El-Nagerabi SAF, Elshafie AE, AlKhanjari SS. 2013. Endophytic fungi associated with Ziziphus species from mountainous area ofÂ Oman and new records. Biodiversitas 14: 10-16. Ziziphus species of the family Rhamnaceae grow extensively in arid and semi-aridÂ regions. It is possible that the endophytic fungi associated with this plant might enhance the host resistance to the environmentalÂ impacts. The endophytic fungal population inhabiting the healthy leaves of Z. spina-christi and Z. hajanensis plants were determinedÂ from April 2008 to October 2011. The endophytic fungal communities varied between the two species, and 45 fungal species, 18 sterileÂ mycelia and 12 yeasts were isolated from Z. spina-christi, whereas 35 fungi, 11 sterile mycelia and 5 yeasts were recovered from Z.Â hajanensis indicating tissue and species-specificity and without any seasonal variation among the endophytes. These endophytes areÂ new to Ziziphus plants and 45 species are new to the mycoflora of Oman, whereas 27 species are new to Arabian Peninsula. The genusÂ Alternaria was the most prevalent (19-81%)Â followed by Aspergillus (19-78%),Â Rhizopus stolonifer (78%),Â Mycelia sterilia (69%),Â yeasts (47%),Â Cladosporium (11-56%),Â Drechslera (14-53%),Â Curvularia (8-50%),Â Fusarium (6-33%),Â Ulocladium (41-31%),Â Penicillium (3-22%),Â Alysidium resinae (11%),Â Trichocladium (6-11%),Â Anguillospora longissima, Bactrodesmium rahmii, Catenularia (8%),Â Helminthosporium sorghi (7%),Â Dendryphiella infuscans (6%),Â Hansfordia biophila (3-6%), Arthrinium, Dissophora, and Phoma sorghina (3%). The recovery of many fungal isolates, morphologically various sterile mycelia and yeasts suggests the high biodiversity of the endophytes invading these plants with strong evidence for future isolation of numerous fungal species through adopting more advanced molecular and DNA identification methods.

The objective of our study was to determine if soil physical indicators could be related toÂ the influence of the individual trees in stands of mixed species growing on steep slopes in the Hyrcanian forests of Iran. Research wasÂ conducted in a forest dominated by beech 2Â cross section. The result of this research showed that bulk density was significantly greater under beech than under hornbeam.Â This character tends to be less in 0-15cm depth than in 15-30cm and 30-45cm depths. Variable amounts of this character were foundÂ among diameter classes of beech and hornbeam also. Silt and clay were significantly greater under hornbeam than under beech.Â Moisture was significantly higher under beech than under hornbeam, whereas soil depths and diameter classes did not show anyÂ significant difference. Current research has shown that the influence of individual trees with different diameter classes can be detected inÂ forest floors and upper minerals soil layers even under mixed stands in steepy sloping landscapes. This subject should be considered inÂ natural forests management.

Wiryono, Siahaan AB. 2013. Species composition of understory vegetation in coal mined land in Central Bengkulu, Indonesia.Â Biodiversitas 14: 31-36. Coal strip mining in forest area has destroyed forest ecosystem and created barren land. Reclamation of minedÂ land is done by revegetating the land. In addition to planted species, pioneer species usually grow naturally in mined land. TheÂ objectives of this study were to know the species composition of understory vegetation growing naturally in coal mined land plantedÂ with Gmelina arborea in Central Bengkulu, Indonesia, and to compare that composition with that of unreclaimed coal mined land and ofÂ natural forests. Data were collected by sampling understory vegetation in study site. Each plant was identified, harvested and oven-driedÂ to find the biomass. Results showed that the reclaimed mined land had 16 understory species from 6 families, and the abandoned minedÂ land had 10 species from 3 families, lower than that of natural forests, which were 92 and 112. The three most important species wereÂ Scleria sumatrensis Retz, Eragrostis chariis (Schult.) Hitchc and Paspalum conjugatum Berg. The species composition of understoryÂ vegetation in reclaimed mined land had high similarity with that of abandoned mined land but was totally different from that of naturalÂ forests.

Biodiversitas 14: 43-53. The increasing rates ofÂ coral mortality associated with the rise in stress factors and the lack of adequate recovery worldwide have urged recent calls for actionsÂ by the scientific, conservation, and reef management communities. This work reviews the current trends in coral transplantation.Â Transplantation of coral colonies or fragments, whether from aqua-, mariculture or harvesting from a healthy colony, has been the mostÂ frequently recommended action for increasing coral abundance on damaged or degraded reefs and for conserving listed or â€œat-riskâ€Â species. Phytoplanktons are important for providing transplanted corals with complex organic compounds through photosynthesis.Â Artificial surfaces like concrete blocks, wrecks or other purpose-designed structures can be introduced for larval settlement. NewÂ surfaces can also be created through electrolysis. Molecular biological tools can be used to select sites for rehabilitation by asexualÂ recruits. Surface chemistry and possible inputs of toxic leachate from artificial substrates are considered as important factors affectingÂ natural recruitment. Transplants should be carefully maintained, revisited and reattached at least weekly in the first month and at leastÂ fortnightly in the next three months. Studies on survivorship and the reproductive ability of transplanted coral fragments are importantÂ for coral reef restoration. A coral nursery may be considered as a pool for local species that supplies reef-managers with unlimited coralÂ colonies for sustainable management. Transplanting corals for making artificial reefs can be useful for increasing biodiversity, providingÂ tourist diving, fishing and surfing; creating new artisanal and commercial fishing opportunities, colonizing structures by fishes andÂ invertebrates,Â aving large corals during the construction of a Liquified Natural Gas Plant.

Fungi play an important role in leaf litter decomposition due to their abilityÂ to break down the lignocelluloses matrix, which other organisms are unable to digest. Diversity of bamboo leaf litter fungi from fallenÂ leaves and undergoing active decomposition leaves in different season and different depth was carried out in 2009-10. Twenty fourÂ samples were collected from Bambusetum of Rain Forest Research Institute (RFRI), Â Northeast India. The moist chamber, directÂ isolation and dilution plate methods were used to assess the diversity of fungal species. Fungi were cultivated on 3% malt extract agarÂ and half strength potato dextrose agar. The litter was divided into freshly fallen senescentÂ leaves (grade 1) and leaves alreadyÂ undergoing active decomposition (grade 2). Moist chamber incubation of the litter revealed 45 fungal taxa belonging to 22 genera.Â fungal taxa were found on grade I and 39 fungal taxa found on grade II litter. Although 24 fungal taxa were common to both grades,Â Differences were observed in percentage occurrence of fugal species between the two grades of litter. Periodic surveys were carried outÂ to collect macrofungi. Young and matured carpophores of 16 macro fungi species were collected in different seasons. Out of theseÂ macrofungi, 3 species belongs to family Entolomataceae and Agaricacea, two species belongs to Tricholomataceae and Geoglossaceae oneÂ species belongs to each family Dacrymycetaceae, Pluteaceae, Coprinaceae, Marasmiaceae Lycoperdaceae and Phallaceae. The bambooÂ leaf-litter was selected for the present syudy because of the dominance and great economic value of bamboo vegetation in North-east India.

Published: July 2014

ABSTRACT: The strain SRL8, which could decolorize the azo dye disperse orange S‐RL (S‐RL), was first isolated from sludge and identified as Acinetobacter sp. through physiobiochemical identification and 16S rRNA gene sequences. The effects of temperature, pH, dye concentration, O2, and glucose concentration on S‐RL decolorization by the strain SRL8 were studied. The optimal conditions were 30 °C, pH 7.0, 4g·L−1 of inoculation (wet cells), and microaerophilic incubation. The decolorization percentage for S‐RL by the strain SRL8 could reach 90.2% under optimal conditions. The strain SRL8 was highly tolerant to the azo dye SRL up to 300 mg·L−1 and it had a broad decolorizing spectrum. According to the Monod equation, kinetic parameters of decolorization by SRL8 were calculated. The vmax and Km were 5.57 × 10−3 h−1 and 14.53 mg·L−1, respectively.

Isoscalar giant monopole resonance for drip-line and super heavy nuclei in the framework of relativistic mean field formalism with scaling calculation
Authors: Biswal Subrata , Patra Suresh 
Published: July 2014

AbstractWe study the isoscalar giant monopole resonance for drip-lines and super heavy nuclei in the framework of relativistic mean field theory with a scaling approach. The well known extended Thomas-Fermi approximation in the nonlinear σ-ω model is used to estimate the giant monopole excitation energy for some selected light spherical nuclei starting from the region of proton to neutron drip-lines. The application is extended to the super heavy region for Z=114 and 120, which are predicted by several models as the next proton magic numbers beyond Z=82. We compared the excitation energy obtained by four successful force parameters NL1, NL3, NL3*, and FSUGold. The monopole energy decreases toward the proton and neutron drip-lines in an isotopic chain for lighter mass nuclei, in contrast to a monotonic decrease for super heavy isotopes. The maximum and minimum monopole excitation energies are obtained for nuclei with minimum and maximum isospin in an isotopic chain, respectively.
