Summary: Seawater temperature rise due to climate change negatively impacts coral reef communities. The study investigated the response of Acropora tenuis larvae to thermal stress and its effect on their thermal tolerance during the juvenile stage. Larvae were exposed to different temperatures and their settlement success and survival were assessed. The results showed that larval thermal stress did not enhance thermal tolerance in juveniles, posing a potential threat to their resilience against heatwaves.

Summary: This study investigates the transcriptomic responses of coral during early life stages after inoculation with symbiotic algae and identifies possible symbiosis-related genes. Genes involved in immune regulation, protection against oxidative stress, and metabolic interactions are particularly important for symbiosis during early life stages. Molecular phylogenetic analysis suggests that gene duplication may have played a role in establishing stable mutualism in coral, and symbiotic molecular mechanisms may vary among different coral lineages.

Summary: Planula larvae of Acropora tenuis coral were successfully dissociated into single cells using a tissue dissociation solution, leading to the establishment of in vitro cell lines. Brown-colored cells proliferated transiently, while translucent and pale blue cells decreased in number. The brown-colored cells exhibited morphogenesis-like behavior and continued to proliferate stably, expressing a specific set of genes corresponding to different cell properties.

Summary: Elevated temperatures can cause coral bleaching and reef degradation. However, this study found that coral may have the ability to cope with thermal stress by producing more heat-tolerant larvae. The stressed coral fragments showed a trade-off in egg production, with an increase in egg number but a decrease in size. Additionally, larvae and recruits from the stressed colony had marginally higher survival rates in higher water temperatures, which may contribute to improving coral reef resilience.

Summary: Molecular phylogenetics has revolutionized our understanding of coral taxonomy, systematics, and biogeography. In this study, we used targeted capture sequencing to investigate the relationships of a coral clade containing the widely distributed species Acropora tenuis. Our analysis revealed 11 distinct lineages within the clade, with only four corresponding to known species. We also described two new species and removed five previously recognized species. Our findings highlight the limitations of traditional morphological taxonomy and have important implications for the conservation and management of reef corals.

Summary: Takifugu rubripes is an important fish in Chinese aquaculture due to its high-quality meat. Heat shock proteins (HSPs) play crucial roles in maintaining protein homeostasis in eukaryotic cells. This study compared two full-length cDNA sequences of HSP family in T. rubripes and found that TrHSP60 and TrHSP70-13 have the greatest homology with each other. The expression levels of these genes were influenced by temperature stress.

Summary: The study revealed that corals attract Symbiodiniaceae cells using ActL, with different strains of Symbiodiniaceae showing varying attraction to ActL. Juvenile polyps of A. tenuis acquire different numbers of Symbiodiniaceae cells, with the amount acquired correlating with the chemotactic activity of ActL.

Summary: An integrated Bayesian approach was used to determine which Florida reefs ranked highest in terms of Acropora cervicornis colony survival from 2012 to 2018. Results showed highly variable survival rates in different regions and reefs, with lower survival rates in reefs exposed to high wave energy and higher rates in Biscayne Bay. Spatial latent effects of low survival were detected, particularly between 2015 and 2017 in the middle and upper Florida Keys, emphasizing the need for strategic outplanting of nursery-reared colonies to optimize coral population recovery in Florida.

Summary: The study investigated the transcriptomes of coral and symbiotic dinoflagellates exposed to Irgarol to elucidate the molecular mechanisms underlying bleaching. Different gene expressions, pathways, and protein networks were disrupted by Irgarol exposure, affecting various biological processes in both coral and symbiotic dinoflagellates. This suggests that Irgarol disrupts gene expression and biological processes, leading to bleaching effect on corals and their symbiotic partners.

Summary: Coral reefs are being heavily impacted by ocean warming and acidification caused by human activities. Research has shown that coral survival may no longer be linked to their ability to calcify efficiently, as protein density and calcification rates may be sacrificed for coral genet survival.

Summary: In this study, 321 Zanclea colonies associated with 31 coral genera were analyzed to investigate the evolution and biogeography of this group. The results showed high genetic diversity of hydrozoans, with nine clades corresponding to cryptic or pseudo-cryptic species. While most Zanclea clades have a wide distribution across the Indo-Pacific, two host-specific clades were possibly found exclusively in the Red Sea. The lack of congruence between Zanclea and coral phylogenies suggests a lack of coevolutionary events.

Summary: This study provides a thorough morpho-molecular reassessment of the hydrozoan family Cladocorynidae, confirming the monophyly of the two nominal genera and describing a new genus exclusively associated with octocorals. The research suggests that symbiosis with octocorals likely appeared in the most recent common ancestor of Pteroclava and Pseudozanclea, with specific synapomorphies emerging in the most recent common ancestor of all cladocorynid taxa. Genetic analysis of Pteroclava krempfi colonies revealed high intra-specific variability and distinct clades based on host specificity and geographic distribution.

Summary: This article reports on ten species belonging to the genus Gonaxia found in recent collections from the deep waters of the New Caledonian region by the French Tropical Deep-Sea Benthos Program. The study used classical morphological approaches and included the first genetic characterization of the genus. Two new species were described, and additional notes on other species were provided. A new family, Gonaxiidae Maggioni, fam. nov., was proposed based on the multi-locus phylogenetic hypothesis of the Macrocolonia.

Summary: Species delimitation of corals is complex, requiring integrated genetic and morphological analyses, and sampling from a wide geographic range. In the case of the blue coral Heliopora, there are two valid species and distinct genetic lineages in different regions. This study highlights the importance of phylogenetic analysis using genome-wide markers and examining populations across their distribution range.

Summary: This review provides an updated overview of the compounds isolated from the octocoral family Alcyoniidae that exhibit potential cytotoxic activity. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was used to evaluate the bioactive compounds in vitro. The study found several compounds with stronger cytotoxicity than their positive control, and their mechanism of action remains to be investigated further.

Summary: Nudibranchs, carnivorous animals, have been observed to prey on various types of animals, including cnidarians such as hydrozoans. However, there have been no records of nudibranchs preying on symbiotic hydrozoans due to the protective action of the host. In this study, a newly described nudibranch species, Sakuraeolis marhe, was found feeding on Zanclea sp. 2, a hydrozoan associated with a bryozoan. This is the first well-documented case of a nudibranch feeding on a symbiotic hydrozoan, providing new insights into their trophic associations.

Summary: This study compared the identification performance of the 5' and 3' end COI regions in odonate species, with the 3' end region showing slightly higher variability. However, phylogenetic reconstructions, genetic distances, and diagnostic characters identification demonstrated similar discrimination power for both regions. Overall, the DNA barcoding inventory assembled in this study provides valuable insights into the systematics and conservation of odonate species, with implications for future monitoring-based studies.
