Resumen:
The increase in human road networks has become a threat to biodiversity. Roads are mortality blackspots, which accumulate daily carrion from roadkill in quantities that are difficult to quantify. This carrion availability may be an opportunity as a food resource for scavenger species, but only for those able to cope with a highly disturbed and risky traffic environment. Here we designed a field experiment simulating the roadkill scenario to reveal which species take advantage of this resource in semiarid habitats of central Argentina. We artificially placed carcasses of the species more frequently found road-killed in the area, the European Hare (Lepus europaeus). We set 12 carcasses next to the road (
