DATA FROM: PHYSICAL PROPERTIES AND BONDING QUALITY OF LAMINATED VENEER LUMBER PRODUCED WITH VENEERS PEELED FROM SMALL-DIAMETER RUBBERWOOD LOG
DESCRIPTION : The peeling of small diameter rubber logs from the current short-rotation practices, undoubtedly will produced lower-grade veneers compared to the veneers from the conventional planting rotation. Hence, this raises the question of the properties of the produced laminated veneer lumber (LVL) from veneers peeled from small diameter rubber logs using spindleless lathe technology. Different thickness of rubberwood veneers were peeled from rubber logs with diameter less than 20 cm using spindleless lathe. Three layer LVLs were prepared using phenol formaldehyde (PF) adhesive and hot pressed at different temperature. During the peeling of veneer, lathe checks as deep as 30 to 60% of the veneer thickness are formed. This study showed that deep lathe check of 3 mm rubberwood veneer significantly reduced the gluebond shear strength of PF bonded LVL. In addition, lathe checks frequency were also shown to influence bond strengths. The presence of higher lathe check frequency on 2 mm veneer increased the wettability, thus, facilitated optimum penetration of adhesive for stronger bonding. These findings stress the importance of measuring and considering the lathe check depth and frequency during lamination process to get a better understanding of bonding quality in veneer-based products.

DATA FOR URBAN AND RURAL PREFERENCES TOWARDS WETLAND CONSERVATION USING SUBSIDY REDUCTION AS PAYMENT VEHICLE
DESCRIPTION : The preferences for wetland conservation among urban and rural dwellers in Malaysia estimated using a choice experiment. Wetland conservation alternatives were described in terms of environmental protection zones, biodiversity protection, recreational services and flood. Each alternative was connected to a cost for the household, which was a reduction in subsidies for daily goods. Using a latent class model, three groups were identified with distinctly different preferences. The results indicated potential conflicts over wetland conservation impacts and targets. Accordingly, the divide in preferences should be taken into account in policy-making, and the insights provided here may inform efforts to avoid conflict across the population.

DATA FROM: PRODUCTION OF BIOADSORBENT FROM PHOSPHORIC ACID PRETREATED PALM KERNEL SHELL AND COCONUT SHELL BY TWO-STAGE CONTINUOUS PHYSICAL ACTIVATION VIA N2 AND AIR
DESCRIPTION : In the present study, agricultural biomass; palm kernel shell (PKS) and coconut shell (CS) were used to produce high porosity bioadsorbent using two-stage continuous physical activation method with different gas carrier (air and N2) in each stage. The activation temperature was set constant at 600°C, 700°C, 800°C or 900°C for both activation stages with the heating rate of 3°C min-1. Two parameters including the gas carrier and activation temperature were determined as the significant factors on the adsorption properties of bioadsorbent. BET, SEM, FTIR, TGA, CHNS/O and ash content were used to elucidate the developed bioadsorbent prepared from PKS and CS and its capacity towards the adsorption of methylene blue and iodine. The novel process of two-stage continuous physical activation method was capable to emerge mesopores and micropores that were previously covered/clogged in nature, and simultaneously creating new pores. The synthesized bioadsorbents showed that the surface area (PKS: 456.47 m2 g-1; CS: 479.17 m2 g-1), pore size (PKS: 0.63 nm: CS: 0.62 nm) and pore volume (PKS: 0.13 cm3 g-1, CS: 0.15 cm3 g-1) were significantly higher than that of non-treated bioadsorbent. The surface morphology of the raw materials and synthesized bioadsorbent were accessed by SEM. Furthermore, the novel process meets the recent industrial adsorbent requirements such as low activation temperature, high fixed carbon content, high yield, high adsorption properties and high surface area which are the key factors for large scale production of bioadsorbent and its usage.

DATA FROM: PREDATION OF POTENTIAL INSECT PESTS IN OIL PALM PLANTATIONS, RUBBER TREE PLANTATIONS AND FRUIT ORCHARDS
DESCRIPTION : In human-modified landscapes, important ecological functions such as predation are negatively affected by anthropogenic activities, including the use of pesticides and habitat degradation. Predation of insect pests is an indicator of healthy ecosystem functioning, which provides important ecosystem services, especially for agricultural systems. In this study, we compare predation attempts from arthropods, mammals, and birds on artificial caterpillars in the understory, between three tropical agricultural land-use types: oil palm plantations, rubber tree plantations, and fruit orchards. We collected a range of local and landscape-scale data including: undergrowth vegetation structure; elevation; proximity to forest; and canopy cover in order to understand how environmental variables can affect predation. In all three land-use types, our results showed that arthropods and mammals were important predators of artificial caterpillars and there was little predation by birds. We did not find any effect of the environmental variables on predation. There was an interactive effect between land-use type and predator type. Predation by mammals was considerably higher in fruit orchards and rubber tree than in oil palm plantations, likely due to their ability to support higher abundances of insectivorous mammals. In order to maintain or enhance natural pest-control in these common tropical agricultural land-use types, management practices that benefit insectivorous animals should be introduced, such as the reduction of pesticides, improvement of understory vegetation and local and landscape heterogeneity.

APPLICATION STRATEGIES BY SELECTIVE MEDIUM TREATED WITH ENTOMOPATHOGENIC BACTERIA SERRATIA MARCESCENS AND PSEUDOMONAS AERUGINOSA AS POTENTIAL BIOCONTROL AGAINST COPTOTERMES CURVIGNATHUS
DESCRIPTION : The success of microbial termiticides in controlling termites depends on the ability of microbes to grow in different medium and the functionality of the microbes as a resistant barrier or toxic bait. This study was conducted to understand the mortality rate and behaviour changes of subterranean termite (Coptotermes curvignathus Holmgren) introduced with different concentrations of Serratia marcescens strain LGMS 1 and Pseudomonas aeruginosa strain LGMS 3 using wood and soil as bacterial transfer medium. In general, higher concentration of bacteria in soil caused reduction in tunnelling activity, wood consumption and an increased in mortality. However, application on wood revealed a different outcome. Wood treated with S. marcescens of 106 CFU/mL concentration proved to be more efficient as bait than higher concentration applications as it caused high mortality rate while still highly palatable for termites. Wood or soil treated with S. marcescens concentration higher than 109 CFU/mL creates a high toxicity and repellent barrier for termites. P. aeruginosa of 109 CFU/mL concentrations applied on wood served as a slow-acting toxic bait. However, the ability for S. marcescens and P. aeruginosa to survive on wood are low which caused the bait unable to retain a useful level of toxicity for a long period of time and frequent reapplication is needed.

MEASUREMENTS OF RIVER BED GRAVEL SAMPLES FROM THE SABETO RIVER, FIJI
DESCRIPTION : Bedload gravels were collected from seven stations along the length of the Sabeto River of western Viti Levu, Fiji. The Sabeto River is an active, bedload transporting, gravel-bed system (Gale et al., 2019). Sampling was confined to clasts of the distinctive and isotropic Navilawa Monzonite, an intrusive rock that crops out only along the upper reaches of the river (Rao, 1983; Hathway, 1993). The river has entrenched the Navilawa Monzonite outcrop resulting in the direct supply of monzonite gravels to the fluvial system. Bedload gravels were collected along transects at seven stations (1 to 7) over a distance of 9.7 km. One of the sampling sites was located above the downstream boundary of the monzonite outcrop, the rest below. In addition, samples of fresh Navilawa Monzonite undergoing active physical breakdown were collected from alongside the bedrock channel at Station 0. The shape of these clasts provides us with the opportunity of observing the nature of the precursor particles as they are liberated from the rock and before they experience fluvial modification. The density of the fresh Navilawa Monzonite was estimated. A total of 883 particles, ranging in diameter (b-axis) from 12 to 337 mm, was collected. The long (a), intermediate (b) and short (c) axis of each particle was measured, along with the diameter of the sharpest corner of the maximum projection outline (Di) and the diameter of the maximum inscribed circle (Dk). At six of the stations, the mass of each particle was recorded. The dataset includes calculations of the Modified Wentworth Roundness, Maximum Projection Sphericity and Oblate–Prolate Index of each clast. At six of the stations the volume of each particle was estimated using measurements of particle mass and the density of the fresh Navilawa Monzonite.

HABITAT FRAGMENTATION AND LOGGING AFFECTS THE OCCURRENCE OF THE LESSER MOUSE DEER IN TROPICAL FOREST RESERVES
DESCRIPTION : Due to rapid urbanization, logging, and agricultural expansion, forest fragmentation is negatively affecting native wildlife populations throughout the tropics. This study examined the effects of landscape and habitat characteristics on the lesser mouse deer, Tragulus kanchil, populations in Peninsular Malaysia. A total of 315 camera traps were deployed in eight forest reserves. This study provides critical ecological information for managing and conserving understudied populations of T. kanchil. We found that the detection of T. kanchil was attributed to forest fragmentation. Forest patches had the detection of T. kanchil four times greater than continuous forests. The detection of T. kanchil was nearly three times higher in the peat swamp forest compared to the lowland dipterocarp forests. Surprisingly, the detection of T. kanchil was almost twice lower in the unlogged forests compared to logged forests. The detection of T. kanchil increased with the presence of trees, particularly those with DBH of 5 cm to 45 cm, canopy cover, number of saplings and palms, number of dead fallen trees, and distance from nearest roads. However, detection decreased with a greater number of trees with a DBH greater than 45 cm and higher elevation. We recommend that conservation stakeholders take the necessary steps to support the conservation of mouse deer species and its natural habitats regardless of whether these forests are fragmented or continuous. These steps include eradicating poaching, habitat degradation, and further deforestation.
