Fig. 1 Daily mean river heights at three gauges on the Mary River, Northern Territory: (A) 98 km upstream; (B) 1 km downstream; (C) 47 km downstream of the Mary River Park bamboo study area. Gaps in the river depth line indicate missing data due to gauge malfunction. Note the concurrent similarities in relative gauge measurements along the Mary River. Data supplied by the Dept. of Natural Resources, Environment and the Arts, Northern Territory.

Table 1 Weighted model-averaged coefficients, and associated standard errors, for

correlates of proportional annual survival of clump basal area in the bamboo Bambusa arnhemica. Note that Year 2001-02 and its interaction with Position have been aliased (i.e. the intercept is for Year 2001-02, with recruitment, previous recruitment, position and density = 0)
