Abstract

Soils in south-western Australia have an extremely low phosphorus (P) concentration and various adaptation strategies evolved in native Proteaceae there. Myrtaceae, Fabaceae and Proteaceae growing in severely P-impoverished habitats exhibited multiple P-acquisition strategies. A variety of P-acquisition strategies were found in one genus of Proteaceae, Adenanthos. All Proteaceae in my study used P highly efficiently with a high photosynthetic P-use efficiency (PPUE), while not all Fabaceae and Myrtaceae had a high PPUE. Growing in the same severely P-impoverished soils, no covergent leaf P-allocation patterns were found among co-occurring species from Proteaceae, Myrtaceae and Fabaceae.
