Abstract :To know rodent species in an area is important in wildlife management studies, forestry applications, conservation purposes, and public health studies because of some rodent-borne diseases. To determine rodent species and their distribution in Zonguldak was aimed to supply a detailed inventory data and distribution maps for further studies in future. Samples were collected mostly by Sherman traps, and rarely conventional cage-like traps, phototraps, or visually from 33 localities that represent different habitat types, between 2009 and 2016. A total of 427 specimens from 15 species were evaluated. These species are: Sciurus anomalus, Myodes glareolus, Microtus subterraneus, M. levis, Apodemus flavicollis, A. sylvaticus, A. uralensis, A. witherbyi, A. mystacinus, Rattus rattus, R. norvegicus, Mus domesticus, M. macedonicus, Glis glis and Muscardinus avellanarius. Of them S. anomalus, M. levis, A. uralensis, M. macedonicus and M. avellanarius were recorded by primary data for the first time from Zonguldak. According to the results, Sciurus anomalus, Apodemus flavicollis and Glis glis are the most common species by being recorded from 13, 12 and 9 localities, respectively. Among the 33 localities trapped, Kurtköy and Beldibi areas have highest number of rodent species by each having 7 species. Trap Night Index insert ignore into journalissuearticles values(TNI); was calculated to find the most caught rodent species, the overall trap success for rodents caught and the localities where the majority of rodent samples were caught. TNI was calculated as 21.43 for seven of the localities studied. Skull and pelage morphology insert ignore into journalissuearticles values(pectoral spot expressions, the posterior end of the palatal bone, pterygoid process, fronto-parietal suture and upper molar crown patterns); were used to identify Apodemus species. Morphological evaluations of Apodemus specimens verified the occurrence of A. sylvaticus in Asiatic Turkey.
