Losing Nemo: Almost all aquarium fish in the US are caught in the wild

University of Sydney
Peer-Reviewed Publication

Research has revealed that about 90 percent of marine aquarium fish sold by online retailers in the United States are sourced directly from wild populations. This reliance on wild capture threatens the sustainability of coral reef ecosystems and puts endangered and threatened species at greater risk of extinction.

New ocean research alliance to boost national collaboration

University of British Columbia
Business Announcement

The Pacific Marine Science Alliance Society (PMSA) has announced a three-year agreement with the Marine Environmental Observation, Prediction and Response Network (MEOPAR) designed to strengthen national ocean research collaboration across Canada’s three coasts.

UBC is one of five member universities of the PMSA, which owns and operates the Bamfield Marine Sciences Centre, and works to advance marine and coastal research, education and sustainability.

The new partnership, backed by $300,000 in funding from PMSA and MEOPAR, will help researchers better collaborate at regional, national and international levels to address crucial research challenges, including climate resilience, marine hazard prediction and sustainable ocean resource use. The collaboration will also prioritize Indigenous-led stewardship, student mobility and new international research partnerships.

Blackwater photos suggest new symbiosis between fish and anemones

Virginia Institute of Marine Science
Peer-Reviewed Publication

A new manuscript in the Journal of Fish Biology reveals that relationships between fish and sea anemones are more diverse than those portrayed in Finding Nemo. Captured through breathtaking blackwater photography, the images featured in the article show rarely seen encounters between these creatures that may provide mutual benefits.

Twin threat: Cascadia and San Andreas faults may be seismically linked

Oregon State University
Peer-Reviewed Publication

Two fault systems on North America’s West Coast – the Cascadia subduction zone and the San Andreas fault – may be synchronized, with earthquakes on one fault potentially triggering seismic events on the other, a new study found.

Lake Tahoe algae experiment suggests seasonal shifts ahead

University of California - Davis
Peer-Reviewed Publication

As the climate warms and nutrient inputs shift, algal communities in cool, clear mountain lakes like Lake Tahoe will likely experience seasonal changes, finds a UC Davis study.

Cooler warm periods: How the Southern Ocean controlled climate and atmospheric CO2

Helmholtz Centre for Ocean Research Kiel (GEOMAR)
Peer-Reviewed Publication

6 October 2025/Kiel. The Southern Ocean around Antarctica plays a decisive role in the global carbon cycle – and thus in the climate system. This is supported by a new study involving the GEOMAR Helmholtz Centre for Ocean Research Kiel, published today in Nature Communications. An international team has demonstrated that between 800,000 and 430,000 years ago, a stronger layering of the Southern Ocean prevented carbon dioxide from rising from the deep ocean into the atmosphere. As a result, temperatures were significantly lower than in later warm periods.

How different bird species forage together in the Antarctic

Duke University
Peer-Reviewed Publication

It’s a scene fit for a nature documentary: In the frigid ocean surrounding Antarctica, the water boils over as seabirds dive from above and marine animals like seals and whales rise from the depths to all feast on krill. But zoom out and this flurry of activity is just a tiny speck in a desolate seascape. Scientists have been puzzled by how these various species are all able to find the same food source at the same time. In research published October 6 in the journal Proceedings of the National Academy of Sciences, Duke University and UC Davis scientists tease out how multiple species of Antarctic seabirds forage together – with takeaways for conservation and for crowd behavior — and shows that flocks find food better when they rely on each other’s senses.

Marine heatwaves have hidden impacts on ocean food webs and carbon cycling

Monterey Bay Aquarium Research Institute
Peer-Reviewed Publication

A new study from researchers at MBARI and the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science—with an interdisciplinary team of collaborators from the Hakai Institute, Xiamen University, the University of British Columbia, the University of Southern Denmark, and Fisheries and Oceans Canada—has revealed the impacts of marine heatwaves on the foundation of the ocean food web. Pairing data from robotic floats deployed as part of the Global Ocean Biogeochemical Array with eDNA samples from ship-based plankton surveys, the team found that marine heatwaves can reshape ocean food webs, which in turn can slow the transport of carbon to the deep sea and hamper the ocean’s ability to buffer against climate change.

Warming oceans may pose a serious threat to American lobsters

Virginia Institute of Marine Science
Peer-Reviewed Publication

A new study published in Marine Ecology Progress Series reveals American lobster embryos can handle ocean acidification surprisingly well, but increased temperatures may pose distinct challenges for the species.
