While the threat of climate change increases, biodiversity is also being affected by another problem, the introduction of non-native species that are resistant to environmental disturbances. Some of these non-native species can become invasive and have negative impacts on native ecosystems, public health, and the economy. In this context, society, government, and the academic community—each according to its role—must manage such species, which is a process involving prevention, detection, and control. In this video, the researchers who compose eMIAS (South American Invasive Mollusks Specialists) focus on compiling a reference work for the 29 mollusc species that are native to South America and that have been introduced to other continents. Among those 29 species, 10 are marine, 10 are freshwater, and 9 are terrestrial. These introductions, over the past five decades, have been facilitated by an increase in global trade as well as in environmental degradation in many areas (e.g., climate change, urbanization).
