Extinction Threat for a Quarter of Freshwater Animals

According to a new study published in the journal Nature, nearly a quarter of the animals that live in rivers, lakes and other freshwater sources are at risk of extinction around the world.

The study is the first time researchers have analysed the global risk to freshwater species. Previous studies have focused on terrestrial animals, including mammals, birds and reptiles.

Researchers looked at around 23,500 species of dragonflies, fish, crabs and other animals that depend exclusively on freshwater ecosystems. They found that 24 per cent are threatened with extinction, classified as vulnerable, endangered or critically endangered, due to a combination of threats from pollution, dams, water extraction, agriculture, invasive species, climate change and other disturbances.

Unveiling the Mysteries of Cetaceans in the South China Sea: Chinese Scientists Describe Important Marine Mammal Areas (IMMAs)

Image
The world’s ocean ecosystems are facing mounting threats—climate change, marine pollution, overfishing, and habitat destruction due to human activities, to name a few. These pressures are particularly dangerous for marine mammals like cetaceans, whose survival hinges on healthy habitats and stable populations. Yet, in regions like the South China Sea, where biodiversity is exceptionally high, little research has been done to understand the needs and habitats of cetaceans. This lack of data has left a gap in our knowledge and made it challenging to establish targeted conservation strategies. Recognizing this, Chinese scientists have now set out to fill these gaps and contribute essential data to inform future policy and management, aiming to protect these vulnerable species and support the objectives of the Kunming-Montreal Global Biodiversity Framework (GBF). In a landmark study published on October 8, 2024, in Biological Conservation, Dr. Li Songhai and his team from the Institute of...
