A Well-Balanced Ecosystem Uses Water Most Efficiently

by Elizabeth Thompson 13 May 202128 September 2021

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.

Deep-Ocean Oxygen May Increase with Climate Change

by Kate Wheeling 17 September 2020

A millennial-scale ocean simulation indicates that oxygen gains in the deep ocean may offset oxygen losses in the upper water layer under a protracted climate change scenario.
