Figure 2.

Fruit sets for Dyckia floribunda (dots) and D. longipetala (triangles) comparing experimental treatments (bagged plants, ant-excluded plants, and plants exposed to pollinators and ants). Values of fruit set for each treatment are presented showing all plants measured (each dot or triangle). Results of adjusted models are presented showing data for six different populations (random factor; see Table 1 for details): A–C for D. floribunda and D–F for D. longipetala, indicated with different colors. Different letters indicate differences between treatments for each species (capital letters for D. floribunda and lowercase letters for D. longipetala).
