Forest litter crickets prefer higher substrate moisture for oviposition: Evidence from field and lab experiments.

Niche theory predicts that crickets should show a bell-shaped oviposition response to substrate moisture. However, lab experiments with mole crickets showed a linear oviposition response to substrate moisture.
