The impact on nitrogen (N) and phosphorus (P) cycles of human activity is a growing
concern and has several causes and consequences (MacDonald et al., 2011; Peñuelas et …

In this review I am drawing attention to some constraints and biases in CO2 enrichment
experiments and the analysis of data in the literature. Conclusions drawn from experimental …

Direct quantification of terrestrial biosphere responses to global change is crucial for
projections of future climate change in Earth system models. Here, we synthesized …

Root turnover is a critical component of ecosystem nutrient dynamics and carbon
sequestration and is also an important sink for plant primary productivity. We tested global …

Roots usually suffer greater exposure to multiple abiotic stresses than shoots. Therefore, the
root system can be as affected, or even more affected, than the aerial parts of a plant by such …

Long‐term exposure of plants to elevated [CO2] leads to a number of growth and
physiological effects, many of which are interpreted in the context of ameliorating the …

Changes in the production and turnover of roots in forests and grasslands in response to
rising atmospheric CO2 concentrations, elevated temperatures, altered precipitation, or …

Fine-root production and turnover are important regulators of the biogeochemical cycles of
ecosystems and key components of their response to global change. We present a nearly …

Climate changes will influence soil organisms both directly (warming) and indirectly
(warming and elevated CO2) via changes in quantity and quality of plant‐mediated soil C …

Experimental evidence from a diverse set of forested ecosystems indicates that CO2
enrichment may lead to deeper rooting distributions. While the causes of greater root …
