Understanding aspects of demography and resource partitioning mechanisms of large felids among with abundance and spatial distribution of prey in Similipal Tiger Reserve, Odisha

Abstract

This study investigates the crucial aspect of coexistence for large predators like tigers and leopards sharing the same landscape and delves into the population dynamics of these animals by identifying the mechanisms of resource partitioning. By acting as a window into the inner workings of the ecosystem, the study reveals how tiger and leopard populations function alongside each other. Identifying the factors that influence their ability to share the resources successfully is vital for developing more effective conservation strategies. This knowledge ultimately contributes to ensuring the long-term survival of both tigers and leopards in this landscape. A precise assessment of several demographic parameters is necessary to make informed management decisions for their conservation within this unique habitat. These parameters include population density, sex structure, recruitment, and survival rates. With this background, the study comes with the following objectives. (1) To assess the abundance and spatial distribution of prey in STR.(2) To assess the various demographic parameters of large felids (tiger and leopard) in STR. (3) To determine the mechanisms of resource partitioning of the tiger and the leopard in STR. Similipal Tiger Reserve is located in the Mayurbhanj district of Odisha, between86˚06' and 86˚36' East longitude and 21˚31' and 22˚02' North latitude. The study was carried out over three years (2019–2021) across eight ranges in the core area of STR: Chahala, Nawana North, Nawana South, and Pithabata South Wildlife in the northern core, and UBK, Jenabil, Bhanjabasa, and National Park in the southern core.
