具有多洞穴特点的喀斯特和火山熔岩地貌具有较多的翼手目种类，但红层地貌由于分布于南方和分散分布的特点而具有最高的翼手目种数密度[动物学报51（3）：413-4222005]。

Although more Chiroptera species distribute Karst and Volcano lava physiognomies reasonably due to caves for inhabiting , red beds have highest species density of Chiroptera , perhaps seasonably due to its southern distribution and patched dispersion .

基于这项研究，我认为只有通过对自然变异的长期、细致的观察，才能发现行为生态中细微变化，才能解释、或者预测人为影响对自然干扰的底限[动物学报51（5）：821-8292005]。

It is only by such intensive long-term study of natural variation that the subtleties of behavioural ecology can be interpreted , generating the natural baseline against which anthropogenic impacts can be interpreted , or from which they may be predicted .
