“…Three invasive—the African house gecko, Hemidactylus mabouia (Moreau De Jonnès, 1818), the rodent Mus musculus (Schwartz & Schwartz, 1943), and the American bullfrog, Rana catesbeiana (Shaw, 1802) are abundant and have well‐established populations in Brazil (Adelino & Lima, 2023; Santos‐Pereira & Rocha, 2015; Vanzolini, 1978). These species have caused significant negative impacts on local biodiversity (Adelino & Lima, 2023, Santos‐Pereira & Rocha, 2015).…”

“…Among several countries in the world, Brazil is a territory prone to and vulnerable to biological invasions due to its vast area, extensive coastline, and climatic conditions conducive to the establishment and persistence of invasive species (Adelino & Lima, 2023). This vast region of South America with high native biodiversity harbors more than 37 invasive vertebrate species (Adelino & Lima, 2023). Three invasive-the African house gecko, Hemidactylus mabouia (Moreau De Jonnès, 1818), the rodent Mus musculus (Schwartz & Schwartz, 1943), and the American bullfrog, Rana catesbeiana (Shaw, 1802) are abundant and have well-established populations in Brazil (Adelino & Lima, 2023;Santos-Pereira & Rocha, 2015;Vanzolini, 1978).These species have caused significant negative impacts on local biodiversity (Adelino & Lima, 2023, Santos-Pereira & Rocha, 2015.…”

The presence of invasive species in the environment can be highly detrimental. The success of these species depends on their interaction with native ones. The prey–predator relationship between invasive and native species can result in biodiversity loss or the introduction of new food items for local predators. Due to its tropical and extensive nature, Brazil is vulnerable to the colonization of invasive species. Snakes are a group of animals that can act as both predators and prey for invasive species. The pitviper Bothrops jararaca is an abundant and widely distributed native species on the Brazilian coast. Based on this, we conducted a study on the feeding preferences of naive B. jararaca juveniles regarding invasive and native prey. We found that this species exhibits a greater preference for native anurans compared to Rana catesbeiana, an invasive amphibian associated with significant environmental impacts. Additionally, the gecko Hemidactylus mabouia, a prey that triggered intense predatory responses from the pitviper, reveals that this species, even with a short period of coexistence with B. jararaca, has established an intense prey–predator relationship. The negative correlation between prey size and feeding interest, guided solely by olfactory cues, adds a layer of complexity to understanding the feeding choices of B. jararaca, providing valuable insights for conservation and environmental management strategies.Abstract in Portuguese is available with online material.
