Introduction
I am a botanist broadly interested in the disciplines of taxonomy, ecology, biodiversity, climate change and soil. I am currently working as a senior researcher at Centre for Biodiversity and Taxonomy, Department of Botany, University of Kashmir, Srinagar. To assess alpine vegetation patterns along elevation and its response to climate change in Himalaya is not only my heart-centred goal but an endless passion.

Globally, treeline in mountain landscapes is reported to be sensitive to projected warming by climate change. Betula utilis (Himalayan birch), a principal tree species defining the natural treeline in Himalayas, is a potential indicator species to track the signal of climate change. The present study models the ensemble distribution of B. utilis us...
Under the contemporary climate change, the Himalaya is reported to be warming at a much higher rate than the global average. However, little is known about the alpine vegetation responses to recent climate change in the rapidly warming Himalaya. Here we studied vegetation dynamics on alpine summits in Kashmir Himalaya in relation to in situ measure...
Although vegetation has been the focus of recent studies on mountain summits , little is known about smaller-scale spatial patterns of soil physico-chemical properties. Here, we report patterns and drivers of soil physico-chemical properties and their role in shaping the plant diversity on mountain summits of the Himalaya. Using the globally standa...
In an era of global environmental change, the treeline shift triggered by recent climate warming has been reported worldwide. However, it is still unknown how site-specific microclimatic conditions regulate the soil-vegetation relationship at treelines, which constrains our capacity to down-scale broad global trends in the treeline shift at regiona...
Globally, treelines form a transition zone between tree‐dominated forest downslope and treeless alpine vegetation upslope. Treelines represent the highest boundary of “tree” life form in high‐elevation mountains and at high latitudes. Recently, treelines have been shifting upslope in response to climate warming, so it has become important to unders...
Patchy global data on belowground litter decomposition dynamics limit our capacity to discern the drivers of carbon preservation and storage across inland and coastal wetlands. We performed a global, multiyear study in over 180 wetlands across 28 countries and 8 macroclimates using standardized litter as measures of “recalcitrant” (rooibos tea) and...

Treeline ecotones, the transition zone between the upper closed forest limit (timberline) and treeless alpine vegetation, are the most conspicuous features of mountain ecosystems around the world. Understanding the patterns of plant species richness in the treeline ecotones is crucial in accurately assessing and monitoring the treeline shifts and v...
Canopy height is a key physiognomic parameter of biodiversity, productivity and other ecosystem functions in high-elevation alpine ecosystems. However, little is known as to how altitude influences canopy height in these ecosystems. This study makes use of an open-access global forest canopy height map with a spatial resolution of 30 m that integra...
Globally, the treelines at higher elevations in mountains are reported to be advancing up-slope in response to recent climate warming. However, little is known about the treeline advancement in the Himalaya due to paucity of baseline vegetation data with which to compare, thus making their assessment and monitoring challenging. To fill this knowled...
Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we...
Environmental and toxicological problems have significantly increased from the last couple of decades due to non-judicial agrochemicals. There is a drastic decrease in the growth and yield of most crops due to diseases and infections, and globally the insects and pests reduce the overall crop production by nearly 20%.
