Figure 1 Fig. 1. (A) New Zealand weta (Deinacrida rugosa, {approx}70 mm). [Photograph by B. Robertson] (B) The effect of weta ingestion on seed germination. Average percent germination of P. physaloides (±SE) seeds dispersed by New Zealand weta versus seeds manually extracted from pulp (control). Germination increased through time (repeated measures ANOVA, F3,23 = 148.3, P < 0.001) and was enhanced by weta ingestion (F1,9 = 8.3, P < 0.05). Both factors did not interact (F3,26 = 1.0, P > 0.10). Statistically similar results were obtained for F. excorticata. [View Larger Version of this Image (49K GIF file)]
