Data compared to 2008, showed decline in the total number of birds. The results showed that while some bird benefitted from replenished fish stock, many others suffered. South Asian River Dolphin <em>Platanista gangetica </em>increased in number within the Koshi Tappu Wildlife Reserve after the flooding. Poverty and illiteracy contributing to lack of awareness amongst local people were hampering conservation works in the Reserve.</p><p>DOI: <a href="http://dx.doi.org/10.3126/njbs.v2i0.7482">http://dx.doi.org/10.3126/njbs.v2i0.7482</a></p> <p><em>Nepalese Journal of Biosciences </em>2 : 1-4 (2012)</p> 2013-01-24T00:00:00+00:00 Copyright (c) https://nepjol.info/index.php/NJBS/article/view/7483 Toxic effects of herbicides on transplanted paddy 2013-01-24T08:30:44+00:00 Chandra Bahadur Thapa cbthapa@yahoo.com <p>The effectiveness of two herbicides <em>viz</em>., 2 4-D and butachlor for the control of weeds in transplanted paddy and improving the grain yield was studied. Slight toxic effect of herbicides on paddy plants was noticed at 21 days after transplanting of paddy seedlings. However, it didn’t persist for long and had no overall harmful effect on grain yield. Both the herbicides produced satisfactory control of the weed population and dry matter. This resulted in a significant increase in grain yield over un-weeded control.</p> <p>DOI: <a href="http://dx.doi.org/10.3126/njbs.v2i0.7483">http://dx.doi.org/10.3126/njbs.v2i0.7483</a></p> <p><em>Nepalese Journal of Biosciences </em>2 : 5-9 (2012) <strong> </strong></p> 2013-01-24T00:00:00+00:00 Copyright (c) https://nepjol.info/index.php/NJBS/article/view/7484 Effect of disturbance on fine root biomass in the Tropical moist forest of eastern Nepal 2013-01-24T08:30:44+00:00 Tilak Prasad Gautam tilakg673@gmail.com Tej Narayan Mandal tilakg673@gmail.com <p>Fine root biomass (&lt;5 mm diameter) was estimated in 0-15 cm and 15- 30 cm soil depths of disturbed and undisturbed stands of tropical moist forest in eastern Nepal.

Based on the recovery in ecosystem properties; the 58- year-old landslide damaged site demonstrated the re-establishment of an ecosystem showing closer affinity with the mature sal forest. On the basis of best fit power function models it was concluded that the estimated times for the 58-year old site to reach the level of undisturbed matured sal forest would be about 30-35 years for microbial biomass (C and N) and plant biomass and about 100-150 year for soil organic Carbon and total N. Higher accumulation of soil microbial biomass, plant biomass and high N-mineralization rate at late successional stages indicated the re-establishment of an ecosystem with enriched soil and restitution of nutrient cycling during the course of ecosystem restoration</p> <p>DOI: <a href="http://dx.doi.org/10.3126/njbs.v2i0.7488">http://dx.doi.org/10.3126/njbs.v2i0.7488</a></p> <p><em>Nepalese Journal of Biosciences </em>2 : 40-45 (2012)</p> 2013-01-24T00:00:00+00:00 Copyright (c) https://nepjol.info/index.php/NJBS/article/view/7489 Physico-chemical properties of Seepage stream at Shripur area, eastern Nepal 2013-01-24T08:30:44+00:00 Damodar Thapa Chhetry thp_damodar@rediffmail.com Joydeb Pal thp_damodar@rediffmail.com <p>Physico-chemical parameters of the Seepage stream of Shripur area were studied for two years from July, 2002 to June, 2004, once in every month at regular intervals.

Nepalese fishes are one of main aquatic vertebrates which are yet to be studied for their occurrence, distribution and ecology, especially from western regions of the country. However, before complete understanding on native fishes, threat over their existence have been loomed by climate change, over fishing, pollution, alteration of natural habitats and poor understanding of fish ecology etc. Thus, publicizing the importance and knowledge of fish conservation has been one of the most important challenges. The other challenges are sustainability of quality and quantity of freshwaters which have been impacted. In such circumstance to overcome the problems, adoption of community or cooperative based conservation could be one of the best approaches for freshwaters and fish restoration. Optimistically, a national strategy on conservation of freshwater fish is desirable. Fish conservation has the opportunities to be used for multidimensional purposes. A success of single fish species might contribute substantially on local economy, if that could be used in aquaculture or angling for tourism industry.</p> <p>DOI: <a href="http://dx.doi.org/10.3126/njbs.v2i0.7492">http://dx.doi.org/10.3126/njbs.v2i0.7492</a></p> <p><em>Nepalese Journal of Biosciences </em>2 : 71-79 (2012)</p> 2013-01-24T00:00:00+00:00 Copyright (c) https://nepjol.info/index.php/NJBS/article/view/7493 Soil microbial biomass in relation to fine root in Kiteni hill Sal forest of Ilam, eastern Nepal 2013-01-24T08:30:44+00:00 Krishna Prasad Bhattarai krishnaprbhattarai@gmail.com Tej Narayan Mandal krishnaprbhattarai@gmail.com <p>Soil microbial biomass in relation to fine root was studied in Kiteni hill Sal (<em>Shorea robusta</em>) forest of Ilam during summer season.

Regarding other information about the impact of climate change in the context of Nepal, literature survey was done. Edible molluscs are cheap non-conventional source of protein for huge population of poor ethnic peoples (53 castes living in twenty districts of Tarai in Nepal), from time immemorial. Up to, nearly four and half decades back, there were virgin forests in Tarai region, water sources were in better condition but because of rapid population explosion, encroachment of wetlands and deforestation the water sources began to dry up early in the year. Gradual increase in atmospheric temperature due to imbalanced amount of CO<sub>2</sub> and precipitation, is worsening the environment. The climate change is not only destroying the suitable aquatic environment of the molluscs habitats but their foods of plant and animal origins as well. Several changes in water chemistry might have taken place threatening aquatic lives including molluscs. As a result, annual production of mollusc also has decreased. The climate change is enforcing molluscs to change their original habitats and habits. While their production of molluscs is decreasing, demand is increasing due to rapid human population growth. The price of molluscs meat also has increased 100% as compared to one decade back (<em>Bellamya </em>Rs 20-25/kg with shell, <em>Pila </em>without shell Rs 48-60/kg, similarly bivalves (<em>Lamellidens </em>and <em>Parreysia) </em>Rs 20-30/kg with shell whereas Rs 50-60/kg without shell; <em>Brotia </em>Rs 10-12/kg with shell). Local production of Nepal covers hardly 30-40% demand of molluscs. The rest 60% demand is met imported from India. The only solution of the problem is to initiate molluscs culture which will also help conserve water sources and other aquatic organisms as well.</p> <p>DOI: <a href="http://dx.doi.org/10.3126/njbs.v2i0.7496">http://dx.doi.org/10.3126/njbs.v2i0.7496</a></p> <p><em>Nepalese Journal of Biosciences </em>2 : 98-108 (2012)</p> 2013-01-24T00:00:00+00:00 Copyright (c) https://nepjol.info/index.php/NJBS/article/view/7497 Seed attributes, germination responses and seedling growth of silk cotton tree Bombax ceiba L. 2013-01-24T08:30:44+00:00 Bhabindra Niroula niroulab@gmail.com Dillli Ram Pokhrel niroulab@gmail.com Sasinath Jha niroulab@gmail.com <p><em>In vitro </em>Seed germination through different treatments, and seedling growth of <em>Bombax ceiba </em>were studied from April 2009 to January 2010.

Ethno-medicinal uses of turtle by <em>Satar</em>, an indigenous ethnic community of southern Jhapa for human and domestic animals have been documented. Most of the diseases are treated by the use of turtle shell of <em>Lissemys punctata.</em></p> <p>DOI: <a href="http://dx.doi.org/10.3126/njbs.v2i0.7500">http://dx.doi.org/10.3126/njbs.v2i0.7500</a></p> <p><em>Nepalese Journal of Biosciences </em>2 : 126-133 (2012)</p> 2013-01-24T00:00:00+00:00 Copyright (c) https://nepjol.info/index.php/NJBS/article/view/7501 Survey of marketable vegetables and edible fruits in Dharan, eastern Nepal 2013-01-24T08:30:44+00:00 Sabitri Shrestha sabli123123@yahoo.co.in Shiva Kumar Rai sabli123123@yahoo.co.in <p>A total 77 types of vegetables and 33 fruits were recorded from the markets of Dharan during the period of one year.
