A tipping point for tipping points

Oikos, EarlyView.
Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

More than proteins for empty stomachs: Wild meat in the BaTonga food system

People and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.

Direct extraction of functional whitened lignocellulose from wood via isocyanate modification in water–ethanol mixture

Polymer International, EarlyView.
Direct extraction of lignocellulose from wood derivatives was achieved by introducing a bulky isocyanate substituent to lignin in a water–ethanol mixture. This process exploits the tunable solvent affinity of lignin to achieve its whitening, enabling the isolation of lignocellulose.
