In a detailed review of the status of the world’s 126 […]

Satellite images show the dramatic reduction from 2008 to 2019 in the area covered by kelp forests (gold) off the coast of Mendocino and Sonoma Counties in Northern California. Credit: Meredith McPherson Most of Northern California’s kelp forest ecosystem is gone, replaced by widespread ‘urchin barrens’ that may persist long […]

Plankton-feeding fishes often dominate the fish assemblage on oceanic coral reefs. Credit: Dr. Christina Skinner Study reveals open ocean waters once assumed to be unproductive are in fact teeming with an abundance of life on coral reefs. Since Charles Darwin’s day, the abundance of life on coral reefs has been […]

The findings reveal that lacerations and abrasions, increasingly caused through collisions with […]

Māori wrasse are large, colorful fish that can be found on the Great Barrier Reef. In a ground-breaking new study, scientists used innovative molecular techniques to explain how corals on the east coast of Australia survived previous tough conditions—enabling the Great Barrier Reef to become the vast reef it is […]

A humpback whale. The songs of fin whales can be used for seismic imaging of the oceanic crust, providing scientists a novel alternative to conventional surveying, a new study published this week in Science shows. Fin whale songs contain signals that are reflected and refracted within the crust, including the sediment and […]

In warming waters, the demand for oxygen of many fish species will increase, progressively approaching the maximum oxygen supply capacity of their respiratory organs. New tool gauges impacts of warming waters on over 200 fish species. Warming ocean waters could reduce the ability of fish, especially large ones, to extract […]

Montastraea spawning, Philippines. Credit: James R. Guest Efforts to understand when corals reproduce have been given a boost thanks to a new resource that gives scientists open access to more than forty years’ worth of information about coral spawning. Led by researchers at Newcastle University, UK, and James Cook University, […]
