Techniques developed to study the distant past—from dating ancient artifacts to reconstructing climate records in ice cores—are now being repurposed to better understand the lives of modern sea turtles. Using radiocarbon methods from archaeology, researchers show that sea turtle shell plates are biological time capsules that record signs of major environmental disturbances in the ocean.

As climate change reshapes Arctic food webs, ringed seals will swim into risky polar bear territory if the menu is varied enough. 

That’s the central finding of a new study published in Ecology Letters. UBC researchers tracked 26 ringed seals and 39 polar bears in eastern Hudson Bay, using GPS and dive information to analyze how the animals found, and avoided becoming, food. 

Researchers led by the Technical University of Munich (TUM) have created the first global atlas of the influence of tides on coastal rivers. The regions surrounding these coastal rivers are particularly susceptible to flooding, especially with advancing climate change. The freely accessible world map shows the effects at a glance.

A new shark deterrent developed at FAU could transform commercial fishing by dramatically reducing unintended shark bycatch. Created by Stephen Kajiura, Ph.D., the patent-pending device uses a simple zinc and graphite combination to generate a weak electric field that repels sharks without affecting target fish. Field tests have shown up to a 69% reduction in shark bycatch, offering a practical, low-cost solution to a persistent ecological and economic challenge.

A new study analysing two fossilised whale skulls from around 5 million years ago has revealed fragments of sharks’ teeth lodged inside them. This provides rare evidence of how sharks fed on whales in north European waters in prehistoric times.

Sea ice around Antarctica expanded for several decades until a dramatic decline in 2015. The reasons behind this are revealed by research from the University of Gothenburg.

The rocks beneath our feet are leaving a hidden signature in the shells of marine snails along Australia’s ancient coastline, according to new research led by Adelaide University scientists.
