The Galapagos and other oceanic islands and Marine Protected Areas (MPAs) may be "critical" refuges for sharks in the Tropical Eastern Pacific, as predatory fish appear depleted in more coastal MPAs through fishing pressure

An international team led by Covadonga Orejas, a researcher at the Gijón Oceanographic Centre of the Spanish Institute of Oceanography (IEO-CSIC); Veerle Huvenne, a researcher at the UK National Oceanography Centre (NOC); and Jacob González-Solís, professor at the Faculty of Biology of the University of Barcelona, has published the first comprehensive study on the seamounts of the Cape Verde archipelago, their biodiversity, ecological functionality and socio-economic relevance in the journal Progress in Oceanography.

A new paper in Biology Methods and Protocols finds that we can now distinguish wild from farmed salmon using deep learning, potentially greatly improving strategies for environmental protection.

In a study now published in iScience, researchers from the University of Vienna (Austria), National Institute of Technology - Wakayama College (NITW; Japan), and Shimane University (Japan) present the largest cephalopod genome sequenced to date. Their analyses show that the vampire squid has retained parts of an ancient, squid-like chromosomal architecture, and thus revealing that modern octopuses evolved from squid-like ancestors.

An international study published in Nature Climate Change reveals that vast regions of the global ocean are experiencing compound state change, with simultaneously warming, becoming saltier or fresher, losing oxygen, and acidifying—clear indicators of climate change pushing marine environments into uncharted territory.

Estimating the multigenerational effects of chiral pesticide metabolites is essential for fully understanding their ecological impacts. This study demonstrated that S-o,p'-DDD accumulated preferentially in adult zebrafish and transferred more efficiently to their offspring compared to the R-enantiomer, leading to pronounced developmental defects and endocrine disruption across both generations. Molecular docking against key thyroid-related proteins provided a mechanistic explanation for this stereospecific toxicity. These findings suggest that evaluating only racemic mixtures may underestimate real-world hazards.

A massive, multi-year scientific expedition determined that land use on tropical islands can shape water quality in lagoons and that rainfall can be an important mediator for connections between land and lagoon waters. The scale of this research is sigificant: the researchers assessed at algal tissue nutrients, water chemistry, and microbial communities at nearly 200 sites around the island of Mo‘orea, French Polynesia, and repeated this sampling over multiple years.

Florida State University oceanographers have discovered a significant connection between small-scale microbial processes and ecosystem-wide dynamics, offering new insights into the mechanisms driving marine carbon storage.
