Abstract

We present new records of two threatened canid species, the bush dog (Speothos venaticus) and the maned wolf (Chrysocyon brachyurus), within and in the vicinity of Iguaçu National Park, Paraná, Brazil. These records were obtained through camera trap monitoring conducted between 2018 – 2020 and a wildlife rescue operation outside the park. The bush dog record was the first in a decade of camera trap monitoring, encompassing 20,297 trap days. This effort is comparable to that expended in detecting the species in other areas of the Atlantic Forest. The maned wolf records in the Atlantic Forest were unexpected, given the species’ apparent avoidance of this habitat type. This presence may be attributed to significant landscape transfor- mations, creating open areas conducive to the maned wolf’s dispersion within the Atlantic Forest. These records highlight the importance of investigating the dispersal behaviors of the bush dog and the maned wolf in this region to understand the impact of human-altered landscapes on the geographical distribution of these two canids. These new records within and on the border of the Iguaçu National Park assume particular significance for enhancing and coordinating conservation initiatives for these species and establishing public policies for their conservation.
