  • Correlations Between Fish Assemblage Structure and Environmental Variables
           of Taruwa Pond in Nawalparasi District, Province No. 4, Nepal

    • Authors: JASH HANG LIMBU, KESHI CHAUDHARY
      Pages: 1 - 8
      Abstract: The correlations between fisheries diversity and environmental variables of Nepal’s Pond are poorly understood. This study aims to investigate temporal variation of fish assemblage at Taruwa Pond in Nawalparasi district, Province no. 4, Nepal from October 2018 to April 2019. For the fish agglomeration, cast net of 4 kg in weight and 3.80 m in length and 22.5 m breadth with 12 mm mesh size was used. In total, 579 individuals representing 16 fish species, 10 families, and 12 genera were recorded. According to similarity percentage analysis, the most contributory species were Puntius ticto (27.92%) followed by Danio devario (12.06%), Puntius terio (9.76%), Badis badis (7.31%), Lepidocephalichthys guntea (5.57%) and Puntius sophore (5.57%). Analysis of similarity suggested that fish community structure was significantly different in temporal variation (R = 0.321, p<0.01). Based on the cluster analysis, fish assemblages were isolated into two distinct groups at Bray-curtis similarity. The Canonical Correspondence Analysis distinctly indicated that the water parameters of dissolved oxygen, carbon-dioxide, depth, and water temperature play an important role in influencing the fish assemblage structure of Taruwa Pond.

  • Gastropods in the Intertidal Shore of Kota Kinabalu, Sabah (Malaysian
           Borneo)

    • Authors: JOHN MADIN, BALU-ALAGAR VENMATHI MARAN, SUET-MUN HO
      Pages: 9 - 23
      Abstract: Intertidal gastropods provide numerous ecological benefits and are responsible for the dynamics of the intertidal shores habitat and its community assemblages. This study examined the community structure of gastropods in the intertidal shore located near the city of Kota Kinabalu, the capital of Sabah where coastal areas are rapidly developed for various purposes and consequently destroying natural habitats.  A total of 36 gastropods species from 15 families were recorded.  The Planaxis sulcatus was the most abundant species with a density of 480 ind. m-2 followed by Nodilittorina pyramidalis (182 ind. m-2) and Cellana radiata (97 ind. m-2) respectively.  The number of species and their abundance, respectively, are almost three times lower than the number ever recorded for intertidal shores located in non-urban areas or remote locations.  This suggests that the rapidly growing coastal urban areas threatening the diversity and abundance of intertidal gastropods. The density of gastropod (i.e. P. sulcatus & N. pyramidalis) was significantly (p<0.05) high at the lower intertidal shore where slope gradient is steeper with rocks and crevices are the major component of substrates compared to the upper or middle zone which is flatter and composed mainly of coral rubble and sand. Our study suggests that gastropod communities in intertidal shores located adjacent to the urban areas are threatened especially by anthropogenic factors such as frequent human visitations and modification of natural habitat. Future development in the intertidal shore should minimise habitat destruction and should consider infrastructures that encourage gastropod populations to grow and highlighting their ecological role for conservation reasons.

  • Fish Diversity and Water Quality Parameters of Mechi River, Jhapa,
           Province No. 1, Nepal

    • Authors: ASHIM ADHIKARI, JASH HANG LIMBU, SOMIKA PATHAK
      Pages: 24 - 34
      Abstract: Species diversity is widely recognised as an important trait of functioning and resilient ecosystem. Spatio-temporal patterns of fish community structure in the Mechi River was studied based on stratified random survey, conducted between September 2018 and April 2019. The survey was conducted at three different sampling stations in three different seasons. For the fish sampling, two cast nets of different sizes were used, one having large mesh size of 0.5 cm, 3 m diameter and 2 kg weight and another having mesh size of 2 cm, 6 m diameter and 6 kg weight. In addition, drag net and gill net were also used to collect the fish samples. A total of 1,772 fishes belonging to 4 orders, 8 families, 16 genera and 33 species were documented. The results from the similarity percentage analysis indicated that, the species Schistura devdevi, Brachydanio rerio, Puntius sophore, Barilius barila, Schistura beveani and Puntius terio were the most copious fish species recorded from the Mechi River. One-way analysis of similarity testing for space and time variations in fish community indicated that there was a significant difference in space (R = 0.66, p<0.01) but no significant difference in time (R = -0.0123, p>0.433). The Canonical Correspondence Analysis hinted that dissolved oxygen, water velocity and pH have shown to influence the fish assemblage structure in Mechi River.

  • Qualitative and Molecular Screening of Potential Ligninolytic Microbes
           from Termite (Coptotermes curvignathus) Gut

    • Authors: CARLINA FREDDIE SIMOL, JOHN KEEN CHUBO, PATRICIA JIE HUNG KING, KIAN HUAT ONG, CINDY CHEW, KHALID NAWI
      Pages: 35 - 42
      Abstract: Ligninolytic microbes have great potential in converting high lignin by-products to more utilisable products by decomposing the lignin-rich agricultural and industrial wastes. Thus, the aim of this study are to screen and identify the potential ligninolytic microbes from the termite (Coptotermes curvignathus) gut. The study was conducted at Universiti Putra Malaysia Bintulu Sarawak Campus, Malaysia. Twenty-seven microbes isolated from termite gut obtained from the Microbiology Laboratory, Faculty of Agricultural Science and Forestry, were used for the ligninolytic activity screening. Media with four different ligninolytic indicator dyes (Azure B, phenol red, methylene blue, and Remazol Brilliant Blue) were streaked with microbial isolates and incubated at 37 °C for 48 h. Out of twenty-seven microbe isolates, only three (CH2, CH5, and CH9) isolates showed decolourisation zone indicating the positive presence of ligninolytic activity. The 16S rRNA gene sequence data indicated the isolates are highly homologous to Bacillus spp.

  • Chemosystematic Evaluation of Some Nigerian Gossypium hirsutum L. Using
           Qualitative and Quantitative Phytochemical Analysis

    • Authors: DANZAKI MUHAMMAD MUAZU, MUSTAPHA OBA TOYIN, ABDULKAREEM KHADIJA ABDULHAMID
      Pages: 43 - 50
      Abstract: There is little information on the use of phytochemicals for the systematic study of variation and resolving relatedness in Nigerian Gossypium hirsutum species. Thus, there is a need to carry out detailed phytochemical studies of the plant leaves, which could be helpful in ascertaining their diversity and relatedness. The qualitative and quantitative phytochemical screening was conducted on 18 accessions of G. hirsutum using the established laboratory protocols. The findings of this study indicated the presence of tannin, alkaloids, proline, flavonoids, and saponin in all of the accessions that were grouped into two at 17% genetic distance, indicating 83% relatedness. However, phytosterol, terpenoids and glycosides were absent in three of the accessions, which were grouped at 48%. The phytochemical compositions were tannin (1.30-1.09 mg/100 g), flavonoid (1.60-1.16 mg/100 g, terpenoid (0.42-0.35 mg/100 g), alkaloid (1.47-1.11 mg/100 g), saponin (4.86-1.59 mg/100 g), glycoside (1.02-0.88 mg/100 g), proline (1.57-1.0 mg/100 g) and phytosterol (0.36-0.2 mg/100 g). The aim of this research was to determine the diversity and relatedness of G. hirsutum genotypes collected from different locations of Nigeria. In general, this study emphasises the use of plant chemicals for classification purposes.

  • Minimum Effective Dose of Chlorantraniliprole and Chromafenozide to
           Control Oil Palm Bunch Moth Tirathana mundella Walker

    • Authors: PATRICIA JIE HUNG KING, CHONG MING SU, YEE MIN KWAN, ZAKRY FITRI AB AZIZ, KIAN HUAT ONG
      Pages: 51 - 63
      Abstract: The bunch moth, Tirathaba mundella is one of the leading pests in oil palm estates established on peatland. Severely infested male inflorescences usually would fail reaching anthesis. Reduction in the number of inflorescences at anthesis stage would suggest less food source and breeding ground for oil palm pollinating weevils, Elaeidobius kamerunicus, thus, affecting the fruiting percentage of oil palm and its yield. Despite to be less detrimental to the environment, biopesticide usages in the field is losing favour due to its slower rate of kill compared with conventional chemical pesticides, shorter persistence in the environment and susceptibility to unfavourable environmental conditions. The use of high host specificity chemical pesticides, such as chlorantraniliprole and chromafenozide are gaining popularity in pest management regimes. In this study, the optimum dose for chlorantraniliprole and chromafenozide in controlling T. mundella was assessed to provide valuable information for sustainable oil palm pest management. Several dosages of pesticide were evaluated for their effectiveness against T. mundella in a 7-year-old oil palm estate for six months.   Based on the results obtained, application of 30 g or 40 g active ingredient (a.i.) per ha chlorantraniliprole were recommended to provide the longest protection period. To make plan for an effective pest management that could reduce material and labour cost per ha as well as the risks in developing pesticide resistance among pest, 30 g a.i per ha of chlorantraniliprole is recommended to be rotated with 25 g a.i. per ha chromafenozide for a total of four rounds in a year.

  • A Life Cycle Assessment (LCA) Approach on the Production of Sago Sucker
           for Cultivation

    • Authors: NAJWA SULAIMAN, NIK SASHA KHATRINA KHAIRUDDIN, MAIZAN ISMAIL, CHEE BENG YEOH , FARAH KHUWAILAH AHMAD BUSTAMAM
      Pages: 64 - 72
      Abstract: Sago palm is one of the commodities being cultivated and traded in Malaysia for its high starch content. Sago seedling, or commonly referred to as sucker, is the planting material for sago cultivation. This paper discusses the life cycle assessment approach for the calculation of life cycle inventory for the production of one sago sucker. In this study, the functional unit is defined as one sago sucker. The process starts from the reception of suckers from suppliers, raft preparation, planting sago suckers in rafts, fertilization, and ends with transportation of the suckers to the plantation. Interviews and data verification were done on-site at the Crop Research and Application Unit (CRAUN) Sungai Talau Research Station. LCI data showed that water was the main input for the production of sago sucker, followed by diesel for transportation, pesticides, and fertilisers. The outcome of this study provides a basis or guideline to planters in implementing sago best agricultural practices for the production of sustainable sago.

  • Factors Influencing the Natural Forest Regeneration at Khadimnagar
           National Park, Bangladesh

    • Authors: MAHEDI HASAN LIMON, SAIDA HOSSAIN ARA, MOHAMMAD GOLAM KIBRIA
      Pages: 73 - 83
      Abstract: Natural regeneration is an indicator of a healthy forest, hence, understanding the influence of site factors on natural regeneration is a significant concern for ecologists. This work aimed to assess the impact of site factors on natural tree regeneration at Khadimnagar National Park (KNP). Biotic factors (tree density, tree species richness, and basal area), physical factors (elevation, canopy openness), and soil properties (bulk density, moisture content, soil pH, organic matter, sand, silt, and clay) data were investigated from 71 sample plots to examine their effects on natural regeneration density and richness in KNP. Stepwise multiple linear regression analysis was done to predict both regeneration density and regeneration richness. The results showed that soil pH (p<0.001), canopy openness (p<0.001), tree species richness (p<0.01), and bulk density (p<0.01) had a significant effect on regeneration density, explaining 42% of the total variation. Regeneration richness was driven by four factors: tree species richness (p<0.01), soil pH (p<0.001), elevation (p<0.01), and canopy openness (p<0.01) with a model that explained 60% of the total variation. This study observed that soil pH, tree species richness, and canopy openness are the main controlling factors that influenced both the density and richness of regenerating species in KNP. Therefore, these findings have implications for natural resource management, especially in selecting suitable silvicultural systems in a tropical forest under protected area management where enhanced tree cover and conservation of biodiversity are needed.

  • Faunistic Study on Butterflies in the Lowland Forests of Central Surigao
           del Sur, Philippines

    • Authors: ARTURO GASCON GRACIA JR., LAURENCE PINGOL ALBIOS, ROMART LLOYD BALBUENA ALVERO
      Pages: 84 - 95
      Abstract: The province of Surigao del Sur is among the areas in the Philippines with limited wildlife studies, especially on lepidopteran fauna. Thus, this study was conducted to evaluate the butterfly congregation and diversity in Gamut and Mat-e, areas which are underexplored for lepidopteran surveys. It also aimed to assess the conservation and ecological status of the species. Sweep netting for a total of 196 person-hours was carried out to document the species. The results revealed a total of 29 species belonging to four families. Among the families, Nymphalidae was the most represented, comprising 48% of the total richness. The species Gandaca harina mindanaensis and Junonia hedonia ida were the most dominant in both sites representing 12% (each) of the total population. Species richness and diversity (H’) were relatively higher in Mat-e (n=22; H’=1.22) than in Gamut (n=15; H’=1.00). The total endemicity was 31%, but higher endemism was observed in Mat-e (36%) compared with Gamut (20%). The noteworthy findings are the listing of the nationally and globally assessed as rare species (Acrophtalmia leto ochine and Jamides celeno), but were locally assessed as common in Mat-e. One recorded butterfly (Atrophaneura semperi aphtonia) was assessed to be a threatened species. Based on the results, the two habitats showed a poor representation of butterfly assemblage, however, these results are highly affected by the limitations of the observation. Thus, it is recommended that an intensive study on butterflies in the area should be considered.
