Soil Respiration in Tibetan Alpine Grasslands: Belowground Biomass and Soil Moisture, but Not Soil Temperature, Best Explain the Large-Scale Patterns
The Tibetan Plateau is an essential area to study the potential feedback effects of soils to climate change due to the rapid rise in its air temperature in the past several decades and the large amounts of soil organic carbon (SOC) stocks, particularly in the permafrost. Yet it is one of the most under-investigated regions in soil respiration (Rs) studies. Here, Rs rates were measured at 42 sit...
متن کاملSoil Temperature, Moisture, and Carbon and Nitrogen Mineralization at a Taiga-Tundra Ecotone, Noatak National Preserve, Northwestern Alaska
Northwestern Alaska has been warming (0.3°C/yr) since the early 1990s. Ecotonal (treeline) Arctic ecosystems are expected to exhibit the effects of climate change earliest. High-latitude terrestrial ecosystems contain from 30 to 45 percent of the global organic-C pool. Soil warming may enhance release of CO2 and CH4, soil N mineralization, and the production and export of dissolved organic C an...
متن کاملSensitivity of Soil Respiration to Variability in Soil Moisture and Temperature in a Humid Tropical Forest
Precipitation and temperature are important drivers of soil respiration. The role of moisture and temperature are generally explored at seasonal or inter-annual timescales; however, significant variability also occurs on hourly to daily time-scales. We used small (1.54 m(2)), throughfall exclusion shelters to evaluate the role soil moisture and temperature as temporal controls on soil CO2 efflu...

متن کاملSimulated Seasonal Spatio-temporal Patterns of Soil Moisture, Temperature, and Net Radiation in a Deciduous Forest
The temperature and moisture regimes in a forest are key components in the forest ecosystem dynamics. Observations and studies indicate that the internal temperature distribution and moisture content of the tree influence not only growth and development, but onset and cessation of cambial activity[1], resistance to insect predation[2], and even affect the population dynamics of the insects[3]. ...
