Biodiversitas 24: 3630-3640. The impact from the use of diclofenac on the Indian subcontinent is the main reason why the Himalayan vulture Gyps himalayensis Hume, 1869 has near-threatened conservation status. In particular, it has ecological niches different from those of other vultures in the same genus; however, there has been no systematic study on genetic diversity. This study analyzed the genetic diversity of Himalayan vultures that had migrated to Thailand during the winter in conjunction with samples from a limited GenBank database. The results identified no evidence of Himalayan vulture genetic diversity loss after Gyps vultures were affected by diclofenac since the 1990s and the values were related to raptors with stable population status, which may be the result of ecological niche. Genetic differences or group divided were found in the mitochondrial DNA (mtDNA) Control Region (CR) and Cyt b+CR except in Cytochrome b (Cyt b). The group division based on the results of genetic distance between CR and Cyt b+CR shows that the genetic distance between groups of CR was 10-12 times greater than that of Cyt b (0.771±0.055-0.923±0.084 and 0.076±0.068, respectively) and the difference was also present when analyzed with the combined data set of Cyt b+CR (0.448±0.036). This is an important indicator for the possible study of population structure through phylogeography, because the Cyt b from other studies did not indicate any genetic differences between populations of Himalayan vulture and other Gyps vultures, which may update conservation proposals to be more accurate and effective.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"688 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78696338","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: 3471-3480. Mangroves play a crucial role in supporting intertidal flats and providing habitats that enrich benthic communities, which in turn serve as feeding grounds for coastal waterbirds. However, the degradation of mangrove habitats caused by coastal reclamation activities indirectly impacts prey availability and, consequently, the populations of waterbirds. The coastline habitat along the Important Bird and Biodiversity Area (IBA) of the South West Johor Coast is currently under threat due to new and ongoing development projects involving large-scale reclamation activities. Therefore, this research was conducted to study the diversity and abundance of waterbirds and their relationship with prey availability. The study was conducted in three coastal mudflat sites along the South West Johor Coast, namely Tanjung Piai, Pontian Kechil, and Muar, from November 2020 to May 2021. The direct observation technique was used to determine the abundance of waterbirds, while the benthic core sampling method was employed to assess prey availability in all study sites. In total, 3,717 individual waterbirds, comprising 17 species, were counted across the three study sites. The study confirmed a significant positive relationship between the abundance of waterbirds and prey availability (R2=0.501). The results of this study serve as important baseline data and references for the conservation of waterbirds along the South West Johor Coast. Through the study, we believe that the relevant authorities are able to formulate sound conservation strategies to preserve the habitat for a vast diversity of waterbirds.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86918976","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}

Anatomical, morphological and physiological leaf characters of black betel (Piper betleL. var. nigra) in varying natural and man-made habitats. Biodiversitas 24: 3236-3244. Piper betle L. var. nigra or black betel (known as Sirih hitam in Indonesia) contains valuable secondary metabolites, such as alkaloids, flavonoids, saponins, tannins, phenols, carotenoids, steroids and terpenoids. Black betel leaf extract has been shown to have antimicrobial activity thus there is a prospect to be developed as a promising herbal plant. Nevertheless, little information is available about its development as a medicinal plant. This research studies the influence of different habitats on several characters of black betel leaves with the aim to understand the suitable environmental conditions for the optimum growth of black betel plants. We used a survey method and random sampling of black betel leaves in four locations in Java Island, Indonesia, namely Banyuwangi which represents natural habitat, and Karanganyar, Ngaglik and Pakem which represent man-made habitats. Measurements of temperature, humidity, soil moisture and light intensity were carried out at each location. Analyses of leaf area, leaf water content, total leaf chlorophyll content and flavonoid content were undertaken and statistically analyzed using SPSS software. Leaf transverse sections were also observed. The results showed that the environmental parameters differed in the four locations. Leaves samples from the natural habitat in Banyuwangi were significantly different (P<0.05) from the three man-made habitats for chlorophyll and flavonoid content. For water content, significant difference was only for Banyuwangi samples with those from Karanganyar and Pakem. For leaf area, significant difference was only found between the Banyuwangi samples and Karanganyar. Observations on the transverse cross section of midrib of black betel leaves from the four locations showed structures that are generally found in Piper betle species, namely the presence of an epidermal layer, trichomes in the abaxial part of the leaf, several layers of the hypodermis, visible vascular tissue and the presence of secretion cells. There were several differences in the leaf anatomy such as greater number of trichomes on the leaves from Karanganyar, the secretory cells that were more visible in the leaves from Ngaglik and Banyuwangi and the sclerenchymal tissue that was more visible in the leaves from Banyuwangi. Such differences are likely influenced by variations in environmental parameters thus showing that the man-made habitat in the Karanganyar location can affect leaves characters similar to black betel plant grown in its natural habitat in Banyuwangi.\u0000","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78639160","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 bigeye thresher shark Alopias superciliosus (Lowe, 1841) is a highly migratory marine shark, widely distributed globally in tropical and temperate seas. The bigeye thresher shark is listed as a Vulnerable/VU species on the red list of the International Union for Conservation of Nature (IUCN) and listed on Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Genetics is a substantial essential approach to conservation, management, and sustainability. This study investigates the bigeye thresher shark’s genetic diversity and structure populations A. superciliosus that landed in Palabuhanratu Fishing Port, Sukabumi, West Java, Indonesia. Samples were collected in Palabuhanratu (n=16) and secondary data from the Atlantic Ocean (n=212) and Indian Ocean (n=16) sequences were obtained from GenBank. A total of 16 sequences of A. superciliosus have been amplified using mitochondrial DNA control region (dloop) with 857 bp in size sequenced. The Genetic diversity result showed haplotype diversity value in Palabuhanratu (Hd=0.86667; ?=0.01048) considered a high value. Overall, AMOVA and FST results showed significant differences in population structure between Palabuhanratu, Atlantic, and Indian Ocean with an FST value of 0.04420 (p-value <0.05).

Etlingera elatior (Jack) R.M.Sm. has been well-documented to have antioxidant and antidiabetic properties. Among all medical conditions worldwide, diabetes mellitus is one of the leading causes of death. Therefore, research on the discovery of antidiabetic medicines inhibitory to ?-glucosidase (an enzyme for degrading complex dietary carbohydrates into sugar in the digestive process) is urgently needed. This study aims to isolate and evaluate the potential of the fermentation culture of endophytic fungi associated with E. elatior to inhibit the activity of ?-glucosidase. The endophytic fungi were isolated from various parts of E. elatior. A total of 29 isolates were successfully isolated from the plant's roots, stems, leaves, and flowers. The endophytic fungi were tested for their ability to inhibit ?-glucosidase activity in bioassays. Among those isolates, 8 were inhibitory to such an enzyme, and 2 showed the highest inhibitory activities. Morphotype and molecular identification of those isolates, using their Internal Transcribed Spacer (ITS) regions of ribosomal DNA (rDNA), identified them as Daldinia eschscholtzii isolate CFL 7 and Hypoxylon trugodes voucher YMJ 57, with IC50 values of 738 µg/mL and 825 µg/mL, respectively.

Sustainable economic analysis and length weight relationship of Bullet Tuna (Auxis rochei) fishery in east area of Bali Strait, Indonesia. Biodiversitas 24: 3528-3535. Bullet tuna (Auxis rochei) is a small pelagic fish with an important economic value and is mainly caught by fishermen in the east area of Bali Strait, Indonesia. The high market demand for this fish has increased fishing efforts to achieve maximum catch, and this uncontrolled fishing activity will threaten its sustainability and economic potential. This study was conducted to determine stock status both biologically and economically. The length-weight relationship was calculated by measuring the length and weight of 1,200 samples of fish landed in the Pengambengan Archipelago Fishing Port (AFP) in Jembrana Bali Province from February to March 2020. The calculation of maximum sustainable yield (MSY), maximum economic yield (MEY), and equilibrium of open access (OA) were done by using secondary catch data from 2008 to 2019. Gordon Schaefer’s model analysis found that the values of YMSY and fMSY were 3,314 tonnes year-1 and 3,503 trips year-1, respectively. While the values of YMEY and fMEY were 3,160 tonnes year-1 and 2,750 trips year-1, respectively, which gave a maximum profit of about 1.4 billion USD year-1. In addition, the equilibrium of OA would be achieved when the fishing effort reaches 5,500 trips year-1 and the amount of catch reaches 2,237 tons year-1. The growth pattern of the bullet tuna was isometric, which indicates that the bullet tuna in the east area of Bali Strait has a proportional body shape. The utilization status of bullet tuna (A. rochei) is over-exploited.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83874944","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}

Surface ultrastructure of tick (Acari: Ixodidae) on Moa buffalo from Southwest Maluku District, Indonesia. Biodiversitas 24: 3230-3235. Moa buffalo is one of the local Indonesian buffalo families in the Southwest Maluku District with very limited distribution and is found only on Moa Island. It exhibits distinct characteristics that distinguish it from clumps of mud buffalo and other local breeds, making it a valuable local livestock resource in Indonesia. Meanwhile, ticks are obligatory hematophagous ectoparasites with direct effects on the host, such as blood and weight loss, and their indirect effects are more associated with their role as vectors of disease-carrying pathogens. This study aimed to identify ticks infesting Moa buffalo by analyzing their surface ultrastructure using a Scanning Electron Microscope (SEM) method. This method enabled the establishment of the taxonomic status to obtain comprehensive data regarding the mapping of tick species in Moa buffalo. The samples were manually collected, and the body of the cattle was divided into four regions to determine the preferred attachment sites of ticks. The head, back, tail, and legs were all carefully examined, and each tick was carefully picked from the surface using tweezers or a pair of thumb forceps. Furthermore, the tick samples were collected from three different parts of the Moa buffalo's body, namely the armpit, inguinal region, and perianal area. Based on observations of morphological characters, the ticks found in Moa buffalo were of two species, namely Dermacentor auratus Supino, 1897 and Haemaphysalis bispinosa Neumann, 1897. The Dermacentor genus, specifically D. auratus exhibited specific morphological characteristics, including a pair of eyes located at the coxae II level, an ornate scutum, capitulum, and feet, as well as a short hypostome with 3:3 tooth arrangement. Members of this genus also had festoons, with the size of coxae increasing from I to IV. On the other hand, H. bispinosa was characterized by underdeveloped cornua. The segments of palpal III, for both males and females exhibited posterodorsal and posteroventral protrusions. The posteroventral segment of palpal III formed a wide and blunt triangle in both sexes, while the palpal III section had wide median spurs. These characteristics were keys for the identification of H. bispinosa species.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"142 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74021917","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}

Termite diversity and abundance based on altitude in Mount Ungaran, Central Java, Indonesia. Biodiversitas 24: 3332-3337. Termites are social insects whose main diet is the cellulose and lignocellulose found in rotting wood and in some fungi. As the Mount Ungaran area in Central Java, Indonesia, has been converted to agriculture and other purposes, termite habitat has become increasingly narrow, with a reduction in the insects’ food sources. The purpose of this study was to analyze the species of termites found on Mount Ungaran and the factors that influence their lives. In addition, the differences in species according to slope (north, south, east, and west) and altitude were assessed. This research was conducted in three stages: termite collection, termite identification, and data analysis. The main species found in this study were Coptotermes curvignathus Holmgren, 1913, Odontotermes javanicus Holmgren, 1912, Macrotermes gilvus Hagen, 1858, Nasutitermes matangensis Haviland, 1898, and Bulbitermes constrictiformis Holmgren, 1914. Based on a Shannon-Wiener analysis, the west slope had the highest diversity index, which was primarily influenced by four environmental factors (soil pH, soil temperature, soil moisture, and rainfall). In the canonical relationship correspondence analysis, soil pH, light intensity, and canopy cover were the environmental factors that most affected the diversity and abundance of termites on Mount Ungaran. The conclusions that can be drawn from this study are that termite richness varied between slopes and the environmental factors that were the most associated with the variation were soil pH, light intensity, and canopy cover.\u0000","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80231460","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}

Weeds interference in rubber farmland may reduce latex yield. Farmers apply herbicides to control weeds. However, the herbicide not only controls weed but also affects the presence of soil macrofauna. A study has been conducted to determine the effect of different method of weed control on soil macrofauna and weeds at smallholder rubber farming at Pulau Punjung, Dharmasraya District, West Sumatra, Indonesia. The experiment was conducted in a completely randomized block design with 6 treatments and 4 pseudo-replications. Treatment was mechanical control, without weed control, and 4 doses of herbicide glyphosate+metsulfuron-methyl (1.5 L ha-1 + 15 g ha-1, 2 L ha-1 + 15 g ha-1, 2.5 L ha-1 + 15 g ha-1, 3 L ha-1 + 15 g ha-1) with 400 L ha-1 of volume. Pitfall traps were used to collect the soil macrofauna. Data were analysis with ANOVA for weed and soil macrofauna in response to different methods of weed control. Results demonstrated that the application of glyphosate+metsulfuron-methyl herbicide significantly suppressed weeds higher than that of other methods of weed control (p<0.05). Para grass (Brachiaria mutica (Forssk.) Stapf) was the most dominant weed but has been affected most by 3 L ha-1 + 15 g ha-1 herbicide mixture. Soil macrofauna of the order Hemiptera was affected most by the application of herbicide with a total reduction of 71.58% of number of individuals at 12 weeks after application of herbicide.
