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...

Among developing countries, Nepal has been an enthusiastic leader in experimenting with participatory systems of forest governance. This article evaluates the state-initiated implementation of the leasehold forestry programme in Nepal, aimed at providing better livelihoods to the poorest sections of society by leasing patches of degraded forest land for a 40-year period. Using case studies in the...
The Nanda Devi Biosphere Reserve (NDBR) in the western Himalayas is one of the important protected areas in India. In recognition of its conservation value, it was designated as a World Heritage Site by UNESCO in 1988. The Nanda Devi west peak (7817 m), the second highest in the country, attracted a large number of mountaineers and nature enthusiasts from all over the world until 1982. However,...
Mountain systems in India, including the Himalayan region are characterised by highly complex socio-ecological systems, with rich cultural diversity linked with equally rich biological diversity. With a large number of ethnic societies having their own social, economic and cultural attributes placed in a highly heterogenous mountain environment, any conservation-linked developmental initiative...
Matsutake (Tricholoma spp.) are a group of commercially important mushrooms that are increasingly threatened by over-collection. Ecologically sustainable management of matsutake has been hindered by the lack of essential information such as reliable distribution maps. Although a variety of spatial distribution models have been applied to map many different plants, this has rarely been attempted...

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...
