The interaction and interviews with local peoples was organised to collect initial confirmation on occurrence of the red panda. For sign survey of animal, altogether 20 quadrate plots (each of 10×10 sq. meters) at the point where pellets of red panda were found, were laid between altitude of 2800 m to 3300 masl. The presence of Red panda pellets in the study area was major evidence of presence of redpanda in the area. The lowest altitude in which pellet found was 2993 m and the highest was3297 m. The highest number of pellets was observed in altitudinal range of 3100 m to 3150m. The average number of pellets per group was 10.13 ± 5.33. The typical dominant species of trees in red panda habitat were Betula utilis, Abies spectabilis and Quercus semecarpifolia observed with the highest Important Value Index (IVI) of 83.80, 75.83 and 52.80 respectively. Nigalo (Thamnocalamus sp.), the most preferable food plant of red panda, was distributed widely in the study range.

Wetlands in Nepal support a total of 27% of nationally threatened birds. Barandabhar forest is only one vertical (south-north) bio-corridor that links two different ecosystems, CNP and the Mahabharat hill range. Eight wetlands were selected for water birds monitoring by using area search and point count methods to explore the diversity and conservation threats of water birds in Barandabhar corridor forest. This study recorded 3664 individuals of water birds belonging to 54 species, 11 orders and 13 families in which the highest numbers of the species were belonged to order Passeriformes (17 species). The diversity of water birds in eight different wetlands showed the highest diversity in Rapti river (H= 3.403), followed by Beeshazari lakesystem (H= 3.401), Batulpokari lake area (H= 3.377) and the rest of others. The least diversityof water birds was found in Gundremandre lake (H=2.210). Similarly, the species dominance was more in Gundremandre lake (D=0.189) than Beeshazari (D=0.046) and Batulpokhari (D=0.042). The species richness in various habitats association with wetlands showed that Shorea forest association was utilized very less as compared to its availability. Fishermen (r= -0.391, t = 10.6, P<0.0001) and livestock pressure (r = -0.276, t = 6.63, P = 0.0009) caused the significant negative impact on the occurrence of water birds in many parts of the study sites. The study suggests that annual flooding in the rivers (e.g., Rapti, Budhirapti and Khageririvers), human disturbance (e.g., livestock grazing and fishing), habitat loss and degradation, declining water quality and quantity caused by eutrophication and chemical pollution are the major threats of water bird communities in Barandabhar corridor forest.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3126/jnhm.v30i0.27553","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69291915","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}

Study revealed that majority of respondents noticed change in wetland in past years and in their priority, drying ranked first followed by decrease in acreage, and biodiversity loss. It was found that factors responsible for these changes were drought, encroachment, flooding, erosion and succession by invasive weed species. Study found that local peoples have several impacts on wetland which were conversion for agriculture, discharge of pollutants, overexploitation of aquatic resources, overgrazing conversion for residential development, and conversion for aquaculture. However, Negative impacts of wetland were flooding, foul smell, incidence of insect pest/disease, coldness in winter, and bank cutting. It was found that people dependent on wetland for farming, fodder collection, fuel wood collection, medicinal plants, religious purpose, fishery, livestock grazing, wild edible plants, irrigation, commercial fishery and recreation. Study showed that local peoples have knowledge about several aspects of wetland and they are dependent for their livelihood. Therefore, in order to protect wetland from degradation, conservation and management activities need to be implemented properly with the involvement of local peoples.","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":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49157636","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 the lack of knowledge on floral biology and fruiting of this plant remains a problem to increase its yield and improve farmers’ adoption. The objectives of this study were to assess seasonal changes on flowering and fruiting of six accessions of Jatropha curcas in semi-arid area, Senegal. In this study the total number of inflorescences, flowers and fruits were evaluated during six month son four years old plants, installed in the Agricultural Engineering School ( ENSA) of Thies. The results showed significant effect of the studied factors (season, accession) and interaction between them on floral and fruiting traits of J. curcas. Due to more favorable climatic conditions, the performance of flowering is better in the wet season. During this season, the number of male and female flowers ranged, respectively from 107.47–191.60 and from 2.47–11.87 per inflorescence. Consequently, ripe fruits production was higher in wet season and varied between66 and 97% of the total production. Two peaks of flowering were observed; the first one occurred in dry season (April, 24th- June 6th) and the second, with the highest number of inflorescences, arrived in wet season (8 - 22 July). Fruiting patterns is highest concentration between at the end of the wet season (September 15th and October 3rd).High seed yields were observed with the accessions CE6 (2739.3 kg ha-1), CE97 (1451.0 kg ha-1) and CE95 (1326.3 kg ha-1) that are promising for biofuel production in semi-arid areas of Senegal.","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":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47377808","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 aim of this study was to test the impact of forest floor fire on soil carbon sequestration. We measured total carbon stock in soil of unfired and fired sites of different intensities namely: high frequency and high intensity, high frequency and moderate intensity and high frequency and low intensity. There was significant difference (P=0.00) of the soil organic carbon between the sites and different soil depths tested by one-way ANOVA. Similarly, one-way ANOVA test showed that soil charcoal stock was significantly different (P=0.00) at different soil depths. The value of CO2 flux was increased with increasing volumetric water content and decreasing soil temperature. One-way ANOVA showed significant difference (P=0.00) of volumetric water content, soil temperature and CO2 flux between the sites. In high frequency and medium intensity site, high amount of carbon sequestrated in soil suggested that fire of medium intensity mitigates high CO2 from the atmosphere.","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":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48646609","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}
