gathering in unusually large groups and engaging in mating behaviour.

The footage, gathered between 2019 and 2023, provides one of the most detailed records of harbour porpoise mating behaviour ever documented in UK waters.

Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbour such a wide range of stripes, spots and patterns? A study conducted by the University of Liège reveals that this explosion of colour patterns is not the result of chance. The more species a reef is home to, the more varied the patterns, and fish from different oceans often end up looking alike, guided by the same deep biological constraints.

A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health unexpectedly collapses after appearing stable for long periods. By merging network theory with population genetics, the research identifies detectable "early warning signals" in genetic data that can alert conservationists to an approaching crisis before it becomes irreversible. These findings provide a practical toolkit for monitoring wildlife populations and protecting the genetic diversity essential for animals to survive a changing environment.
