Alpine steppe is considered to be the largest grassland type on the Tibetan Plateau. This grassland contributes to the global carbon cycle and is sensitive to climate changes. The allocation of biomass in an ecosystem affects plant growth and the overall functioning of the ecosystem. However, the mechanism by which plant biomass is allocated on the alpine steppe remains unclear. In this study, ...

Microbial abundance and diversity in deep subsurface environments is dependent upon the availability of energy and carbon. However, supplies of oxidants and reductants capable of sustaining life within mafic and ultramafic continental aquifers undergoing low-temperature water-rock reaction are relatively unknown. We conducted an extensive analysis of the geochemistry and microbial communities r...

Age delimitation integrated with aeromagnetometric and aerogammaspectrometric survey advances the understanding of ophiolite evolution in Brasiliano Orogen. We focused on Bossoroca ophiolite, because oceanic crustal mantle rocks contain zircon metasomatic chloritite. A metadiorite a metavolcanoclastic rock were also studied to delimit relationship between island-arc infrastructure superstructur...

Understanding the vulnerability of forests and its associated factors is crucial for sustainable management forested landscapes. The assessment in Indian Western Himalayan (IWH) region comprising states Jammu & Kashmir (J&K), Himachal Pradesh (HP) Uttarakhand (UK) was done using six indicators form biological richness index, disturbance forest canopy density, fire point intensity extraction fri...

Persistent Organic Pollutants (POPs) and Polycyclic Aromatic Hydrocarbons (PAHs) are important classes of compounds of serious environmental concern. These compounds were measured in waters, sediments and soils from several high altitude sites in the Sagarmatha National Park (Nepal) and included in the Himalayan ridge. In water samples, low-level substituted PCBs and PBDEs, along with more vola...
