Abstract

Diversity and vertical distributions of scarabaeids dungbeetles (Coleoptera: Scarabaeidae) were studied in a tropical mountaineous rainforest of Gede Pangrango National Park using dung traps. Samples were collected at four altitudes of 500-1000m, 1001-1500, 1501- 2000, and 2001-2500m of five different collection sites (Cibodas, Selabintana, Situ Gunung, Bodogol, and Gunung Putri). 1052 individuals of 28 species of scarabaeid dungbeetles that belongs to five genus were collected. The most diverse groub was the genus Onthophagus, which consists of 21 species (75% of collected species) and followed by Copris with 3 species (10.7%), Paragymnopleurus with 2 species (7.1%), Catarsius with 1 species (3.6%), and Phacosoma with 1 species (3.6%). The Shanon-Winner index of diversity and evenness were gradually declining during the time when altitudes were increasing. Altitude was an important factor in the diversity, abundance, and distribution of dungbeetles. The diversity of dungbeetles 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 dungbeetles at the interval of 2001-2500m was low because of unfavourable habitat. Although the diversity of dungbeetles at the interval 500-1000m was the highest, however abundance and similarity index were relatively low. Analyse of diversity, abundance, evenness, and similarity of dungbeetles on each of the different altitudes and environment conditions were discussed in this paper.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: diversity, vertical distributions, scarabaeid dungbeetles, Gede Pangrango National Park, Wawonii Island.

Abstract

Every species of soil macrofauna prefer specific food and environment to be establish in it's habitat. Their diversity depend on variation of food and environmental condition. The aim of this research was to study the effect of different crop residue and light intensity on population of several soil macrofauna specieses. Mycrocosmos experiment was arranged in split-plot design with two treatments factor, i.e.: (1) crop residue (albizia, papaya, elephant grass, maize, sweet potato and without crop residue input), and (2) light intensities (0, 5, 15 and 25) Watt/day. The soil macrofauna were earthworms, millipedes, scarabids larvae and cocroachs.Results of the study showed that: (1) crop residues apllication increased soil macrofauna population, especially maize residue ( by 113%, respectively, compare to control tretment), (2) on higher light intensity, population of earthworms, scarabids larvae and cocroach decreased, but population of millipedes increased, (3) the highest macrofauna population was on maize residue and 5 Watt/day light intensity treatment.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Soil macrofauna, preferency, crop residue, light intensity

Abstract

Production of β-glucan by Agrobacterium sp is influenced by the composition of nutrition in the fermentation media. Molases has been used successfully by others in the fermentation media of S. cerevisiae to increase the yield of -glucan, and similarly, uracil has been used in the fermentation media of Agrobacterium sp to increase the yield of -glucan. Investigations to increase the yield of -glucan by two strains of Agrobacterium sp, i.e. A1.5 (reference) and B4.4 (local strain), have been carried out by addition of various combination of molases and uracil into fermentation media, i.e. 5%(v/v) molase-0,05%(b/v) uracil; 5% molase-0,025% uracil; 10% molase-0,05% uracil; and 10%molase-0,025% uracil. The β-1,3-glucan and β-1,2-glucan fractions were separated by extraction method. Beta-glucan concentration was determined as the glucose monomer using the phenol-sulphate spectrophotometric method at 490 nm. The protein content was determined by a modified Lowry-spectrophotometric method at 750 nm. The results showed that all combination of molases and uracil in the fermentation media of Agrobacterium sp A1.5 and B4.4 strains have increased both the dry-weight yield of β-glucan (crude) and the β- glucan content, with the highest was in a medium containing 10% molases-0,025% uracil combination. In the above medium, the A1.5 strain produced the highest β-glucan (7,5%) with the lowest protein content ( 8,4%) in the β-1,3-glucan fraction, while the β-glucan content in the β-1,2-glucan fraction were all lower than in the control media, while the protein content were all higher than in the control media. Inthe above media, the B4.4 strain produced the highest β-glucan, 7,2% in the β-1,3-glucan fraction, and 13,1% in β-1,2-glucan fraction, while the lowest protein content ( 8,4%) was in the β-1,3-glucan fraction. In conclusion, fermentation media of Agrobacterium sp A1.5 strain or B4.4 strain containing molase and uracil combination have increased both the dry-weight yield of total β-glucan (crude) and the β-glucancontent, while reduced the protein content. There is no clear FTIR spectrum difference between supposedly β-1,2-glucan fraction and β- 1,3-glucan fraction.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Beta glucan, Agrobacterium sp., Molases, Uracil

Abstract

A phenological study with the aim to elucidate flower and fruit development stages in species of Uncaria gambir was conducted in field trial of agricultural faculty of Andalas University-West Sumatra. Observation during flower and fruit organ development was done in eleven inflorescences. Quantitative and descriptive data were collected during one season of flowering time. Phenology of flower and fruit development could be classified in five stages, namely F0 (flower initiation), F1 (small bud scale), F2 (large bud scale), F3 (anthesis, flower opening) and F4 (fruit development). All these events had average completing time in 112 days, and could be detailed as follows: flower initiation stage (F0) took place in 20 days, small scale bud stage (F1) occurred in 27 days, and large scale bud and anthesis stage (F0 and F3) each took place in 5 days, meanwhile fruit development stage (F4=S0) would complete in 53 days. This result should be useful information especially for creating breeding programme in Uncaria gambir species.Key words: Uncaria gambir, phenology, flower development, fruit development.

Abstract

Fluorescent pseudomonass isolated from local plants rishosphere in temanggung controlled lincat disease of tobacco. This report describe phenotypic charactheristics of the bacteria in order to be used as a base for the development of the bacteria as a biological control agent of lincat disease. Phenotypic charactheristics of six isolates of fluorescent Pseudomonass which controlled lincat disease in the field weredetermined in the laboratory of Plant Bacteriology, Faculty of Agriculture, Gadjah Mada University. Plant pathogenicity tests were conducted by hypersensitive reaction into tobacco leaf and inoculation to tobacco plants. Antagonism test between fluorescent Pseudomonass and other candidate of biological control agents were also conducted. The results indicated that the bacteria were rod shape, Gram negative, positive reaction in catalase and oxidase tests. Nitrate reduce to nitrite, arginine was hydrolysed, fluorescent pigment were produced on King’s B medium, levan formation positive and all bacteria denitrifiy. The bacteria used urea, tween 80 and amylum were not hydrolised, poly- -hydroxybutyrate was not accumulated in the cells. Negative reactions were observed for lysine decarboxylation, indol production, VP/MR reaction, and gelatn liquefation. Some compounds could be used as solely carbon sources. All isolates grew on the medium containing 2% NaCl. The best pH for growth was 6-7 and all isolates grew at 20-41C. Negative result were obtained for hypersensitive reaction and pathogenicity tests.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: fluorescent Pseudomonas, phenotypic characteristics, tobacco, lincat disease
