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

Fifty-two isolates were isolated from Gunung Halimun National Park on the basis of morphological and some physiological characteristics.Those isolates were belonged to three groups namely, ascomycetous, basidiomycetous and imperfect yeasts.Rhodotolum sp.was only found in Ciptarasa site at 1500 m asl, ascomycetous yeasts was only isolated from deteoretic root in Gunung Botol site, while Candida sp.(small globose shaped cells) was only isolated from soil at 1800 m asl of Gunung Botol site. Type of plant species appeared has no effect on yeasts diversity as shown by similar yeasts diversity was observed at rhizosphere soil of three dominating plant (Schima waallichii, Castanopsis javanica and Altingia excelsa) at Cikaniki study site.

Abstract

Gunung Halimun National Park is known to be the area of head waters of a number river systems originate. However,there has been no information on fishes diversity at this area.In this regard, a series of ichthyofauna study was conducted from 1996 to 2000. Thirty seven species belonging to 13 families and 26 genera have been found in the rivers and streams in Gunung Halimun National Park and its adjacent area.Gobiidae was dominant, comprising 13 species or 36,36 %, followed by Cyprinidae comprising 5 species or 16.13 %.These Gobioid species were derived from Cisukawayana and Cimaja River, two of the rivers existing in Gunung Halimun National Park which flow south, to the Indian Ocean. In river flowing north i.e, Cikaniki, Ciberang and Cidurian, even from the middle of Cisadane River these fishes were not found. The fishes species which were found in common in rivers flowing north and south were Rasbora aprotaenia,Puntius binotatus, Channa gachua, Clarias batrachus, Poecilia reticulata and Xiphoporus helleri. Up to the present ten fish species were found within the park such as R. aprotaernia, P. binotatus, T. tambra, C. gachua, P. reticulata, P. latipinna, Cyprinus carpio, Monopterus albus, Glyptothorax platypogon and Lentipes sp. It was found that genus Lentipes and Schismatogobius marmoratus extend their range to Java (new record for Java) as well as Rasbora aprotaenia extends its range to southern Java.

Abstract

The population of aerobic cellulolyitic bacteria (ACB) of soil Gunung Halimun National park and its celulolytic capacity were studied.The soil samples were collected from various altitude (500-1500) m asl.Microbial isolation was performed by culture enrichment technique with CMC (carboxymethyl cellulose) as the major carbon sources.The quantitative determination of ACB was performed by growing the microbes on CMC containing media, and utilizing congored as an indicator.ACB was indicated by formation of clearing zone surrounding growing colony.Cellulytic capacity of each isolates was determined by analysing the ratio of colony and clear zone formation.ACB were quite heterogenous include Bacillus sp., Clostridium sp., Chromobacterlum sp., Enterobacter sp., Moraxella sp. and Pseudomonas sp.

Abstract

Study on fluctuation of rainfall and insect community was conducted in a tropical forest, Gunung Halimun National Park. Ten years rainfall data was available to discuss their fluctuations. Rainfall was relatively non-seasonal with high number of almost entire monthly rainfalls.Although fluctuation of rainfall in GHNP did not show clear seasonal trend, however appearance of less rainfall showed from June to September. There were several slight fluctuations in the number of rainfalls from a month to another and some time showed major and minor peaks. Monthly dry months had never reached 0 mm. In ordinary years, only one-month drought occurred in July 1991 (90 mm) and December 2000 (8 mm). Strong drought occurred only during El Nino of 1994 and 1997, which have 3 to 4 dry months. Fluctuation of insect community was studied from March 2000 up to February 2001. Two insect collection methods were applied by setting up light traps and pitfall traps. Total individual of each order of insect counted monthly and to be compared one to another. Changing the number of monthly individual of each order was interpreted to the number of monthly rainfall in order to analyze the relation of changing of the number of rainfall and the individual of each order of the insect collected. Fluctuation of the number of monthly rainfall was synchronous to the number of insect community collected by light traps (night flying insect) but tend to opposite to the number of insect collected by pitfall traps (ground insect).

Abstract

Inventory Trichosanthes L. in Gunung Halimun Nasional Park have been conducted. Seven species recorded occuring in TN Gn.Halimun namely, T. montana, T. ovigera, T. pubera, T. quinquangulata, T. tricuspidata, T. villosa, and T. wawrae.These species are found mostly in humid area in edge forest, or along river sides. Trichosanthes wawrae was found in Cikaniki,whereas the other six species found in Corridor Cianten. Trichosanthes quinquangulata has widelydistributed, it has found in Cibanteng and Leuwijamang as well. Exploration is still continuing to study the distribution of this genus in Gn. Halimun, to recollect the rare species and to do phylogenetic analysis.
