摘要
比较了四川、广东和海南3地的中菊头蝠(Rhinolophus affinis)种群的外部和头骨形态差异。在测量23个外部可量性状以及22个头骨可量性状的基础上,运用统计分析软件SPSS12.0对其中12个外部可量性状以及22个头骨可量性状进行数理统计。主成分分析的结果表明四川、广东和海南3地的中菊头蝠在外部形态和头骨形态上均有明显差异,用判别分析对主成分分析结果的正确性进行验证,证明了中国的中菊头蝠划为喜马拉雅、华南、海南3个亚种是合理的。
The isolation of Rhinolophus affinis from Guangdong and Hainan near the Qiongzhou Strait, and the differences in climate and landscape between the South of China and Sichuan Province, prompted our study of morphological divergence. We obtained data on 23 external characteristics and 22 skull characteristics, and the data of 12 external characteristics and 22 skull characteristics was analyzed with SPSS12.0. Principal components and discriminant analyses revealed there were distinct differences both in the external morphological measurements and in the skull measurements among Rhinolophus affinis in Sichuan, Guangdong and Hainan Province. These data suggest that there are three subspecies of Rhinolophus affinis, i.e, R. a. himalayanus Anderson, 1905, R. a. macrurus Anderson, 1905 and R. a. hainanus J Alien, 1906.
