Summary: This study used sequencing analysis to investigate the bacterial microbiota associated with different coral species and sediments, and their relationship with environmental variables. The results showed that the bacterial assemblages in different corals and sediments varied and were influenced by environmental factors. However, no significant differences were found in the bacterial assemblages between different sites for apparently healthy corals and sediments. The relative abundance of different bacterial families also varied in coral, sediment, and seawater samples.

Summary: We identified six opsins from a coral species, including three novel opsins. We characterized the properties of four of these opsins and found that opsins 1 and 6 can activate Gs-type G protein in a light-dependent manner, with maximum sensitivities at 472 nm and 476 nm, respectively. Opsin 4 can induce intracellular Ca2+ increases through light-dependency. Our findings reveal that corals possess multiple opsins that regulate light-dependent signaling through different cascades.

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 article provides the first reports of spawning activity by outplanted Acropora palmata colonies on reefs in Florida, USA. The observation of light spawning from A. palmata colonies in 2021 and 2022 indicates that restoration efforts for A. palmata may be close to achieving self-sustaining populations that can produce viable larvae. The gametes collected from the outplanted colonies yielded high fertilization rates and viable larvae, suggesting the potential for an increase in the population's genotypic diversity upon successful recruitment to the reef.

Summary: This study establishes a new high-resolution record of coral community development off southeast Florida during a period of variable climate in the late Holocene. The findings indicate that cold-sensitive reef-building coral communities expanded to the high-latitude reefs off southeast Florida during a period of regional warming, suggesting a link between regional oceanographic climate and the expansion of these coral communities. This has important implications for future range expansions of reef-building coral communities in response to modern climate change.

Summary: The worldwide decline in coral populations has led to the development of various coral conservation and restoration groups. This study compares the physiological condition of land-based nursery corals with wild conspecific populations. The findings show that nursery corals are similar in terms of metabolism, but differ in terms of biomass, symbiotic algae pigmentation, and Symbiodiniaceae populations, indicating substantial photoacclimation processes during outplanting.

Summary: Coral reefs worldwide are declining, but some populations in Palau, Micronesia are better adapted to survive in warmer and more acidic oceans. These coral populations can resist and recover from thermal stress better than their offshore counterparts. The difference in tissue biomass and energy reserves between the nearshore and offshore colonies may be explained by the increased metabolic demand of the warmer and more acidic nearshore environment. Despite the differences in symbiont species and prey availability, the lipid compositions of colonies from both habitats were similar. The regulation of colony biomass and energy reserves may be influenced by various factors, but they converge to a similar homeostatic set point under different environmental conditions.

Summary: The mucus membrane is the front line of defense against pathogens in corals. Understanding disease transmission in corals is complicated, but most of the established transmission pathways are associated with damage rather than evasion of immune defenses. However, this study suggests that ingestion may be an important pathway for the transmission of coral pathogens that bypasses the mucus membrane.

Summary: The declining coral populations worldwide require identification of risks and drivers leading to these declines. A predictive model for white pox disease (WPX) in Acropora palmata was developed using disease surveys and environmental data. The model revealed that colony size was the most influential predictor for WPX occurrence and water quality parameters and wind speeds also played a role. The model can support targeted management actions and disease surveillance.

Summary: As global temperatures warm, species must adapt to a changing climate or transition to a different location suitable for their survival. Understanding the extent to which species are able to do so, particularly keystone species, is imperative to ensuring the survival of key ecosystems. This study focuses on the ribbed mussel Geukensia demissa and how populations in different regions respond to temperature changes, using a combination of oxygen consumption assays and genomic divergence analyses. The results reveal differences in oxygen consumption and gene expression between mussel populations from Georgia and Massachusetts, emphasizing the importance of studying integrative patterns of genomic and phenotypic variation in key species and their response to climate change.

Summary: The study reveals positive relationships between mussel density and species richness, as well as between within-species genomic diversity and density of that species in freshwater mussel communities. However, it does not robustly support the expectation of correlated genomic and species diversity. This research advances the important frontier of community-wide genomic assessment and highlights the variability in relationships among different levels of organization and interactions with the broader ecosystem.

Summary: Symbiotic mutualisms are crucial for ecosystems and species, including reef-building corals. The benefits and nutrient exchange between corals and endosymbiotic dinoflagellates are influenced by environmental conditions. This study found that corals associated with Durusdinium trenchii or Cladocopium spp. exhibited similar nutrient exchange under normal temperatures, but heat-exposed colonies with D. trenchii experienced less physiological stress while maintaining high carbon assimilation and nutrient transfer. Contrary to prevailing notions, this suggests that high-functioning mutualisms can occur in host-symbiont combinations adapted to high-temperature environments.
