Abstract: Acoustic plasticity is important bats to adapt to different situations and habitats,as well as for foraging and social communication. To examine this ability in Himalayan leaf-nosed bats (Hipposideros armiger),echolocation calls from a total of 11 individuals were recorded both inside and outside of the laboratory. Specifically they were placed in artificial habitats with four levels of complexity,and also in four behavioral situations (i. e. held in hand,kept in bag,resting and free flying in door). The four artificial habitats were indoors with no-trees,one-trees or five-trees,and free-flying outdoors. Outdoors we recorded the calls while they were released in their natural habitat. The results showed that the Himalayan leaf-nosed bat emits CF-FM echolocation calls,in which normally continuous 2 - 4 pulses form a pulse group. When comparing the echolocation calls among four different behavioral situations,the dominant frequency was highest while resting lower when kept in bag,lower still when held in hand,and tlowest when free-flying indoors,while the frequency range of TFM was shortest when held in hand,followed by kept in bag and free flying indoors,and longest while resting. The pulse duration and inter-pulse intervals both increased during resting,free flying in door,kept in bag,and held in hand, respectively. When comparing the echolocation calls among free-flying bats in four habitats of different complexities,the dominant frequency being lowest outdoors, followed by indoors with no-trees,one-tree and five-trees,respectively,while the pulse duration and inter-pulse interval both decreased in the same order. The frequency range of TFM when the bats were released outoors was shorter than those when bats were flying indoors. These results indicate that the echolocation calls of Himalayan leaf-nosed bat have significant plasticity under different situations and habitat complexities,and are part of their environmental adaptation.

摘要: 蝙蝠回声定位声波的可塑性对其适应不同状态、生境以及捕食和社会交流具有重要的作用。为进一步研究大蹄蝠的回声定位声波在不同状态和生境下的可塑性,通过室内行为实验,对大蹄蝠在4 种不同状态(室内飞行、静息、布袋内和手持)和4 种不同生境复杂度(室外、室内0 棵树、室内1 棵树、室内5 棵树)条件下飞行的回声定位声波特征进行研究。结果表明:大蹄蝠的回声定位声波为CF - FM 型,通常连续发出2 - 4 个脉冲组成一个脉冲组。对比大蹄蝠在4 种不同状态下的回声定位叫声发现,主频按静息、布袋内、手持、飞行的顺序依次降低,后端FM 频宽则按手持、布袋内、飞行和静息的顺序依次变短;而脉冲间隔和脉冲时程则均按静
息、飞行、布袋内、手持的顺序依次增加。对比大蹄蝠在4 种不同生境复杂度中飞行的回声定位叫声发现,主频按室外、室内0 棵树、室内1 棵树、室内5 棵树依次提高,而脉冲时程及脉冲间隔则依次缩短;室外放飞条件下的后端FM 频宽比室内飞行的短。研究结果说明,大蹄蝠在不同状态、不同生境复杂度条件下的回声定位叫声具有明显的可塑性和生境适应性。
