This study aimed to identify the species variations in arthropod communities at different selected stations along Selangor River at two different sampling times. Present study was conducted for six consecutive months (August 2010 until January 2011) at 19 selected stations along the Selangor River. Sampling was conducted once per day and night. Sweeping method by using sweep nets were used as the arthropod sampling method. Data analysis was done quantitatively to determine the composition of arthropod community. A total of 7,707 individual arthropods collected belonging to 10 different orders consisting of Coleoptera, Hymenoptera, Diptera, Neuroptera, Orthoptera, Odonata, Lepidoptera, Blattodea, Mantodea and Araneae. A total of 4,563 arthropod individuals were sampled at night, which was more than the daytime (3,144 individuals), with Station 17 recorded the highest arthropod individual out of the 19 sampling sites. During the night, the firefly, that belongs to the Lampyridae family showed the highest arthropod composition. The presence of arthropod biodiversity along the Selangor River reveals that the S. caseolaris area is important in maintaining a diverse community of fireflies and other arthropods for conservation purposes.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45666390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although much has been studied on primate habitats and their diets, little is known about the nutritional value of the colobines’ foods. This study aimed to assess the dietary nutrient compositions of two sympatric colobine monkeys, Trachypithecus cristatus and Nasalis larvatus, in Bako National Park using proximate analysis of faecal, leaf and fruit samples of eight dominant tree species in Bako NP. Five nutrient parameters, namely crude protein, crude fat, crude fibre, ash, phosphorus, and energy content, were choosen to assess the nutritional demands of the monkeys in the wild.  The faecal samples showed significantly higher percentage of crude fibre (27.58%) in N. larvatus compared to T. cristatus. In contrast, crude fat (8.52%), ash content  (1.79%) and phosphorus (5.76 mg/g) were found to be significantly higher in the faecal samples of T. cristatus than in N. larvatus. The nutrient composition of leaves samples from the tree species consumed by N. larvatus and T. cristatus showed a significantly higher percentage of crude protein (14.56%) in Barringtonia asiatica (sea poison tree) and higher ash (13.70%) in Morinda citrifolia (Indian mulberry). Meanwhile, nutrient composition in fruit samples showed highest percentage of crude fibre (32.58%) and crude fat (12.35%) in Calophyllum inophyllum (Alexandrian laurel), whereas higher phosphorus (5.76%) and energy (24.26 KJ) were recorded in Ceriops tagal (Yellow mangrove). The higher crude fiber detected in N. larvatus’ faecal samples compared to T. cristatus  may indicates that N. larvatus experiences lower digestibility as they are incapable of completely digesting the tough leaves or fruits. This study provides useful information for the conservation and management of these primate species especially on their dietary requirements in captivity or in  a new habitat.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42866751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to identify the 1) proximate and mineral composition of banana, orange and watermelon waste powder subjected to different drying methods; 2) prebiotic potential of the fruit waste powder (FWP) in growth enhancement of the probiotic Lactobacillus casei. The fruit peels were processed by two methods: freeze-dried and oven-dried. All FWP was sterilised and milled into particle size <180μm. The proximate (total ash, crude protein, crude fat, crude fibre), mineral (Ca, Zn, Na, K, Mg, Cu) profiling was analysed in triplicate according to standard. Prebiotic activities of FWP were determined through the growth of L. casei analysed. Significant differences (p<0.05) result was observed between the proximate and mineral parameters in all FWP. Watermelon FWP had the highest moisture, ash, sodium, potassium, phosphorus, and zinc content, while banana FWP contained the highest crude protein, crude fat, and magnesium content. Both banana and watermelon FWP were found to exhibit high crude fibre content. The orange WP was reported with the highest carbohydrate, calcium, and copper content. Although significant differences (p<0.05) in composition were noted, the oven and freeze-drying methods employed showed no pronounced effect. Calcium, copper content (all FWP), sodium and phosphorus (watermelon FWP), phosphorus (banana FWP) examined highly exceeded the recommended dietary allowance (RDA) limit. Banana FWP showed the highest L. casei net growth of log10 8.28±0.02– 8.36±0.01 CFU/mL and 91.61–98.66% of survival rate, thus showing its potential as prebiotic agents among other FWP. All types of FWP showed significant difference (p<0.05) in bacterial growth except for oven-dried orange FWP. Overall, the results revealed that all these fruit wastes could be exploited for the nutrient and value-added potential in food formulations due to their inexpensiveness, natural, safe, and environmental friendliness.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41886117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was mainly focused on the analysis of habitat suitability of Rhinoceros unicornis in Nawalparasi, Chitwan, and Parsa districts of Nepal. The secondary data such as bioclimatic and topographical variables were collected from relevant sources. Spatial data were processed using various tools of ArcGIS while the presence data were converted using Excel, and analysis was done with Maxent. The results showed that approximately 75.17% (53.32 sq. km) of suitable area is occupied by Chitwan National Park. Similarly, Barandabhar Corridor Forest occupies 7.38% (18.89 sq. km) of the suitable area of the landscape. While, there is no area suitable for Greater One-horned Rhinoceros in Parsa National Park. Among Land Use Land Cover (LULC), the riverbed was found to be the most important variable. Invasion of invasive plants was found to be the most frequent disturbance factor followed by human disturbances and forest fires. Though grassland management is an important part of habitat management, it is highly recommended that the management of waterholes should be done. Protected Area manager should conduct localised habitat suitability assessment once the area is found suitable at the landscape level and further field verification should be done. Invasive plant control measures and alternatives to meet the forest product demand should be promoted.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44680383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current review aims to compile a checklist of fisheries resources in the Northwest Borneo (Sarawak, Malaysia) from available published literature, address the resources' present status, and suggest future monitoring needs for selected critical species. The study also aims to determine several Sarawak land-use issues that are in flux and responsible for habitat degradation. Five hundred sixty-four species belonging to 123 families and 32 orders were recorded from Sarawak waters. Freshwater fish species comprised 48.0% of the total, followed by a marine (36.6%), marine-euryhaline (12.9%), and brackish water (2.5%) species. Of this, Cyprinidae was the most dominant group accounting for the greatest number of species (82 species), followed by Balitoridae (34 species), Bagridae (21 species) and Penaeidae (21 species). Therefore, available fisheries resources should be managed carefully as 48 species (9.0%) are currently vulnerable to extinction. Furthermore, the presence of 20 alien species in Sarawak water bodies also requires attention from the authorities due to the potential disruption of aquatic ecological balance. Changing land use issues in Sarawak such as forest degradation, agricultural expansion, peatland deforestation and conversion, logging, destruction of mangrove forests, and construction of hydroelectric power dams and flood mitigation channels pose significant challenges to fishery management in Sarawak. Our study documents the priority of fishery monitoring and conservation in Sarawak water bodies to ensure sustainable management of fisheries resources.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46343226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six-week old C. gariepinus fingerlings with an average weight of 10.02 ± 0.2 g were stocked into three exposure sets (control, 2.75 ppm (25% of the 96 h LC50 value) and 5.50 ppm (50% of the 96 h LC50 value)) in triplicate at 30 fish per tank for 70 days. The 96 h LC50  value was 11.00 mg/L. Histological examination of the C. gariepinus exposed to various sublethal concentrations of glyphosate showed that major histological changes in their organs were concentration dependent such as gill arch vacuolation, excessive mucosal secretions, lifting of epithelial, and epithelium thickening, hyperplasia and telangiectasis in the gills, discolouration, change in form and consistent alterations involving hyperplasia, narrowing of the central nerve, necrosis, pkynosis, blood congestion and vacuolation of the liver, mild hyperplasia and inflammatory responses in the muscle of the fish. The severity of histological alteration was more pronounced in fish organs exposed to 5.50 ppm of glyphosate concentration. This study concluded that the toxicant (glyphosate) is highly toxic to C. gariepinus particularly at a concentration of 5.50 ppm, therefore its use near farm lands or adjacent water bodies should be discouraged.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46963179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, soil propagation of stem cuttings renders both the stem and developing roots susceptible to soil borne pathogens, ultimately compromising the quality of the plant. Good quality rootstock of the new plant promotes faster, safer, and better black pepper plant establishment. Hydroponic farming thus offers a good platform for producing quality rootstock of the new plants and has gained importance to many farmers due to its flexibility in manipulating plant growth conditions and timely pathogen management, thus safer, healthier, and faster growth. This study investigated the growing media suitable for rootstock growth of P. nigrum L. cv. ‘Kuching’ and compared the rooting ability between stem cuttings with adventitious roots at the time of planting and stem cuttings without any root at the time of planting. In a laboratory setting, a total of 210 stem cuttings were hydroponically planted in seven nutrient compositions, with each nutrient composition containing an equal number of stem cuttings with adventitious roots at the time of planting and stem cuttings without any root at the time of planting.

The early records of mud lobster were from Buntal in Kuching, and Lingga in Sri Aman back more than 130 years ago. A few other records were reported from the central and northern regions of Sarawak between 1928 and 2019. All these records have identified mud lobster of Sarawak as Thalassina anomala (Herbst, 1804). Our present study at two sites in Buntal area with a careful examination of morphological characters of fresh specimens has confirmed the taxonomy of the species and its existence in the area. Some ecological characteristics of the mud lobster, such as size variation, population density, and mound characteristics, are also discussed. The present study also found that construction of massive mounds by mud lobster has posed a conflict to farmers and coastal communities at Buntal area, who regarded the animal as a pest. On the other hand, research on the potential medicinal value of mud lobster in Sarawak is growing. This implies that accurate taxonomy and comprehensive ecological data of T. anomala are necessary to support best practices of mud lobster pest management and sustainable harvesting of the animal for medicinal purposes, which eventually lead to conserving the animal.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42705353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
