Summary: Ocean acidification can negatively affect early-life stages of marine organisms, specifically in larval settlement and metamorphosis processes. This study found that seawater pH influences the growth and community composition of marine biofilms, impacting settlement success of marine invertebrates like the New Zealand serpulid polychaete Galeolaria hystrix. Overall, exposure to biofilms developed under reduced seawater pH conditions led to decreased settlement success in marine invertebrates.

Summary: Bacteroidetes bacteria found in sponges play important roles in enhancing sponge larval settlement. The bacteria utilize strategies such as forming biofilms, secreting molecules, and producing extracellular vesicles to significantly improve settlement rates. This enrichment of Bacteroidetes bacteria in sponges establishes a basis for reciprocal adaptive co-evolution between the microbial community and animals.

Summary: This article reviews current research on the connectivity of marine benthic macro-invertebrate populations and highlights some challenges and potential solutions. The study of a population of a trochid gastropod in an intertidal sandflat in Japan is used as an example to demonstrate the existence of source-sink relationships.

Summary: This study examines the relationship between genetic distance and dispersal distance in marine species. It finds that for species with long dispersal duration, dispersal distance is influenced more by ocean currents and shows no significant correlation with pelagic larval duration (PLD). Using a realistic ocean current model to estimate dispersal distance does not improve the correlation with genetic connectivity metrics compared to PLD. Possible explanations include the simplicity of the ocean circulation-based dispersal distance estimates and the limited predictive power of isolation-by-distance (IBD) slope for variation in dispersal distance among species with long PLD. Further research is needed to better understand the genetic diversity and spatial distribution of coastal marine organisms quantitatively.

Summary: Dispersal is influenced by interactions between an individual's phenotype and the environment, leading to complex variations in distances and directions of dispersal. Larval swimming behavior, along with other factors like depth and navigation, affects dispersal and settlement patterns, with faster swimming larvae showing increased probabilities of settlement and longer dispersal distances.

Summary: The study found that there is a biosynthetic loop of arginine-citrulline in sponge larval holobiont, where symbionts can synthesize arginine and larvae can convert arginine from seawater into NO and citrulline. The results support the holobiont complementation of the arginine-citrulline loop and NO biosynthesis in Amphimedon larvae, suggesting a critical role for bacterial symbionts in sponge development.

Summary: This study investigated the impact of connectivity and larval life history on marine metapopulation persistence in southeast Australia, finding that the number of local outgoing connections has the largest impact on metapopulation persistence. Results also suggested that the length of the pre-competency period is an influential parameter. Major hot spots of local connectivity contributing to multispecies persistence were identified in southeast Australia. The study emphasizes the importance of local connectivity patterns and larval competency characteristics in understanding and protecting real-world metapopulation persistence.

Summary: This study used larval dispersal connectivity to design networks of no-take reserves in Southeast Sulawesi, Indonesia. Different methods, such as decision trees and Marxan, were used to consider the setting and expansion of marine reserve networks at different scales. The study found that there were differences in priority areas for protection and expected benefits among different species, and that reef quality should also be taken into account when interpreting larval dispersal patterns and evaluating conservation measures.

Summary: This study assesses the role of contemporary oceanography and species traits in shaping observed patterns of biogeography at broad spatial scales. The research area covers the east and west coasts of North America, and the results show that the location of suitable habitat and the season of particle release play a significant role in determining the permeability of biogeographic barriers.

Summary: This paper introduces a spatial coalescence model to study the diversity of planktonic communities. By simulating a small number of individuals instead of the entire community, this approach is more time-saving and efficient compared to individual-based models.

Summary: Body size is a crucial trait for individual fitness and ecological processes. This study examined the cell size of ciliate communities across global oceans and found that cell size increased with latitude, following Bergmann's rule. The main drivers of this trend were temperature and prey size. The results highlight the importance of both biotic and abiotic factors in shaping the size distribution of marine ciliates, which are essential for pelagic ecosystem functions. The extensive dataset and predictive trends contribute to understanding the impact of climate change on pelagic ecosystems.

Summary: The study described the larval and early post-larval development of the mangrove cockle in laboratory conditions, as well as the effects of different microalgae on its growth and survival. Results showed that certain diatoms had better growth and survival rates for the mangrove cockle, while other microalgae may have been insufficient for larval culture of Anadara tuberculosa.

Summary: In this study, a biophysical model was used to assess the ecological connectivity of marine protected areas in the Yellow and East China Seas. The results showed that ocean dynamics and larval dispersal patterns had significant effects on connectivity. The existing national marine reserves in these regions were not well-connected, with nearly 30% of them being isolated. This study provides a scientific reference for future reserve planning and improving ecological connectivity in coastal China.

Summary: The trade-off between competition and colonization is an important mechanism for promoting the coexistence of competitors. However, the empirical evidence for this trade-off is not consistent. In order to improve tests of this trade-off, a framework is proposed that focuses on defining dispersal mode and competition type. This framework clarifies how these factors shape the trade-off in various systems and provides a common ground for researchers in different fields to assess the importance of this trade-off in shaping community structure.

Summary: Aquaculture of New Zealand's green-lipped mussel heavily relies on the wild mussel spat supply from Ninety Mile Beach in northern New Zealand. This study used a biophysical model to simulate the dispersal process of mussel larvae and identified primary settlement areas and potential source populations. The results revealed limited larval exchange between two geographic regions in northern New Zealand, with most spat collected at Ninety Mile Beach originating from neighboring mussel beds, particularly those at Ahipara. These findings provide important information for monitoring and protecting the key source populations and ensuring the sustainability of the mussel aquaculture industry in New Zealand.

Summary: Live animal gamma radioisotope tracing is a valuable tool for monitoring the real-time contaminant uptake and retention in individual animals for ecotoxicologists. A systematic review of current aquatic studies found shortcomings in experimental design and statistical approaches, leading to key recommendations for future researchers. Despite some studies not matching the statistical approach with the experimental design, most studies utilized the correct approach for analyzing data.

Summary: Stormwater runoff contains metal contaminants that pose a potential risk to water quality. During a storm, the concentrations of dissolved and particulate metals increase. Most of the metals exist in a complexed form during the storm, posing a lower risk of toxicity to aquatic organisms. Current water quality guideline values may be too conservative when assessing stormwater pollution risks from metal contaminants.
