The influence of soil structure on heterotrophic respiration response to soil water content

2020
<p>Soil respiration causes one of the largest terrestrial carbon fluxes and its accurate prediction is still a matter of on-going research. Understanding the functional link between soil heterotrophic respiration and soil water content is relevant for the estimation of climate change impacts on soil CO<sub>2</

Elevated rates of heterotrophic respiration in shrub-conditioned arctic tundra soils

Pedobiologia, 2019
Abstract The response of arctic ecosystems to global change will be critical for future climate, due to their vast stores of carbon. Climate warming appears to be linked to the expansion of shrubs across tundra, but it is unclear how shrubs affect the activity of soil microbes.

Soil heterotrophic respiration: Measuring and modeling seasonal variation and silvicultural impacts

Forest Ecology and Management, 2018
Abstract To determine the effectiveness of forests in sequestering atmospheric carbon (C), we must know the amount of fixed carbon dioxide (CO2) that is subsequently lost due to heterotrophic microbial activity in the soil. Furthermore, the heterotrophic proportion of total soil respiration (Rs) must be quantified as it changes between different ...

Radiocarbon-Based Assessment of Heterotrophic Soil Respiration in Two Mediterranean Forests

Ecosystems, 2015
The amount of soil organic carbon (SOC) released into the atmosphere as carbon dioxide (CO2), which is referred to as heterotrophic respiration (Rh), is technically difficult to measure despite its necessity to the understanding of how to protect and increase soil carbon stocks.

Asymmetric responses of soil heterotrophic respiration to rising and decreasing temperatures

Soil Biology and Biochemistry, 2017
Abstract Periodic changes in temperature commonly occur diurnally and seasonally. However, the response of soil heterotrophic respiration to rising and decreasing temperatures during these periods remains poorly understood; thus the feedback between climate change and carbon (C) cycling requires further investigation.

Multivariate conditional stochastic simulation of soil heterotrophic respiration at plot scale

Geoderma, 2010
Abstract Soil heterotrophic respiration fluxes at plot scale exhibit substantial spatial and temporal variability. Within this study secondary information was used to spatially predict heterotrophic respiration. Chamber-based measurements of heterotrophic respiration fluxes were repeated for 15 measurement campaigns within a bare 13 × 14 m 2 soil ...

[Effects of Simulated Acid Rain on Soil Respiration and Heterotrophic Respiration in a Secondary Forest].

Huan jing ke xue= Huanjing kexue, 2018
In order to investigate the effects of simulated acid rain on soil respiration and heterotrophic respiration in a secondary forest, a field experiment was carried out. A split-plot experiment was arranged in field. There were 4 blocks; each block had two main plots which were trenched and un-trenched plots.
