As wildfires blaze through the Arctic, scientists examine the role of landscape characteristics on wildfire ecosystem responses in northern aquatic ecosystems.
Benefits might accrue for both wildlife and climate resiliency if more floodplains along the lower Missouri River were allowed to flood.
Research indicates that wildfires could be bolstering soil emissions of air pollutants that contribute to smog and climate change.
Prodigious quantities of nitrogen from human waste flow into coastal waters, a study of nearly 135,000 watersheds reveals.
Statistical and numerical models show that denitrification efficiency is a key parameter controlling the production of N2O from rivers, providing a target for river restoration projects.
A new study challenges the assumption that cyanobacteria were the only major nitrogen fixers in the Proterozoic eon.
Food production is becoming less efficient at using nitrogen fertilizer, according to a review of global values. Excess nitrogen damages the environment and the climate.
Researchers compared the nitrogen removal potential by microbes in ditches that drained forested, urban, and agricultural lands and discovered that roadside ditches are important areas for removing nutrients.
Excess of a single nutrient, such as nitrogen, may boost plant productivity, but the imbalance leads to less efficient water use as plants scramble for the nutrients they lack.
