Evaluating two soil carbon models within the global land surface model JSBACH using surface and spaceborne observations of atmospheric CO₂ [PDF]

, 2020
The trajectories of soil carbon (C) in the changing climate are of utmost importance, as soil carbon is a substantial carbon storage with a large potential to impact the atmospheric carbon dioxide (CO2) burden.

Partitioning autotrophic and heterotrophic respiration in an ombrotrophic bog

Frontiers in Earth Science, 2023
Northern peatlands are globally significant carbon stores, but the sink strength varies from year to year due to changes in environmental conditions. Ecosystem respiration (ER) is composed of both autotrophic respiration (AR) that consists of respiration by plant parts, and heterotrophic respiration (HR) that consists of respiration by microbial ...

Moso bamboo expansion decreased soil heterotrophic respiration but increased arbuscular mycorrhizal mycelial respiration in a subtropical broadleaved forest

Forest Ecosystems, 2023
Moso bamboo (Phyllostachys Pubescens) expansion into adjacent forests has been widely reported to affect plant diversity and its association with mycorrhizal fungi in subtropical China, which will likely have significant impacts on soil respiration ...

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Integrating functional diversity, food web processes, and biogeochemical carbon fluxes into a conceptual approach for modeling the upper ocean in a high-CO2 world [PDF]

, 2005
Marine food webs influence climate by channeling carbon below the permanent pycnocline, where it can be sequestered. Because most of the organic matter exported from the euphotic zone is remineralized within the "upper ocean" (i.e., the water column ...

The influence of soils on heterotrophic respiration exerts a strong control on net ecosystem productivity in seasonally dry Amazonian forests [PDF]

Biogeosciences, 2015
Net ecosystem productivity of carbon (NEP) in seasonally dry forests of the Amazon varies greatly between sites with similar precipitation patterns.

Investigating the sensitivity of soil heterotrophic respiration to recent snow cover changes in Alaska using a satellite-based permafrost carbon model [PDF]

Biogeosciences, 2020
The contribution of soil heterotrophic respiration to the boreal–Arctic carbon (CO2) cycle and its potential feedback to climate change remains poorly quantified.

Predicting plankton net community production in the Atlantic Ocean [PDF]

, 2009
We present, test and implement two contrasting models to predict euphotic zone net community production (NCP), which are based on 14C primary production (PO14CP) to NCP relationships over two latitudinal (ca.

Autotrophic and heterotrophic components of soil respiration caused by rhizosphere priming effects in a plantation

Plant, Soil and Environment, 2017
Root-exudate inputs can stimulate the decomposition of soil organic carbon by priming microbial activity, but its ecological significance is still not fully understood.
