The population structure and estimated populations along with their habitat using direct observation and the branch estimation method were assessed. The general behaviour of the individual animal was observed and recorded using focal animal sampling over a 10 minute periods either in the morning or evening. Local people and members of the Nepal Army were interviewed using semi-structured questionnaires in order to assess threats.\u0000Most flyng fox were found roosting in tall Eucalyptus spp. trees and the highly branched Populus spp. Resting was observed as the most the dominant behavior among male, female and young individuals during the study period. Highest populations (n=1421) were observed in September 2016 and lowest (n=36) in February 2017. Habitat destruction, lack of food, urbanization and electrocution were the major threats to P. giganteus. The population is decreasing compared to previous studies. Electrocution and persecution by humans are the major causes of accidental death each year. Therefore, in order to conserve and save this species, habitat and afforestation along with awareness programs should be implemented urgently.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44192939","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}

Conservation and management planning of wetlands requires, among others, a comprehensive floristic account. In this study, we prepared a checklist of the flowering plants found in the wetlands of the Lake Cluster of Pokhara Valley (LCPV), a Ramsar site of Nepal, located in a rapidly urbanizing capital city of Gandaki Province in Central Nepal. Voucher specimens were collected from the study sites through multiple visits during the monsoon (June-August) and autumn (September-November) seasons. Species were categorized based on their life forms (Raunkiaer’s classification) and native distribution range (native, naturalized, invasive). Ethno-botanical uses of the plant species were compiled from the published literature. We identified 230 plant species belonging to 70 families and 177 genera. Asteraceae (25 species), Poaceae (22 species), Fabaceae (18 species), Cyperaceae (16 species), and Lamiaceae (11 species) were species-rich families. Therophytes (30%) were the dominant life form followed by Hemicryptophytes (27%). Among 230 species, 183 species were native and 47 species naturalized; among the naturalized species, 21 species were invasive. Most of the plant species (61%) have medicinal values while others have food (24%) and fodder values (13%).","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41703287","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}

In recent years, natural antioxidants are being explored intensively for their ability to protect organisms and cells from oxidative stress-induced harm. Furthermore, mushrooms are widely used as a source of natural therapies for a variety of ailments caused by oxidative stress. In this study antioxidant activities of Morchella conica Pers. extracts obtained with methanol were investigated. This is supposed to be the first report of the antioxidant activity of morel mushroom from Nepal. Five complimentary test systems; namely DPPH free radical scavenging, total phenolic compounds, total flavonoid, ascorbic acid, and carotenoid concentration were used. At concentrations of 12.5, 25, 50, 100 and 200 μg/ml the methanol extracts scavenged 69, 69, 70, 68 and 81% DPPH radicals. The total phenolic content of the extracts was 4.304±0.12 mg/g gallic acid equivalent. The total flavonoid compound concentration was measured as 0.381±0.00 mg/g quercetin equivalent. The concentrations of ascorbic acid were recorded 19±0.02 mg/g dry sample. β-carotene and lycopene detected in the extract of M. conica are 0.020±0.001 and 0.021±0.002 μg/ml respectively. Finally, the findings of this study demonstrated that M. conica has a high antioxidant activity, making it potentially effective in antioxidant therapy and therapeutic intervention in oxidative stress-related disorders.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43597453","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 evaluate ground water quality of the Kathmandu valley. In this study, the physio-chemical parameters of water samples were performed using standard procedures. Also, total coliforms were enumerated using standard membrane filtration technique to quantify the bacterial contamination. Water samples were collected from July 2017 to July 2018. The results revealed that 56% and 73% of well and boring water samples, respectively exceeded standard value of iron recommended by National Drinking Water Quality Standards, 2005. Likewise, ammonia content was higher in 41% of well water and 35% of boring water samples than standard. However, few numbers of water samples were contaminated with arsenic (0.27% and 2.6% of well and boring water samples, respectively) and nitrate (3% and 8% of well and boring water samples, respectively). Besides, 96% of well water samples and 88% of boring water samples were contaminated with total coliform bacteria. Our data indicated that groundwater quality of Kathmandu valley was poor, which was not suitable for direct drinking purposes. Therefore, regular monitoring and treatment of groundwater is recommended before using accordingly.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48893743","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 carried out with an aim of documenting the flowering plant diversity of the Panchase Protected Forest, Kaski district, comprising three VDCs, Bhadaure Tamage, Chapakot and Pumdi Bhumdi. General survey, covering all seasons was organized (from June 2014 to May2015) for collecting the plant species. Published literatures and herbarium specimens were also consulted for documenting the species. Identification of the collected specimens was made through consulting relevant literatures, herbarium specimens and expert consultation. A total of 613 species belonging to 393 genera and 111 families have been documented from this area. The dominant family was Orchidaceae (49 genera and 125 species) followed by Poaceae (25 spp.), Asteraceae (25 spp.) and others. Six endemic plants, Begonia flagellaris (Begoniaceae), Eria pokharensis, Gastrochilus nepalensis, Oberonia nepalensis, Odontochilusnandae and Panisea panchaseensis (Orchidaceae) were also reported. Similarly, presentresearch revealed two taxa as new record for flora of Nepal, Dischidia bengalensis Colebr. (Apocynaceae) and Phreatia elegans Lindl. (Orchidaceae). The present findings suggest that PPF is one of the hotspot for floral diversity representing mid hills of Nepal and this pristine habitat for orchid should be developed as ‘Orchid Sanctuary’.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3126/jnhm.v30i0.27538","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47806417","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}

For the study of stomatal complex of leaf, Carpenter’smethod was followed. Stomatal index and stomatal frequency were calculated using formulagiven by Salisbury. The terminologies used for the stomatal complex type were followed those of Patel. In all species the leaf surface was found hypostamic. Tetracytic (a-tetra-monocyclic,b-tetra-monocyclic and c-tetra-monocyclic) and eupara twi-monocyclic with hexa-monocyclictypes of stomata were recorded in the genus. Tetracytic type was found in fourteen species and eupara twi-monocyclic with hexa-monocyclic was found in only one species. The elliptical shape of stomata was found in more species than the circular shape. The epidermal cells of leaf was found rectangular, square, polygonal to irregular. The distribution of stomata on leaf surface, type of stomata and shape of epidermal cells were found to be taxonomically significant. These characters could be used as distinguishing characters to delimit the species in the genus.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3126/jnhm.v30i0.27400","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45987707","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}
