我们评估了2001年11月至2002年4月，在两个热带雨林地区，Brahadri-Makut和Sirsi Honnavara，西高止山脉，印度南部，哺乳动物的分布和相对丰度。直接（白天和夜间野生动物目击通过'recky'散步）和间接（野生动物的迹象和当地的信息）的方法。这两个地区共有34-35种，其中我们记录了31-32种; 14种属于世界自然保护联盟红色名录中的受威胁类别，6种是印度特有的。只有三个物种（黑叶猴、狮尾猕猴和亚洲象）的分布和相对丰度受生态因素的影响。其他10种大型哺乳动物在锡尔西-洪纳瓦拉比在布拉哈里-马库特更常见，而9种小型哺乳动物中的大多数在布拉哈里-马库特更常见。这些差异可以归因于不同的狩猎做法，而不是生态或地理因素。在布拉哈里-马库特，主要是白天用枪狩猎，对大型昼行哺乳动物的影响最大，而在锡西-洪纳瓦拉，主要是夜间用陷阱狩猎，避免灵长类动物，对小型夜间哺乳动物的影响更大。布拉哈里-马库特是西高止山脉少数几个仍然可以找到印度南部所有灵长类物种的地区之一，但该地区没有受到任何官方保护。在锡尔西-洪纳瓦拉，农业的侵蚀是一种常规做法，剩下的森林只存在于狭窄的带状网络中。
We assessed the distribution and relative abundance of mammals in two rainforest areas, Brahmagiri-Makut and Sirsi-Honnavara, of the Western Ghats, southern India, from November 2001 to April 2002. Both direct (daytime and night-time wildlife sightings through ‘recky’ walks) and indirect (wildlife signs and local information) methods were employed. A total of 34–35 species, of which we recorded 31–32, are known from the two areas; 14 are in one of the IUCN Red List threatened categories and six are endemic to India. Ecological factors account for the distribution and relative abundance of only three species (Nilgiri langur Semnopithecus johnii, lion-tailed macaque Macaca silenus and Asiatic elephant Elephas maximus). Ten other large species of mammals were more common in Sirsi-Honnavara than in Brahmagiri-Makut, whereas most of nine smaller species were generally more common in Brahmagiri-Makut. These differences can be attributed to different hunting practices rather than to ecological or biogeographical factors. In Brahmagiri-Makut the mainly daytime hunting using guns has the greatest impact on large diurnal mammals, whereas in Sirsi-Honnavara the mostly night-time hunting with traps, and avoidance of primates, has a greater effect on small nocturnal mammals. Brahmagiri-Makut is one of the few areas in the Western Ghats where all of the primate species of southern India can still be found, but the area does not receive any official protection. In Sirsi-Honnavara encroachment of agriculture is a regular practice, and the remaining forests exist only as a network of narrow strips.
