The influence of domestic dogs on the spatial and temporal distribution of tayra

The domestic dog (Canis familiaris) is an exotic species known to have impacts on native fauna and it may induce spatial and temporal segregation in other species as a mechanism to reduce agonistic interactions. The tayra (Eira barbara), a medium-sized, widely distributed mustelid, is one of the species that can be affected. To test this hypothesis, between 2020 and 2022, we installed camera traps in an agricultural landscape composed of a protected area, agro-livestock areas, an urban area, and several rural households. We calculated the activity patterns, their overlapping coefficients and generated models to explain the species’s occupancy and verify possible interferences. We obtained 32 records of tayras and 100 of domestic dogs. In only 8 of 73 sampling points, the two species occurred concomitantly. Activity overlap was 68%; however, at the points where both species occurred, the overlap was 43%. Tayra showed to be positively associated with forest areas, and negatively with agri..., , , # The influence of domestic dogs on the spatial and temporal distribution of tayra

## Description of the data and file structure

We obtained records of tayras and dogs using 40 camera traps between December 2020 and August 2022, totalling a sampling effort of 43,665 cameras per day. The camera traps were systematically arranged at 73 sampling points approximately 30-40 centimeters from the ground, with approximately 2 kilometers between the points. We programmed the traps to work continuously, 24 hours a day for at least 60 consecutive days.

The photographic records were extracted as information on the location of species activity, their presence and absence histories and the temporal variations that interfere with detection and the spatial variations that interfere with occupation.
