Abstract. Management and conservation strategies for endangered species require information on their temporal and spatial behavioral and habitat use relationships. We evaluated activity patterns and resource selection of black bears in northwestern Mexico. We surveyed 29 localities with 1450 camera traps stations from 2009 to 2013 in the states of Sonora and Chihuahua, Mexico. In each locality, we calculated the proportion of diurnal, nocturnal, and crepuscular activity through a kernel density estimator based on the time of independent photographic events, and we built a beta regression between diurnal density and annual temperature, seasonal rainfall (SR), human density, road density, daylight hours, season, and management type. To evaluate resource selection, we built a binomial logistic regression model incorporating Normalized Difference Vegetation Index (NDVI), mean and coefficient of variation of annual temperature, human population density (PD), terrain roughness, and season. Black bear activity was primarily diurnal with a bimodal tendency around sunrise and sunset. Diurnal activity (between sunrise and sunset) was positively influenced by daylight hours, SR, and private reserves and negatively influenced by anthropogenic factors. Resource selection was positively influenced by the coefficient of variation in temperature and NDVI and negatively associated with average annual temperature, PD, and terrain roughness. Activity patterns and resource use were similar to other regions in North America. However, temperature was one of the main factors influencing black bear activity and resource selection in our study areas and should be considered when developing management plans given projected increases in temperature expected under climate change scenarios. We present the first work of its kind for northwestern Mexico and considered it as an important component in future survey and management protocols for the species in the southern portion of its distribution.

“…This approach, however, is not applicable to the many mammal species that lack any distinctive markings. On the other hand, the capacity of camera-traps to continuously monitor animal activity has enabled researchers to describe daily activity patterns with a level of detail not possible previously [14][15][16].…”

Baird´s tapir (Tapirus bairdii) is one of the most emblematic mammalian species from Mesoamerica. Due to its level of evolutionary distinctiveness and anthropogenic threat this species was recently ranked in 34th position, in terms of its urgency for conservation, among more than 4,000 species of mammals assessed by experts from the Zoological Society of London. Despite its evolutionary and conservation relevance there remain important gaps in knowledge of the basic ecology of this species. Based on camera-trapping data, we estimated Baird´s tapir abundance and analyzed its patterns of daily activity and preference for different altitude intervals in El Triunfo Biosphere reserve, one of the last strongholds for this species in southern Mexico. We also applied a recently developed method (Random encounter model) to estimate tapir density without the need of individual identification. Tapir relative abundance was: 1.3 events/100 camera-trap days and density: 0.12 ind./km 2 . Tapir activity concentrated around dusk (χ 2 = 21.18, P<0.01) and use of mid-altitude areas was preferred (χ 2 = 49, P < 0.001). This study provides data on the ecology of the species and insights on study methods that can have a direct positive impact on its management and conservation.Keywords: density estimation, camera-trapping, cloud forest, mammal threat, daily activity Resumen El Tapir o Danta centroamericana (Tapirus bairdii) es una de las especies de mamífero más notables de Mesoamérica. Debido al grado de amenaza que experimenta y a que representa una línea evolutiva muy distintiva, esta especie fue recientemente colocada en el lugar 34, en términos de la prioridad de su conservación, entre más de 4,000 especies de mamíferos evaluados por expertos de la Sociedad Zoológica de Londres. A pesar de esto, persisten importantes vacíos en el conocimiento de la ecología básica de esta especie. Con base en un estudio de foto-trampeo estimamos la abundancia de T. bairdii y analizamos sus patrones de actividad, a lo largo del día, y de uso de sitios a lo largo de un gradiente altitudinal en la Reserva de la Biosfera de El Triunfo, uno de los últimos refugios de la especie en el sureste de México. Asimismo, aplicamos un método recientemente desarrollado (Modelo de encuentros aleatorios) para estimar la densidad del tapir sin la necesidad de realizar identificación individual. Los valores estimados de abundancia relativa de la especie y densidad fueron: 1.3 eventos/100 días cámara-trampa y 0.12 ind./km 2 . La actividad del tapir se concentró alrededor del anochecer (χ 2 =21.18, P<0.01) y en la zonas de altitud media (χ 2 = 49, P < 0.001). Este estudio presenta información sobre la ecología básica de la especie y sobre aspectos metodológicos de su estudio que pueden impactar de manera positiva las prácticas para su manejo y conservación.Palabras clave: estimación de densidad, foto-trampeo, bosque de neblina, mamíferos amenazados, actividad diaria.

“…A number of researchers have stated that the lynx shows a probable distribution in this region (Kumerloeve, 1967;Turan, 1984;Kryštufek and Vohralík, 2009). Lynx were recorded from west of Ankara as the closest locality to Zonguldak (Ambarlı et al, 2010;Mengüllüoğlu, 2010;Akbaba and Ayaş, 2012). Can (2008) did not detect this species in a photo trap study performed in Yenice Forest close to Zonguldak Province.…”

“…Despite there being many studies on Turkish mammals, information on the ecology and distribution of many of the mammal species is quite inadequate (Can and Togan, 2004;Can, 2008;İlemin, 2009;İlemin and Gürkan, 2010;Soyumert, 2010;Soyumert et al, 2010;Akbaba and Ayaş, 2012;Albayrak et al, 2012;İlemin, 2014;Çoğal and Sözen, 2017). Though some records for large and mediumsized mammal species for Zonguldak Province have been provided by some researchers (Kumerloeve, 1967;Kryštufek and Vohralík, 2009), no detailed studies have occurred and most of the distribution maps were estimated without any definite records.…”

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 km 2 , 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.
