PhD project by Marcos Ferreira Vila Nova

Bothrops jararacussu is the largest species within the genus Bothrops and one of which has the venom more toxic to humans. Its distribution covers Argentina, Bolivia, Paraguay and four Brazilian states: Rio Grande do Sul, Minas Gerais and Bahia. According to Official List of Fauna Species Endangered by the State of Bahia, Brazil, this species is endangered. For this species, little information is known about activity, environment use, feeding ecology and standard displacement under natural conditions. This is the first study conducted with populations in the state of Bahia, the most northerly geographical limit ever known, where nothing is known about the ecology of the species. The general objective of this research is to describe aspects of the ecology of Bothrops jararacussu from populations close to the Boa Nova National Park, the only known conservation unit in the Planalto Sul-Bahiano, using telemetry through subcultaneous implantation of a radio transmitter. After these procedures, the snakes will be released at random points in the Park and monitored.
