Abstract. Dosan R, Mudana SO, Julyanto CMP, Purnama ET, Sugata M, Jo J, Tan TJ. 2024. Isolation and identification of Bifidobacterium species from human breast milk and infant feces in Indonesia. Biodiversitas 25: 337-343. There has been a growing interest in identifying emerging probiotic strains because of their benefits for human health. Many bifidobacteria originated from humans have been reported to possess probiotics properties. They are commonly found in the intestine of breast-fed infants. Hence, this study aimed to isolate and identify bifidobacteria from human breast milk and infant fecal samples in Indonesia and evaluate their probiotic properties. Twenty colonies were isolated from two independent fecal samples and two independent breast milk samples. Ten isolates (BR1-M1, BR1-B1, BR2-5, BR2-6, BR2-12, BS2-PB3, BS2-PB5, BS2-PS1, BS2-PS2, BS2-MB1) showed a compatible phenotypic character with Bifidobacteria based on the Bergey’s Manual, including Gram-positive, irregular rods, no catalase activity, non-spore-forming, and non-motile. Subsequently, four isolates with similar carbohydrate fermentation patterns as Bifidobacterium spp. were selected for further molecular identification based on 16S rRNA gene sequencing analysis. The results showed that BR2-5 and BR2-6 were found to be closely related to Bifidobacterium animalis subspecies lactis with 100 and 98.39% similarity, respectively. Meanwhile, BS2-PS1 and BS2-PB3 were found to be closely related to Bifidobacterium breve with 100 and 98.26% similarity, respectively. Further investigation revealed that BR2-5 and BS2-PB3 were resistant to low pH (?4) and could tolerate the exposure of bile salts (1%). Both isolates survived under different oxidative stress conditions (aerobic and microaerophilic). In conclusion, BR2-5 and BS2-PB3 exhibited promising characteristics as probiotic candidates, though further investigations are required to substantiate these current findings.
摘要Dosan R, Mudana SO, Julyanto CMP, Purnama ET, Sugata M, Jo J, Tan TJ. 2024.印度尼西亚母乳和婴儿粪便中双歧杆菌的分离和鉴定。生物多样性》25：337-343。由于益生菌对人类健康有益，人们对鉴定新兴益生菌菌株的兴趣与日俱增。据报道，许多源自人类的双歧杆菌具有益生菌特性。它们通常存在于母乳喂养婴儿的肠道中。因此，本研究旨在从印度尼西亚的母乳和婴儿粪便样本中分离和鉴定双歧杆菌，并评估其益生菌特性。研究人员从两个独立的粪便样本和两个独立的母乳样本中分离出 20 个菌落。10 个分离菌株（BR1-M1、BR1-B1、BR2-5、BR2-6、BR2-12、BS2-PB3、BS2-PB5、BS2-PS1、BS2-PS2、BS2-MB1）根据《Bergey's Manual》显示出与双歧杆菌兼容的表型特征，包括革兰氏阳性、不规则棒状、无过氧化氢酶活性、不形成孢子和无运动性。随后，根据 16S rRNA 基因测序分析，选择了四种碳水化合物发酵模式与双歧杆菌相似的分离物进行进一步的分子鉴定。结果表明，BR2-5 和 BR2-6 与动物乳双歧杆菌亚种关系密切，相似度分别为 100%和 98.39%。同时发现，BS2-PS1 和 BS2-PB3 与乳酸双歧杆菌密切相关，相似度分别为 100% 和 98.26%。进一步研究发现，BR2-5 和 BS2-PB3 对低 pH 值（？这两种分离物在不同的氧化压力条件下（需氧和微嗜气）都能存活。总之，BR2-5 和 BS2-PB3 作为候选益生菌表现出了良好的特性，但还需要进一步的研究来证实目前的这些发现。

Abstract. Agoto Jr. RNA, Hernandez JO, Park BB. 2024. Morphoanatomy and physiology of Swietenia macrophylla in different light environments: Insights into its invasive ability in the Philippines. Biodiversitas 25: 257-263. Evidence supporting Swietenia macrophylla G.King's invasive ability is primarily inferential to date. The present study analyzed the variation in morphoanatomical and physiological traits of the species between shaded and sun-exposed environments to provide insights into its invasive ability in the Philippines. The variations in leaf area, seedling height, leaf pH, biomass, parenchyma and collenchyma cell thickness, lumen area of xylem vessels, stomatal conductance, and leaf relative water content were analyzed between shaded and sun-exposed light conditions. While stem and leaf biomass did not differ between the two light conditions, root biomass was 27% higher in the shaded than in the sun-exposed seedlings. Leaf pH was substantially lower in the shaded than in the sun-exposed condition. The vessel lumen area in both leaf and root was significantly larger in shaded than in sun-exposed condition by 10-15%. The parenchyma of seedlings in the shady area of the forest was thicker (c.a., 1-2 layers) compared to those in the well-lit environment, particularly in the leaf and root. While stomatal conductance was similar between the two light environments, shaded ones had a much larger leaf relative water content, up by 9-12%. Overall, we found significant morphoanatomical and physiological variations between shaded and sun-exposed seedlings, indicating invasive species' light-capture strategy and providing insights into S. macrophylla's invasive potential in the Philippines.

The protection effort of leopard cats (Prionailurus bengalensis Kerr, 1792) in the Upper Cisokan Pumped Storage, West Java, Indonesia. Biodiversitas 25: 169-176. Humans develop various infrastructures to meet electricity needs so that it is to improve human welfare besides the increasing population. Hydropower development cannot be separated from land clearing, which damages and eliminates the habitats of wild animals, including leopard cats (Prionailurus bengalensis Kerr, 1792). Humans also cleared land as agricultural land to fulfill their needs. Fulfilling the needs of electricity and agriculture is necessary to improve human welfare. Besides, leopard cats need a suitable habitat to meet their needs. Therefore, protection effort is required to fulfill leopard cats' and humans' needs. The study aims to reveal the protection efforts in the Upper Cisokan Pumped Storage, West Java, Indonesia. A qualitative approach was applied through literature reviews. The protection effort of leopard cats was conducted through stakeholder participation in the UCPS area. As the initiator, Indonesia Hydropower Company (PT. PLN) involves various stakeholders related to the construction of the UCPS hydropower plant, including Perum Perhutani, contractors, and the local people. Indonesia Hydropower Company (PT.

Abstract. Wijaya IMS, Sugiana IP, Astarini IA, Ginantra IK, Rahim KAA. 2024. Floristic composition of mangrove community in Ngurah Rai Forest Park and Nusa Lembongan, Bali - Indonesia. Biodiversitas 25: 300-309. The floristic composition of mangroves can be influenced by various factors, one of which is the size of the island. In Bali, Ngurah Rai Forest Park is one of the mangrove areas in the mainland of Bali, while Nusa Lembongan on the southeastern mainland represents the mangrove on the small island. This research aimed to study the floristic composition of the mangrove species in Ngurah Rai Forest Park and Nusa Lembongan based on the species diversity and the structure of mangrove community. Based on the explorative method, both locations have 20 true mangrove species cumulatively, with 18 species in Ngurah Rai Forest Park and 15 species in Nusa Lembongan. The mangrove community structure is majorly composed by Sonneratia alba and Rhizophora (R. apiculata, R. mucronata, and R. stylosa) in trees, saplings, and seedlings. Sonneratia alba has more impact in relative dominance, while the Rhizophora has more impact in relative density. Based on the Shannon-Wiener Index of Diversity, the mangrove community status is Moderate in both locations in all growth forms (trees, saplings, and seedlings). The Index of Dominance and Index of Evenness indicates the mangrove community is in stable condition with no extremely dominated species and fairly even species distribution. The mangrove condition is categorized as Good with Dense Trees based on the Decree of the Minister of Environment number 201 of 2004.

Abstract. Pasaribu DN, Rizali A, Tarno H, Priawandiputra W, Johannis M, Buchori D. 2024. Agricultural landscape composition alters ant communities in maize fields more than plant diversity enrichment. Biodiversitas 25: 205-213. Fragmented natural habitats in human-modified landscapes play a crucial role in conserving biodiversity. Ants, as keystone species, are integral to terrestrial ecosystems, making it essential to comprehend the factors influencing their survival. This study investigates the impact of agricultural landscape composition and plant diversity enrichment (flowering plants) management on shaping ant communities in maize (Zea mays L.) fields. The research occurred in maize fields surrounded by other crops, semi-natural habitats, and housing areas in Malang District, East Java, Indonesia. The four agricultural areas were divided into control and treatment plots, considering landscape composition parameters, particularly Class Area (CA) and the Number of Patches (NP), measured within a 500 m radius. The landscape around the maize fields was characterized by manually digitizing land use. Six types of plant diversity enrichment were employed in this study: wild cosmos (Cosmos caudatus), white buttercup (Turnera subulata), sunflower (Helianthus annuus), long bean (Vigna unguiculata), ornamental bean (Arachis pintoi), and coral vine (Antigonon leptopus). The study was divided into the dry season (April-July 2022) and the wet season (September-December 2022). Ant sampling was conducted using pitfall traps and, based on generalized linear models, revealed that plant diversity enrichment management did not affect species richness, abundance, or composition of ants. Landscape composition positively influenced ant species richness but negatively impacted species composition, particularly the number of semi-natural habitat patches. Maize crop age also positively influenced ant species richness but negatively affected beta diversity. Wet season was also found to have a negative effect on beta diversity. In conclusion, the proportion of semi-natural habitats in agricultural landscapes and crop age contribute significantly to species richness and species composition of ants.

Abstract. Bangun IH, Ketaren BR, Munar A, Sembiring P, Nurhajijah, Abdi A, Sitorus RS. 2024. Assessment of the dynamic growth and potassium solubilization capability of three novel bacteria. Biodiversitas 25: 177-185. Clay minerals are essential components that play a crucial role in soil cation exchangeable capacity and optimal plant growth. These components, including potassium (K), have the ability to bind with mineral crystals in the soil. Several studies have shown that K-solubilizing bacteria can facilitate the solubility of potassium, leading to optimal availability. However, the use of bacteria as biofertilizers is still limited due to challenges related to survival and growth patterns. To address these challenges, it is important to monitor the growth of the microbes and enhance their selection process to achieve effective utilization. Therefore, this study aimed to determine the bacterial growth dynamics and potential of Burkholderia paludis IHB_01, Burkholderia cepacia IHB_02, and Paraburkholderia phymatum IHB_03 in enhancing soil cation availability on clay minerals. The results showed a common initial adaptation phase among the 3 bacterial strains, followed by distinct exponential growth patterns. Burkholderia cepacia IHB_02 had the longest exponential growth phase, showing efficient resource utilization and extended growth. The results of soil cation enhancement by these bacteria showed that there were no major changes in measured parameters, such as total K, CEC, pH, and organic carbon. Furthermore, the variation in K exchange, organic carbon, and Na exchange provided insights into their unique interactions in the soil. The non-significant impact on potassium-related parameters in this study could be attributed to the presence of antagonistic cation interactions.

Abstract. Pasisingi N, Suci D, Panigoro C, Kadim MK. 2024. Morphological characteristic and truss morphometric analysis of amphidromous goby (‘nike') (Teleostei: Gobiiformes) in Bone River, Gorontalo, Indonesia. Biodiversitas 25: 223-231. One of the preferred fish resources in the Gorontalo region is amphidromous goby species, commonly known by local community as nike fish. In rivers, at the adult stage, these fish are morphologically and potentially morphometrically not necessarily distinguishable among species and between sexes. This research aimed to identify the morphological and morphometric truss characters that distinguish the sexual characteristics of goby fishes in the Bone River, Gorontalo. Fish samples were purposefully collected from eight sites along the river, spanning from upstream to downstream, using a backpack electrofishing device. Sampling occurred in March and November 2022, with morphological analysis and measurements conducted on 336 individuals. The morphometric method measured data from 13 points on the sample body, forming 28 combinations of truss distance characters (A1-A3; B1-B12; C1-C10; D1-D3) connecting these points. Morphologically, the samples were identified as three species, namely Sicyopterus longifilis, Belobranchus belobranchus, and Awaous grammepomus. This study revealed distinctions in morphological characters between male and female individuals. In S. longifilis, males exhibited a relatively slimmer body shape compared to the rounded form of females. Male B. belobranchus displayed more striking coloration than females, while male A. grammepomus featured a lighter brown body color than the paler females. All the morphometric truss characters in this study can be reliably used as a sexual distinguishing characteristic in S. longifilis. As for species B. belobranchus, B7 truss cannot be considered a differentiator. In A. grammepomus, thirteen truss characters (B3, B4, B6, B7, B8, B10, B12, C3, C6, C7, C9, C10, D1) cannot be used to differentiate males and females.

Morphological characteristic and truss morphometric analysis of amphidromous goby (‘nike') (Teleostei: Gobiiformes) in Bone River, Gorontalo, Indonesia. Biodiversitas 25: 223-231. One of the preferred fish resources in the Gorontalo region is amphidromous goby species, commonly known by local community as nike fish. In rivers, at the adult stage, these fish are morphologically and potentially morphometrically not necessarily distinguishable among species and between sexes. This research aimed to identify the morphological and morphometric truss characters that distinguish the sexual characteristics of goby fishes in the Bone River, Gorontalo. Fish samples were purposefully collected from eight sites along the river, spanning from upstream to downstream, using a backpack electrofishing device. Sampling occurred in March and November 2022, with morphological analysis and measurements conducted on 336 individuals. The morphometric method measured data from 13 points on the sample body, forming 28 combinations of truss distance characters (A1-A3; B1-B12; C1-C10; D1-D3) connecting these points. Morphologically, the samples were identified as three species, namely Sicyopterus longifilis, Belobranchus belobranchus, and Awaous grammepomus. This study revealed distinctions in morphological characters between male and female individuals. In S. longifilis, males exhibited a relatively slimmer body shape compared to the rounded form of females.

Abstract. Sadili A, Salamah A, Mirmanto E, Kartawinata K. 2024. Structure and distribution of palm tree species in Altingia excelsa planted forest in Gunung Gede Pangrango National Park, West Java, Indonesia. Biodiversitas 25: 249-256. Gunung Gede Pangrango National Park (GGPNP) is a conservation area consisted of natural forest and planted forest, including Altingia excelsa Noronha stands which were planted in 1925. As a result of secondary succession, various plants grow under Altingia excelsa stands, including palm tree species (Arecaceae). This research was conducted to determine the structure, population, and distribution patterns of palm trees in Altingia excelsa planted forest in Bodogol Resort, GGPNP. The data were collected by establishing a one-hectare plot divided into 100 subplots of 10 m × 10 m. Palm tree species with a Diameter at Breast Height (DBH) ?3 cm were measured, and the tree heights were estimated. Data analysis included Relative Dominance (RDo), Relative Density (RDen), Relative Frequency (RF), Importance Value Index (IVI), Shannon Wiener Diversity Index (H'), Evenness Index (E), Index of Dispersion (ID), analysis of variance values (S2) and Chi-square analysis (Q). The study results recorded four species from three genera of Arecaceae which consisted of 171 trees with a total Basal Area (BA) of 0.63 m2/ha. Pinanga coronata (Blume ex Mart.) Blume was the most dominant palm tree species with IVI of 156.89%), followed by Pinanga sp. (IVI=72.04%), Caryota rumphiana Mart. (IVI=55.77%), and Arenga pinnata (Wurmb) Merr. (IVI=15.38%). In term of diameter class distribution, Pinanga coronata and Pinanga sp. were regenerating well. Spatial distribution patterns of Arenga pinnata, Caryota rumphiana, and Pinanga sp. were regular, while Pinanga coronata was clustered. Periodical studies in the future to determine the mortality and natality of the palm trees are recommended to understand the dynamics of vegetation succession.
摘要Sadili A, Salamah A, Mirmanto E, Kartawinata K. 2024.印度尼西亚西爪哇Gunung Gede Pangrango国家公园Altingia excelsa人工林中棕榈树物种的结构和分布。Biodiversitas 25: 249-256.Gunung Gede Pangrango 国家公园（GGPNP）是一个由天然林和人工林组成的保护区，其中包括 1925 年种植的 Altingia excelsa Noronha 林分。由于次生演替的结果，Altingia excelsa 林下生长着各种植物，包括棕榈科（Arecaceae）植物。本研究的目的是确定圭亚那国家公园博多戈尔度假村 Altingia excelsa 人工林中棕榈树的结构、数量和分布模式。数据收集方法是将一块一公顷的地块划分为 100 个 10 m × 10 m 的子地块，测量胸径（DBH）为 3 cm 的棕榈树树种，并估算树高。数据分析包括相对优势度（RDo）、相对密度（RDen）、相对频率（RF）、重要值指数（IVI）、香农-维纳多样性指数（H'）、均匀度指数（E）、分散指数（ID）、方差分析值（S2）和卡方分析（Q）。研究结果记录了 Arecaceae 3 个属的 4 个物种，共有 171 棵树，总基部面积（BA）为 0.63 平方米/公顷。Pinanga coronata (Blume ex Mart.) Blume 是最主要的棕榈树种，IVI 为 156.89%），其次是 Pinanga sp.（IVI=72.04%）、Caryota rumphiana Mart.(IVI=55.77%)和 Arenga pinnata (Wurmb) Merr. (IVI=15.38%)。从直径等级分布来看，Pinanga coronata 和 Pinanga sp.Arenga pinnata、Caryota rumphiana 和 Pinanga sp.的空间分布模式有规律，而 Pinanga coronata 则呈集群分布。建议今后定期研究棕榈树的死亡率和原生率，以了解植被演替的动态。

Abstract. Yu Y, Liu H, Xu Z, Yan P, Wu H, Wu L. 2024. Analysis of the difference in endophytic bacterial community structure between infected and non-infected rice plants with rice bakanae disease. Biodiversitas 25: 197-204. Rice bakanae disease, caused by the main pathogen Fusarium fujikuroi, is an important fungal disease that seriously threatens rice production. This study analyzed the effect of Fusarium fujikuroi on the community structure and diversity of endophytic bacteria in different rice tissues. The total DNA of different tissues, such as root, stem, and leaf, was extracted after artificial inoculation, and the bacterial 16SrRNA gene library was constructed. The high-throughput sequencing was used to analyze the biological information of bacterial community composition, diversity and function. The results showed that a total of 467841 effective sequences were obtained. Alpha diversity analysis showed that the diversity and richness of the endophytic bacterial community in infected plants were higher than in non-infected plants. At the phylum level, Cyanobacteria, Proteobacteria, Firmicutes, Acidobacteria, Bacteroidetes, Chloroflexi, and Actinobacteria were the dominant phyla. The infection of rice seedling bacteria causes changes in the abundance of endophytic bacteria in rice. Compared with non-infected plants, the abundance of Streptophyta and Acidovorax in the root decreased by 1.29 and 0.74%, respectively. The abundance of Geobacter, Devosia, Pleomorphomonas, and Herbaspirillum increased by 1.05, 1.55, 1.28, and 1.76%, while the abundance of Streptophyta in stem decreased by 7.83%. The abundance of Xanthomonas, Acidovorax, Pseudomonas and Sphingomonas increased by 1.55, 1.49, 1.11 and 1.15%, whereas the abundance of Streptophyta in the leaf decreased by 12.03%, Actinomycetales, Pseudomonas, Sphingomonas are significant biological differences between different tissues of infected and non-infected plants. The study provides a theoretical basis for the biological control of rice bakanae disease.

Abstract. Hamdi MFFA, Ilyas S, Qadir A, Mayes S. 2024. Morphological variability and cluster analysis of 16 bambara groundnut (Vigna subterranea) genotypes. Biodiversitas 25: 97-106. Identifying morphological and germination characters in bambara groundnut (Vigna subterranea (L.) Verdc.) is important to determine the advantages and disadvantages of several genotypes. This study aimed to identify the characteristics of 16 bambara groundnut genotypes based on morphological markers, NDVI score, and germination variables. This study was conducted in Sumedang, West Java, Indonesia in March-July 2018. The experiment was arranged in a randomized complete block design with one factor: genotype, which consisted of 16 genotypes originating from Indonesia and Africa. The NDVI score did not affect the yield produced. Tiga Nicuru, DodR-R II, M-14 Gresik, Black Sukabumi, and Black Madura were the genotypes with the highest germination speed, while LunT was the lowest. Cluster analysis showed that bambara groundnut genotypes are classified into 4 clusters. The first cluster belongs to Sumedang and Sukabumi, the second belongs to Gresik, Madura, and Tasikmalaya, the third comes from West Africa (LunT and Tiga Nicuru), and the fourth comes from East Africa (IITA 686 and DodR-R II) and Southern Africa (S 19-3, Uniswa R and Uniswa R/G). The low similarity (28%) between genotypes from Indonesia and Africa shows that there are many differences in morphological characteristics. This high diversity is beneficial for creating superior cultivars.
