Abstract

A study on the distribution and abundance of high mountain rat was carried out at Gunung Botol, Gunung Halimun National Park.Observation was conducted at three stations located at the mountain top, middle and foot of the mountain.The results indicated that four species of rat were recorded from Gunung Botol, namely Maxomys bartelsii,Niviventer lepturus, Niviventer fulvescens and Niviventer cremoriventer.Our data showed a relationship between number of individuals observed of each species with altitudinal gradients.While estimation of murid rodent population between altitudinal changes indicated there was no differences between the stations observed. An analysis was conducted to investigate any possible association between rat abundance against environment factors that could associate with altitude.The results indicated that ground covering and tree circumference, as well as interspecific competition seemed to be important factors in influencing the differences in distribution of each rat species.

Abstract

Citanduy watershed is one of major watersheds in Java that located through north to south covering four regencies, these are: Ciamis, Tasikmalaya, Garut and Cilacap. As a consequences of environmental changes, this watershed that covering an are about 473.967 ha has faced in deterioration on its roles. This research was aimed to study on the distribution of small mammals at the upper of Citanduy watershed according to their habitat and altitudinal changes. Results indicated that 20 species of small mammals clustered in three groups of habitat. Group 1 consisted of small mammals that occupied the habitat of mixed pines-calliandra. Group 2 comprised of small mammals lived at secondary forest, bambu plantation, and mixed secondary forest-bamboo; and group 3 were mainly occupied shrub. In addtion, an altitude was also affected the distribution of small mammals in the area surveyed. The results of this study are to be used as a basic information that describe the quality of upper Citanduy watershed.
