Abstract
We report the roadkill of a jaguar in one of the longest highways in Brazil (BR-101), in the stretch where this road crosses one of the most important Atlantic Forest remnants in the country: the Linhares-Sooretama block. The jaguar population present in this area represents the very last in entire Espírito Santo state. There is an approved project to the lines duplication of the entire BR-101 Highway and the company responsible by the work has already started the first activities in the state. However, there is no environmental impact assessment already done neither planning for the implementation of measures to avoid or reduce the roadkill risk in the region. Thus, to minimize the impacts associated with the BR-101, we do not recommend its lines duplication along the 15 km stretch traversing the Linhares-Sooretama block. In addition, alternatively, we suggest the deviation of the current route of the BR-101 Highway or the construction of overpasses to fauna in the most critical points, interspersing these overpasses with electronic speed monitoring devices and warning and educational plates.
Highlights
Roads cause alterations to landscape as a result of fragmentation and habitats deterioration, resulting in several negative effects on animal and plant communities, which affect the integrity of terrestrial and aquatic ecosystems (Trombulak and Frissell, 2000)
Roadkill may have a substantial effect on the demography of the populations most often affected by collision with vehicles (Trombulak and Frissell, 2000) and have become a growing problem in recent years (Baskaran and Boominathan, 2010), representing an even greater threat to threatened species whose populations are restricted to a small number of individuals frequently in contact with roads
Jaguar roadkill in Atlantic Forest. This communication reports the roadkill of a jaguar on the BR-101 Highway, in a sector where this road crosses the two largest protected areas in the state of Espírito Santo, southeastern Brazil

A brief review about this issue and the proposition of measures to minimize the impacts of roadkill on that sector of BR-101 are presented and discussed
