Invasive Alien Species #IAS pose a major threat to 🇪🇺native plants and animals as they:
⚠️ are a major cause of biodiversity loss
📉 negatively impact the economy
🩺 affect human health

1/ 📢Yesterday saw the release of our analysis of the first @IUCNRedList global freshwater fauna assessment in @Nature ! The dataset took 1000+ experts 20+ years to compile. So what did we find? nature.com/articles/s41586-0…

Shedd Aquarium has partnered with the @IUCNssc to strengthen freshwater conservation, close the assessment gap for species like freshwater mussels, and make a difference for these critical organisms that support healthy ecosystems. sheddaquarium.org/care-and-c…

A new study co-authored by @IUCN reveals that 24% of freshwater species are at high risk of extinction. However, the extinction risk for many species, including molluscs, remains unknown due to insufficient data. iucn.org/press-release/20250…

New blog post about a new @Nature publication! The Global Freshwater Fauna Assessment shows that a quarter of freshwater animals are at risk of extinction. The Global Center's Freshwater Conservation Coordinator co-authored the publication. 🌍🧪🐟

Healthy wetlands are critical for climate mitigation, adaptation, biodiversity and human health. Protecting wetlands for our common future requires collaboration on policies, regulations and community initiatives that spur effective conservation.

@IUCNRedList
Topiltzin Contreras retweeted
A quarter of world's freshwater life at risk of extinction, reveals an @IUCN study.
The primary reason - loss of freshwater ecosystems across the world. Several factors: pollution, dams, climate change.
One overlooked factor, @LabRajeev days, is conservation efforts designed for iconic terrestrial species such as lion and tiger that pay no heed to the little guys.
Broader conservation strategies that incorporate freshwater species data is key.
