“…A selection of stretches for the implementation of roadkill mitigation measures should be made with caution, so that important areas are not eliminated during the selection process (BAGER et al, 2010). The adequate location of wildlife crossings, for example, can improve or maintain connectivity between animal populations (LESBARRÈRES; FAHRIG, 2012; VAN DER GRIFT et al, 2013).…”

ABSTRACT:Researches on roadkill aggregations are important tools for wildlife conservation. The objective of this study was to determine wild vertebrate roadkill aggregations on a stretch of 96 kilometers of the BR-050 highway, between the cities of Uberlândia and Uberaba, State of Minas Gerais, Brazil. The survey was conducted between April 2012 and March 2013. Roadkill monitoring was performed by car, at a speed of approximately 60 km/h, and forty two (42) weekly trips, totaling 8064 km, were performed. The 2D Ripley's K-Statistics test from the Siriema v1.1 program was used to detect the scales of roadkill aggregations and 2D HotSpot Identification test was used to identify the location of these hotspots. Aggregations extended from the following kms: 14 to 33, 38, 41 to 51, 66 to 70 and 78 to 94. We found roadkill aggregations for wild vertebrates and mammals. The roadkill aggregations were significant for Euphractus sexcinctus, Conepatus semistriatus, Procyon cancrivorus, Hydrochoerus hydrochoerus, Cariama cristata, Boa constrictor amarali and Crotalus durissus collilineatus according to the taxonomic specific level. Thus, it is suggested that mitigation measures for vertebrate conservation must be implemented in the indicated areas.

“…Uno de los aspectos más investigados en relación a la "ecología de la carretera" es el atropellamiento de vertebrados silvestres (Coffin, 2007). Esos estudios han sido realizados principalmente en Norteamérica y Europa (Madsen, Strandgaard & Prang, 2002;Pokorny, 2006;Grilo, Bissonette & Santos-Reis, 2009), aunque en los últimos años se ha incrementado el interés sobre este tema en los países del Neotrópico, particularmente en Brasil (Delgado, 2007;Coelho, Kindel, & Coelho, 2008;Turci & Bernarde, 2009;Gumier-Costa & Sperper, 2009;Bager & Rosa, 2010; Vargas-Salinas, Delgado-Ospina & López-Aranda, 2011;Quintero-Ángel et al, 2012). En el caso de Venezuela sólo se conocen tres trabajos publicados en revistas arbitradas (Ramo & Busto, 1986;Rodda, 1989;Pinowski, 2005).…”

Vertebrate mortality in the Guanare-Guanarito road, Portuguesa state, Venezuela. Roads directly or indirectly affect the structure, dynamics and function of ecosystems that they traverse. Most studies on the effect of roads on wildlife focus on the evaluation of mortality of vertebrates by vehicle collisions. Despite the extensive road network that exists in Venezuela, studies of wildlife mortality in them are scarce. In this paper, we analyzed the temporal and spatial pattern of vertebrate's collisions along the road Guanare-Guanarito, in Portuguesa state. We travelled 26 times between these towns (74km) to localize dead vertebrates, at a speed of 50-60km/h. of those trips were conducted from ; these ones, with the aim to include months and seasons that were insufficiently sampled during the first period. The elapsed time between trips varied from 14 to 37 days. The total distance traveled was 1 924km. Dead animals found amounted 464 individuals, 66 of them were birds (25 identified species), 130 mammals (15 species) and 268 reptiles (18 species). The species with the highest number of individuals were the snake Leptodeira annulata (n=119), the oppossum Didelphis marsupialis (n=39) and the spectacled caiman Caiman crocodilus (n=33). Excluding domestic animals, the rate of road-killed vertebrates was 0.2282indiv./km, a figure 28.3% higher than previous studies in the same road. Changes in the relative number of collisions for some species, respect to the numbers reported 20 years ago, were linked to the increase in traffic flow and changes in land use. Road segments with collision rates higher than expected by chance were identified. Collition by cars may be the principal cause of mortality for species like the tamandua (Tamandua tetradactyla) and the giant anteater (Myrmecophaga tridactyla), the last considered a vulnerable species. Some basic measures are proposed to reduce wildlife mortality on the road. Rev. Biol. Trop. 61 (4): 1619-1636. Epub 2013 December 01.

ABSTRACT. Several factors, such as hunting and the pet trade, are responsible for the worldwide decline of wildlife populations. In addition, fatal collisions with vehicles on highways have also taken one of the largest tolls. This study aimed to quantify the richness and abundance of vertebrate roadkill along highway MS-080 in Mato Grosso do Sul, Central-West Brazil. We compare the amount of roadkill to the distance between cities, moon phases and the flow of vehicles on the highway. Samples were collected weekly between March and September 2011, totaling 257 individuals, belonging to 32 families and 52 species, resulting in an index of 0.13 individuals hit/km. Birds were the most frequently hit taxa, followed by mammals. The most affected species was Cariama cristata (Cariamidae), followed by Cerdocyon thous (Canidae). The sections of highway closest to cities had the highest number of individual animals killed. Our observations indicate that the density of the vegetation next to the highway positively influences the amount of roadkill.KEYWORDS. Conservation, roads, roadkill, urbanization, habitat fragmentation.RESUMO. Velozes e furiosos: um olhar sobre a morte de animais na rodovia MS-080, centro-oeste do Brasil. Vários fatores são responsáveis pelo declínio da fauna mundial tais como a caça e comércio de animais selvagens. Mas a maior delas tem sido o atropelamento por veículos em rodovias. Este estudo teve como objetivo quantificar a riqueza e abundância de vertebrados atropelados ao longo da rodovia MS-080, em Mato Grosso do Sul, na região Centro-Oeste do Brasil. Além disso, nós relacionamos a quantidade de atropelamentos à distância entre as cidades, as fases da lua e o fluxo de veículos na rodovia. As amostras foram coletadas semanalmente, entre março e setembro de 2011, totalizando 257 animais atropelados, pertencentes a 32 famílias e 52 espécies, resultando em um índice de 0,13 indivíduos atropelados/km. As aves foram as mais frequentemente atropeladas, seguidas pelos mamíferos. As espécies mais afetadas foram Cariama cristata (Cariamidae) e Cerdocyon thous (Canidae). As seções da rodovia mais próximas das cidades apresentaram um maior número de animais mortos. As nossas observações indicam que a densidade da vegetação ao lado da estrada influencia positivamente na quantidade de animais mortos na estrada. PALAVRAS-CHAVE.Conservação, rodovias, atropelamentos de fauna, urbanização, fragmentação de habitat.
