“…In a two-year study, involving 260 km of highways and 314 km of national roads, Grilo et al (2009) found that only 2.5% out of 806 detected casualties of carnivores were of polecats and suggested that this might be positively correlated with the species abundance in the region. This conclusion agrees with both Grilo et al (2008), in which from a total of 1,940 track records of carnivores detected in highway culverts and underpasses (marble dust track pads) only one corresponded to a polecat, and Mateus et al (2010), a study conducted in the same area, to assess cost-effectiveness of monitoring methods of carnivore use of drainage culverts, in which not a single polecat was recorded.…”

Ecology and conservation of the polecat Mustela putorius (Linnaeus, 1758) ABSTRACTIn Portugal, the current status of the European polecat Mustela putorius (Linnaeus, 1758) is Data Deficient but, although apparently widespread in the country, empirical evidence suggests a population decline. The present review summarises information from published studies and grey literature concerning the species' distribution, ecological requirements and the negative impacts of anthropogenic pressures. In southern Portugal, polecats seem to be strongly associated with riparian habitats and specialised in the consumption of lagomorphs. Main threats to the species in Portugal are habitat degradation due to agricultural intensification, decline of prey populations, direct persecution, and road mortality. Further research is urgently needed to accurately map the occurrence of the polecat and assess the current trend of its populations, so that conservation and management actions can be properly applied. Ongoing studies are expected to provide new insights into patterns of time and space use, genetic structure and putative hybridisation with domestic ferrets, and interspecific interactions with the other semi-aquatic carnivores of the Portuguese fauna, the otter Lutra lutra (Linnaeus, 1758) and the American mink Neovison vison (Schreber, 1777). Conservation actions should include the recovery and preservation of the habitats for polecats and their prey, promotion of non-intensive farming and restricted use of pesticides, surveillance of predator control activities, enforcement of mitigation measures in human-altered landscapes, and monitoring of hybridisation with ferrets. The implementation of these measures should increase polecat chances of persisting in Portuguese landscapes and, ultimately, would benefit the whole carnivore community. KEY WORDS:European polecat, ecology and conservation, literature review, Mustela putorius, Portugal. RESUMENLa información actual sobre el estado del turón Mustela putorius (Linnaeus, 1758) en Portugal es escasa; sin embargo, a pesar de que parece estar ampliamente distribuido por todo el país, evidencias empíricas parecen indicar un disminución de la población. La presente revisión es un compendio de toda la información disponible en artículos y literatura gris sobre su distribución, ecología y el impacto que la actividad humana ha ejercido sobre la especie. En el sur de Portugal, el turón parece estar fuertemente asociado a zonas ribereñas y haberse especializado en el consumo de lagomorfos. Las principales amenazas a esta especie en Portugal son la degradación de su hábitat debido a la intensificación de la agricultura, la disminución de las poblaciones de sus presas, la persecución directa de animales, y la muerte accidental en carreteras. Por lo tanto, es necesaria más investigación que permita determinar la incidencia y tendencias de las poblaciones de turón, con el fin de poder aplicar e implementar eficazmente diferentes programas de conservación y gestión. Se espera que los estudios en...

“…For instance, little is known about the consequences of vibration and noise on biodiversity living adjacent to the railway bed (see Chap.6). Also, studies are needed on the relative cost-effectiveness of different management tools and mitigation measures to help reconcile environmental protection and socio-economic demands (see, e.g., Andreassen et al 2005;Ford et al 2009;Mateus et al 2011). The potential positive impacts of railways also need to be better explored, including in particular the prospective for the right-of-way to act as a shelter for biodiversity (see Chap.…”

Predicting is very difficult, especially about the future, attributed to Niels Bohr.Abstract As societies realise the importance of maintaining biodiversity and, accordingly, acknowledge the need for monitoring, minimizing and compensating the impacts of socioeconomic activities, including transportation, more scientists will be called to address these societal challenges. Railway Ecology is emerging in this context as a relatively new field to identify and provide solutions to the specific environmental problems associated with the building and operation of railways, particularly their impacts on wildlife. This is an interdisciplinary field that uses and draws methods from other disciplines, ranging from ecology and genetics, to statistics and computer simulations. Here, we summarize the guidelines to address railway-related biodiversity conservation problems as they were identified in the several chapters of this book, and recommend lines for future research.

“…One method that allows for the evaluation of how water affects the extent culverts are used by carnivores to cross roads is video-surveillance (Stewart et al 1997;Mateus et al 2011). This method also has the advantage of being able to record an animal's behavior towards the culvert itself (see Hardy et al 2003;Dodd et al 2007), which can yield valuable insights regarding culvert design as a road mitigation measure.…”

Drainage culverts are known to be used by a diverse number of species. To date, most studies looking at culvert usage have been restricted to the dry season. This seasonal bias has limited our understanding of how different species respond to culverts and, consequently, our ability to find effective ways to promote the use of culverts as aids to species movement. The main goal of this study was to examine the role of highway culverts for mesocarnivores throughout the year. We addressed (1) the seasonality of culvert use, (2) the relative importance of culvert structure, highway features, and surrounding landscape on culvert use, (3) the influence of the water depth and cover on culvert use, and (4) the effect of culvert structure on individual behavior. Fifteen culverts were monitored along 2 highways in southern Portugal using video-surveillance cameras and marble dust for 10 consecutive days per season. We used generalized linear mixed models to determine which factors most affected the culvert use and behavior by mesocarnivores. Our results highlight the effect of seasonality and water on culvert use. Culvert use was positively related with species activity throughout the year. All species (except otters (Lutra lutra)) were less likely to use culverts that contained water more than 3 cm deep or covering more than 70 % of the culvert base. Based on our results, future surveys and culvert retrofit design should address (1) the importance of seasonality in the interpretation of results and (2) the complementarity of culvertspecific features (water, ledges, and naturalization).
