Summary: This study investigated the composition and dynamic changes of bacterial communities in refrigerated Manila clams during their edible period. High-throughput sequencing revealed that Proteobacteria, Actinobacteriota, Acidobacteriota, and Chloroflexi were the major phyla present. The abundance of Proteobacteria increased with storage time, while Acidobacteriota and Chloroflexi decreased. No dominant genus was found during storage, but some genera showed significant changes over time. The results suggest that strategies targeting specific bacteria could improve the quality and safety of refrigerated clams.

Summary: Wildlife tourism, especially the feeding of animals, can have negative effects on their behavior and physiology. A study in Oslob, Philippines, found that whale sharks showed increased activity and metabolic rates during tourism operations. The research suggests that managers should focus on reducing energy expenditure through changes in operations rather than increasing food quantity.

Summary: The study demonstrates that there is a transition in the local response of precipitation to absorbing aerosols between the tropics and extra-tropics, while scattering aerosols have an impact on land and no effect over the ocean. The effects of absorbing aerosols are countered by the presence of land in both regions due to a reduction in surface latent-heat flux opposing diabatic-heating.

Summary: This article presents an energy-based model to explain how chronic stress increases disease risk and mortality. The model highlights the energetic cost of allostatic load and allostatic burden, suggesting that hypermetabolism may accelerate physiological decline and drive biological aging. The proposed transition from adaptive allostasis to maladaptive allostatic states is linked to the energetic restriction of growth, maintenance, and repair processes under stress.

Summary: In recent years, mass mortalities of cultured scallops have become more frequent in Peruvian bays, with hypoxic events being one of the main drivers. This study aimed to understand hypoxia in these bays and assess the ability of the Peruvian scallop to cope with reduced oxygen levels based on individual size. The research analyzed the relationships between dissolved oxygen saturation and other environmental parameters in bottom seawater, as well as the frequency and intensity of hypoxic events in two main culture areas, Sechura and Paracas Bays, to determine their relationship with scallop mass mortalities. Additionally, experiments were conducted to evaluate the survival time of two size groups of A. purpuratus under severe hypoxia conditions.

Summary: Individual traits and population parameters can serve as proxies for processes happening at different scales, enhancing our understanding of species responses to environmental changes. In this study, the effects of intertidal height and shore orientation on mussels were examined to understand individual and population dynamics. The results show significant impacts of these factors on individual traits and population parameters, with spatial variability influencing performance and processes at the population level. The findings suggest the importance of considering heterogeneous within-site conditions in modeling metapopulations with spatially explicit processes.

Summary: This study investigated the early response of juvenile king scallops to short-term exposure to toxic microalgae. The results showed that the scallops exhibited lower filtration and respiration rates and accumulated toxins during the exposure. There was also significant inter-individual variability in toxin accumulation potential. Furthermore, the ingestion of toxic algae was influenced by the recovery time from filtration inhibition and the filtration level. Proteomic analysis revealed changes in immune response and structural proteins in the mantle tissue of the exposed scallops.
