TLDR
A 35-year controlled burning experiment in Minnesota oak savanna showed that fire frequency had a great impact on ecosystem carbon (C) stores, with most carbon stored in woody biomass.Abstract:
A 35-year controlled burning experiment in Minnesota oak savanna showed that fire frequency had a great impact on ecosystem carbon (C) stores. Specifically, compared to the historical fire regime, fire suppression led to an average of 1.8 Mg·ha−1·yr−1 of C storage, with most carbon stored in woody biomass. Forest floor carbon stores were also significantly impacted by fire frequency, but there were no detectable effects of fire suppression on carbon in soil and fine roots combined, or in woody debris. Total ecosystem C stores averaged ∼110 Mg/ha in stands experiencing presettlement fire frequencies, but ∼220 Mg/ha in stands experiencing fire suppression. If comparable rates of C storage were to occur in other ecosystems in response to the current extent of fire suppression in the United States, fire suppression in the USA might account for 8–20% of missing global carbon.read more

Impacts of fire suppression on above‐ground carbon stock and soil properties in Borana rangelands, southern Ethiopia
TL;DR: In this article , the long-term impacts of fire suppression on aboveground carbon stocks of woody and herbaceous biomass, soil organic carbon stocks, and total nitrogen stocks at burned versus adjacent unburned areas in the Borana rangelands of southern Ethiopia were investigated.
Mountain Pine Beetle Disturbance and Climate Impacts on Subalpine Forest Carbon Cycling
TL;DR: In this article, the impacts of mountain pine beetle (MPB) induced tree mortality and changes in spring snow depth on forest carbon balance and soil biogeochemical pools were investigated.

Ion Transport Membranes (ITMs) for Oxygen Separation
TL;DR: In this paper, the use of ion transport membranes (ITMs) for O2 separation from air was discussed, and it was shown that the permeation of oxygen through the ion transport membrane depends on the membrane type, thickness, operating temperature and the difference in oxygen partial pressure across the membrane.

Prescribed burning effects on savanna fire spread, intensity, and predictability
TL;DR: Predicting fire spread and intensity has been a poor endeavour thus far and it is shown that more data of the variables already monitored would not result in higher predictive accuracy, and is suggested to investigate further the use of climatic refugia against wildfires.
Mountains, fire, fire suppression, and the carbon cycle in the western United States
TL;DR: In this paper, the authors estimate that only 5 to 15 percent of the old-growth forests in the western United States are covered by forests, which are for the most part recovering from historical harvesting and have been experiencing active fire suppression over approximately the past 100 years.

TL;DR: Slowing deforestation, combined with an increase in forestation and other management measures to improve forest ecosystem productivity, could conserve or sequester significant quantities of carbon.

Terrestrial ecosystems and the carbon cycle
TL;DR: The terrestrial biosphere plays an important role in the global carbon cycle as mentioned in this paper, which is the fluxes of carbon among four main reservoirs: fossil carbon, the atmosphere, the oceans, and the terrestrial Biosphere.

Biogeochemistry, An Analysis of Global Change
TL;DR: The first edition of Schlesinger's Biogeochemistry in 1991 was an early entry in the field of Earth system science/global change, and has since gained sufficient popularity and demand to merit a second, extensively revised edition.

The U.S. Carbon Budget: Contributions from Land-Use Change
TL;DR: The rates at which lands in the United States were cleared for agriculture, abandoned, harvested for wood, and burned were reconstructed from historical data for the period 1700-1990 and used in a terrestrial carbon model to calculate annual changes in the amount of carbon stored in terrestrial ecosystems, including wood products.
