Non-marine invasive gastropods on Ilha Grande (Angra dos Reis, Rio de Janeiro, Brazil): distribution and implications for conservation

A new inventory of non-marine invasive gastropods on Ilha Grande, Brazil, reveals three species—Melanoides tuberculata, Physa acuta, and Achatina fulica—with the latter being the most widespread, found in 16 villages. Most records were concentrated in anthropogenic areas, likely due to accessibility, but one was documented within a conservation area, raising concerns about potential ecological impacts. The study highlights the need for targeted conservation efforts to mitigate the spread of these invasive species, which pose significant threats to local biodiversity.
