Summary: This study evaluated the physiological responses of three macroalgae species from different intertidal levels to tidal regimes. Results showed species-specific physiological responses, with P. canaliculata exhibiting higher resilience and F. serratus being the most sensitive species. These findings indicate high susceptibility of low intertidal organisms to expected extreme climatic events.

Summary: Metabolic syndrome is a global public health issue, with seaweeds being highlighted as potential natural sources of bioactive compounds, particularly brown seaweeds which contain more bioactive components. Ascophyllum nodosum and Fucus vesiculosus are brown seaweed species with the highest antioxidant values and total phenolic content.

Summary: This study found that phlorotannins from Ascophyllum nodosum and Fucus vesiculosus significantly reduced blood sugar, cholesterol, and triglyceride levels in rats with hyperlipidemia. It also increased insulin and high-density lipoprotein cholesterol levels while promoting lipase activity. Moreover, phlorotannins reduced adipocyte size, decreased inflammatory factors, and increased antioxidant enzyme activity. These results suggest that Ascophyllum nodosum and Fucus vesiculosus could be potential sources of anti-hyperlipidemia drugs and functional foods.

Summary: Ulva macroalgae species, particularly Ulva rigida, produced in an open land-based integrated multi-trophic aquaculture (IMTA) system, show seasonal variations in protein, fat, dietary fiber, and ash content. Rich in potassium, magnesium, and iron, these macroalgae may have improved nutritional value under certain cultivation conditions and could potentially be used as a functional food ingredient to increase market value.

Summary: Sulfated polysaccharides known as fucoidans, obtained from brown algae, have attracted attention due to their biological activities. Fucus vesiculosus and Ascophyllum nodosum, both belonging to Fucales order, are popular sources of commercial fucoidans. Despite their similarities in chemical composition and biological actions, these fucoidans differ considerably in their polysaccharide mixtures. Carefully characterized structures from both fucoidans may have valuable applications in drug development.

Summary: In this study, an efficient adsorbent prepared from Fucus spiralis macroalgae was used for the removal of methylene blue dye from aqueous solution. The adsorbent exhibited a high adsorption capacity and the process was found to be spontaneous and endothermic. Response surface methodology was employed to optimize the dye removal and its accuracy was compared with artificial neural network method. The results suggested that Fucus spiralis-based adsorbent has potential for colored wastewater depollution.

Summary: This study investigates the seasonal variation of nutrients, eutrophication patterns, and Chlorophyll a (Chl-a) response in the coastal waters adjacent to Guangdong Province. The results show significant differences in Chl-a, dissolved inorganic nitrogen (DIN), and phosphorus (DIP) concentrations among seasons. It is necessary to strengthen integrated land and sea management to mitigate eutrophication and harmful algal blooms.

Summary: Low-molecular-weight metabolites known as mycotoxins from various fungal genera were studied in brown algae from the Kandalaksha Gulf, White Sea using enzyme immunoassay. F. vesiculosus was found to contain almost all detected mycotoxins in significant amounts, while P. canaliculata had lower levels of certain toxins compared to A. nodosum. L. digitata and S. latissima only contained trace amounts of ergot alkaloids, with no other mycotoxins detected.

Summary: In this study, the Auda marsh in Iraq was sampled to assess the seasonal dynamics and controlling factors of microalgae productivity. The research found that water temperature and turbidity were important factors in controlling phytoplankton productivity in the marshes, while nitrogen or phosphorous did not explain productivity well.

Summary: This study aimed to investigate the chemical and bioactive characteristics of Ascophyllum nodosum affected by seasonal variation and evaluate the potential benefits of alternative processing and utilization of side streams. The results showed that the chemical composition of the seaweed is linked to its reproductive state and alternative processing can increase its value.

Summary: This study investigates enzyme-assisted extraction (EAE) and ultrasound-assisted enzyme extraction (UAEE) methods for extracting polyphenols from brown macroalga Ascophyllum nodosum. The extraction yields and antioxidant activities of polyphenols were evaluated. The research identifies a suitable extraction process and polyphenols with antioxidant activities, supporting the expanded application of polyphenols from A. nodosum for nutraceuticals or pharmaceuticals.

Summary: Aquatic macrophytes serve as good biomonitors for trace elements, but they also capture suspended particulate matter, which may introduce bias in concentration measurements. Standardizing washing procedures for removing particulate matter from the moss samples is essential, and shorter washing times may be sufficient for cleaning the moss effectively.

Summary: Aquatic bryophytes have been used as pollution biomonitors, but standardized sample collection and preparation methods are lacking. We studied the effects of different storage methods on element concentrations in the moss Fontinalis antipyretica, and found that refrigeration was the simplest and most suitable method, although it caused an increase in mercury content.

Summary: Mercury contamination poses a global environmental problem due to its high toxicity and persistence, resulting in biomagnification and threatening wildlife and ecosystems. A study conducted along the North Atlantic coast of Spain over 30 years revealed a significant decrease in mercury concentrations in two coastal animal species. However, biomagnification still occurred, and nitrogen pollution affected stable nitrogen isotope ratios, limiting their use as indicators for biomagnification.
