Cold Pool Responses to Changes in Soil Moisture

Changes in the Size of the Active Microbial Pool Explain Short-Term Soil Respiratory Responses to Temperature and Moisture

Heterotrophic respiration contributes a substantial fraction of the carbon flux from soil to atmosphere, and responds strongly to environmental conditions. However, the mechanisms through which short-term changes in environmental conditions affect microbial respiration still remain unclear. Microorganisms cope with adverse environmental conditions by transitioning into and out of dormancy, a st...

Historical climate controls soil respiration responses to current soil moisture.

Ecosystem carbon losses from soil microbial respiration are a key component of global carbon cycling, resulting in the transfer of 40-70 Pg carbon from soil to the atmosphere each year. Because these microbial processes can feed back to climate change, understanding respiration responses to environmental factors is necessary for improved projections. We focus on respiration responses to soil mo...

Soil fungal community responses to global changes

The seasonal dynamics of soil fungal and bacterial communities are important for understanding the future ecosystem responses to global change due to their role in nutrient cycling and organic matter decomposition. After fourth year of increased temperature, extended drought and elevated CO2, soil samples were collected during one year to gain insight into how these treatments affected seasonal...

Study of Changes in Soil Moisture and Salinity Under PlasticMulch and Drip Irrigation in Pistachio Trees

In this study, changes in soil moisture and salinity contents in drip irrigation combined with white and black plastic mulches compared to no mulch (control) was evaluated. The experiment was carried out in two commercial pistachio orchards (Ohadi cultivar) with irrigation frequencies of 8 to 12 days with a total water consumption 4100 and 6170 m3ha−1. The study was conducted in a complete rand...

Changes in temperature - moisture covariance could increase soil carbon loss
