It is reported from different places in Nepal, particularly from mid-hill areas. However, the ecology and ethnomycology of L. sulphureus were poorly known in Nepal. We aimed to study the ecology, ethnomycology, and present status of L. sulphureus from the mid-hills of Dolakha district, central Nepal. The habitat of L. sulphureus in the six different sites of the study area was surveyed to find out the dominant tree species and microclimatic conditions. Additionally, a questionnaire survey was conducted to document ethnic knowledge and the status of L. sulphureus. We found dominance of tree species such as Tsuga dumosa, Quercus semicarpifolia, and Rhododendron arboreum in the habitat of L. sulphureus. Dead and decayed logs/trunk of these tree species were found to support L. sulphureus growth. Regarding microclimatic conditions, an average temperature of 20 °C, a light intensity of 1000–2000 lux, and relative humidity of 65–80% were recorded under the canopy where L. sulphureus was growing. Fruitbodies of L. sulphureus were found to be collected by local people for food and medicinal purposes. Local people were found to use dried L. sulphureus powder for the treatment of aliments such as diarrhea and hematochezia. The availability of L. sulphureus was found to be declining due to overharvesting, logging of the host tree, and the removal of coarse wood debris. Collection of L. sulphureus fruitbodies and logging of host tree should be regulated for its conservation in wild habitat. This study provides valuable information about the possible substrate types and environmental conditions that could be used for the successful domestication of L. sulphureus at the study sites and similar locations.","PeriodicalId":19905,"journal":{"name":"Our Nature","volume":" 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141676454","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 majority of the sampling locations were chosen along the treks from Lukla to Everest Base Camp, Gokyo, and Imja valley. Chemical parameters, such as total nitrogen and total phosphorous, were studied in the ecology laboratory of Central Department of Botany, Tribhuvan University, while physical characteristics such as pH, temperature, total dissolved solids (TDS), and conductivity were assessed on the spot by water analyzer kit Although water quality standards still meets the WHO's and Nepal's standards for drinking water, the quality of the spring water is starting to deteriorate. On the main tourist treks, Changes in water quality metrics in water bodies have been observed. Each year, the values of total nitrogen (TN-NO3), total phosphorous (TP-PO4), and pH change, indicating a decline in the quality of the springs water bodies in the Sagarmatha National Park and Buffer Zone (SNPBZ). The values of TN-NO3 and TP-PO4 had significantly increased, indicating that human impact had also increased. Although the amount of total nitrogen in water samples was lower than the WHO limit, there has been an increase in nitrate-nitrogen as compared to past findings. Similar to this, it was discovered that the total phosphorus value increased both annually and in earlier reports. Therefore, sufficient care should be taken to stop future deterioration. The research produced a database for the current state of Nepal's highland springs, which may be used to manage the springs and research how human activity affects water quality.","PeriodicalId":19905,"journal":{"name":"Our Nature","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141673903","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}

Bees get enough choices to forage in an agro-ecosystem study area. Flowering plants visited by honeybees were observed and documented as per their preferences of foraging, distance away from the bee-hive and seasons. Each plant enlisted as bee-flora if a honeybee visited any flower and rested at least for a while. A total of 168 vascular plant species documented as bee flora in this study. These flora were classified according to season, distance away from the bee-hive, family, genera, species. Simpson and Shannon diversity indices were found higher (0.004 and 3.45) for summer16. Asteraceae family was found to be the most preferred species. Distance of each bee flora was not found significant but season and herbaceous flower were found highly significant contribution. Maximum abundance of Solanum virginianum L. appeared towards the positive end of non-metric multidimensional scaling axis (NMDS2) which was closer to summer16. It signified closer affinity to the beehive and high preferences during summer15. Likewise, the maximum abundance of Vitis vinifera L. towards summer16 and higher positive end of NMDS1 signified favoring more wet loving early blooming species. Relatively higher abundance of species such as Parthenium hysterophorus L., Solanum tuberosum L., Zinnia elegans Jacq., and Solanum melongena L. in the middle of the NMDS axis and spring 16 signified moderate moist loving species. Pattern of bee flora selection, contribution in term of nectar and pollen grain coincided to moisture gradient. This study supports bee farmers for better selection of wild as well as cultivated bee flora for better preference by bees.","PeriodicalId":19905,"journal":{"name":"Our Nature","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83766579","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}

Therefore, this study aims to explore avian diversity, its pattern, and environmental variables affecting bird species richness along elevation gradients. The point count method was carried out in the monsoon season (June and July) in 2019. Data for environmental variables including elevation, distance to settlement, distance to nearest water sources, temperature, and precipitation were assessed with respect to the feeding guild. A total of 130 species of bird belonging to 40 families and 12 orders were recorded including the Steppe eagle (endangered species) and Spiny Babbler (only endemic bird of Nepal), which indicate that SNNP supports avian diversity. Diversity indices showed diverse bird community assemblage such as the Shannon-Weiner diversity index (H'=2.65), Simpson diversity index (0.92), and evenness index E=0.94). Our study revealed insectivores were dominating among others and the order Passeriformes had the high species richness. Our observation revealed that the bird species richness was significantly greater at lower elevations than at mid and high elevations, showing a clear monotonic decline in species richness and diversity with increasing elevation. In the case of feeding guild (insectivores, omnivores, frugivores, and carnivores), most of the bird species showed a significant relationship with environmental variables (elevation, distance to settlement, distance to nearest water sources, temperature, and precipitation). It was concluded that not only environmental factors are responsible for affecting avian diversity but elevational gradients consisting of heterogeneous habitats can also play an important role in shaping avian diversity patterns.","PeriodicalId":19905,"journal":{"name":"Our Nature","volume":"107 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91298042","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}
