    Ethnobotanical and ethnomedical knowledge of the Malays could be known either through oral sources or documented sources. The traditional sources of Malay medicine are useful for traditional and modern pharmaceuticals development in Malaysia and for conservation of biodiversity. This study aims to extract and categorise the ethnobotanical and ethnomedical contents documented in the medical chapter of Tajul Muluk, in the Malay ancient text. Transliteration and data extraction were carried out in order to identify and classify the information in the text. The manuscript has 292 medical interventions for 56 different diseases such as cough, fever, and mental health issues. There are descriptions available for different medical formulations using 209 plant-based materials, 12 animal-based materials and 40 other types. Many of the name and use of the materials are now rare or not well-known in modern today’s society. Medical descriptions listed in Tajul Muluk will be a documented proof of herbs used by local Malay population utilised as ethnobotanical and ethnomedical resources. Hence retrieving useful ancient documental knowledge should be explored in finding useful cures and alternatives therapeutics for various diseases.

    Differentiations in the habitat and resource utilisation lead to segregation and specialisation of niches for bats within the structurally complex tropical rainforest in Malaysia. This research aims to characterise chiropterans’ assemblages found in two different habitat types in Tasik Kenyir (dipterocarp forest) and Setiu (oil palm plantation). A total of 48 sampling nights were conducted within two years period from March 2017 to March 2019 which covered four sampling sites in Tasik Kenyir and four sites at Setiu. Two standard four-bank harp traps and 10 mist nets were deployed throughout the study at every site to capture bats at understory levels. This makes a total of 576 sampling efforts for both areas. Song Meter SM2bats and Echo Meter Touch from Wildlife Acoustic were used to record the echolocation of insectivorous bats. The total number of individuals and species observed were used to determine species diversity, richness, and evenness. Paleontological statistic software was used to generate the rank abundance and species accumulation curves. Bray-Curtis similarity index was used to generalise the index that represents the relative abundance of the sampling sites. A total of 835 individuals comprising 31 species from six families were captured at both study areas. Out of 835 individuals, 695 were captured within Tasik Kenyir comprising 27 species from six families (H = 2.381) while 140 individuals were captured in Setiu comprising 20 species from five families (H = 2.40). The diversity of bats in Tasik Kenyir was hypothesised to be higher than in Setiu as the habitat possess a larger undisturbed forest. However, the result showed the opposite in which no significant difference was detected from the diversity index calculated between these two areas. Detailed studies need to be conducted to determine if some areas are used as transient habitats for bats.

    The largest peatland in Malaysia is in Sarawak with approximately 1.66 million ha (13%) of total area, distributed widely in Sibu division followed by Sri Aman, Miri, Kota Samarahan, Sarikei and Bintulu. Despite being the most diverse animal species, the study of insects in peat swamp forest, particularly beetles, is still in the incipient stage. Therefore, this study aimed to provide recent information on the beetle species composition in a peat swamp forest of Real Living Lab, UNIMAS (RLL) located in Kota Samarahan. Beetles were sampled for five consecutive days and nights within a seven-day sampling trip in August 2020. Three sampling methods were employed in this study, namely handpicking method (HPM), modified Pennsylvanian light trap (MPLT) and pitfall trapping (PFT). A total of 15 families representing 37 species and morphospecies with 185 individuals were successfully collected. The most speciose family from the beetle assemblages in RLL is Scarabaeidae with eight species collected (21.62%), followed by Curculionidae with six species (16.22%) and Staphylinidae with five species (13.51%). The most abundant family was also represented by Scarabaeidae with 64 individuals (34.59%), followed by Scolytidae with 27 individuals (14.59%) and Carabidae with 23 individuals (12.43%), respectively. This suggests that these families are good candidates as biodiversity indicator of peat swamp forests. This study is still in its preliminary stage; hence it is important to conduct further beetle samplings in future to better understand the potential of beetle as a bioindicator in the peat swamp habitat as an effort to conserve and protect the habitat and the biodiversity that came along with it.

    Pre-diabetic is a disease that is caused by insulin resistance, which is identified by higher blood glucose levels than normal. Turmeric (Curcuma longa L.) contains curcumin compounds that act as antioxidants to prevent damage from free radicals and to repair damaged kidney tissue from pre-diabetic condition. Organic quail eggs are supplements that can help to repair kidney tissue. This study investigated the effect of turmeric powder and organic quail eggs on pre-diabetic kidney tissue histopathology of male white rats. Twenty-five male white rats (Rattus norvegicus L.) were used in this study and they were divided into 5 treatment groups, namely D0 (normal white rats were given standard diet), D1 (positive control, pre-diabetic white rats were given standard diet), D2 (pre-diabetic white rats were given turmeric powder 1.35 mg/head/day), D3 (pre-diabetic white rats were given 1 organic quail egg/head/day), and D4 (pre-diabetic white rats were given turmeric powder 1.35 mg/head/day and 1 organic quail egg/head/day). This research was done within 60 days. The results of the study were analysed using the ANOVA and Duncan tests. The analysis results showed that turmeric powder and organic quail eggs treatments had a significant effect on the observed parameters. The conclusion of this study is that the effect of turmeric powder and organic quail eggs has the potential to repair the kidney tissue of pre-diabetic white rats

    Brachyuran crab of Setiu Lagoon was systematically sampled between July 2011 and May 2012 to determine the community structure of animals and their relationship with environmental parameters. The semiterrestrial crabs were collected from a 100 m2 quadrat at eight stations. In addition, fishing devices were used to collect true aquatic crabs employed at the subtidal habitat. Forty-four species and 13 families were identified representing semiterrestrial and true aquatic crabs (i.e., Sesarmidae, Varunidae, Grapsidae, Ocypodidae, Macropthalmidae, Dotillidae, Camptandriidae, Pilumnidae, Portunidae, Eriphiidae, Oziidae, Dorippidae and Leucosiidae). Parasesarma plicatum, Perisesarma eumolpe, Clistocoeloma merguiense, Haberma sp., Uca (Austruca) annulipes, Uca (Gelasimus) vocans, and Moguai aloutos) were widely distributed in this lagoon. ST5 (at mix mangrove forest) recorded the highest number of species with density (12 ind.m-2), species richness (D = 2.68 ± 0.72), species evenness; (J’ = 0.90 ± 0.06) and species diversity (H’ = 2.17 ± 0.32) as compared to other stations. The results indicated that water salinity, pH and sediment grain size influence the community pattern of brachyuran in this lagoon.

    Special alcohols have been used as additives to study interfacial properties of cationic Gemini surfactant pentanediyl- 1, 5-bis (dimethyldodecylammonium bromide) (12-5-12). As these branched chain alcohols (in comparison with linear chain alcohols) are playing a measure roll in creating a microemulsion with Gemini surfactants. The surface tension values were measured by using ring detachment method. During the experiments, the ring was cleaned well by heating it in alcohol flame. The critical micelle concentration (cmc) values were obtained from surface tension (γ) versus logCt plots. The γ values decreased continuously and then become constant along a wide concentration range. The point of break, when the constancy of surface tension begins, was taken as the cmc of the system. Calculated Parameters are cmc, Гmax (maximum surface excess concentration), Amin (minimum surface area per molecule), C20 (the concentration of surfactant where the surface tension of the solvent is being reduced by 20 mN.m-1), (free energy of the given air/water interface), and the standard Gibbs energy of adsorption, ΔG­­0ads. An important property of micelle formation is the mean aggregation number which provides direct information about the general size and shape of the aggregates formed by amphiphiles in solution, and how these properties are related to the molecular structure of the amphiphiles. Mixed micellization behavior has been shown by these parameters. The mean aggregation number (Nagg­) of mixed micelles has been obtained by using the steady state fluorescence quenching method. Some other concerned parameters including dielectric constant (D), binding constant (KSV) were calculated in this study by using the ratio of intensity of peaks.

    Tree biomass equations are the most commonly used method to estimate tree and forest biomasses at various spatial and temporal scales because of their minor damage, ease of use, and high relative accuracy. The systematic compilation of models for the biomass of mixed evergreen and deciduous broad-leaved forest, a unique and essential class of typical vegetation types in the subtropical zone of China, has not been reported so far. In this paper, we compiled a species list through an inventory of 28.9 hm2 of mixed evergreen deciduous broad-leaved forests in southwestern Hubei Province with fixed detection sample plots, the species list was compiled by this study, and used it to retrieve, collect and establish a model dataset of woody plant biomass in subtropical mixed evergreen and deciduous broad-leaved forest. The species list contains a total of 665 biomass models in 167 groups. Each model corresponds to the plant species name, Latin name, plant life type, plant components calculated by the model, model independent variables, measurement units and ranges of independent variables, model correlation coefficient or coefficient of determination, and model sample size. is also recorded. By establishing this dataset, this paper not only provides essential information for in-depth research on the productivity and carbon sink of this specific vegetation but also provides a scientific basis for the management of this type of forest, the conservation of biodiversity, and the evaluation of forest ecological benefits.

    Heat treatment on commercial honey could deteriorate its quality associated with physicochemical and bioactive capacities. In this study, the effects of thermal treatment (50 °C, 75 °C and 90 °C) on the physicochemical properties (i.e., pH, colour intensity), total phenolic content and total flavonoid content were investigated on the Kelulut honey. The results revealed a significant increase in TFC (0.154 mg QE/g honey) for the heat-treated Kelulut honey compared to the control (0.085 mg QE/g honey). The antioxidant activity of the heat-treated honey revealed an increase in 2, 2- Diphenyl-1-picrylhydrazyl levels by 42%, while the ferric reducing antioxidant power levels were reduced significantly by 22.4% compared to the untreated honey. The antimicrobial activities of heat-treated honey declined against Staphylococcus aureus, Bacillus cereus, Escherichia coli, and Salmonella typhi bacteria at 75 °C and 90 °C. Based on the effects observed in the bioactive capacities of the heat-treated honey, it is therefore recommended to minimize thermal treatment on the honey during the processing to maintain its natural nutritional quality and benefit consumers.
