    Plant diversity gradients along the Himalaya: A comparison between the east and the west
    (Wildlife Institute of India, Dehradun, 2018) Kumar, Suresh; Rawat, G.S.; Price, Trevor
    Patterns and causes of latitudinal and elevational diversity gradients have gained increasing attention in the field of macroecology. A monotonic decline in species richness from low to high latitudes and elevations was widely accepted as the common pattern for a long time. However, reviews of the available literature on patterns of species diversity along elevational radients show that species richness often does not monotonically decline with elevation. In this thesis, I analyse the elevational and latitudinal patterns of plant species richness across the Himalaya.

    Ecology and management of savanna vegetation in Sariska Tiger Reserve, Rajasthan.
    (Wildlife Institute of India, Dehradun, 2015) Bhatt, Priyanka; Rawat, G.S.; Sankar, K.
    This study is aimed to document the role of various abiotic and biotic factors playing a vital role in the coexistence of trees and grasses. Attempts have been made to bridge the research gaps related to the structure and composition of forest vegetation, phenology diversity and regeneration patterns along the landscape. Hence, present study was initiated with a view to collect baseline data that would be helpful in monitoring the forest changes in future. It provides information about the savanna vegetation and the dynamics and also deals with the vegetation composition, species diversity, richness and other phyto- sociological parameters, Vegeation structure, composition and factors affecting the savanna vegetation in Sariska Tiger Reserve. Objectives are : 1. To study the phenology of savanna species 2. To study the aut-ecology of dominant savanna grasses and tree species of Sariska with reference to biotic and abiotic factors 3. To study the impact of invasive species and management implications: case study of Adhatoda vasica
