A three-year experiment found that mixotrophs evolved to be less photosynthetic at higher temperatures, potentially increasing CO2 production and contributing to climate change. The study also suggests natural selection has a stronger effect on organisms with less flexible characteristics.
Marine aquaculture systems can provide a nutrient-rich alternative to terrestrial agriculture, reducing ecological impact and freshwater usage. Microalgae-based aquaculture offers high protein content and micronutrients without land or water requirements.
Researchers studied lamprey, an ancient fish that can live in freshwater and seawater, to understand how animals adapted to freshwater habitats. They discovered a hormone similar to prolactin that regulates salt transport proteins, enabling the lamprey's survival in freshwater.
Researchers confirm significant increase in freshwater entering the Arctic Ocean via the Bering Strait, leading to a decrease in saltiness and potential impacts on sea ice formation and regional ecosystems. This change could also affect climate-sensitive processes, such as deep water mixing in the North Atlantic.
A major new study is investigating the effects of beavers on the Arctic landscape, other animals, and local Indigenous communities. The project aims to understand the complex interlinkages between ecological and sociological changes as beaver numbers increase.
Mariculture holds great potential to help satisfy global demand for meat, but requires careful governance and efficient operations. The study suggests that finfish and shellfish farms can increase seafood availability, while maintaining ecosystem health.
A recent study found that yellow perch can expel microplastics from their bodies, but the process reduces nutritional value and alters liver function. The fish also experienced changes in gut microbiota communities and reduced body protein and mineral levels.
A new 9-step blueprint has been developed to improve the use of genetics and breeding strategies in aquaculture species, aiming to strengthen food security and meet growing global demand for fish. The guidelines also aim to address concerns over fish stocks, mercury levels, and farmed fish nutritional value.
Researchers from National Institute for Environmental Studies identified that radiocesium accumulates primarily in organic soil layers and stagnant water, contaminating organisms. Fertilizing contaminated areas with potassium can suppress biological absorption of radiocesium.
Researchers found that sulphur mollies create surface waves to deter predators, with the wave number decreasing capture probability. The collective behavior has anti-predator benefits, providing protection from bird attacks.
Three new species of freshwater goby fish have been identified in Japan and the Philippines, with distinct color patterns indicating separate lineages. The researchers believe that different color patterns play a crucial role in maintaining these separate lineages during courtship and mate selection.
A study published in Biology Letters reveals a drastic fall in the number of aquatic insects in the Paraná River basin due to dam construction. The research, conducted over 20 years, found that dams alter the nutrient balance and provide a clearer water environment, making insects more vulnerable to predation.
