UrduBy analyzing 42 years worth of canned salmon, University of Washington scientists show that levels a common marine parasite rose in two salmon species in the Gulf of Alaska from 1979 to 2021. The rise may be a sign of ecosystem recovery, possibly influenced by the 1972 Marine Mammal Protection Act.

Rays were more diverse 150 million years ago than previously thought
In a new study recently published in the journal Papers in Palaeontology, an international team of scientists led by palaeobiologist Julia Türtscher from the University of Vienna has explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity – including a new ray species.
Alaskan island wolves caused a deer population to plummet
Wolves on an Alaskan island caused a deer population to plumet and switched to primarily eating sea otters in just a few years, a finding scientists at Oregon State University and the Alaska Department of Fish and Game believe is the first case of sea otters becoming the primary food source for a land-based predator.
What Ancient Underwater Food Webs Can Tell Us About the Future of Climate Change
UNLV analysis challenges the idea that ocean ecosystems have barely changed over millions of years, pointing scientists down a new path on conservation efforts and policy.
3D Innovareef: Sculpture to Restore Thai Marine Ecosystem
The Veterinary Medical Aquatic Animal Research Center of Excellence (VMARCE), Chulalongkorn University has created Innovareef—lifelike cement-based structures, convenient for planula settlement and growth, accelerating recovery of the coral reef ecosystem, promoting eco-tourism as well as functioning as smart stations for marine environmental monitoring.
Attack on 2 fronts leads ocean bacteria to require carbon boost
The types of ocean bacteria known to absorb carbon dioxide from the air require more energy – in the form of carbon – and other resources when they’re simultaneously infected by viruses and face attack from nearby predators, new research has found.
New Research Reveals Remarkable Resilience of Sea Life in the Aftermath of Mass Extinctions
Pioneering research has shown marine ecosystems can start working again, providing important functions for humans, after being wiped out much sooner than their return to peak biodiversity.
New Study Finds That Parasites Can Drain Energy from Hosts Prior to Infection
A new study by Scripps Institution of Oceanography at the University of California San Diego and the Norwegian University of Life Sciences has found that a species of brain-infecting parasite can disrupt the metabolism of its host—the California killifish—both before and after infection.
