European foulbrood disease is a broad disease in honey bees caused by a bacterium, Melissococcus plutonius. By now, various herbal and chemical drugs have been tried to control it. In the present study, the effects of different organic extracts of three different bryophytes and a standard drug (positive control) have been tried to control the bacterium in vitro by using agar disc diffusion and micro broth dilution method.

This article reports the greenhouse gas emissions of anthropogenic origin by sources and removals by sinks of India for 2007 prepared under the aegis of the Indian Network for Climate Change Assessment (INCCA) (note 1). The emission profile includes carbon dioxide (CO2), methane and nitrous oxide. 

The article reports projection of malaria by 2030 using A1B scenario of PRECIS model basically derived from HadRM3. Malaria scenario has been defined in terms of opening of months of malaria transmission based on minimum required temperature and relative humidity for baseline (1961–1990) and by 2030. Detailed analysis has been done for four vulnerable sectors, viz. Himalayan region, northeast, the Western Ghats and coastal region. 

An assessment of the impact of projected climate change on forest ecosystems in India based on climate projections of the Regional Climate Model of the Hadley Centre (HadRM3) and the global dynamic vegetation model IBIS for A1B scenario is conducted for short-term (2021–2050) and long-term (2071–2100) periods. Based on the dynamic global vegetation modelling, vulnerable forested regions of India have been identified to assist in planning adaptation interventions.
