Approaches to capturing the Black and White Tegu Salvator merianae (Squamata: Teiidae)


Zoologia (Curitiba)




ABSTRACT The use of traps is extremely important in several types of ecological studies, and may assist in the capture of individuals in areas that are difficult to access. In the present study, we compared the effectiveness of wooden (Schramm) versus "Tomahawk" traps to capture Salvator merianae (Duméril & Bibron, 1839) lizards. The study was conducted in Eldorado do Sul, Rio Grande do Sul, Brazil. Field data were collected from August 2013 to March 2015, during the reproductive period of the species. The study involved two types of baited traps: i) "Tomahawk", made of galvanized steel; and ii) Schramm, a wooden trap. The capture rate of the Schramm wooden traps was 1.63 individuals/day, and of the "Tomahawk" was 0.36 individuals/day. These results are important for researchers working with large lizards and may help to increase sampling efficiency for these organisms.
