Payoff of the Grain for Green policy

Shixiong Cao, Chengqi Xia, Junli Xian, Hao Guo & Heran Zheng
1. To protect the global ecological environment and prevent threats to human safety and property, nations around the world have invested heavily in ecological restoration programmes. However, we don’t know whether these investments have been repaid by the resultant benefits. 2. To answer this question, we developed an improved method of quantifying costs and benefits that accounts for more of the costs associated with ecological restoration, thereby letting us calculate the net benefit. 3. To...

Grassland ecosystems account for more than 10% of the global CH4 sink in soils. A 4-year field experiment found that addition of P alone did not affect CH4 uptake and experimental addition of N alone significantly suppressed CH4 uptake, while concurrent N and P additions suppressed CH4 uptake to a lesser degree. A meta-analysis including 382 data points in global grasslands corroborated these findings. Global extrapolation with an empirical modeling approach estimated that contemporary N...

Data from: Survival strategy of the endangered tree Acer catalpifolium Rehd., based on 13C fractionation

Wenchen Song & Yanhong Liu
We conducted a field investigation and evaluation of 13C natural abundance to determine the growth habit and propagation strategy of Acer catalpifolium Rehd., a tree species native to China that is highly endangered. The results showed that A. catalpifolium is a K-selected strategist and pioneer species. Its narrow ecological range limits its geographical distribution, and poor fecundity limits its population size. The analysis of 13C natural abundance showed that A. catalpifolium does not use organic...
