Plantation-grown, high-value timber species producing high-value end products are key to optimizing land utilization in Sabah and Sarawak states in Borneo, Malaysia, while meeting the demand for downstream processing. Eucalyptus pellita is one such species suitable for the tropical climatic...

Properties of Borneo sago starch reinforced poly-(lactic acid) (PLA) composites were evaluated, with attention to the effects of treatment with acrylic acid, benzene diazonium chloride, and tetrahydrofuran. The PLA-sago composites treated with tetrahydrofuran had the highest tensile strength, with...

Plantation-grown Eucalyptus pellita in Sabah, Malaysia, was analysed for compression and flexural properties to assess the potential for solid-timber and engineered wood product end uses. It is necessary to consider not only the volume of wood produced in a plantation but also the wood quality,...

The current study describes for the first time the chemical compositions and antimicrobial activity of essential oils from ironwood sawdust (Eusideroxylon zwageri) obtained from Borneo Island. Fifteen terpene metabolites were identified by GC-MS of the ironwood sawdust essential oil extracted by...

Gunung Palung National Park in Indonesian Borneo, home to 2,500 Bornean orangutans (Pongo pygmaeus ssp. wurmbii), suffers from severe deforestation that is caused by illegal logging. This article aims to analyze the success of an innovative entrepreneurship program in reducing illegal logging in...

Selective logging is very widespread across the tropics and can alter the habitat for myriad wildlife species. But while many studies have assessed the impacts of past logging on forest animals, far fewer have investigated how species respond to logging while the timber operations are actually...

Logging and forest conversion are occurring at alarming rates in tropical forests. These disturbances alter soil microbial community structure and functions. While direct links between changes in soil properties, such as pH and microbial community structure are well established, the indirect...

Old-growth tropical forests are widely recognized as being immensely important for their biodiversity and high biomass. Conversely, logged tropical forests are usually characterized as degraded ecosystems. However, whether logging results in a degradation in ecosystem functions is less clear:...

Tropical forest degradation affects host-parasite interactions, determining the probability of animals acquiring an infection. The activation of an immune response to fight off infections requires energy and other resources such as antioxidants which may be redirected from growth and reproduction....

Patterns of co-occurrence among species can help reveal the structure and assembly of ecological communities. However, studies have been limited by measuring co-occurrence in either space or time but not both simultaneously. This is especially problematic in systems such as masting forests where...
