Abstract

An ecological study was conducted to assess the occurrences of rhizosphere fungi in three dominating trees (Altingia excelsa, Schima wallichii and Castanopsis javanica) within Gunung Halimun National Park.Rhizosphere trees in Gunung Halimun National Park was mainly dominated by Trichoderma (47%), followed by Penicillium (16%), Cunninghamella (10%),Mortierella (15%),Acremonium (7%), and Humicola (6%).Similar composition of rhizosphere fungi was shown by the three trees and mainly consisted of Trichoderma and Penicillium.There was negative correlation of rhizosphere to fungal composition which was shown by C.javanicus and the positive correlation was shown by A. excelsa and S. wallichii.Based on total of fungi encountered, Trichoderma was found to be the most common and dominant fungus in rhizosphere of those trees.Other fungi were also considered common were Penicillium, Mortierella, Cunninghamella, Acremonium and Humicola. Based on the number of samples, the frequency of the occurrence of Trichoderma was the highest (100%), followed by Penicillium (88%),Cunninghamella (59%), Humicola (47%), Acremonium (41%), Mortierella (35%), Verticillium (18%), Cylindrocladium (12%), Aspergillus (6%), and Gliocephalotrichum (6%).

Abstract

Although the role of raptors as the top predators in the food chain is important to maintain the balance of an ecosystem, in Indonesia they have rarely been studied.This paper presents the most comprehensive study on the diversity and distribution of raptors with emphasize on Javan Hawk-eagle at Gunung Halimun National Park, the largest remnant forest in Java.The raptor study has been done by field surveys,long watches at selected observation sites and collecting information from previous reports.The results showed that there are 17 raptor species recorded in the area.Furthermore, the Crested Serpent eagle (Spilornis cheelo),Black Eagle (Ictinaetus malayensis), and Javan Hawk-eagle {Spizaetus bartelsi) were recorded in many locations.However,the Black-winged Kite {Elanus caeruleus), Brahminy Kite (Haliastur Indus), Lesser Fish-eagle (Ichthyophaga ichthyaetus),Japanese Sparrowhawk (Accipiter gularis) and the White-bellied sea-eagle (Haliaeetus leucogaster) were observed only in one location. In addition, the Javan Hawk-eagle was recorded at 14 locations namely G. Halimun Utara, G. Buligir Putih, Pasir Cangkuang, G. Malang, West Halimun, G. Bodas, G. Tumpeng, G. Citimur, G. Bengreng, G. Batu, Cadas Mahpar, G. Kempul, G. Kendeng and G. Botol.The number of observed Javan Hawk-eagle individuals at G. Botol was higher than in other locations.

Abstract

Diptera is one of the four largest orders of insects (the three others are Coleoptera, Lepidoptera and Hymenoptera).Presently, about 108 families of Diptera were recoqnized and over 150.000 species have been described worldwide.This study was conducted to explore the diversity of Diptera in Gunung Halimun National Park, West Java.Sampling of Diptera has been conducted in Mt. Kendeng (1.200 - 1.300 m asl) and mount Botol (1.650 and 1.750 m asl) using yellow pan traps, Malaise traps, light traps, and sweep nets. The diversity of Diptera were analyzed using Shannon's diversity index and evenness, and Jaccard's similarity index (Magurran 1987). In this study, we found 49 families of Diptera (12 families are Nematocera and 37 families are Brachycera). The diversity of Diptera in Mt. Kendeng was higher (Shannon diversity index; H' =2.92) than that in Mt. Botol (H' = 2.46). The similarity of Diptera in Mt. Kendeng and Mt. Botol was 60%(Jaccard's similarity index; Cj=0.6).

Abstract

The biodiversity of nitrogen fixing bacteria (Rhizobium, Azotobacter and Azospirillum) and phosphate solubilizing bacteria in rhizosphere collected from Gunung Halimun National Park were studied.Bacterial population was counted from soil rhizosphere collected from various ecosystem types (determined based on elevation) namely 600 m, 1000 m, 1100 m, 1500 m and 1800 m above sea level.The results showed that the highest population of N-fixing and P solubilizing bacteria at Cikaniki (1100 asl) are founded in the plant rhizosphere of Schima wallichii in plot Suzuki A I and Altingia exelsa in Suzuki A III,at Gunung Botol area is in 1000 m asl,and Ciptarasa area is in 600 m asl.The population of N-fixing and P solubilizing bacteria at Gunung Halimun was influenced by the vegetation type, soil pH,and the elevation of area. Rhizobium, Azotobacter, Azospirillum (N-fixing bacteria); Pseudomonas sp, and Bacillus megaterium (P solubilizing bacteria), are most dominant at 600 m, 1000 m and 1100 m asl.

Abstract

This study was conducted to know of potential of natural resources of Mt.Halimun used by surrounding communities and the development of bufferzone.The potential of natural resources are composed of wildlife, plant biodiversity,land and hydrology.Then, The utilization of natural resources will be correlated with the condition of socio economic and culture of communities.According to the study, it is known that the major occupation of the village communities are as farmers, who have private land or as laborers (>50%). As laborers, they worked for landlord with salary Rp. 5,000 to Rp 10,000 per day for six days per week. This condition made village communities to depend their livelihood to potential of natural resources of Mt. Halimun NP. Based on dynamic hypothesis,the bufferzone could be developed through data and information of the natural resources that utilized or disturbed by communities. The plant biodiversity are used as energy, traditional medicines, food, handicrafts and forages.Illegal hunting done by surrounding communities was hunting wild pigs, birds and monkeys.To limit the exploitation, illegal cutting, illegal hunting and deforestation The Mt Halimun NP have program social forestry and agroforestry to decrease dependency of communities to the forest. For example the sheep breeding with forage plants in bufferzone.Other programs such as goats breeding and fish or plants development could be done in border land of national park or private land of communities.
