Summary: In highly fragmented and relatively stable cold-seep ecosystems, species are expected to exhibit high migration rates and long-distance dispersal of long-lived pelagic larvae to maintain genetic integrity over their range. Population genetics and larval dispersal modelling suggested that contemporary gene flow and larval exchanges are possible across the Atlantic Equatorial Belt and the Caribbean Sea, although probably rare. Additional studies using nuclear genetic markers and population genomics approaches are needed to clarify the evolutionary history and distinguish between ongoing and past processes for Atlantic bathymodioline mussels.

Summary: Using an axisymmetric immersed-boundary model, this study numerically investigates the fluid dynamics of a cephalopod-inspired propeller undergoing periodic inflation-deflation deformation in a low Reynolds number regime. A thrust-drag decoupling method is proposed based on physical analysis, allowing for the calculation of propulsive efficiency and systematic simulations are conducted to study the effects of Reynolds number and stroke ratio on force generation and efficiency. Results show that the propulsive efficiency of the propeller lies in the range of 11%-30% within the considered range of incoming-flow Reynolds number.

Summary: Understanding metapopulation dynamics is crucial for effective species conservation, but marine species are often overlooked due to difficulties in assessing connectivity in marine environments. Using Lagrangian Particle Tracking, the study assesses metapopulation dynamics of the Atlantic Mud Piddock (AMP) and provides spatial management measures for this threatened marine bivalve mollusk in Canada. The study reveals that sub-populations along the southern coastline of the Minas Basin are most strongly connected to other sub-populations, acting as sources and sinks of simulated larvae. The study emphasizes the need to protect critical source sites for the regional persistence of AMP and demonstrates the potential application of Lagrangian Particle Tracking in conservation planning.

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 serpulid worm Hydroides elegans is a model organism for studying marine biofouling, development, and larval settlement induced by microbial films. Settlement can be induced by natural biofilms, biofilms formed by specific bacterial species, or a bacterial extract. Larvae lose their cilia and undergo morphogenesis during the settlement process, which can be induced by a bacterial extract containing complex tailocin arrays. Loss of cilia before attachment may result in larvae being swept away by turbulent flows in marine habitats.

Summary: "English Summary: This study examines the effects of vertical behaviors on dispersal and connectivity of coral reef fish by combining observational data and individual-based modeling. The study finds that surface dwelling, ontogenetic vertical migration (OVM), and wide vertical spread are three prevalent behaviors among coral reef fish. Surface-dwelling behavior generally leads to more long-distance dispersal, lower local retention, and higher population connectivity compared to uniformly-distributed and OVM behaviors."

Summary: This study investigates the potential for adaptive evolution in larval size and swimming speed, two traits that may be related to dispersal outcomes in clown anemonefish. The researchers found strong evidence for the heritability of larval body size, but less conclusive evidence for the heritability of swimming speed. This work highlights the importance of considering prior distribution in Bayesian analysis and advances our understanding of potential dispersal-related larval traits.

Summary: Shark meat market in Brazil has experienced changes before and after the implementation of finning restrictions. The decline in domestic shark meat landings, increasing demand for seafood, and the commoditization of shark meat have facilitated import growth. As Brazil is an important player in shark meat consumption, domestic prices seem to influence imports, leading to potential overexploitation of sharks in poorly managed fisheries.

Summary: This paper analyzes the surface winds of ECMWF ERA5 reanalysis in the Atlantic Ocean. The study finds that ERA5 provides high-quality winds for non-extreme conditions, with some errors in tropical latitudes and locations following warm currents. Two calibration models, simple least-squares linear regression (LR) and quantile mapping method (QM), are proposed and compared to remove systematic bias. These models prove to be efficient in improving the accuracy of the reanalysis data.

Summary: Vertical mixing and hydrostatic adjustment are the two main mechanisms explaining the stability of the marine atmospheric boundary layer in regions with intense horizontal temperature gradients. This study utilized a coupled ocean-atmosphere numerical model to simulate the southwestern Atlantic Ocean region, and found that vertical mixing and warm-air temperature advection modulated the stability of the boundary layer. The results contribute to the understanding of air-sea interactions and the physical mechanisms controlling stability.
