Resumen:
tWe studied the daily activity pattern and habitat use of the lowland tapir Tapirus terrestris and their rela-tionship with environmental and anthropic variables. We used photographic records of tapirs obtainedduring five camera-trap surveys conducted in three areas of the Atlantic Forest of Argentina that differin their protection against poaching. The daily activity pattern was analyzed with circular statistics andlinear regression. The effect of protection against poaching and environmental variables on habitat useof tapirs was analyzed using occupancy modeling. Tapirs were nocturnal all year round, with 89% of therecords between 1800 h and 0700 h. The proportion of nocturnal records and the recording rate did notchange with mean daily temperature. The daily activity pattern of tapirs was not affected by the sexof the individuals, the lunar cycle or the protection level of the area. The probability of detecting tapirsincreased with the distance to the nearest access points for poachers and decreased with the abundance ofbamboo in the understory and increasing trail width. The probability of use of an area by tapirs increasedwith increasing protection against poaching and distance to the nearest access points for poachers. Theseresults suggest that poaching is one of the factors with significant effect on habitat use by tapirs but noton their daily activity patterns.
