Abstract

Mudiana D, Ariyanti EE (2010) Flower and fruit development of Syzygium pycnanthum Merr. & L.M. Perry. Biodiversitas 12: 124-128. Flower formation is a process of flowering plant in order to produce the next generation. Flower plays a major role in pollination and fertilization as early stage of fruit and seed formation. Syzygium pycnanthum is a member of family Myrtaceae or known as ‘Jambujambuan’ family. The research aim was to observe the development process of flowering and fruiting phase of S. pycnanthum at Purwodadi Botanical Garden. It has been noted that this species has ten (10) stages of flowering and fruit development, namely flower bud initiation, flower bud fully emerge, unfolding calyx, visible corolla, bud starts blooming, early blooming, perfectly blooming, perianths and anthers fall, early fruit structure and ripe fruit. All these stages require 80-89 days.Key words: Syzygium pycnanthum, flower and fruit development.

Abstract

Taurusman AA (2010) Community structure of macrozoobenthic feeding guilds in responses to eutrophication in Jakarta Bay.Biodiversitas 11: 133-138. The group of benthic fauna which feed on the same food sources are classified as a feeding guild. The objective of the present study was to evaluate the distribution and composition of macrozoobenthic feeding guilds along gradient of organic enrichment (trophic states) in Jakarta Bay. The result of the present study was shown that at the hypertrophic stations of the bay dominated by species of surface deposit feeding polychaetes such as, Dodecaceria sp., Cirratulus sp., Capitella sp., and Spionidae. The eutrophic zone of the bay was dominated by suspension feeding bivalves Mactra sp., Chione sp. The offshore area (mesotrophic zone)showed a high diversity of species and feeding guilds compared to other areas. The patterns of feeding guilds in the mesotrophic zone indicated a higher stability of macrozoobenthos community, indicated by the presence of deep-deposit feeder (e.g. Acetes sp.), surface deposit feeders (e.g. Prionospio sp.), suspension feeders (e.g. Chione sp.), and carnivores (e.g. Nephthys sp.) in comparable proportions.The structure of macrozoobenthic feeding guilds in an eutrophic coastal water is positively related to the quantity and quality of organic matters (eutrophic states), and the capability of benthic species in adaptation to such environmental condition.Key words: macrozoobenthos, feeding guild, eutrophication, coastal water, Jakarta Bay.

Abstract

Dewiyanti I (2010) Litter decomposition of Rhizophora stylosa in Sabang-Weh Island, Aceh, Indonesia; evidence from mass loss and nutrients. Biodiversitas 11: 139-144. Mangrove is an essential coastal ecosystem that provides nutrients to estuarine and its surrounding environments through its litter decomposition. This vegetation can be considered as an important ecosystem in food web along the coast. The research was conducted in mangrove forest in Sabang-Weh Island, Aceh. Rhizophora stylosa was dominant species of mangrove in the study area that still remains after tsunami catastrophe in 2004. This study was conducted from February to April 2008, and the purposes were to obtain the decomposition rate of senescent leaves and to measure mass loss, and nutrient contents of decomposing leaves under different inundation regime. Three plots were established in each site. Decomposition of R. stylosa leaves were studied by using litter bag technique. They were made of synthetic nylon which had size 20x30 cm and mesh size was 1x1.25 mm2. Senescent leaves were used because they present major leaves on the forest floor and started to decay. Remaining leaves decreased during experiment period because decomposition process had been taking place in the study area. Time required for decomposing a half of theinitial material (t50) was 67 days and 63 days for site next to the land and site next to the sea, respectively. The decay rate can be expressed by the decay coefficient (K) and the results of K were 0.010 and 0.011 (d-1). The value of carbon (C), nitrogen (N), C: N ratio and phosphorous (P) during decomposition periods were no significant difference in sites but significant difference in time. The C: N ratio of decomposing leaves decreased in both sites. Low C: N ratio in the last of observation indicated that R. stylosa leaves weredecomposed easier at the end of observation than that in the beginning of observation.Key words: Rhizophora stylosa, leaves litter, mass loss, nutrients, Aceh.

Abstract

Abbas B, Renwarin Y, Bintoro MH, Sudarsono, Surahman M, Ehara H (2010) Genetic diversity of sago palm in Indonesia based on chloroplast DNA (cpDNA) markers. Biodiversitas 11: 112-117. Sago palm (Metroxylon sagu Rottb.) was believed capable to accumulate high carbohydrate content in its trunk. The capability of sago palm producing high carbohydrate should be an appropriate criterion for defining alternative crops in anticipating food crisis. The objective of this research was to study genetic diversity of sago palm in Indonesia based on cpDNA markers. Total genome extraction was done following the Qiagen DNA isolation protocols 2003. Single Nucleotide Fragments (SNF) analyses were performed by using ABI Prism GeneScanR 3.7. SNF analyses detected polymorphism revealing eleven alleles and ten haplotypes from total 97 individual samples of sago palm. Specific haplotypes were found in thepopulation from Papua, Sulawesi, and Kalimantan. Therefore, the three islands will be considered as origin of sago palm diversities in Indonesia. The highest haplotype numbers and the highest specific haplotypes were found in the population from Papua suggesting this islands as the centre and the origin of sago palm diversities in Indonesia. The research had however no sufficient data yet to conclude the Papua origin of sago palm. Genetic hierarchies and differentiations of sago palm samples were observed significantly different within populations (P=0.04574), among populations (P=0.04772), and among populations within the island (P=0.03366), but amongislands no significant differentiations were observed (P= 0.63069).Key words: genetic diversity, sago palm, chloroplast DNA, haplotype, Indonesia.

Abstract

Budiharta S (2010) Floristic composition at biodiversity protection area in Lubuk Kakap, District of Ketapang, West Kalimantan. Biodiversitas 11: 151-156. A study on floristic composition has been conducted at biodiversity protection area (Kawasan Perlindungan Plasma Nutfah, KPPN) of PT. Suka Jaya Makmur in Lubuk Kakap, District of Ketapang, West Kalimantan. Two sampling methods were used: Point-Quarter sampling (Quadrant method) of 50 m was applied to class of tree, and 2x2 m2 plot sampling to class of sapling. Of 20 sampling units, 48 species of tree (belong to 27 genera and 13 families) and 94 species of sapling (belong to 54 genera and 28 families) were recorded. Shannon-Wiener diversity index (H’) were 3.54 and 3.49 for tree and sapling respectively, while Pielou evenness index (J’) were 0.91 and 0.77 for tree and sapling respectively. Forest ecosystem in this area can be classified as lowland ever wet tropical rain forest which dominated by dipterocarps species. Species of sapling with the highest importance value index were Shorea laevis, Hopea dryobalanoides and Shorea sandakanensis, while that of tree included Dipterocarpus caudiferus, Shorea laevis and Dryobalanops sp. The floristic composition at family level showed comparatively similar pattern with that at other sites inKalimantan although composition at species level was different.Key words: biodiversity protection area, dipterocarpaceae, floristic composition, High Conservation Value Forest (HCVF), production landscape

Abstract

Djuuna IAF, Abbott LK, Van Niel K (2010) Predicting infectivity of Arbuscular Mycorrhizal fungi from soil variables using Generalized Additive Models and Generalized Linear Models. Biodiversitas 11: 145-150. The objective of this study was to predict the infectivity of arbuscular mycorrhizal fungi (AM fungi), from field soil based on soil properties and land use history using generalized additive models (GAMs) and generalized linear models (GLMs). A total of 291 soil samples from a farm in Western Australia near Wickepin were collected and used in this study. Nine soil properties, including elevation, pH, EC, total C, total N, P, K, microbial biomass carbon, and soil texture, and land use history of the farm were used as independent variables, while the percentage of root length colonized (%RLC)was used as the dependent variable. GAMs parameterized for the percent of root length colonized suggested skewed quadratic responses to soil pH and microbial biomass carbon; cubic responses to elevation and soil K; and linear responses to soil P, EC and total C. The strength of the relationship between percent root length colonized by AM fungi and environmental variables showed that only elevation, total C and microbial biomass carbon had strong relationships. In general, GAMs and GLMs models confirmed the strong relationship between infectivity of AM fungi (assessed in a glasshouse bioassay for soil collected in summer prior to the first rain of the season) and soil properties.Key words: AM Fungi, GAM, GLM, land use.

Abstract

Suhartono (2010) Examination of uropathogenic Escherichia coli strains conferring large plasmids. Biodiversitas 11: 59-64. Of major uropathogens, Escherichia coli has been widely known as a main pathogen of UTIs globally and has considerable medical and financial consequences. A strain of UPEC, namely E. coli ST131, confers a large plasmid encoding cephalosporinases (class C β-lactamase) or AmpC that may be disseminated through horizontal transfer among bacterial populations. Therefore, it is worth examining such large plasmids by isolating, purifying, and digesting the plasmid with restriction enzymes. The examination of the large plasmids was conducted by isolating plasmid DNA visualized by agarose gel electrophoresis as well as by PFGE. The relationship of plasmids among isolates was carried out by HpaI restriction enzyme digestion. Of 36 isolates of E. coli ST 131, eight isolates possessed large plasmids, namely isolates 3, 9, 10, 12, 17, 18, 26 and 30 with the largest molecular size confirmed by agarose gel electrophoresis and PFGE was ~42kb and ~118kb respectively. Restriction enzyme analysis revealed that isolates 9, 10, 12, 17 and 18 have the common restrictionpatterns and those isolates might be closely related.Key words: large plasmids, uropathogenic E. coli, electrophoresis, RE, PFGE

Abstract

The aims of the present research are two folds: to know the phenotypic diversity and to reconstruct the cross-breeding pattern of local cattle in Banyuwangi. Based on three sampling areas, it was found that there were 32 phenotypic cattle (10 in the sub districts of Rogojampi, 16 in Tegaldlimo and 6 in Glagah areas). The phenotypic varieties were caused by two factors, namely the flow of genetic intervention of the other local cattle (Bali, Ongole, and Brahman cattle) and the artificial insemination program using the semen of Limousine, Simmental, Aberdeen Angus and Santa Gertrudis cattle. © 2010 Biodiversitas, Journal of Biological DiversityKey words: flow of genetic intervention, local cattle, phenotypic variation

Abstract

Perwitasari-Farajallah D, Kyes RC, Iskandar E (2010) Microsatellite DNA polymorphisms for colony management of long-tailed macaques (Macaca fascicularis) population on the Tinjil Island. Biodiversitas 11: 55-58. Polymorphic genetic markers are the basic requirement for studies on population and conservation genetics of non-human primates. In this paper, we screened microsatellites for their polymorphism and gene typing of DNA samples from blood of wild long-tailed macaques (Macaca fascicularis) from Tinjil Island population. Among the three primer sets tested, two are polymorphic. They were D1S548 and D3S1768. Average observed heterozygosity (Ĥ) within populations ranged between 0.264-0.555. D1S1768 locus was highly polymorphic and 24 alleles were detected among two loci. Estimation of genetic variability for the Tinjil population (Ĥ) was 0.485. The results obtained provide furtherinsight into the long-term viability of the population and help in creating genetic management of both captive and natural habitat breeding colonies of primates.Key words: microsatellite, variations, social groups, long-tailed macaques, Macaca fascicularis
