Escalation (macroevolutionary increase) or divergence (disparity between relatives) in trait values are two frequent outcomes of the plant-herbivore arms race. We studied the defences and caterpillars associated with 21 sympatric New Guinean figs. Herbivore generalists were concentrated on hosts with low protease and oxidative activity.

- - Researchers discovered complex polybrominated p-terphenyl ethers from a mushroom (Boletopsis sp.) traditionally used for medicine by the Kiovi people of Papua New Guinea.
- - Boletopsins 13 and 14 are the first known polybrominated metabolites created by a terrestrial fungus.
- - The synthesis method used involves 2,4,4,6-tetrabromo-2,5-cyclohexadienone to selectively polybrominate the aromatic system in a controlled, step-by-step process.
Exhaustive hydro-distillation of the leaves of Piper aduncum and fruits of Piper gibbilimbum (Piperaceae) afforded colorless and pale orange colored oils in 0.35 and 0.30 % yields, respectively.
