Abstract

Hernawati H, Wiyono S, Santoso S (2011) Leaf endophytic fungi of chili (Capsicum annuum) and their role in the protection against Aphis gossypii (Homoptera: Aphididae). Biodiversitas 12: 187-191. The objectives of the research were to study the diversity of leaf endophytic fungi of chili, and investigate its potency in protecting host plants against Aphis gossypii Glov. Endophytic fungi were isolated from chili leaves with two categories: aphid infested plants and aphid-free plants, collected from farmer’s field in Bogor, West Java. Abundance of each fungal species from leave samples was determined by calculating frequency of isolation. The isolated fungi were tested on population growth of A. gossypii. The fungal isolates showed suppressing effect in population growth test, was further tested on biology attributes i.e. life cycle, fecundity and body length. Five species of leaf endophytic fungi of chili were found i.e.Aspergillus flavus, Nigrospora sp., Coniothyrium sp., and SH1 (sterile hypha 1), SH2 (sterile hypha 2). Even though the number of endophytic fungi species in aphid-free and aphid-infested plant was same, the abundance of each species was different. Nigrospora sp., sterile hyphae 1 and sterile hyphae 2 was more abundant in aphid-free plants, but there was no difference in dominance of Aspergillus flavus and Coniothyrium sp. Nigrospora sp., SH1 and SH2 treatment reduced significantly fecundity of A. gossypii. Only SH2 treatment significantly prolonged life cycle and suppress body length, therefore the fungus had the strongest suppressing effect on populationgrowth among fungi tested. The abundance and dominance of endophytic fungal species has relation with the infestation of A. gossypii in the field.

Abstract

Djuuna IAF, Masora M, Puradyatmika P (2011) Soil microorganisms numbers in the tailing deposition ModADA areas of Freeport Indonesia, Timika, Papua. Biodiversitas 12: 198-203. The objective of this study was to examine the number and distribution of bacteria, fungi and actinomycetes in the inactive tailing deposition areas of Freeport Indonesia Mining and Gold Company, Timika. One hundred ninety eight composite samples (0-20 cm) were taken from four location of inactive tailing ModADA (Modification Aijkwa Deposition Areas) namely double levee-bottom (fine texture); double levee-middle (medium texture); double levee-top (coarse texture);Mile 21 and transmigration areas of I to V. The conventional method of dilution and Plate Count Agar were used to examine the population of soil bacteria, fungi and actinomycetes. pH and moisture content were also analyzed. The numbers of bacteria in the tailing deposition areas are in the range from 3.48x105 CFU/g soil to 102.83x105 CFU/g soil, soil fungi from 1.51x105 CFU/g soil to 106.61x105 CFU/g soil and actinomycetes range from 0.32x104 CFU/g soil to 113.74x104 CFU/g soil. While in some transmigration areas, the number of soil bacteria, fungi and actinomycetes were lower than in the tailing areas. The number of soil bacteria and fungi were higher than actinomycetes. However, the coefficient of variation of actinomycetes (107%) was higher than soil fungi (89%) andbacteria (68%). Tailing deposition areas are considered as a good habitat for soil microorganisms. Overall, the number of soil organism in the tailings areas are considered medium to high, however to understand their functioning in each location under different land use system, more research are needed to evaluate their roles especially in the decomposition of soil organic matter.

Abstract

Mutaqien Z, Zuhri M (2011) Establishing a long-term permanent plot in remnant forest of Cibodas Botanic Garden, West Java. Biodiversitas 12: 218-224. Cibodas Botanic Garden (CBG) has unique characters; almost 10% of which is forested area adjacent to the natural forest of Mt. Gede Pangrango National Park. The area is a transition between natural forest and artificial habitat which mostly consists of exotic plant species. The permanent plot in CBG was established in 2007-2009. Two hundred and eighty four units of 10x10 square meters sub-plot were established in four locations, i.e. Wornojiwo, Kompos, Jalan Akar, and Lumut forest. Vegetation analyses were conducted for trees, saplings, shrubs, and herb species. The inventory found 137 species plants consisting of 74 tree speciesdominated by Villebrunea rubescens (Bl.) Bl. and Ostodes paniculata Bl., 30 shrub species dominated by Strobilanthes hamiltoniana (Steud.), 24 herb species dominated by Cyrtandra picta Bl., 6 fern species mainly consisted of Diplazium pallidum Moore, and 3 climber species dominated by Calamus reinwardtii Mart. In comparison with the natural forest of Mt. Gede Pangrango National Park, the CBG permanent plot showed a good representative of the vegetation of lower montane forest. A regular monitoring during the successive years is needed to maintain diversity, monitor forest dynamics and anticipate the spread of invasive plant from CBG.

Abstract

Sutomo, Faradila D, Putri LSE (2011) Species composition and interspecific association of plants in primary succession of Mount Merapi, Indonesia. Biodiversitas 12: 212-217. Primary succession refers to the establishment of plant species and subsequent changes in composition following major disturbance such as volcanic activity. The study of succession may assist in recognizing the possible effects of species interactions (i.e. facilitation or inhibition). The barren landscapes created by volcanic disturbance on Mount Merapi, Java, Indonesia, provide excellent opportunities to study primary succession. Fifty-six species belonging to 26 families were recorded in the five nuées ardentes deposits. The highest number of species belonged to the Asteraceae, then Poaceae, followed by Fabaceae andRubiaceae. In Mount Merapi primary succession, the ecosystem may be developing with time as indicated by the increase in the number of species associations. The number of positive associations was generally higher than the number of negative associations, except in the 2001 deposit where it was equal. Native and alien invasive species had different patterns of interspecific associations. This research demonstrates that in primary succession sites on Mount Merapi, positive interspecific association increased as time progressed, which may support the view that facilitation is more prominent in a severely disturbed habitat as compared to competition.

Abstract

Praptosuwiryo TNg, Pribadi DO, Puspitaningtyas DM, Hartini S (2011) Inventorying the tree fern Genus Cibotium of Sumatra: Ecology, population size and distribution in North Sumatra. Biodiversitas 12: 204-211. Cibotium is one tree fern belongs to the family Cibotiaceae which is easily differentiated from the other genus by the long slender golden yellowish-brown smooth hairs covered its rhizome and basal stipe with marginal sori at the ends of veins protected by two indusia forming a small cup round the receptacle of the sorus. It has been recognized as material for both traditional and modern medicines in China, Europe, Japan and Southeast Asia. Population of Cibotium species in several countries has decreased rapidly because of over exploitation and there is no artificial cultivation until now. The aims of this study were: (i) To re-inventory the species of Cibotiun in North Sumatra, (ii) to record the ecology and distribution of each species, and (iii) to assess the population size of each species. Field study was carried out by using random search with belt transect. Two species were recorded, namely C. arachnoideum dan C. barometz. The geographical distribution of the two species in North Sumatra is presented. Cibotium is commonly growing terrestrially on opened or rather opened areas in secondary forest and primary forest at hills or lower mountains with a relatively high humidity at 30-90º slopes. C. arachnoideum has a strict distribution and only found at 1740-1770 m a.s.l. in primary forest, whereas C. barometz has a broad distribution in secondary forest at elevation range from 650-1200 m.

Abstract

Yulia ND, Budiharta S, Yulistyarini T (2011) Analysis of epiphytic orchid diversity and its host tree at three gradient of altitudes in Mount Lawu, Java. Biodiversitas 12: 225-228. The aim of this study was to observe epiphytic orchid diversity and their host trees at three different altitudes (1796, 1922 and 2041 m asl.) at southern part of Mount Lawu, District of Magetan, East Java. Line transect of 10 x 100 m was set up and then divided into ten plots (as replicates) of 10 x 10 m. At each plot, species name and number of individual of epiphytic orchids, and species name, number of individual and diameter at breast height (dbh) of host trees were recorded. The result showed that there were 19 species of epiphytic orchid recorded at the study sites. There were significantly different among gradient altitude in number of epiphytic orchid species (F = 3.7; df = (2, 27); P < 0.05). The highest number of species of epiphytic orchid was recorded at the altitude of 1922 m asl. (6.6 species/100 m2) while the highest number of individual was recorded at the altitude of 1796 m asl. (1337.7 individuals/100 m2). The study site at altitude of 1922 m asl. was recognized as the denser and richer in species of host trees (2.3 species/100 m2 and 3.5 individuals/100 m2 respectively). However, the highest basal area of host tree was recorded at the altitude of 2041 m asl. (4558 cm2/100 m2).

Abstract

Pribadi T, Raffiudin R, Harahap IS (2011) Termites community as environmental bioindicators in highlands: a case study in eastern slopes of Mount Slamet, Central Java. Biodiversitas 12: 235-240. Termites ecological behavior is much affected by land use change and disturbance level. Their variation in diversity can be used as bioindicator of environmental quality. However, termite community response to land use changes and habitat disturbance in highland ecosystems remains poorly understood. This study was conducted to investigate the response of termite community to land use intensification and to explore their role as environmental bioindicator in Mount Slamet. A standard survey protocol was used to collect termites in five land use types of various disturbance levels, i.e. protected forest, recreation forest, production forest, agroforestry, and urban area. It was found two termite families i.e. Rhinotermitidae andTermitidae with seven species, i.e. Schedorhinotermes javanicus, Procapritermes sp, Pericapritermes semarangi, Macrotermes gilvus, Microtermes insperatus, Nasutitermes javanicus, and N. matangensis. Termite species’ richness and evenness, Shannon-Wiener index, relative abundance, and biomass of termite were declined along with the land use types and disturbance level from protected forest to urban area. Habitat disturbance was the main declining factor of termite diversity. Termite composition changed along with the land usedisturbance level. Soil feeding termites were sensitive to the disturbance – they were not found in urban area. Hence, their presence or absence can be used as environmental bioindicator to detect habitat disturbance.
