Researchers discovered that SAR11 marine bacteria are organized into stable, ecologically distinct groups, adapted to specific environments such as coastal and open ocean. These findings provide new insights into the global ocean's life-support system and climate reactions to threats like pollution and ocean warming.
A new study from the University of Gothenburg reveals that trawling restrictions have led to a significant increase in marine life, particularly among filter-feeding species like mussels and soft corals. However, heat-sensitive species are declining at shallow depths due to warmer water temperatures, driven by climate change.
A new study reveals that a decline in ocean oxygen levels is disrupting mesopelagic fish populations and ecosystems. The findings suggest that these events could destabilize ecological balances, impair the ocean's role in carbon cycling, and threaten marine biodiversity and food security.
A new study reveals that industrial iron from coal and steel industries is altering the North Pacific ecosystem, leading to changes in phytoplankton growth and nutrient cycles. The research found that increased iron supply boosts spring phytoplankton blooms but also depletes other nutrients, resulting in a crash later in the season.
Researchers warn that artificial oxygen input cannot replace comprehensive water protection strategies. Technical approaches have shown promise, but risks include intensifying greenhouse gases and disrupting marine habitats. Climate protection and reducing nutrient inputs remain crucial for mitigating ocean oxygen loss.
A new study reveals that large apex species like tiger sharks and great whites are critical to healthy oceans, but their populations have plummeted by 71% in the past 50 years. Conservation efforts must prioritize protecting these ecological roles to maintain ocean balance.
Researchers studied a subpopulation of transient killer whales that prey on marine mammals in the open ocean. They found two distinct foraging behaviors: independent diving and coordinated groups hunting along submarine canyons.
A study published in Environmental DNA analyzed seawater samples from the Ogasawara Islands, detecting 124 unique fish species and 38 coral genera. The research highlights the importance of monitoring biodiversity in remote regions using efficient methods like eDNA sequencing.
A University of British Columbia study suggests that jellyfish size can influence their nutritional value. The researchers found that larger jellyfish tend to have higher levels of healthy fats, making them potentially more nutritious.
A recent UBC study has found that southern resident killer whales require high-energy prey to survive, with spring-run Chinook salmon being the most suitable. The study's findings have significant implications for managing both species and mitigating the decline of this critically endangered population.
Researchers found that small pelagic fish, such as herring and sardines, are a cheap source of nutritious seafood. These fish can provide essential micronutrients like iron, zinc, and omega-3 fatty acids to vulnerable populations in low-income countries.
Researchers at Kyoto University have developed a new method to detect intraspecies genomic diversity, or microdiversity, of uncultivated bacteria. This approach allows for a more comprehensive understanding of microbial ecology and evolution, as previously overlooked variations are now being studied.
Researchers found 61 out of 86 species threatened with extinction, with coastal sharks facing greatest conservation concern. Increased protections and international trade regulations are crucial to prevent extinctions among these species.
Great White Sharks have been avoiding a South African coastal region due to the presence of Orcas. Long-term sightings and tagging data show that Great Whites flee areas with high Orca activity, adopting a 'flight' strategy reminiscent of wild dogs in response to increased lion presence.
Researchers have compiled a dataset of microplastic abundance in the world's upper oceans, estimating 24.4 trillion pieces weighing 82,000-578,000 tons. The data fills gaps in global coverage and provides realistic amounts for assessing impact on aquatic organisms.
Researchers found pyrosomes form dense blooms that impact food web dynamics and contribute to organic carbon movement. They also provide habitat for other animals, including jellyfish and amphipods.
A 30-year study found that warming waters caused rapid shifts in connected marine ecosystems, with smaller fish moving northward and entire communities inverting. The research suggests that future warming events could have major impacts on marine ecosystems and fisheries.
Rhabdopleurids, tiny bottom-dwelling critters, have survived for over 500 million years by staying relatively unchanged. They predate ancient pelagic graptolites that went extinct 350 million years ago, highlighting the value of conservative evolution.
A study reveals that cod population increases in central Baltic lead to expansion into adjacent marginal systems, impacting local ecosystems through trophic cascades. This phenomenon underscores the importance of linking local and regional processes for ecosystem management.

The ecosystem's natural and human-related changes require effective management and mitigation strategies.
