Abstract

ABSTRACTPollinator Bat Identification Based on Pollen as Feed Resources at LinggarjatiDistrict-Ciremai National Park, West Jawa. Pollen identification that used for feedresources by six species of frugivorous bats from Ciremai National Park was identifiedunder microscope. The results shown that are known 21 species as important plants forbats and in the contrast possibly for bats as pollinator. By the principle componentanalysis and cluster grouping based on Euclidian distance indicated that Aethalops alecto,Chironax melanocephalus as important polinator role in primary forest and high in elevationlevel, C. brachyotis and Macroglossus sobrinus in secondary or fragmented forest andMegaerops kusnotoi in lower primary forest and Cynopterus tittacheilus is important rolefor intermediate area between primary and secondary forest and at lower elevation range.On the niche overlaps analysis indicated that the highest overlaps were known in C.brachyotis and M. sobrinus (0.881) but the lowest in niche overlaps between M. sobrinusand C. melanocephalus (0.288)Key words: pollen, bats, feed resources

Abstract

ABSTRACTThe study on population dynamic and  roosting trees damage by flying fox was conducted for 16 months (March 2008-June 2009) in Bogor Botanical Garden.  Recording of individual flying fox was carried out by use direct observation in the roosting trees habitat at 9.00-15.00, with one replication every week. The result indicated that in 2008 the total flying fox were 420 individuals and in 2009 were 563 individuals (160 juveniles, 218 adult females and 185 adult males). The natality and mortality rate in this location is 0.0214 and 0.0099 respectively. The flying fox population growth can be predicted using exponential equation is N(t+1)=563(1.8395)t.  The study also indicated that in the KRB there are 9 individual trees which are the main perch, 2 individual trees of Pterodotus alata, Pterocarpus indicus, and Shorea leprosula, and each 1 individual tree of the species  Dipterocarpus cornutus, Ficus drupacea, and Syzygium syzygioides. The extent of damage to the tree where the perch is very dependent on the diameter of the canopy, bat population size in one tree, and time periods per roosting season.  Keywords: Population Dynamic, Flying Fox (Pteropus vampyrus), Bogor Botanical Garden

Abstract

ABSTRACTErythrocyt and Haemoglobin on Cave Bat at Gombong Karst Area, Kebumen Regency, CentralJawa. The purpose of this study was observe physiological adaptation of the cave batsconducted from September 2009 to March 2010 in twelve caves within the karst of Gombong,Kebumen Regency, Central Java. In each caves where the bats roosting, temperature, alsohumidity, oxygen percentage in the air, and ammonia content were measured. Three individualsamples were caught from every bat roost during the day when the bats were staying in theirroosts. Then the amount of erythrocyte was counted by hemocytometer and hemoglobincontent was measured using Sahli's method. The data were analyzed using RDA and multipleregressions. It was concluded that humidity, temperature, oxygen and ammonia correlatedsignificantly with erythrocyte and hemoglobin content. The amount of erythrocyte increasedby increasing humvel.Keywords: Bat, cave, erythrocyte, haemoglobin.

Abstract

The study of mammalian diversity was done at Pasir Mayang, Pancuran Gading and Kuamang Kuning - Muara Bungo, Jambi in six different vegetation types, namely primary forest, logged over area or secondary forest, Parasarienthes falcataria plantation, rubber plantation, and jungle rubber forest; each of it was contiguous each other, and the last area was grass land-cassava type area, which were laid on about 10 km of South East to other types. To predict the effect of different habitat types on mammals diversity we used the Linetransect methods. By using the reconnaissance methods, species and number of individual for each species was recorded. The results showed that there were 20 species of mammals at the six habitat types. The highest diversity was on logged overlsecondary forest and the lowest was grass land-cassava area. Based on species richness indices, it was indicated that jungle rubber and logged over area had 10.OO?higher than primary forest. The equality of rank community index between primary forest and logged over area were 55.56%. Based on cluster analysis, there were three groups of habitats used by mammalians. The first group was jungle rubber; second were rubber plantation, cassava-grass land area, and Parasarienthes falcataria plantation; and third was primary-secondary/logged over area Keywords : mammalian, forest plantation, microbiogeography, habitat, Hylobates sp.

Abstract

Insectivorus bat have an important ecological role as biological control for nocturnal insect population. Oneindividual insectivorus bat eats up to 600 individuals' number of insect in an hour. Insectovorus bat from Microchiroptera sub order, dependent on intact expanses for forest. Nowdays, forest as a bat habitat has severe loss caused by logging, forest conversion, and fire, which in turn lead to a decrease habitat quality and quantity. Diversity of Microchiroptera was investigated in an intact forest and secondary forset which burnt in 1997, in Way Canguk Research Station at Bukit Barisan Selatan National Park from June to December 2007. The total sampling effort using harp trap were95 traps night, investigating on each habitat using four harp traps. This study captured 1723 individuals of 19 species and five families consisct of 1382 individuals of 19 species in intact primary forest and 341 individulas of 15 species in seconderay forest. Bat family was caught in this study are Hipposideridae, Vespertilionidae, Rhinolophidae, Megadermatidae, and Nyteridae. Shannon's diversity index in secondary forest is 2.0527±0.0026 higher than primary forest (1.5424±0.0012). The K. intermedia, M. cyclotis, R. trifoliatus, and H. diadema species are only found in primary forest. H. larvatus is the insectivorus bat species most abundance in Way-Canguk Station Research.

Abstract

The study on the specimens of Masked Flying Fox, Pteropus personatus from Gag and Moluccas Islands, Indonesia was conducted by using morphological and genetic analyses. Morphologically, the specimens from Gag are different from the other populations in Moluccas Islands by the smaller size of skull, dental and other external measurements. Based on the measurements of the specimens, the population from Gag Island is identified as P. personatus acityae n. subsp. The phylogenetic reconstruction based on partial cytochrome b sequences also support the differences between P. personatus acityae n. subsp and Pteropus personatus personatus. Thus, recently two subspecies of P. personatus are recognised from its distribution areas.

Abstract

The study of daily activity of (Hylobates moloch Audebert 1798) was conducted in Cikaniki. Ciawitali and Pasir Bivak TN Gunung Halimun for two months from June to July 1999.Commontly the daily activity for Jawan Gibbon are resting 39.1%, feeding 30.3%, moving 24.1% and other social activity 6.5% in average.Based on the meaning of activity category, the most for feeding;activity used by subadult (45%), moving for juvenile (33%), resting for infant (82%) and social for juvenile (15.72%).The least social activity was done by subadult category (0.4%). The space area for Jawan Gibbon activity was done at 5-15 meter (23%), 16-25 meter (43%), 26-35 meter (30%) and upper or top canopy at 35 meter from ground (4%).On this study also indicated that this gibbon turn down until to 1.5 meter from ground at lepus (Ammonium pseudopoetens) vegetation.

Abstract

Examination of morphological variation on Maxomys surifer from Sumatra, Jawa and Kalimantan were conducted using 60 adult specimens.Univariate and multivariate statistical analyses of 20 skull and four external characters showed that Maxomys surifer was not sexually dimorphic (P >0.05). The discriminant analysis based on skull characters indicated that Sumatran population had two distinct group; north (Ketambe and Tapanuli) and South to Central Sumatra, the north of Sumatra form was closer to Kalimantan and Jawa.
