Endangered Species
New research shows that endangered Kemp's ridley sea turtles are particularly attuned to the low-frequency sounds produced by ships and industrial activity in their coastal habitats. Scientists from Duke University, NOAA, and North Carolina State University measured the turtles' hearing and found peak sensitivity around 300 hertz, overlapping with common underwater noise sources. This discovery underscores potential vulnerabilities for the species amid busy shipping routes.

A camera trap survey in Indonesia's Leuser ecosystem has detected more Sumatran tigers than expected, signaling potential success in conservation efforts. The study found 17 tigers in 2023 and 18 in 2024, far exceeding averages from other parts of the island. This discovery highlights the importance of ranger patrols in protecting the critically endangered subspecies.
