High-throughput analysis using 16S rRNA gene of bacterial communities present in selected bivalves and gastropods species from Bayug Island, Iligan City, Philippines. Biodiversitas 25: 431-438. Seashells, which include bivalves and gastropods, have global recognition for their significant contributions to the economy, ecology, and medicine. They hold value as a food source and are highly regarded as effective biological indicators. The objective of this study is to identify the bacterial communities present in selected edible species of bivalves (Pinctada margaritifera Linnaeus, 1758 and Anadara granosa Linnaeus, 1758) and gastropods (Canarium urceus Linnaeus, 1758 and Conus stercusmuscarum Linnaeus, 1758), through high-throughput sequencing metabarcoding. Bacterial samples were collected via a swabbing technique on the surface and inside parts of selected mollusc species, which were then placed on sterilized seawater for DNA extraction. Genomic DNA was isolated from the samples, and the V3-V4 region of the 16S rRNA gene was amplified and sequenced using the Illumina MiSeq platform. Four amplicon libraries were generated, representing the two bivalve and two gastropod species in the study area. Data analysis was conducted using the Parallel Meta Suite software. Upon quality control and processing, 173,489 amplicon sequence variants (ASVs) were obtained. Within the bacterial community, the most abundant genera included Stenotrophomonas, Vibrio, Serratia, Photobacterium, and Shewanella. The assessment of alpha diversity, using the Shannon index, indicated a higher diversity in A. granosa. Furthermore, the analysis using the PICRUSt algorithm within the Parallel Meta Suite unveiled the involvement of specific bacteria found in the selected gastropod and bivalve species in various functions. These functions encompass protein production, xenobiotic metabolism, biodegradation, and other metabolism-related processes, supporting these organisms' ecological and physiological roles.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"22 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457713","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}

Putri NP, Muharam MR, Ritonga A, Ruswanti CD, Arthen D, Munasik. 2024. Examining the effectiveness of bored pile coral for coral rehabilitation. Biodiversitas 25: 153-161. Semut Island is located in Kiabu Village, Anambas Islands, Riau, Indonesia, and has suffered significant damage to its coral cover due to blast fishing. To address this issue, Anambas Foundation initiated a coral reef rehabilitation on Semut Island using a customized artificial reef called Bored Pile Coral (BPC), a cylindrical structure made of concrete hammered into the seabed. This research aims to examine the effectiveness of BPC by monitoring its performance. Therefore, from February 2022 to January 2023, 1,500 BPCs were deployed and attached with corals covering an area of 170 m2. We quantified five ecological indicators, i.e., coral cover, survival rate, recruitment, growth rates, and fish biomass. Results showed an increase in coral cover from 3.8% to 8%. The survival rate was 64%, and the mean monthly growth rates varied among three genera: Pocillopora sp. (0.235±0.02 month-1), Acropora sp. (0.22±0.03 month-1) and Porites sp. (0.08±0.02 month-1). The monthly mean fish biomass data showed the biomass was 427,25 Kg/Ha and increased 3,9 times since the beginning of the research. BPC's structure has been proven to act as stable media for hard corals, although the modification may be necessary to enhance structural complexity and suitability for carnivorous fish habitats.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"307 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457537","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}

This study was conducted to identify the cultural activities related to swine rearing in East Flores District and analyze the decision making in choosing the types of rearing practice. Based on the survey using questionnaires from 120 pig farmers, which was conducted purposive, were those who had at least three sows for breeding, fattening with five heads of pigs, and combined with sows and sires. To identify the role of local pigs, as many as 3 informants consist of traditional leaders, farmers, and Agriculture Extension Officers, and analyzed by multinomial logistic regression model. The results showed that the traditional rituals that required the sacrifice of pigs included the ceremonies marking the start of building residential and traditional community buildings and dowry (belis)  presentation in a wedding ceremony. The decision-making in choosing the rearing practice was influenced by pig ownership, care system (P<0.01), and income (P<0.05). Farmers who have small scale will choose extensive and fattening systems to reduce feed costs. Those practicing breeding are still maintaining local breeds because traditional rituals require it. Further efforts are needed to increase the populations of local breeds as well as cross-bred pigs to maintain the ceremonies in traditional rituals and income generation.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"254 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457833","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}

Phytochemical analysis and antioxidant activities ethanol extract of propolis Trigona spp. from different vegetation in Lombok, West Nusa Tenggara, Indonesia. Biodiversitas 25: 404-411. Propolis is a natural substance containing a resin that is collected by honey bees from various plants and has a significant effect on human health such as antibacterial, antifungal, anti-inflammatory, antiviral, anesthetic, antioxidant, antitumoural, antiprotozoal, anticancer, antihypertensive, anticarcinogenic, antihepatotoxic and has cytotoxic activity. Cultivation of Trigona spp. in Lombok is growing rapidly. Trigona spp. produces more propolis than honey bees of Apis spp., but bee products that are maximally utilized are only honey, and propolis has not been utilized optimally. Currently, there is no scientific validation of the phytochemical content, bioactive compounds, and biological activities of ethanol extract propolis Trigona spp. from Lombok, West Nusa Tenggara. So, this study aimed to determine the phytochemical compounds, bioactive compounds, and antioxidant activity of propolis. Gas Chromatography-Mass Spectrometry (GC-MS) analysis was performed to determine the bioactive compounds of ethanol extract propolis. DPPH (2,2-diphenyl-1-picrylhydrazyl) was used to evaluate antioxidant activity. The composition of propolis compounds is different for each propolis depending on the bee species and the vegetation source from which the resin was collected. In this research, propolis was collected from different vegetation sources (cashews, moringa, coffee, and lote trees). This study used qualitative and quantitative phytochemical analysis and the antioxidant DPPH test. Different components and percentages cause significant variations in the results obtained from phytochemical tests. The content is different in various propolis, there are saponins, flavonoids, and tannins. The highest antioxidant activity was found in propolis with moringa resin 38.4150 (very strong), followed by lote tree resin -66.0420 (strong), cashew resin 81.8140 (strong), and coffee resin 100.7465 (moderate).","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"5 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140458943","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}

Mudskippers of genus Boleophthalmus are commonly found in the Indo-Pacific area. This study aimed to examine the diversity of the genus Boleophthalmus from the north coast of East Java Province, Indonesia by employing the mitochondrial COI gene for DNA barcoding and morphological characterization. Ten individuals of this genus were analyzed. According to the similarity percentage evaluated using Basic Local Alignment Search Tool (BLAST) and Barcode of Life Data (BOLD) identification engines, all the individuals were identified as Boleophthalmus boddarti Pallas, 1770. However, phylogenetic analysis revealed that three of the individuals were identified as B. boddarti, and seven were identified as Boleophthalmus pectinirostris Linnaeus, 1758 originated from East Java, which is separated from the clade of B. pectinirostris from East Asia population. These results were supported by the genetic distance of 8.93%-13.81% and the morphological characteristics determined by principal component analysis (PCA). PCA revealed that B. boddarti and B. pectinirostris are primarily distinguished by the number of (longitudinal) scales (69-75 versus 113-123), length of second dorsal fin base (42.3-43.9 versus 38.1-49.0), and caudal fin length (18.1-22.4 versus 17.5-21.6). Further detailed studies are needed to clarify whether the seven individuals belonging to B. pectinirostris complex should be regarded as a new species or a new subspecies.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"11 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140458889","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}

Biodiversity of hydrolytic enzymes-producing soil bacteria from a Durian Park, Jombang, Indonesia: Beneficial prospect for sustainable agriculture. Biodiversitas 25: 392-403. Biofertilizer is an alternative to chemical fertilizer that can enhance plant growth but is specific to certain plants and soils. Various biofertilizers have been produced, but the specific biofertilizers to enhance durian growth have not been widely available. This study aims to determine the potential of hydrolytic enzyme-producing bacteria, one of the microbial components of biofertilizers, in the De Durian Park (DDP) area, Wonosalam, Jombang District, Indonesia. The bacteria were isolated using the selective medium plating technique. The obtained isolates were screened for their ability to produce cellulase, amylase, protease, and lipase. The clear zone around the colony indicated the ability of the isolates to produce hydrolytic enzymes, and then the clear zone index was obtained. The best three isolates for each enzyme production were characterized macroscopically, microscopically, and biochemically, then identified using 16S rRNA gene sequence analysis. Fifty-two isolates were successfully obtained from the soil of DDP. The best three cellulolytic bacteria had indices ranging from 1.83 to 2.14, categorized as moderate-strong, identified as Bacillus anthracis, B. pacificus, and B. cereus. The amylolytic bacteria ranged from 1.25 to 1.35, categorized as moderate, and identified as Bacillus anthracis, B. paranthracis, and B. paramycoides.

Genetic variation of the native Rusa deer (Rusa timorensis) in Java and Bali (Indonesia) as revealed using non-invasive sampling. Biodiversitas 25: 355-360. Rusa deer is a vulnerable species with a large geographic range but natively inhabits Java and Bali. Despite the wide distribution, its native population is declining, raising a concern about a small population's adverse genetic effect. It encourages genetic studies to provide baseline data that has been vacant recently. This research aimed to demonstrate an application of non-invasive sampling to collect DNA samples and a simple procedure to obtain and analyze genetic data for the Rusa deer. This research also aimed to provide genetic variation of the native deer population as baseline data. The research sites were Baluran, Alas Purwo in East Java, and Bali Barat national parks from which fecal samples were collected. Moreover, 20 DNA samples were isolated from the feces using a kit (Dneasy PowerSoil Pro from Qiagen) and amplified at the control region gene using a forward: AAACCAGAAAAGGAGAGCAAC and a reverse: TCATCTAGGCATTTTCAGTGCC primer. The amplicons were sequenced, and the number of Haplotypes (Hn), Haplotype diversity (Hd), nucleotide diversity (p), site polymorphism, and phylogeographic tree were determined. The result showed that all the sequences had coverage of 100% and identity >98% with the Rusa timorensis sequence available in the GenBank. Furthermore, we found Hn = 11, Hd = 0.88, p = 0.005 and 30 site polymorphisms. Therefore, compared to an introduced population, the Rusa deer has a richer Hd and higher site polymorphism but a poorer p. Furthermore, we found that the Baluran population had high Hd, p, and is possibly forming a distinct clade.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"84 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459072","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 phytochemical compounds found in sandalwood plants (Santalum album L.) are recognized for their anti-pathogenic properties, suggesting the potential of sandalwood endophytic fungi as effective anti-phytopathogens. Alternaria solani and Fusarium oxysporum threaten tomato plants, whereas Phytophthora palmivora is particularly detrimental to cocoa plants. The aims of this study were: (i) to obtain isolates of endophytic fungi from roots, stems, and leaves of sandalwood plants and (ii) to assess the ability of endophytic fungi as anti-phytopathogens in vitro. Endophytic fungi were isolated through a direct plating method and next by purification and identification. All obtained endophytic fungi underwent testing for their antagonistic potential against A. solani, F. oxysporum, and P. palmivora in vitro through the dual culture method. The inhibition percentage was analyzed using variance analysis and further examined with the 5% HSD test. The study successfully isolated 104 endophytic fungal isolates from the sandalwood; 29 isolates were from the roots, 33 from the stems, and 42 from the leaves. All endophytic isolates demonstrated the ability to inhibit the growth of A. solani, F. oxysporum, and P. palmivora in vitro, with various inhibition percentages ranging from 26.7 to 83.3%.
