Summary: This study assessed the performance of Durafet-based sensors in estuarine waters and found dynamic errors in the temperature and salinity responses of the internal and external reference electrodes. The errors were primarily driven by tidal mixing and were corrected using a dynamic sensor response correction method. The results showed that salinity change was the strongest limiting factor for the reference electrode response.

Summary: Seaweed farming is effective in buffering acidification, with different seaweed species showing varying capacities and intense fluctuations in pH within the aquaculture areas. The deficit in pCO(2), elevated levels of dissolved oxygen and Omega(arag) in seaweed farms are beneficial for calcifying organisms and can potentially provide important refugia from ocean acidification.

Summary: The study showed that in wild populations of long-lived species, immigrants have lower fitness than residents, with fewer breeding attempts, fledglings, breeding success, and recruits. This may be due to asymmetric limiting resources and the competitive ability of dispersers vs. non-dispersers, supporting female-biased dispersal in birds.

Summary: This study investigated the separate and interactive effects of pH and DIC levels on the red tide algae and their prey. The results showed that, except for the lowest pH of 6.8 combined with lower DIC concentrations, the effects of pH and DIC on these organisms were not significant. Therefore, the red tide algae appear to be resilient to changes in pH and DIC.

Summary: Infectious diseases are associated with impaired cognition in a variety of host species and cognitive abilities, leading to variation in cognitive performance within and among populations. This impairment can result from direct damage by the parasite, host immune response, or lost opportunities for learning. Additionally, factors such as stress and malnutrition that increase infection risk and impair cognition further compound cognitive impairment. However, essential questions about the frequency, duration, and fitness consequences of infection-linked cognitive impairment in wild animal populations, the specific cognitive abilities most affected, and the potential for adaptive evolution of cognition in response to the emergence of infectious diseases remain unresolved.

Summary: The study on how predation and tidal inundation influence recruitment of reef-forming oysters in eastern Australia showed that oysters recruited at all sites, but their density was affected by tidal inundation and caging. Abiotic factors like temperature, turbidity, dissolved oxygen, and biotic factors like predation can negatively influence oyster recruitment, suggesting that restoration projects should prioritize sites with favorable conditions or find ways to mitigate stressors.

Summary: The study reviewed bioconcentration of neuroactive pharmaceuticals in fish and the potential impact on ecosystems, finding that lipophilicity is not a reliable predictor for bioconcentration. Experimental parameters, species, and life stage significantly influence bioconcentration, with increased fish lethality correlating with higher bioconcentration. However, other effects such as growth, condition, behavior, and reproduction did not show clear correlations, likely due to insufficient and variable data.

Summary: The contamination of surface waters by pharmaceuticals is a global issue caused by increased access and use of pharmaceuticals, which poses a threat to non-target species. Neuroactive pharmaceuticals, in particular, can bioaccumulate in fish and disrupt various processes, impacting fish populations and their ecosystems. This study investigates the presence and bioaccumulation of 33 neuroactive pharmaceuticals in multiple fish species from four different estuaries. The results show widespread occurrence and bioaccumulation of these pharmaceuticals in fish tissues, highlighting the urgent need for toxicity assessment in natural ecosystems.

Summary: Chemical pollution poses a major threat to marine ecosystems, especially to top predators like sharks, which are highly susceptible to exposure and accumulation of contaminants. This study examined the contamination levels, composition, and sources in blue sharks inhabiting the Northeast Atlantic, as well as the potential risk to human consumers. High levels of contaminants were found in most sampled sharks, with over 75% exceeding legal limits for human consumption. Consumption of meat from these sharks could potentially expose consumers to dangerous levels of methylmercury. Moreover, the assessment of single contaminants may underestimate the risk to human health, and the accumulation of contaminants in sharks appears to be influenced by their geographical distribution rather than other factors such as sex, size, or prey trophic level.

Summary: This study aimed to determine if differences in contaminant body burden found in blue sharks from the Northeast Atlantic would result in differences in stress responses. The researchers found that sharks from the most contaminated zone exhibited more pronounced stress responses and similar differences were found in biomarker responses. These results suggest that blue sharks and these biomarkers have the potential to be used for pollution monitoring in different areas of the Atlantic.

Summary: This paper examines the potential positive and negative interactions between oyster reef restoration and oyster aquaculture industries. Three key factors influencing the strength and direction of interactions are identified: similarity of focal species, physicochemical and socio-economic environment, and open dialogue and consultation. Positive interactions can be maximized through shared infrastructure, resources, and knowledge, as well as utilization of marine spatial planning tools. Open and inclusive dialogue between industries and stakeholders is crucial for mitigating risk and maximizing positive synergies.

Summary: Marine artificial structures often have negative impacts on native species diversity and promote the presence of non-indigenous species. However, the addition of complex habitat and bioreceptive materials can help mitigate these effects. In this study, the effects of structural complexity and concrete mixture on recruitment were investigated. The results showed that complex tiles had less algal cover, while mixtures with oyster shell supported higher cover of sessile species. The non-indigenous ascidian Styela plicata dominated complex tiles at a low tidal elevation.
