Nutrient Enrichment Increases Grassland Biomass Sensitivity to Interannual Precipitation Variation

Global Change Biology, Volume 32, Issue 8, August 2026.
We used data from 35 grasslands in the Nutrient Network (NutNet) to test if NPK addition alters how plant biomass responds to year‐to‐year variation in precipitation. We found that nutrient addition increased average biomass, rain‐use efficiency, and the sensitivity of biomass to interannual variation in precipitation, but did not change the strength ...

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...
