A study on community structure of macrozoobenthos was conducted in the vicinity of seagrass beds Barrang Lompo Island Waters,Makassar. The aim of this study was to investigate species composition, density of macrozoobenthos in the area.Total of 27 species macrozoobenthos were identified during this study.Modiolus micropterus is the most dominant species with density of 542 individu/m .The highest diversity index was found in southeast side (2.38) while northeast side has diversity index only 0.70. Macrozoobentos composition in both station were different with similarity index of 21%.

BERITA BIOLOGI Vol 7, No 1&2 (2004)
Publisher : Research Center for Biology-Indonesian Institute of Sciences

Studi taksonomi jamur di Taman Nasional Gunung Halimun (TNGH) belum dilakukan dengan intensif.Sebanyak 35 jenis Agarics dikoleksi dari kawasan TNGH meliputi 23 marga dan 9 suku.Kekayaan keanekaragaman jamur ini diperoleh dari eksplorasi di 3 lokasi yaitu Cikaniki, Gunung Botol dan Gunung Telaga (Ciptarasa).Sejumlah sampel belum teridentifikasi karena karakter yang belum jelas.Oleh karena itu, jumlah jenis-jenis baru dari eksplorasi ini belum dapat diketahui.

Vertical distributions of scarabaeids dung beetles (Coleoptera: Scarabaeidae) were studied in a tropical mountaineous rainforest of Gede-Pangrango National Park using human dung traps. Samples were collected at four different altitudes of 500-1000m, 1001-1500, 1501-2000 and 2001-2500m of five different collection sites (Cibodas, Selabintana, Situ Gunung, Bodogol, and Gunung Putri). As many as 1052 individuals of 28 species of scarabaeid dung beetles that belonging to five genera were collected.Onthophagus was the most diverse group, which consists of 21 species (75% of collected species) and followed by Copris with 3 species (10.7%), Paragymnopleurus with 2 species (7.1%), Catharsius with 1 species (3.6%), and Phacosoma with 1 species (3.6%). The Shanon-Winner index of diversity and evenness gradually declined with the increase of altitudes. The different of environment conditions on each altitude might affect to the diversity, abundance, and distribution of dung beetles. The diversity of dung beetles at the interval of 1001-1500m and 1501-2000m were not so high but abundance and similarity were high. Diversity index, evenness, abundance, and species similarity of dung beetles at the interval of 2001-2500m was low because of unfavorable habitat. Although the diversity of dung beetles at the interval 500-1000m was the highest, however abundance and similarity index were relatively low. Analyze of diversity, abundance, evenness, and similarity indexes of dung beetles on each of the different altitudes and environment conditions were discussed in this paper.

Wawonii is one of the small islands located at S.E. Celebes. Plant Diversity and its utilization by the local people have not been recorded yet.Ethnobotanic study has been conducted in several location (Lansilowo, Wawolaa, Lampeapi and Boboloi Districts) visited in 2003-2005, using semi structural interviews and open-ended method. The result of trie study showed that community of this island consist of several ethnics (Bajo, Menui, Muna, Buton, Tolaki. Kolesusu, Jawa and Wawonii).Wawonii is the origin and majority ethnic in this island. About 200 species of plant have been used for their daily need such as for food, utensil, medicine and cosmetic, waving, energy and others.Indigenous knowledge of the local people about the species plant utilization will be discussed.

KAJIAN FITOKIMIA Hopea mengarawan DAN IMPLIKASINYA PADA KEMOTAKSONOMI HOPEA Sahidin, Sahidin; Hakini, EuisH; Syah, Yana M; Juliawaty, Lia D; Achmad, Sjamsul A.; Din, Laily Bin; Latip, Jalifah

Nine resveratrol oligomers have been isolated from the stem bark of Hopea mengarawan i.e. diptoindonesin D (1), balanocarpol (2), ampelopsin A (3), hopeaphuran (4), heimiol A (5), parviflorol (6), a-viniferin (7), isohopeaphenol (8), and vaticanol B (9).The structures of these compounds were determined based on spectroscopic evidence such as UV, IR, 1-D, 2-D NMR and comparison with the reported data. Those compounds implied that Hopea tends to produce resveratrol dimers. Moreover, in subgenus level, besides ampelopsin A (3) and isohopeaphenol (9), resveratrol oligomers in H. mengarawan the same as in H.dryobalanoides. It indicated that H. mengarawan and H. dryobalanoid.es came from the same subgenus.

FLUKTUASI POTENSIAL AIR HARIAN GEWANG {Corypha gebanga Lamk.), JENIS TUMBUHAN HIJAU ABADI DISAVANA NTT Naiola, B Paul

A physiological study on Gewang or Tune (Corypha utan Lamk.),a drought resistant and still-wild native palm species in the savanna area of Timor island, East Nusa Tenggara (NTT),shows that this species undergoes a sharp fluctuation in her diurnal water potential (Wd).In two different sites,the early morning Wd shows a less negative values (-1,9 bars to -5,40 bars); however in the afternoon, due to environmental stresses, the Wd drastically dropped to between (-9,7 bars and -17,3 bars).Interestingly,Gewang successfully regulates her Wd during the afternoon and along the night as their d went back normal levels, due to quickly recharged of their Vd to less negative values (-2,1 bar to -8,5 bars).The values of d differs between two sites, however they have similar patterns when comes to recharge their WA.This phenomenon is in line with their relative water content (RWC), as shown a fluctuation following the drops and recharge of Vd.This figure indicates that Gewang may develop mechanism of osmotic adjustment to cope with environmental especially water stress, thus proves her ability to lead as a drought resistant and evergreen species.

Water is the main parameter to determine whether the yield potential of a plant is obtained or not. Water deficit on the tissue causes the disruption of all chemical process in the plant metabolism resulted in the plant growth impediment.In order to acquire the drought tolerance variety, various efforts have been conducted. Among others, in addition to the selection and characterization of the available germ plasma along with its cross-breeding, the development of the drought tolerance plant is conducted through somaclonal varitype induction. In the cultivation of the drought tolerance plant, beside physiological mechanism and biochemistry related to the plant tolerant to drought, the procedure of the selective and optimal selection should be managed.Hence,the mastery of the optimum selection techniques, in a relatively short time, the new drought tolerance lines could be obtained.

The diversity of the pandan flora from the Lore Lindu National Park has never been reported. Recent floristic study recognised 6 species belonging to Pandanaceae occur in the area. Freycinetia minahassae, F.celebica and Pandanus sarasinorum are the common species found in Sulawesi. Freycinetia oblanceolata and F. polystachya are new records.Freycinetia celebica is rediscovered. The endemic states of F.minahassae and P.sarasinorum are toppled. The extended distribution area of P. gladiator is recorded.

An attempt to produce arbuscular fungi (AF) spore in pot culture from bamboo soil samples collected from Meru Betiri National Park, Jember, East Java and Purwakarta, West Java was carried out by used of Pueraria phaseoloides as a host plant. The result showed nine species of AF i.e. Acaulospora foveata associated with Dendrocalamus asper and Gigantochloa apus, A. scrobiculata associated with D. asper and G. apus, A. tuberculata associated with Bambusa vulgaris, D. asper, Schizostachyum zollingeri, G.manggong and G. apus. Glotnus etunicatum associated with B. vulgaris, D. asper, G. manggong and G. apus while G. fuegianum associated with B. vulgaris, D. asper, S. zollingeri, Glomus cf. formosanum and G. geosporum, associated with D. asper and G. apus. G. mosseae associated with S. zollingeri and G. apus and Scutellospora calospora associated with G. manggong.The association of some species of AF with several species of bamboo in Java found in this study is apparently new record.
