Elevated CO2 is expected to lower plant nutrient concentrations via carbohydrate dilution and increased nutrient use efficiency. Elevated CO2 consistently lowers plant foliar nitrogen, but there is no consensus on CO2 effects across the range of plant nutrients. We...

Six terrestrial ecosystems in the USA were exposed to elevated atmospheric CO2 in single or multifactorial experiments for more than a decade to assess potential impacts. We retrospectively assessed soil bacterial community responses in all six-field experiments and...

Plant growth often responds rapidly to experimentally simulated climate change1, 2. Feedbacks can modulate the initial responses3, but these feedbacks are difficult to detect when they operate on long timescales4. We transplanted intact plant–soil mesocosms down an...

Evidence is mounting that extinctions are altering key processes important to the productivity and sustainability of Earth’s ecosystems1, 2, 3, 4. Further species loss will accelerate change in ecosystem processes5, 6, 7, 8, but it is unclear how these effects compare...

Global environmental changes are expected to alter ecosystem carbon and nitrogen cycling, but the interactive effects of multiple simultaneous environmental changes are poorly understood. Effects of these changes on the production of nitrous oxide (N2O), an important...
