Abstract

Anna Z, Saputra DS. 2017. Economic valuation of whale shark tourism in Cenderawasih Bay National Park, Papua, Indonesia. Biodiversitas 18: 1026-1034. The whale sharks aggregation in the waters of Cenderawasih Bay has an impact on improving the marine tourism industry in the region. On the other hands, Whale Shark is one of the species listed in the Red List of Threatened Species by the International Union for Conservation of Nature (IUCN), the vulnerable status, means that a whale shark populations have been reduced by 20% to 50% within 10 years or three generations. The decline numbers of whale sharks caused by human activities that damage the fish and the habitat, such as fishing and tourism activities. This is due to the lack of public awareness about the function and value of these resources and its habitat. The whale shark has inherent value as marine resources, and has an environmental services value, in relation to tourism activities. This paper measures the economic value and environmental services of the whale shark and its habitat. The method of Travel Cost is used to calculate the value of expenditures incurred by both foreign and local tourists. The study also measured the value obtained by tourist operators, the value of fishing activities, and the value of the habitat, through the people's Willingness to Pay (WTP), using Contingent Valuation Method (CVM). From the result of the overall economic valuation can be determined the estimated value of whale shark tourism, as well as Cenderawasih Bay National Park area, amounted to IDR 35.5 trillion. The policy implication of this research is the need for appreciation of the whale sharks value, as well as its habitat, by managing and developing conservation areas, and community capacity building on the understanding of the importance of whale sharks and its conservation.

Abstract

Susanto D, Hayatudin, Setiawan A, Purnomo H, Ruhiyat D, Amirta R. 2017. Characterizing nutrient status and growth of Macaranga gigantea in tropical rainforest gaps after selective logging in East Kalimantan, Indonesia. Biodiversitas 18: 996-1003. Selective logging caused the formation of forest gaps, which stimulate the growth of the pioneer tree species. This study aims to determine the characteristic of soil nutrients status and plant growth of Macaranga gigantea in the tropical rainforest gaps after selective logging in East Kalimantan, Indonesia. We established research plots 50mx50m in natural forest production, 1 until 10 years after selective logging. The measured data of each plot is the number of trees of M. gigantea, its stem diameter, and its height, and also the soil and leaf nutrient concentration. The results showed that the soil has a pH (H2O) of 5.3 ± 0.27, cation exchange capacity of 10.6 ± 2.98 meq. 100 g-1, base saturation of 27.7 ± 10.44%, while the concentration of nutrients carbon of 1. 04 ± 0.27%, nitrogen of 0.10± 0.02%, phosphorus of 6.35 ± 3.4%, potassium of 67.15± 30.1%, calcium of 1.7 ± 1.09% and magnesium of 0. 99 ± 0.8%. The highest stem diameter and height of M. gigantea (19.5 cm; 18.07 m) was obtained in plots of 8 years after selective logging and then declined, while the highest diameter increment and height increment obtained in plants located in a plot of 4 years after selective logging and decline until 10 years after selective logging. The concentration of nutrients accumulated in the leaves of M. gigantea was N with 1.51 ± 0.19%, P with 0.16 ± 0.01%, K with 1.37 ±0.28%, Ca with 1.78 ± 0, 43% and Mg with 1.53 ± 0.37%. The soil nutrients concentration of N, K, Ca and Mg correlated with plant growth of M. gigantea (p? 0.05), potassium concentration of soil positively correlated with a potassium concentration of leaves (p? 0.05), whereas magnesium concentration in the leaf correlated with plant growth (p? 0.05). We suspect that bases nutrient elements, potassium, calcium, and magnesium are nutrients absorbed in large quantities by M. gigantea and extremely important to its growth.

Abstract

Roesma DI, Tjong DH, Munir W, Agesi AV, Chornelia A. 2017. Genetic diversity of Tor douronensis (Pisces: Cyprinidae) in West Sumatra, Indonesia. Biodiversitas 18: 1018-1025. A random amplified polymorphic DNA-polymerase chain reaction (RAPDPCR) analysis was applied to determine the genetic diversity within and among the populations of Tor douronensis in West Sumatra river system. The results provided information for proper breeding, maintenance, and conservation of T. douronensis. The highest and the lowest values of genetic diversity were the population of Batang Matur (H = 0.1571; I = 0.2411) and Batang Malalo (H = 0.0880; I = 0.1353), respectively. The value of genetic differentiation (GST) was 0.4266 while that of heterozygosity between populations (DST) and within a population (HS) was, respectively, 0.088 and 0.1184. The value of gene flow between populations (Nm) was 0.6721. Grouping of individuals in a population based Principal Coordinates Analysis (PCO) and UPGMA was in line with the genetic distance values. Matur and Malalo were the most closely related populations (0.0174) while Batang Gumanti and Batang Sinuruik were the most distantly related populations (0.1918). The genetic variation between populations was lower than the genetic variation within the population of T. douronensis and population of Matur is recommended to be used as brood stock in the procurement of stock.

Abstract

Abd Rabou AN, Radwan ES. 2017. The current status of the date palm (Phoenix dactylifera) and its uses in the Gaza Strip, Palestine. Biodiversitas 18: 1047-1061. The date palm (Phoenix dactylifera L.) is considered one of the most important fruit crops in Palestine. It has a major socio-economic importance due to its commercial, nutritional, environmental, social, health and religious values. Because of its importance as a resistant and strategic crop facing serious local threats like pest infestation, underdeveloped marketing and mismanagement, the current study comes to investigate the status of the date palm tree and its uses in the Gaza Strip. Field surveys and institutional visits were applied to fulfill the purpose of the study. The current study revealed a total number of 250,000 trees of date palm existing in the Gaza Strip, with 40% of the dates is concentrated in the Middle Governorate. At least, 19 cultivars have been recorded locally with the ‘Hayani’, ‘Barhee’ and ’Bentaisha’ being the most common. The average date production in the last few years was 12,000 - 15,000 ton per year. More than 40 industries and uses associated with the date palm tree have been observed in the Gaza Strip, with the handicraft production and food industries are the main creative uses by the Palestinian community. Finally, the study recommends the improvement of the processes of date palm cultivation, production, protection, and marketing. The cooperation of different parties is very essential to ensure good sustainable development and uses of the date palm in the Gaza Strip, Palestine.

Abstract

Fitmawati, Fauziah R, Hayati I, Sofiyanti N, Inoue E, Matra DD. 2017. Phylogenetic analysis of Mangifera from central region of Sumatra using trnL-F intergenic spacer. Biodiversitas 18: 1035-1040. Mangifera from Central Sumatra has an unique ability to adapt to the high rainfall regions. This genus is therefore as a potential germplasm source in Sumatra. The aim of this study was to analyze and compare the nucleotide sequences of Mangifera in the central region of Sumatra based on gene loci of trnL-F intergenic spacer. The initial step of research was conducted by isolating DNA from leaves sample of Mangifera based on CTAB method. Sequences of gene loci of trnL-F were analyzed with Maximum Parsimony and Neighbour Joining methods through PAUP* Program version 4.0b10. From the results of sequences analysis with Maximum Parsimony method, it was obtained a monophyletic group of Mangifera consisted of two main clades which separated M. kemanga from five other species of Mangifera, i.e. M. foetida, M. odorata, M. laurina and Mangifera sp. Parsimony analysis also revealed that the common ancestor of M. kemanga is the first species appeared in the central region of Sumatra. The result of Neighbour Joining analysis showed M. laurina had the longest genetic distance among examined species and might be assumed as the most primitive species of Mangifera. Mangifera laurina and M. odorata were closely related as well as M. foetida and M. odorata. The results of research also revealed and supported the genus Mangifera as a monophyletic group.

Rismaya, Azamris, Budiarti S, Desriani. 2017. Housekeeping gene as a source of calibrator candidate for HER-2 scoring in frozen tissue breast cancer study based on qPCR. Biodiversitas 18: 1041-1046. HER-2 amplification in breast cancer gives an implication in therapy and prognosis. FDA have been approved Fluorescence In situ hybridization (FISH) for HER-2 amplification and immunohistochemistry (IHC) for protein expression measurement. In this recently times, quantitative PCR techniques have been reported as an alternative method for HER-2 amplification determination. Here in this report, we investigated new reference gene coming from housekeeping gene as an alternative calibrator for HER-2 amplification scoring based on qPCR methods. We compared two recommended housekeeping gene, 18S rRNA and ?-Actin, as a candidate for a HER-2 calibrator. For methods development, optimization and comparison study between 18S rRNA and ?-Actin, we used non-invasive samples (DNA buccal cells). Selected candidate reference further was tested to eighteen breast cancer sample, validated with qPCR methods refer to Mendoza et al. 2013. ?- Actin is shown as the best candidate for HER-2 scoring status determination. qPCR concordance result with other qPCR methods refers to Mendoza et al. 2013 shown 94.4%. The qPCR efficiency and % CV value shown as a requirement as a theory. qPCR efficiency was 103.8-105.3% for ?-Actin and HER-2 respectively while CV value was around 1.2%. Our result showed a significant correlation with reported methods, which could potentially complement with FDA approved methods.

Abstract

Nurfadilah S. 2017. Population study of Peristylus goodyeroides (Orchidaceae) in five habitats and implication for its conservation. Biodiversitas 18: 1084-1091. Many orchids have experienced population decline because of natural and anthropogenic disturbances and the remaining populations occur in fragmented habitats. The present study aimed to investigate (i) population of a terrestrial orchid, Peristylus goodyeroides (D. Don) Lindl., in terms of its demography, population size, and plant size, and (ii) characteristics of vegetation surrounding P. goodyeroides and its effect on the population size of P. goodyeroides (iii) environmental factors (litter thickness and soil pH) and their effects on the plant size of P. goodyeroides in five habitats. Number of individuals, plant height and leaf area of P. goodyeroides, surrounding vegetation, litter thickness, and soil pH were recorded in each habitat. The results showed that there was variation in the demographic structure of the population of P. goodyeroides in five habitats. Furthermore, three habitats of P. goodyeroides had small population size and small plant size compared to the other two habitats that had relatively larger population size and plant size. Small population size was correlated with taller vegetation surrounding P. goodyeroides reducing light availability for P. goodyeroides, while small plant size was related to sparse and thin litter cover causing low soil moisture and lacking nutrient availability for P. goodyeroides. Soil pH between habitats was similar and did not affect P. Goodyeroides plant size. The present study has implication on the conservation of P. goodyeroides for the improvement of population performance for the increase in population size and plant size for the species survival.

Abstract

Lestari DA, Azrianingsih R, Hendrian H. 2017. Taxonomical position of Annonaceae species from East Java, Indonesia: collections of Purwodadi Botanic Garden based on morphological character. Biodiversitas 18: 1067-1076. Morphological characters are one of the most consistent of taxonomical markers are used in Annonaceae today. One of the plants collections from Annonaceae species which came from East Java and conserved in Purwodadi Botanic Garden-Indonesian Institute of Sciences, Purwodadi, and East Java has some problems in morphological characters. It has some problems that causing the taxonomical position of these species are not clear, i.e. presence of unidentified plant until level species. The aim of this study is to classify and identify of species that have not been identified in order to taxonomical position be clearly. Material samples are used Annonaceae collection from East Java and Magnoliaceae as out-group. Samples of these plants were observed qualitatively and quantitatively through morphological characters were analyzed using cluster analysis and then synapomorphy, autapomorphy and apomorphy character analysis to identify and to determine the taxonomical position. The results showed that there are 4 tribes and two sub-families in the dendrogram. Tribe includes Miliuseae, Xylopiae, Annoneae and Uvariae, as well as sub-family of Malmeoideae and Annonoideae. Sub-family distinguished by inner petal and habit, sub-family of Malmeoideae has connate inner petals and trees habit, sub-family of Annonoideae has free inner petal and woody climber habit, some of the trees. Species are unidentified suspected as a different species based on the proximity of group formed. There are five plant species that have not been identified to the species level. These species can be recommended the taxonomical position and proposed of species name through dendrogram with the name of the specimen. Specimen 1 is predicted to have close relations with Annona muricata, specimen 2 is predicted to have close relations with Miliusa macropoda, specimen 3 is predicted to have close relations with Artabotrys uncinatus and identified as Uvaria micrantha, specimen 4 is predicted to have close relations with Fissistigma latifolium and specimen 5 is predicted to have close relations with Saccopetalum horsfieldii, because these species are in one group.

Abstract

Phinyo K, Pekkoh J, Peerapornpisal Y. 2017. Distribution and ecological habitat of Scenedesmus and related genera in some freshwater resources of Northern and North-Eastern Thailand. Biodiversitas 18: 1092-1099. The family Scenedesmaceae is made up of freshwater green microalgae that are commonly found in bodies of freshwater, particularly in water of moderate to polluted water quality. However, as of yet, there have not been any studies on the diversity of this family in Thailand and in similar regions of tropical areas. Therefore, this research study aims to investigate the richness, distribution and ecological conditions of the species of the Scenedesmus and related genera through the assessment of water quality. The assessment of water quality was based on the physical and chemical parameters at 50 sampling sites. A total of 35 taxa were identified that were composed of six genera, i.e. Acutodesmus, Comasiella, Desmodesmus, Pectinodesmus, Scenedesmus and Verrucodesmus. Eleven taxa were newly recorded in Thailand. The taxa were found in the oligo-mesotrophic to the eutrophic status. The major study sites were influenced by the nutrients identified in the water resources. The dominant species were Desmodesmus communis (E. Hegewald) E. Hegewald, D. armatus var. bicaudatus (Guglielmetti) E. Hegewald, D. armatus (Chodat) E. Hegewald and D. serratus (Corda) S. S. An, Friedl & E. Hegewald. This study has produced revised material on Scenedesmus and related genera in Thailand that is considered important information with regard to the classification of microalgae in Thailand.
