DISTRIBUSI VERTIKAL KOMUNITAS KUMBANG KOTORAN Scarabaeidae DI HABITAT TAMAN NASIONAL GUNUNG SALAK

Abstract

Scarabaeidae dung beettles is a bioindicator through its function as decomposer, Scrabaeidae maintains the balance of environmental conditions that represented by the variation community structures. A study of Scarabaeidae was conducted to observe the variation of community structures related to different heights (900, 1400 dan 2000 masl) in Salak Halimun Mountains National Park (TNGHS), West Java. Pit Fall Dung Trap method was applied in a belt transect paralele with tracking line. In every height , there were 5 traps created with 10 meters distance among each other. In addition, the study also measured main abiotic paramters, such as type of susbtrate, soil acidity, soil temperature that presumed to have strong influence in establishment of the communities. The result showed that there was a variation in community structures related to different heights. In 900 masl, diversity index (H’) was 0.80 which caterogised as low, in 1400 masl, H’= 1,29 (middle) and H’=0,84 (low) was found in the 2000 masl. The community structures of Scarabaeidae in TNGHS were made up by genus of Onthophagus dan Copris that conssits of 4 (four) spesies, they were O. taurus, O. semicupreus, O. babirussoides dan Copris punctulatus. Onthophagus taurus considered as dominant species that filled 60 % or 339 individual of the communities. Meanwhile, Onthopagus babirussoides can be considered as rare species which only 8% been caught during study.
