“…Attractants such as baits (food reward) and lures (non-food reward) are often used in carnivore studies to increase encounter events (Schlexer 2008). However, responses to attractants can vary greatly among species, making choice of attractants an important aspect of study design in multi-species studies (Du Preez et al 2014, Ferreira-Rodríguez and Pombal 2019, Buyaskas et al 2020, Holinda et al 2020. Seasonal timing of the survey can influence inference regarding habitat use or activity patterns (Kays et al 2020) and affect encounter frequencies, particularly for species that hibernate or exhibit seasonal differences in density (e.g.…”

“…We addressed this issue by using bait to maximize species detection and minimize the bias in occupancy estimate. Using bait to lure species has been successfully applied in several studies, especially for rare or species with low detection rate, to maximize detection rate (Kowalski et al 2015;Pacifici et al 2016;Ferreira-Rodríguez and Pombal 2019;Kays et al 2020). Further, our sampling duration, eight weeks, was longer than the sampling duration of other studies.…”

The relationship between landscape features and domestic species on the occupancy of native mammals in urban forests

2021

Landscape features such as roads, hiking trails, and forest edge are prevalent features of urban forests. These features can negatively influence biodiversity through fragmentation and facilitate the penetration of invasive species, particularly predators such as domestic dogs and cats. This study examined how these landscape features affect the distribution of native and domestic mammals and how domestic species affect the occupancy and activity patterns of native mammals. To this end, we conducted camera trap surveys in forested urban and suburban parks in Indiana and Kentucky, USA, to record the presence of native species (deer, raccoons, coyote, and opossums) and non-native predators (domesticated cats and dogs) in relation to distance to nearest roads, hiking trails, and forest edge. We found negative correlations between proximity to roads, hiking trails, and forest edge and the occupancy of the native species with this effect extending up to 300 m. We also found evidence that the presence of dog and cat was negatively correlated with the occupancy for all native species. We recommend park management consider the impact of roads, hiking trails, and forest edge when designing parks and the enforcement of dog leash regulations for the conservation of large mammals in urban parks.

“…Se utilizó como atrayente un pedazo de piel de conejo apto para consumo humano empapado en su propia sangre, con el que se hizo un rastro de unos 30 m en todas direcciones desde la estación de fototrampeo para aumentar su radio de acción. La elección de este se basó en experiencias propias, en las que se testaron distintos atrayentes en un área con presencia conocida de la especie, algunos de ellos empleados habitualmente en muestreos de este tipo aunque con resultados contradictorios (Barrull et al 2014, Ferreira-Rodríguez & Pombal 2019, como el pollo fresco o el aceite de sardinas en lata (Kucera et al 1995b, Sirén et al 2016, O´Brien et al 2018, resultando la piel de conejo el más eficaz a la hora de detectar la presencia de martas.…”

“…Para minimizar la posible interferencia producida por otras especies de carnívoros, como zorros Vulpes vulpes (Linnaeus, 1758), tejones Meles meles (Linnaeus, 1758) o perros Canis familiaris (Linnaeus, 1758), las cámaras y los atrayentes olorosos se instalaron a dos metros del suelo sobre árboles en pie (Kucera & Barrett 1993, Kucera et al 1995b, separados de 2 a 3 m para reducir los fallos en la detección de la especie (Burki et al 2010, Ferreira-Rodríguez & Pombal 2019.…”

Pine marten Martes martes is a medium size mustelid that inhabits well-conserved forests of the northern Iberian Peninsula. Currently, the distribution and ecology of the species in the Iberian Peninsula is poorly known. In this work, 27 UTM 10x10km grids in the province of Ourense were sampled using camera-trapping techniques, with the aim of increasing knowledge about the distribution of the species in Galicia. The presence of pine marten was confirmed in 18 of the surveyed grids, which increases the species´ known distribution area by 21% in this community and by 62% in Ourense province, confirming camera-trapping specific survey as a highly effective method to know the distribution of elusive species such as the pine marten.
