Title Juergens et al_Trap data
Downloaded 42 times
Description Microsoft Excel worksheet with trap data of insects found on different artificial traps. Experiments with white, green, and red artificial sticky traps to test the effect of: flower stalk length (2 cm vs. 8 cm) on pollinator attraction; trap positioning (on the ground, D. spatulata type, vs. upright, D. arcturi type) on prey (excluding pollinators) and pollinator capture; presence of flowers on prey and pollinator capture; and trap colour on prey and pollinator capture.

Description Generalized linear model showing the effect of stalk length (2 cm vs. 8 cm) on the average number of Drosera pollinators captured on artificial sticky flowers (Fig. 2A) at two sites and two days (χ21,60 = 4.86; p < 0.05)

Title Figure 5
Downloaded 1 time
Description Generalized linear model showing the effect of different colours (green vs. red) of model leaves (Figs 2D, E, F) on number of captured (A) prey (excluding Drosera pollinators) and (B) potential Drosera pollinators (All prey: χ21,90 = 11.72; p<0.001; Pollinators: χ21,90 = 9.15; p<0.01). The presence or absence of non-sticky flowers (2 cm and 8 cm) had no effect on capture of sticky model leaves (Pollinators: χ21,90 = 0.617; p = 0.734 All prey: χ21,90 = 1.35; p = 0.51).

Title Figure 6
Downloaded 3 times
Description Generalized linear models showing the effect of trap colour and trap positioning on pollinator capture on model leaves (A) and model flowers (B) respectively (see Figs 2B, C). (A) Effect of trap colour (χ21,60 = 10.19; p < 0.01) on pollinator capture of model leaves. (B) Trap positioning (upright vs. on the ground) showed no significant effect on pollinator capture in model traps (χ21,60 = 0.245; p < 0.62). (B) Effect of trap positioning (χ21,60 = 4.62; p < 0.05) but not trap colour (χ21,60 = 1.85; p < 0.174) on pollinator capture of model flowers.
