A new use for museum fish specimens
The discoloured fish that rest in glass jars in museums across the world are normally used by specialists as references to study the traits that identify certain species. But a new study proposes an additional use for such ‘samples.’ Published…
Melting glaciers will challenge some salmon populations and benefit others
A new Simon Fraser University-led study looking at the effects that glacier retreat will have on western North American Pacific salmon predicts that while some salmon populations may struggle, others may benefit. The research, published today in the journal BioScience…
Ship noise hampers crab camouflage
Colour-changing crabs struggle to camouflage themselves when exposed to noise from ships, new research shows. Shore crabs – the most common on UK shores – can change colour to match their surroundings. But University of Exeter scientists have discovered that…

Deep-sea fish community structure strongly affected by oxygen and temperature
Research on deep-sea fish density and diversity in the Gulf of California has implications for climate change
Satellite data boosts understanding of climate change’s effects on kelp
CORVALLIS, Ore. – Tapping into 35 years of satellite imagery, researchers at Oregon State University have dramatically enlarged the database regarding how climate change is affecting kelps, near-shore seaweeds that provide food and shelter for fish and protect coastlines from…
Scientists say it is time to save the Red Sea’s coral reef
The news in brief: 1) Red Sea corals and especially corals of the Gulf of Aqaba in the northern Red Sea may be one of the last reefs to survive the century. Scientists estimate 70 to 90 percent of all…

New research sheds light on the unique ‘call’ of Ross Sea killer whales
New Curtin University-led research has found that the smallest type of killer whale has 28 different complex calls, comprising a combination of burst-pulse sounds and whistles, which they use to communicate with family members about the changing landscape and habitat.…

Genetic resistance to lethal virus found in key farmed fish species
Resistance to a deadly disease that is affecting the second most farmed fish in the world has been found to be mainly due to differences in genes between families of the same fish. The breakthrough could help protect stocks of…
Scientists call on government to increase ambition to save our ocean
In the last decade there has been rapid expansion in the area of ocean designated as a Marine Protected Area (MPA). Despite this progress, marine biodiversity continues to decline, placing at risk the health of our oceans and the critical…
