Australian government announces 24 expeditioners based at research station on Macquarie Island will be evacuated over possible ‘prolonged psychological stress’

A dolphin has died from H5 bird flu in South Australia, marking the second native mammal species known to have contracted the virus.

It comes as the federal government announced it would withdraw researchers from the sub-Antarctic Macquarie Island research station due to the “psychosocial risk” of witnessing potential mass seal deaths from H5N1 during the upcoming seal breeding season.

Hundreds of experts write to environment minister calling for stronger protections for ‘unique and distinct’ marine ecosystems

The Australian government has been accused of leaving waters near the mainland largely unprotected by establishing the bulk of highly protected marine parks in remote areas.

More than 270 leading marine scientists from 84 research institutes have written to the environment minister, Murray Watt, urging stronger protections for marine ecosystems, as a once-in-a-decade review of marine parks gets under way.

Florida sets record for sea turtle nests but Trump move could stall recovery

Loggerhead turtles abound this season but rollback of Endangered Species Act protections could threaten future

Wildlife groups in Florida are celebrating record numbers of sea turtle nests this season, but experts warn Donald Trump’s recent gutting of the Endangered Species Act (ESA) could reverse decades of their recovery from the edge of extinction.

With more than two months of the summer nesting season still to run, loggerhead turtles have already laid 13,770 nests, hundreds more than recorded in any previous year, along an 8.5-mile stretch of shoreline monitored by the Loggerhead Marinelife Center in Juno Beach, on Florida’s Atlantic coast.

Marine conservationist says deliberate attack would be ‘act of extreme cruelty’ against endangered population

Spanish officials have launched an investigation after the matriarch of an orca pod known for jostling and ramming boats off the Iberian Peninsula was spotted with wounds suggesting she had been shot by a pellet gun.

On Friday, Spain’s environment ministry said Toñi, the oldest living member of the pod, had been seen swimming in the Strait of Gibraltar with markings on her dorsal fin that were “consistent with shots from a pellet gun”.

Research identifies 808,585 viral genomes belonging to what scientists estimate to be 362,802 different viruses

More than a decade after the human microbiome was comprehensively mapped, scientists have now identified the vast communities of microbes that make up the Great Barrier Reef.

Analysing DNA from seawater samples of 48 reefs, researchers have mapped the microbiome of the Great Barrier Reef, documenting more than 360,000 distinct viruses as well as more than 500 new bacterial species not previously known to science.

Dolphin deaths in South Australia spike after algal bloom decimates food sources

The March 2025 marine disaster may be linked to a high number of dolphin deaths in the region, scientists say

The number of dead dolphins washing up on South Australian beaches spiked in 2025, according to long-term data that reveals mortalities during the state’s devastating algal bloom were the highest in 12 years.

Last year, at least 70 carcasses of common and bottlenose dolphins were found across South Australia, with a further 20 reported in 2026, including the recent death of a popular Port River dolphin known as Zoom.

Drones are detecting more sharks at US beaches, but do they make the public safer?

Posted on by

Increase in sightings may not reflect increase in sharks with little evidence that threat to swimmers has risen

Experts say that despite recent increased investment in drones to monitor for sharks in states like New York, the machines have limited usefulness as a public safety tool and there does not appear to be evidence that the threat to swimmers from sharks has increased.

There have, however, been more reports of sharks around local beaches.

Pacific gray whales facing ‘catastrophic’ die-off as climate crisis hits food supply

Posted on by

Trump administration urged to relist a species in ‘very, very serious trouble’ under Endangered Species Act

Climate change is driving a gray whale “catastrophic mortality event” in the Pacific Ocean as melting sea ice depletes food sources and the animals starve, environmental groups warn.

Meanwhile, a range of other issues, like ship strikes, oil spills, microplastic pollution, algal blooms and Russian harvesting are also probably contributing to the die-off that has nearly halved the whales’ estimated population. It fell from 20,000 in 2019 to fewer than 13,000 this year, and the deaths appear to be accelerating.

Species’ ingenious survival strategies no match for human destruction, red list reveals

Newly endangered animals include desert frogs and snails in extreme ocean depths, both threatened by mining

Life has colonised every corner of the planet by evolving ingenious survival strategies but these are increasingly being overwhelmed by destructive human activities, this year’s red list of endangered species has revealed.

Many snails, limpets and clams have adapted to life at crushing depths in the oceans on hydrothermal vents where water temperatures can reach 450C (842F). But an assessment for the red list found that two-thirds of the hundreds of mollusc species found only on deep sea vents were at risk of extinction because of deep-sea mining.

Norfolk Island’s unique corals under triple threat from disease, El Niño and now government-approved dredging

Exclusive: Most of the island’s corals are likely to be species that have not been formally described by science, researcher says

Scientists fear unique corals that fringe Australia’s remote Norfolk Island could disappear because of a triple threat of disease, El Niño and a federal government plan to dredge a neighbouring shipping channel.

A failure to manage sediment and pollution washing into bays from cattle farming, cleared land along with wastewater has been blamed for widespread disease and outbreaks of algae over the corals.

Experts worked in ocean midwater off Brazil at near-record speeds thanks to cutting-edge tech

A marine biology expedition in international waters off the coast of Brazil has discovered 31 new species in just two weeks.

The researchers believe the speed at which the species were found and identified may be a record, in part because of the cutting-edge technology designed and built by the science and engineering team. For the first time on board a ship, the researchers were able to observe the living 3D cellular structure of microbial life thanks to a technological breakthrough nicknamed the Squid.
