Boom! Detecting Gregarious Goliath Groupers Using Their Low-Frequency Pulse Sounds

From growls to booms, whales, fish and crustaceans all produce sounds. Selecting the gregarious Goliath grouper, researchers deployed a novel automated detector and localization model to find underwater marine organisms using their low-frequency ...

Dolphin Ages, Pod Health Revealed With Drone Photographs

Using unoccupied aerial system, or drone, photographs, researchers are now able to determine the age-structure of free-ranging dolphin groups. This work will aid monitoring the health of dolphin populations and inform timely conservation ...

Newly Discovered Jurassic Fossils in Texas

Scientists have filled a major gap in the state's fossil record -- describing the first known Jurassic vertebrate fossils in Texas. The weathered bone fragments are from the limbs and backbone of a plesiosaur, an extinct marine ...

New Research Finds That More Than 90% of Global Aquaculture Faces Substantial Risk from Environmental Change

Many of the world's largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark ...
