20.500.12556/RUL-148146 Using heterogeneous camera-trapping sites to obtain the first density estimates for the transboundary Eurasian lynx (Lynx lynx) population in the Dinaric Mountains Estimating abundance of wild animal populations is crucial for their management and conservation. While spatial capture-recapture models are becoming increasingly common to assess the densities of elusive species, recent studies have indicated potential bias that can be introduced by unaccounted spatial variation of detectability. We used camera-trapping data collected in collaboration with local hunters from a transnational population survey of the Eurasian lynx (Lynx lynx) in Slovenia and Croatia, to provide the first density estimate for the threatened Eurasian lynx population in the Northern Dinaric Mountains. Population density was 0.83 (95% CI: 0.60–1.16) lynx/100 km$^2$, which is comparable to other reintroduced Eurasian lynx populations in Europe. Furthermore, we showed that baseline detection rate was influenced by the type of site used, as well as by sex of the individual and local behavioural response. Scent-marking sites had on average a 1.6- and 2.5-times higher baseline detection rate compared to roads and other locations, respectively. Scent-marking behaviour is common for several mammals, and selecting sites that attracts the targeted species is used to increase detection rates, especially for rare and cryptic species. But we show that the use of different location types for camera trapping can bias density estimates if not homogenously distributed across the surveyed area. This highlights the importance of incorporating not only individual characteristics (e.g., sex), but also information on the type of site used in camera trapping surveys into estimates of population densities. transnational population monitoring scent marking roads spatial variation of detectability sex-structured dataset spatial capture-recapture transnacionalno spremljanje populacije označevanje vonjav ceste prostorske variacije zaznavnosti spolno strukturirani niz podatkov prostorsko zajemanje prostorsko ponovno zajemanje true false true Angleški jezik Slovenski jezik Članek v reviji 2023-07-28 08:14:18 2023-07-28 08:14:30 2023-11-17 03:36:34 0000-00-00 00:00:00 2023 0 0 Str. 3199–3216 iss. 10 Vol. 32 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*15 1572-9710 10.1007/s10531-023-02646-3 156248067 RAZ_Flezar_Ursa_2023.pdf RAZ_Flezar_Ursa_2023.pdf 1 E965EE0BDC4268824C236C2F4B45A8EE 7ef9580344219fee9ae4296beff5f90d60c662399d8a0f44c03df9d178084cb3 7d98b4ab-847f-11ee-b83b-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177700 https://link.springer.com/article/10.1007/s10531-023-02646-3 1 3ff6b863-2d0e-11ee-aeaf-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=172145 Biotehniška fakulteta 0 0 0
