The global road network is rapidly growing associated with human economic development. This growth also entails a high toll for biodiversity, several well-documented negative impacts on different species. However, there still great lack of knowledge about the effects roads persistence wildlife populations. Here, we aimed to summarize our current this topic, based systematic reviews. We found that only small proportion studies (8%) focused population persistence. Most these were large mammals and performed in high-income countries. Furthermore, works studied 2% those species identified by IUCN Red List as threatened roads. Overall, results show are far from understanding how affect long-term viability populations inhabiting road-effect zones. Addressing challenge will require modifying conceptual perspective, short-term studies, single sections focusing landscape scale, strive obtain empirical data support sound analyses assess survival populations, namely information required perform approaches such analyses. highlight some key reviews have addressed conservation concern population-oriented approaches.
