Soil Carbon Dynamics in Lawns Converted From Appalachian Mixed Oak Stands
… results in dramatic changes to vegetation and soils, which may affect soil carbon storage. To better understand the effects of landscape conversion and management on soil carbon, we conducted a study on residential properties in the Valley and Ridge physiographic province of southwest Virginia …

Soil carbon dynamics in the upper Mersey estuarine floodplain, northwest England : implications for soil carbon sequestration
There have been several studies on soil carbon dynamics in estuarine floodplains. However, little attempt has been made to examine the effects of heavy metal contamination on these processes. This represents a knowledge gap that needs to be filled to understand better soil carbon decomposition in …

The effects of scale and context-dependency on the outcome of experiments investigating soil carbon dynamics
Soil carbon dynamics and plant-soil interactions are an integral part of ecosystem function and understanding the effects of perturbations on these processes is vital if we are to predict the future of ecosystems under global environmental change. However, it is often challenging to study complex …

The Influence of Urban Soil Rehabilitation on Soil Carbon Dynamics, Greenhouse Gas Emission, and Stormwater Mitigation
… has resulted in rapidly increased urban land. Soils are the foundation that supports plant growth and human activities in urban areas. Furthermore, urban soils have potential to provide a carbon sink to mitigate greenhouse gas emission and climate change. However, typical urban land development …

Integrated process-based simulation of soil carbon dynamics in river basins under present, recent past and future environmental conditions
Soils contain a large amount of carbon (C) that is a critical regulator of the global C budget. Already small changes in the processes governing soil C cycling have the potential to release considerable amounts of CO2, a greenhouse gas (GHG), adding additional radiative forcing to the atmosphere …

Effect of Forage Stand Termination Method and Fertilization History on Greenhouse Gas Emissions, Nutrient Supply Rates, and Soil Carbon Dynamics
… gas (GHG) production, as well as affect carbon (C) and nutrient cycling in the soil. The objective of this thesis work was to examine the influence of grass forage stand termination method on GHG production, nutrient cycling, and dynamics of various soil C pools. Additionally, the …

Tree functional diversity affects litter decomposition and arthropod community composition in a tropical forest
… crucial role of tropical forests in the global carbon balance is determined by tree growth and the rapid turnover of organic material. Land-use change and forest recovery from disturbance alters species- and functional diversity, which in turn can modify decomposition processes and affect …

The influence of leaf litter and plants on soil respiration before, during and after a severe drought
… droughts may have a huge effect on ecosystem carbon storage but despite the importance of drought events, their effect on soil carbon dynamics are less well understood. The above-below ground linkages that affect soil dynamics in forested areas during drought and immediately after rewetting …

Linking The Functional Diversity Of Ectomycorrhizal Fungal Species To Soil Carbon And The Genetics Of A Foundational Tree Species
Carbon dioxide in the atmosphere continues to increase, leading to an enhanced interest in the potential for ecosystems to sequester carbon. Soil could have a high potential to store carbon in these forests, but there is still a great deal to learn about how carbon storage in soils is influenced by …

Environmental Impact of Pasture-Based Milk Production in Integrated Crop-Livestock Systems
… focusing on enteric methane (CH₄) emissions, carbon (C) dynamics, and nitrogen (N) losses. The first objective assessed enteric CH₄ emissions from pasture-based Jersey dairy cows using eddy covariance (EC), feed intake, and milk yield data across four grazing campaigns, with footprint (FP) …

Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting
With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. As …
