Why PhD theses...

PhD thesis is the result of years of hard work.

keyword researchMeasured by download count PhD theses are one of the most popular items world wide on open access repositories. But unless a thesis is published, it is very difficult for other researchers to find out about it and get access to it. Theses are often under-used by other researchers. Thesica.org attempts to address this issue by making it easy to identify and locate copies of many theses in various disciplines.

ABSTRACT

The main objective of this thesis is to develop and refine widely applicable techniques for gathering data on ecological relationships among the three predators (tiger, leopard and dhole) and their prey species. The study area, the Nagarahole National Park is known to have one of the highest densities of large mammals in Asia.

In this project, base-line data was collected on carnivore-herbivore populations using latest techniques. The densities and group size of large herbivores by habitat and season, the age and sex composition, reproduction among populations of large herbivore species, densities, food habits and reproductive status of three large predators and the impact of predation on large herbivore populations were assessed in the course of this project.
