Urban fish look fine, but their genes tell a different story
Blue damselfish appear thriving along Okinawa's urbanized coastlines, maintaining vibrant populations despite heavy human impact. However, a closer look at their gene activity reveals hidden physiological costs to living in these altered environments. Researchers studying these marine organisms are uncovering the subtle, long-term impacts of urbanization on marine biodiversity. While visual population counts suggest resilience, genetic analysis uncovers significant stress.
