a HRHN, higher rain, high nutrients; MQ, Macquarie University campus (also higher rain); HRLN, higher rain, low nutrients; LRHN, lower rain, high nutrients; LRLN, lower rain, low nutrients. High rainfall sites experience c. 1220mm annual rainfall, low rainfall sites c. 800mm (climate data from the Australian Bureau of Meteorology; further site details given by Niinemets et al., 2009b).
