Abstract. Eddy S, Basyuni M. 2020. The phenomenon of nipah (Nypa fruticans) invasion in the Air Telang Protected Forest, Banyuasin District, South Sumatra, Indonesia. Biodiversitas 21: 5114-5118. Disturbed mangrove forests such as the Air Telang Protected Forest (ATPF) do not have plant formation as natural mangrove forests and tend to be invaded by Nypa fruticans locally called nipah. The purpose of this study was to describe the phenomenon of nipah invasion in ATPF as a result of anthropogenic activities and its effects. The field survey was carried out by determining several sampling points according to the actual conditions of the area using the Geographic Information System/GPS. During field survey, data were collected in the form of descriptions and documentation of forest conditions, especially the distribution of nipah plants along with interviews with the local communities. It was known that nipah invasion occurred in the ATPF area due to anthropogenic activities where nipah thrives in open areas, both in tidal and land zones, as well as in pond areas. The invasion of nipah will have an impact on disturbing the balance of mangrove forest ecosystem functions due to changes in the physical, chemical, and biological conditions of the environment. However, nipah has various benefits that can be used by the local community, including the leaves, stems, and fruit, as well as the presence of worms that are associated with the nipah plant.

Abstract. Ng WS, Mohd-Azlan J, Wong SY. 2020. Floral biology and pollination strategy of Durio (Malvaceae) in Sarawak, Malaysian Borneo. Biodiversitas 21: 5579-5594. This study was carried out to investigate on the flowering mechanisms of four Durio species in Sarawak. The anthesis started in the afternoon (D. graveolens and D. zibethinus), evening (D. kutejensis) or midnight (D. griffithii); and lasted between 11.5 hours (D. griffithii) to 20 hours (D. graveolens). All four Durio species are generalists. Individuals of a fruit bat (Eonycteris spelaea, Pteropodidae) are considered as the main pollinator for D. graveolens, D. kutejensis, and D. zibethinus while spiderhunter (Arachnothera, Nectariniidae) is also proposed as a primary pollinator for D. kutejensis. Five invertebrate taxa were observed as secondary or inadvertent pollinators of Durio spp.: honeybee, Apis sp. (Apidae), stingless bee, Tetrigona sp. (Apidae), nocturnal wasp, Provespa sp. (Vespidae), pollen beetle (Nitidulidae), and thrip (Thysanoptera). Honey bees and stingless bees pollinated all four Durio species. Pollen beetles were found to pollinate D. griffithii and D. graveolens while nocturnal wasps were found to pollinate D. kutejensis and D. zibethinus. Thrips were found to pollinate D. griffithii only. Floral rewards include nectar, pollen and staminodes. The nectar production of D. graveolens, D. kutejensis, and D. zibethinus increased from the start of anthesis until just after midnight but decreased from then onwards. Durio griffithii produced consistent nectar concentration with inconsistent volume. Durio graveolens, D. griffithii, and D. zibethinus are partially self-incompatible.

Abstract. Lischer K, Putra ABRD, Guslianto BW, Avilla F, Sitorus SG, Nugraha Y, Sarmoko. 2020. Short Communication: The emergence and rise of indigenous thermophilic bacteria exploration from hot springs in Indonesia. Biodiversitas 21: 5474-5481. Indonesia is an archipelagic country located in the pacific ring of fire, and is estimated to cause numerous hot springs spread across the country. In addition, small living microbes have been explored in these locations since 1985. These microbes possess the ability to survive in areas with high temperature (more than 40oC-90oC), and are therefore termed thermophiles. Hence, massive explorations have been conducted on Java island and other unexplored areas at Sumatra to Papua in New Guinea islands. Moreover, a total of 71 hot springs characterized by the presence of thermophilic bacteria have been explored in Indonesia. These investigations ensue with various approaches, including through conventional and microbiological, 16S rRNA, as well as whole-genome sequencing methods. In addition to species exploration, the application of thermophiles has become a topic of interest from 1999, especially based on thermostable enzymes with the capacity to maintain activity at high-temperature conditions. These include amylase, protease, lipase, xylanase, esterase, and cellulase as the most common isolated form, which indicates the existence of significant extractable potentials. Hence, there is a need for further research in terms of both exploration and application purposes.

Abstract. Nisa IK, Prabaningtyas S, Lukiati B, Saptawati RT, Rodiansyah A. 2021. The potential of amylase enzyme activity against bacteria isolated from several lakes in East Java, Indonesia. Biodiversitas 21: 42-49. Indonesia is one country that has water resources having an abundance of microbial diversity, but not explored massively. This study aims to measure the amylase activity quantitatively from 53 amylolytic bacterial isolates from Ranu Pani, Ranu Regulo, Ranu Grati, and Ngebel Lake; also it identifies the isolate with the highest amylase enzyme activity. The amylase enzyme activity test calculates with DNS (Dinitrosalycylic acid) method, molecular identification of the highest bacterial isolate is based on the 16S rRNA gene. Its relationship is determined through the phylogenetic tree with the Neighbor-Joining (NJ) method. The results showed that the fifty-three bacterial isolates have amylase activity about 0.000-0.016 units/mL. The KN bacterial isolate from Ranu Ngebel was the highest amylase activity, producing enzyme around 0.016 units/mL, while isolate G20 from Ranu Grati was the lowest, reaching about 0.0001 Unit/mL. Based on the morphological and molecular identification, the KN bacterial isolate is classified as the Bacillus cereus group with 99.4-100% sequence similarity, closely related to Bacillus paramycoides (NR 157734.1).

Abstract. Yulianti F, Adiredjo AL, Soetopo L, Ashari S. 2020. Short Communication: Morphology and genetic characteristics of potential citrus rootstock in Indonesia. Biodiversitas 21: 5514-5520. Study on variability among the citrus rootstock genotypes is very important to classify and utilize citrus germplasm resources. The genetic variability would greatly assist the breeders in genotypes identification to develop database and maintain the germplasm repositories in Indonesia. It would also be helpful for stakeholders to choose the right rootstock. The aim of the study was to identify the morphology and genetic variability among three potential citrus rootstocks in Indonesia. Morphological and molecular techniques were used to characterize three citrus rootstocks potential in Indonesia. Characteristics of plant, leaves, flowers, fruits, seeds, and genomic DNA polymorphisms were used to characterize three potential citrus rootstocks (Japansche citroen (JC), Citrumelo and Kanci).  Morphological characterizations were based on Descriptors for Citrus (IPGRI 1999). Genetic variabilities were conducted using seven specific markers for biotic and abiotic stresses (VP, CMA, PIP1a, PIP1b, PIP2, osmotin, and Y65). The important characters of citrus rootstock for growers were tree shape, tree growth habit, number of seed, seed polyembryony, and tolerance to biotic and abiotic stresses. JC has spheroid tree shape with spreading growth habit, while Citrumelo and Kanci have ellipsoid tree shape with erect growth habit. These characters may influence scion vigor and size. All of rootstocks observed have high number of seed and polyembryony. These rootstocks amplified PIPs and osmotin markers and could not amplify VP, CMA, and Y65 marker. These plants thought to have the characteristic of tolerance to drought stress with formation of aquaporin and osmotin but susceptible to salinity and Citrus tristeza virus.

Abstract. Mardina V, Harmawan T, Fitriani, Sufriadi E, Febriani, Yusof F. 2020. Euthynnus affinis viscera-an alternative source for protease and lipase enzymes: Characteristic and potential application as destainer agent. Biodiversitas 21: 5858-5864. This study described the characterization of protease and lipase, extracted from the viscera of Euthynnus affinis and their applications as stains removal. Enzyme increased a few folds (3.99 folds for protease and 2.45 folds for lipase) after the submission to partial purification processes by ammonium sulfate precipitation and dialysis. Molecular mass assessment by SDS-PAGE showed that the enzyme solution contains three protein bands, estimated at 70, 42, and 24 kDa for protease and 32 kDa for lipase. Zymography confirmed the presence of protease and lipase in the sample. The protease and lipase exhibited optimum activities at pH 7.0 and pH 8.0 respectively, active at temperatures from 35 to 75oC with optimal activities at 65oC for both. The enzymes were stable at alkaline pH after 90 minutes (mins) of incubation and were also stable up to 65oC, showing the remaining activities of more than 70%. Samples containing protease and lipase as de-staining agents were tested by their ability to remove blood and palm oil stains, with results proving they were effective. Overall, the study showed that crude fish visceral extract contains protease and lipase and is useful in removing household stains, and could substitute for commercial detergents.

Abstract. Ekowati N, Mumpuni A, Muljowati JS, Ratnaningtyas NI, Maharning AR. 2021. Genetic diversity of Pleurotus ostreatus (Jacq.) P. Kumm. strains in Java based on Random Amplified Polymorphic DNA markers.  Biodiversitas 22: 3488-3493. Genetic variation in a fungal population can occur due to mutation and recombination, resulting in changes in the nucleotides that encode specific DNA sequences. Strains with a high genetic distance and good production capabilities can be used to develop genetic breeding. This study aimed to investigate genetic relationship among Pleurotus ostreatus strains cultivated in Java (Bogor, Cianjur, Tasikmalaya, Purwokerto, Yogyakarta, Tawangmangu, Malang, and Madiun) based on random amplified polymorphic DNA (RAPD) markers.  The research method consisted of DNA isolation and DNA amplification using six primers, i.e. OPA2, OPA3, OPA4, OPA7, OPA9, and OPA10. DNA band data were analyzed using NTSYSpc21 software to determine the level of genetic similarity, based on the Unweighted Pair Group Method with Arithmetic Average Algorithm (UPGMA). In all, 101 amplified DNA bands were obtained, with sizes ranging from 136 to 2320 bp and 96.0% of the bands were polymorphic. Based on cluster analysis, it shows that three clusters were formed. There were genetic variations and relationships among eight P. ostreatus strains in Java with a genetic similarity varying from 37-98%.

Abstract. Isnaini Y, Praptosuwiryo TNg. 2020. In vitro spore germination and early gametophyte development of Cibotium barometz (L.) J. Sm. in different media. Biodiversitas 21: 5373-5381. Cibotium barometz (L.) J. Sm. is known as the golden chicken fern and included in Appendix II of CITES. It is an important export commodity for traditional and modern medicine. Globally, populations of this species are under significant pressure due to overexploitation in the wild. In vitro culture is one of the technologies used for ex-situ propagation and conservation of rare and endangered ferns and lycophytes. This study’s objectives were: (i) to observe in vitro spore germination and early gametophyte development of C. barometz, and (ii) to determine the best culture medium for rapid spore germination and early development of the gametophytes. The sterilized spores were sown in half-strength Murashige & Skoog (½MS) basal medium supplemented with combinations of 6-Benzylaminopurine (BAP) and ?-Naphthalene acetic acid (NAA). A factorial combination of four BAP concentrations (0, 2, 4, and 6 mg L-1) with four concentrations of NAA (0; 0.01; 0.03 and 0.05 mg L-1) created 16 treatments replicated in a Completely Randomized Design. Spore germination of C. barometz was observed to be Vittaria-type, and its prothallial development was Drynaria-type. Spore germination started 7-14 days after sowing. Young heart-shape gametophytes consisting of 110-240 cells were formed in 45-61 days after sowing. The two best spore culture media for rapid spore germination and development of C. barometz gametophytes were ½ MS with or without 2 mg L-1 BAP.

Abstract. Malan DF, Litta AL, Kougbo MD, Diop AL, Kouassi KG. 2020. Wild edible plants in four Agni tribes of Central-east and Northeast of Côte d’Ivoire: a comparative study. Biodiversitas 21: 4896-4902. An ethnobotany survey was carried out in twelve villages of the four Agni tribes from the Center-east to Northeast of the Côte d'Ivoire, in order to assess the evolution of the knowledge and know-how of these peoples concerning wild edible plants. Frequency of citations and the Smith index of each of edible plants were obtained with data from the survey of 571 informants (279 men and 292 women). Factorial analysis of the correspondences was also performed in order to reveal the similarities between the different tribes. In total, 77 plant species (36 families and 67 genera) were cited as consumed by humans. The most used parts are the fruits (65.38%), and leaves (24.36%). Analysis of the similarities shows that only 18.82% of these species are common to the four tribes. In addition, knowledge related to wild edible plants is gradually degrading, for several reasons, including obsolescence of use and the unavailability of plants due to environmental degradation. Thus, the valuation and protection of these resources would be beneficial to populations.

Abstract

The proboscis monkey (Nasalis larvatus) is an endemic species to Borneos’ island and is largely confined to mangrove, riverine, and swamp forest. Most of their habitat is outside the conservation due to degraded and habitat converted. Habitat loss is a significant threat to a decreased in the monkey's population. Berau Delta is an unprotected habitat of proboscis monkey, lacking in attention and experiencing a lot of disturbances. This study was conducted on April – August 2019; with aims of the study is to determine Species Distribution Modeling (SDM) for identifying proboscis monkey habitat suitability in Delta Berau, East Kalimantan. The MaxEnt algorithm was used to produce a habitat suitability map based on this species’ occurrence records and environmental predictors. We built the models using 208 points of proboscis monkey presence and 12 environment variables within the study area. Model performance was assessed by examining the area under the curve. The variables most influencing the habitat suitability model were the riverine habitat (60.9%), distance from the pond (16.0%), and distance from the coastline (5.2%). The proboscis monkey suitable habitat is only 9.32% (8,726.58 ha) from 93,631.41 ha total area. The appropriate habitat areas are Sapinang Island, Bungkung Island, Sambuayan Island, Saodang Kecil Island, Besing Island, Lati River, Bebanir Lama, Batu-Batu, and Semanting Bay. We provide some suggestions for the proboscis monkey conservation, which are local protection of uninhabited islands, participatory ecotourism management, and company involvement in protection and management efforts.
