Abstract. Setyawan AD, Sutarno, Sugiyarto, Sunarto, Dianti. 2025. Sustainability transitions and potential naturalization risk in the trade and cultivation of Selaginella kraussiana in tropical Indonesia. Asian J Agric 9: 925-945. Selaginella kraussiana has recently become popular as a tropical ornamental plant in Indonesia because of its attractive morphology, rapid vegetative growth, and suitability for humid shaded environments. However, information regarding the multidimensional sustainability of its cultivation and trade systems remains limited, particularly concerning ecological resilience, socio-economic performance, and potential naturalization risk associated with ornamental dissemination. This study evaluated the sustainability of S. kraussiana cultivation and trade systems in Central Java, Indonesia, using a RAPFISH-based multidimensional framework integrated with SWOT-TOWS analysis. Primary data were collected through semi-structured interviews, field observations, and environmental assessments involving 40 ornamental plant farmers and traders. Sustainability evaluation included ecological, economic, social, technological, and institutional dimensions. The ecological dimension achieved the highest sustainability index (83.93%), indicating highly sustainable cultivation conditions supported by humid microclimates and vegetative propagation systems. Economic sustainability was categorized as moderately sustainable (58.29%), whereas social sustainability remained low sustainable (36.70%). Technological and institutional dimensions showed unsustainable conditions (18.29%) due to limited innovation, weak institutional support, and low organizational integration. Monte Carlo validation confirmed strong RAPFISH ordination reliability with stress values below 0.25 and coefficients of determination (R²) above 0.94. The study indicates that increasing ornamental trade and repeated movement of vegetative planting materials may elevate propagule pressure and warrant precautionary ecological monitoring under favorable humid tropical environments. These findings highlight the urgent need for integrating ecological precaution, technological adaptation, institutional strengthening, and biodiversity conservation into sustainable tropical ornamental horticulture systems while minimizing potential ecological risks associated with ornamental dissemination.

Projecting expansion range of Selaginella zollingeriana in the Indonesian archipelago under future climate conditions. Biodiversitas 22: 2088-2103. The expansion of plant species to outside areas of its original localities has attracted great interest in theoretical ecology. The scientific curiosity of such phenomenon is even deeper when the geographical expansion is confined by natural boundaries and affected by environmental changes, including climates. This study aimed to predict the current suitable habitat niche of Selaginella zollingeriana Spring, a species with original distribution in Java Island, and to project its potential suitable niche in the Indonesian archipelago accounting for future climate conditions. In doing so, we applied the Ecological Niche Modelings (ENMs) using MaxEnt algorithm by employing 30 presence data of S. zollingeriana and twelve enviro-climatic variables. The model predicted around 17.22% (22,095 km2) of the Java Island area is potentially suitable for current habitat niche of S. zollingeriana, consisting of 10.93% (14,028 km2), 4.75% (6,097 km2), and 1.54% (1,970 km2) of low, medium, and high suitability areas, respectively. Under future scenarios, the model predicted the possibility of species expansion into the other four big islands (i.e., Sumatera, Borneo, Sulawesi, and Papua). Nonetheless, the model also predicted a declining trend of the availability of suitable niches wherein from 2030 to 2080 the modeled niche declined about 58% and 59% under the most optimistic and most pessimistic climate change projections, respectively. While this study provides a primary example in predicting species expansion in tropical archipelago, similar studies in a range of contexts (e.g., species, region) are recommended to add more evidence to strengthen the theoretical ground of expansion ecology under climate changes.

Abstract. Setyawan AD, Supriatna J, Nisyawati, Nursamsi I, Sutarno, Sugiyarto, Sunarto, Pradan P, Budiharta S, Pitoyo A, Suhardono S, Setyono P, Indrawan M. 2020. Anticipated climate changes reveal shifting in habitat suitability of high-altitude selaginellas in Java, Indonesia. Biodiversitas 21: 5482-5497. High-altitude ecosystems with humid and cool climate are the preferred habitat for some Selaginella species (selaginellas). Such habitats are available in Java, Indonesia, which also has fertile soils with rich mineral contents resulted from volcanic activities. However, the high-altitude ecosystems in Java are threatened by various anthropogenic activities as well as changes in climate conditions, potentially affecting some Selaginella species. This study aimed to investigate the shift in suitable habitat of four species of high-altitude Selaginella spp. (Selaginella involvens, S. opaca, S. ornata, and S. remotifolia) in Java Island under current and future climate conditions predicted by several representative greenhouse gas concentration pathways. Presence data of Selaginella localities were collected from field survey between 2007 and 2014 across the island, as well as occurrence points from the Global Biodiversity Information Facility database. A total of 1,721 occurrence points data along with environmental and climate data were used to develop species distribution models using MaxEnt. Future habitat distributions were projected under four climate scenarios to see the shift in suitable habitat and altitudinal ranges. The results showed that the distribution of the four high-altitude Selaginella species are strongly influenced by altitude, annual average temperature, and annual rainfall. In the present time, 37.32% (48,974 km2) of the area of Java has been predicted to be suitable for high-altitude Selaginella. Under the optimistic climate scenario (RCP 2.6), the highly suitable area will likely to decrease by almost 35% in the year 2080, whereas the medium and low suitable areas will reduce by about 37.2% and 18.3%, respectively. Under the pessimistic scenario (RCP 8.5), about 21.2% of low suitable areas will be lost in 2080, whereas the medium and highly suitable areas are predicted to decrease by around 38.1% and 33.4%, respectively. Under the pessimistic scenario, there will be upward shift by 51.1 m in the year 2030 from the current’s mean altitude and will shift by almost 150 m in the year 2080. The maximum altitude of predicted suitable habitat is also predicted to increase to reach almost 3500 m asl in the year 2080. The results of this study imply that habitat shift of four high-altitude Selaginella species varies depending on the scenario, but in all cases, the losses are greater than gains.

Abstract. Furqan M, Suranto, Sugiyarto. 2023. Population study of Cucurbita moschata based on morphological characters and isozyme banding patterns in Bima District, West Nusa Tenggara, Indonesia. Biodiversitas 25: 30-38. Pumpkin is a tropical plant that benefits from its lipid, protein, carbohydrate, and mineral contents. The morphological characters of pumpkins can be influenced by their genetics and environment. This research aimed to examine the relationship among 9 accessions of Cucurbita moschata Duchesne from 9 locations in Bima district, West Nusa Tenggara (NTB) province, Indonesia. The morphological characters of stems, leaves, and flowers were analyzed qualitatively and quantitatively and an ANOVA was used to look at the difference of leaf and flower characters. Polyacrylamide gel electrophoresis (PAGE) with peroxidase and esterase was used to detect isozyme banding patterns. Morphological characters and isozyme data were analyzed using a UPGMA method with NTSYS version 2.0 software to construct a dendrogram. The results show evidence of the varied morphological appearance of C. moschata from the different locations. A total of 12 esterase bands and 10 peroxidase bands were detected from Wera2. An undetected band with Rf value of 0.567 was recorded, while a unique band with Rf value of 0.133 (peroxidase) was not detected. Undetected bands with Rf values of 0.645 and 0.726 of esterase were also recorded.  A dendrogram showed three clusters of 9 accessions studied, in which Wera2 and Wera3 each stood alone, and a third large group was formed from the 7 remaining accessions. These results confirm the uniqueness of the Wera2 and Wera3 accessions. These results would be good information in determining a management strategy for improving the quality of pumpkins in the future.

Diversity of the medicinal plant in homegarden of local communities in the coastal area of Prigi Bay, Trenggalek, East Java, Indonesia. Biodiversitas 23: 6302-6312. Homegarden is a part of the agroforestry system that is essential in a food security program. It also reflects the social and traditional practices in certain areas that define the composition of plants. One common plant that grows in a homegarden area is herbal medicine. The knowledge about medicinal plants in society is essential to ensure the sustainability of this local wisdom to be passed through the subsequent generations. This research aimed to examine the diversity of medicinal plants planted in homegarden in Tasikmadu, Prigi, and Karanggandu Villages, Watulimo Sub-district, East Java, Indonesia. The research used a field survey of plant inventory and a semi-structured interview to gather ethnobotanical information. A total of 60 respondents were obtained by purposive sampling, with residents with homegardens preferred to be interviewed. The discussion results showed that 32 families of 59 medicinal plant species found in the study areas are consumed for medicinal purposes. Zingiberaceae is referred to as the highest family consumed by the respondents. Leaves and rhizomes are the most commonly utilized part, while decoction is the most popular preparation method. This study revealed that people aged 46-55 have the highest knowledge of medicinal plants. At the same time, women are considered to know more about herbal medicine compared to men.

Abstract. Yulia IT, Permatasari DP, Igustita, Berlin GE, Safira RN, Sugiyarto, Nazar IA, Himawan W, Sunarto, Pradhan P, Setyawan AD. 2023. Assessing the suitability of tree species for urban green space in a tropical university campus in Surakarta, Indonesia. Biodiversitas 24: 1713-1723. The presence of tree vegetation plays an important role in urban ecosystem. It provides various ecological and sociocultural functions from comforting micro-climates to beautification of the landscape. The central campus of Universitas Sebelas Maret (UNS) in Kentingan, Surakarta City, Central Java, Indonesia, has various tree species that grow well and become a constituent part of the campus area. This central campus environment has been considered one of the urban forests for city of Surakarta. This study aimed to determine the tree diversity occurring in the campus area of Universitas Sebelas Maret and to assess the suitability of the tree species based on silviculture, management and aesthetic aspects. Data collection was conducted by field observations at four stations: east, west, north, and south. Across the stations, the name of the tree species with minimum diameter breast height of 10 cm, the size of the tree’s circumference, the coordinates of the location of the tree, and tree’s morphological characteristics were documented. Each tree was then assessed for suitability for urban green space by scoring based on several silviculture, management and aesthetic criteria indicators. The results found 106 tree species in the studied area. Among them, 69 species (65%) had high suitability level, while 34 other species (32%) and 3 species (3%) were in the medium and low category, respectively. Some species with the highest score of 45 were kayu putih (Melaleuca leucadendra (L.) L), mimba (Azadirachta indica A.Juss.) and nyamplung (Calophyllum inophyllum L.), while the lowest score of 28 was kamboja (Plumeria acuminata W.T.Aiton). Species with high score are therefore recommended to be used in urban green space in the university area, and vice versa. The findings of this study suggest that vegetation suitability planning can be carried out to ensure the sustainability and balance of ecological functions of urban green space.

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. Negari SIT, Ningtyas SRA, Hanun Z, Sulton MN, Kusumaningrum L, Indrawan M, Sugiyarto, Sutomo, Setyawan AD. 2023. Agroforestry suitability evaluation using remote sensing in Jatiyoso Sub-district, Karanganyar District, Central Java, Indonesia. Biodiversitas 24: 6761-6769. Agroforestry systems are critical for biodiversity conservation, land degradation mitigation, and climate change mitigation. This agroforestry approach reduces forest degradation, boosts food security, and gradually raises farmers' income. This study uses remote sensing and Geographic Information System (GIS) modeling tools to analyze land potential and agroforestry status in Jatiyoso Sub-district, Karanganyar District, Central Java, Indonesia. The data used in the analysis support data for soil fertility index, rainfall, Shuttle Radar Topography Mission (SRTM) satellite image data, and Normalized Difference Vegetation Index (NDVI). Modeling was done by integrating various thematic layers in the GIS domain. Weighting was also carried out in the analysis of land suitability. The mapping results in Jatiyoso Sub-district, Karanganyar District, showed that 18.1% (13.49 km2) had high potential as agroforestry areas, 54.9% (40.95 km2) had medium potential, and 27% (20.18 km2) had low potential. As a result, using remote sensing and GIS to determine suitable land for agroforestry could significantly impact the community, particularly farmers, landowners, and foresters, in the decision-making process for developing agroforestry systems and practices and estimating important productivity indicators. The most promising and appropriate agroforestry plants developed in Jatiyoso Sub-district are medicinal plants, but agricultural commodities like cloves, bananas, and vegetables are also present.

Abstract. Setyawan AD, Chikmawati T, Miftahudin, Sutarno, Sugiyarto, Sunarto. 2026. Taxonomic reassessment of the Selaginella flora of Java, Indonesia. Biodiversitas 27 (2): d270239. https://doi.org/10.13057/biodiv/d270239. Selaginella Beauv. is one of the most taxonomically complex lycophyte genera in tropical Asia, and species delimitation in Java has long been complicated by extensive morphological variation, nomenclatural inconsistency, and contrasting taxonomic interpretations. This study provides a comprehensive floristic and taxonomic reassessment of Selaginella in Java based on 1,962 occurrence records from field surveys and herbarium collections. Species diversity, distribution patterns, and taxonomic relationships were evaluated using comparative morphology, ecological evidence, herbarium examination, and contemporary nomenclatural standardization. A total of 21 species are recognized, including 19 native taxa and two introduced or naturalized species (S. kraussiana and S. uncinata). Updated diagnostic descriptions and identification keys are provided, and several problematic taxa are reassessed. Selaginella ascendens and S. springiana are interpreted within the S. intermedia complex, whereas S. caudata and S. caulescens are treated within the S. plana and S. involvens complexes, respectively. Several vegetative characters traditionally used for species delimitation, including branch flattening, foliage density, and leaf overlap, were found to be highly variable and environmentally responsive, whereas stem pubescence, aristate leaf apices, and certain growth-form characteristics remain more reliable for identification. Floristic comparisons indicate strong affinities between the Javan Selaginella flora and other regions of Sundaland, particularly Sumatra and Peninsular Malaysia, together with secondary connections to Wallacea and the broader tropical and subtropical regions of Asia. The study provides an updated checklist, identification framework, and taxonomic baseline for future ecological, biogeographical, and evolutionary research on Asian Selaginella.

Abstract. Setyawan AD, Supriatna J, Darnaedi D, Rokhmatuloh, Sutarno, Sugiyarto, Sunarto, Kusumadewi Y. 2026. Genetic diversity and molecular differentiation among Javanese Selaginella revealed by SSR and ISSR markers. Biodiversitas 27 (5): d270520. https://doi.org/10.13057/biodiv/d270520. Selaginella is a highly diverse lycophyte genus in tropical Asia, yet molecular information for Indonesian taxa remains limited, particularly for evaluating species differentiation across geographically separated populations. This study assessed genetic diversity and molecular relationships among 32 Selaginella accessions representing eight recognized species and three unidentified taxonomic entities, collected mainly from Java, Indonesia, with additional materials from Bali, Lombok, and Papua. Genetic variation was analyzed using four SSR primers and five ISSR primers, which together generated 122 scorable loci, all of them polymorphic. SSR markers produced 43 loci, whereas ISSR markers generated 79 loci and contributed higher discriminatory power through greater polymorphism information content, resolving power, and marker index. Genetic similarity coefficients ranged from 0.42 to 0.93, indicating moderate to high molecular affinity among accessions. Both UPGMA clustering and principal component analysis consistently separated the major taxa, although widespread species such as S. plana and S. involvens showed moderate internal dispersion across accessions from different localities. AMOVA revealed that 80.1% of molecular variation occurred within species and 19.9% among species, with significant species-level differentiation (PhiPT = 0.199; P = 0.001). Nei's genetic distance revealed moderate molecular affinity among most Javanese taxa, whereas the Lombok and Papuan accessions occupied more divergent molecular positions. Geographic origin had little influence on the overall molecular structure, suggesting that species identity was the primary determinant of genetic differentiation. These findings demonstrate that combining SSR and ISSR markers provides a reliable molecular framework for refining taxonomy and supporting future conservation efforts for tropical Selaginella in Indonesia.
