Here, we report on an investigation of the seasonal distribution of potential artificial breeding habitats of A. albopictus in urban areas of the Kathmandu and Lalitpur districts of Nepal. Larval collections were performed from April 2009 to March 2010 simultaneously in all the wet containers present in and around the houses of the study areas. Altogether 1873 water containers in Kathmandu district and 1807 in Lalitpur district were searched in 12 months, out of which 107 (5.7%) and 129 (7.1%), respectively, were found positive for A. albopictus breeding. Within the urban agglomeration of both districts, the breeding was found to vary between localities. Immature stages of A. albopictus were recorded in pre-monsoon, monsoon and post-monsoon seasons as 1.9%, 6.7% and 5.6%, respectively, in wet containers in Kathmandu district. In Lalitpur district, A. albopictus larvae were detected in 4.6%, 7.6% and 7.1% of the wet containers in the pre-monsoon, monsoon and post-monsoon, respectively. The breeding preference ratio during all seasons was highest for discarded tires lying outdoors in both Kathmandu and Lalitpur districts. Among nine container types searched and examined, 95% of discarded tires were found positive for A. albopictus larvae and pupae, followed by metal drums (2%) and plastic drums (1.25%). Continued and increased urbanization and vehicle movement in Kathmandu and Lalitpur districts have resulted in increased amounts of non-biodegradable containers such as tires around human dwellings, thereby creating ideal breeding habitats for A. albopictus.","PeriodicalId":89691,"journal":{"name":"Journal of natural history museum","volume":"26 1","pages":"181-193"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3126/JNHM.V26I0.14142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69290385","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}

Only one breeding male was observed reflecting the critical condition for the breeding in the wild within Chitwan National Park. The abundance of the gharial was restricted in 2 areas, namely Khoria muhan and Velaunji due to suitability of the habitat conditions and minimum human disturbances. The Basking activities in relation to depth showed that > 80 % of the Gharials selected sandy banks. Among the 2 populations, the gharials in Khoria muhan preferred shallow to moderate depth of water because of presence of braided channels in the area. In contrast, the Gharials in Velaunji select deep water course of the main channel. The park management must adopt conservation measures such as ban of fishing and regular monitoring of habitats and population to maintain long term conservation of gharials in Narayani river. J. Nat.

The sample was harvested fresh, sundried, pulverized and analyzed according to standard procedures. Screening revealed the presence of volatile oil, alkaloid, carotenoid, steroid, triterpenoids, fatty acid, emodins, flavonoid, coumarin, anthracene glycoside, anthocyanadine glycoside, tannins, saponins, glycosides, polyurenoid and polyoses in the ethereal, methanolic and aqueous extracts. There were significant differences in the phytochemical composition of the samples collected from east, center and west eco-zones and tropical, subtropical and temperate climatic regions. There was definite co-relation between the traditional application of Termite’s mushrooms and possession of secondary metabolites, which supports the scientific basis for the traditional medicinal system.

In this investigation, a wide range of foraging plant sources for Apis cerana honey bees was identified which demonstrates the adequate potential for expanding and sustaining beekeeping in this area. The palynological assemblage of a total of 44 species of pollen flora representing 28 families was identified to the generic and some up to species level. Some of the pollen grains identified to only families, belong to Acanthaceae, Apiaceae, Araliaceae, Chenopodiaceae, Compositae, Lamiaceae, Loranthaceae, Meliaceae, Poaceae, Rosaceae, Rutaceae and Pteridaceae. The pollen assemblages in honeys were mostly belonging to angiosperms while the gymnosperm pollen was completely absent. One pteridophyte spore belonging to family Pteridaceae recovered.

In the present study, propagation of Ginkgo biloba L. was conducted using hardwood and semi hard wood cuttings. The cuttings from basal part of the tree were selected for the experiment and planted during rainy (i.e. July) and summer season (i.e. April) at Central Department of Botany, T.U. Cuttings beds were prepared using 3:1 sand and soil. Different concentration of auxins such as IAA, NAA and IBA were found effective in inducing rooting. During July, the stem cuttings treated with 1000 ppm IAA for 30 minutes induced highest percentage (90 %) and statistically signifi cant (P< 0.05) rooting while those treated with same concentration and time induced only 40% rooting during April. Like wise other auxins NAA and IBA induced more rooting during July and less rooting during April. Cuttings planted as control, during July showed 10 % rooting while during April did not show any rooting. Among all the auxins studied, IAA hormone and rainy season was found to be the most effective for rooting of G. biloba cuttings. From the anatomical study it was revealed that vascular cambium, secondary phloem, cortical cells and pericycle cells took part on rooting. Successfully rooted cuttings were then transferred to the natural soil condition. J. Nat. Hist. Mus.

The forest plots were categorized into disturbed and semi-disturbed considering the scale of anthropogenic disturbances such as percentage of biomass extraction, lopping, tramping coverage and grazing intensity. For each forest type, three radii (10 m, 5 m and 2.5 m) plots were laid for sampling trees, sapling and seedling layers, respectively. In both the forest sites, Quercus semecarpifolia and Rhododendron arboreum were the main dominant tree species. The distribution of Q. semecarpifolia and R. arboreum along with diameter classes showed high stem density mainly concentrated in 2-15 cm diameter class. In both sites, the density of R. arboreum showed increment from sapling to seedling stage, while no seedling of Q. semecarpifolia was recorded in the disturbed site. The absence of Q . semecarpifolia seedlings in the disturbed forest sites could be associated with the practice of biomass removal and forest management activities. The study attributed that Rhododendron species in the study sites were not frequently cut, browsed, or lopped due to their religious belief and its ornamental value. Thus R. arboreum is expected to be slowly expanded if biotic pressure is maintained less. This may cause change in the vegetation structure and scarcity of resources for livelihood. On the whole, managing the forest in an equitable and sustainable way could satisfy basic needs and improve the livelihood of rural people in the study area. J. Nat. Hist. Mus.
