Microbial volatile fingerprints: potential use for soil/water diagnostics and correlation with traditional microbial parameters [PDF]

open access: yes, 2007
This project used an electronic nose (E-nose) system composed of an array of 14 nonspecific conducting polymer sensors for soil and water diagnostics, based on qualitative microbial volatile production patterns. It tested the feasibility of using soil

Soil respiration patterns and rates at three Taiwanese forest plantations: dependence on elevation, temperature, precipitation, and litterfall

open access: yesBotanical Studies, 2017
Background Soil respiration contributes to a large quantity of carbon emissions in the forest ecosystem. In this study, the soil respiration rates at three Taiwanese forest plantations (two lowland and one mid-elevation) were investigated.

Response of Bare Soil Respiration to Air and Soil Temperature Variations According to Different Models: A Case Study of an Urban Grassland

open access: yesLand, 2023
Soil respiration is an important component of the global carbon cycle and is highly responsive to disturbances in the environment. Human impacts on the terrestrial ecosystem lead to changes in the environmental conditions, and following this, changes in ...

Temporal variation and climate dependence of soil respiration and its components along a 3000 m altitudinal tropical forest gradient [PDF]

open access: yes, 2010
To simulate the effect of temperature on soil respiration rates, we translocated soil cores among four sites (3030, 1500, 1000, and 200 m asl) along an altitudinal tropical forest gradient in the Peruvian Andes, traversing a difference in mean annual ...

Bomb-14C analysis of ecosystem respiration reveals that peatland vegetation facilitates release of old carbon [PDF]

open access: yes, 2009
The largest terrestrial-to-atmosphere carbon flux is respired CO2. However, the partitioning of soil and plant sources, understanding of contributory mechanisms, and their response to climate change are uncertain.

Soil microbial respiration adapts to higher and longer warming experiments at the global scale

open access: yesEnvironmental Research Letters, 2023
Warming can affect soil microbial respiration by changing microbial biomass and community composition. The responses of soil microbial respiration to warming under experimental conditions are also related to background conditions and the experimental ...

Factors controlling spatio-temporal variation in carbon dioxide efflux from surface litter, roots, and soil organic matter at four rain forest sites in the eastern Amazon [PDF]

open access: yes, 2007
This study explored biotic and abiotic causes for spatio-temporal variation in soil respiration from surface litter, roots, and soil organic matter over one year at four rain forest sites with different vegetation structures and soil types in the eastern

Soil respiration of four forests along elevation gradient in northern subtropical China

open access: yesEcology and Evolution, 2019
Background and aims Soil respiration is the second‐largest terrestrial carbon (C) flux, and soil temperature and soil moisture are the main drivers of temporal variation in soil respiration and its components. Here, we quantified the contribution of soil

Influence of drainage status on soil and water chemistry, litter decomposition and soil respiration in central Amazonian forests on sandy soils [PDF]

open access: yes, 2011
Central Amazonian rainforest landscape supports a mosaic of tall terra firme rainforest and ecotone campinarana, riparian and campina forests, reflecting topography-induced variations in soil, nutrient and drainage conditions.

Spatial and temporal variations of soil microbial respiration under native and exotic tree species [PDF]

open access: yesInternational Research Journal of Science, Technology, Education, and Management, 2023
Different tree species can directly or indirectly affect soil conditions. They influence soil microbial diversity and abundance and hence soil respiration.
