“…The number of roadkilled individuals did not differ between seasons, which may be a consequence of resource scarcity during all seasons, leading animals to travel large distances year round (Prado et al 2006). Such results corroborate the study conducted by Orlandin et al (2015), and are in disagreement with the results found by Prado et al (2006) and Cáceres et al (2012), which observed influence of seasonality on roadkill frequencies. The occurrence of roadkill events of medium and large-sized mammals in the dry season seems to be associated with resource scarcity, which is a condition that implies higher needs of animal locomotion.…”

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 lack of significant seasonality in the roadkill records for BR 364 and other roadways (Pereira et al, 2006;Cunha et al, 2010;Costa & Dias, 2013;Silva et al, 2013;Orlandin et al, 2015) may reflect the tendency toward a predominance of species with a high capacity for adaption to varied environments. Thus, the dry and rainy seasons offer distinct resources that can be exploited by species with opportunistic generalist habits, as those occurring along BR 364.…”

Roadways and road traffic modify landscapes, posing a threat to the conservation of species in different biomes. The aim of the present study was to analyze roadkill records of wild mammals and to compare the results to findings from 37 other studies conducted in Brazil, to evaluate the richness and diversity of threatened species in different eco-regions of the country. This study was conducted between June 2007 and June 2008, along 60 km of the inter-state highway BR-364, which connects the municipalities of Ouro Preto d’Oeste and Presidente Médici in the state of Rondônia (northern Brazil). Two hundred twenty roadkills were recorded involving 13 species of mammals. Cingualata, Pilosa and Carnivora were the most represented orders. The most represented were the generalist species Dasypus novemcinctus (56.7%), Tamandua tetradactyla (10.5%), and Cerdocyon thous (8.2%), reflecting the adaptability of these species to habitat changes and presence of humans. The number of roadkilled individuals and species indicated no significant differences between the dry and rainy seasons. The findings indicate a high index of roadkills (3.38 individuals/km/year) and moderate number of run over species (0.20 species/km/year) in the region in comparison to records from other roadways in Brazil, with 46% species having an endangered status. Roadways in the eco-regions of the Cerrado (Brazilian savanna) accounted a significantly larger proportion of endangered species (mean: 52%) in comparison to the Pampa (lowlands of southern Brazil; 24%), but the differences in comparison to roadways in Amazonia (37%) and the Atlantic Forest (31%) were non-significant. The present findings underscore the need for emergency measures to minimize the impact of roadkills on mammals. Moreover, priority should be given to more impacted roadways and more threaten eco-regions.

“…Os mamíferos com maiores valores de frequência de ocorrência foram Cerdocyon thous e Procyon cancrivorus, que também foram as espécies mais frequentes no nível estadual, em registros de atropelamentos (CHEREM et al, 2007). Além disso, Cerdocyon thous também é em geral a espécie com maior número de registros em estudos realizados na região oeste de Santa Catarina ( ONGHERO-JR. et al, 2012;ORLANDIN et al, 2015).…”

Bacias hidrográficas como unidades de variação geográfica e de conservação de vertebrados

É fato que os vertebrados sofrem variação em sua distribuição de acordo com vários fatores, tais como uso da terra e altitude. Esses animais podem apresentar diferenças em sua composição no mesmo bioma, dentro de certa unidade geográfica, e.g. no estado de um país. Esta pesquisa analisou a composição de diferentes espécies de vertebrados na bacia hidrográfica do Rio do Peixe, no sul do Brasil. Verificou-se que todos os grupos de fauna, com exceção de peixes e anfíbios, sofreram variação geográfica significante ao longo de três regiões específicas da área de estudo. Tais resultados mostram que as bacias hidrográficas provavelmente funcionam como unidades de variação geográfica de vertebrados neotropicais. Dessa maneira, deve haver políticas de conservação para as diferentes áreas de uma bacia hidrográfica, o que contribui para a manutenção das espécies de vertebrados.
