| Abstract | The estimated population of the Tsushima leopard cat Prionailurus bengalensis euptilura is only 80–110 individuals. However, the cause of the population decline is not clear. We investigated temporal changes in the food habits of the cat and two other species of Carnivora (marten and weasel) inhabiting the Tsushima Islands by measuring δ$^{13}$C and δ$^{15}$N values in hair samples. Hair samples of the cat were collected not only from specimens and furs, but also from feces. The gathering of hair from cat feces was most efficient when the feces were collected in the spring. The food habit of male cats seemed to be more diverse and tended to comprise prey of higher trophic levels than the food habits of the females. The δ$^{13}$C and δ$^{15}$N measurements suggested that the trophic level of the food sources has been decreasing over the last several decades for the cat and weasel, but not for the marten. Increased consumption of prey from lower trophic levels in the food habit of the cat seems to be related to the decline of the cat population because these phenomena occurred simultaneously. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
