Over the past 15 years, Brazil has seen a more than 200% increase in non-native mollusk species
A study published in the journal Biological Invasions indicates that Brazil currently has at least 82 non-native mollusk species, in addition to 13 whose origin cannot be determined. This represents a

The surge in non-native mollusk species in Brazil isn’t just an ecological footnote—it reflects how globalization’s unintended consequences are reshaping ecosystems faster than science can keep pace. While invasive species often fly under the radar, their unchecked spread can disrupt agriculture, freshwater systems, and even human health, signaling broader environmental vulnerabilities that could ripple across South America.
Background Context
Brazil’s biodiversity is already a global hotspot, but the country’s role as a major agricultural exporter has made it a magnet for stowaway species hitchhiking on global trade routes. Decades of infrastructure expansion—from ports to hydroelectric dams—have inadvertently created corridors for these invaders, while climate change may be lowering natural barriers that once contained them.
What Happens Next
Without aggressive biosecurity measures, Brazil could face a tipping point where certain regions become overrun by mollusks that outcompete native species or transmit parasites to livestock and humans. Regulators may soon face pressure to adopt stricter import controls or invest in early detection tech, but the window for prevention is closing as trade volumes continue to rise.
Bigger Picture
This trend mirrors a planet-wide pattern: as trade volumes tripled over the past 30 years, so did the number of invasive species, turning biodiversity loss into a silent crisis. Brazil’s case underscores how emerging economies, often balancing development with conservation, are now on the front lines of an ecological reshuffle that demands urgent, globally coordinated responses.
