Summary: In this study, the composition and erosion activities on coral blocks in two coral reef gulfs in the eastern tropical Pacific were analyzed, revealing that the balance between bioerosion and calcification activities depends on rich trophic needs and environmental conditions, suggesting the unpredictable impact of contributing species on habitats.

Summary: Cabo Pulmo reef is a well-managed marine protected area in the southern Gulf of California, with various important energy flows in the ecosystem. Research shows that the reef complies with attributes to resist disturbances, providing high-quality ecosystem services and attracting developers. Despite the system's resilience, unregulated human activities may impact the condition of the reef.

Summary: The study documents coral cover and composition in relation to sea surface temperature (SST) over the past 25 years in marginal reefs of Costa Rica's Eastern Tropical Pacific. A catastrophic coral die-off event occurred in 2009, driven by SST minima and likely by extreme harmful algal blooms, leading to a shift in coral composition and a lack of recovery in the subsequent decade. This highlights the need for resilience-based management and restoration strategies in the face of ongoing coral reef declines.

Summary: Six new alpha-pyrone meroterpenoids (1-6) along with six known compounds (7-12) were isolated from the gorgonian coral-derived fungus Aspergillus hiratsukae SCSIO 7S2001 collected from Mischief Reef in the South China Sea. Their structures were determined by spectroscopic analysis and X-ray diffraction data, and compounds 1-5 and 7 exhibited antibacterial activity, while compound 8 showed potent cytotoxicity against specific cell lines.

Summary: The oxygen content of the oceans has declined due to climate change, especially in oxygen-deficient zones. Climate warming simulations predict the expansion of these zones until at least 2100. The response of ocean oxygenation on longer timescales remains uncertain.

Summary: Dissolved oxygen concentration is a main limiting factor for benthic species distribution, and low oxygen conditions may occur in coral reefs of the Eastern Tropical Pacific. The Spatio-temporal changes of DO in coral reefs of Gorgona Island were characterized and the critical oxygen tension for Pocillopora capitata was calculated. Low DO conditions were due to upwelling, and hypoxic events sporadically occurred at 10 m depth. Oxygen conditions lower than 2.3 mg L-1 coincided with the deepest distribution of scattered colonies of Pocillopora. Hypoxic events could pose a threat if eutrophication increases.

Summary: The study investigated the daily and seasonal variation of species composition and abundance in the early stages of fishes in the La Azufrada coral reef on the Colombian Pacific coast. It found that night conditions had a stronger effect on the ichthyoplanktonic species than the observed changes in environmental parameters.

Summary: Fungal infections, which are a significant cause of morbidity and mortality in high-risk populations, currently lack effective vaccines. Recent studies have identified a fungal enzyme essential for pathogenesis and virulence, and surprisingly, fungal strains lacking this enzyme can induce immune-mediated protection in immunocompromised animal models. These findings have important implications for the development of fungal vaccines in the future.

Summary: The study aimed to reveal small-scale particle dynamics in the eastern tropical North Pacific through Po-210/Pb-210 disequilibrium. Results showed significant deficiency of total Po-210 in oligotrophic seas and fractionation between dissolved and particulate Po-210 and Pb-210 in the scavenging process.

Summary: This study assesses whether secondary calcification is driven by a contrasting seasonal pattern in the Eastern Tropical Pacific (ETP). The results show that low pCO2 and high Omega Ca and Omega Ar were measured during the rainy season. The composition of the calcifier community differed between seasons at Las Monas. Overall, the study demonstrates that anomalous and persistent high seawater temperatures can affect carbonate production by secondary calcifiers.

Summary: Research in the Eastern Tropical Pacific (ETP) region suggests the potential presence of Mesophotic Coral Ecosystems (MCEs), which are influenced by factors such as light availability and water transparency. Studies mainly focus on taxonomy, ecosystem function, and reviews, indicating a need for further research in areas such as environmental variable structure, molecular ecology, and natural resource management. Light availability is identified as a key driver for the bathymetric distribution of MCEs, although other local factors should also be considered for potential shifts in depth limits.

Summary: Research has found that there is no genetic structure among certain species in mesophotic coral ecosystems and there are hidden cryptic taxa. High gene flow suggests the possibility of connectivity and replenishment among these species. The study also suggests that environmental selection along shallow to mesophotic depth gradients may drive divergence in certain depth-generalist species. The research highlights the importance of gene flow in connecting different taxa within this relatively diverse Caribbean genus.

Summary: The microbial biogas network is stable in its overall functionality but may be impaired if key microorganism groups are affected. Bacteriophages are believed to alter the steering process of the microbial network. This study extracted virus-like particles from a biogas reactor and identified 375 metagenome-assembled viral genomes. The metavirome sequencing provided new genome sequence information for viral genetic diversity in biogas reactors.

Summary: Mesophotic gorgonians have evolved multiple times from old deep-sea lineages, while shallow-water species belong to younger lineages. The mesophotic gorgonian fauna in the studied areas is related to shallow-water counterparts in two clades, indicating diversification driven by bathymetrical gradient. Interestingly, mesophotic clades have diversified faster than either shallow or deep clades.

Summary: Confronting a sustained coral reef conservation crisis, a study was conducted on the benthic community, fish community, and genetic connectivity of main reef-building corals in Baru peninsula, Colombia. The study found a homogeneous fringing reef track with differences in coral composition between sites and depths. The reef system in the Non-Protected Area (NPA) exhibited high coral cover and can be considered a spatial refugia under climate change and Anthropocene conditions. The study suggests implementing a co-management scheme to protect this unique reef tract.

Summary: This study assessed the distribution of two common octocoral genera, Muricea and Leptogorgia, in the Equatorial Front region of the Tropical Eastern Pacific. The results revealed two hotspots of octocoral biodiversity, with Sea Surface Temperature being the main environmental factor influencing octocoral distribution. Muricea showed higher resilience to thermal fluctuations compared to Leptogorgia. The study discussed the potential roles of suitable substrates at specific depths, active photosynthetic radiation, and temperature in the occurrence of octocorals in these hotspots.

Summary: The study successfully visualized the in situ localization of single-copy genes in Flavobacteriia and planktonic samples from the North Sea using direct-geneFISH technique, revealing the distribution and functional differences of polysaccharide-degrading genes among different Polaribacter species. By broadening probe specificities, highly similar genes in yet unidentified taxa were also detected, enabling visualization of the functional trait in subpopulations across species boundaries. Such quantitative insight into the niche separation of flavobacterial taxa complements our understanding of the ecology of polysaccharide-degrading bacteria beyond omics-based techniques on a single-cell level.
