Warming climate reduces permafrost's ability to recover following wildfires in Alaskan lowland forest.
Given enough time, short-term variations in temperature, precipitation, and solar radiation influence the fluxes of water and carbon through ecosystems.
Drought conditions dictate whether atmospherically deposited sulfate stays locked in a peatland or is mobilized to stimulate the bacterial methylation of mercury.
Scientists examine nitrous oxide production in aquatic environments and the conditions that drive it.
Field observations show that with climate change, fiercer tropical storms may release more particulate nitrogen from temperate forests into aquatic ecosystems.
The largest body of fresh water on Earth governs the exchange of gases between water and the atmosphere that makes it a carbon sink for the entire region.
Fungi and bacteria deposit metal ions on steel objects left behind by miners. These metals form strange clam-like shells on the steel surfaces.
Field experiments examine the effect of rising temperatures and drying soils on carbon dynamics in the Arctic.
