Abstract
Teak (Tectona grandis) is a valuable tropical tree species that is widely planted in more than 65 countries, including extensive plantations on Java Island, Indonesia. Java plays a critical role in global teak production. However, few studies have assessed the genetic diversity and local adaptation of this species using genome-wide sequencing data across its natural distribution and Indonesian landraces. Analysis of genetic structure and local adaptation can
Abstract
Mangrove ecosystems are vital for human livelihoods, but ongoing exploitation and natural disturbances have led to significant land use and cover changes. Therefore, this study aimed to identify trends regarding land cover (LC) changes in mangrove ecosystems using remote sensing. LC changes from 1988 to 2024, as observedusing remote sensing techniques. Satellite imagery from Landsat 5 TM, Landsat 7 ETM+, Landsat 8 OLI/TRIS, and Landsat
Abstract
Peatland ecosystems play a critical role in conservation of biodiversity and climate regulation, but face ongoing degradation from land-use change, mining, and infrastructure development. In response, peatland restoration has gained global attention. This bibliometric study analyzed 448 publications from the Web of Science (1996–2024) to identify global research trends, influential contributors, collaborative networks, technological developments, and implementation
Abstract
Walikukun (Schoutenia ovata Korth.) is a commercially significant wood species in Indonesia. Heartwood, in particular, is important due to the natural durability and aesthetics, while lipophilic extractives play a crucial role in the formation. Therefore, this study aimed to determine the levels of lipophilic compounds in different radial positions associated with the formation of Walikukun heartwood. The results showed that the mean of n-hexane, methanol,
Abstract
This study investigates the effects of deforestation and climate change on water flow regulation within the mixed-deciduous-forest-dominated Upper Nan Watershed in Northern Thailand. Using the SWAT model, hydrological changes were analyzed under 16 land-use scenarios and CMIP5 climate projections (RCP4.5 and RCP8.5) for both historic (1980–2020) and future (2021–2080) periods. Findings reveal that increasing rainfall variability under RCP8.5 amplifies hydrological

Abstract
The optimization of land use under teak (Tectona grandis) stands in post taungya system canbe enhanced by planting understory crops in a kind of three-strata agroforestry systems.Despite the potential, there is limited information on growth, morphophysiological adaptability,production, and phenotypic plasticity of the crops. this study aims to assess growth,morphophysiological adaptation, biomass production, and phenotypic plasticity of Calliandracalothyrsus
Abstract
The Seed Production Area (SPA) of sandalwood (Santalum album L.) in East Nusa Tenggara is Indonesia’s sole designated site for sandalwood seed production. It was established 32 years ago using trees from six provenances on Timor Island. The SPA supports regional economies and ecological protection by producing high-quality seeds for commercially valuable trees and species conservation. Despite annual seed collection, information on reproductive status,

Abstract
To produce the next generation of Acacia mangium Willd. in Indonesia, radial variations of wood fiber and vessel element length, air-dry density, modulus of elasticity (MOE), modulus of rupture (MOR), and compressive strength parallel to the grain were investigated for 20 half-sib families of the third-generation trees. A radial variation modeling approach was applied to detect the differences in the radial variation of wood properties among families. In addition,
