“…A possible explanation for these mixed results is that the temporal resolution of the traffic volume data set may not have matched when a particular species is most prone to WVCs. For example, Shepard et al (2008) report that the time of day when snakes are most active does not coincide with daily traffic peaks so it is possible that traffic volume is a significant factor on snake mortality over shorter time scales than what they examined. also document mixed results from studies analysing the relationship between traffic volume and wildlife-vehicle collisions, which they attribute to the use of unsuitable temporal scale domains for explanatory variables.…”

“…Almost all species documented in this study included at least one individual that had been killed by local people in Rio Tinto. Second, snakes must frequently cross roads in urban areas and are easy targets for drivers (Bonnet et al 1999, Shepard et al 2008b). Third, snakes in urban areas are subject to higher levels of parasitic infection and predation by exotic cats, dogs and chicken (Greene 1997).…”

“…Third, snakes in urban areas are subject to higher levels of parasitic infection and predation by exotic cats, dogs and chicken (Greene 1997). Finally, habitat modification, loss, and fragmentation in urban areas can reduce food resources, reproduction sites, and gene flow, leading to local extinctions (Shepard et al 2008b).…”

Abstract:The Atlantic Forest of Brazil is one of the most biologically diverse regions in the world, but also one of the most highly threatened, with only around six percent of its original cover remaining. Despite the increase in the number of studies on the ecology of Brazilian snakes during the last two decades, there are still very few works on snake assemblages in the Northeast region and almost nothing about snakes inhabiting urbanized areas in Atlantic Forest domain. Herein we describe the snake assemblage from the urban area of Rio Tinto city in Paraíba State, Northeast Brazil. We present data on composition, distribution and some natural history. Also, we compare the snake diversity of the urban area with the diversity in two nearby natural patches. We recorded 161 individuals of 25 species in 16 genera from the urban area of Rio Tinto and the most common species were Helicops angulatus, Bothrops leucurus, Epicrates assisi, and Philodryas patagoniensis. Most snake species were non-venomous, but some venomous snakes were abundant in the urban area and people must be cautious when dealing with these. Rarefaction curves did not reach stability and new species should be added to the Rio Tinto snake list in future studies. Resumo: A Mata Atlântica é uma das ecorregiões mundiais que apresenta maior diversidade, entretanto é também uma das mais ameaçadas com apenas seis por cento de sua cobertura vegetal original preservada. Apesar do aumento no número de trabalhos sobre ecologia de serpentes brasileiras durante as últimas duas décadas, ainda são poucos os estudos sobre as taxocenoses de serpentes da região Nordeste do Brasil e praticamente nada está publicado sobre serpentes encontradas em áreas urbanas na Mata Atlântica nordestina. Este trabalho apresenta uma descrição da taxocenose de serpentes da área urbana de Rio Tinto, cidade localizada no litoral norte da Paraíba. O trabalho focou a composição, distribuição e alguns aspectos da história natural das espécies de serpentes. Além disso, a diversidade de serpentes encontrada na área urbana foi comparada à de outras taxocenoses de serpentes presentes em unidades de conservação nas proximidades de Rio Tinto. Foram registradas 161 serpentes de 25 espécies e 16 gêneros para a área urbana de Rio Tinto, sendo as espécies mais comuns Helicops angulatus, Bothrops leucurus, Epicrates assisi e Philodryas patagoniensis. A maioria das espécies não são venenosas, entretanto, algumas serpentes venenosas apresentaram grande abundância e a população local deve ser cuidadosa ao lidar com estas serpentes. As curvas de rarefação não atingiram a assíntota e novas espécies devem ser registradas para Rio Tinto em estudos futuros. Palavras-chave: serpentes, Paraíba, herpetologia urbana, áreas antrópicas.

“…in Canada, road mortality is now considered a major threat to the persistence of endangered species, particularly reptiles (e.g., Row et al 2007). Road mortality surveys have been used in areas of ecological importance to identify the nature and extent of wildlife road mortality (ashley and Robinson 1996; Vijayakumar et al 2001;smith and Dodd 2003;Langen et al 2007;Coelho et al 2008;shepard et al 2008), and to measure the effectiveness of mitigation measures (Dodd et al 2004;aresco 2005;BaxterGilbert et al 2015).…”

the ojibway Prairie Complex in Windsor contains the largest protected tallgrass prairie ecosystem in ontario and supports numerous species at risk. Despite its ecological significance, it is crossed by multiple high-traffic roads. Road mortality is a major threat to endangered species in Canada, particularly reptiles. the main goal of this study was to describe the nature and extent of vertebrate road mortality, with a focus on reptiles, on roads bisecting the ojibway Prairie Complex, and the Greater Park ecosystem, in Windsor and Lasalle, ontario. a systematic road mortality survey was conducted by bicycle along seven roads (12.5 km) in 2010, 2012, and 2013. also, opportunistic observations (n = 103) spanning over 30 years were assembled from a variety of sources. in total, 2083 vertebrates (49 species), including 446 reptiles (11 species), were recorded "dead on road" during systematic surveys. the highest diversity of reptiles was recorded on Matchette Road, whereas the highest rate of reptile mortality was recorded on Malden Road. Reptile species at risk were killed on all roads surveyed. Combining systematic and opportunistic data, we found seven reptile species at risk: Butler's Gartersnake (Thamnophis butleri), eastern Foxsnake (Pantherophis vulpinus), eastern Massasauga (Sistrurus catenatus catenatus), Blanding's turtle (Emydoidea blandingii), eastern Musk turtle (Sternotherus odoratus), northern Map turtle (Graptemys geographica), and snapping turtle (Chelydra serpentina). Reptile road mortality "hotspots" occurred where each road is intersected by a naturalized utility right-of-way. our results can be used to focus mitigation efforts in space and time to reduce mortality rates and enhance connectivity in the ojibway Prairie Complex and Greater Park ecosystem.
