Summary: Serpentinization-influenced hydrothermal systems, such as the Lost City Hydrothermal Field, have the potential for the origin of life. However, microbial habitability in these systems may be limited due to high pH, elevated temperatures, and low carbon concentrations. The fluid chemistry and isotope data from the LCHF indicate that all fluids are derived from a single endmember produced in the hotter, deeper subsurface without microbial activity. The spatial variability among the vents is influenced by biotic and abiotic processes along different flow paths.

Summary: Crus1, a type of antimicrobial peptide from deep-sea shrimp, effectively kills Gram-positive bacteria by inducing membrane leakage and structure damage in a pH, temperature, and disulfide linkage-dependent manner. Serine substitution of cysteine residues in the WAP domain does not affect bacterial binding capacity but completely abolishes the bactericidal activity of rCrus1.

Summary: This study investigates the significance of hydrothermal iron inputs to the oceanic Fe inventory and the potential changes in Fe isotopes during mixing of hydrothermal vent fluids and seawater. Results show that the iron isotopic signature of dissolved Fe is mainly controlled by oxidation of Fe(II) and precipitation of Fe-(oxyhydr)oxides.

Summary: This study implemented a novel experimental approach to assess the recovery potential of vent communities along the slow-spreading northern Mid-Atlantic Ridge. Within 2 years after inducing a small-scale disturbance, most taxonomic richness had recovered, but there was only partial recovery of faunal densities and a major change in faunal composition. The results suggest a potential role of mobile predators in early-colonisation stages.

Summary: The study investigates the ultra-high calcium concentrations and isotopic characteristics in hydrothermal fluids from the Lutao system in the north Luzon arc. It reveals the differences in chemical compositions between different vent fluids and the lack of significant calcium isotope fractionation during phase separation. The findings suggest the contribution of recycled marine carbonate and carbonate-rich subduction fluids to the calcium budget and isotopic variations in the system.

Summary: The study reveals the presence of different sizes of iron particles in the Mid-Atlantic Ridge hydrothermal system, where the nanoparticulate/colloidal phase changes with sample temperature and the distribution of iron particles of different sizes varies in the plume. The results support previous observations of dissolved iron in MAR vent plumes, suggesting that this recalcitrant iron pool contributes to maintaining high hydrothermal iron fluxes to the deep ocean. Unexpected findings in sample collection could have implications for further research.

Summary: Three hyperthermophilic methanogens, designated strain SG7(T), strain SG1 and strain SLH, were isolated from the deep-sea hydrothermal vent fields along the Eastern Lau Spreading Center. They belong to the genus Methanocaldococcus and are most closely related to Methanocaldococcus bathoardescens. The strains exhibit unique characteristics and are proposed as representatives of a novel species, Methanocaldococcus lauensis sp. nov.

Summary: In this study, a g-type lysozyme (LysG1) was identified and characterized from shrimp inhabiting a deep-sea hydrothermal vent. The recombinant LysG1 exhibited selective bactericidal activity against Gram-negative bacteria by binding to bacterial cell wall components and inducing cell lysis. Mutation analysis revealed the importance of specific protein helixes in the bacterial binding and killing activities of LysG1. These findings provide insights into the activity and mechanism of g-type lysozyme in crustacean and deep-sea organisms.

Summary: The study shows that seabirds segregate in trait space based on IUCN threat status, with threatened species having higher trait redundancy and non-threatened species having relatively limited redundancy. Species with narrow habitat breadths, fast reproductive speeds, and varied diets are more likely to be threatened, while species with no threats are non-pelagic specialists.

Summary: Long-term experimental investigations on the transgenerational plasticity (TGP) and transgenerational acclimatization to global change in marine invertebrates are sparse. The study revealed significant effects of ocean warming and acidification on sea urchins, with offspring from near-future climate conditions displaying smaller size and reduced physiological functions. The experiment also showed potential for genetic adaptation in surviving individuals after a pathogenic event, but raised concerns about negative parental effects and reduced population replenishment.

Summary: Contemporary climate change and biological invasions are two main drivers of biodiversity redistribution. Studies suggest that non-native species tend to outperform native species under warming and freshening conditions. Ocean warming is expected to facilitate future spread and success of non-native species, while increased freshening may have negative impacts on both native and non-native species in coastal marine ecosystems.

Summary: The study found that fish communities in high-intertidal pools remained resilient between historical and recent sampling periods, with no evidence of invasion. However, changes were observed in fish communities in lower shore pools, with decreases in species richness, abundance, and community similarity. This suggests that ongoing ocean warming may lead to changes in these communities.

Summary: Temperature plays a significant role in the success, duration, and dispersal of larval marine ectotherms. A study on two sea urchin species found that Centrostephanus rodgersii has expanded its range in a warming ocean, while Heliocidaris tuberculata has not. The difference in response may be due to differences in their thermal tolerance during the larval stage.

Summary: This study reveals that increasing water temperatures can affect the catchability of Atlantic salmon, leading to a decrease in catches at warmer temperatures and an increase in post-release mortality. Absolute catch and release mortalities are predicted to be low at cooler river temperatures, but can range from 6% to 14% at temperatures that may result in fishing closures.
