Summary: In this study, we investigated the photosynthetic characteristics of the crustose coralline alga Pneophyllum fragile in response to elevated water temperature and irradiance. We found that P. fragile exhibited a distinct adaptability to high temperatures and strong irradiance, with increased photosynthesis capacity and respiration rate. The compensation irradiance and saturation irradiance also increased with increasing water temperature.

Summary: In this study, the researchers collected and classified chemical compounds produced by reef-building crustose coralline algae (CCA) and found that these compounds can induce coral settlement and increase larval survival. The study provides insights into the natural distribution of these compounds in coral reef habitats and offers potential applications for enhancing coral reef restoration.

Summary: Crustose coralline algae (CCA) are important for reef framework construction, but little is known about their growth and calcification in seasonal upwelling systems. This study assessed the growth and calcification rates of two dominant reef-building CCA species in a shallow coral reef in the Colombian Caribbean. Results showed higher growth and calcification rates during the upwelling season compared to the non-upwelling season. Seawater temperature was found to have an inverse relationship with CCA growth and calcification. These findings provide important baseline data and information for monitoring the impacts of environmental changes on tropical upwelling environments.

Summary: Coralliguous is one of the most important ecosystems in the Mediterranean Sea, supporting high levels of biodiversity. The study confirmed the primary role of crustose coralline algae as major builders of the Coralligenous, matching the evidence from the fossil record. It suggests considering the role of encrusting calcareous red algae in conservation and management policies.

Summary: This study explores the diversity and identification of crustose coralline algae (CCA) using different preservation methods and molecular biology techniques. The results show that CCA has immense diversity, with higher diversity in the inner layers compared to the outer layers. Among the molecular markers tested, the 23S rRNA and rbcL genes are more suitable for identifying algae, while the cox1 gene captures a broader range of diversity, including algae.

Summary: This study examined the percentages and rates of internal bioerosion by macroborer invertebrates in two dominant crustose coralline algae (CCA) species in the Colombian Caribbean. The results showed that rates of calcium carbonate removal by internal macroborers were higher in Lithoplyllum kaiseri compared to Porolithon antillarum, with mollusks identified as having the highest erosion activity. Despite no clear influence of climatic seasons on internal bioerosion, the high rates of CCA bioerosion may reduce reef consolidation in the region.

Summary: The skeletal density of high-latitude species of crustose coralline algae (CCA) significantly declined under future pCO2 conditions, potentially increasing their vulnerability to disturbance and impairing their ability to produce critical habitat in high-latitude systems.

Summary: Research shows that crustose coralline algae (CCA) respond negatively to low and medium emissions scenarios of warming and acidification, and may be adversely affected by 2030 if current emissions persist. Significant declines in growth rates and increases in bleaching were observed in the high emission scenario. These findings underscore the urgent need to take action to protect CCA and the valuable ecosystem services they provide.

Summary: A comparative study between a centuries-old manmade structure and the nearest natural reef at St. Eustatius in the eastern Caribbean found that the artificial reef had significantly lower species richness and fewer competitive interactions than the natural reef. The artificial reef was dominated by crustose coralline algae and zoantharians, while the natural reef was dominated by turf algae and fire corals. Significant differences in species composition were also found between exposed and sheltered sites on both reefs.

Summary: The study found that CCA is the dominant encrusting organism in reefs in Singapore, but its carbonate production rates are lower than most Indo-Pacific reefs and similar to other turbid reef systems. Reefs furthest from Singapore's main shipping port showed the highest CCA carbonate production rates, indicating that proximity to industrial areas and ship traffic may negatively impact encrusting calcifying organisms and CCA production rates in urbanized settings.

Summary: Research on encrusting reef organisms in two inshore island reefs of northern Western Australia revealed seasonal variations in CCA coverage but consistent carbonate production rates. Additionally, the study found in situ water temperatures exceeding coral bleaching thresholds and regular sea surface temperature anomalies over hotter months. Encrusters were deemed to play a vital role in reef carbonate budgets, potentially supporting net positive budgets through periods of temperature anomalies.

Summary: Crustose coralline algae (CCA) play a crucial role in coral reef development and replenishment, but their abundance is negatively affected by anthropogenic CO2 emissions. Surprisingly, diverse and well-developed coral reefs have been discovered in natural conditions where CCA and corals are not expected to thrive. This study focuses on the extreme environmental conditions in Bourake lagoon and finds that while CCA abundance decreases significantly, coral larvae settlement remains high, suggesting the potential for coral acclimatization and adaptation to global change.

Summary: Understanding how coralline algae acclimatize to ocean warming is important for their survival. Transplant experiments revealed that the growth and conceptacle production of the alga were higher in colder sites, but the thickness growth was higher in warmer sites at greater depth. Higher light irradiance negatively affected the growth and conceptacle production of the transplanted algae. Overall, the results suggest that the alga has good adaptability to warmer conditions.

Summary: This study investigated the impacts of warming and acidification on the growth, calcification, mineralogy, and photophysiology of the temperate articulated coralline alga, Calliarthron tuberculosum, using field observations and laboratory experiments. The results showed that calcification and growth of the coralline algae were negatively affected by warming and high pCO(2), while the photosynthetic rate increased. Furthermore, variation in Mg incorporation in cell walls of different cell types was documented for the first time in this species.

Summary: Standardized metrics are crucial for evaluating and monitoring coastal marine ecosystems. Calcification accretion units (CAUs) are a standardized tool for quantifying various response metrics in coastal marine habitats. CAUs consist of paired-settlement tiles that mimic different representative habitats. After deployment, CAUs are photographed and analyzed to evaluate calcium carbonate accretion rates.

Summary: Sinking large amounts of seaweed in the deep ocean is proposed as a promising strategy for removing carbon dioxide and mitigating climate change, but the lack of documentation for marketable carbon offsets through this method may lead to unintended environmental and social consequences. Urgent actions are needed to manage these risks.

Summary: This study examines the ability of marine macrophytes to mitigate ocean acidification and finds that Saccharina latissima, a type of seaweed, has the potential to significantly raise seawater pH and remove carbon dioxide. The study also shows that high irradiance and water residence time can optimize this acidification mitigation effect.

Summary: There is a growing interest in using seaweed to reduce methane emissions and improve animal health. A study was conducted to investigate the effects of Chondrus crispus on methane emissions and milk production in organic dairy cows. The results showed that feeding 6% C. crispus reduced methane production by 13.9% without affecting milk yield and composition.

Summary: This study investigated the economic and environmental costs of different seaweed cultivation platforms, cultivation strategies, and processing/end-use strategies. The dual-layer and strip cultivation systems had lower costs. Seaweed drying was the major contributor to economic and environmental costs. However, all scenarios had environmental benefits for marine eutrophication.
