Summary: The study found that all aerial organs of cauliflower are rich sources of health-promoting bioactive compounds, including GLS, phenolics, and flavonoids exhibiting antioxidant capacity. The highest contents of phytochemicals and antioxidant capacity were found in the leaves. Cauliflower organs are also rich in nutritive compounds, including minerals, proteins, and amino acids.

Summary: This study analyzed the distribution and anthropogenic contribution of 15 rare earth elements and yttrium (REY) in marine bivalves collected from two potentially polluted sites in Southern Norway. The results showed enrichment of light rare earth elements (LREE) over heavy rare earth elements (HREE) in the soft tissues of the organisms, as well as negative cerium and small positive gadolinium (Gd) anomalies. The study also found a high Gd anomaly downstream of the industry producing gadolinium-based MRI contrast agents, indicating biotic uptake of excess anthropogenic Gd.

Summary: Willow species have potential for restoring Cd-polluted sites due to their high biomass production and Cd accumulation capacities. This study identified several willow genotypes that were insensitive to Cd and showed high Cd induction, making them suitable for phytoremediation. Additionally, genotypes 2372, 51-3, and 1052 exhibited high Cd uptake and translocation capacities, providing valuable approaches for Cd-contaminated soil restoration with willows.

Summary: This study examined body part naming across six Japonic languages using a multi-method approach, revealing significant differences in terminology and semantics. The research also found a flatter hierarchical structure for parts of the face compared to parts of the body, and greater stability in bounded body parts across languages. The data suggest that there is not a universal conceptualization of the body across languages, highlighting the need for further in-depth explorations of understudied languages.

Summary: The study on the brown macroalga L. spicata reveals seasonal variations in photosynthetic activity under fluctuations in solar radiation, with increased photosynthetic capacity during summer and higher levels of photosynthetic pigments under greater solar irradiance, indicating high photoacclimation and photoprotective capacity in the species.

Summary: This study optimized broodstock conditioning and successful induced spawning of Tawera elliptica, describing the developmental process from embryos to early larval stage. The results suggest that conditioning in a water circulation system for 48 days is suitable for this species.

Summary: The study found that marine ecosystems in the Arctic and Antarctica may be impacted by short- and long-term human metal pollution. Brown macroalgae are reliable metal-biomonitoring organisms. There was no clear relationship between metal accumulation and photosynthetic performance in the macroalgae studied.

Summary: Research findings indicate a continuous reduction in the P. oceanica meadows near the city of Alicante, Spain, both in the long term and over the past 20 years, particularly in terms of coverage and density at the upper limit of the meadow. Additionally, there has been a significant increase in dead matte cover in the same period. The co-occurrence of various coastal impacts has contributed to the regression of the meadow.

Summary: In contrast to other coastal regions, the giant kelp ecosystem in southwestern Patagonia has remained stable in terms of area and biodiversity. The study analyzed the spatiotemporal variability of sea surface temperatures (SSTs) in this region and found that cold events caused by glacier melting, extreme winds, and planetary-scale events have contributed to counteracting global warming trends. The study highlights the importance of southwestern Patagonia as a potential climatic refugium for the giant kelp ecosystem, although freshwater inputs and storm turbulence may pose new challenges.

Summary: Arthrospira maxima is a commercially important filamentous cyanobacterium rich in valuable cellular products. This study investigated the effects of pH and temperature on its growth conditions and demonstrated its tolerance to a range of pH conditions and hyper-accumulation of pigments at low temperatures. The study also introduced a new purification method for the production of phycocyanin from A. maxima.

Summary: Globally, species distributions are shifting in response to environmental change. Many taxa, including marine species, are showing poleward range shifts as the climate warms. However, in the Southern Hemisphere, circumpolar oceanic fronts can present barriers to dispersal. The recent discovery of buoyant kelp rafts on beaches in Antarctica demonstrates the possibility of long-distance dispersal events. This study uses high-resolution phylogenomic analyses and oceanographic modeling to show that such events in the Southern Ocean are not rare.

Summary: Artificial cultivation of clams as an alternative to natural extraction is discussed in this paper. The study explores species-specific research and the effects of culture parameters on the development of larvae. Specific methods for inducing spawning and the impact of culture densities on yield are also examined.

Summary: This study investigates the ecophysiological responses of the intertidal kelp Lessonia spicata in different seasons of a year in the Pacific Ocean. The results show that light and nutrient availability, influenced by seasonal changes, affect the photosynthetic capacity and antioxidant activity of the kelp. Higher irradiance during spring and summer leads to increased photosynthesis and antioxidant activity, while lower concentrations of nitrate and phosphorous are observed in winter. Climate change is expected to increase irradiance and water temperature and decrease nutrient availability, which could positively impact the productivity and photoprotective abilities of the kelp.

Summary: This study evaluated the short- and long-term cellular tolerance responses in two brown macroalgae species of Dictyota genus under controlled laboratory conditions. The results showed that high salinity values induced changes in photosynthetic parameters and oxidative stress measurements, but did not cause significant damage to the photosynthetic apparatus. These findings contribute to the understanding of cellular tolerance strategies in Dictyota spp. and their potential use in biomonitoring desalination impacts in the field.

Summary: This study conducted transplantation experiments to investigate the physiological responses of two brown macroalgae species to desalination brine exposure. The results showed that the photosynthetic activity of the algae was inhibited and oxidative stress was induced by the brine. This study provides valuable data for assessing the potential impacts of desalination brine on coastal ecosystems at a global scale.

Summary: Harmful Algal Blooms (HABs) are a global problem that has been increasing in frequency in the Southeast Pacific region of Chile. The types of HABs in Chile include toxic HABs and ichthyotoxic HABs, with a lack of knowledge about harmful algal species in the Chilean Humboldt Current system. The occurrence and impacts of HAB events in Chile have been analyzed over a 65-year period, with diatoms, dinoflagellates, and silicoflagellates being the main causative microalgae species. The frequency of HAB events appears to be associated with monitoring efforts.

Summary: Codium fragile, an invasive seaweed, has successfully colonized coastal habitats in temperate regions but is rarely found in lower latitudes. In a study conducted in Chile, Codium was primarily found in mid and high tidepools, with larger individuals in the high intertidal pools and reproductive individuals in mid tidepools. The presence of Codium in these habitats can be attributed to lower consumer pressure and its tolerance to extreme environmental conditions.

Summary: In this study, the ecophysiological and cellular responses of Z. chilensis to hypersalinity conditions caused by desalination were evaluated. It was found that the seagrass can withstand higher salinities, but due to its limited distribution and ecological importance, direct brine discharges to Z. chilensis meadows are not recommended.
