The influence of moth hearing on bat echolocation strategies

摘要: The ears of moths we tested in Canada and Cote d'Ivoire are most sensitive to sounds between 20 40 kHz, much less sound over 65 kHz. insectivorous bats commonly encountered these (and other) locations use high intensity, frequency modulated echolocation calls with components the 20–40 kHz range, making them detectable by tympanate up m away. In Africa such as species Nycteridae, Megadermatidae, some Hipposideridae, low intensity components, not at 2 m. hearing ability may significantly influence feeding efficiency bats, changes bat can drastically reduce range which detected, thus time available for evasive behaviour (Fig. 4). constitute a counter-maneuver against insects tuned calls.
