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

ABSTRACTSurra is a parasitic disease caused by T. evansi and causing high economic losses in Indonesia. Some isolates have been isolated from several areas experiencing outbreaks of Surra in Indonesia. The isolates have been reported to have a diversity of protein profiles based on SDS PAGE (sodium dodecyl sulphate polyacrilamide gel electrophoresis). The research aims to identify immunogenic protein from each isolate and make the selection of T. evansi isolates which is potential as a source of antigens for immunoassay development. Each isolates were obtained to be purified from blood and then the protein was isolated. The proteins were run onto polyacrylamide gel electrophoresis and visualized by Coomassie blue. Another electrophoresis results were transferred onto a nitrocellulose membrane for immunoblotting. The results showed that the immunogenic proteins that consistently detected among nine T. evansi isolates of Indonesia are 100, 90, 85, 76-80, 70, 65, 55, 49-52, 44-46, 40, 34-36, 31 -33 kDa. Among the nine T. evansi isolates, N372 isolate was selected as a candidate for immunoasay development, especially ELISA. Immunogenic proteins were specifically found on the N372 isolate are 85, 70, 65, 49-52, 44-46, 34-36, 31-33, 24-28, 15-20 kDa.Keywords : Trypanosoma evansi, immunoblotting, protein profiles, immunogenic protein

Abstract

Hylarana celebensis (Peters, 1872) is an endemic frog to Sulawesi, the species being a member of family Ranidae.  The presence of the frog in its habitat is easily detected from its advertisement call; males usually call in a chorus, they call to each other in a large group. Bioacoustics of calls that a typical individual male of H. celebensis has not been described in detail, although it is very easy to find this species in freshwater swamps, permanent ponds, or slow-flowing waters in the lowland areas. The purpose of the bioacoustic analysis on H. celebensis?s calls that were recorded at Bahodopi area is to build a reference collection to be compared with H. celebensis?s bioacoustics to the other regions in Sulawesi. Because of the wide distribution of this frog in Sulawesi; population genetic structure of H. celebensis may also follow the population genetic structure of Ingerophrynus celebensis. Calls of H. celebensis have two types of calls, i.e. pure tone and pulse; however, pure tones have three variation, namely pure tone type 1, pure tone type 2 and pure tone type 3; however pulsed call has only one type. Keywords: Anura, Hylarana celebensis, bioacoustics, Sulawesi.

Abstract

ABSTRACTTaro (Colocasia esculenta (L.) Schot.) has been cultivated for a long time in Indonesia. Taro tuber can be used as alternative food for rice substitute to support food diversification program. Taro cv. Bentul is preferable to farmers because it has few buds that are easy to maintain and adaptable in both lowlands and highlands. Its tuber has a delicious taste and a soft texture. Somatic cell manipulation of Indonesian taro through biotechnology may contribute to increase its productivity. One of in vitro technique for somatic cell manipulation is polyploidy. Oryzalin has been able to obtain taro cv. Bentul tetraploid. A total of 17 tetraploid clones were used in this study for clustering. Those clones were obtained from previous research and have stable ploidy level. The objective of this study was to determine cluster Bentul tetraploid of shoot culture using Ward method based on their in vitro growth as an initial selection before further selection in the field. Shoot tips of tetraploid were cultured on MS medium containing 2 mg/l BAP, 1 mg/l thiamine and 2 mg/l adenine for 6 weeks. The observed growth variables were number of shoots, length of petiole, number of leaves and roots. The clusterring was done using Ward and Euclidean Distance method followed by Analysis of Varians and Duncan Multiple Range Tests (DMRT). Out of 17 clones observed resulted in 3 clusters. Cluster 1 consisted of 2 clones, cluster 2 consisted of 9 clones, and cluster 3 consisted of 6 clones respectively. The best cluster was cluster 3 which was significantly different on the average number of shoots and leaves. Cluster 3 was dominated by clones derived from oryzalin at 75 ?M.Keywords: taro (Colocasia esculenta (L.) Schot.), tetraploid, in vitro growth, cluster analysis, Ward
