Causes and consequences of frequent flowering on edges in the mast-seeding genus Chionochloa (Poaceae)

Recent work has shown that resource accumulation is important in allowing mast-seeding plants to display occasional intense reproductive efforts. Anecdotal reports suggest that Chionochloa tussocks (bunchgrasses) on patch edges flower more frequently, and it has been proposed that this is due to greater resource availability. This study aimed to quantify any edge effect in flowering effort in Chionochloa populations at Mt Hutt in the Southern Alps of New Zealand, and to look for correlations with available soil nutrients.
