Abstract

Widawati S. (2011). Diversity and phosphate solubilization by bacteria isolated from Laki Island coastal ecosystem. Biodiversitas 12: 1721. Soil, water, sand, and plant rhizosphere samples collected from coastal ecosystem of Laki Island, Jakarta, Indonesia were screened for phosphate solubilizing bacteria (PSB). While the population was dependent on the cultivation media and the sample type, the highest bacterial population was observed in the rhizosphere of Ipomoea aquatica. The PSB strains isolated from the sample registered 18.59 g-1 L-1. 18.31 g-1 L-1, and 5.68 g-1 L-1 of calcium phosphate (Ca-P), Al-P and rock phosphate solubilization after 7-days. Phosphate solubilizing capacity was the highest in the Ca-P medium. Two strains, 13 and 14, registered highest phosphomonoesterase activities (2.01 µgNP.g-1.h-1 and 1.85NP µg.g-1.h-1) were identified as Serratia marcescens, and Pseudomonas fluorescens, respectively. Both strains were isolated from the crops of Amaranthus hybridus and I. aquatica, respectively, which are commonly observed in coastal ecosystems. The presence of phosphate solubilizing microorganisms and their ability to solubilize various types of phosphate species are indicative of the important role of both species of bacteria in the biogeochemical cycle of phosphorus and the plant growth in coastal ecosystems.

Abstract

Amarantini C, Sembiring L, Kushadiwijaya H, Asmara W T . It was also found that the isolates which belong to S. typhi species formed several different centers of diversity within the 16S rRNA gene tree. Each clade consisted of the strains from different geographical places in the District. Thus, to conclude the inquiry, there was evident inter-geographical spread of the strains and it tended to spread further into more remote areas in the District.

Kurniawan A, Wibawa IPAH, Adjie B (2011). Species diversity of Amorphophallus (Araceae) in Bali and Lombok with attention to genetic study in A. paeoniifolius (Dennst.) Nicolson. Biodiversitas 12: 7-11. Amorphophallus belongs to Araceae family that consists of more than 170 species worldwide and distributed predominantly in tropical countries, especially in Asia and Africa. The study of Amorphophallus in Bali and Lombok Islands had been conducted to reveal its diversity. Genetic study was also conducted among Amorphophallus paeoniifolius species to recognize the variation within the species. The fieldworks showed three species Amorphophallus distributed in Bali, notably A. muelleri Blume, A. paeoniifolius (Dennst.) Nicolson, A. variabilis Blume and two species in Lombok, notably A. muelleri and A. paeoniifolius. Var. hortensis and var. sylvestris were two varieties of A. paeoniifolius that commonly found either in Bali or in Lombok. Genetic study on A. paeoniifolius indicated that there was no genetic variation in cpDNA region of trnL-F IGS within the species.

Abstract

Hadiwiyono, Widada J, Subandiyah S, Fegan F (2011). Pulsed Field Gel Electrophoresis (PFGE): a DNA finger printing technique to study the genetic diversity of blood disease bacterium of banana. iodiversitas 12: 12-16. Blood disease bacterium (BDB) is the most important pathogen of bananas in Indonesia. In some field, the disease incidence reaches over 80%. Epidemiologically, the disease is similar to Moko disease in South America and Bugtok disease in the Philippines caused by Ralstonia solanacearum race 2. However, BDB is different in phenotype and genotype from the two diseases. Previously BDB was limited in South Sulawesi since 1920s – 1980s and recently was reported in 27 of 30 provinces in Indonesia. Pulsed-Field Gel Electrophoresis (PEGE) is a genomic DNA fingerprinting method, which employs rare cutting restriction endonucleases to digest genome prior to electrophoresis using specialized condition to separate of large DNA fragments. The results showed that PFGE analysis was a discriminative tool to study the genetic diversity of BDB. Based on the PFGE analysis, BDB isolates obtained from different localities in Yogyakarta and Central Java were quit diverse.

Abstract

Yulia ND, Budiharta S (2011). Epiphytic orchids and host trees diversity at Gunung Manyutan Forest Reserve, Wilis Mountain, Ponorogo, East Java. Biodiversitas 12: 22-27. Natural forests in Wilis Mountain have been destroyed by forest fires, landslides and illegal logging. As a consequence, biological diversity in this area is threatened by local extinctions, particularly of orchid species. This study was aimed to explore, document and analyze the diversity of epiphytic orchids at Gunung Manyutan Forest Reserve, a natural forest area in Wilis Mountain. Purposive sampling on 1 hectare (50 x 200 m2) eight subplots (25 x 50 m2) All data on orchid species were recorded including its number, host trees and zone of the host tree where the orchid attached. The results showed that there were 29 epiphytic orchid species recorded. Flickingeria angulata was the most abundant species (Relative Abundance of orchids/ %Fo = 38.74), continued by Appendicula sp. (%Fo = 10.91) and Eria hyacinthoides (%Fo=6.57). The three most important host trees were Pinus merkusii, Schima wallichii and Engelhardia spicata. Zone 3 (bottom part of the branches) was revealed as the most favorable part at the host tree (281 individuals), while Zone 1 (bottom part of the main stem) was the least preferable one.

Abstract

Lestari DA, Santoso W (2011) Inventory and habitat study of orchids species in Lamedai Nature Reserve, Kolaka, Southeast Sulawesi. Biodiversitas 12: 28-33. Orchid is one of the ornamental plants which have been high commercial value. Therefore, orchid often has been over exploitation. Finally, some of orchid species are becoming threatened or even endangered. Purwodadi Botanical Garden as an institute of ex-situ conservation play role with it. The aim of this research is to inventory orchid’s species in Lamedai Nature Reserve, Kolaka, Southeast Sulawesi by explorative method. Observation for habitat study was focused on some ecological factors supported to orchids growth like host tree, zone growth on host tree, abundance of sunlight, thickness of substrate (moss), orchid species and number of individual species. The result showed that there were 27 orchids species, consist of, 25 species (16 genera) epiphytic orchid and 2 species terrestrial orchid such as Eulophia keithii var. celebica and Goodyera rubicunda (Blume) Lindl. The host preference for theepiphytic orchid is the group of Myrtaceae family like Syzygium sp., Metrosideros vera Niederen and Metrosideros sp. They mostly grow on the main stem of the tree zone 1 on thick substrate (moss) and get a little abundance of sunlight (calm).

Abstract

Riyanto A (2011) Herpetofaunal community structure and habitat associations in Gunung Ciremai National Park, West Java, Indonesia. Biodiversitas 12: 38-44. Community structure and habitat associations of amphibians and reptiles on both rainy and dry seasons of six habitat types of three sites in Gunung Ciremai National Park, West Java were investigated in March and October 2008. The data of herpetofauna was obtained by opportunistic searches. Herpetofaunal diversity for each habitat was determined by using Shannon Wienerindex, the species abundance per unit area was calculated by using Margalef’s index, and the homogeneity of distribution of species in relation to other species in a sampled per unit area was evaluated using Evenness index. The similarity in herpetofauna communities among habitat types was determined using Sorensen’s coefficient, meanwhile the Jaccard’s index was used to estimate similarities in habitat utilization. Thus, both community similarities and habitat utilization displayed in cluster dendrogram. A total of 46 amphibian and reptile taxa were recorded, comprising 16 anurans, 22 lizards and 8 snakes. Of the total taxa, four anurans are endemic and unusual specimens probably new in sciences referred to the genus Cyrtodactylus and Eutropis. There were differed in sequential of biological indices among habitat types but not much different in their values. The result of cluster analysis showed different patterns on the community similarity among habitat type and habitat utilization during rainy and dry seasons.Key words: community, habitat utilization, amphibians, reptiles, Gunung Ciremai, Indonesia

Abstract

Setyobudi E, Soeparno, Helmiati S (2011) Infection of Anisakis sp. larvae in some marine fishes from the southern coast of Kulon Progo, Yogyakarta. Biodiversitas 12: 34-37. The prevalence, intensity and distribution of Anisakis sp. larvae which infected some fishes at the southern coast of Kulon Progo District were investigated. Totally 95 fish specimens were collected during December 2007. Results of the present study indicated that the Anisakis sp. larvae infected various fish species i.e: Trichiurus lepturus, Parupeneus sp., Lutjanusmalabaricus, Terapon jarbua and Caesio sp. Prevalence and mean intensity of infection showed the differences between fish species. The highest mean intensity of infection was found in L. malabaricus (7.71 larvae/infected host) and T. Lepturus (3.18 larvae/infected host), while the lowest intensity of infection was found in Parupeneus sp., T. jarbua and Caesio sp. (1 larvae/infected host). Infected host organs were body cavities (peritoneum), digestive tract, gonads, and liver. Presence of this parasite may be harmful for consumer; however it can be used for several ecological studies as biological tags.Key words: Anisakis sp., infection, southern coast of Kulon Progo District.

Abstract

Wijayanto N (2011) Species identification and selection to develop agroforestry at Lake Toba Catchment Area (LTCA). Biodiversitas 12: 52-58. In order to improve land productivity surrounding the LTCA, the existing ITTO project tries to establish agroforestry system. The system will be designed to meet consideration of both sides. on one side is to generate the people awareness of the forest and land rehabilitation, and on the other side is to support the poverty reduction. The aims of this research are: species identification and selection to develop agroforestry at LTCA. Data collecting was carried out with: interview, group discussion, field observation, divining manual study, and PRA. The diversity of the available crop kind shows the number of choices to be developed by the farmer. The farmers generally have the economic objective to develop agroforestry, including increase in net income, risk reduction, increase in environmental service, and the wealth and savings accumulation. Various types of agricultural crops, plantations and forest trees were found in LTCA. They can be the basis for building a wide variety of agroforestry systems.Key words: catchment area, agroforestry system, sequential, integrated.
