'Fire came to the rainforest, and Krajcberg began to agonize over the ruin. 'There was such smoke that I never saw the natural sun,' he recalled in a recent interview with The New York Times. 'I denounced the burning, but I didn't have any impact. At that time, burning the…

The Restionaceae is one of the three major families defining fynbos, the characteristic vegetation type of the Cape Floristic Region. Periodic fires with a frequency of 5 to 40 years are a natural phenomenon in fynbos vegetation. Fire-stimulated seed germination has been…

Some postfire annuals with dormant seeds use heat or chemical cues from charred wood to synchronize their gemmination with the postfire environment. We report that wood smoke and polar extracts of wood smoke, but not the ash of burned wood, contain potent cue(s) that stimulate…
