Abstract
The European Union (EU) established cooperation with timber exporting countries to fight illegal logging through the Forest Law Enforcement, Governance and Trade (FLEGT) Action Plan. FLEGT has gained increasing interest from several countries, including Vietnam, which has signed a bilateral Voluntary Partnership Agreement (VPA) with the EU. Central to the VPA is the implementation of a timber legality assurance system (TLAS) that ensures that only legal products
Abstract
With increasing replacement of native forests with agriculture, it is important to understand the factors allowing non-human primates to persist, including interactions with potential predators. For small-bodied nocturnal primates, smaller carnivores and domestic dogs that often characterise agroforestry landscapes may be a particular threat, especially for primates like slow lorises, which rely on canopy connectivity and are particularly vulnerable on the
Abstract
Population growth requires the use of more land, which increases land fragmentation. This study aims to understand the impacts and adaptation strategies of farmers facing privately owned forest land fragmentation (POF-LF). The research was conducted in Ciamis Regency, West Java, Indonesia. Data were collected through structured questionnaires for a simple random sample of 170 respondents, as well as in-depth interviews. The data obtained were processed by calculating
Abstract
Castanopsis argentea is an endangered tree naturally distributed in Java and Sumatera Island and considered a keystone species in the submontane forest ecosystem. A laboratory study was conducted to test the cross-amplification potential of seven pairs of Castanopsis cuspidata var. sieboldii microsatellite markers to be used for Castanopsis argentea. The rate of cross-amplification success, average number of alleles per locus (NA), observed heterozygosity (HO),
Abstract
Social forestry schemes aimed at both conservation and land redistribution for smallholders surrounding the Indonesian state forests. However, the results so far are mixed at best, with limited areas having been granted to the intended beneficiary groups. Several problems appear to be the causes. They range from the domination of administrative and managerial aspects of the scheme, lack of decision-making participation of the intended beneficiaries, to the
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
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
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
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
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
