Summary: Partial rbcL sequences were analyzed from type specimens of three early-described Corallina species. The results revealed that C. arbuscula and C. pilulifera are synonymous, with C. pilulifera being the accepted name, and that C. vancouveriensis is a distinct species. Additional species, C. hakodatensis sp. nov. and C. parva sp. nov., were also identified. These findings have important implications for the biogeography, evolution, and speciation patterns of coralline algae.

Summary: Porolithon is an ecologically important genus of crustose coralline algae, distributed abundantly in tropical and subtropical shallow margins of coral reefs. Sequence comparisons of type specimens and field-collected specimens reveal four unique genetic lineages, suggesting the absence of P. gardineri and P. craspedium in eastern Australia. Furthermore, four new species are discovered, distinguished by growth form, margin shape, and medullary system. Urgent documentation of the taxonomic diversity of Porolithon species is necessary due to their ecological importance and sensitivity to ocean acidification.

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: A multigene molecular phylogeny was conducted to study the genus Phymatolithon. The study revealed the polyphyletic grouping of two monophyletic clades within the Hapalidiales. As a result, a new genus, Phymatolithopsis, was established, consisting of three species. Phymatolithopsis is closely related to Mesophyllum and is distinct from Phymatolithon and boreal species assigned to Lithothamnion. Morpho-anatomical characteristics were used to differentiate Phymatolithopsis from Phymatolithon, including the origin of conceptacle primordia and the distribution of gonimoblast filaments in carposporangial conceptacles.

Summary: Crustose calcifying red algae (CCRA) play important roles in reef health in the tropics, but their diversity has been underestimated. This study used DNA barcoding to investigate the CCRA diversity in Guam and found a much higher species richness than previously assumed, with many potentially new species.

Summary: This study reveals the diversity of cryptic crustose coralline algae (CCA) species in the Taoyuan Algal Reef (TAR) in Taiwan, many of which are potentially new species or endemic to TAR. The TAR represents a unique hotspot of CCA taxa in Taiwan's waters. The variations in CCA assemblages in the TAR are influenced by geographic distance, sedimentation, and substrate type, indicating the importance of dispersal limitation and environmental selection.

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: The molecular studies revealed hidden diversity within the genus Lithothamnion, leading to the proposal of a new genus Roseolithon based on phylogenetic analysis. The integrative taxonomic approach helped identifying distinct morphological features characterizing the new genus.

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: This study reveals that the microbial community structure associated with P. onkodes generally displayed a degree of stability, and bleached algae was still able to induce larval settlement and metamorphosis.

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.
