摘要：

目的 探讨永州两种蝙蝠即斑蝠(SO)和普通伏翼蝠(PA)听觉器官的结构特征以及两者之间的异同。方法 对两种蝙蝠(SO: 5只；PA: 12只)的听觉器官进行显微解剖和相关参数的测量及统计学分析。结果 分离得到两种蝙蝠完整的鼓膜(SO: 9件；PA: 19件)、锤骨(SO: 10件；PA: 18件)、砧骨(SO: 10件；PA: 18件)、镫骨(SO: 6件；PA: 14件)、耳蜗(SO: 10只；PA: 24只)等构件；测得锤骨柄长、砧骨长突长、鼓膜面积、镫骨底面积、耳蜗蜗高与底宽等特征参数，这些参数在两种蝙蝠之间差异显著；两者中耳声压放大倍数分别是27.37（SO）和40.99（PA）倍，差异显著。 结论 两种蝙蝠虽然同属一科，却形成具有明显差异的听觉器官结构，而差异的存在应该是两者适应各自生活环境和匹配自身声行为的结果。

Abstract:

Objective To understand and compare the auditory organs ofScotomanes ornatus(SO) andPipistrellus abramus(PA) in Yongzhou of Hu’nan province.Methods The auditory organ components of 5 SO and 12 PA obtained through micro-dissection manipulation were measured and analyzed statistically. Results Complete tympanic membrane(SO: 9; PA: 19), malleus(SO: 10; PA: 18), incus(SO: 10; PA: 18), stapes(SO: 6; PA: 14) and cochlea(SO: 10; PA: 24) were isolated successfully. Characteristic parameters such as length of malleus’ helve, length of incus’ crus longum, height and bottom width of cochlea, area of tympanic membrane and stapes’ foot plate were measured, and significant difference existed in these characteristic parameters between two species. Amplification times of sound pressure in middle ear of the two species were 27.37 (SO) and 40.99 (PA), respectively, also showed significant difference. Conclusion Two species of bats shaped obviously different but matching their own living environment and acoustic behaviors auditory organs structure, although they are both belong to the same branch of vespertilionidae.
