Lianas shift towards larger sizes and more acquisitive trait values in an Asian tropical rainforest
Biotropica, Volume 56, Issue 2, March 2024.Liana communities showed a shift in trait values indicating that they changed towards more large, acquisitive lianas with rapid water use. There are more larger stems through time due to the relatively low mortality of the larger individuals, which is associated with relatively low levels of disturbance.

GCB Bioenergy, Volume 16, Issue 1, January 2024.The use of biochar increased greenhouse gas (GHG) emissions but countered the harm caused by GHG emissions by considerable soil carbon sequestration resulting in a negative carbon footprint. Furthermore, the use of biochar lowered the proportion of CH4 and N2O, demonstrating that biochar usage has a considerable positive effect on GHG emissions ...

The Effect of N2O Emission Mitigation by Growing Soybeans Instead of Other Crops [PDF]
, 2016 农业是重要的温室气体排放源之一，而在农业生产过程中施用氮肥是引起农业温室气体排放的主要原因。因此，如何合理有效的施用氮肥对减少农业温室气体排放、减缓全球气候变化至关重要。鉴于此，对通过合理施用氮肥从而减少温室气体排放的减排措施进行成本效益分析，将有助于我们找到具有经济效益的农业温室气体减排方法。目前，相关减排措施研究主要集中在农田测土配方施肥、改良施肥（缓释肥和长效肥）上。得益于与豆类作物共生的根瘤菌具有的固氮作用，豆类作物相比其他农作物施用更少的氮肥，从而排放更少的氧化亚氮（N2O）。因此 ...
