Abstract

Rindyastuti R, Rachmawati D, Sancayaningsih RP, Yulistyarini T. 2018. Ecophysiological and growth characters of ten woody plant species in determining their carbon sequestration. Biodiversitas 19: 660-669. Tree planting and ecosystem restoration is one of mitigation program of global climate change scheme to reduce CO2 in the atmosphere by sequestering carbon. Carbon storage in the living plant varies among species due to ecophysiological and growth characters of their photosynthesis. Ecophysiological properties of tropical plant species related to carbon sequestration was lack of investigation. The study in this area will be the significant knowledge contribution to C-sink project especially species-level management which has been agreed globally and nationally. The objectives of this research were to study the ecophysiological and growth factors affecting carbon sequestration and to select plant species with high carbon sequestration using 16 months-old-seedling of ten woody plant species. Biomass, carbon storage, the whole plant photosynthetic capacity, total chlorophyll content, stomatal index, and Leaf Area Index (LAI) were significantly different among species. The LAI, total chlorophyll content, whole plant photosynthetic capacity, stem height and stem diameter were positively correlated to biomass and carbon storage. Multivariate correlation test (P>0.05) revealed that the total of chlorophyll content was the ecophysiological factor most contributes to carbon sequestration. The total of chlorophyll content correlates to the stem height, while the whole plant photosynthesis correlates to leaf area in determining plant carbon sequestration. Moreover, two mangrove species, H. littoralis and B. asiatica have the highest carbon sequestration among species studied. For priority in tree planting program in dry lowland habitats, the local species, i.e., S. cumini and D. discolor were more recommended than any others species observed in this study.

Abstract

Lahjie AM, Lepong A, Simarangkir BDAS, Kristiningrum R, Ruslim Y. 2018. Financial analysis of dipterocarp log production and rubber production in the forest and land rehabilitation program of Sekolaq Muliaq, West Kutai District, Indonesia. Biodiversitas 19: 757-766. The Dayak community of East Kalimantan in the last decade has begun to develop production systems that integrate forest timber tree species into plantation commodity enterprises. They have become aware that the natural forest species of their surroundings such as Meranti (Shorea sp.) and Kapur (Dryobalanops aromatica) are often easier to exploit economically, and represent potentially cheaper investments, than are introduced plantation crops such as rubber (Hevea brasiliensis). This is because the price of rubber latex has decreased over the years and has ceased to give a financial return commensurate with the investment required to develop rubber as a monocrop. The research described in this paper aimed to evaluate the viability of a dipterocarp forest/rubber plantation system cultivated by people in the West Kutai District of East Kalimantan. The viability of the system was evaluated by (i) measuring its production of dipterocarp logs and natural rubber; (ii) determining the diameter distribution of its dipterocarp trees and (iii) assessing the financial feasibility of the dipterocarp/rubber system using the theories of increment production and basal area applied to the determination of Pay Back Period, Net Present Value (NPV), Net Benefit Cost (B/C) ratio and Internal Rate of Return (IRR). The research areas on which the evaluation was performed consisted of (1) a mixed population of Shorea spp. (Meranti) and rubber (Hevea brasiliensis) and (2) a mixed population of Dryobalanops aromatica (Kapur) and rubber. The growth analysis of Shorea spp. combined with rubber as well as D. aromatica combined with rubber at the planting distance of 5m x 5m showed that the maximum cycle was reached at the age of 40 years. Whereas the rubber trees in monoculture cultivation reached their maximum cycle at the age of 17 years. The optimum increment of MAI and CAI of Shorea spp. combined with rubber reached 3.61 m3 ha-1 year-1 and 3.62 m3 ha-1 year-1 respectively. The maximum increment of MAI and CAI of Dryobalanops aromatica combined with rubber reached 3.09 m3 ha-1 year-1 and 3 m3 ha-1 year-1 respectively.

Abstract

Karyati, Ipor IB, Jusoh I, Wasli ME. 2018. Tree stand floristic dynamics in secondary forests of different ages in Sarawak, Malaysia. Biodiversitas 19: 767-773. Succession is a series sequential processes of the development of floristic community which involves changes in community structure, species composition and diversity over time. The information on tree stand floristic dynamics of various stages of succession in secondary forests in Malaysia is currently lacking. This study was conducted to determine tree stand structure, floristic composition, and species diversity in various stages of secondary forest development in the study areas. A total of 997, 1,842, and 834 tree stems with diameter at breast height (DBH) of > 5 cm were recorded in one-hectare-plots of 5, 10, and 20 year old secondary forests, respectively. The ten most common species in 5 and 10 year old of secondary forests consisted mostly of light demanding species. In the 20 year old secondary forest, these species did not exist. Macaranga gigantea was the most dominant tree species in the 5 and 10 year old secondary forests in terms of basal area and volume per hectare. The most common species, based on density, basal area, volume, and Importance Value Index (IVi), in the 20 year old secondary forest was Adinandra dumosa. The diversity and richness indices of the 10 year old secondary forest were the highest among all study sites.

Abstract

Hervani D, Efendi D, Suhartanto MR, Purwoko BS. 2018. The preservation of somatic embryos of papaya derived from papaya lateral shoots after being stored in cryopreservation to maintain plant genetic information in the future. Biodiversitas 19: 724-729. Germplasm storage of papaya is very important because this plant easily adapts to genetic changes due to environmental conditions and open system pollination, so it is necessary to retain the current genetics resources in order to conserve the genetic information. The storage of the vegetative part of the plant with cryopreservation is expected to retain the plant's genetic information in the future. Cryopreservation is the method for germplasm storage using liquid nitrogen at temperature of -196oC This experiment aimed to obtain the growth ability of papaya lateral shoots to produce somatic embryos after being stored by cryopreservation. The experiment was designed in factorial by Completely Randomized Design with two factors.The first factor was the immersion time duration in PVS2 as cryoprotectant solution with 5 treatments of immersion duration of 0, 10, 20, 30, and 40 minutes. Second factor was culture medium for cultivated the lateral shoot which was added with plant growth regulators such as BA (benzyl adenine) and NAA (naphthalene acetic acid) at levels of 0, 1, 2, 3, and 4 mg l-1, respectively. The results showed that the immersion of lateral shoot in cryoprotectants for 10 and 20 minutes gave the better plantlet survival rate after discharge from liquid nitrogen, while the treatment of culture media had not been significant difference.

Abstract

Ariyanto D, Bengen DG, Prartono T, Wardiatno Y. 2018. Short Communication: The relationship between content of particular metabolites of fallen mangrove leaves and the rate at which the leaves decompose over time. Biodiversitas 19: 780-785. Fallen mangrove leaves contain metabolites that play a role in their decomposition in coastal conditions. This research was conducted from September 2016 to February 2017 in Pasar Banggi, Rembang, Central Java, with the purpose of investigating the impact of the leaf metabolites of various mangrove species on the rate of decomposition of the leaves in exposed litter bags The results suggested that secondary metabolites are closely involved in the decomposition of the mangrove leaves. The fastest rate of decomposition was found in Avicennia marina, and the slowest in Rhizophora stylosa. The leaves of A. marina required 10 days (half-life, t50) to decompose by 50% and this was closely related to the phosphorus content of the leaves. On the other hand, R. stylosa required 24 days (half-life, t50) to decompose by 50%.

Abstract

Hidayati N, Hamim H, Sulistyaningsih YC. 2018. Phytoremediation of petroleum hydrocarbon using three mangrove species applied through tidal bioreactor. Biodiversitas 19: 786-792. Mangrove is important component in coastal ecosystems that often faces environmental pollution including industrial waste, particularly oil waste (petroleum hydrocarbon). This study was aimed to analyze the growth, anatomical, and physiological responses of three mangroves species to petroleum hydrocarbon contaminant applied using tidal bioreactor (ebb flow system) as a model of sea-shore environmental condition. The experiment was carried out using completely randomized design with two factors i.e.: three species of mangrove (Rhizophora sp., Avicennia sp. and Bruguiera sp.) and four levels of petroleum concentration (0%, 10%, 20% and 30%) exposed using tidal bioreactor for 30 days. The parameters observed in this experiment were plant viability, total petroleum hydrocarbon (TPH) of media, plant growth, pH of media and roots malondialdehyde (MDA) content. Leaf anatomy was also analyzed to distinguish accumulation and translocation of oil compounds into leaf tissues. After 30 days of treatments, Rhizophora sp. had the highest viability and was able to reduce the higher level of TPH in the media compared to those of Avicennia sp. and Bruguiera sp. Petroleum hydrocarbon treatment caused the decrease of shoot and root growth of all species, as well as pH of the media, while it significantly increased malondialdehyde of the roots. Anatomical data showed that petroleum hydrocarbon was absorbed and translocated into the guard cell of the stomata. The result shows that Rhizophora sp. was the most tolerant mangrove species to petroleum hydrocarbon compared to Avicennia sp. and Bruguiera sp., indicated by its survival, the decrease of petroleum hydrocarbon in the sediment, and lower MDA content.

Abstract

Sari QW, Siswanto E, Setiabudidaya D, Yustian I, Iskandar I. 2018. Spatial and temporal variability of surface chlorophyll-a in the Gulf of Tomini, Sulawesi, Indonesia. Biodiversitas 19: 793-801. The Gulf of Tomini (GoT) is mostly influenced by seasonal and interannual events. So, the immensive aim of this study is to explore spatial and temporal variations of chlorophyll-a (chl-a) and oceanographic parameters in the GoT under the influences of monsoonal winds, El Niño Southern Oscillation (ENSO), and Indian Ocean Dipole (IOD). The data were collected from the satellite imaging of chl-a and sea and surface temperature (SST) as well as surface wind from the reanalysis data for a period of January 2003 to December 2015. Monthly variations of the chl-a and SST in the GoT reveal chl-a bloom in the center part to the mouth of the GoT during the southeast monsoon season (boreal summer). The chl-a concentrations were relatively higher (>0.1 mg m-3) and distributed throughout most of the areas near the Maluku Sea. The SST in the middle of the GoT was relatively lower than that near the Maluku Sea (the eastern part of the GoT). On the other hand, during the northwest monsoon (boreal winter), the chl-a concentration decreased (<0.1 mg m-3). During this season, the SST was relatively higher (28-29 °C) than that during the boreal summer (27-26 °C) and distributed uniformly. Meanwhile, on interannual timescale, the ENSO and IOD play important role in regulating chl-a distribution in the GoT. High surface chl-a concentration was observed during El Niño and/or positive IOD events. Enhanced surface chl-a concentration during El Niño and/or positive IOD events was associated with the upward Ekman pumping induced by the southeasterly wind anomalies. The situation was reversed during the Niña and/or negative IOD events.

Abstract

Amir A, Darwin E, Juniarto AZ. 2018. Effects of mobile phone exposure to SRY gene in Rattus norvegicus. Biodiversitas 19: 802-808. Mobile phones are low power radio devices, which transmit and receive radio frequency radiation in the microwave spectrum ranging from 900-1,800 MHz through an antenna used closely to the user’s head. Radiation destructs living tissue by altering structure of cell and damaging the DNA, damaging of genetic material in reproductive cells causes mutations and affecting to the next generation. The genetic database of mutation in human SRY gene has been collected and had the correlation between mutation and the occurrence of sex development disorder (translocation). However, the study focussing on SRY gene mutation to the exposure of mobile phone has not been studied, yet. This study was aimed to investigate the effect of various time exposure of mobile phone toward the characteristic of SRY gene fragments in Rattus norvegicus. Experimental research with randomized post test only control design was conducted on 20 Wistar aged 2-3 months with 200-250 grams of weight. Samples were divided into four groups, with three treatment groups based on radiation exposure time (30, 60, and 90 minutes), and one group as control group (without treatment) for 60 days. Following exposure, DNA was isolated from blood of rat, and amplified with a pair of SRY primer set. Positive DNA of SRY gene was assessed by sequencing the genes and determining the mutations. There were three single nucleotide polymorphism (SNP) of SRY gene in histidine 38 glutamine, (CAT> CAG), proline 76 threonine (CCT >ACT) and leucine 102 leucine (CTG >TTG). Long duration of radiation exposure for 90 minutes increased the risk of SRY gene mutation.

Syafutra R, Adi W, Iqbal M, Yustian I. 2018. Short communication: Dugong dugon Müller, 1776 (Sirenia, Dugongidae) in Bangka Island, Indonesia. Biodiversitas 19: 823-830. Dugong dugon is a marine mammal species classified as Vulnerable. It has distribution in Indonesia, especially in Bangka Island. However, only four records of dugong were reported in Bangka Island in 1976, 2006, and 2007. In addition, there is little published information about local beliefs toward dugong and awareness actions toward dugong conservation in Bangka Island. This research compiled new records of dugong, local beliefs toward dugong, and awareness actions toward dugong conservation in Bangka Island. Sixteen new records of dugong were collected in Bangka Island leading to a total of 18 records for this island. All new records of dugong were obtained entirely from the eastern waters of Bangka Island. The new records also informed that most of the dugongs were found dead and entangled in gill nets. In addition, an interesting local belief caused Kurau Village becomes the most important location for fishermen to sell dead dugongs or dugongs’ meat. Furthermore, three main awareness actions toward dugong had been implemented in Bangka Island in 2017.

Abstract

Amatta E, Calcaterra LA, Giannoni SM. 2018. Ant species (Hymenoptera: Formicidae) in the three forests of the Ischigualasto Provincial Park, a protected area of the Monte Desert, Argentina. Biodiversitas 19: 831-839. Deforestation and over-grazing mediated by the humans have caused a serious process of desertification in the Argentine Monte Desert, which threats biodiversity of this ecosystem. Forests provide important resources and refuge for animal species, such as ants. The objective of this work was to survey the ant fauna of dryland forests of Ischigualasto Provincial Park, a protected area located in the hyper-arid Monte Desert ecoregion in the province of San Juan, Argentina. Ant species were surveyed in summer in three types of forests (Prosopis, Ramorinoa and Bulnesia forests), using a combination of sampling methods: pitfall-traps, baiting, and hand collection. A total of 33 ant species were collected, of which 17 are new records for the Monte Desert and Dry Chaco and 24 for the San Juan province. The species richness is within the range reported for other Argentine desert and semi-desert areas. Prosopis forest was the richest with 32 species (24 exclusive), followed by Ramorinoa and Bulnesia forests with 11 and 4 species, respectively. This study contributes to improve the knowledge of ant fauna in desert habitats of the world, especially those inhabiting Prosopis forests, which are the most important ant diversity hotspots within the hyper-arid desert.
