Abstract

Long-tailed macaque (Macaca fascicularis) is one of the non human primates which is widely distributed. Long-tailed macaques live in a group consisted of multimales and multifemales. The group size was determined by predator, food resources, and foraging efficiency. Bumi Perkemahan Pramuka Cibubur is a habitat for long-tailed macaques. This place is a camp area and tourism site, which is predominated by akasia (Acacia auriculiformis). This research is aimed to study feeding activity of long-tailed macaque in Bumi Perkemahan Pramuka, Cibubur, Jakarta. Methods used in this research were habituation, census, ad libitum sampling, focal animal sampling, and scan sampling. The identification of food items was carried out by means of direct observation, interview, specimen collection, and identification of plant species. Feeding activities of long-tailed macaques constituted 9.01% of the total daily activities. Food consumed consists of natural and non natural food. Natural food items were leaf buds of awi tali (Gigantochloa apus) 34.76%, jukut pait (Axonopus compressus) 22.61%, and fig (Ficus benjamina) 7.15%, respectively. Furthermore, non natural food items were food leftovers of visitors 29.00% and peanuts 15.52%, respectively. In general, natural food (74.02%) was consumed more frequent than those of non natural food (25.98%).

Abstract

The comprehensive revision of the genus has been done in the Malay Peninsula, New Guinea, Sumatra andKalimantan. In Java, the revision of Licuala has never been recently completed. This study was based onmorphological characters of specimens which are preserved in Herbarium Bogoriense. The several living collectionscultivated in Bogor Botanical Garden were studied. The aim of this study is to ascertain the correct names andimprove the species delimitation of Licuala in Java. The result shows that there are three species of Licuala inJava. They are L. gracilis, L. pumila and L. spinosa. Two previously known species have been placed into synonymies;L. flabellum to L. gracilis, and L. spectabilis to L. spinosa. Licuala gracilis is endemic for west Java.

Abstract

Disturbances caused by the conversion of rain forests into agricultural systems provide an opportunity for the expansion of Invasive Plant Species (IPS). Bukit Duabelas National Park is one of the few remaining lowland forests in Jambi Province (Sumatera, Indonesia). The surrounding areas up to the national park borders have already been converted into jungle rubber agroforests as well as rubber and oil palm plantations which might lead to an increased spread of IPS into the forest. This study was aimed at compiling a list of IPS and determining their distribution and coverage of IPS in four land use systems (rain forest jungle rubber, rubber and oil palm plantations). Spatial distribution patterns were investigated by creating a horizontal vegetation profile diagram for the permanent plots of the EFForTS project (Ecological and Socioeconomic Functions of Tropical Lowland Rainforest Transformation Systems, http://www.uni-goettingen.de/crc990). The dominance of IPS was determined using Important Value Index. A total of forty IPS were identified across the four land-use systems. The numbers of IPS were the highest in oil palm (28 species) and rubber plantations (27 species), and the lowest in jungle rubber (10 species). IPS were absent in the lowland rain forest. The diversity of IPS was influenced by environmental factors, especially canopy openness. IPS with the highest ground coverage were Dicranopteris linearis and Clidemia hirta. Both of them were found in all three land-use systems outside the rain forest when the forest canopy opens due to illegal logging or other human disturbances. Therefore, reforestation of disturbed areas is recommended to prevent the spread of IPS.
