“…La periodicidad de atropellos a lo largo del año está asociada a la fenología de las especies, la cual está a su vez determinada principalmente por los cambios en el régimen lluvioso en el transcurso del año (Rodda, 1989;Ashley & Robinson, 1996;Clevenger et al, 2003;Gumier-Costa & Sperber, 2009;Lagos, Picos, & Valero, 2012). Los picos observados en el presente estudio se explican porque algunas especies, como por ejemplo C. crocodilus, aumentan su movilidad al inicio de las lluvias (abril) o al comienzo de la época seca (noviembre) (Ramo & Busto, 1986).…”

“…Otra especie que mostró una tasa de mortalidad preocupante fue T. tetradactyla. Individuos del género Tamandua aparecen de manera destacada en los estudios de fauna atropellada en el Neotrópico (Monge-Nájera, 1996;Fischer et al 2004;Pinowski, 2005;Pereira, Andrade & Fernandes, 2006;Melo & Santos-Fihlo, 2007;Gumier-Costa & Sperber, 2009;Cunha et al, 2010). Es muy probable que los atropellos sean la principal causa de mortalidad para T. tetradactyla en Venezuela.…”

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.

“…In the Amazon, one individual was recorded on the PA‐275 highway, in Carajás National Forest (Table S1). While there are no vehicle collision with giant armadillos recorded in literature on this highway, other animals were frequently recorded (Gumier‐Costa & Sperber, 2009). In the Atlantic Forest, there is currently no record for roadkill of giant armadillos, although many other species are victims of vehicle collisions in the SBR and VNR (Klippel et al, 2015), including large mammals (Srbek‐Araujo, Mendes, & Chiarello, 2015).…”

Highways are a threat for giant armadillos that underpasses can mitigate

We report 22 records of giant armadillo roadkill on Brazilian highways in the Cerrado, Pantanal and Amazon biomes illustrating that highways are a threat to this species.However, we also documented the species using underpasses, demonstrating that these structures could help to reduce the risk of roadkill for giant armadillos.

“…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.
