Roads, while crucial for human development and economic growth, pose significant threats to biodiversity. Large-scale road risk assessments are essential for guiding infrastructure planning, particularly in identifying areas to avoid new construction or prioritizing regions for mitigation where road networks are already established. However, conducting comprehensive assessments is challenging in regions with li...
Approximately 65% of primate species are facing extinction, with threats including the impacts of linear infrastructures such as roads, railways, and power lines, associated with habitat loss and fragmentation, direct and indirect mortality, and changes in animal behavioral patterns. Nevertheless, this is an often-overlooked topic in primatology, and there is limited information on which regions and species are...
We present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the assessment of invasion risks, formulation of preventive and managemen...
Systematic road-kill surveys are useful to study the impact of roads on wildlife. However, they are time-and budget-consuming, so the use of non-systematic data in road ecology is currently gaining popularity (for instance, by environmental consultants). Some data sources such as atlases (i.e., compilations of species records from a given region), which can include non-systematic and citizen-science data, can e...

The global road network is rapidly growing associated with human economic development. This growthalso entails a high toll for biodiversity, with several well-documented negative impacts on differentspecies. However, there is still a great lack of knowledge about the effects of roads on the persistenceof wildlife populations. Here, we aimed to summarize our current knowledge on this topic, based onsystematic re...
Building trust in science and evidence-based decision-making depends heavily on the credibility of studies and their findings. Researchers employ many different study designs that vary in their risk of bias to evaluate the true effect of interventions or impacts. Here, we empirically quantify, on a large scale, the prevalence of different study designs and the magnitude of bias in their estimates. Randomised de...
