Uso do pó fluorescente no estudo de rastreamento de serpentes na Floresta Atlántica, Nordeste, Brasil.

There are few studies on snake tracking and this number is even lower when it comes to the Atlantic Rain Forest in Brazil. There are relatively few methodologies for carrying out these studies and most researchers use radio telemetry when possible. In this work we use the fluorescent powder in snakes, glimpsing studies on displacement, occupation and area of, as well as comparing the technique in terms of positive and negative points with other methods. 16 individuals of nine species were monitored in captures that took place bimonthly between 2016 and 2017, in an urban fragment of Atlantic rain forest in the Parque Estadual Dois Irmâos in northeastern Brazil. The tracking resulted in an area covered up to 23 m, in which terrestrial species had their tracks more easily identified, as was the case of Xenodon rabdocephalus. The humidity of the air, the heterogeneity of the forested environment seems to be the main obstacles to the loss of trails. The fluorescent powder is an affordable not invasive method that provides details of displacement, however is limited in terms of durability of the traces. [ABSTRACT FROM AUTHOR]
