Ficha catalográfica da biblioteca 3 4 5 6 7 8 9 10 AGRADECIMENTOS Agradeço aos meus pais Cristiane e Roberto, pela oportunidade de estudar e à minha tia Elza e avós Anna, Elias, Circe e Takeshi, pelo incentivo que sempre recebi. Aos muitos mestres que tive ao longo da vida que entalharam os degraus que subi, em especial na UEL, no INPA, na UFG, no Butantan e na USP, onde me sinto em casa, mas também no mundo e no mato, onde sempre aprendi. Aos amigos antigos e novos que me proporcionam paz ocasional, relativa sanidade e alguma vontade de seguir caminhando. Ao pessoal de Noronha que foram importantes em todas as etapas deste trabalho e que fazem parte desta luta, alguns na ilha, outros espalhados pelo mundo. Aos amigos que deixei do outro lado do mundo, mas que continuam por perto e com quem podem contar. Aos amigos do RAN e do ICMBio que sempre me apoiaram, toleraram e as vezes até me escutaram. Continuem tendo paciência. Ao meu caríssimo orientador, aos amigos, colegas e professores da família VPS, obrigado pela acolhida e pela confiança. Obrigado: ABSTRACT ABRAHÃO, C. R. Strategies for the management of the tegu (Salvator merianae Duméril & Bibron, 1839), an invasive lizard in the archipelago of Fernando de Noronha, PE, Brazil. 2019. 124 p. Tese (Doutorado em Ciências) -Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, São Paulo, 2019. Fernando de Noronha is an oceanic archipelago placed 345 km off the Brazilian coast and inhabited since the 17th century. Its tourism-based economy is increasingly growing in the last decades. This unique ecosystem is recognized by Unesco as a World Heritage site and is also a Ramsar site. The whole terrestrial extension and a large marine area around the archipelago are protected by two federal protected areas, supervised by the Instituto Chico Mendes para Conservação da Biodiversidade. There are at least 15 species of native plants and animals officially endangered, some of them endemic to the archipelago. Among the 22 invasive species of plants and animals known to Fernando de Noronha, the tegu lizard (Salvator merianae)constitutes a great risk to native fauna as a large opportunistic predator. The potential impact of the tegu is recognized, and its management is predicted to the protected areas of the archipelago.This species achieves high densities on the main island and there is evidence of its presence at least on Rata Island. Densities found for FN were 13.8 ± 3.9 animals per hectare in an uninhabited area of preserved vegetation and 4.0 ± 1.1 animals per hectare in a sparsely populated area. Total numbers of animals for the main island ranges from 6,906 to 12,270 adults. The home range is 10.54 (7.3-15.3) hectares for both sexes. Capture probability is 0.24 ± 0.06 animals/trap/day in the area with 4.0 animals/ha, being influenced by the size of the individuals. The tegu also represents a potential public health risk for the archipelago, as carriers of the bacteria Salmonella enterica, isolated from 56.9% of the captured animals and found in 70.5% ...

The economic costs of biological invasions in Brazil: a first assessment

“…Invasive in the Fernando de Noronha archipelago the species is considered a threat to the native community species by hosting, transporting, and spreading parasites to new regions (Ramalho et al 2009). Further, effective management of the species is a challenge which incurs in economic costs associated with conservation plans design and in its absence the species can harm the livelihood of the local population by spreading zoonotic diseases (Abrahão 2019).…”
