Abstract
Hipposideros spp. are insectivorous bats and karst cave dwellers. This study aimed to study the roosting ecology, reproduction, and population fluctuations of three species H. diadema, H. larvatus, and H. ater in Gunung Sewu Karst region, Indonesia. Age and reproductive status of individuals were identified and analyzed using a combination of forearm length (FA) and body mass grades (W). Multiple regression analysis was used to determine the correlation read more

Abstract
The invertebrate indices for assessing water quality have not been widely developed in tropical regions where invertebrate diversity is generally high and severe water quality degradation is ongoing. We compared the applicability of six existing invertebrate indices using the dataset from 23 Indonesian streams and developed a new index by modifying an existing one using Threshold Indicator Taxa Analysis (TITAN). Analyses using general linear models (GLMs) revealed read more

Abstract
Privately owned forests (POF) play an important role in Indonesia’s social, economic, and environmental spheres. The success of optimizing their roles relies on the traditional management practices carried out by farmers. Therefore, this study aimed to explore POF traditional management by farmers, POF performance, and their influencing factors. Respondents included 170 farmers selected by simple random sampling and key informant. This study was conducted read more

Abstract
The rates of appearance of new mutations play a central role in evolution. However, mutational processes in natural environments and their relationship with growth rates are largely unknown, particular in tropical ecosystems with high biodiversity. Here, we examined the somatic mutation landscapes of two tropical trees, Shorea laevis (slow-growing) and S. leprosula (fast-growing), in central Borneo, Indonesia. Using newly constructed genomes, we identified read more

Abstract
LAI measurement using a direct method is time-consuming, while other instruments like Ceptometer, Hemispherical Photography, and LI-COR require high investment. This study aims to develop allometric equations for estimating the LAI of community forest tree species. Destructive sampling was conducted on 45 trees from three different species, i.e., Tectona grandis, Swietenia macrophylla, and Falcataria moluccana . The allometric equations were developed using read more

Abstract
Land limitation dramatically affects people with land-based livelihoods, such as farmers, and is often an obstacle to earning sufficient income for their family’s needs. Privately owned forests (POFs) are a land-based farming activity with a long history in Indonesian society. This study aimed to determine the socio-economic conditions, inequality, poverty, and livelihood dynamics of POF farmers. The research was conducted in three villages in Ciamis Regency, read more

Abstract
The devastating eruption of Mount Merapi, Indonesia, in 2010 resulted in the alteration of vegetation composition and structure across the exposed area, and it has been invaded by Acacia decurrens Willd. ever since. Nevertheless, A. decurrens provides a suitable agroecosystem for silvopasture, which has been considered the essential source of income for the society around Merapi. This research aims to observe the diversity and potential forage species under read more

Abstract
To evaluate the inheritance of natural durability of Acacia mangium Willd., wood-color parameters (Y [lightness], x [red to green], and y [yellow to blue]), mass loss by a white-rot fungus (Trametes versicolor) and brown-rot fungus (Fomitopsis palustris), and three different extracts (methanol extract, total phenol, and total flavanol content) were measured using the inner and outer heartwood of 10-year-old trees from 20 half-sib families in the third-generation read more

Abstract
Despite its considerable potential, oil palm trunk (OPT) remains underutilized, largely owing to the cyclical replanting process that occurs every 25–30 years. This study aimed to address this issue by developing an ecofriendly oriented strand board (OSB) using vascular bundles (VBs) from oil palm, both in binderless form and with the incorporation of natural adhesives made from sucrose and ammonium dihydrogen phosphate (ADP). The VB was extracted read more

Abstract
Increasing food demand and climate change-induced natural disasters pose significant challenges to food security. This study examines how forest conservation can mitigate disaster risks to agricultural land in Northern Thailand’s watershed. The Soil and Water Assessment Tool (SWAT) and Hydrologic Engineering Center’s-River Analysis System (HEC-RAS) models were used to assess flood impacts, while the standardized precipitation and evapotranspiration index read more
