Furthermore, because of the undeniable difficulty of small\u2010mammal track identification, most biologists usually carry out general surveys without species recognition. We hypothesized that general surveys traditionally used for monitoring WRC by small mammals may be biased because the degraded habitats along roads are mainly used by generalist and not specialist species. For this reason, we compared the results of a general small\u2010mammal survey with those from a species\u2010specific one, focusing on 3 study species: 1 habitat generalist (North American deer mouse [Peromyscus maniculatus]), 1 forest specialist (southern red\u2010backed vole [Myodes gapperi]), and 1 prairie specialist (meadow vole [Microtus pennsylvanicus]). We sampled along 4 types of WCS (overpasses, open\u2010span underpasses, and both elliptical and box culverts) in Banff National Park (Canada), by placing footprint track tubes along the WCS, and as a reference in front of their entrances (mainly located in roadside grasslands) and in the surrounding woodlands. Using the traditional general survey, we did not detect significant differences in small\u2010mammal presence among WCS and reference sites. In contrast, species\u2010specific surveys showed that only the deer mouse (a generalist species) consistently used the WCS. The deer mice did not show preferences for any WCS type, whereas the specialist species (voles) used only overpasses. Therefore, general surveys used without species identification can underestimate the value of WCS for specialist small mammals, with relevant conservation implications. As a consequence, we recommend species\u2010specific surveys of WCS suitability for small mammals. We also suggest improving the habitat (or at least the cover availability) in the WCS and along the space between them and the surrounding environments to increase WCS suitability for specialist species. \n Palabras clave: Mammal", "notes_translated": {"en": "The use of wildlife road\u2010crossing structures (WCS hereafter) is less monitored for small mammals than for more emblematic species.
