Ethnobotany and conservation applications in the Noken making by the Sougb Tribe of West Papua, Indonesia. Biodiversitas 24: 4577-4583. Documenting local ecological knowledge is critical for understanding complex ecological-cultural interactions to protect indigenous community entities. Woven baskets known as Noken have been part of Papuan indigenous culture for centuries, yet ethnobotanical aspects of Noken making remain poorly understood. Hence, this study describes Noken-making from an ethnobotanical perspective. We acquired ethnoecological knowledge by interviewing respondents who were actively involved in the production of Noken. The results revealed that the Sougb Tribe (from South Manokwari District, West Papua, Indonesia) utilized pineapple as a primary material for weaving and other natural materials as dyes, with this process undertaken mainly by women. We also document the Sougb Tribe's adaptation and continuous interaction with their dynamic environment that has evolved during Noken's making. Moreover, the recommendation to conserve Noken preserves biocultural diversity and habitats for key plant species. Since Noken has played an essential part in shaping the Sougb Tribe's cultural identity, conserving the use of Noken will aid in preserving the habitats of plants used as materials for Noken. In the future, the provincial government should assist habitat biocultural conservation by granting tribes customary forest status to facilitate plant habitat protection in line with the sustainable development agenda of West Papua Province.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135303367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis Mycobacterium lepromatosis as the causative agent of diffuse lepromatous leprosy patient in Indonesia. Biodiversitas 24: 4521-4529. The present investigation deals with identifying, besides clinical signs, both microscopically and molecularly, to clearly differentiate the Mycobacterium lepromatosis genome against Mycobacterium leprae so that treatment can be carried out properly. To date, there has yet to be a report on this discovery in Indonesia. A 53-year-old Javanese man had ulceration on both legs that had been reoccurring in the past two years. Some of the ulcers were preceded by blisters that rapidly turned into a wound. The ulcers were described as wide and deep, covered with blackish crusts and some exudative areas with irregular edges. He had a history of recurrent epistaxis and had never been treated for leprosy. There was rapid progression and the development of new ulcers on his legs and hands for two weeks before hospitalization. There was body weakness, no fever, and the skin was shiny and ichthyosiform. On the face, diffuse infiltration will appear without nodules, and madarosis also occurs. Examination in this study used the BTA examination method, histopathological examination with HE and Wade-fite staining with biopsy material and the PCR method using skin slit smear material. The results of the BTA examination showed that BI was 3+, and MI showed 7%. Histopathology showed thinning of the epidermis with many foam cells containing BTA, including endnotes and perivascular tissues. Nested PCR examination with LERF2-MLER4 primers for detecting M. leprae showed a positive result with amplicon 135bp in size. Advanced PCR examination using LPMF2-MLER4 primers for detecting M. lepromatosis also showed a positive result with amplicons 142bp in size. The result of DNA sequencing was consistent with the order of nucleotides of M. lepromatosis. Based on the clinical and histopathological results, it was consistent with diffuse lepromatous leprosy and Lucio’s phenomenon. The DNA sequencing showed a suitable result with M. lepromatosis, which has been reported in Mexico. Thus, it can be concluded that in biomolecular strain, this bacterium is an M. lepromatosis that has never been reported in Indonesia.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135485902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Javan deer (Rusa timorensis Blainville, 1822) is a protected wild animal with high potential economic value; captive breeding can be done to avoid extinction and sustainably utilize it. Most land ownership by rural communities in Indonesia is less than 5 ha; therefore, it is essential to design small-scale captive breeding, which local people can adopt to meet economic isxadwnterests and species conservation. We assessed a site part of the Perum Perhutani area in East Java dedicated to developing captive breeding models. Assessment is an essential consideration in exploring location feasibility and designing optimal allocation of available space; data collection on bio-physical conditions used nested sampling, circular plots, and profile diagrams. Feed availability is obtained by identifying the grass type and calculating its productivity. The collected data were then analyzed and compared with the needs of the Javan deer. The selected location was then made a captive design for space allocation based on the management and basic needs of the Javan deer. The results showed that the location at RPH (Resort Pemangkuan Hutan=Forest Management Resorts) Malo (Bojonegoro District, East Java, Indonesia) could be declared feasible to be developed as a Javan deer breeding area. The captive site design is mini ranching; this captive design consists of the breeding/management and office blocks.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135485899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diversity and spatial distribution of Order Diptera from Kuala Keniam National Park, Pahang, Malaysia. Biodiversitas 24: 4668-4674. A study on the diversity and distribution of order Diptera was conducted in different Kuala Keniam National Park, Malaysia landscapes. Three malaise traps were placed in three landscapes: the forest fringe, middle forest, and inner forest. A total of 1920 Diptera were recorded from 19 families and 109 morphospecies of order Diptera. Anthomyiidae, Calliphoridae, Pipunculidae, Scenopinidae, Ulidiidae, Tephritidae, Ceratopogonidae, Stratiomyidae, Asilidae, Syrphidae, Tipulidae, Ephydridae, Cecidomyiidae, Dolichopodidae, Phoridae, Culicidae, Muscidae, Sciaridae, and Drosophilidae were the identified families. The family with the highest number of individuals collected was Phoridae, with 89 individuals (5 morphospecies) collected from the forest fringe, followed by 271 individuals (6 morphospecies) from the middle forest and 697 individuals from the inner forest (7 morphospecies). Pipunculidae had the least collected individuals, with only one in the inner forest. The forest fringe recorded the highest Shannon-Wiener Diversity Index (2.13), followed by the middle forest (1.68) and the inner forest (1.04). The forest fringe also recorded the highest Evenness Index and Margalef Richness Index with 0.44 and 3.16, respectively. The distribution of Diptera differed significantly along the environment gradients from the forest fringe to the inner forest (p<0.05), and the pairwise comparison showed that the difference comes from Trap 2 and Trap 3 (p<0.001). The forest fringe was more diversified than the middle and the inner forest, even though the number of individuals was low. Vegetation types and sunlight might be the reasons behind this discovery. The results from this study can be used as baseline data for future reference on the diversity of Diptera from the forest reserve.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135486126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morphological and molecular characteristics of the species Cosmocerca commutata and C. ornata (Nematoda: Cosmocercidae) in Uzbekistan. Biodiversitas 24: 4609-4616. In studies on the helminth fauna of amphibians conducted by numerous researchers, two species of the genus Cosmocerca, namely Cosmocerca ornata (Dujardin, 1845) Diesing, 1861 and C. commutata (Diesing, 1851), have emerged as the most common and extensively studied. This paper elucidates the morphology and molecular characteristics of two nematode species, Cosmocerca commutata and C. ornata, found in the intestines of Pelophylax sp. and Bufotes pewzowi in the Ferghana Valley of Uzbekistan. The captured amphibians were individually kept in plastic bags with water and vegetation until the examination. It is the first record of B. pewzowi as a host for both species C. commutata and C. ornata. Standard methods were used for the fixation and processing of nematodes. These nematodes ?orphologically differ in body size, relative length of spicules and gubernaculum (C. commutata has twice the length of gubernaculum and spicules compared to C. ornata), shape and number of plectanes (C. commutata has 8 pairs of plectans and 4 pairs of caudal papillae, while C. ornata has 5 pairs of plectanes and 3 pairs of caudal papillae), and tail morphology and length. The morphological evidence supports that C. commutata and C. ornata commonly parasitize anurans in Uzbekistan. This study provides molecular data of both species and their sequences differed by 1.5% (6 bp) in the ITS1+5.8S+ITS2 region. Each species of them formed a well-supported clade in the phylogenetic tree. Our findings contribute to the comprehension of species and genetic diversity of the genus Cosmocerca in Uzbekistan.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135486127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abdi AM. 2023. Applying culturomics to understand the motives behind the surrender of pet gibbons: Evidence from Indonesia. Biodiversitas 24: 4606-4616. Seven of nine gibbon (Hylobatidae) species in Indonesia are protected by national regulation with threats to habitat fragmentation and illegal trade. People persist in owning gibbons as pet animals, violating the protected species law. To date, numerous pet gibbons have been surrendered to the authorities, which could result from intensified public awareness. More targeted demand reduction campaigns may be possible with a better understanding of the motivations behind these handovers. This study aims to document gibbon surrenders by the public to authorities and the motives behind these actions. Instagram posts and online local news were collated and analyzed between 2016 and 2023, comprising information on gibbon handovers to the authorities. From the 138 posts analyzed, 161 gibbon individuals, including 6 species from Sumatra (47.2%), Kalimantan (29.8%), Java (21.7%), and Bali (1.2%) were surrendered. Since 2016, the annual number of gibbons received by authorities has steadily increased. Handover motives appear to be overwhelmingly based on legal reasons. Although regarded as ineffective in mitigating trade, law enforcement and fear of the law were the primary reasons for gibbon handovers. Therefore, publicizing successful law enforcement cases of gibbon trade in the media could deter future buyers and reduce demand.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134971732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biodiversitas 24: 4584-4589. Blumea balsamifera L. has long been used as traditional medicine by communities in Aceh, Indonesia and from various parts of the world. For generations, this plant has been believed to have properties to cure various diseases. The results of the GCMS analysis of B. balsamifera leaf from Aceh-Indonesia in the previous study contain various compounds for wound healing, including borneol, jasmoline, camphor, and caryophyllene. The present study aimed to analyze the antibacterial activity of B. balsamifera leaves from Aceh. The sample was taken from the village of Gunongpulo, South Aceh-Indonesia, and the extraction process was carried out using three different types of solvents: ethanol, ethyl acetate, and n-hexane. Three variations of the extract obtained were then tested for antibacterial against Staphylococcus aureus and Pseudomonas aeruginosa by analyzing the inhibitory of each extract. The results showed that the inhibition zone formed on S. aureus against ethanol extract was 2.4 mm, ethyl extract was 9.2 mm, and n-hexane extract was 2.3 mm. In comparison, the inhibition zone formed on P. aeruginosa against ethanol extract was 0 mm, ethyl extract was 9 mm, and n-hexane extract was 4.9 mm. Conclusion: B. balsamifera leaf extract from Aceh contains antibacterial, with the highest inhibition against S. aureus at 9.2 mm and Pseudomonas at 9.0 mm. It is recommended that in the process of extracting B. balsamifera leaves by maceration, the best solvent used is ethyl acetate.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135786542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morpho-physiological and gene expression of East Timor’s local rice plant (Oryza sativa) response to drought and salinity stress. Biodiversitas 24: 4548-4556. East Timor is rich in local rice varieties, such as Silaun, Ime Buci, Me Klan, Me Likan, Me Meak, Me Taek, and Umak Klete. These varieties are tolerant to drought and salinity stress. These superior characteristics emerge as the coping strategy of the rice plants toward environmental conditions such as mountainous, upland planting areas without irrigation networks and coastal regions with high salinity levels. This study determined the tolerance response of East Timor's local rice to drought and salinity stresses. This study was designed in a Completely Randomized Design (CRD) with two factors. The first factor, i.e., rice varieties, consisted of 8 varieties, i.e., Silaun (V1), Ime Buci (V2), Me Klan (V3), Me Likan (V4), Me Meak (V5), Me Taek (V6), Umak Klete (V7), and IR-64 (V8) and the second factor was the abiotic stress treatments, namely no treatment or control (P0), 10% PEG treatment (P1), and 150 mM NaCl treatment (P2). The parameters observed were morpho-physiology and biochemical characteristics of the plants. The results showed that the Silaun local rice variety from East Timor was tolerant to drought and salinity, supported by the gene expressions for tolerance to drought and salinity stress.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135786708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biodiversitas 24: 4427-4437. The waters of Merauke District, located in the Arafura Sea area, have relatively hight penaeid resource, but prawn fishing productivity is the lowest of 11th other Indonesian fisheries management areas.. The optimization of the fishery resource utilization remains poor after the moratorium on fishing vessel licensing in 2014, which is only 11%. Hence, a study is needed to determine the resources’ distribution, abundance, and sustainability. This research aims to analyze the density distribution of banana prawn (Penaeus merguensis De Man, 1888) based on the habitat type, each location separated by ~4-5 kilometers within the coastal ecosystem waters of Merauke District. The research was carried out from March to August 2022. Data were collected within each habitat: the catch, prawn fishing equipment, and oceanographic parameters, and then analyses were undertaken using statistical tests. The results showed that the highest density of banana prawn was obtained in shallow waters adjacent to the mangrove habitat at Bokem (32.68 kg/km2) and Yobar (20.27 kg/km2). In waters adjacent to the sandy beach at Payum (17.98 kg/km2), the density was higher than within the estuarine habitat of Maro River (14.60 kg/km2) and adjacent to the sandy beach at Lampu Satu (14.39 kg/km2). This is due to the influx of fresh water in estuarial habitat, sandy beaches in Lampu Satu and Payum, and mangroves in Yobar, resulting in prawn emigration to areas with higher salinity in Bokem mangroves. It is also thought to be associated with increasing turbidity with a similar pattern in salinity and affecting the density of banana prawns.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135786973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
