四个猕猴地理种群惊叫行为的比较

COMPARISON AMONG RHESUS MONKEY POPULATIONS IN A SCREAM

对华南地区４个猕猴种群惊叫行为的比较表明：叫声发生时，发声猴的行为在地理种群间的差异不明显。在叫声的频谱结构方面，个体间的差异不明显；湖南索溪峪、广西龙虎山、海南南湾种群间差异不明显，但深圳内伶仃岛种群与上述３个地理群间有明显差异。判别分析表明，基频频率（Ｆ１）是区分猕猴上述各地理种群间异同的重要参数。这些结果为研究猕猴的分类及演化提供了基础资料。对上述的猕猴地理种群，惊叫声传输性较好和“符号”较专一而有效与群体大、生境降雨量小的相关，本质上是惊叫声对内陆、热带地区。

Among four rhesus monkey populations, comparing in a scream indicates that there is no significant difference in the subsequent behaviors of screamer. In spectrum characters of the scream, there are no significant differences,among individuals and among the free geographic populations of Hunan′s Suoxiyu, Guangxi′s Longhushan and Hainan′s Nanwan. But, between the above three populations and Shenzhen′s Neilingding population, the difference in the scream′s spectrum characters is significant.The result from discriminant analysis, reveals that the fundamental frequency (F 1) of screams is important to interpopulation discriminating. For the different populations, the tendency to increased audible range and signal specialization in rhesus′s scream, is related to the lighter rainfall of habitat and larger group size. In fact, it is essential, that the tendencies relating to rainfall and group size in rhesus′s scream are the adaptations to mainland, island and tropic area.
