Abstract

Murwantoko, Negoro SLC, Isnansetyo A, Zafran. 2018. Short Communication: Identification of marine leech and determination of its prevalence and intensity on cultured hybrid groupers (Epinephelus sp.). Biodiversitas 19: 1798-1804. Grouper is an important fish species due to its high price both in domestic and international markets. Several hybrid groupers have been produced and can be accepted in market. A major production constraint in grouper culture is mortality due to diseases. Leech is an ectoparasite for groupers which may cause significant loss. The aims of this study were to identify and to assess the prevalence and intensity of leech on hybrid grouper cultured in sea cages at Buleleng waters. Morphological identification was conducted using fresh and stained specimens while molecular identification was conducted using nucleotides sequence of mitochondrial cytochrome oxidase subunit I (COI). The presence of leech was observed by unaided observation of 14 populations of hybrid grouper. Morphological identification showed that the leech belonged to Zeylanicobdella arugamensis. This result was also supported by analysis of COI sequence that showed 100% homology with Z. arugamensis (accession number KY 441721.1) and 90% homology with Aestabdella abditovesiculata (accession number DQ414300.1). Hybrid groupers at sea cages were infected by leeches with prevalence and intensity, respectively, of 100% and 21.2 leeches fish-1. The prevalence and intensity were varied depending on the farm and population. Cantik grouper was more susceptible to leech infection than cantang grouper. The bigger fish tended to have higher leech prevalence and intensity.

Abstract

Arianto W, Zuhud EAM, Hikmat A, Sunarminto T, Siregar IZ. 2018. Genetic diversity of Amorphophallus titanum in Bengkulu, Indonesia based on RAPD markers. Biodiversitas 19: 1783-1790. Titan Arum [Amorphophallus titanum (Becc.) Becc. Ex Arcang], a plant species belonging to the family of Araceae is known for its gigantic floral size and elicited rotten fragrance when the flower bloom. Since it remains only found in Sumatran island, many authors categorized the plant as endemic species. The population of the species in the natural habitat has significantly declined because of the conversion of forest land mainly into plantations or other land uses. Considering the importance of conservation attempts to A. titanum, a sufficient data on genetic diversity of the species is necessary. The research was aimed to determine the genetic diversity within and among populations of A. titanum in some area of protected forests in Bengkulu Province, comprising the population of Palak Siring, Tebat Monok, and Air Selimang. RAPD genetic DNA fingerprinting approach was used to assess the genetic diversity of A. titanum using 13 preselected DNA primer: OPA 11, OPA 19, OPC 04, OPN 14, OPN 19, OPU 03, OPU 06, OPU 07, OPB 17, OPC 07, OPO 04, OPU03-1, OPNI 18E. The result revealed that the method has successfully produced several DNA fragments with varied length ranging from 250 bp to 2000 bp with 4-16 variation in polymorphic bands. Based on RAPD marker analysis, the population of Air Selimang was considered as a potential center of diversity of A. titanum because of the others two populations had a lower genetic diversity. In general, the genetic diversity among populations was lower than within population. The cluster analysis of the genetic similarity of 22 individuals of the three populations resulted in the separation into two main groups with the first group consisting of 17 individuals (Population Air Selimang and Tebat Monok) and the second group of 5 individuals (Palak Siring population).

Abstract

Pitoyo A, Prameta AA, Marsusi, Suratman, Suranto. 2018. Morphological, anatomical and isozyme variability among taro (Colocasia esculenta) accessions from southeastern part of Central Java, Indonesia. Biodiversitas 19: 1811-1819. The objective of this study was to evaluate morphological, anatomical and isozyme variability among taro accessions from southeastern part of Central Java (Indonesia). A total of 20 taro accessions were collected from a wide range of sites during field surveys. Morphological characters measurements were taken on vegetative structures such as roots, stems, leaves, and corms. Anatomical characters were observed from both paradermal and transverse sections of leaf. Identification of biochemical markers was done by using peroxidase and esterase isozyme system. A UPGMA dendrogram among accessions was constructed based on the genetic similarity matrix by applying a cluster analysis using a computer programme, NTSYS Version 2.00. The analysis of variance for morphological and anatomical characters revealed that there was significant difference for majority of the tested traits indicating that there was a variability among the taro accessions. Polymorphism was observed using isozymes of esterase (12 banding pattern) and peroxidase (8 banding pattern). Based on the dendrogram at a level of 62 % similarity, taro accessions were segregated into two major clusters. In Cluster I, the closest relationship was shown between SKH and SKA accessions that had 96 % coefficient of similarity. The ten accessions from Klaten, Sragen, and Karanganyar were then clustered separately as Cluster II with coefficient of similarity 73.52 %.

Abstract

Setiawan H, Wardhani HAK, Kamaludin, Hutagaol RR, Afriani R. 2018. The diversity of Nepenthes at the post-mining area in Sintang District, West Kalimantan, Indonesia. Biodiversitas 19: 1820-1827. Nepenthe is a tropical pitcher plant found in Indonesian archipelago and lives in nutrient leak habitat. One of Nepenthes nutrient leak habitat commonly found in Kalimantan Island is the post-mining area. This research aimed to know the habitat condition, species composition, species richness and diversity index of Nepenthes in Post-mining area in Sintang District, West Kalimantan Province. Thirty plots, each measuring 5 x 5-meter square, were established to survey the Nepenthes diversity in five locations of the post-mining area in Sintang District. There were 910 individuals of Nepenthes found spreading in two sub-Districts and five areas. Habitat condition in the post-mining area tended to be high in light intensity and temperature but low in humidity. Five Nepenthes species were found, namely N. ampullaria, N. bicalcarata, N. gracilis, N. mirabilis, and N. rafflesiana. Four natural hybrids were also found including N. xhookeriana, N. xkuchingensis, N. xneglecta, and N. xtrichocarpa. The species richness in post-mining area were 1.25 in Danau BTN (Bank Tabungan Negara/State Savings Bank) 0.95 in Dusun Kerangas, 0.58 in Sungai Ana Village, 0.21 in Jerora 1 and 0.20 in Danau Baning. The diversity index in Danau BTN, Dusun Kerangas, Sungai Ana, Jerora 1 and Danau Banning area were of low levels, respectively, 1.66, 1.3, 1.0, 0.64, and 0.68. Cluster analysis of species richness, diversity index, and abiotic factors showed that Danau Baning-Sungai Ana-Jerora 1 was grouped in the same cluster while Danau BTN and Dusun Kerangas were in a separate cluster.

Pourrahmati G, Mataji A, Pourbabaei H, Salehi A. 2018. Short Communication: Floristic composition and relationships between plant species abundance and soil properties in common hazel (Corylus avellana) mountainous forest of northern Iran. Biodiversitas 19: 1835-1841. Mountainous forests are valuable terrestrial ecosystems because of their useful services for the human being. Here, we explored the floristic composition and the relationships between plant species abundance distribution and soil physical and chemical properties in common hazel (Corylus avellana L.) in the mountainous forest of northern Iran. Within the forest stand, 30 quadrats (20 m × 20 m and 1 m × 1 m for woody and herbaceous species, respectively) were selectively sampled along an altitudinal range from 1300 m to 1800 m a.s.l. to assess plant species composition and abundance, and soil samples were taken to perform chemical and physical analyses. The results showed that a total of 43 herbaceous and 15 woody species belonging to 23 and 8 families were identified. The abundance of herbaceous species was significantly correlated with soil properties (pH and total N). Furthermore, the abundance of woody species had a non-significant correlation with soil properties.

Abstract

Bin-Salman SA, Amasha RH, Jastaniah SD, Aly MM, Altaif K. 2018. Isolation, molecular characterization and extracellular enzymatic activity of culturable halophilic bacteria from hypersaline natural habitats. Biodiversitas 19: 1828-1834. Saline habitats, like the Dead Sea, are unusual extreme environments, due to their extreme salinity. Most saline habitats originate from the evaporation of seawater, and have a nearly neutral to slightly alkaline pH (such as the Red Sea (pH8.3) and Arabian Gulf, pH8.3). Ten halophilic bacterial strains (two Gram-negative) belonging to the family of Halomonadaceae and (eight Gram-positive), belonging to the family of Bacillaceae, were isolated from the Red Sea, Arabian Gulf, and Dead Sea by subjecting the isolates to a high salinity medium, followed by identification using 16S rRNA gene sequencing. Four of isolates were designated on the basis of their tolerance to high salinity; SBR1 exhibited 97% homology to Halomonas aquamarina, SBR2 showed 97% homology to Sediminibacillus sp., (Red Sea), SBA9 exhibited 94% homology to Halobacillus sp., (Arabian Gulf) and SBD17 gave 98% homology to Halobacillus dabanensis (Dead Sea). The isolates were also characterized by their physiological parameters, SBR1 showed optimum growth at 30°C, pH8.5 and1.5M NaCl, SBR2 at 30°C, pH6.0 and 1M NaCl. Optimum conditions for SBA9 were 35°C, pH6.5 and 1M NaCl and for SBD17, 37°C, pH7.0 and 1M NaCl.

Abstract

Mukhlisi, Ningsih TS, Sari UK, Kurniawan Y, Setiawan R, Muslim A. 2018. Habitat utilization of the Sumatran rhinos (Dicerorhinus sumatrensis harrissoni) in Kutai Barat forest, East Kalimantan, Indonesia. Biodiversitas 19: 1842-1850. Sumatran rhino population in Kutai Barat forest faces a high threat of extinction. Conservation efforts can be developed more effectively and efficiently by understanding the condition of their natural habitat. This study aimed to analyze various factors influencing habitat utilization of the Sumatran rhino in Kalimantan, specifically in Kutai Barat forest. We used past survey data of rhino presence carried out by WWF from 2014 to 2016. GPS coordinates were recorded for all signs of rhinos, such as camera trap images, footprints, bites mark on food plant, dung piles, urine, scratch, twisting, and lying signs. Rhino occurrence GPS coordinates were plotted on a map of the Sumatran rhino's habitat distribution in Kutai Barat using a grid of 2 x 2 km2 size. Spatial analyses were run using ArcGIS 10.6. We used a habitat selection index formula to analyze habitat preference and biner logistic regression to develop Resources Selection Function (RSF). We found that the preferred habitat of the Sumatran rhino was in the secondary forest with medium and high vegetation densities. The most influential habitat variables on the presence of Sumatran rhinoceros in the Kutai Barat forest were the slope and distance from wallow. The Sumatran rhinoceros were more likely to be found in the sloping areas and the areas closer to the wallows.

Abstract

Sudarmono. 2018. Decreased populations of Scutellaria discolor and Plectranthus galeatus (Lamiaceae) on Mount Gede, West Java, Indonesian and its surrounding. Biodiversitas 19: 1866-1870. Scutellaria discolor Colebr. and Plectranthus galeatus Vahl. are herbs belonging to mint family (Lamiaceae) which have the potential to be used for medicinal purposes. However, their population is gradually declining. The population of the two species are now only found in the mountains or highlands or the edges of the forests that are still protected, i.e. Mount Gede and Telaga Warna protected forest. This research aimed to know the condition of parent and seedling population of Scutellaria discolor Colebr and Plectranthus galeatus Vahl. on Mount Gede and Telaga Warna vicinities, West Java Province, Indonesia. The research method used was parallel transect lines. Association of the existing plants in the vicinity of the area were also observed. In Mount Gede at altitudes about 1200 m above sea level there are 203 seedlings and 167 parents of S. discolor species, while there are 69 seedlings and 11 parents of P. galeatus. This is higher than the populations of 1100 m altitude, i.e. there are 76 seedlings and 45 parents of S. discolor and 12 seedlings and 9 parents of P galeatus. In Telaga Warna, S. discolor exist only at altitudes about 1500 m asl., i.e.. 47 seedlings and 52 parents. While for P. galeatus, there are 37 seedlings and 31 parents at altitudes about 1500 m. At altitude below 1400 m, there are 18 seedlings and 8 parents, this is very rare. Populations of S. discolor and P. galeatus in Mount Gede at an altitude between 1100-1300 m asl is a balance between the seedlings and its parent population which is the same for seedling populations of S. discolor in Telaga Warna at an altitude of 1400-1500 m asl, but for P. galeatus seedling number decreases from an altitude of 1400 to 1500 m asl.

Abstract

Gebreegziabher BG, Tsegay BA. 2018. Evaluation of farmers’ knowledge on the rare Abyssinian pea (Pisum sativum var. abyssinicum) landraces of Ethiopia. Biodiversitas 19: 1851-1865. Abyssinian pea (Pisum sativum var. abyssinicum A. Braun) is a rare and problematic taxon requiring evaluation of present farmers’ local knowledge. Cross-sectional data were collected from 444 respondents and analyzed using SPSS software. Descriptive statistics was used; one way ANOVA for significance test of variance and Exhaustive CHAID growth method for predictions. Prediction results showed that the crop requires about two good rains, Nitisol soils and about 21-30 kg ha-1seeding rate. The flowering to maturity time ranges 11?2 to 21?2 months depending on the agroecology (highland or lowland), with a yield of about 300-400 kg ha-1on average. The crop distribution is currently limited to three to four districts and sown after other crops are harvested. Major factors hindering its distribution are agro-ecological suitability, lack of intervention and preference of high yielding pea varieties. The crops’ inferiority in yield and pest susceptibility is the main reason for less extensive awareness on the crop. Though inferior in yield and susceptible to pest, farmers still prefer to grow the crop because of its marketability for local exchange and consumption. The core production problems currently remarked by farmers are expensive price of the seed to buy and small land holding.

Abstract

Herliansyah R, Fitria I. 2018. Latent variable models for multi-species counts modeling in ecology. Biodiversitas 19: 1871-1876. High-dimensional multi-species counts are often collected in ecology to understand the spatial distribution over different locations and to study effects of environmental changes. Modeling multivariate abundance is challenging as we need to consider the possibility of interactions across species. Latent variable models are the recent popular approaches in statistical ecology to address such issue that has a similar framework to ordinary regression models. In this paper, we employed the poisson distribution for modeling count responses and a negative binomial distribution for more frequent zeros in observations. The implementation of a latent variable model, Generalized Linear Latent Variable Models (GLLVMs), was demonstrated on multi-species counts of endemic bird species collected in 37 different sites in Central Kalimantan, Indonesia. The main objectives were to study the effect of logging activities on abundance of endemic species and their interactions and to observe the habitat preference of certain species. Our study found that out of four endemic species, Alophoixus bres and Eurylaimus javanicus species were significantly affected by logging activities. The sign of parameters was negative indicating the logging activities in 1989 and 1993 bring significantly negative impacts on those species. The interaction created among species was strongly negative for major endemic species especially Alophoixus bres and Eurylaimus javanicus that prefer living in primary forest than in logging areas.
