Abstract

Javan langur is protected spesies of primates that highly threatened. Habitat degradation as a major threat causes javan langur Trachypithecus auratus (E. Geoffroy 1812) populations living in isolated habitat fragments. The research was carried out to determine the daily movement of javan langur in TWAGP as form of adaptation in isolated habitat fragments. The study was conducted in May-June 2012 by using focal animal sampling method. Vegetation analysis was performed with a point centered quarter method. The results showed that there were three major land cover types used by the Javan langur, i.e. forest, transitional forest-cultivation and cultivation. The dominant activity occurred in transisional forest-cultivation habitat (48.19%). The highest proportion of activity wass resting (33.65%) followed by feeding (30.68%), moving (27.08%) and social activities (8.60%). Based on the variations of vegetation strata, the dominant activity performed at stratum C(4-20 meters) accounted for 80.07%.

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.

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

Bats utilizing resources together will differ morphologically, ecologically, and behaviorally. This study aimed to measurespecies diversity and to investigate resource use by Megachiropteran bats. Data were analyzed using Principal ComponentAnalysis (PCA), Canonical Correspondence Analysis (CCA), Correspondence Analysis (CA), euclidean distance, chisquare, Anova, and niche overlap index. The result showed seven bat species were captured in three habitat types. Plant asfood identified from pollen comprised 55 species from 29 families and 11 types of corolla. Dobsonia magna and Rousettusamplexicaudatus preferred mixed fruit plantation, whilst other bat species tended to choose primary forest. Dobsonia minortended to have high niche overlap against Macroglossus minimus and Nyctemene aello. According to similarity of foodresource niche, Dobsonia magna, Dobsonia minor, and Macroglossus minimus tended to closely associate, in contrast,Rousettus amplexicaudatus, Nyctemene albiventer, Nyctemene aello, and Syconicteris australis were groupedcorrespondingly. Niche overlap index of food resource among bat species were overall less than 50%. This indicated thatthere was no interspecies competition to food resource. Coronoid process height (CPH), maximum zygomatic breadth(MZB), and condyle to canine bite point (CC) were craniodental morphology variables which did not describe certaincorolla types.Keywords: species diversity, resource use, niche overlap, Megachiropteran, Gunung Meja

Abstract

ABSTRACTMammalian Diversity Based on Altitudinal Range at Gunung Ciremai NationalPark. Gunung Ciremai was declared as national park in 2004. As a new national park,the mammalian data is lacking especially about mammalian diversity based on vegetationcomposition and altitudinal in Gunung Ciremai. The observation was conducted in 4habitats, such as: pine forest, lowland forest, mountain forest and subalpine forest elevationfrom 500 to 3078 m asl. Number of species found are 9 (7 species was through directobservation and 2 specis by indirect observation). Species richness index is 1,04; speciesdiversity index is 1,00 and species evennes index is 0,52. Relationship between mammaliandiversity and vegetation composition, that is sapling density, poles density and tree densityshowing significant value just for sapling density (r2= 0,501 dan p= 0,044). Relationshipbetween mammalian diversity and altitudinal show significant value (r2= 0,881 and P=0,025).Key words: mammalian diversity, habitat, vegetation composition and altitudinal

Abstract

ABSTRACTThe analysis of palm and sole arschitexture dermatographic traits have been done for two sub genera of Hylobates and Symphalangus in Indonesia. A dermatographical study was conducted to specimens from Indonesia Archipelago on genera Hylobates and Symphalangus, which are deposited in Museum Zoologicum Bogoriense-LIPI. A total of 101 specimens of Hylobates (78 specimens) and Symphalangus (23 specimens) were examined on palm and sole dermatographic traits. The discriminant canonical analyses showed that the Indonesian gibbon has two differences in function space of dermatograph types. By plotting these data, the percentage of the two groups that correctly classified was calculated to be 90.63%. Only nine specimens of Hylobates and Symphalangus were incorrectly classified, seven (9.5%) specimens Hylobates were classified as Symphalangus, and two specimens Symphalangus (9.1%) were classified as Hylobates. The majority of loops type dermatograph in this study indicated that the traits direction to ulnar, radial, and proximal between Hylobates and Symphalangus are significantly different (X2 >0.05, df=3; X2 = 13.58, 10.03 and 7.91 respectively).Keywords: Architecture Dermatographic, Hylobates, Symphalangus

Abstract

ABSTRACTThe Grouping of Fruit Bats Based on Pollend Type Characterized as Food Resources inBogor Botanical Garden, Indonesia. A study was conducted to identify pollen consummedby fruits bat in Bogor Botanical Garden from March 2008 to June 2009. The types of crown ofthe flower, pollen and pollen size which chosen by fruit bats were analysed by using highdetrended canonical correspondent. The result indicated that there are three major groups ofbats based on the similarities of food type or flower resources consumed by fruit bats. Thegroups were (1) males of Macroglossus sobrinus and the females of Eonycteris spelaea, (2)Cynopterus brachyotis and the females of C. minutus, and (3) males and females of C.titthaheileus, females of C. brachyotis and Macroglossus sobrinus, males of C. sphinx and C.minutus, and females of C. sphinx.Key words: Megachiroptera, pollend, seed distribution,
