A comparison of attachment, engorgement and moulting success of Amblyomma hebraeum larvae fed on domestic chickens and Himalayan giant white rabbits indicates that chickens are better hosts than the rabbits. Moreover the time needed for detachment of all engorged larvae is significantly less for chickens than for the rabbits. No evidence of induced immunity was found in chickens on re-infestati...

We assess biodiversity status of Rotifera known from India to-date based on our studies various regions this country and evaluation other viable records, highlight notable features biogeography richness. The Indian fauna reveals 434 valid species belonging to 68 genera 25 families thus indicates the most biodiverse vis-àvis south Southeast Asia, records ~25% ~41% global regional biogeographic i...

With the help of ERS 1 and 2 tandem data, we have produced DEM and glacier movement of two major Himalayan glaciers in India. The glaciers showed good correlation but the surrounding areas had more decorrelation. Contours generated with ERS 1 and 2 SAR tandem data are comparable with topographic maps. We have used SRTM DEM to study the glacier movement involving two-pass differential method. Th...

We describe volumetric changes in three benchmark glaciers in the Nepal Himalayas on which observations have been made since the 1970s. Compared with the global mean of glacier mass balance, the Himalayan glaciers showed rapid wastage in the 1970s-1990s, but similar wastage in the last decade. In the last decade, a glacier in an arid climate showed negative but suppressed mass balance compared ...
