Levantamento de aves atropeladas nas estradas Emade e Agrovila no Município de Tefé (AM) em comparação a outros estudos de ecologia das estradas no Brasil

Abstract

Roads have been identified as one of the main anthropogenic causes, negatively affecting biodiversity and biotic integrity. Vehicle collisions have been one of the most evident environmental impacts generated by roads on wildlife, causing damage to a wide diversity of vertebrate species in different biomes. In fact, highways can affect the surrounding area and alter patterns of bird diversity and abundance, resulting from differences in tolerance in response to the disturbance caused to each species. In this way, the impacts caused by highways are specific to different species of birds, showing the importance of investigating their occurrences to determine measures to mitigate these impacts. The birds that were listed in his work do not have identical distributions, including species that are endemic to the state of Amazonas, leading us to believe that the occurrence of these species is not restricted to the state. In a way, of the 1971 species of birds that occur in Brazil in Tefé, in Amazonas, there are 342 species of birds. In tropical regions, interest in the subject has been recent, resulting in a lack of understanding of the patterns and effects of vertebrate collisions. Since to preserve it it is necessary to have knowledge about the distribution of biodiversity, as it allows us to recognize areas with vulnerable organisms and thus direct mitigating measures. The extension of the Amazon road network density is still small and with low vehicle circulation compared to other regions of the country. This may be associated with the smaller number of published studies on road-killed fauna, but it is worth noting that the roads present are generally associated with extensive green areas, one of the factors that make these highways different from others, especially in the context of landscape. wide distribution and that feeds mainly on seeds of grasses such as brachiaria, and also captures insects, foods that are present around roads, factors that influence it being run over on other roads in Brazil. In particular, the state of Pará, which presented three studies with the highest numbers of bird species run over, similar to the bird species on the Agrovila and Emade roads.
