摘    要:在地处四川省洪雅县的瓦屋山国家森林公园录取了锄足蟾科 6种的繁殖期求偶鸣叫声。它们分隶 4属 ,即角蟾属 (Megophrys)、齿蟾属 (Oreolalax)、齿突蟾属 (Scutiger)和掌突蟾属 (Leptolalax)。在IBMPC上用“SIGNAL”软件 (EngineeringDesign ,USA)对获取的鸣声资料进行分析 ,分析的频率范围设置为 0~ 10kHz。声学分析结果表明 :峨山掌突蟾 (L oshanensi) ,小角蟾 (M minorr) ,角蟾 1种 (M sp) ,金顶齿突蟾S (S )chintingensis],峨眉齿蟾 (O omeimontis)和无蹼齿蟾 (O schmidti)的主能峰频率平均值分别是45 2 1 9、 34 5 6 4、 2 2 93 8、 10 76 5、 10 71 0和 1849 4Hz ,每声持续时间的平均值分别是 46 2、 90 8、 99 6、72 2、 78 8和 110 3ms ,声距的平均值分别是 140 4、 2 5 3 0、 6 81 4、 15 17 7、 46 1 3和 6 19 5ms。单因子方差分析结果表明主能峰频率、每声持续时间和各声距在 6个种间差异极显著 (P <0 0 1)。LSD法多重比较的结果指出金顶齿突蟾和峨眉齿蟾间的主能峰频率无显著差异 (P =0 917>0 0 5 ) ;在每声持续时间上 ,只有峨山掌突蟾与小角蟾、角蟾 1种、峨眉齿蟾、无蹼齿蟾间差异极显著 (P <0 0 1) ;在声距上 ,峨山掌突蟾与小角蟾间无显著差异 ,角蟾 1种与无蹼齿蟾之间、峨

Abstract:The mating calls of six forms belonging to four genera Megophrys,Oreloalax,Scutiger and Leptolalax were recorded in Wawu Mountain National Forest Park,Sichuan Province of China,using cassette tape recorder (Aiwa) and Sony tape with an external microphone.All recordings were analyzed with an IBM PC based "SIGNAL" software analysis system (Engineering Design,USA).The range of analyzed frequency was set as 0-10 kHz.Acoustic analysis shows that the dominant frequency of L.oshanensis,M.minor,M.sp.,S.(S.)chintingensis,O.omeimontis,and O.schmidti is 4521.9,3456.4,2293.8,1076.5,1071.0 and 1849.4 Hz on average respectively;the note duration is 46.2,90.8,99.6,72.2,78.8 and 110.3 millisecond on average respectively;the note interval is 140.4,253.0,681.4,1517.7,461.3 and 619.5 millisecond on average respectively.One-Way ANOVA analysis indicates that there are significant differences among the analyzed six forms on the dominant frequency,the note duration,and the note interval (P<0.01).Multiple comparisons using Least-Significant Difference (LSD) show that the difference of the dominant frequency between S.(S.) chintingensis and O.omeimontis is not significant (P=0.917>0.05);on the note duration,only L.oshanensis is significantly different from M.minor,M.sp.,O.omeimontis and O.schmidti (P<0.01);on the note interval,L.oshanensis is not significantly different from M.minor,the same with M.sp.versus O.schmidti and O.omeimontis versus O.schmidti (P>0.05).Correlation analysis indicates that there are no significant correlation among the three acoustic characters of dominant frequency,note duration and note interval,and two environmental factors of the elevation and air temperature (P>0.05) except that the note interval is significantly linear correlated with the elevation (r=0.943,P=0.005<0.01).In the light of above,it is suggested that acoustic characteristics of calls are useful in distinguishing forms;the change of the note interval with the elevation may be a kind of strategy of reproduction.
