Abstract. Ilhamdi ML, Idrus AA, Santoso D, Hadiprayitno G, Syazali M. 2021. The species richness and conservation priority of dragonflies in the Suranadi Ecotourism Area, Lombok, Indonesia. Biodiversitas 22: 1846-1852. Dragonflies are insects that have attractive colors and play an important role to balance ecosystems. They also act as bioindicators of the aquatic environment. The purpose of this study was to investigate the species richness and conservation priorities of dragonflies in the Suranadi Ecotourism Area, Lombok, Indonesia, expecting that the dragonflies will be used as charismatic species to support ecotourism. The research was conducted in August-December 2020 by surveying transect lines across 9 types of habitat. We then determined the conservation priority for each species found by referring to the Government Regulation using scoring method through a Focus Group Discussion (FGD) involving five experts. The score for each species was determined based on the percentage of the opinion from the experts. We found 18 dragonfly species from 2 suborders (Zygoptera and Anisoptera) and 5 families (Chlorocyphidae, Coenagrionidae, Platycnemididae, Aeshnidae and Libellulidae). The habitat type that supports the highest species richness was the waterway and irrigation (16 species), while the lowest species richness was found in the areas inside the forest habitat (2 species). The species that had the highest conservation priority scores were Pseudagrion pilidorsum declaratum, Libellago lineata, and Gynacantha subinterrupta. These three species can be used as conservation priority species in the ecotourism area of Suranadi, Lombok, Indonesia.

Abstract. Nelly N, Hamid H, Lina EC, Yunisman. 2021. Distribution and genetic diversity of Spodoptera frugiperda J. E. Smith (Noctuidae: Lepidoptera) on maize in West Sumatra, Indonesia. Biodiversitas 22: 2504-2511. Fall Armyworm (FAW), Spodoptera frugiperda is a major maize pest, reportedly entering West Sumatra, Indonesia in early 2019. After a year of its discovery, there has been no information on the distribution and genetic diversity of this pest. In the present study, research has been carried out to obtain reliable information on the spread, incidence, and genetic diversity of this pest during July-October 2020 at the maize production center of West Sumatra, Indonesia. Sampling was then carried out using the purposive random sampling method, on maize fields in 5 districts (West Pasaman, Padang Pariaman, Solok, Limapuluh Kota and, Tanah Datar). The sample plots were determined with a size of 1x1m2 to observe the population and incidence, meanwhile, the observations were recorded on the larvae number and the percentage damage. Each district location's genetic diversity was analyzed based on the mitochondrial cytochrome c oxidase subunit I (COI) gene nucleotide variations amplified with specific primers. The observations show that S. frugiperda had attacked all maize planting sites in West Sumatra with the attacks ranging percentage from 12.78 to 41.25% and an average larval population of 0.26-1.05 larvae / 2 plants. The genetic diversity analysis results of the S. frugiperda West Sumatra population, on the phylogenetic tree, were divided into two groups, the first is group A which consisted of West Pasaman isolates, and Solok isolates. The second, Group B consisted of Padang Pariaman, Limapuluh Kota, and Tanah Datar isolates (The percentage genetic similirity 99.86-100%). The S. frugiperda population genetics in West Sumatra are similar to those isolates from several other countries in the world.

Abstract. Markus JER, Ndiwa ASS, Oematan SS, Mau YS. 2021. Variations of grain physical properties, amylose and anthocyanin of upland red rice cultivars from East Nusa Tenggara, Indonesia. Biodiversitas 22: 1345-1354.  Red rice is becoming more popular nowadays due to the increasing awareness of rice consumers on its health benefits. The demands for red rice are increasing but the supply is limited, thus, local red rice cultivars can be used to fill this gap. Optimal use of local rice germplasm requires a comprehensive evaluation of their traits, and the genotypes having the most desirable traits can be selected for direct use. Several upland red rice cultivars from East Nusa Tenggara Province have been evaluated for various traits while their grain properties are still unrevealed. Information on grain properties is important, both for consumer preference and rice breeders. This study aimed to elucidate the grain physical properties, amylose, and anthocyanin of upland red rice germplasm from ENT Province, and to identify genotypes with the most desirable characters for further employment. Eighteen rice genotypes were used in this study. They were cultivated in the field, and the harvested grains were analyzed in the laboratory. Both ANOVA and descriptive statistics were used for data analysis. Substantial variations were observed on all variables, except the chalky grain percentage. The kernel length of tested genotypes was classified as long, medium, and short while the kernel shapes were slender, medium, and bold. Most tested genotypes had high head rice percentage and low to medium percentages of large and small broken kernels. Chalky grain was almost absent. Amylose content ranged from 1.0% to 28% while anthocyanin was about 1.0 - 20 mg/100 g. The evaluated genotypes were clustered into three main groups. Percentages of large and small broken kernels, and amylose content were mostly responsible for the observed variations among the rice genotypes. The red rice genotypes were diverse in the studied characters, thus, those with desirable grain characters are useful for further development and utilization.

Abstract. Mohd-Asri NF, Kamaluddin SN, Dharmalingam S, Idris WMR, Md-Zain BM. 2021. Valuing ecotourism in Bukit Merah Orang Utan Island, Malaysia based on visitors’ experience. Biodiversitas 22: 1543-1549. Ecotourism has been identified as one of the alternative ways of boosting a region's economic status and highlighting the necessity of a healthier tourism sector. Bukit Merah Orang Utan Island (BMOUI) is the only ex-situ conservation center promoting primate ecotourism on the Malay Peninsula. We conducted a primate ecotourism survey at BMOUI to determine six ecotourism expressive valuations for describing the quality of tourists’ visits to BMOUI and estimating tourist’s willingness to pay (WTP) in relation to the entrance fee. Surveys were completed by 100 randomly selected respondents aged at least 18 years. Likert scale items and Cronbach’s alpha were used in the data analyses. Six ecotourism experiences (hedonic, interaction, novelty, comfort, stimulation, and safety values) were further analyzed using statistical software. The results showed that visitors experienced moderate hedonic experience (44.8%), moderate interactive value (42.35%), moderate novelty value (42.5%), medium comfort value (42.5%), medium stimulation value (42.7%), and low security value (37.15%). In addition, the mean WTP, determined by the bidding process, was about RM54.90 per visitor for each visit. The findings of ecotourism experiences and the estimated price can provide important information to BMOUI administrators. This study will contribute indirectly to upgrading the level of awareness of primate conservation aspects among tourists, entrepreneurs, and locals.

Abstract. Prasetyo J, Ginting C, Akin HM, Suharjo R, Niswati A, Afandi A, Adiwijaya R, Sudiono, Nurdin M. 2021. The effect of biological agent and botanical fungicides on maize downy mildew. Biodiversitas 22: 1652-1657. This study was conducted to evaluate the effect of the combination of Trichoderma asperellum and mycorrhizae with botanical fungicides made from betel leaf extract or turmeric extract against maize downy mildew. The study used a randomized complete block (RCB) design with three replications. The treatments applied were: single applications of T. asperellum (Ta); arbuscular mycorrhizal fungi (AMF); turmeric extract (T); betel extract (B); the combination of T. asperellum and AMF (TaM); turmeric extract and T. asperellum (TTa); turmeric extract and AMF (TM); turmeric extract + T. asperellum + AMF (TTaM); betel extract + T. asperellum (BTa); betel extract + AMF (BM); betel + T. asperellum + AMF (BTaM); and Control (C). The observed variables were disease incidence, incubation period, and shoot dry weight. The data were analyzed using ANOVA. Differences between treatments were tested by the LSD test at 5% significance level. The results showed that the combination of botanical fungicides with biological agents could reduce the incidence of downy mildew, extend the incubation period, and increase the dry weight of corn shoots. The best combination treatment was achieved from the combination of T. asperellum with betel extract. There was a synergistic effect between botanical fungicides and biological agents in reducing the disease incidence.

Abstract. Setyadi G, Pribadi R, Wijayanti DP, Sugianto DN. 2021. Mangrove diversity and community structure of Mimika District, Papua, Indonesia. Biodiversitas 22: 3562-3571. Despite being one the largest mangrove forest in the world, there are few studies on mangrove diversity and community structure in Mimika, Papua Province. The study collected data from 4 estuaries of Mimika Region, i.e. Kamora, Tipuka, Ajkwa and Minajerwi. Mangrove species, tree diameter at breast height and canopy height data were collected in 10 m x 10 m plot with three replicates for distance, specifically 0, 250, and 500m perpendicular to the riverbank. This study found 66 mangroves species consisting of 20 major, 10 minor, and 36 associate mangrove species. Their density ranged from 577-1,345 trees ha-1 with diversity Shannon-Weiner diversity indices (H’) ranging from 0.62-1.19 and Evenness Index (J’) ranging from 0.09-0.18. The canopy height of the mangrove trees was ranged from 9-42.5 m. The highest density species was Rhizophora apiculata (333 ha-1) followed by Avicennia marina, Bruguiera gymnorrhiza, and Camptostemon schultzii, while B. parviflora, S. alba, and X. granatum were the least dominant. Regarding basal area, R. apiculata and B. gymnorrhiza were the highest with medians of 7,853 cm2 ha-1 and 5,201 cm2 ha-1 respectively. In the low tidal zone area, mangrove was dominated by A. marina, Sonneratia alba and R. mucronata. Medium low to medium high tidal zones were dominated by B. gymnorrhiza, R. apiculata, and B. parviflora. The high tidal zone was more dominated by Nypa fruticans.

Abstract. Desrita, Hasugian FK, Yusni E, Manurung VR, Rambey R. 2021. Feeding habits of Tinfoil barb Barbonymus schwenenfeldii in the Tasik River, South Labuhanbatu, North Sumatra, Indonesia. Biodiversitas 22: 2131-2135. Research on feeding habits of Tinfoil barb, Barbonymus schwanenfeldii was carried out in the Tasik River from July to August 2020. This study aims to determine the composition of foods consumed by Tinfoil barb fish, and the availability of natural food in the Tasik River from 3 sampling stations. Fishes were caught using a gillnet with a mesh size of 3.18 cm, then the fish samples were dissected, and the digestive tract was taken and preserved with 10% formalin. A total of 138 Tinfoil bars were caught for this study. Analysis of stomach contents found that Tinfoil barb ate phytoplankton (41-48%) as the primary food, moss (25-38%), plant pieces (13-17%), worms (2-11%) as a complementary food and few of insects (0-4%), zooplankton (0-1%) as other foods. Based on analysis of food item values, all types of food and ratio within the intestine length and the total length showed that Tinfoil Barb was classified as omnivorous. The availability of natural foods for Tinfoil Barb in the Tasik River consists of the genera Asteroinella, Bacillaria, Bidulphia, Cestom, Gyrosigma, Gonatozygon, Oscillatoria, and  Thalassiora.

Abstract. Majeed W, Khawaja M, Rana N. 2021. Assessing fluctuation of ant populations in a distinct ecological habitat to track climate change effects. Biodiversitas 22: 2722-2727. Ants are an indicative group of terrestrial invertebrates that play an important role in soil fertility by clearing the soil surface of vegetation. This study focuses on the composition and structure of ant communities in two sampling stations: Domestic and Wild areas. Ant fauna was collected over a period of six months using an inline-fixing technique combined with pitfall traps and hand sampling. A total of 30 ant species were collected, belonging to 15 genera in four subfamilies: Formicinae, Myrmicinae, Dolichoderinae, and Dorylinae. The maximum population was recorded in the Wild area due to dense forest vegetation present at this station. The most abundantly found species in the Domestic area was Lasius niger, while Formica spp. was most common in the Wild area. Diversity (H) and Margalef Richness indices were recorded higher for the Wild habitat, while Evenness was found higher in the Domestic habitat. Statistical analysis showed that the abundance and species richness were highly significant for both habitats (p < 0.001). Ant populations showed significant variation with temperature and humidity; for example, an increase in temperature and low humidity favored the abundance of ants. Being the first such study in the region, the results add significantly to the understanding of this terrain’s ecology.

Abstract. Fellahi A, Djirar N, Cherief A, Boudrissa A, Eddaikra N. 2021. Zoonotic cutaneous leishmaniasis and Leishmania infection among Meriones shawi population in Setif Province, Algeria. Biodiversitas 22: 2547-2554. Zoonotic cutaneous leishmaniasis (ZCL) is the most endemic disease in Algeria. Leishmania major is the causative agent, and Gerbils Meriones shawi and Psammomys obesus are the main reservoir hosts. The Province of Setif in Algeria has become a very active focus for this zoonosis. Our study was carried out from January 2017 until January 2019 in ten representative stations of the study area, with an aim to identify the association between zoonosis and reservoir host species. Eighty-six (86) specimens of M. shawi and three (3) specimens of P. obesus were captured and determined. Superficial lesions were subjected to Giemsa stained smears. In addition, Livers and spleens were tested for Leishmania DNA using ITS1 PCR. The results showed the presence of M. shawi in almost all communities of Setif Province and the highest population with 50 specimens (58.13%) was in the center and south. The microscopic and molecular detection of Leishmania showed high infestation in most specimens of Meriones (32/86) with a rate of 37.20 %, however, no infestation in Psammomys has been detected. The PCA results showed a negative association between rainfall and ZCL cases; however, positive association was found between temperature and the human CL cases. Also, positive association was demonstrated between ZCL in south and center of Setif Province and Meriones captured. Our finding, confirm that M. shawi is the principal reservoir host (76.78%) of the ZCL in Setif Province, since P. obesus was nearly absent (2.67%).

Abstract. Mutaqin AZ, Kurniadie D, Iskandar J, Nurzaman M, Husodo T. 2021. Morphological characteristics and habitat conditions of suweg (Amorphophallus paeoniifolius) around Mount Ciremai National Park, West Java, Indonesia. Biodiversitas 22: 2591-2600. Indonesia is a country that has abundant biodiversity, especially the diversity of plant species. One of the plant species that widely distributed across Indonesia is Amorphophallus paeoniifolius (Dennst.) Nicolson, or locally known as suweg. This study aims to identify morphological characteristics of A. paeoniifolius and its habitat conditions around Mount Ciremai National Park, West Java Province, Indonesia. Several stages of the exploratory survey were randomly carried out followed by purposive intensive observations. The method used to collect and analyze data is qualitative methods combined with simple measurements of quantitative technique. The results showed that suweg in the studied areas had distinctive morphological characteristics, which are different from the rest of the species from Amorphophallus genus. The plant is found in 4 types of land, namely home gardens, gardens, rice fields, and pond edges, whether with open or closed canopy conditions. The density of suweg in the study area is generally low. The climatic and edaphic conditions of suweg habitat in several study areas showed that there are a lot of similarities of conditions with other references. There are also 156 species of plants found that grow around suweg, both in the category of cultivated and wild plants. This- study enriches the existing knowledge on the botanical and ecological information of A. paeoniifolius in the context of geographical area (i.e., Ciremai National Park, West Java, Indonesia).
