英文摘要: The clicks of Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) from 7 individuals in the tank of Baiji aquarium, 2 individuals in a netted pen at Shishou Tian-ezhou Reserve and 4 free-ranging individuals at Tianxingzhou were recorded using a broadband digital recording system with four element hydrophones. The peak-to-peak apparent source level (ASL_(pp)) of clicks from individuals at the Baiji aquarium was 167 dB re 1 mu Pa with mean center frequency of 133 kHz, -3dB bandwidth of 18 kHz and -10 dB duration of 58 mu s. The ASL_(pp) of clicks from individuals at the Shishou Tian-e-zhou Reserve was 180 dB re 1 mu Pa with mean center frequency of 128 kHz, -3dB bandwidth of 20 kHz and -10 dB duration of 39 mu s. The ASL_(pp) of clicks from individuals at Tianxingzhou was 176 dB re 1 mu Pa with mean center frequency of 129 kHz, -3dB bandwidth of 15 kHz and -10 dB duration of 48 mu s. Differences between the source parameters of clicks among the three groups of finless porpoises suggest these animals adapt to their echolocation signals depending on their surroundings.
