About the Cover
Cover: Sensory ecology in a predator−prey system. Walking arthropods unwillingly reveal their whereabouts to potential predators by faint rustling sounds. Predators can use the amplitude of arthropod walking sounds to learn about prey size and profitability. However, as Goerlitz, Greif and Siemers show (pp. 2799−2806), the walking substrate (e.g. bare soil, meadow, forest floor) strongly affects these amplitude cues. For an efficient foraging decision based on the prey rustling it hears, the hunting greater mouse-eared bat (Myotis myotis) shown here will thus need to recognize and account for the substrate on which the carabid beetle is walking. Artwork assembled by Leonie Baier using a photo by Dietmar Nill.
