Fig. 4

Effects of soil texture on oviposition. Numbers of egg rafts (y axis) laid in water cups are shown for different treatments (x axis) from experiments with A only soil–water and soil substrate (no organic matter added) and B soil–water, soil substrate, and 0.1 mg added organic matter (fish food). Individual plot points denote the number of egg rafts oviposited in each treatment cup in a single experimental replicate. The boxes show the interquartile range of egg raft counts, the median is shown as a solid black line, and outliers as black circles
