Table 2.
Pairwise comparisons between ‘treatment’ levels (bagged plants, ant-excluded plants, and plants exposed to pollinators and ants) and ‘species’ (Dyckia floribunda and D. longipetala) for both response variables: ‘fruit set’ and ‘seeds per plant’. Differences between the means (Estimate), standard deviations (SEs) of these differences, and p-values adjusted using the Tukey method are presented.
