Abstract. Boontanom P, Chantarasiri A. 2020. Short Communication: Diversity of culturable epiphytic bacteria isolated from seagrass (Halodule uninervis) in Thailand and their preliminary antibacterial activity. Biodiversitas 21: 2907-2913. Epiphytic bacteria are symbiotic bacteria that live on the surface of seagrasses. This study presents the diversity of culturable epiphytic bacteria associated with the Kuicheai seagrass (H. uninervis) collected from Rayong Province in Eastern Thailand. Nine epiphytic isolates were identified into four phylogenetical genera based on their 16S rRNA nucleotide sequence analyses. They are considered firmicutes in the genera of Planomicrobium, Paenibacillus and Bacillus, and proteobacteria in the genus of Oceanimonas. Three species of epiphytic bacteria preliminarily exhibited antibacterial activity against the human pathogenic Staphylococcus aureus using the perpendicular streak method. The knowledge obtained from this study increases understanding the diversity of seagrass-associated bacteria in Thailand and suggests the utilization of these bacteria for further pharmaceutical applications.

Abstract. Simanjuntak R, Yusniar M, Samalukang YM, Boleu FI, Mardiastuti A, Widyasari V, Udin JS. 2020. Short Communication: Egg harvesting and local conservation of Moluccan Scrubfowl (Eulipoa wallacei) in the Maluku Islands, Indonesia. Biodiversitas 21: 3018-3024.  This study was conducted at four locations in Central Maluku and North Halmahera, which have been used as nesting ground habitats of the Moluccan Scrubfowl (Eulipoa wallacei), an endemic bird of the Maluku Islands, Indonesia. The objective of this study was to record and analyze the egg harvesting and local conservation of Moluccan Scrubfowl in four locations in the Maluku Islands: Simau, Kao, Haruku, and Kailolo. The results showed that a relatively large number of harvested eggs were found in Simau (Halmahera Island) and Kailolo. In Kailolo, the total number of eggs harvested was 21,707 per year. The local community has the initiative to conserve this bird by establishing local regulations, called sasi. The Haruku community gave a portion of the eggs to Kewang, a customary institution authorized to manage the natural resources, to be hatched semi-naturally around the Kewang House. Likewise, the Salabia youth organization in Simau, together with landowners, developed a semi-natural hatchery for the Moluccan Scrubfowl eggs.

Abstract. Hasanah Y, Mawarni L. 2020. Exploration and identification of Anredera cordifolia morphological characters in the highlands and lowlands. Biodiversitas 21: 2759-2766. Information about genetic diversity and relationships between accessions is very important in plant breeding programs, because with the availability of this information, it is easier to determine relationship between accessions that can be used as a basis for plant selection. The objective of the research was to evaluate the morphological characteristics and relationship of binahong or Anredera cordifolia (Ten.) Steenis) accessions in the lowlands and highlands. The study was conducted in Karo (highlands) and Medan (lowlands), North Sumatra, Indonesia, from May to August 2019. This research used a descriptive method. Before the survey and exploration are conducted, first a pre-survey was conducted by gathering information from key informants and other informants. The characteristic of morphological diversity A. cordifolia can be distinguished based on leaf color, stem shape, axillary tuber, rhizome, and the presence of flowers. The dendrogram relationship between accessions is based on a genetic similarity matrix using cluster analysis. Analysis of qualitative morphological characters revealed the existence of variability among A. cordifolia accessions. There is a far relationship relation between A. cordifolia plants in Karo and Medan with Eucludian range of 0.446 to 57.725, hence resulting in two clusters that show differences in the variation of A. cordifolia plants. There is a distant relationship relation with M4 and M7 accessions with a dissimilar distance of 57,725 and the closest relationship with accession K1 and K2 with a dissimilar distance of 0.446. Therefore, morphological characterization in the research is valuable to understand the variability of genetic of A. cordifolia accessions in the lowland and highland in North Sumatra.

Abstract. Elfidasari D, Wijayanti F, Sholihah A. 2020. Trophic level and Position of Pterygoplichthys pardalis in Ciliwung River (Jakarta, Indonesia) ecosystem based on the gut content analysis. Biodiversitas 21: 2862-2870. The trophic level of an organism describes its sequence of natural diet visible to the food chain along with its ecosystem. This is also related to the type of diet composition and food fraction obtained by analyzing its gut content. The Pterygoplichthys pardalis from Ciliwung River show the diversity of the natural diet. The aims of this study is to determine the trophic level and position of P. pardalis in the Ciliwung River ecosystem based on gut content analysis using the purposive sampling method. Data were obtained from a total of 30 fishes from the Kalibata and Cawang areas through observations. The fishes were dissected, and gut contents were observed using a light microscope, with observations repeated 5 times of each sample. Data analysis includes relative length of gut, Index of Preponderance, area of the diet niche, niche area, niche overlap, and trophic level of an organism. The results showed that P. pardalis in Ciliwung River is at trophic level II, and included as herbivores (2.00 < troph < 2.90) that consist of Bacillariophyta (82.03%), Chlorophyta (12.7%), Cyanophyta (3.74%), Euglenophyta (1.19%), Amoebozoa (0.28%), and Dinoflagellata (0.68%).

Abstract. Hapsari L, Trimanto, Budiharta S. 2020. Spontaneous plant recolonization on reclaimed post-coal mining sites in East Kalimantan, Indonesia: Native versus alien and succession progress. Biodiversitas 21: 2003-2017. Comparative vegetation analyses subjected to recolonization of spontaneous plants were carried out in two post-coal mining reclamation sites, with different ages of reclamation, specifically 9 years old and 17 years old, in Bontang, East Kalimantan. This study aims to determine the spontaneous plant diversity and composition, identify the spontaneous alien plant species invasion (IAS), analyze the underlying micro-climates and soil factors and their association to the spontaneous plant recolonization, also to evaluate the succession progress. Results showed that both reclamation sites have undergone some vegetation and environmental improvements. The plant succession stage of both sites was identified at the same stage, as establishment phase of early-succession stage in transition to mid-succession stage. The spontaneous plants were comprised of two layers, i.e. (i) understories include grasses, ferns, lianas, herbs, shrubs and tree seedlings; and (ii) saplings include some of trees and small trees. Plant diversity indices on both sites were in moderate category. At understory layer, the 9-y.o. site was mostly dominated by grass Polytrias indica, whereas the 17-y.o. site was dominated by shrub Asystasia gangetica. At sapling layer, the 9-y.o. site was mostly dominated by Glochidion obscurum, whereas the 17-y.o. site was dominated by Macaranga tanarius. Dominant pioneer tree and shrub species in two reclamation sites mostly from general species component of secondary tropical forests from the families Euphorbiaceae, Phyllantaceae, Melastomaceae, Leguminosae, and Lamiaceae. It was recorded seven IAS in the 9-y.o. site, which six out of seven species were dominant. Meanwhile, in the 17-y.o. site was recorded eight IAS but only four species were dominant. Two dominant noxious weed species were also identified. Each IAS and noxious weed species has invasiveness traits that make them well-grown, successfully recolonized and invaded the reclamation site. Environmental factors include air temperature, air moisture, and light intensity; and soil conditions include pH, C/N ratio and physicochemical properties affected the variation of spontaneous plant establishment on each reclamation site. These comparative study findings may become inputs for coal mining operations management to evaluate and improve their reclamation program; such as by soil reconditions, controlling the populations of IAS, and planting more intensively of native tree species.

Abstract. Hartatie ES, Prihartini I, Widodo W, Wahyudi A. 2020. Short Communication: Detection of bioactive compounds in essential oil from lemongrass cultivated in Ngantang, Malang, East Java, Indonesia. Biodiversitas 21: 2821-2825. Lemongrass (Cymbopogon citratus) commonly known as West Indian lemongrass is a member of the Poaceae family and belongs to genus Cymbopogon. It is one of the plants commonly used in fresh form as a spice by the people in Indonesia and widely planted in the yard of the house. Lemongrass contains several bioactive compounds and it might be extracted to obtain essential oils useful for many applications such as flavor and fragrance ingredients, perfumery, cosmetics, food preservation, pharmaceutical. The chemical composition of essentials oil can be variable, according to the genetic diversity, habitat, weather, and cultural treatment. The aim of study was to investigate the bioactive compounds in essential oil from lemongrass stalk and lemongrass leaves which cultivated in Ngantang, Malang, East Java, Indonesia. Detection of bioactive compounds was carried out by gas chromatography-mass spectrometry (GC-MS). The results of study are the main compound in lemongrass essential oil was citral. There is a difference between the citral content of essential oils from lemongrass stalk compared to essential oils from lemongrass leaves, both in quantity and components. The citral (geranial and neral) content of essential oil made from stalk was higher than made from leaves, but the amount of bioactive compounds of essential oils from leaves more than from the stalk.

Abstract. Ashan MD, Miftahudin, Reflinur, Pabendon MB, Santoso SB, Salim A. 2020. QTL Mapping linked to downy mildew resistance genes in maize (Zea mays). Biodiversitas 21: 3735-3743. Downy Mildew (DM) caused by Peronosclerospora spp. is one of the most destructive diseases and problems in yield losses of maize production worldwide. Identification of molecular marker-linked to the DM resistance genes is considered as an important step in the improvement of the DM resistance nature in maize breeding program. The objective of the study was to identify molecular markers linked to the DM resistance genes in maize. A total of 198 F3 maize lines generated from a cross between R10-4430 and Kandora was used in microsatellite genetic map construction and the corresponding F3: 4 families were used in phenotypic evaluation to identify quantitative trait loci (QTLs) responsible for DM resistance-related trait. The entire genetic linkage map constructed with 28 SSR markers resulted in 460.3 cM with an average distance between markers of 26.85 cM. Seven main-effect QTLs controlling the DM resistance genes were identified in the entire genome map of F3 population with the phenotypic variation explained (PVE) values ranged from 43.35 to 53.71%. Among detected QTLs, three QTLs, qDM-Pp1a, qDM-Pp1b1, and qDM-Pp1b2 were detected on chromosome 1, one QTL, qDM-Pp5 was on chromosome 5, two QTLs, qDM-Pp6b1 and qDM-Pp6b2 were on chromosome 6 and one QTL, qDM-Pp10 was on chromosome 10. The effect of detected QTLs responsible for DM resistance trait ranged from 43.35 to 53.71% and those will be potential to be further used as molecular aided selection in maize breeding for DM resistance.

Abstract. Darmadi AAK, Suprapta DN, Khalimi K. 2020. Potential antagonistic rhizobacteria to control Colletotrichum scovillei, the cause of anthracnose disease in chili pepper. Biodiversitas 21: 2727-2734. Six species of Colletotrichum were identified as the cause of anthracnose disease on Bali Island, Indonesia in 2018. These species were C. scovillei, C. acutatum, C. nymphaeae, C. gloesporioides, C. truncatum, and C. fructicola. Among them, C. scovillei was the most prevalent at 55% of all samples tested. This study was conducted to find potential antagonistic rhizobacteria isolated from various rhizospheres of plants grown in Bali. A total of 1,040 rhizobacteria isolates were tested for their antagonistic activity against the growth of C. scovillei on potato dextrose agar. Results showed that 10 isolates inhibited the growth of C. scovillei by more than 80%. Among these isolates C1 and C7B possessed inhibitory activity at 94.9% and 94.3%, respectively. Molecular identification based on analysis of 16S rRNA gene showed that isolate C1 belonged to the species Paenibacillus polymyxa, whereas isolate C7B was identified as Bacillus siamensis. According to scanning electron serious damage on mycelia of C. scovillei was observed. Wrinkles were observed on mycelia of C. scovillei grown jointly with rhizobacterial isolate C1, whereas no wrinkle was observed on C. scovillei grown solely. Three compounds were detected in the hexane phase of cell-free filtrate P. polymyxa C1, namely, 3-hydroxy-2-butanone and 2,3-butanediol. These compounds may be responsible for antifungal activity against C. scovillei.

Abstract. Aiman WM, Yusoff FM, Arshad A, Kamal AHM, Ismail J, Idris MH, Karim NU, Asif AA. 2020. Distribution of zooplankton community in Toli shad (Tenualosa toli) habitats, Sarawak, Malaysia. Biodiversitas 21: 4022-4033. The river ecosystems of Sarawak has been identified as important-spawning ground for economically important Toli shad (Tenualosa toli) fisheries. In these river ecosystems, zooplankton serves as a secondary producer to the different types of fish larvae including Toli shad. The productivity and biomass of zooplankton are important factors to control the production of higher trophic level organisms like fish larvae and fishes in different stages including T. toli larvae. In this viewpoint, the composition and abundance of zooplankton were investigated at 5 (five) sampling stations (considered to be spawning and nursing areas of Toli shad) at Batang Lupar and Batang Sadong estuaries from July 2016 to June 2017. A total of 29 zooplankton taxa were recorded that belong to 14 major groups comprised of Copepoda (Arthropoda), Crustacean nauplii (Arthropoda), Fish larvae (Chordata), Mollusca (Mollusca), Luciferidae (Arthropoda), Cnidaria (Cnidaria), Ostracoda (Arthropoda), Cirripedia (Arthropoda), Polychaete larvae (Annelida), Chaetognatha (Chaetognatha), Appendicularia (Chordata), Amphipoda (Arthropoda), Echinodermata larvae (Echinodermata) and Cladoceran (Arthropoda). Copepod was dominant group of zooplankton (82.40-94.41%) at all stations, contributing 477.37-25921.89 ind/m3 and 88.38% of total abundance. The second highest was crustacean larvae (2.45-9.38%) in all stations, contributing 0-2391.7 ind/m3 and 5.88% of total abundance. Zooplankton abundance was higher at downstream station 1 (8460.72 ind/m³) followed by station 2 (5479.80 indi/m³), station 3 (4571.95 ind/m³), station 4 (4394.20 ind/m³) and upstream station 5 (4156.73 ind/m³). Canonical Correspondence Analysis showed that the abundance of copepods was highly influenced by total turbidity and nitrate in the riverine and estuarine ecosystems. Abundance of zooplankton was relatively higher (9549.31 ind/m³) during the post-monsoon and lower (3534.56 ind/m³) during the southwest monsoon.

Abstract. Susandarini R, Subandiyah S, Daryono BS, Rugayah. 2020. Microsatellite polymorphism for molecular characterization of pomelo (Citrus maxima) accessions from Indonesia. Biodiversitas 21: 2390-2395. Citrus maxima (Burm.) Merr. (pomelo) as a minor fruit crop deserve attention on its phenotypic and genotypic variability to avoid the risk of extinction. Previous study showed that pomelo from Indonesia has high morphological variability, and thus it is interesting to explore its genotypic variability using molecular markers. Microsatellite is a molecular marker widely used in Citrus taxonomy studies. This study aimed at revealing microsatellite polymorphism and its potential application in cultivar characterization of C .maxima. Eighty accessions of C. maxima consisting of registered cultivars and landraces from Indonesia were used in this study. Analysis of microsatellite sequences from genomic DNA amplified using DY296883 primer showed that C. maxima microsatellite has high polymorphism in the form of repeat length variation of (GA)n, ranging from (GA)7 to (GA)19. This study proved the existence of high genotypic variability in C. maxima, and confirmed the role of microsatellite as a useful molecular marker for uncovering variability at intraspecific level. Observation of the microsatellite polymorphisms indicated that variability of (GA)n can be used to distinguish some pomelo cultivars.
