The population survey was done by direct observation with a random walk in the morning sun from 8 a.m. to 12 p.m., considering its appropriate months of appearance. There was no issue with counting repetition since this species appeared in single or double individuals at each locality of this survey. This work, which covered an elevation range of 550 to 2000 m, was carried out in central Nepal between May and July of 2017 and April, May, and September of 2018. A total count of 56 individuals of this butterfly was recorded in this survey, which covered adjoining districts like Bhaktapur, Lalitpur, Kathmandu, Makwanpur, and Nuwakot.\u0000The observed small population and distribution gaps of this butterfly in a few locations were primarily caused by habitat loss, the absence of sufficient plants that provide nectar for adults and food for larvae, and tourism activity, which was particularly noticeable in Nagarkot (Bhaktapur) and Chitlang (Makwanpur). In addition, the impact was seen primarily as a result of road construction, forest fires, and small landslides in some of its habitat areas in Makwanpur and Chandragiri.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45207851","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 Nepal bryophytes have been studied floristically in different parts of the country, but the impact of disturbance on floristic composition was lacking. Therefore, present study aimed to determine floristic composition of bryophytes especially on disturbed habitat generated by recently established Cable Car facility in Chandragiri hill, Kathmandu. The study area, highly disturbed at the base (1550-1600 m asl) and top of the hill (2400-2450 m asl), were selected for the collection of bryophytes. Altogether, 17 species of bryophytes including 5 liverworts, 11 mosses and 1 hornwort were recorded from the disturbed habitats. Among the 5 classes, Bryopsida was the most dominant class followed by the class Marchantiopsida, Polytrichopsida, Jungermanniopsida and Anthocerotopsida. Impact of elevation on diversity of bryophytes was observed in both sites of disturbed habitats. The diversity of bryophyte was found higher (13 species) at the base of the hill as compared to the top (8 species). Among the 17 species of bryophytes, 5 taxa (Aerobryidium filamentosum, Anomobryum auratum, Atrichum undulatum var. subserratum, Chiloscyphus profundus and Plagiomnium ellipticum) that have not been enumerated from the study site so far were also documented.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42211146","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 northern side of this district exhibits complex physical feature where this study was carried out within the elevation of 850m to 4300m. The changing elevation gradients along mountain habitats act to control the distribution of butterflies at its ascending range. This study made on different periods in 2009 and 2012 brought a list of 114 species of butterflies from three different destinations of the northern side that included areas like Melamchi, Timbu (central-northern), Helambu (northern) Nakote (north-western) Panch Pokhari and adjoining region (north-eastern). The diversity of butterflies declined gradually above 3500m towards Panch Pokhari whereas species richness was noticed high at 900-2700 m from Melamchi to Helambu route including Nakote, Shermathan and Tarkyghyang. Ecotourism promotional activity can also be linked to the butterfly watch that includes rare and attractive species carrying high interest to the visiting tourists to this region. These tourists intend to watch, document and photograph these butterflies besides birds and other wildlife species. The supplementary information on these insects including other faunal components can be helpful to provide impressive knowledge to the visiting tourists to this part.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41576931","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 experimental fishes were carried in the laboratory of Post Graduate Campus, Biratnagar. The visceral masses of the fishes were removed and examined under microscope by simple wet mount preparation for occurrence of various helminth parasites. Data were analyzed using SPSS version 16. C. orientalis (n=200) was infected by nematodes (Capillaria pterophylli), trematodes (Gonocerca physidis and Genarchopsis goppo) and cestodes (Senga sp.) giving prevalence of 87.5%. Similarly, C. striatus (n=225) was infected by nematodes (Camallanus intestinalis and Neocamellanus sp.), cestodes (Bothriocephalus sp.) and acanthacephalan (Pallisentis ophiocephali) with prevalence of infection 85.33%. The total multiple infection number was 131(74.9 %) found in C. orientalis. Channa spp. were heavily loaded by gastro-intestinal helminth parasites which may give rise to a health threat of zoonotic transmission to consumers. Therefore, immediate development of effective control measures and an application of good nourishment practice urgently needed to lower the helminth infection to fishes.","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":"46927914","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}

Fungal pathogens deteriorate the quality and quantity of tomato and cause health hazards to the consumers as well as economic loss to the traders. This study was carried out to identify some fungal diseases associated with post-harvest deterioration of stored tomato fruits in Balkhu Agriculture and vegetable Market of Kathmandu, Nepal. Collected samples were cultured in Potato Dextrose Agar (PDA) media in complete randomized design. Fifteen species of fungi namely Alternaria alternata, A. solani, Aspergillus niger, Botrytis cinerea, Fulvum fulva, Colletotrichum truncatum, Curvularia spicifera, Fusarium oxysporum, Dipodascus geotrichum, Mucor mucedo, Penicillium chrysogenum, Phytophthora infestans, Boeremia exigua, Pythium aphanidermatum and Rhizopus stolonifer were identified. These were responsible for 14 different diseases of Alternaria fruit rot, Anthracnose, Black mold rot, Botrytis Bunch Rot, Damping off/ fruit rot, Drechslera mold, Fusarium rot, Mucor rot, Penicillum rot, Boeremia blight, Phytophthora rot, Rhizopus rot, Russet, and, Sour rot.
