Calling song of the cricket Gryllus assimilis is unusual among Gryllus spp. in the high sound-pulse rate, ca. 80 Hz, within its chirps. We asked whether, as in other cricket species, females were able to analyze such a high pulse rate. In phonotaxis experiments, females failed to respond to stimuli with ...

The co-occurrence of functionally similar species is very common in nature, and is often put forward as a basis for ecosystem resilience to disturbance. At the same time, competition between similar species is also considered a strong driver of community composition. However, environmental stochasticity can alter this prediction, either because ...
