“…This coincided with the highest intensity of motor traffic, and consequently with the highest snake death on the roads. Thus, the rate of snake roadkills was not related to the breeding period (BERNARDINO & DALRYMPLE 1992).…”

“…In the rainy season, especially after a tropical shower, the temperature drops, and this may motivate snakes to lie on warm asphalt. This behaviour is known in many regions of the world (BERNARDINO & DALRYMPLE 1992). The highway mortality of snakes in the Sonora Desert of South Arizona, USA, is high during the monsoon-like rainy season, from July to early September.…”

“…Their number increases in the rainy season (CORDERO 2000), that is, during the period of our study. In addition to their normal activity, they may be attracted to roads by the carcasses of killed animals (BERNARDINO & DALRYMPLE 1992, CORDERO 2000. Among mammals, opossums were the most frequent roadkills (Tab.…”

Revista Brasileira de Zoologia 22 (1) : 191-196, março 2005 Vertebrate roadkills were observed during the rainy season (June-October) during five passages along the 572 km road between Caracas and Mantecal/Apure in Venezuela, a total distance of 2860 km. Five dominant landscape types were identified along this road: 1) the Coastal Cordillera area, which includes crop fields, woods, dry savannah, and settlements; 2) non-flooded llanos with clumps of trees and palms and small bodies of water; 3) artificially watered rice plantations; 4) gallery forest along the river Apure, with a few crop fields; and 5) flooded llanos, largely drained, with many embankments and storage reservoirs. The gallery forest yielded 30 carcasses, the largest number. The greatest number of carcasses were noted in October, at the end of the rainy season.Since data on animals killed on roads by passing vehicles began to be published long ago (STONER 1925, 1935, KNOBLOCH 1939, SPRAGUE 1939, DICKERSON 1939 RESUMO.

Este trabalho apresenta uma análise de vertebrados mortos em estrada em cinco habitats tropicais diferentes na América do Sul. As observações dos vertebrados mortos em estrada foram feitas em 1978, a 572 km da rodovia entre Caracas e Mantecal/Apure na Venezuela, durante a estação das chuvas (junho-outubro). Durante cinco passagens nesta rota, a qual inclui cinco habitats diferentes, foram encontradas 79 carcaças de vertebrados -répteis e mamíferos. Assumindo que as carcaças permaneçam por dois dias na estrada, é esperado que veículos matem 350 crocodilos Caiman crocodilus Linnaeus, 1758 (Alligatoridae), durante a estação das chuvas. Cálculos similares foram feitos para outras 313 espécies de cobras e lagartos, 294 gambás Didelphis marsupialis Linnaeus, 1758 (Didelphidae), 220 raposas Cerdocyon thous (Linnaeus, 1776) (Canidae), 129 tamanduás Tamanduá tetradactyla (Linnaeus, 1766) (Myrmecophagidae), 55 capivaras Hydrochaerus hydrochaeris (Linnaeus, 1766) (Hydrochaeridae) e 37 lebres Sylvilagus floridanus Allen, 1890 (Leporidae). Numerosos trabalhos têm sido publicados sobre vertebrados mortos por veículos em estradas da Europa, Amé-rica do Norte e Austrália e vários trabalhos têm sido referências úteis sobre vertebrados mortos em estradas na África e Ásia. Da América do Sul existem vários trabalhos com vertebrados, pássaros e mamíferos, sendo que da Venezuela existe apenas um que tenha tratado de iguanas (Iguana iguana Linnaeus, 1758, Iguanidae).

“…Snakes are the reptiles that are most likely to be hit on roads, due to their characteristic long body morphology and their habit of frequently using roads as thermoregulation sites (Bernardino & Dalrymple 1992, Bonnet et al 1999. Most reptiles found on CVPN roads were snakes or long-bodied lizards, such as Ophiodes aff.…”

Chapada dos Veadeiros National Park is one of the most important protected areas of the Brazilian Cerrado and is inhabited by diverse species, but the area has seldom been studied. From 2006 to 2008, we studied the impact of roads on wild vertebrates by recording roadkill on the two main roads located in the vicinity of the park. Of 824 killed vertebrates belonging to 138 species that were recorded, the species that were found most often in each vertebrate group were the Schneider's toad (Rhinella schneideri), the grassland sparrow (Ammodramus humeralis), the yellow-toothed cavy (Galea flavidens), and the marbled lancehead (Bothrops marmoratus). The roadkill rate was 0.096 animals km -1. Vertebrate mortality was significantly higher during the wet season. There is a significant relationship between habitat structure and the vertebrates that were found as roadkill: amphibians are associated with nearby forest and paved roads, birds with nearby pastures, reptiles with nearby grassland, and mammals with unpaved roads. Action should be taken such as highway fencing in combination with safe crossing opportunities for wildlife in order to decrease the number of animals killed on the roads. Keywords: road ecology, protected areas, conservation, cerrado. , o tico-tico-do-campo (Ammodramus humeralis), o preá (Galea flavidens) e a jararaca (Bothrops marmoratus). A taxa de atropelamento foi de 0.096 animais km -1 , com uma mortalidade significativamente maior durante a estac¸ã o chuvosa. Foi encontrada uma relac¸ã o significativa entre a estrutura do habitat e as classes de vertebrados atropelados nas rodovias, sendo o grupo dos anfíbios associados a fragmentos florestais e trechos pavimentadas das rodovias, o das aves associado com pastagens circundantes, répteis com campos e mamíferos com trechos nã o pavimentados das rodovias. Medidas como barreiras que impec¸am a movimentac¸ã o dos animais nas estradas, bem como passagens seguras sã o indicadas para a reduc¸ã o do nú mero de animais mortos nas rodovias na regiã o do Parque. Palavras-chave: ecologia de estradas, áreas protegidas, conservac¸ão, cerrado.

“…Este tegumento não é isolante e sua termorregulação é realizada procurando ativamente temperaturas ambientais adequadas, expondo, por exemplo, sua pele ao sol ou em contato com superfícies quentes ou frias o que os faz extremamente dependentes do ambiente (STORER et al 2003;POUGH et al 2008). Possivelmente, em função disso, as serpentes são frequentemente atraídas pelo calor do asfalto para realizarem a termorregulação e, consequentemente, são atropeladas (BERNARDINO et al 1992;PINOWSKI, 2005).

Anfíbios & "répteis" atropelados em um trecho da Palavras-chave: Herpetofauna; Serpente; Rodovia; Impacto Ambiental. Amphibians & "reptiles" bowled over on a stretch of the BR-232, state of PernambucoAnimals run over on roads and highways have been drawing attention of researchers to investigate the actual impact of the loss of these animals to the environment. The roads are among the environmental changes that caused the most impacts on natural landscapes, with physical, chemical, biological and ecological effects. The present study aimed to list the amphibians and reptiles trampled on the BR-232 highway, the stretch between the towns of Sierra Fishing Hewn. The route was traveled during the years 2009-2011, on average vehicle speed between 40 and 60 km / hour. Animals sighted were photographed and identified when possible. Of the 13 stations and a total of 89 individuals distributed among 24 species of amphibians (n = 2) and reptiles (n = 22) were recorded during this period. Species with highest registration numbers were the anuran amphibian Rhinella jimi (n = 14), and snakes Boiruna sertaneja (n = 14) and Boa constrictor (n = 12). The stretches between the towns of Fishing-Arcoverde and Custody-Carved Sierra were those who had a greater number of occurrences, possibly due to the area of Caatinga scrub and trees found along this route. This work highlights the need for environmental mitigation actions in this passage, aimed at reducing the number of pedestrian accidents.
