This research aimed to produce, on a multigram scale, a new class of non-toxic, halogen- and metal-free antifouling agents from the abundant lecithin byproducts of industrial soybean oil extraction. Three glycerophospholipid analogues were prepared by a facile methanolysis of crude soybean lecithins and a subsequent solvent-free O-alkylation: lysoglycerophosphocholines (LGPCs) and its ether derivatives -alkyl lysoglycerophosphocholines (ALPCs). As efficient antiproliferative agents, LGPCs and ALPCs are an eco-friendly alternative to current commercial antifoulants which possess significant toxicity to aquatic life. immersion tests of coated stainless-steel nets with previously incorporated automotive paint products, LGPCs and ALPCs (1--octadecyl-2--acyl--glycero-3-phosphocholine, ALPC18, and 1--hexadecyl-2--acyl--glycero-3-phosphocholine, ALPC16), in an aquaculture reservoir in SP-Brazil revealed significant growth inhibition against macrofouling species, especially the epibiotic golden mussel (), when compared with the control. These results promise a more sustainable and ecologically innocuous approach to combating the biofouling phenomenon and the deeply concerning dissemination of the golden mussel which has provoked an economic crisis in the energy and aquaculture sectors.

Biofouling in freshwater and marine environments developed on man-made aquatic surfaces causes significant economic losses. Still, this problem is magnified when it comes to invasive species, such as the golden mussel. One of the alternatives to combat it is the use of antifouling solutions; however, the vast majority focus on solutions for the marine environment.

The golden mussel (Limnoperna fortunei) is an invasive bivalve that has established itself in several South American river systems, impacting ecosystem functioning. Reservoir cascades provide their larvae with the means of rapid dispersal, but the relationship between environmental variables and larval stage structure remains unclear. In this study, the density of three L.

Article Synopsis
- Climate change is expected to change where freshwater fish and mussel species live, especially near hydropower dams.
- Warmer water will help more fish and mussel species thrive, but cold-water species will have less habitat.
- The cost to protect these species will go up in the Northwest but go down for many hydropower plants in the Southeast.
Article Synopsis
- Climate change is making heat waves and droughts worse, which is harming nature and people, especially in places like the Oder River in Europe.
- A toxic algae called Prymnesium parvum, also known as "golden algae," spread in this river and killed a huge amount of fish and other creatures because of pollution and high temperatures.
- This situation shows that because of warming and pollution, rivers can have more harmful algae problems in the future, and we need to think about this when planning for environmental changes.

Carotenoids are essential nutrients for humans and animals, and carotenoid coloration represents an important meat quality parameter for many farmed animals. Increasingly, studies have demonstrated that vertebrate carotenoid cleavage oxygenases (s) are essential enzymes in carotenoid metabolism and are therefore potential candidate genes for improving carotenoid deposition. However, our understanding of carotenoid bioavailability and s functions in invertebrates, particularly marine species, is currently quite limited.
