Abstract
Camera trapping is one of the most effective methods for mammal inventories in most habitats and conditions. This study is based on the mammal records of a camera trap study in Northwest Anatolia. The study area was about 3500 km2 , and the study was carried out between May 2014 and May 2015. A total of 62 sites were surveyed, resulting in 3653 records of 16 mammal species Sciurus anomalus, Erinaceus concolor, Felis silvestris, Canis lupus, Canis aureus, Vulpes vulpes, Ursus arctos, Meles meles, Martes foina, Martes martes, Mustela nivalis, Lutra lutra, Sus scrofa, Capreolus capreolus, Lepus europaeus, Cervus elaphus in 11,868 camera trapping days. The highest detection rate among the species was that of Sus scrofa 36.57% , followed by Martes spp. 20.35% and Canis aureus 19.44% . Overall trap success for all species detected was 30.78% recorded number/100 camera trapping days . It was detected that mammal species diversity was higher in natural forested lands than in human-affected areas. Species diversity in the study area was recorded to be significantly higher than the results of other studies from different parts of Turkey. We present here a detailed inventory, distribution data, and contemporary diversity data for the study area, and comparative data for further studies.
Highlights
The Mediterranean region hosts 321 mammal species (Temple and Cuttelod, 2009), 154 of which are found in Turkey, including about 20 large and medium-sized mammals (Kumerloeve, 1975; Doğramacı, 1989; Kurtonur et al, 1996; Kryštufek and Vohralík, 2001, 2005, 2009; Yiğit et al, 2006, 2016)
3653 photos of large and medium-sized mammals were recorded as a result of 11,868 camera trapping days (Appendix 2)
Among the 3653 records, the highest detection rates belong to Sus scrofa (29.14%), Martes spp. (20.35%), and Canis aureus (15.35%), and the detection rates of all other species constitute only 10.79% of the total detection rate (Table 1)
Summary
The Mediterranean region hosts 321 mammal species (Temple and Cuttelod, 2009), 154 of which are found in Turkey, including about 20 large and medium-sized mammals (Kumerloeve, 1975; Doğramacı, 1989; Kurtonur et al, 1996; Kryštufek and Vohralík, 2001, 2005, 2009; Yiğit et al, 2006, 2016). One in 6 (16.5%) Mediterranean mammals are threatened with extinction on a regional scale, with a further 8% assessed as near threatened (Temple and Cuttelod, 2009). About 27% of Mediterranean mammals have declining populations and 31% are stable, while for 40% the population trend is unknown; only 3% of mammal species populations are increasing (Temple and Cuttelod, 2009). Camera traps allow scientists to monitor and detect wild species that are hard
