils are important stores of soil carbon (C) in the biosphere, and play an important role in global carbon cycles in the response strategy to climate change. However, there areknowledge gaps ...
Influence of Soil Properties on P Pools and Its Effect on Forest Productivity in Mediterranean Calcareous Soils
calcareous soils Mediterranean ecosystem phosphorus availability phosphorus fractionation semiarid environment sequential extraction
2023/12/11
Although soil phosphorus is essential for vegetation growth it is not always found in labile forms, hampering its absorption by plants, and is limited in forest ecosystems. This study explores soil P ...
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...

2023/12/6
The roles of different tree species and their impacts are key in assessing the dynamics of soil restoration in afforested post-mining sites. The objective of this study was to compare the effect of Sc...
Ecosystem Carbon Stocks and Their Annual Sequestration Rate in Mature Forest Stands on the Mineral Soils of Estonia
forest ecosystem phytocoenosis soil cover organic carbon stock phytomass annual increase
2023/12/4
Mature forest ecosystems are the most considerable reservoir of organic carbon (OC) among terrestrial ecosystems. The effect of soil type on aboveground OC stocks and their annual increases (AI) of ov...
Carbon Pool in Mexican Wetland Soils: Importance of the Environmental Service
wetlands environmental services carbon soil sequestration carbon budgets
2023/11/29
Mexican wetlands are not included in Earth system models around the world, despite being an important carbon store in the wetland soils in the tropics. In this review, five different types of wetlands...
