Seasonal and spatial variability in plankton production and respiration in the Subtropical Gyres of the Atlantic Ocean [PDF]
, 2008 Euphotic zone plankton production (P) and respiration (R) were determined from the in vitro flux of dissolved oxygen during six latitudinal transects of the Atlantic Ocean, as part of the Atlantic Meridional Transect (AMT) programme.

Autotrophic component of soil respiration is repressed by drought more than the heterotrophic one in dry grasslands [PDF]
Biogeosciences, 2016 Summer droughts projected to increase in central Europe due to climate changes strongly influence the carbon cycle of ecosystems. Persistent respiration activities during drought periods are responsible for a significant carbon loss, which may turn the ...

Soil respiration in Chinese tea gardens: autotrophic and heterotrophic respiration
European Journal of Soil Science, 2018 Summary To obtain an improved understanding of the response of soil respiration ( R S ) to soil temperature and water content, we used a trenching treatment that could divide R S

Soil Carbon Release and Microbial Biomass Characteristics in Different Pinus massoniana Forests in Three Gorges Reservoir area [PDF]
长江科学院院报[Objective] As a hotspot region of soil respiration and carbon pool dynamics, the Three Gorges Reservoir area is most extensively covered by Pinus massoniana forests, whose soil organic carbon storage is the largest among all forest types.

Growing season CO2 fluxes from a drained peatland dominated by Molinia caerulea [PDF]
Mires and Peat, 2019 (1) Molinia caerulea occurs in peatland vegetation communities. However, under certain environmental and management conditions it may overwhelm the typical peatland vegetation, compromising ecosystem services including carbon dioxide (CO2) sequestration ...

Vegetation type determines heterotrophic respiration in subalpine Australian ecosystems [PDF]
Global Change Biology, 2009 AbstractSoils are the largest store of carbon in the biosphere and cool‐cold climate ecosystems are notable for their carbon‐rich soils. Characterizing effects of future climates on soil‐stored C is critical to elucidating feedbacks to changes in the atmospheric pool of CO2.

Heterotrophic Respiration and the Divergence of Productivity and Carbon Sequestration [PDF]
Geophysical Research Letters, 2021 AbstractNet primary productivity (NPP) and net ecosystem production (NEP) are often used interchangeably, as their difference, heterotrophic respiration (soil heterotrophic CO2 efflux, RSH = NPP−NEP), is assumed a near‐fixed fraction of NPP. Here, we show, using a range‐wide replicated experimental study in loblolly pine (Pinus taeda) plantations that ...
