Summary: This study explicitly examined spatial changes in Pocillopora damicornis-associated invertebrates in the southern Mexican Pacific. The results showed that the composition and abundance of invertebrates varied with spatial distance among coral heads. Higher similarity and variation were observed among coral heads within localities, but decreased as spatial distance increased, indicating a weak role for environmental sorting in these coral reefs.

Summary: This study evaluated the temporal changes in geobiological growth characteristics of corals in the Islas Marias archipelago in the eastern tropical Pacific, and found that human activities and thermal anomaly events have negatively affected coral growth. However, signs of recovery were also observed in certain areas and time periods.

Summary: This study investigated the concentrations and cycling of acrylate and DMSP in shallow-water coral reefs. The results showed that the concentrations of these compounds were low and did not differ significantly between the coral reef and open ocean. The heterotrophic community in the coral reef had a faster turnover rate compared to the open ocean, and the uptake rate of these compounds was higher during daylight hours.

Summary: Heat waves are causing declines in coral reefs globally. Coral thermal responses depend on multiple, interacting drivers, such as past thermal exposure, endosymbiont community composition, and host genotype. This study used DNA and RNA analysis to investigate gene expression patterns in Pocillopora corals across a historical thermal gradient, revealing the importance of host-photosymbiont specificity and host transcriptomic plasticity in thermal acclimatization.

Summary: This study presents a reconstruction of alkenone-sea surface temperature (SST) in the Eastern Pacific Warm Pool (EPWP) region, which shows local warming during global cooling periods. Climate model simulations suggest that ice sheet and greenhouse gas forcing weakened wind speeds over the EPWP, resulting in attenuated cooling effects on local SST. Spectral analysis indicates precessional pacing of warming spikes, possibly influenced by vernal equinox insolation. This work provides important insights into tropical Pacific glacial climate variability and the unique response of the EPWP to global climate forcings.

Summary: The study reveals that the El Nino-Southern Oscillation (ENSO) has diverse effects on vegetation in the west Pacific region, and different types of ENSO events lead to different vegetation anomalies, which are closely related to variations in precipitation and temperature.

Summary: In this study, the behavior of ITCZ convection near the eastern Pacific was investigated through analysis of satellite observations and reanalysis data. The study found that when precipitation peaks at the ITCZ center, there is a prominent positive peak in diabatic forcing, while when convection develops at the ITCZ edges, there is only a weak diabatic forcing but an import of moist static energy.

Summary: Gorgonian corals have complex interactions with microorganisms, and the microorganisms influence the lipidome of the corals. Lipids are likely transported from the microbial community to the coral host, and some lipid molecular species are derived from anaerobic bacteria. Symbiotic corals have higher storage lipids (triacylglycerols) compared to non-symbiotic corals.

Summary: The study found that the eastern Pacific El Nino has different influences on winter climate in the Far East. The warm winter is dominated by the western Pacific pattern, while the non-warm winter is dominated by the Pacific-North American pattern. Additionally, Indian Ocean warming follows the Indian Ocean dipole mode.

Summary: This study documents the daytime spawning of Pocillopora verrucosa across the two coasts of the central Red Sea, with spawning occurring 1-2 days before the new moon within a 25-day window between mid-May and mid-June. The timing of coral spawning from other species is likely to be similar given the reproductive synchrony observed in P. verrucosa across both coasts.

Summary: Anthropogenic climate change poses the biggest threat to coral reefs, but efforts to restore these ecosystems are helping to buy time. Research shows that lesion recovery is crucial for colony survival, with significant variability in healing observed among different genets of Acropora cervicornis from Florida reefs with varying thermal regimes. Results indicate that temperature stress significantly slows down lesion recovery, with corals from warmer reefs showing greater healing potential under heat stress compared to corals from cooler reefs.

Summary: The coastal and marine ecosystems in the unique environment of the Red Sea have adapted and flourished for millennia, providing socio-economic and environmental benefits to the bordering coastlines and countries. While the coral reef ecosystems in the Red Sea appear to be relatively healthier compared to global trends, they are still vulnerable to stressors such as increasing ocean temperature, acidification, and pollution. Degradation of marine habitats in many regions, coupled with increasing population pressure and coastal development projects, poses environmental costs and significant economic losses. Investment in blue natural capital and strategic development model focusing on the health of natural ecosystems can safeguard the sustainable development of the Red Sea.

Summary: The mustard hill coral Porites astreoides has recently experienced an increase in relative coverage across its distribution range in the Caribbean. The genetic structure of P. astreoides shows a complex spatial pattern, with both genetic homogeneity and differentiation existing simultaneously, possibly due to mixed reproductive strategies, among other factors.

Summary: The study conducted rapid, standardized heat tolerance assays on 229 colonies of Acropora cervicornis using coral bleaching automated stress systems, revealing a broad thermal tolerance range among individuals within the population, with highly reproducible rankings across independent tests. This suggests a potentially dominant role of fixed genetic effects in setting thermal tolerance and widespread distribution of tolerant individuals.

Summary: This study investigated the susceptibility and potential resilience of two coral recruits to SCTLD. The results showed that Colpophyllia natans recruits were more susceptible to SCTLD compared to Diploria labyrinthiformis recruits, and larger recruits and chimeras had higher survivorship. However, both species of recruits were unable to develop absolute resistance even after repeated exposures. This study highlights the importance of understanding the impact of SCTLD on coral recruits and its implications for reef restoration efforts.

Summary: The study reveals the cophylogeny between corals and their algal symbionts, supporting the presence of five coral species hosting different types of algae in the Mo'orea reef.

Summary: This study examined the effects of parental bleaching on symbiont community composition and offspring size in Montipora capitata. The results showed that parental bleaching history influenced the symbiont community composition in parents, gametes, and larvae, and larval size was also affected by maternal effects. These findings suggest that larval recruitment from bleached parents may decline as ocean warming becomes more frequent and severe, leading to generational shifts in symbiont community.

Summary: Climate change is changing coral reef ecosystems by causing more frequent and severe bleaching events. Some reefs, particularly Pocillopora colonies with thermotolerant algal symbionts, have shown higher heat resistance after severe bleaching. However, this state may not be long-lasting unless global greenhouse gas emissions and global warming are reduced.

Summary: Climate change-amplified marine heatwaves can lead to extensive mortality in foundation species. However, the lack of longitudinal genomic datasets has hindered the understanding of how rapid selection events alter hidden genetic structure. Heatwave impacts may be worsened in obligate symbiotic species, where the genetics of multiple coevolving taxa may be affected.
