“…In Brazil, where the network of paved and unpaved roads extends over 1,725,000km (GEIPOT 2000), research on road ecology as a conservation effort is new. The few studies addressed mortality from roadkills only (Novelli et al 1988;Vieira 1996;Fischer 1997;Prada 2004;Pereira et al 2006;Cheren et al 2006).…”

Roadkills of vertebrate species on two highways through the Atlantic Forest Biosphere Reserve, southern Brazil

We assessed the magnitude, composition, and spatial and temporal patterns of road mortality of native vertebrates on two highways in southern Brazil from 18 January 2003 to 26 January 2004. The highways cross remnants of the Atlantic Rainforest, a global biodiversity hotspot, and differ in vehicle traffic and surrounding landscape. We compared the road-kill magnitude and composition of birds, mammals, and reptiles between roads and seasons. We used a modified K statistic to depict the spatial patterns of roadkills of these groups and tested the association between vehicle traffic and road mortality through linear regression. We recorded 869 kills of 92 species. The two roads differed regarding the abundance and composition of roadkills. Reptile road mortality was higher in summer than winter, but all other groups did not show significant difference in the magnitude of mortality between seasons. The composition of killed assemblages differed significantly for some of the taxonomic groups among seasons. We found only one positive association between roadkills and vehicle traffic (reptiles on one of the roads), suggesting that vehicle flow does not explain the road-kill temporal variation on these roads. Total vertebrate, bird, and mammal roadkills showed significant spatial aggregations possibly due to variation in vehicle traffic, highway design, and local landscape condition and arrangement. With expected expansion of the road network, mitigation measures for multi-species assemblages should include habitat protection, soil use regulation, road crossing structures, speed reducers, and campaigns to raise people's awareness about road impacts on wildlife.

“…First geographic records (FGR) and new roadkill records (NRR) for reptile and bird species were verified from the literature. We compared our dataset to data collected by De Souza et al (2014) from the same highway (BR-262) and data of road-killed reptiles and birds from other Brazilian roads (Novelli et al 1988, Prado et al 2006, Silva et al 2007, Coelho et al 2008, Hengemühle and Cademartori 2008, Cunha et al 2010, Hartmann et al 2011, Ramos et al 2011, Santana 2012, Santos et al 2012, 2014Carvalho et al 2014, Klippel et al 2015, Machado et al 2015, Almeida et al 2016, Braz and França 2016, Deffaci et al 2016, Saranholi et al 2016, Steil et al 2016, Corrêa et al 2017, Miranda et al 2017, Rodríguez-Castro et al 2017, Viturino and Graciolli 2017, Gonçalves et al 2018, Ramos-Abrantes et al 2018.…”

We monitored reptile and bird roadkills in Cerrado–Pantanal landscapes along the Campo Grande to Corumbá highway BR-262. We describe species distribution in different landscape zones, including the first geographic record for Hydrodynastes bicinctus Herrmann, 1804 in the Pantanal basin. The roadkill occurrence of Spizaetus melanoleucus (Vieillot, 1816) is an outstanding record. We recorded 930 individuals belonging to 29 reptile and 47 bird species; 20 of these species are new roadkill records in Brazil. The 8 new records of reptile species include Eunectes notaeus Cope, 1862, Bothrops mattogrossensis Amaral,1925, Dracaena paraguayensis Amaral,1950 and H. bicinctus; and 12 new records of bird species include S. melanoleucus, Heterospizias meridionalis Latham, 1790, Urubitinga urubitinga (Gmelin, 1788), Pulsatrix perspicillata (Latham, 1790), Aramus guarauna (Linnaeus, 1766), and Jabiru mycteria (Lichtenstein, 1819). Richness of road-killed species on the BR-262 highway seemed to be high, reinforcing concerns about wildlife-vehicle collisions where these accidents occur, as they lead to long term and chronic impacts on wildlife and road safety in the Pantanal region.

“…Some have sought to identify roadkill hotspots, but these analyses were based solely on roadkill rates. Pereira et al (2006) and Novelli et al (1988) studied the distribution of roadkills on each kilometer of highway, whereas Prado et al (2006) and Gumier-Costa & Sperber (2009) divided the highways into stretches of five kilometers or more. Coelho et al (2008) tested the spatial distribution of roadkills, seeking to identify aggregations, without a priori determining the length of the road stretches.…”

. Priority ranking of road sites for mitigating wildlife roadkill. Biota Neotrop. 10(4): http://www.biotaneotropica.org.br/v10n4/en/abstract?article+bn03010042010. Abstract:We propose a ranking index to assign priorities to sites for implementation of measures to mitigate wildlife roadkill. We conducted a case study along 34 km of highway BR 392 in Southern Brazil. We compared priority sites established only according to roadkill rates, with those defined by our index. The index used four parameters: the richness of target species, diversity of roadkilled species, roadkill rate of target species, and presence of endangered species. Although it is impossible to protect the entire community of vertebrates affected by roadkill, we defined nine target species, five mammals and four reptiles. For each parameter, we defined coefficients ranging between 0 and 3. There was a significant change in the priorities of sites for implementing mitigation devices, which caused changes in the species that were protected. The definition of priority sites by considering only the roadkill rate protected reptiles especially, to the detriment of all mammal species, including endangered species. Sites with high roadkill rates continued to be among the most important for conservation, but the index diluted the effect of this parameter, changing the ranking. This ranking index can be an effective tool to aid government institutions in decision-making, especially when more elaborate analyses are not feasible for reasons of time, resources, or lack of trained personnel.
