Abstract

The arrival of human und their activities on protected areas will be a problem causing habitat degradation in quality due to cutting of trees,hunting and noising.This research was conducted to observe the difference of responses of primates to the arrival of human on disturbed and undisturbed forest in Cikaniki area,Mount Halimun National Park. Primates responses to environmental changes will be detected from vigilance behaviour in the form of early detection and reactions.The results of this research indicated that the three species of primates in Cikaniki area (javan gibbon, javan langur, and grizzled langur) generally detected early to the observers arrival compared to the observer himself detecting the position of primates.The early detection of the three species of primates is slower in disturbed forest compared to the undisturbed one.Furthermore,the reactions of these three species generally negative;although sometimes they response neutrally, but none was positive response in both disturbed and undisturbed forest. This behaviour indicated that although the primates have been adapted to the presence of human (early detection: slower in disturbed forest), but they still vigilant to the presence of human with negative responses.

Abstract

Giam Siak Kecil Bukit Batu is a biosphere reserve which one of its functions is as a habitat for wildlife. However, biodiversity data in the Giam Siak Kecil Bukit Batu Biosphere Reserve (GSKBB-BR) is still very minimal, including insects (Coleoptera and Hemiptera). This research was conducted to determine the diversity of Coleoptera and Hemiptera in the GSKBB Biosphere Reserve, Riau, Indonesia. The research was carried out using an exploratory method using "lights trap". The results of the study found 30 species, from 11 families of the order Coleoptera (23 species) and Hemiptera (7 species) in the GSKBB-BR. The diversity index of Coleoptera and Hemiptera at the observation site was moderate (H = 2.73), with a high evenness index (0.80). Scarabaeidae (order Coleoptera) is the family with the highest number of species found (8 species), while the most abundant species were Tibicen linnei and Pomponia fusca (Cicadidae/Hemiptera). Based on their functional roles, Coleoptera and Hemiptera with the highest number are herbivores (17 species), followed by predators (7 species) and decomposers (3 species). The range of values for temperature and humidity at the research site are in normal conditions. The GSKBB-BR area is an important remaining habitat for wildlife in Riau, including various types of insects (Coleoptera and Hemiptera); whose potential still needs to be revealed, and must be managed properly.
