Abstract. Hadj Moussa AH, Benaliouche F, Sbartai I, Sbartai H. 2023. Biological activities and chemical characterization of Lavandula angustifolia essential oil from Seraïdi, Northeastern Algeria. Biodiversitas 24: 4535-4543. The objectives of this study are to examine the chemical composition of essential oil (EO) extracted by hydrodistillation from the flowering tops of dry lavender (Lavandula angustifolia) harvested in the town of Seraïdi in Northeastern Algeria and evaluate its antifungal, antibacterial, and antioxidant potential. The chemical analysis of this essential oil was carried out by gas chromatography coupled with mass spectrophotometry (GC-MS). The antimicrobial activity was evaluated by dilution method in solid and liquid medium, and the antioxidant activity was carried out using the DPPH° radical scavenging assay. It revealed the presence of 20 compounds representing the general component of this oil with a yield of 1.71%. This oil is composed mainly of Linalool (31.27%), followed by Camphor (16.21%), Linalool Oxide (11.98%), and Linalyl Acetate (11.93%). Other constituents were identified at relatively medium [2-Furarmethanol (7.49%), 1,8-Cineole/eucalyptol (6.76%), Borneol (5.34%)] and low contents [1-Hexyl butyrate (1.25%)]. The minimum inhibitory concentration (MIC) and the minimum fungicidal concentration (MFC) of lavender EO against Fusarium roseum were 3000 µg/mL and 4000 µg/mL, respectively. Lavender OE had moderate antibacterial activity against Pseudomonas savastanoi. The antioxidant activity of lavender EO was lower than that of vitamin C.

Abstract. Wiryono, Kristiansen P, Bruyn LLD, Saprinurdin, Nurliana S. 2023. Ecosystem services provided by agroforestry home gardens in Bengkulu, Indonesia: Smallholder utilization, biodiversity conservation, and carbon storage. Biodiversitas 24: 2657-2665. Agroforestry system provides ecosystem services such as conserving biodiversity and providing smallholder farmers with food and other daily needs. It can also generate income for the owners. This study was conducted in 105 home gardens of four villages in Bengkulu Province, Indonesia, to analyze tree species diversity and composition, uses, and potential carbon storage in the agroforestry system of home gardens. Tree data were collected on individual trees from 200 plots (10×10 m). Home garden owners were interviewed on the uses of each tree species. The species richness of trees in each village ranged from 18 to 36, with a total of 57 species (29 introduced and 28 native) for four villages. Most trees (30 species) provided food. The above-ground carbon storage of trees ranged from 29 Mg ha-1to 127 Mg ha-1, with an average of 87 Mg ha-1. This study found that the agroforestry system in home gardens serves some ecosystem services, i.e., providing food, medicines, and other daily needs, conserving plant species and the habitat they provide, and storing carbon. These ecosystem services help villagers build resilience to changing environmental and socio-economic conditions.

Abstract. Nguyen TP, La HTG, Do TK, Tran DG. 2023. Polymorphic analysis of theOsHKT1;5exon 1 gene region on seasonal rice varieties with salt tolerant capacity. Biodiversitas 24: 4159-4165. In recent years, saline intrusion has caused serious damage to agricultural production in the Mekong Delta; therefore, research on salinity-tolerant rice varieties is necessary. This study was carried out to screen the salt tolerance capacity of 38 seasonal rice varieties in four concentrations of NaCl supplements, including 4‰, 6‰, 8‰, and 10‰ in comparison with IR28 and Pokkali checks according to IRRI (2021) methods. Eight rice cultivars in four levels of salinity tolerance (two varieties of each level) were selected to evaluate the nucleotide sequence polymorphism in the coding region of OsHKT1;5exon 1, comparedwith that of IR28 and Pokkali checkcultivars and Nipponbare referential variety. The results of salt tolerance screening showed that the salt concentration and the rate of reduction of plant height and root length were positively correlated. Nucleotide sequence polymorphism analysis of OsHKT1;5exon 1 indicated six nucleotide substitutions (SNP) at positions 382, 418, 551, 994, 1119, and 1152. Further analysis revealed thatfive SNPs were detected withthree missense mutations (P60A, R63H, and H255D) in salt tolerant check variety (Pokkali), three to four SNPs with one to two missense mutations H255D or P60A and H255D were observed in salt moderate tolerant varieties, while salt-sensitive varieties and sensitive check variety IR28 were observed with two SNPs and one missense mutation (H255D).

Abstract. Simarmata M, Apriantonedi R, Setyowati N, Pujiwati H. 2023. Possibility of glyphosate-resistant goosegrass (Eleusine indica) in citrus fields in Rejang Lebong Districts, Bengkulu, Indonesia. Biodiversitas 24: 3633-3638.Weed abundances dominated by goosegrass (Eleusine indica L.) are a major constraint in the citrus fields of Rejang Lebong District, Province of Bengkulu, Indonesia. The objectives of this research were to investigate weed control methods applied by citrus farmers, analyze the dominant weed, and study the possibility of glyphosate resistance in goosegrass. A survey was conducted by interviewing three citrus farmers regarding weed control measures, followed by weed assessment in 10 sampling plots of each location. Then, field trials were conducted to evaluate glyphosate efficacy on weeds in the three locations of citrus fields. The survey found that glyphosate has been applied for weed control up to 4 L ha-1( 1.92 kg a.i. ha-1 of isopropyl amine salt) 2 to 3 times a year, and the farmers found that some weeds were resistant to glyphosate. Weed assessment showed that goosegrass is a dominant species with a summed dominance ratio (SDR) of 67.1, 70.8, and 79.0% at each location, respectively. The field trials observed that the levels of survival weeds in the experimental plots treated with glyphosate at 0.5, 1.0, 2.0, 4.0, and 8.0 L ha-1were 94-95%, 83-85.3%, 70-73.3%, 20-29%, and 10-12.3%, respectively. Goosegrass was identified as the survivor's weeds. The glyphosate doses (LD50) required to eradicate 50% of the weed populations ranged between 2 and 4 L ha-1 at the three sites. This study proved that goosegrass in the citrus groves of Rejang Lebong District, Bengkulu, is resistant to glyphosate.

Abstract. Samanta A, Bera B, Karmakar P. 2023. Pollination ecology of an important medicinal plant Hellenia speciosa (J.Koenig) S.R.Dutta of Asiatic tropics. Biodiversitas 24: 3152-3161. Plants often show various floral traits that help them to achieve reproductive fitness. Floral adaptive traits help to maximize the possibility of outcrossing, even for clonally propagated plants. Furthermore, seed setting through successful pollination increases genetic diversity in clonal populations. This present study aimed to describe the flowering phenology, flower biology, pollinators, and breeding system of Hellenia speciosa, a perennial herb with rhizomes from the Costaceae family. According to our study, a pollen-ovule ratio of 210:1 indicates that the plant tends to facultative autogamy; however, the plant exhibits traits such as a large landing labellum for pollinators, bilabiate floral architecture, nototribic blossoms, a prominent nectar guide, abundant floral nectar (27.64±2.661 µL/flower), and high seed set through xenogamy (68.6± 3.07 standard error) to improve reproductive success through outcrossing. Here, the plant is pollinated by two hymenopteran members, namely Xylocopa auripennis and Amegilla zonata. Despite its ample nectar production, the plant is hardly visited by any honey bee species. GCMS analysis of floral nectar found 2-hexanol and derivatives of xylose were probably responsible for pollinator specificity and honey bee exclusion events, respectively.

Abstract. Bautista JA, Manubag JJ, Sumaya NH, Martinez JG, Tabugo SR. 2023. Environmental DNA (eDNA) metabarcoding and fish visual census reveals the first record of Doboatherina magnidentatain the Philippines. Biodiversitas 24: 3063-3072. Biodiversity monitoring is the cornerstone for conserving marine fish species. However, classical methods, like the Fish Visual Census (FVC), are often limited due to sampling difficulties, the occurrence of rare and cryptic organisms, and reliance on a taxonomic expert for species identification. Recently, environmental DNA (eDNA) metabarcoding has been suggested as a non-invasive, powerful tool for biomonitoring. This study evaluates the eDNA approach as complementary tool for the FVC data in species detection and identification of important marine fishes from the marine sanctuary of Dalipuga, Iligan City, Philippines. The findings obtained through the eDNA approach provide insights into identifying significant fish species. Notably, the presence of the Hippocampus kuda Bleeker, 1852 (yellow seahorse), categorized as a vulnerable and threatened species, was detected. Additionally, the study identified Herklotsichthys quadrimaculatus Rüppell, 1837 (bluestripe herring), a native species to the Philippines that may pose potential risks to humans and the ecological balance. Furthermore, two demersal fish species, namely Large-scale whiting (Sillaginops macrolepis Bleeker, 1858) and Large-scale mullet (Planiliza macrolepis Smith, 1846), were also detected. The eDNA approach also delineated the morphologically cryptic fishes from Scaridae (parrotfishes) and Mugilidae (mullet fish) taxa to the species level. The highlight of this study was the detectionof the new Indo-pacific atherinomorine fish species Doboatherina magnidentata, which to the best of our knowledge, was the first record in the Philippine marine waters. Despite the efficiency of the eDNA metabarcoding in fish species detection and identification, the viability of eDNA in the marine environment and biases of the primer limit this method. Thus, the classical method must complement the molecular approach for better taxonomic resolution and community analysis. Future studies were also recommended to use a multigene eDNA approach to improve taxonomic sensitivity and reduce primer biases.

Abstract. Suwardi AB, Syamsuardi, Mukhtar E, Nurainas. 2023. The diversity and regional conservation status of wild edible fruit species in Sumatra, Indonesia. Biodiversitas 24: 3245-3257. Sumatra Island is recognized as the distribution center of tropical fruit species in Indonesia. However, increased human activity threatens the existence of edible wild fruit plants in nature. The study aims to assess the diversity and regional conservation status of wild edible fruit plant species in Sumatra, Indonesia. The study was conducted in four provinces: West Sumatra, Riau, Jambi, and Bengkulu. For the sampling, a modified line transect method was used. A total of 331 wild edible fruit plant species at four studied sites in Sumatra consisted of 73 families. The highest number of fruit plant species was recorded in West Sumatra Province, i.e., 176 species, followed by Jambi (172 species), Riau (121 species), and Bengkulu (76 species). The diversity of wild edible fruit plant species was higher in West Sumatra Province (3.85) but lower in Riau Province (3.25). Artocarpus integer (Thunb.) Merr., Baccaurea lanceolata (Miq.) Müll.Arg., Baccaurea macrocarpa (Miq.) Müll.Arg., Baccaurea polyneura Hook.f., Garcinia atroviridis Griff. ex T.Anderson, Garcinia xanthochymus Hook.fil. ex J.Anderson, Mangifera foetida Lour., Mangifera laurina Blume, Mangifera odorata Griff., and Pometia pinnata J.R.Forst. & G.Forst. were the most frequently recorded wild fruit plant species in all of the study area. However, 74 wild edible fruit plant species were recorded only in West Sumatra, 45 in Riau, 79 in Jambi, and 9 in Bengkulu. Among the 331 wild edible fruit species in the present study, 1 taxon was classified as endangered (0.30%), 9 taxa (2.72%) as vulnerable, 11 taxa (3.32%) as near threatened, and 139 taxa (41.99%) as least concern, and 171 taxa (51.67%) as Data Deficient.

Abstract. Sulton MN, Putri NRA, Nugraheni RS, Afifah RN, Fadilah RN, Indrawan M, Kusumaningrum L, Sutarno, Sunarto, Sugiyarto, Pradhan P, Setyawan AD. 2023. Estimating carbon storage using remote sensing in the Selo Resort forest area of Mount Merbabu National Park, Central Java, Indonesia. Biodiversitas 24: 6264-6270. This study is of paramount importance for long-term climate change mitigation efforts, as it aims to estimate carbon storage and assess land cover density in Selo Resort forest area of Mount Merbabu National Park (MMbNP), Central Java, Indonesia, utilizing remote sensing techniques. Sentinel 2A satellite imagery, acquired on May 28, 2023, serves as the foundational dataset for this research. Employing ArcGIS 10.5, the satellite imagery was processed to derive the Normalized Difference Vegetation Index (NDVI), a critical parameter in this analysis. The NDVI values were subsequently employed to categorize land cover density, leading to the classification of land into five distinct classes: non-vegetation, shrubs, low density, medium density, and high density. This classification process enabled the determination of land cover density. The calculated values for each density class, namely low, medium, and high-density land cover, revealed substantial carbon storage potentials: 12,357.99 tons C, 92,871.04 tons C, and 73,542.06 tons C, respectively. Moreover, the computed areas for low, medium, and high-density cover were 202.59 ha, 364.93 ha, and 348.26 ha, respectively. This study underscores the need for ongoing monitoring to detect changes in land cover and to implement afforestation initiatives in areas with low-density vegetation. Such efforts are crucial for the preservation of land cover and the associated carbon storage benefits, thereby contributing to broader climate change mitigation strategies.

Abstract. Aulia R, Kaswanto, Arifin HS, Mosyaftiani A, Syasita N, Wahyu A, Wiyoga H. 2023. Assessing the benefits and management of urban forest in supporting low carbon city in Jakarta, Indonesia. Biodiversitas 24: 6151-6159. Climate change is a phenomenon that has become a global concern including in urban areas. Jakarta is one of the most populated cities in Indonesia, reaching 10.56 million people in 2020 with high emissions levels due to high human activities. Thus, efforts to reduce carbon emissions to mitigate climate change are necessary in Jakarta one of which is through the concept of low carbon city and manifested in the establishment of Green Open Space (GOS), including urban forests. Urban forests aim to sequester and store carbon, and improve the urban microclimate. This research aimed to assess the benefits of urban forests in Jakarta in term of their capacity in carbon sequestration using i-Tree Eco tool, and analyse the management of urban forests related to the applicable regulations. To collect data on trees, this study created 49 plots scattered across Srengseng Urban Forest, Cipayung Urban Forest, Munjul Urban Forest, Rawa Malang Urban Forest, and Pondok Labu Urban Forest. Tree species, Diameter at Breast Height (DBH), total tree height, live tree height, crown base height, crown width, percent crown loss, and crown light exposure were all gathered. Furthermore, in-depth interviews with urban forest managers were performed to gather additional information on present management, including questions derived from Jakarta's green open space legislation to assess management efficacy. The results of the analysis of urban forest quality show that the health status of trees is one of the factors that indicate the quality of urban forests at the five study sites, with more than 50% of the total trees in fair condition (75- 90% health). The gross carbon sequestration of trees in five urban forests Jakarta is about 184.8 metric tons of carbon per year. Additionally, the in-depth interviews also test the mortality of the urban forest, a decent indicator of current management with estimates over the next 10 years, showing a slight increase in carbon sequestration and storage capacity. However, the mortality scenario leads to a trend toward a decrease in leaf area and the number of tree categories, especially in the Srengseng Urban Forest.
