This paper deals with the diatoms from Upper Mustang Trans-Himalaya Region, Nepal.
A total of forty mature specimens of Noemacheilus montanus collected from river Alaknanda and its tributaries ranging from 7.0 cm to 9.2 cm in length and from 2.31 g to 5.49 g in weight were used for the present study. The fecundity was calculated to be 500 to 1005. The relationships between fecundity and total length, total weight, ovary length and ovary weight were found to be...
Two hundred and seventeen species of birds belonging to 48 families were recorded in the three year study at the Gudavi sanctuary, Sorab, Shimoga district, Karnataka. Most of the families were represented by less than thirteen species except for Muscicapidae (35 species). These include 160 residents, 46 resident migratory and 11 migratory birds. 54 species of water dependent birds were...
The viability of biodiversity conservation based uniquely upon a model of protected areas is being questioned in the developing world, and new evidence is emerging on the social and ecological costs of displacing people in order to impose wilderness. This re-evaluation of the strict protected area model is driven in part by new data showing that some human-dominated regimes of land use...
This paper reports the main findings of a study on the factors threatening biodiversity in northwest Yunnan, a global biodiversity 'hotspot' in China and home to over five million people. The research was based on eight site-level case studies. The main driving forces of biodiversity loss are livelihood activities, including agricultural production, livestock grazing and the collection of fuel...
Invasive alien species colonise aggressively, threatening native biodiversity. The success of invasive alien plants is due to their opportunistic exploitation of anthropogenic disturbances, the absence of natural enemies, and, frequently, their allelopathic competitive strategies. Invasive species can have a significant impact on development, affecting sustainability of livelihood, food...
