Fig. 2 in Bagnalliella mojave (Thysanoptera: Phlaeothripidae) thrips inhabit small and isolated Yucca brevifolia (Agavaceae) host plants

Fig. 2. Number of leaf clusters on Yucca brevifolia vs. mean distance from plant to nearest Yucca schidigera or Y. brevifolia in 4 quarters. Yucca brevifolia plants are inhabited (closed circles) or uninhabited (open circles) by Bagnalliella mojave. Axes are log scales. Solid line is Y regressed on X. Dashed lines are the same regression with thrips presence or absence added as an indicator variable.
