鳴叫是長(zhǎng)臂猿一個(gè)非常顯著的特征。所有的成年長(zhǎng)臂猿都能發(fā)出響亮的鳴叫,。這種鳴叫具有種間的特異性,，有一定的固定模式，能傳播很遠(yuǎn)的距離,，因此常常被形容為“歌唱”,。除了克氏長(zhǎng)臂猿（Hylobates klossii)和銀灰長(zhǎng)臂猿(H.moloch)之外的所有長(zhǎng)臂猿都會(huì)由雌雄默契配合進(jìn)行“二重唱”。二重唱結(jié)構(gòu)復(fù)雜,，功能多樣,，是長(zhǎng)臂猿研究中非常引人注目的一個(gè)方面。配對(duì)的西黑冠長(zhǎng)臂猿(Nomascus concolor)的二重唱結(jié)構(gòu)穩(wěn)定,，由雄性主導(dǎo),，而且有著極高的雌雄特異性--兩性的鳴叫不論在音調(diào)還是音節(jié)上都沒(méi)有任何重疊。盡管長(zhǎng)臂猿的鳴叫是由基因決定的,，每種長(zhǎng)臂猿都有其固定的鳴叫模式,，但是隨著環(huán)境的變化，其鳴叫也會(huì)表現(xiàn)出一定的可塑性,，這就會(huì)體現(xiàn)在其個(gè)體的差異上,。獸類(lèi)生態(tài)與進(jìn)化研究組的孫國(guó)政博士在導(dǎo)師蔣學(xué)龍研究員的指導(dǎo)下,，對(duì)哀牢山平河以及無(wú)量山大寨子這兩個(gè)研究地點(diǎn)的八個(gè)黑長(zhǎng)臂猿群體中的成年雄性鳴叫特征進(jìn)行了研究對(duì)比,，結(jié)果發(fā)現(xiàn)：同一地點(diǎn)的群體鳴叫特異性很高，可以很容易地與相鄰群體區(qū)別開(kāi)來(lái),。并且同一地點(diǎn)雄性長(zhǎng)臂猿的鳴叫個(gè)體特異性高于兩個(gè)研究地點(diǎn)之間的不同群體間的特異性,。這就說(shuō)明，為了與相鄰群體區(qū)別開(kāi)來(lái),，雄性黑長(zhǎng)臂猿會(huì)積極地進(jìn)行聲音調(diào)節(jié),，來(lái)提高其在當(dāng)?shù)氐穆曇籼禺愋浴＿@是首個(gè)在黑長(zhǎng)臂猿群體中進(jìn)行的聲音特異性研究，填補(bǔ)了以往黑長(zhǎng)臂猿聲音研究的空白（生物谷Bioon.com）

Abstract
This is the first study of vocal individuality in male songs of black crested gibbons. The sound recordings were carried out at two field sites, Pinghe, Ailao Mountains, and Dazhaizi, Wuliang Mountains, both located in Yunnan province, China. A total of 127 coda phrases of 38 male songs bouts of eight individual male gibbons were analyzed. Stepwise discriminant function analysis was used to examine the acoustic individuality of the males. We found that individuality among neighbors was very pronounced. Moreover, individuality within a site (i.e. among neighbors) is higher than among individuals between sites. Our finding suggests that black crested gibbons may actively increase their degree of vocal individuality against that of their immediate neighbors by vocal adjustment. Am. J.
