“…Nevertheless, whereas road‐kill survey studies are well represented in the currently growing Latin American road ecology, little is known about the effects of roads on reptiles, especially when compared to other terrestrial vertebrates (Colino‐Rabanal & Lizana, 2012; Oliveira et al, 2020; Pinto et al, 2020). This disparity could be explained by issues such as lower carcass detectability and higher removal rates (e.g., by predators and scavengers), combined with sampling designs focused on medium‐to‐large‐sized vertebrates (Barrientos et al, 2018; Santos et al, 2011; Silva, Crane, et al, 2021; Teixeira, Coelho, Esperandio, & Kindel, 2013), and the fact that collisions with larger animals present greater risks to the economy and human health (Abra et al, 2019).…”

Reptiles are an understudied group in road ecology, despite evidence of their high vulnerability to road mortality. Recently, trait‐based models have been demonstrated to be valuable tools for explaining and predicting road mortality risks for birds and mammals. The present study aimed to apply such models to reptiles for the first time. We fitted eight random forest regression models, controlling for different survey design variables, to explain 782 empirical road‐kill rates for Brazilian reptiles and selected the best‐performing model to predict road mortality risks for 572 continental species. The results showed that species that are habitat generalists, omnivorous, viviparous, cathemeral, and have intermediate clutch or litter sizes are at a higher risk of being road‐killed. The relationships for other traits included in our models were uncertain, but our findings suggest that population density and species‐specific behavioural responses to roads and traffic may play an important role in road mortality risks. Geographical location and survey design variables (especially sampling speed and sampling time) were more important in explaining the variance of the empirical road‐kill rates than any of the tested ecological and functional traits. Besides adding evidence of the vulnerability of the Amazon region to vertebrate road‐kills, this study highlights some similarities between the relationships identified here and those found for birds and mammals (such as with body mass and habitat breadth). We also corroborate that trait‐based models are useful tools to aid in conservation efforts but indicate that they can be biased by the methodologies used to collect empirical data. Future road‐kill surveys should therefore use methods specifically designed for reptiles and estimate both observer efficiency and carcass removal rates.

“…The increase in publications that surveyed wildlife roadkill reflects the increased interest in understanding and resolving the problem in Brazil. There are three reviews that point to the growing trend of studies on road ecology and wildlife roadkill in Brazil over the last two decades (Bager et al 2007;Bager and Fontoura 2012;Oliveira et al 2020). Currently Brazil has more publications on the subject than any other country in Latin America (Pinto et al 2020) and ranks third in the world for productions on road ecology (Oliveira et al 2020).…”

Currently Brazil has more publications on the subject than any other country in Latin America (Pinto et al 2020) and ranks third in the world for productions on road ecology (Oliveira et al 2020). The greater number of roads surveyed in the vicinity of PAs is a positive point for the country, coinciding with a need pointed out by Bager et al (2016), i.e., to understand the impacts of road structures in areas that are essential for biodiversity conservation.…”

“…These descriptive data can be of great importance for the area, especially in a country like Brazil that has a large land area. However, there is a need to understand the interactions between roads, animals and plants (Oliveira et al 2020). Studies that use spatial analysis to identify roadkill hotspots, for example, despite being very important, should be seen as basic works to suggest where the parameters of influence of roadkill can be analyzed (Pagany 2020).…”

Roads are responsible for great biodiversity loss, especially in protected areas (PAs). Thus, considering the great risk of roads to PAs and the lack of knowledge about these areas, we aimed to analyze the scientific production on wildlife roadkill in Brazil and compare the studies that surveyed roads with and without PAs. We searched for papers in five databases: SciELO, Google Scholar, Reet Brasil, Scopus and Plataforma Lattes. Studies considered to be near PAs (PPA) collected data within a radius of 1km of PAs and the other studies were considered to have no PA (NPA). We found 126 studies that surveyed wildlife roadkill in Brazil, of which 57% are PPA. Publications on wildlife roadkill have increased in recent years, with a greater number of PPA studies than NPA studies (W = 618, p = 0.5992). Mammals are the most-studied group (n = 108), followed by reptiles (n = 79), birds (n = 73) and amphibians (n = 58). Most of the studies took place in the Cerrado (54) and the Atlantic Forest (45), where are the greatest number of surveyed PAs, greatest number of PAs and greatest number of PAs without studies. Only 18 papers suggest specific mitigation measures for the study site. The increase in PPA studies is positive, but researchers need to increase contact with PA managers to produce scientific knowledge and develop more efficient mitigation measures for these areas. We encourage increased surveying of roads near PAs, involvement of researchers with environmental agencies, and more studies with small animals.

“…Roadways are part of contemporary landscapes and are necessary to interconnect places, facilitate transportation, and provide expansion and consolidation of the agricultural frontier [1,2]. However, roads are also indicators of anthropogenic pressure and habitat loss [3,4], which highlights the importance of studies that examine the environmental and economic benefits of roadside revegetation.…”

A trial was conducted to investigate the growth and production characteristics of four plant species, marking the initiation of research on roadside revegetation processes in the southern region of Piauí state, Brazil. The trial was conducted in greenhouse conditions to evaluate the response of the species—two native legumes (Arachis pintoi and Stylosanthes macrocephala) and two grasses (Brachiaria humidicula—non-native and Paspalum notatum—native)—under different fertilization and irrigation treatments. Data were collected in two harvest operations, measuring the following variables: total plant height, population density per pot, number of live leaves, plant moisture content, total forage biomass, and root biomass. The results suggested that fertilization and irrigation caused no significant effect on the major species development characteristics that allay with the highway agency interests. Arachis pintoi showed the best results with the lowest height (24.1 cm in Experiment 1 and 19.2 cm in Experiment 2) and the greatest total forage biomass yield (6.4 g plant−1 in Experiment 1 and 4.1 g plant−1 in Experiment 2). Thus, we recommend that the results found in this study should be extended to field experiments and long-term research. Because our study did not explore mixed-species designs, adopting such evaluation could offer advantages in achieving more comprehensive and resilient revegetation outcomes and help decision-making regarding target species to compose the roadside revegetation operations.
