“…It is important to note that variations in the results may be due to detectability rate (Teixeira et al 2013), sample effort, duration of studies, type and location of roads, and seasonality. In the present study, except for Dasyprocta, the recorded species were also found in studies conducted in the states of Santa Catarina (Cherem et al 2007), Mato Grosso (Melo & Santos-Filho 2007), Rondônia (Turci & Bernardes 2009), Goiás (Cunha et al 2010), and Mato Grosso do Sul (Cáceres et al 2012).…”

Habitat fragmentation due to transport infrastructure, such as highways, is receiving growing concern due to deleterious consequences of roadkill, a consequence of animal-vehicle collisions. This study was conducted on a 115 km section of the highway BR-242 between the Peixe Angical Hydroelectric Power Plant and Gurupi town, Tocantins state, Brazil. During twelve months, records of medium and large-sized mammals' roadkilled by vehicle collisions were weekly acquired. Photographic records, date and place of occurrence were obtained for each roadkilled animal. We also propose new indexes to evaluate roadkill rates. In total, 18 species, 17 genera, 10 families, and six orders were recorded. The species with the highest number of registers were: Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla, Procyon cancrivorus, Nasua nasua and Dasyprocta leporina, corresponding to 73.5% of roadkills. The curve of species accumulation showed no tendency for stabilization. The results showed that the roadkill indices were 0.003 species/km; 0.009 individuals/km; 0.375 species/monitoring campaign; 1,021 individuals/monitoring campaign; 306,667 kilometers traveled/hit species, and 115,00 kilometers traveled/animal. Seven species recorded are considered threatened: Chrysocyon brachyurus, Leopardus pardalis, Leopardus wiedii, Lycalopex vetulus, Myrmecophaga tridactyla, Puma concolor, and Puma yagouaroundi.

“…The high number of road-killed Crotalus durissus species (N = 128) and Salvator merianae (N = 102) can be explained by the fact that they are species commonly found and adapted to open and anthropized areas, such as residential and commercial regions along roadsides. On the other hand, as in several other studies carried out in Brazil (Coelho et al, 2008;Kunz & Ghizoni-Jr, 2009;Turci & Bernarde, 2009;Abra et al, 2019;Ascensão et al, 2021) larger animals were more represented in our records of road-kills and this effect can be explained by the monitoring speed (50 km/h) and the means of transport used for monitoring (car assistance), a general standard used in our collection methodology and in several other studies (Enge & Wood, 2002;Taylor & Goldingay, 2004;Coleman et al, 2008;Delgado et al, 2019). These choices likely result in lower detection of small animals as reported in other studies that used bicycles and/or lower speed during monitoring (Pracucci et al, 2012;Rosa et al, 2012;Pinheiro & Turci, 2013;Santos et al, 2016;Wang et al, 2022), indicating that monitoring carried out with the help of cars can generate biased results for large animals.…”

March or Die: road-killed herpetofauna along BR-040 highway, an ancient road on the Atlantic Forest from Southeastern Brazil

et al. 2023

The construction of highways is responsible for access to previously protected areas, resulting in changes in landscape and dynamics of the animal populations that live in these areas. These enterprises are the major responsible for the mortality of wild animals, surpassing hunting and even the trafficking of animals. The objective of this study was to make a list that reflects the diversity of amphibians and reptile’s road-killed along the BR-040, a highway that crosses the threaten lowland Atlantic Forest in Southeastern region of Brazil, including the use of microhabitats, lifestyle, activity pattern, reproductive cycles, and possible rare or endangered species. The study area consists of 180,4 km of highways. Monitoring began in 2006 and continues to the present day. A total of 1,410 individuals from 60 species were recorded in this study. The reptiles were more frequent in number of individuals and species. The commonest species recorded were Crotalus durissus and Dipsas mikanii. We have registered a single endangered species: Ranacephala hogei. The highest rates of road-kill were recorded during the wet season. Road-kills of fauna is a major threat to species, studies are of great importance to define plans that seek to mitigate the effects generated by these enterprises.

“…Espécies abundantes, de pequeno porte e hábito noturno seriam as mais atropeladas, enquanto que espécies de grande porte, principalmente diurnas e crepusculares, exibiriam baixas taxas de atropelamento ou tenderiam a não ser atropeladas (Cáceres et al 2010, Cáceres 2011, Bueno et al 2015, Brum et al 2018. Para os fatores extrínsecos, variações temporais e espaciais foram as mais investigadas, e mostraram que o período chuvoso do ano, distância de centros urbanos e proximidade de cursos d'água e grandes fragmentos florestais contribuíram com um aumento no número de animais atropelados (Coelho et al 2008, Turci & Bernarde 2009, Cáceres et al 2012, Ferreira et al 2014, Bueno et al 2015.…”

Efeito Da Paisagem Sobre Os Atropelamentos De Mamíferos De Médio E Grande Porte No Sul De Goiás, Brasil

As rodovias têm sido apontadas como uma das principais causas antrópicas que influenciam na mortalidade da fauna silvestre. Aqui, nós investigamos o efeito da paisagem sobre a comunidade de mamíferos atropelados em um trecho de 50 km da rodovia GO-164, sul de Goiás, Brasil. Nós dividimos o trecho em 10 quadrantes de 25 km² cada (unidades amostrais), nos quais obtivemos a abundância, riqueza e composição de mamíferos atropelados em resposta a dois preditores da paisagem: distância para o cursod'água e percentual de cobertura vegetal nativa. Encontramos que a riqueza de mamíferos atropelados é maior, quanto menor a distância para o curso-d'água, e que a composição da fauna de mamíferos atropelados é influenciada pelo percentual de cobertura de vegetação nativa na paisagem. Concluímos que há uma variação espacial dirigida pelas características da paisagem, que influenciam na ocorrência de atropelamentos de mamíferos.Palavras-chave: distância do rio, ecologia de estradas, quantidade de habitat, riqueza de espécies EFFECTS OF LANDSCAPE ON ROADKILL OF MEDIUM AND LARGE-SIZED MAMMALS IN SOUTHERN GOIÁS, BRAZIL.The highways have been identified as one of the main anthropogenic causes that influences the mortality of wildlife. Here, we investigated the effects of landscape structure on the roadkill mammal species in a section of 50-km of the highway GO-164, southern Goiás, Brazil. We divided the section of 10 quadrants of 25 km² (sampling units), in which we measured abundance, richness, and species composition of roadkill mammals in response to two predictors of the landscape: distance to the river and percentage of habitat amount. We found that the richness of roadkill mammals is higher closer to the river and that roadkill mammalian species composition is affected by the habitat amount in the landscape. We conclude that there is a spatial variation driven by the landscape characteristics, which influences the occurrence of mammal roadkill.
