Declines in ecosystem productivity fueled by nitrogen-induced species loss

Humans have been affecting their environment since the ancestors of Homo sapiens first walked upright, but never has their impact been more detrimental than in the 21st century. Human-driven environmental disturbances, such as increasing levels of reactive nitrogen and carbon dioxide, have multiple effects, including changes in biodiversity, species composition, and ecosystem functioning. Pieces of this puzzle have been widely examined but this new study puts it all together by examining multipl...
