Abstract. Solfiyeni, Syamsuardi, Chairul, Mukhtar E. 2022. Impacts of invasive tree species Bellucia pentamera on plant diversity, microclimate and soil of secondary tropical forest in West Sumatra, Indonesia. Biodiversitas 23: 3135-3146. The invasion of alien species in a region can alter species diversity. Bellucia pentamera Naudin is considered an alien invasive plant that has spread from Mexico to tropical America, and it is now invading some areas in Indonesia, including the tropical forest of Sumatra. Yet, the effects of its invasion on vegetation and the abiotic environment are not yet well understood. The objective of this study was to investigate the impacts of B. pentamera on species diversity and structure of vegetation, and microclimate and soil conditions of secondary tropical forests in West Sumatra. Vegetation analysis was conducted in secondary forest Bukit Tengah Pulau, South Solok, with three levels of dominance of B. pentamera namely: site 1 and 2 (60% and 16% dominance of B. pentamera respectively) and site 3 (no individual of B. pentamera). Sampling was conducted using a nested plot to collect data for tree, sapling and understorey vegetation for each site. The results showed the total number of tree species at sites 1, 2, and 3 were 23 species, 46 species, and 74 species respectively. For sapling, 20 species were found at site 1, 31 species at site 2, and 58 species at site 3. For understorey plants, 13, 16 and 36 species were detected at site 1, 2 and 3 respectively. The number of species at tree and sapling levels differed significantly among sites. The basal area also differed significantly among sites but not for sapling level. Site 1 was dominated by B. pentamera with Important Value Index (IVI) 130.8%), followed by Croton argyratus (27.63%), and Ficus variegata (26.47%). At site 2, B. pentamera dominated with IVI of 33.68%, followed by Lepisanthes sp. (20.01%) and Sizygium sp. (14.44%). Site 3 was dominated by Palaquium warsurifolium with IVI of 21.15% followed by Croton argyratus (20.02%) and Macaranga hypoleuca (13.21%). Diversity index (H') for tree-level was moderate at site 1 (H' = 1.78) and high at sites 2 and 3 (H' = 3.48 and 4.05). Similarly, the index for sapling was moderate at site 1 (H'= 2.12) and high at sites 2 and 3 (H'= 3.22 and 3.84). For understorey, the diversity index was low at site 1 (H'= 0.82) and moderate at sites 2 and 3 (H'= 1.8 and 2.86). Sites invaded by B. pentamera had a lower soil water content and higher temperature and light intensity, although they had higher nitrogen and phosphorus contents. Our findings suggest that the invasion of B. pentamera had negative impacts on plant biodiversity and microclimate, yet the impact was not clear cut on the soil.

Abstract. Tapilatu RF, Wona H, Mofu B, Kolibingso D, Alzair N, Erdmann M, Marunaya B. 2022. Foraging habitat characterization of green sea turtles, Chelonia mydas, in the Cenderawasih Bay, Papua, Indonesia: Insights from satellite tag tracking and seagrass survey. Biodiversitas 23: 2783-2789. The distribution area of green turtles is not yet known in Cenderawasih Bay. On 20 November 2020, two satellite transmitters were attached to two female green turtles (Chelonia mydas Linnaeus, 1758) on Kalilemon, Southwest Cenderawasih Bay, Papua Province, Indonesia. Kalilemon area and Mangga Island as part of Kwatisore waters are the major foraging areas for this species and are under threat of turtle opportunistic poachers. The results show that the two turtles (Mary and Nona) dispersed and used limited but consistent and different foraging grounds during the tracking period through the satellite tags between November 2020-April 2021 at Mangga Island and Kalilemon. The composition of seagrass at both stations consisted of the same five species belonging to the families Cymodoceae and Hydrocharitaceae, with relatively different qualitative abundances. Overall, the mean chlorophyll-a content during the study period from November 2020-April 2021 ranged from 0.25-0.55mg/m3 at both foraging grounds (Mangga Island and Kalilemon). The mean SST during the study period ranged from 30.61-31.77oC in both locations. Before the next tracking attempt, more data on seasonal foraging and nesting activities are required. The result of this research is vital to determine the foraging grounds for green turtles related to the seagrass species with its abundance and key environmental factors in the management and conservation of sea turtles in the Cenderawasih Bay area.

Abstract. Novriyanti N, Takandjandji M. 2022. Application of sexual dimorphism-derived variation in morphometrics and intraspecific interaction likelihood in Sunda pangolin (Manis javanica) to increase species encounter rates. Biodiversitas 23: 2753-2759. Effectively encounters opportunities of Sunda pangolin (Manis javanica) in natural habitats is still necessary to have more research. A diversity of pangolins' physical and biological characteristics has been disclosed to facilitate the identification process in natural habitats. However, pangolins are animals that tend to be solitary; they have fast movement, so the area coverage is extensive; this condition complicates the data collection process. It is unknown yet, whether pangolins of different sexes usually exist in the same space and time, either in terms of foraging or other interactions, known as intra-specific interactions. Thus, this study aimed to predict intraspecific interactions of M. javanica to increase the encountering of pangolins chance in natural habitats. As many as 29 individual pangolins (14 males and 15 females) be measured its morphometric data. To convincingly justify that morphometric variation can be used as encounter rate opportunities in natural habitats, a series of analyses, i.e., univariate test, correlation analysis, and multiple regression, were applied to this research. Other estimations from feeding activity data were also carried out to detect pangolins' niche width and its overlap according to sexual dimorphism. Univariate analysis shows that overall, the total body length (head to tail) of both males and females does not differ significantly. But, the correlation coefficient indicates the physical character of female and male body length is related to each other (value 0.769**). The resulting regression model indicates that the presence of pangolins in their sex similarity in a particular place tends to be avoided, while there is a 1:1 probability of sexual dimorphism. This also means that males and females can be used as the same individual in ecological observations.

Abstract. Ruzmetrov R, Abdullaev I, Gandjaeva L, Matyakubov Z, Iskandarov A, Otaev O, Ibragimov S. 2022. Fundamentals of using Geographical Information Systems in predicting the distribution of Helicoverpa armigera (Lepidoptera: Noctuidae). Biodiversitas 23: 3251-3256. This study aims to explore new ways to identify agroecological conditions that help in the occurrence of Helicoverpa armigera in cotton fields. Geographical data on soil salinity, mechanical composition, groundwater level, salinity, density of canals and drains, field Normalized Difference Vegetation Index (NDVI) coefficient of the field Helicoverpa armigera with the number of eggs regression was analyzed. The data were collected from the database of the GIS laboratory of the KRASS (Khorezm Rural Advisory Support Service) agro-consulting center, which was established with support from ZEF (The Center for Development Research) University of Bonn, Germany, and lancet satellite data in the calculation of NDVI. Data were analyzed with ArcGIS and R program. Occurrence of Helicoverpa armigera in cotton fields was found to be associated with high relative humidity and high stem length. Using the relative humidity of the air in the field and other agroecological factors, it was found that the probability of remote distribution of cotton bollworm is more than 50%.

Abstract. Das B, Roy S, Kalita S, Boro KK, Nath M, Nath N. 2022. Comparative foliar morphological and palynological studies of Cleomaceae of Assam, India. Biodiversitas 23: 2920-2934. The Cleomaceae is a well-known angiospermic family. There is no record of extensive study on the members of the family Cleomaceae in the state of Assam. Though the species Cleome houtteana is found abundantly in the studied area, it was not reported in any of the major floristic works of the region and it was misidentified as Gynandropsis gynandra by many of the earlier workers. So, the present work was carried out to do a detailed comprehensive study on the morphology, foliar macro and micro-morphology (epidermis, stomata, and trichome), leaf venation pattern, along with palynological characters of the four species of Cleomaceae viz. Gynandropsis gynandra, Cleome houtteana, Sieruela rutidosperma, and Arivela viscosa of Assam, India. These species show similarities with each other, but can be well differentiated using the studied characters here. Detailed taxonomic descriptions have been given along with relevant information and color photographs for the correct identification of all four different species.

Abstract. Benmakhlouf Z, Benserradj O, Kellab R. 2022. Short Communication: Identification of phytochemical constituents of Syzygium aromaticum L. using gas chromatography coupled with mass spectrometry and evaluation of antimicrobial activity. Biodiversitas 23: 2586-2593. Syzygium aromaticum L. is a traditional spice that has various pharmacological activities attributed to its content of bioactive molecules. The purpose of this work is to evaluate phytochemical constituents of S. aromaticum L. extract using gas chromatography coupled spectrometry mass (CG/MS). The number detected of phenolic compounds was 45, which the most abundant being eugenol (54.63%), followed by Phenol,2-metoxy-4-(2-propenyl)-, acetate (eugenol acetate) (21.57%) and caryophyllene (16.71%). In addition, the antimicrobial activity was screened by the paper disc diffusion method for three bacterial strains, (Pseudomonas aeruginosa ATCC 27853, Salmonella sp. and Staphylococcus aureus 6538) and by the direct contact method on three fungal strains (Aspergillus niger, Aspergillus flavus and Candida albicans). The results showed that extract presents an inhibitory activity with all the strains tested. Salmonella sp. is very sensitive (++) to the stock solution (100mg/ml), sensitive (+) to dilutions (50 and 25) mg/ml with inhibition diameters of (16, 12, 10) mm respectively. The other bacterial strains are sensitive (+) only to the stock solution. The results of our experiment confirm that fungi strains: A. niger, A. flavus and C. albicans show a remarkable antifungal activity at 100mg/ml. The result indicated that the extract obtained from dried buds of S. aromaticum could be considered an agent for antibacterial and antifungal in the pharmaceutical field.

Abstract. Widiarti R, Zamani NP, Bengen DG, Madduppa H. 2022. Molecular characterization of toxic benthic dinoflagellate, Prorocentrum lima in west Indonesian waters using LSU 28S rDNA gene. Biodiversitas 23: 3257-3263. Prorocentrum lima is one of the toxic benthic dinoflagellates known to cause Diarrhetic Shellfish Poisoning (DSP), which is also associated with ciguatoxin-producing species, Gambierdiscus toxicus that causes Ciguatera Fish Poisoning (CFP). P. lima has a wide range of morphological variability and genetic diversity, but such research has never been reported from Indonesian waters yet. This study aimed to determine the molecular characteristics of P. limain west Indonesian waters, namely Bintan Island, Belitung Island, Seribu Islands, and Karimunjawa Islands. Molecular characterization was conducted by amplification on large subunit (LSU)28S rDNA gene. Extraction was conducted using freeze-thaw which was continued with single cell PCR method. Genetic distance values and phylogenetic analysis were analyzed using MEGA software. Based on molecular analysis, P. lima from this research was divided into two subclades, namely subclade A from Seribu Islands and Belitung Island, and subclade B from Karimunjawa Islands and Bintan Island. P. lima from Bintan Island showed a closer relationship with the reference sequence from the Genbank. Observation of molecular characters of P. lima showed that the genetic diversity of P. lima depended on the variation of the island’s morphogenesis type.These findings could support a further study on the distribution of P. lima in Indonesian waters, related to the genetic variation and toxin production, since Indonesia consists of many small islands.

Abstract. Effendy J. 2022. Isolation and characterization of IbAE7-like 1 gene encoding the cytosolic iron-sulfur cluster assembly pathway in response to skinning injury in sweetpotato. Biodiversitas 23: 4223-4233. Skinning injury is a major constrain in postharvest loss in sweetpotato due to the loss of skin from the surface of the roots. ASYMMETRIC LEAVES1/2 ENHANCER7(AE7) is an important cytosolic iron-sulfur (Fe-S) protein assembly (CIA) pathway. A partial cDNAIbI51 encoding AE7-like 1 was isolated from a skinning injury cDNA library to evaluate its potential role in response to skinning injury. The open reading frameof IbAE7-like 1 consisted of 324 nucleotides and the deduced polypeptide sequences consistedof 108 amino acids with missing 46 amino acid residues at 5? end. The amino acid sequence ofIbAE7-like 1 shared 100% identity toAE7-like 1 previously identified in Ipomoea triloba and Ipomoea nil and 89.91-100% identity from other plants species. The findings indicated that AE7-like 1 was highly conserved in Ipomoea sp. In addition to similarity to AE7-like 1, IbAE7-like 1 also showed similarities to MIP18 (89.91-93.52%); DUF59 (91.67%); FAM96B (90.74%); and proteins with unknown function (90.74-91.67%). IbAE7-like 1 mRNA transcripts showed transient expression in response to skinning injury. The phylogenetic analysis classified IbAE7-like 1 into three main classes. This study revealed IbAE7-like 1 may play a key role in plant defense and wound repair to prevent DNA damage due to skinning injuryin storage roots of sweetpotato.

Abstract. ‘Aini K, Elfita, Widjajanti H, Setiawan A. 2022. Diversity and antibacterial activity of endophytic fungi isolated from the medicinal plant of Syzygium jambos. Biodiversitas 23: 2981-2989. Currently, antimicrobial resistance is one of the most important threats to global public health. This is due to the various mechanisms of antimicrobial resistance. Thus, the need for new sources of bioactive compounds outside conventional antibiotics is a top priority. This investigation evaluated the diversity and antibacterial activities of endophytic fungi isolated from the leaves and root bark of jambu mawar (Syzygium jambos (L.) Alston). The endophytic fungi were grown on PDA media, and their antibacterial activities were tested using the Kirby-Bauer method on two Gram-positive and two Gram-negative bacteria. A total of 10 (SJD1-SJD10) and 11 isolates (SJA1-SJA11) of endophytic fungi were identified from the leaves and root bark of S. jambos, respectively. Among them, SJA8 isolate exhibited strong antibacterial activity. Based on morphological characterization and phylogenetic tree analysis, SJA8 was identified as Pleiocarpon livistonae. Isolation and identification of pure compounds from the fungi may reveal potential candidates for new antibiotic substances.

Abstract. Purba RTT, Dauzi F, Sari RW, Naibaho DC, Putri QA, Maulana A, Hastutui LDS, Punnapayak H. 2022. Arthrobotrys thaumasia and Arthrobotrys musiformis as biocontrol agents against Meloidogyne hapla on tomato plant. Biodiversitas 23: 3659-3666. The use of nematode-trapping fungi as a biocontrol agent is an environmental-friendly step in controlling Meloidogyne hapla on plants. The aim of this study was to determine the potential of A. thaumasia and A. musiformis as biocontrol agents in reducing the attack of M. hapla on tomatoes (Solanum lycopersicum). The isolates were tested for their biocontrol ability against M. hapla using a completely randomized design (CRD) with five treatments: K+ (positive control), K- (negative control), KBF (Carbofuran), and two treatments of nematode-trapping fungi (A. thaumasia and A. musiformis). Root length, root weight, stem length, and stem weight of tomato plants were observed. The results showed that A. thaumasia and A. musiformis could reduce M. hapla in tomato plants up to 93% and 97%, respectively. Number of root-knot infections caused by M. hapla in tomato was found lower in JPN2 treatment, followed by JPN1 treatment. It was also recorded that JPN2 isolate treatment was able to produce the highest values of root length, root wet and dry weight, stem length, and stem wet and dry weight as compared to JPN1 isolate treatment.
