Components of respiration and their temperature sensitivity in four reconstructed soils

Scientific Reports, 2022
Seasonal changes characteristics in the respiration of four reconstructed soil masses in a barren gravel land were monitored. The results showed that (1) Respiration and heterotrophic respiration of the four reconstructed soils with added meteorite ...

The significance of organic carbon and nutrient export from peatland-dominated landscapes subject to disturbance, a stoichiometric perspective [PDF]

, 2009
The terrestrial-aquatic interface is a crucial environment in which to consider the fate of exported terrestrial carbon in the aquatic system. Here the fate of dissolved organic carbon (DOC) may be controlled by nutrient availability.

Phosphate Resupply Differentially Impacts the Shoot and Root Proteomes of Arabidopsis thaliana Seedlings

Plant, Cell &Environment, Volume 49, Issue 3, Page 1598-1616, March 2026.
ABSTRACT Phosphate (Pi) is an essential macronutrient for plant development that is often limited in soil. Plants have evolved dynamic biochemical, physiological and morphological adaptations to cope with Pi deficiency, known as the Pi starvation response (PSR).

The Role of Microbial Community Composition in Controlling Soil Respiration Responses to Temperature. [PDF]

PLoS ONE, 2016
Rising global temperatures may increase the rates of soil organic matter decomposition by heterotrophic microorganisms, potentially accelerating climate change further by releasing additional carbon dioxide (CO2) to the atmosphere.

Hump‐Shaped Relationship Between Microbial Carbon Use‐Efficiency and Soil Organic Carbon in Alpine Grasslands

Advanced Science, Volume 13, Issue 8, 9 February 2026.
On the Qinghai–Tibetan Plateau, microbial carbon use efficiency (CUE) peaks at intermediate soil organic carbon levels and declines thereafter. In carbon‐rich soils, the formation of stable mineral‐associated organic carbon is decoupled from microbial CUE.

The Impact of Water Content on Sources of Heterotrophic Soil Respiration [PDF]

Forests, 2017
Heterotrophic respiration (RH) is a major flux of CO2 from forest ecosystems and represents a large source of uncertainty in estimating net ecosystem productivity (NEP) using regional soil respiration (RS) models. RH from leaf litter (RHL) may contribute greatly to annual RH estimates, but its contribution may be misrepresented due to the logistical ...

Equilibrium responses of global net primary production and carbon storage to doubled atmospheric carbon dioxide: sensitivity to changes in vegetation nitrogen concentration [PDF]

, 1997
We ran the terrestrial ecosystem model (TEM) for the globe at 0.5° resolution for atmospheric CO2 concentrations of 340 and 680 parts per million by volume (ppmv) to evaluate global and regional responses of net primary production (NPP) and carbon ...

Carbonate sedimentology: An evolved discipline

The Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Diverse morphologies found in living microbial mats and associated microbialites—A field report from the alkaline and hypersaline Nuoertu Lake, Badain Jaran Desert, N‐China

The Depositional Record, Volume 12, Issue 1, February 2026.
Diverse living microbial communities showing stacked mats and finger‐like branching examples that grow with the support of reed grass (phytomicrobialites) as well as aragonitic stromatolitic tufa have been rediscovered in the alkaline and hypersaline Lake Nuoertu in the Badain Jaran Desert N. China.

Climatic, edaphic, and biotic controls over storage and turnover of carbon in soils [PDF]

, 1994
Soil carbon, a major component of the global carbon inventory, has significant potential for change with changing climate and human land use. We applied the Century ecosystem model to a series of forest and grassland sites distributed globally to examine
