Summary: This study developed a data logger called C-HAT to track the behavior of American lobsters in their natural habitat. The C-HAT recorded the lobsters' triaxial acceleration, compass heading, and heart rate. The results showed that lobster heart rates were around 60 beats per minute at rest and increased to around 80 beats per minute during activity. The study also found that at least a third of their movement was in response to external stimuli. Additionally, a movement index based on acceleration was correlated with the distance traveled by the lobsters.

Summary: A baseline survey was conducted in 2018 to assess the contamination levels in American lobsters in the Northumberland Strait, Canada. The study found that most contaminants were below the set guidelines, except for elevated levels of arsenic in all age classes. Mercury and methylmercury exceeded guidelines in some cases, but there was no consistent pattern of contaminant accumulation. This study will serve as a reference point for future monitoring after the remediation of Boat Harbour.

Summary: Research shows that lysosomal stability and ethoxyresorufin O-deethylase (EROD) induction exhibit higher sensitivity in contaminated lobsters. Increasing the temperature did not shorten the recovery period, and lobsters exposed to dilbit experienced greater cellular impacts compared to those exposed to marine diesel. Furthermore, marine diesel exposure appeared to have more ongoing issues for the lobster fishery.

Summary: This study used acoustic telemetry to evaluate the influence of longline mussel farms on lobster movement behavior. The results showed that the time lobsters spent within a site, distance travelled, and walking speed did not differ between the farm and reference sites. The tagging method had an impact on walking speed during the first 24 hours, but did not affect the residence time and the distance travelled by the lobsters.

Summary: This study investigates the role of post-translational modifications (PTMs) in diversifying peptide structure and enabling flexibility within the cardiac neuromuscular system of the American lobster. The researchers examine the effects of different isoforms of myosuppressin on various components of the system and find that amidation plays a critical role in the peptide's ability to exert its effects. The data suggest that PTMs are important for peptide action and can result in significant changes at different levels of the system.

Summary: The Southern New England stock of American lobster is severely depleted, and the reasons could be increased mortality of larvae or juveniles, decreased larval production, or both. The study examined the mating success of female lobsters in Buzzards Bay and found that contrary to the initial hypothesis, mating success was higher in areas with a female-skewed sex ratio. Two alternative explanations for this spatial pattern are the immaturity or newly matured state of females in the inner Bay, and the low density of lobsters leading to mate-finding difficulties for mature females.

Summary: In 1999, the American lobster population in the Long Island Sound experienced a severe mortality event, causing profound and lasting impacts on individuals, their families, and communities. The lack of effective and comprehensive recovery or assistance plans, combined with challenges impeding fishery diversification significantly hindered the ability of lobstermen to adapt. The lessons learned from this case study can inform future action to address impacts and maximize adaptive capacity in fishing communities facing environmental changes and shifts in species distributions due to climate change and other anthropogenic factors.

Summary: During the 1990s, the lobster population off southeastern Massachusetts (SEMA) declined due to significant warming of the coastal waters. Rising ocean temperatures adversely impacted the survival and distribution of lobsters, causing a reduction in larval delivery to suitable habitat and increasing thermal stress on settled lobsters. This study emphasizes the implications of warming coastal waters on lobster population connectivity and provides insights on the mechanism by which climate change affects marine species recruitment.

Summary: The geometry of the Long Island Sound (LIS) affects the propagation of waves, leading to differences between western and eastern areas. The mechanisms governing wave formation and dissipation in the LIS are not well understood. Existing meteorological models fail to accurately capture wave statistics due to low resolution and limited ability to resolve the LIS coastline, thus modification of wind fields using in situ wind observations is necessary.

Summary: Species distribution models for marine organisms are increasingly utilized for spatial planning, conservation, and fisheries management. Various mathematical forms and physical/biological independent variables are used, with first-generation models mainly following linear or smoothing spline forms. Machine learning methods were used to evaluate different classes of variables, showing that physical and secondary production variables have the greatest contribution, while terrain variables have the least contribution. The presence and absence of species are defined by factors such as water depth, temperature, chlorophyll concentration, and specific zooplankton taxa, with strong seasonal variations.

Summary: The study utilized species distribution models to characterize the distribution of fish and macroinvertebrates in the US Northeast Shelf large marine ecosystem. It found that the biomass COG tended to shift to further offshore positions, while the occupancy habitat stayed at a regular spacing from the coastline. Both habitat types have shifted their along-shelf distances due to seasonal conditions.

Summary: One challenge in climate change communication is the lack of a direct link between the causes and impacts of global warming at local scales. High-resolution datasets on greenhouse gas emissions and temperature projections have helped identify regions with significant climate disparity across the globe, highlighting the widespread impact of warming despite localized emissions. Specific regions facing the greatest positive disparity include the polar arctic, Central Asia, and Africa, while negative disparity regions are found in western Europe, Southeast Asia, and eastern North America. Communication efforts that illustrate these disparities may help promote equity awareness, enhance public understanding, and encourage collective global action.

Summary: Scallops are a popular seafood with global demand surpassing supply, leading to significant imports of farmed products. Our study in the Northwest Atlantic revealed that optimal shell growth occurs within a temperature range of 10-15 degrees C, with pearl nets showing higher growth rates compared to lantern nets. Strategic temperature-based site selection and low density stocking can help mitigate intraspecific competition and reduce mortality rates during cultivation.
