Summary: Human trampling is a significant anthropogenic pressure in the rocky intertidal, affecting the beds of the mussel, Mytilus galloprovincialis, in NW shores of Portugal. The study discovered that the impacts of trampling varied among different taxa, with shell length of M. galloprovincialis increasing under high trampling intensity while abundances of Arthropoda, Mollusca, and Lasaea rubra decreasing. Additionally, total number of taxa and abundances of Nematoda and Annelida showed higher values under low trampling intensity. The findings have implications for managing human use in areas with ecosystem engineers.

Summary: Sea level has a significant impact on the intertidal zone, where organisms are exposed to atmospheric stressors at different times and frequencies. The timing of low water is crucial for the survival and growth of intertidal organisms, especially when they are emersed. Using shallow coral reefs as an example, this study investigates the coincidence of emersion with selected stressors in different locations along the Australian coastline. The results show that the timing of low water and emersion mortality risk varies seasonally and regionally, with a higher risk during the Austral spring. The study also highlights the importance of considering emersion history in assessing intertidal environments, particularly shallow coral reef habitats.

Summary: This study investigated the spatial distribution of total mercury (HgT) and methylmercury (MeHg) in Mediterranean mussels along the coasts of Turkiye's Black Sea, the Marmara, and Aegean Sea. The results showed a significant positive correlation between HgT and MeHg. The weekly intake of MeHg was found to be below the limits set by the FAO/WHO Joint Committee of Experts on Food Additives for both pediatric and adult consumers. The excessive consumption of mussels from areas with high MeHg concentrations posed a risk only for pediatric consumers.

Summary: This study evaluates the uptake and cellular effects of red polystyrene microplastics (MPs) in the gills of Mediterranean mussels. The results show that MP exposure leads to changes in amino acid and energy metabolism, disturbances in osmoregulatory processes, and cholinergic neurotransmission, as well as impairments in oxidative defense systems and lipid metabolism. These findings provide insights into the early time-dependent mechanisms of toxicity of polystyrene MPs in marine mussels and highlight the potential risks posed by MPs contamination to the environment and human health.

Summary: Biodiversity plays a crucial role in promoting ecosystem functioning, especially under extreme events caused by climate change. In this study, a regional-scale field experiment was conducted to investigate the response of intertidal communities to low tide aerial exposure and extreme temperatures. The results showed that evenness was the most important factor explaining variations in ecosystem functioning, while species richness and functional diversity had different effects under ambient and extreme temperatures. The short-term thermal history of the communities was identified as the best predictor of the biodiversity-ecosystem functioning relationship. The findings highlight the importance of biodiversity in mitigating the effects of extreme temperatures on intertidal communities.

Summary: The ongoing and interactive effects of climate change, overharvesting, and habitat loss on fish and fisheries have wide-ranging impacts on stakeholders who rely on sustainable fish resources. Successful responses to these threats require the involvement of stakeholders in developing solutions. This study examined the pro-environmental attitudes, behaviors, and climate change concerns of fisheries-based recreationists, focusing on activity type (recreational fishing, fish monitoring for citizen science) and specialization level. The results showed that citizen scientists exhibited stronger pro-environmental behaviors and attitudes, as well as greater concern for climate change, compared to recreational fishers and non-fisher/non-citizen scientists. However, overall, respondents showed greater concern for the environment than for climate change. The study highlights the importance of considering activity type and specialization level when promoting pro-environmental behaviors and climate concerns, and suggests that communication focused on healthy ecosystems may be more effective with some stakeholders than solely climate change messaging.
