TL;DR: It is reported that P limitation is more widespread and much stronger than previously estimated and often occurs in other regions, suggesting that previous studies have underestimated the importance of altered P supply on aboveground plant production in natural terrestrial ecosystems.

TL;DR: Overall, soil available P, indexed by Hedley labile inorganic P fraction, significantly decreased with increasing mean annual temperature (MAT) and precipitation (MAP), suggesting that temperature and precipitation have contrasting effects on soil P availability and can interact with soil particle size to control soil Pavailability.

TL;DR: In this article, the authors measured nitrogen and oxygen isotopic composition of NO 3 − in 113 precipitation samples collected from Guangzhou City in southern China over a two-year period (2008 and 2009).

TL;DR: In this paper, the authors studied litterfall in two subtropical monsoon vegetation gradients in the Dinghushan Biosphere Reserve, Guangdong Province, China.

TL;DR: The results indicate that the altitudinal pattern of plant and soil nutrient status differs among ecosystem components and that the relative importance of P vs. N limitation for ecosystem functions and processes shifts along altitudinal gradients.
