Species radiations, despite immense phenotypic variation, can be difficult to resolve phylogenetically when genetic change poorly matches the rapidity of diversification. Genomic potential furnished by palaeopolyploidy, and relative roles for adaptation, random drift hybridisation in apportionment remain understood factors. Here, we study these aspects a model radiation, Syzygium, most species-rich tree genus worldwide. Genomes 182 distinct species 58 unidentified taxa are compared against...
Exposure to UV/infrared (IR) radiation is the main extrinsic factor that changes skin morphology and affects increase in reactive oxygen species (ROS) aging. Ten varieties of andaliman (Zanthoxylum acanthopodium DC.) fruit are presumed have anti-aging compounds via an enzyme-inhibition mechanism. This study aims compare ten essential oils (EOs) varieties, group them according their obtain chemical components can be used as potential agents using molecular docking. EOs were isolated by...
Shorea is one of the largest genus in Dipterocarpaceae with 194 species world, ±160 originated from Malesia region and consisted ±125 Indonesia. population which grown Indonesia have high economic value wood. Distribution would be affected by some factors especially edaphic, climate, altitude. Based on observation speciment collection Herbarium Bogoriense, were highest distributed 0-500 m 500-1000 altitude Dipterocarps forest type. Borneo (102 species) Sumatera (52 species)islands habitat...
Abstract The island of Sulawesi formed from the joining proto‐islands roughly three million years ago. Regions zoological endemism, corresponding to proto‐islands, have been reported. Sulawesi's tree communities, however, remain poorly documented. In better‐studied tropical regions, soil types similar those found in often distinctive communities. To gather data on we established ten (0.25 ha) plots four across regions. We documented diversity, dominance, and species composition. Linear...
Tropical forests occupy small coral atolls to the vast Amazon basin. They occur across bioregions with different geological and climatic history. Differences in area bioregional history shape species immigration, extinction diversification. How this effects local diversity is unclear. The Indonesian archipelago hosts thousands of tree whose coexistence should depend upon these factors. Using a novel dataset 215 forest plots, fifteen islands ranging from 120 785 000 km 2 , we apply Gaussian...
Abstract Background and aims Ultramafic soils have high metal concentrations, offering a key opportunity to understand if such metals are strong predictors of leaf stoichiometry. This is particularly relevant for tropical forests where large knowledge gaps exist. Methods On the island Sulawesi, Indonesia, we sampled on sand, limestone, mafic ultramafic that present range soil concentrations. We asked how variation in 12 elements (metals macronutrients) influenced stoichiometry whether...
The Indonesian island of Sulawesi possesses a biota defined by anomaly (Wallace 1869). It has high levels endemism (Michaux 2010) but, despite attracting research interest since the time biogeographic pioneers such as Alfred Russell Wallace, remains relatively undocumented (van Welzen et al. 2011) with collection rates below much wider region (Kessler 2002). As currently known, flora suggests placement within Austral-Asian amalgamative Wallacea, which encompasses chain islands between Borneo...
Abstract The Sumatra forest was estimated with high biodiversity and the second largest rate of deforestation after Kalimantan. However, research about monitoring dynamics around Lake Toba are still unknown. aim this is to obtain information changes in structure composition mountain Region during 2018-2019. Vegetation survey old secondary Region, North covers 0.9 ha area using 30 x 30m totalling 10 plots had been conducted three villages, i.e., Jangga Dolok, Ambar Halim Halado. results...
Andaliman (Z. acanthopodium) is an aromatic Non-Timber Forest Product (NTFP) plant species that contains essential oils (EOs), which have various benefits for cuisine, medicine, and cosmetics. This study because it not yet known what biotic factors (basal area) abiotic (soil elevation) influence the EOs yield, geranyl acetate, D-limonene as skin anti-aging. investigated whether basal area, soil, elevation content of fruit. The were measured from 9 sample plots representing habitats in North...
Abstract Species radiations have long fascinated biologists, but the contribution of adaptation to observed diversity and speciation is still an open question. Here, we explore this question using clove genus, Syzygium, world’s largest genus tree species comprising approximately 1200 species. We dissect Syzygium through shotgun sequencing 182 distinct 58 additional as-yet unidentified taxa, assess their genetic against a chromosome-level reference genome sea apple, grande. show that grande...
The area within Pusbindiklat Peneliti-LIPI (The National Training and Education Center for Researchers Development-Indonesian Institute of Sciences) has been planted with many trees as an effort reforestration increasing aesthetic value. Unfortunately, the management paid less attention to potency its characteristic well inventorizing all trees. This study aim inventorize tree species based on their morphological in order know concerned safety. Research was conducted through scoring...
Andaliman (Zanthoxylum acanthopodium) plant, a unique spice in the Batak tribe limited only to fruit. The leaves available most of time and consisting essential oils, there are no research has been conducted on molecular docking determine potential drug. Covid-19 pandemic is still ongoing, so information as Corona antivirus needed. This study aims find differences chemical components from oil, classify varieties, get antivirals based docking. were collected North Tapanuli District, than...
Ekosistem hutan di Danau Toba mempunyai peran penting bagi masyarakat dan lingkungan sekitarnya. Kajian dinamika hara dilakukan sebagai upaya mempelajari melestarikan ekosistem Toba. Penelitian ini bertujuan untuk menganalisis biomasa serasah lantai serta kandungan tanah hutan. Desa Jangga Dolok, Ambar Halim, Halado (Kabupaten Toba) Siulakhosa Samosir) menggunakan petak pengamatan berukuran 30 x m. Pengambilan contoh secara diagonal pada 3 titik subpetak setiap dengan ukuran 50 cm kedalaman...
Mount Gandang Dewata in West Sulawesi was recently granted National Park status. Exploration of land snails Taman Nasional (TNGD) has never been carried out. Therefore, a study the conducted April 2016 to examine composition different habitats, namely primary and secondary forests. Overall, 43 specimens (21 species from 8 families) were found eight sites. Snails are not steep areas, on moderate slopes 1-10 found, flat areas 8-13 found. The analysis out by principal components (PCA)....
